Assessing the Acceptability of Less Invasive Caries Removal Techniques for treating Deep Carious Lesions: A Conjoint Survey among Dentists Practicing in a Midwestern American State. Caries Res 2023; 57:243-254. [PMID: 37699363 DOI: 10.1159/000533658] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Accepted: 08/09/2023] [Indexed: 09/14/2023] Open
Abstract
This study identified factors that influence dentists' decisions regarding less invasive caries removal techniques such as stepwise removal (SW) and selective removal (SE) using a marketing research technique, conjoint analysis. A survey was sent to 1,434 dentists practicing in Iowa. Dentists were randomly assigned to receive a questionnaire to rate the likelihood they would use either SW/SE in hypothetical clinical scenarios. The scenarios were carefully created by conjoint design and included three relevant attributes: depth of lesion, hardness of carious dentin, and patient age. Descriptive and conjoint analyses were performed to assess trade-offs between these attributes, using SPSS. The study revealed that depth of lesion was the most important factor in the dentists' decisions (49 importance value) when choosing a SW to treat a deep carious lesion, followed by hardness of carious dentin and patient age (21 importance value). For the SE group, depth of the lesion was also the predominant factor when selecting a treatment. The study also identified that a high proportion of dentists (24.9%) indicated they would never consider using SW or SE under any circumstances. Our survey showed that depth of lesion was the most important reason to select a less invasive caries removal method. The high proportion of dentists indicating they would never consider selective caries removal (SE) techniques suggests that these less invasive options are underutilized.

Generalized permanent dentition fluorosis severity becomes less evident over time among a birth cohort. FRONTIERS IN ORAL HEALTH 2023; 4:1198167. [PMID: 37456361 PMCID: PMC10348053 DOI: 10.3389/froh.2023.1198167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Accepted: 06/19/2023] [Indexed: 07/18/2023] Open
Abstract
Objectives There are relatively few cohort studies which have examined changes in fluorosis appearance over time, and none of these have assessed changes in generalized fluorosis. In this analysis, we quantified and assessed changes in multiple measures of generalized fluorosis severity through childhood, adolescence, and young adulthood. Methods Participants were from the Iowa Fluoride Study, a birth cohort recruited from 1992 to 1995. Permanent dentition fluorosis exams were carried out at ages 9, 13, 17, and 23 years using the Fluorosis Risk Index (FRI). Generalized fluorosis was assessed using mean FRI scores at the tooth- and person-level as well as a five-category measure of generalized fluorosis. Generalized fluorosis prevalence and severity was summarized at each time point and differences in adjacent time points were assessed using gamma statistics, signed-rank tests, and plotting changes in generalized fluorosis between adjacent time points. Results We observed a statistically significant decline in the percentage of non-zero mean FRI scores at later exam ages at both the person- and tooth-levels. Based on our five-category generalized fluorosis measure, there were 34.0%-54.1% of participants with generalized fluorosis at baseline for each tooth group, and these percentages declined to 8.9%-27.2% at the age 23-year exam. Conclusions We observed a statistically significant decline in generalized fluorosis severity scores and overall prevalence at later exam ages across all three measures of generalized fluorosis severity. This trend should be accounted for when estimating the prevalence of fluorosis in a population using fluorosis severity data collected in children and adolescents.

Patterns of fluoride intake from 6 to 17 years of age: The Iowa Fluoride Study. J Public Health Dent 2023; 83:18-25. [PMID: 36251680 PMCID: PMC10006287 DOI: 10.1111/jphd.12542] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 06/17/2022] [Accepted: 08/09/2022] [Indexed: 11/29/2022]
Abstract
OBJECTIVES This article reports on estimated daily fluoride intake from water, other beverages and selected foods, dentifrice, and dietary fluoride supplements by both individual sources, and all sources combined, among 787 children participating in the Iowa Fluoride Study (IFS) from 6 to 17 years of age. METHODS Total daily fluoride intake (mg F) and fluoride intake per kilogram bodyweight (mg F/kg bw) were estimated using responses to questionnaires sent every 3-6 months. Dietary assessments included frequencies and amounts of beverage intake for the previous week from water, milk, ready-to-drink beverages, beverages made by adding water to concentrate or powder, and selected foods with substantial water content. Descriptive statistics and bivariate and multivariable analyses with linear mixed models were used to assess associations with each of mg F and mg F/kg bw. RESULTS Mean combined dietary fluoride (mg F) from all sources examined in the study increased slightly with age, whereas the fluoride intake per kg bw decreased with age. Age, sex, and socioeconomic status were significantly associated with fluoride intake (mg F and mg F/kg bw). Each year increase in age was associated with a 0.02-mg increase in fluoride consumption, on average, after adjusting for the effects of covariates. CONCLUSIONS Daily mean fluoride intakes from single and combined sources were relatively stable, while the intake of fluoride per kg bw decreased from 6 to 17 years of age. Fluoridated water was the major source of ingested fluoride, contributing over 50% of total daily intake at all ages.

Prevalence of non-cavitated lesions and progression, regression, and no change from age 9 to 23 years. J Public Health Dent 2022; 82:313-320. [PMID: 35781658 PMCID: PMC9544189 DOI: 10.1111/jphd.12538] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Revised: 04/01/2022] [Accepted: 06/08/2022] [Indexed: 11/28/2022]
Abstract
OBJECTIVES Some non-cavitated caries lesions (D1 ), the initial stage of caries, progress to cavitation. This article reports participant-level and surface-level D1 prevalence and changes in status of D1 lesions through different periods from age 9 to 23. METHODS The Iowa Fluoride Study (IFS) participants were followed longitudinally; all permanent tooth surfaces were examined clinically for caries at ages 9, 13, 17, and 23 using standardized criteria for sound (S), questionable (D0 ), non-cavitated (D1 ), cavitated (D2+ ), filled (F), or missing due to decay (M). D1 lesions at the beginning of each interval were reassessed at each follow-up age to determine transitions (to the 5 categories or no transition). RESULTS The sample had relatively high socioeconomic status (SES), with about 52%-55% high SES, 32-35% middle SES, and 12-13% low SES. Person-level prevalences of D1 lesions were 23%, 38%, 60%, and 45% at ages 9, 13, 17, and 23, respectively. Surface-level prevalences were less than 1% at ages 9 and 13, 3% at 17, and 2% at 23. Thirteen percent of D1 s at age 9 progressed at 13, 18% progressed from 13 to 17, and 11% progressed from 17 to 23. The percentages regressing (to sound or D0 ) were 72%, 54%, and 72%, respectively. CONCLUSION Non-cavitated lesions were more prevalent at age 17 than at ages 9, 13, and 23. The high rates of regression compared to progression or no change suggest that many non-cavitated lesions do not progress to cavitated lesions and could be reversed; therefore, surgical intervention should not be the treatment of choice for incipient lesions.

Associations between body mass index and body composition measures in a birth cohort. Pediatr Res 2022; 91:1606-1615. [PMID: 33972687 PMCID: PMC8578575 DOI: 10.1038/s41390-021-01562-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Revised: 04/15/2021] [Accepted: 04/20/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND Associations among body composition measures have been limited to cross-sectional analyses of different subjects. We identified cross-sectional relationships between body mass index (BMI) and other body composition measures and predicted body composition measures from BMI throughout childhood and adolescence. METHODS BMI was calculated and % body fat (%BF), fat mass index (FMI), and fat-free mass index (FFMI) were measured using dual-energy x-ray absorptiometry at ages 5, 9, 11, 13, 15, and 17 years in a birth cohort (n = 629). Sex-specific body composition measures were calculated for BMI-for-age percentiles; associations between BMI and body composition measures were characterized; and body composition measures were predicted from BMI. RESULTS %BF, FMI, and FFMI generally increased with BMI-for-age percentiles at each age. Correlations between BMI and %BF or FMI were generally higher at BMI-for-age percentiles ≥95% than for lower BMI-for-age percentiles. Correlations between BMI and FFMI were generally higher for participants at very low and very high BMI-for-age percentiles than at moderate BMI-for-age percentiles. Age- and sex-specific predictions from BMI are provided for %BF, FM, and FFMI. CONCLUSIONS Sex-specific body composition measures throughout childhood and adolescence are presented. BMI is a better indicator of adiposity at higher than at lower BMI values. IMPACT Sex-specific body composition measures throughout childhood and adolescence are described. % BF, FMI, and FFMI generally increased with BMI-for-age percentiles for both sexes throughout childhood and adolescence. BMI is a better indicator of adiposity at higher BMI levels than at lower BMI values throughout childhood and adolescence.

Abstract
Purpose: The purpose of this study was to assess the relationship between the number of teeth present at 12 months and decayed, missing, or filled surfaces (dmfs) at 30 and 48 months. Methods: Data are from a longitudinal, multisite study with clinical dental examinations conducted at 12, 30, and 48 months of age. Spearman correlation and chi-square tests assessed relationships between teeth present at 12 months and dmfs at 30 (n equals 1,062) and 48 months (n equals 985). Results: Spearman correlations were weak but significant for both 30- and 48-month time points (R equals 0.066, P=0.032; R equals 0.093, P=0.004, respectively). Mantel-Haenszel chi-square analyses of categories of teeth present at 12 months (zero, one to four, five to eight, and greater than or equal to nine) and categories of dmfs at 30 and 48 months (zero, one to two, three to five, six to 15, and greater than or equal to 16) revealed nonsignificant (P=0.326) relationship with 30-month dmfs but a significant (P=0.013) relationship with 48-month dmfs. Conclusion: Results suggest that early tooth eruption is weakly associated with an occurrence of early childhood caries.

Effects of fluoride intake on cortical and trabecular bone microstructure at early adulthood using multi-row detector computed tomography (MDCT). Bone 2021; 146:115882. [PMID: 33578032 PMCID: PMC8009824 DOI: 10.1016/j.bone.2021.115882] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Revised: 01/28/2021] [Accepted: 02/07/2021] [Indexed: 11/18/2022]
Abstract
PURPOSE The aim of this study was to examine the effects of period-specific and cumulative fluoride (F) intake on bone at the levels of cortical and trabecular bone microstructural outcomes at early adulthood using emerging multi-row detector computed tomography (MDCT)-based novel techniques. METHODS Ultra-high resolution MDCT distal tibia scans were collected at age 19 visits under the Iowa Bone Development Study (IBDS), and cortical and trabecular bone microstructural outcomes were computed at the distal tibia using previously validated methods. CT scans of a tissue characterization phantom were used to calibrate CT numbers (Hounsfield units) into bone mineral density (mg/cc). Period-specific and cumulative F intakes from birth up to the age of 19 years were assessed for IBDS participants through questionnaire, and their relationships with MDCT-derived bone microstructural outcomes were examined using bivariable and multivariable analyses, adjusting for height, weight, maturity offset (years since age of peak height velocity (PHV)), physical activity (questionnaire for adolescents (PAQ-A)), healthy eating index version 2010 (HEI-2010) scores, and calcium and protein intakes. RESULTS MDCT distal tibia scans were acquired for 324 participants from among the total of 329 participants at age 19 visits. No motion artifacts were observed in any MDCT scans, and all images were successfully processed to measure cortical and trabecular bone microstructural outcomes. At early adulthood, males were observed to have stronger trabecular bone microstructural features, as well as thicker cortical bone (p < 0.01), as compared to age-similar females; however, females were found to have less cortical bone porosity as compared to males. Among participants with available F intake estimates (75 to 91% of the 324 with MDCT scans, depending on the period-specific F intake measure), no statistically significant associations were detected between any period-specific or cumulative F intake and bone microstructural outcomes of the tibia at the p < 0.01 level. Only for females, statistically suggestive associations (p < 0.05) were found between recent F intake (from 14 to 19 years) and trabecular mean plate width and trabecular thickness at the tibia. Those associations became somewhat weaker, but still statistically suggestive, for trabecular thickness in fully adjusted analysis with height, weight, PHV, calcium and protein intake, and HEI-2010 and PAQ-A scores as covariates. CONCLUSION The findings show that the effects of lifelong or period-specific F intake from combined sources for adolescents typical to the United States Midwest region are not strongly associated with bone microstructural outcomes at age 19 years. These findings are generally consistent with previously reported results of IBDS analyses, which further confirms that effects of lifelong or period-specific F intake on skeletons in early adulthood are absent or weak, even at the levels of cortical and trabecular bone microstructural details.

Beverage Intakes and Toothbrushing During Childhood Are Associated With Caries at Age 17 Years. J Acad Nutr Diet 2021; 121:253-260. [PMID: 33109505 PMCID: PMC7855000 DOI: 10.1016/j.jand.2020.08.087] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2020] [Revised: 08/19/2020] [Accepted: 08/24/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND Sugar-sweetened beverages (SSBs) have been associated with childhood caries; however, associations among lifelong beverage intakes and adolescent caries have received less attention. OBJECTIVE To investigate associations between beverage intakes during childhood and adolescence and caries experience at 17 years of age, while adjusting for fluoride intakes and toothbrushing. DESIGN Descriptive model analyses were conducted on data collected from a longitudinal birth cohort study. PARTICIPANTS/SETTING Participants included Iowa Fluoride Study members (n = 318) recruited at birth between 1992 and 1995 with at least 6 beverage questionnaires completed from ages 1 to 17 years and a caries examination at age 17. EXPOSURE Predictors included mean daily milk, juice (100% juice and juice drinks before age 9), SSB (including juice drinks after age 9), and water/sugar-free beverage (SFB) intakes; daily fluoride intakes; and daily toothbrushing frequencies for ages 1 to 17. MAIN OUTCOME MEASURES The outcome was dental caries count at age 17, adjusted for the number of scored tooth surfaces (decayed and filled surfaces attack rate [DFSAR]). STATISTICAL ANALYSES PERFORMED Univariable generalized linear models were fit for each predictor and the outcome DFSAR. Multivariable models assessed combined effects of beverage types, fluoride variables, toothbrushing, sex, and baseline socioeconomic status. RESULTS Based on multivariable models, each 8 oz of additional daily juice and water/SFB decreased expected DFSAR by 53% (95% confidence interval [CI]: 17%-73%) and 29% (95% CI: 7%-46%), respectively, and 8 additional oz SSBs increased expected DFSAR by 42% (95% CI: 5%-92%), after adjustment for other beverage intakes, toothbrushing, total fluoride intake excluding SSB fluoride (non-SSB total fluoride), sex, and baseline socioeconomic status. Each additional daily toothbrushing event decreased expected DFSAR by 43% (95% CI: 14%-62%) after adjustment for beverage intakes, non-SSB total fluoride intake, sex, and baseline SES. CONCLUSIONS Higher juice and water/SFB intakes and more toothbrushing were associated with lower caries at age 17, while higher SSB intakes were associated with higher caries.

Abstract
Our objective was to identify sex-specific age 5- to 17-year body composition (body mass index (BMI), % body fat, fat mass index, fat-free mass index) trajectories, compare trajectories assigned using age 5 (AGE5) data to those assigned using all available (ALL) data, and compare BMI assignments to other body composition assignments. Cluster analysis was used to identify low, medium, and high trajectories from body composition measures obtained from dual energy x-ray absorptiometry (DXA) scans at 5, 9, 11, 13, 15, and 17 years in a birth cohort followed longitudinally (n = 469). Moderate agreement was observed for comparisons between AGE5 data and ALL data cluster assignments for each body composition measure. Agreement between cluster assignments for BMI and other body composition measures was stronger using ALL data than using AGE5 data. Our results suggest that BMI, % body fat, fat mass index, and fat free mass index trajectories are established during early childhood, and that BMI is a reasonable predictor of body composition appropriate to track obesity in public health and clinical settings.

Abstract
OBJECTIVES To assess the occurrence of treatment under general anesthesia (GA) for dental caries among American Indian (AI) children from a Northern Plains tribal community. METHODS As part of a follow-up study of ECC, dental records for children age 6-8 years were evaluated. Descriptive statistics were generated, including the number of dental visits, extent of treatment, and whether the treatment was completed under GA. RESULTS Data were obtained from 95 dental records. The age of dental visits varied from 15 months to 8 years. Of the 95 children, 79 (83.2%) received dental treatment under GA at least once; 24 (25.2%) did so two or more times. The majority of the treatment involved extractions and placement of stainless steel crowns. CONCLUSIONS A large number of AI children received dental treatment under GA; many did so multiple times. Given the high cost of this treatment, even modestly effective preventive strategies such as silver diamine fluoride could yield cost savings.

Abstract
Dental fluorosis occurs from overingestion of fluoride during tooth formation. However, there is little evidence in the literature on whether or how fluorosis prevalence and severity change over time after tooth eruption. Permanent dentition dental examinations were conducted at ages 9, 13, 17, and 23 as part of the Iowa Fluoride Study, which has followed a cohort from birth. Fluorosis was assessed using the Fluorosis Risk Index (FRI) and Russell's criteria for differential diagnosis. Measures of fluorosis severity at the person and tooth level were calculated: second highest FRI score at the person level (the maximum FRI score for each tooth was determined and the tooth with the second highest maximum FRI score was used) and highest FRI score at the tooth level. At both the person and tooth levels, a decline in mild to moderate fluorosis severity was observed across adolescence and young adulthood. Across each pair of adjacent examinations at the person level, for participants with a baseline second highest FRI of 0, most participants stayed at 0 (82% to 91%). Many participants with a baseline second highest FRI of 1 had a follow-up score of 0 (47% to 54%), while about a third had a follow-up score of 1 (34% to 38%), and a lower percentage had an increase to a score of 2 (9% to 15%). For participants with baseline second highest FRI score of 2, between 25% and 44% of participants had follow-up FRI scores each of 0, 1, and 2. Similar patterns were observed at the tooth level. These results were consistent with most of the existing, limited literature. Overall, fluorosis severity, which was initially mild to moderate, tended to decline during adolescence and young adulthood. Additional study of how this trend affects esthetic perceptions of fluorosis is warranted.

Abstract
AIMS With the increasing number of patients with prosthetic joints, recommendations for antibiotic prophylaxis (AP) prior to dental procedures to prevent prosthetic joint infections (PJI) have changed. METHODS AND RESULTS This survey evaluated dentists' AP practices for patients with prosthetic joints undergoing dental procedures and their familiarity with the American Dental Association Guidelines (ADA CPG) and American Academy of Orthopaedic Surgeons Appropriate Use Criteria (AAOS AUC). Dentists' attitudes about antibiotic resistance, medical-legal aspects, and adverse effects to using AP were examined. Dentists (n = 574) were familiar (51.2%) with ADA CPG and with the AAOS AUC (25.8%). Familiarity varied according to years since graduation. Female dentists (63.5%) were more likely to be very familiar with the ADA CPG than male dentists (49.5%). Overall, 65.4% of respondents believed that AP is not effective in the prevention of PJI, and 19.4% believed there is enough evidence to support AP. For a healthy patient, 28.9% of dentists would never recommend AP, 44.9% would recommend AP within the first two years since prosthetic joint replacement. CONCLUSIONS Dentists' recommendations for the use of AP varied depending on different factors, including health status of the patient, dental procedure, time elapsed since joint surgery, suggesting that adherence to the ADA CPG and AUC is still challenging.

The transition from amalgam to other restorative materials in the U.S. predoctoral pediatric dentistry clinics. Clin Exp Dent Res 2019; 5:413-419. [PMID: 31452952 PMCID: PMC6704025 DOI: 10.1002/cre2.196] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2019] [Revised: 05/05/2019] [Accepted: 05/06/2019] [Indexed: 12/02/2022] Open
Abstract
Increased concerns about the safety of amalgam restorations in children have resulted in many dental schools emphasizing the teaching of alternative dental materials. This study investigated the current teaching of different dental materials for use in posterior teeth in the United States predoctoral pediatric dentistry programs. In 2011, the authors invited the chairs of the predoctoral pediatric dentistry departments in all accredited dental schools at that time (N = 57) to participate in an internet-based survey. Descriptive statistics were calculated to describe the frequency of using different restorative materials. Regression models were developed to explore the factors related to the use of dental restorations in predoctoral pediatric clinics. Among the 44 dental schools that responded (77% response rate), 74% used amalgam, and 93% used composite in primary posterior teeth. Glass ionomer was used by 61% of the schools in primary posterior teeth. Placing amalgam in primary posterior teeth was associated with programs that treated more 3-5-year-old patients (β = .302, p < .043), whereas the use of glass ionomer was associated with having students serving at off-site satellite dental clinics (β = .015, p < .012). In general, having departments with chairs who had positive attitudes towards Minimal Invasive Dentistry (MID) used composite (β = .091, p < .0001) and glass ionomer (β = 103, p < .0001) more frequently and were less likely to use amalgam (β = -.077, p < .005) in primary posterior teeth. Although teaching MID concepts in predoctoral pediatric clinics in dental schools is increasing, the use of amalgam in posterior primary and permanent teeth is still widely practiced.

BACKGROUND Sugar-sweetened beverages (SSB) are considered a risk factor for obesity. OBJECTIVE The objective of the current study was to investigate associations between the predictors of beverage and energy intakes and mean adequacy ratios (MARs), and the outcome of body mass index (BMI) z scores, in a birth cohort using longitudinal models. DESIGN This was a longitudinal analysis of secondary data. PARTICIPANTS/SETTING Participants in the Iowa Fluoride and Iowa Bone Development Studies with two beverage intake questionnaires completed between ages 2 and 4.7 years or 5 and 8.5 years or one questionnaire between ages 9 and 10.5, 11 and 12.5, 13 and 14.5, or 15 and 17 years (n=720); two food and beverage diaries completed between ages 2 and 4.7 years or 5 and 8.5 years or completion of the Block's Kids' Food Frequency Questionnaires at age 11, 13, 15, or 17 years (n=623); and anthropometric measures at the corresponding age 5-, 9-, 11-, 13-, 15-, or 17-year examination(s). PREDICTORS Mean daily 100% juice, milk, SSB, water/sugar-free beverage, and energy intakes and MARs averaged over ages 2 to 4.7, 5 to 8.5, 9 to 10.5, 11 to 12.5, 13 to 14.5, or 15 to 17 years were predictors. OUTCOME BMI z score was the outcome. STATISTICAL ANALYSES Linear mixed models were fit for each beverage, energy, and MAR variable, with the beverage, energy, or MAR variable as the predictor and BMI z score as the outcome. Beverage models were adjusted for energy and MAR and baseline socioeconomic status. RESULTS SSB intake adjusted for energy intake, MAR, and baseline socioeconomic status was associated with BMI z score; each additional 8 oz SSB consumed/day throughout childhood and adolescence increased the BMI z score an average 0.050 units (95% CI 0.022 to 0.079; P=0.001). Adjusted water/sugar-free beverage intake (0.026 units; 95% CI 0.006 to 0.046; P=0.013) was modestly associated with BMI z score, while 100% juice (-0.001 units; 95% CI -0.059 to 0.057; P=0.97) and milk (0.022 units; 95% CI -0.007 to 0.052; P=0.13) intakes were not associated with BMI z scores. CONCLUSIONS Higher SSB intakes were associated with increased BMI z scores throughout childhood and adolescence in Iowa Fluoride Study participants. Public health initiatives targeting SSB consumption during childhood and adolescence remain relevant.

Fluoride intake and cortical and trabecular bone characteristics in adolescents at age 17: A prospective cohort study. Community Dent Oral Epidemiol 2018; 46:527-534. [PMID: 29962091 PMCID: PMC6237627 DOI: 10.1111/cdoe.12373] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2017] [Accepted: 02/08/2018] [Indexed: 11/28/2022]
Abstract
OBJECTIVE To investigate the associations between period-specific and cumulative fluoride (F) intakes from birth to age 17 years, and radial and tibial bone measures obtained using peripheral quantitative computed tomography (pQCT). METHODS Participants (n = 380) were recruited from hospitals at birth and continued their participation in the ongoing Iowa Fluoride Study/Iowa Bone Development Study until age 17. Fluoride intakes from water, other beverages, selected foods, dietary fluoride supplements and dentifrice were determined every 1.5-6 months using detailed questionnaires. Associations between F intake and bone measures (cortical and trabecular bone mineral content [BMC], density and strength) were determined in bivariate and multivariable analyses adjusted for height, weight, maturity offset, physical activity, and daily calcium and protein intake using robust regression analysis. RESULTS Fluoride intake ranged from 0.7 to 0.8 mg F/d for females and from 0.7 to 0.9 mg F/d for males. Spearman correlations between daily F intake and pQCT bone measures were weak. For females, Spearman correlations ranged from r = -.08 to .21, and for males, they ranged from r = -.03 to .30. In sex-specific, height-, weight- and maturity offset- partially adjusted regression analyses, associations between females' fluoride intake and bone characteristics were almost all negative; associations for males were mostly positive. In the fully adjusted models, which also included physical activity, and protein and calcium intakes, no significant associations were detected for females; significant positive associations were detected between F intake from 14 to 17 years and tibial cortical bone content (β = 21.40, P < .01) and torsion strength (β = 175.06, P < .01) for males. CONCLUSION In this cohort of 17-year-old adolescents, mostly living in optimally fluoridated areas, lifelong F intake from combined sources was weakly associated with bone pQCT measures.

Survival analysis of caries incidence in African-American school-aged children. J Public Health Dent 2018; 79:10-17. [PMID: 30238461 DOI: 10.1111/jphd.12289] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2017] [Revised: 06/09/2018] [Accepted: 08/10/2018] [Indexed: 11/29/2022]
Abstract
OBJECTIVES To conduct an assessment of time-dependent covariates related to dental caries of the permanent dentition among a low socioeconomic status, understudied cohort of children, incorporating time-dependent covariates through the application of extended Cox proportional hazards modeling. METHODS This study modeled the time to first cavitated dental caries in permanent teeth among school-aged children and assessed factors associated with this event. A cohort of 98 low socioeconomic status African-American children with mean age of 5.85 years at baseline was recruited in Uniontown, Alabama and followed prospectively for 6 years. None of these children had dental caries on permanent teeth at baseline, and oral examinations were performed annually. Caries-free survival curves were generated to describe time to event (having first decayed, filled, or missing permanent surface). Bivariate and multivariable extended Cox hazards modeling was used to assess the relationships between time-dependent and time-independent covariates and time to event. RESULTS Twenty-eight children (28.6 percent) had their first permanent tooth caries event during the 6-year follow-up. Multivariable results showed that greater consumption of water was associated with lower dental caries hazard, while previous primary tooth caries experience was associated with greater dental caries hazard after adjustment for frequency of consumptions of milk, added-sugar beverages, and 100 percent juice. CONCLUSIONS There was a global/overall significant caries protective effect of water consumption during the school-age period of child development.

Associations of fluoride intake with children's cortical bone mineral and strength measures at age 11. J Public Health Dent 2018; 78:352-359. [PMID: 30155933 DOI: 10.1111/jphd.12286] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2017] [Revised: 05/31/2018] [Accepted: 06/24/2018] [Indexed: 11/28/2022]
Abstract
OBJECTIVES There is strong affinity between fluoride and calcium, and mineralized tissues. Investigations of fluoride and bone health during childhood and adolescence show inconsistent results. This analysis assessed associations between period-specific and cumulative fluoride intakes from birth to age 11, and age 11 cortical bone measures obtained using peripheral quantitative computed tomography (pQCT) of the radius and tibia (n = 424). METHODS Participants were a cohort recruited from eight Iowa hospitals at birth. Fluoride intakes from water, other beverages, selected foods, dietary supplements, and dentifrice were recorded every 1.5-6 months using detailed questionnaires. Correlations between bone measures (cortical bone mineral content, density, area, and strength) and fluoride intake were determined in bivariate and multivariable analyses adjusting for Tanner stage, weight and height. RESULTS The majority of associations were weak. For boys, only the positive associations between daily fluoride intakes for 0-3 years and radius and tibia bone mineral content were statistically significant. For girls, the negative correlations of recent daily fluoride intake per kg of body weight from 8.5 to 11 years with radius bone mineral content, area, and strength and tibia strength were statistically significant. No associations between cumulative daily fluoride intakes from birth to 11 years and bone measures were statistically significant. CONCLUSIONS In this cohort of 11-year-old children, mostly living in optimally fluoridated areas, life-long fluoride intakes from combined sources were weakly associated with tibia and radius cortical pQCT measures.

Description of Child and Adolescent Beverage and Anthropometric Measures According to Adolescent Beverage Patterns. Nutrients 2018; 10:nu10080958. [PMID: 30044405 PMCID: PMC6115990 DOI: 10.3390/nu10080958] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Revised: 07/13/2018] [Accepted: 07/20/2018] [Indexed: 01/18/2023] Open
Abstract
Our objective is to retrospectively describe longitudinal beverage intakes and anthropometric measures according to adolescent beverage patterns. Data were collected from Iowa Fluoride Study participants (n = 369) using beverage questionnaires at ages 2⁻17 years. Weight and height were measured at ages 5, 9, 13 and 17 years. Cluster analyses were used to identify age 13- to 17-year beverage patterns. Treating age and beverage cluster as explanatory factors, sex-specific generalized linear mixed models were used to identify when differences in beverage intakes and anthropometric measures began. Predominant beverage intakes were higher in each of the corresponding clusters by 9⁻12.5 years; females with high milk intakes during adolescence and males with high 100% juice or sugar-sweetened beverage intakes during adolescence reported higher intakes of that beverage beginning at 2⁻4.7 years. Females and males in the 100% juice cluster had lower weights than other clusters beginning at 13 years, while females and males in the neutral cluster were shorter beginning at 13 years. Females in the water/sugar-free beverage cluster had higher body mass indices (BMIs) beginning at 9 years. Females and males in the 100% juice cluster had lower BMIs beginning at 5 and 9 years, respectively. Childhood beverage intakes and growth patterns differ according to adolescent beverage patterns.

Higher Longitudinal Milk Intakes Are Associated with Increased Height in a Birth Cohort Followed for 17 Years. J Nutr 2018; 148:1144-1149. [PMID: 29924327 PMCID: PMC6669942 DOI: 10.1093/jn/nxy071] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2018] [Accepted: 03/19/2018] [Indexed: 11/14/2022] Open
Abstract
Background Height is an indicator of nutritional status; linear growth faltering has recognized consequences for cognitive, emotional, and chronic disease risk. Although height is routinely studied in developing countries, less attention is given to height in the United States. Objective The objective of this study was to identify longitudinal associations between childhood and adolescent beverage intakes, nutrient adequacy, or energy intake and height in a birth cohort. Methods Data for participants through ages 2-17 y (n = 717; 353 males, 364 females) recruited at birth for the longitudinal Iowa Fluoride Study (IFS) were used in the current cohort analyses. Beverage intakes (n = 708) were collected by beverage-frequency questionnaires at 3- to 6-mo intervals, whereas nutrient data (n = 652) were obtained from 3-d food diaries completed at 3- to 6-mo intervals through age 8.5 y and from Block Kids' food-frequency questionnaires at 2-y intervals after age 8.5 y. Nutrient adequacy ratios were calculated with the use of age- and sex-specific Estimated Average Requirements. Height was measured at clinic visits when the participants were approximately ages 5, 9, 11, 13, 15, and 17 y. Linear mixed models were used to identify longitudinal associations between dietary variables and height. A baseline model that adjusted for changing growth patterns during adolescence was established. Dietary and potential confounding variables were added to this baseline model. Results Milk intake adjusted for mean adequacy ratio, energy intake, and baseline socioeconomic status was associated with height; for each additional 8 ounces (236 mL) of milk consumed per day throughout childhood and adolescence, height increased, on average, by 0.39 cm (95% CI: 0.18, 0.60 cm; P < 0.001). Conclusions IFS participants' height increased by 0.39 cm for each additional 8 ounces (236 mL) of milk consumed throughout childhood and adolescence. The clinical implications of the mild linear growth faltering observed in healthy youth are unknown. This trial was registered at www.clinicaltrials.gov as 199112665.

Abstract
OBJECTIVES To assess longitudinal associations between permanent tooth caries increment and both modifiable and non-modifiable risk factors, using best subsets model selection. METHODS The Iowa Fluoride Study has followed a birth cohort with standardized caries exams without radiographs of the permanent dentition conducted at about ages 9, 13, and 17 years. Questionnaires were sent semi-annually to assess fluoride exposures and intakes, select food and beverage intakes, and tooth brushing frequency. Exposure variables were averaged over ages 7-9, 11-13, and 15-17, reflecting exposure 2 years prior to the caries exam. Longitudinal models were used to relate period-specific averaged exposures and demographic variables to adjusted decayed and filled surface increments (ADJCI) (n = 392). The Akaike Information Criterion (AIC) was used to assess optimal explanatory variable combinations. RESULTS From birth to age 9, 9-13, and 13-17 years, 24, 30, and 55 percent of subjects had positive permanent ADJCI, respectively. Ten models had AIC values within two units of the lowest AIC model and were deemed optimal based on AIC. Younger age, being male, higher mother's education, and higher brushing frequency were associated with lower caries increment in all 10 models, while milk intake was included in 3 of 10 models. Higher milk intakes were slightly associated with lower ADJCI. CONCLUSIONS With the exception of brushing frequency, modifiable risk factors under study were not significantly associated with ADJCI. When possible, researchers should consider presenting multiple models if fit criteria cannot discern among a group of optimal models.

Retrospective analysis of factors associated with the success of stepwise excavation procedure in deep carious lesions. J Am Dent Assoc 2018; 149:442-450.

Abstract
BACKGROUND Recent scientific evidence regarding the stepwise excavation procedure (SWP) has not addressed the consideration of patient factors when selecting SWP as treatment for deep carious lesions (DCLs). This study assessed patient factors predicting a successful SWP defined as a tooth restored with SWP and did not result in root canal treatment or a dental extraction. METHODS SWPs completed in 626 patients without symptomatic irreversible pulpitis at the University of Iowa College of Dentistry from January 2004 through December 2012 were evaluated. Patient demographic and tooth-specific characteristics were assessed in their relationship with the main outcome. RESULTS SWPs had a 75% success rate when evaluated within 36 months of the initial treatment. Findings showed that patients who had successful SWP treatment of DCLs were somewhat younger than patients whose SWP treatment was not successful (mean age, 37.4 years and 40.5 years, respectively; odds ratio, 0.981; 95% confidence interval, 0.967 to 0.994; P = .0058). Patients who returned to their second appointment within 5 to 9 months were more likely to have a successful SWP treatment than those returning sooner than 5 months (odds ratio, 0.338; 95% confidence interval, 0.210 to 0.545; p < .0001). CONCLUSION Treatment of deep carious lesions with SWP is effective for pulp preservation and patient age may influence the outcome. PRACTICAL IMPLICATIONS Although a somewhat younger mean patient age was associated with successful treatment of DCLs, SWP can be successful regardless of patient age and clinicians should consider SWP in treating DCLs.

Evidence of Early Emergence of the Primary Dentition in a Northern Plains American Indian Population. JDR Clin Trans Res 2018; 3:161-169.

Abstract
The purposes of this study were to describe primary tooth emergence in an American Indian (AI) population during the first 36 mo of life to compare 1) patterns of emergence between male and female children and 2) tooth emergence between these AI children and other U.S. ethnic groups. Data were derived from a birth cohort of 239 AI children from a Northern Plains tribe participating in a longitudinal study of early childhood caries, with examination data at target ages of 8, 12, 16, 22, 28, and 36 mo of age (±1 mo). Patterns of emergence in AI children were characterized and sex comparisons accomplished with interval-censored survival methodology. Numbers of erupted teeth in AI children at each age were compared via Kruskal-Wallis tests against those in children of the same age, as drawn from a cross-sectional study of dental caries patterns in Arizona; these comparisons were based on the dental examinations of 547 White non-Hispanic and 677 Hispanic children. Characterization of time to achievement of various milestones-including emergence of the anterior teeth, the first molars, and the complete primary dentition-provided no evidence of sex differences among AI children. AI children had significantly more teeth present at 8 mo (median, 3) than either White non-Hispanic (P < 0.0063) or Hispanic (P < 0.0001) children (median, 2 each). This was also true at 12 mo (P < 0.001; medians, 8 vs. 6 and 7, respectively) and 16 mo (P < 0.001; medians, 12 vs. 11 each). Less pronounced differences were seen at 22 mo (P < 0.0001). White non-Hispanic and Hispanic children did not differ at any time considered (P > 0.05). These results provide evidence of earlier tooth emergence in AI children than in the other 2 ethnicities. Although the underlying etiology of the severity of early childhood caries in AI children is likely to be multifactorial, earlier tooth emergence may be a contributing factor. Knowledge Transfer Statement: The findings of this study have practical implications for practitioners providing childhood oral health care to ethnic groups with early tooth emergence. It may be important to provide parents with information on toothbrushing, dentist visits, and other practices supportive of good oral health as early as possible to protect their children's primary dentition.

Mutans Streptococci and Dental Caries: A New Statistical Modeling Approach. Caries Res 2018; 52:246-252.

Abstract
Survival analyses have been used to overcome some of the limitations encountered with other statistical analyses. Although extended Cox hazard modeling with time-dependent variables has been utilized in several medical studies, it has never been utilized in assessing the complex relationship between mutans streptococci (MS) acquisition (time-dependent covariate) and time to having dental caries (outcome). This study involved secondary analyses of data from a prospective study conducted at the University of Alabama at Birmingham. Low socioeconomic status, African-American preschool children from Perry County, AL, USA (n = 95) had dental examinations at age 1 year and annually thereafter until age 6 years by three calibrated dentists. Salivary MS tests were done at ages 1, 1.5, 2, 2.5, 3, and 4 years. The patterns of and relationship between initial MS detection (time-dependent covariate) and dental caries experience occurrence were assessed, using extended Cox hazard modeling. The median time without MS acquisition (50% of the children not having positive MS test) was 2 years. Approximately 79% of the children had positive salivary MS tests by the age of 4 years. The median caries experience survival (50% of the children not having dental caries) was 4 years. During the follow-up period, 65 of the children (68.4%) had their initial primary caries experience. Results of the extended Cox hazard modeling showed a significant overall/global relationship between initial caries experience event at any given time during the follow-up period and having a positive salivary MS test at any time during the follow-up period (hazard ratio = 2.25, 95% CI 1.06-4.75). In conclusion, the extended Cox modeling was used for the first time and its results showed a significant global/overall relationship between MS acquisition and dental caries. Further research using causal mediation analysis with survival data is necessary, where the mediator "presence of MS" is treated as a time-dependent variable.

Abstract
Early childhood caries is a complex health care issue that has a multifactorial etiology. One aspect of this etiology is the colonization and propagation of acidogenic bacteria at an early age. There have been several bacterial species associated with caries but 1 common species is Streptococcus mutans. Here, we describe genotypic diversity and commonality of Streptococcus mutans recovered from children representing 2 groups with similar socioeconomic demographics: a Northern Plains American Indian Tribe and a Southeast Iowa population. Forty 36‐month‐old American Indian children were selected from a cohort of 239 mothers and children, and forty 2‐ to 5‐year‐old children from Southeast Iowa were selected to compare the genotypic profiles of Streptococcus mutans recovered from each child's plaque. S. mutans isolates were selected from whole mouth plaque samples; DNA was extracted and amplified via AP‐PCR to show specific genotype patterns. These patterns were compared with GelComparIIv6.5 gel analysis software. We found 18 distinct genotypes from 524 isolates; 13 of which were common between the 2 communities. Five genotypes were unique to only the American Indian children while the Southeast Iowa children harbored no unique genotypes. Although the American Indian children had some genotypes that were not present in the Southeast Iowa children, these were not widely distributed among the community. Furthermore, the levels of genotypic diversity and commonality were similar between the 2 populations. This study sets the groundwork for a comprehensive comparison of genotypes and caries among larger subsections of both populations.

Examining caries aetiology in adolescence with structural equation modelling. Community Dent Oral Epidemiol 2017; 46:258-264.

Abstract
OBJECTIVES This analysis examines the aetiology of caries development in adolescents using structural equation modelling to identify behavioural mediators of the relationship between socioeconomic status (SES) and caries incidence, and to investigate the role of sex on caries-preventive behaviour and caries. METHODS This analysis was based on data from the Iowa Fluoride Study, a longitudinal study of a birth cohort. We hypothesized that socioeconomic status earlier in life has a direct effect on caries development and an indirect effect from improved behavioural variables-dental visit attendance, toothbrushing frequency and percentage of beverage intake consisting of sugar-sweetened beverages-and that sex also plays a role in behavioural variables, as well as caries. A structural equation model was developed based on these hypotheses, and direct and indirect standardized path coefficients were calculated, as well as their standard errors. RESULTS Based on our proposed model, SES at birth significantly influences SES during adolescence, but not adolescent behaviours. The effect of SES during adolescence on caries in the permanent dentition is mediated by adolescent behaviours. Female participants have worse caries than male participants, despite lower self-reported percentages of sugar-sweetened beverage intake and more frequent brushing and dental attendance. CONCLUSIONS This analysis models the relationships among known causal factors for caries and suggests that the role of SES in caries may not be as important as previously thought and different behaviours that affect oral health between males and females as well as differences in caries between the sexes could begin during adolescence. These findings could help improve caries prevention programmes for adolescents.

Abstract
OBJECTIVES There have been very few longitudinal studies of dental caries in adolescents, and little study of the caries risk factors in this age group. The purpose of this study was to describe different caries trajectories and associated risk factors among members of the Iowa Fluoride Study (IFS) cohort. METHODS The IFS recruited a birth cohort from 1992 to 1995, and has gathered dietary, fluoride and behavioural data at least twice yearly since recruitment. Examinations for dental caries were completed when participants were ages 5, 9, 13 and 17 years. For this study, only participants with decayed and filled surface (DFS) caries data at ages 9, 13 and 17 were included (N=396). The individual DFS counts at age 13 and the DFS increment from 13 to 17 were used to identify distinct caries trajectories using Ward's hierarchical clustering algorithm. A number of multinomial logistic regression models were developed to predict trajectory membership, using longitudinal dietary, fluoride and demographic/behavioural data from 9 to 17 years. Model selection was based on the akaike information criterion (AIC). RESULTS Several different trajectory schemes were considered, and a three-trajectory scheme-no DFS at age 17 (n=142), low DFS (n=145) and high DFS (n=109)-was chosen to balance sample sizes and interpretability. The model selection process resulted in use of an arithmetic average for dietary variables across the period from 9 to 17 years. The multinomial logistic regression model with the best fit included the variables maternal education level, 100% juice consumption, brushing frequency and sex. Other favoured models also included water and milk consumption and home water fluoride concentration. The high caries cluster was most consistently associated with lower maternal education level, lower 100% juice consumption, lower brushing frequency and being female. CONCLUSIONS The use of a clustering algorithm and use of Akaike's Information Criterion (AIC) to determine the best representation of the data were useful means in presenting longitudinal caries data. Findings suggest that high caries incidence in adolescence is associated with lower maternal educational level, less frequent tooth brushing, lower 100% juice consumption and being female.

Abstract
Crowns and large amalgams protect structurally compromised teeth to various degrees in different situations. The aim of this investigation was to evaluate the survival of teeth with these two types of restorations and the factors associated with better outcomes. Retrospective administrative and chart data were used. Survival was defined and modeled as: (1) receipt of no treatment and (2) receipt of no catastrophic treatment over five- and 10-year periods. Analyses included: Kaplan-Meier survival curves, Log-Rank tests, and Cox proportional hazards regression modeling. Crowns survived longer with no treatment and with no catastrophic treatment; however, mandibular large amalgams were least likely to have survived with no treatment, and maxillary large amalgams were least likely to have survived with no catastrophic treatment. Having no adjacent teeth also decreased survival. Crowns survived longer than large amalgams, but factors such as arch type and the presence of adjacent teeth contributed to the survival of large amalgams.

A novel staging system for caries severity in the primary dentition. J Public Health Dent 2016; 77:6-12. [PMID: 27307188 DOI: 10.1111/jphd.12164] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2015] [Accepted: 04/15/2016] [Indexed: 11/28/2022]
Abstract
OBJECTIVES Caries in the primary dentition (CIPD) has a high prevalence in U.S. children compared to other diseases, with substantial disparities among different population groups. Few reports correlate CIPD prevalence with clinical impairment of children's quality of life, such as tooth pain, speech delay or trauma to the child from operative restorations, which we collectively term morbidity. Likewise, current case definitions (ECC, S-ECC) and disease metrics (mean dmfs/dmft) are not helpful in assessing morbidity for individual or groups of children. We describe a construct to stage caries severity for children ages 0 -5, called "CIPD Levels." This metric is based on small interval age-group dmft scores, and has a direct link to current and predicted morbidity for the child. It is modeled after staging systems for medical diseases in which the various stages or levels are correlated with the probability of morbidity or mortality. METHODS We created a matrix in which CIPD Levels 0-4 are assigned for dmft scores 0-7 depending on a child's age. CIPD Level-4 is the highest level, and frequently results in clinical adverse outcomes, including pain and extensive restorations. We next tested this matrix with data from a high-risk population. RESULTS Among children with any cavitated caries at age <24 months, 82.8% reached the adverse outcomes threshold (CIPD Level-4) at age 36 months. For children with dmft = 0 at 24 months, 71.4% did not reach CIPD Level-4 at age 36 months. CONCLUSION Our new metric is useful for quantifying disease burden from caries for high-risk children.

Understanding Pediatric Dentists' Dental Caries Management Treatment Decisions: A Conjoint Experiment. JDR Clin Trans Res 2016; 1:86-94.

Abstract
When traditional ranking and rating surveys are used to assess dentists' treatment decisions, the patient's source of payment appears to be of little importance. Therefore, this study used the marketing research tool conjoint analysis to investigate the relative impact of source of payment along with the child's age and cooperativeness on pediatric dentists' willingness to use Atraumatic Restorative Treatment (ART) to restore posterior primary teeth. A conjoint survey was completed by 707 pediatric dentists. Three factors (age of the child, cooperativeness, type of insurance) were varied across 3 levels to create 9 patient scenarios. The relative weights that dentists placed on these factors in the restorative treatment decision process were determined by conjoint analysis. "Cooperativeness" (52%) was the most important factor, "age of the child" (26%) the second-most important factor, followed by "insurance status of the child" (22%). For the third factor, insurance, pediatric dentists were least willing to use ART with publicly insured children (-0.082), and this was significantly different from their willingness to use ART with uninsured children (0.010) but not significantly different than their willingness to use ART for children with private insurance (0.073). Unlike traditional ranking and rating tools, conjoint analysis found that the insurance status of the patient appeared to be an important factor in dentists' decisions about different restorative treatment options. When pediatric dentists were forced to make tradeoffs among different patients' factors, they were most willing to use ART technique with young, uncooperative patients when they had no insurance. Knowledge Transfer Statement: The present study suggests the feasibility of using techniques borrowed from marketing research, such as conjoint analysis, to understand dentists' restorative treatment decisions. Results of this study demonstrate pediatric dentists' willingness to use a particular restorative treatment option (Atraumatic Restorative Treatment in this application) when forced to make tradeoffs in a "conjoined," or holistic, context among different factors presented in real-life patient scenarios. A deeper understanding of dentists' treatment decisions is vital to develop valid practice guidelines and interventions that encourage the use of appropriate restorative treatment modalities.

Abstract
OBJECTIVES To compare timing of tooth emergence among groups of American Indian (AI), Black and White children in the United States at 12 months of age. METHODS Data were from two sources - a longitudinal study of a Northern Plains tribal community and a study with sites in Indiana, Iowa and North Carolina. For the Northern Plains study, all children (n = 223) were American Indian, while for the multisite study, children (n = 320) were from diverse racial groups. Analyses were limited to data from examinations conducted within 30 days of the child's first birthday. RESULTS AI children had significantly more teeth present (Mean: 7.8, Median: 8.0) than did Whites (4.4, 4.0, P < 0.001) or Blacks (4.5, 4.0, P < 0.001). No significant differences were detected between Black and White children (P = 0.58). There was no significant sex difference overall or within any of the racial groups. CONCLUSIONS Tooth emergence occurs at a younger age for AI children than it does for contemporary White or Black children in the United States.

Abstract
PURPOSE The purpose of this study was to assess the prevalence and incidence of dental caries in school-age African American children who received semi-annual fluoride varnish applications. METHODS A cohort of six-year-old high caries-risk African American children (n equals 98) was recruited in Uniontown, Ala., USA, and followed for six years. Oral examinations were done annually by three trained/calibrated dentists. Tooth surfaces with cavitated caries, teeth missing due to caries, and teeth with filled surfaces were recorded using World Health Organization criteria. Also, as part of the study, children received periodic oral health instruction, fluoride varnish applications, and referrals to dentists starting at baseline. RESULTS The person-level prevalence of decayed, missing, and filled surfaces of primary and permanent teeth (dmfs/DMFS) was: 61.2 percent at mean age of 5.9 years old (n equals 98, mean dmfs/DMFS equals 11.6); 63.8 percent at 6.7 years old (n equals 80, mean dmfs/ DMFS equals 13.2); 70.6 percent at 7.8 years old (n equals 68, mean dmfs/DMFS equals 14.2); 65.7 percent at 8.8 years old (n equals 68, mean dmfs/DMFS equals 11.8); 55.6 percent at 9.7 years old (n equals 63, mean dmfs/DMFS equals 8.8); 40.3 percent at 10.7 years old (n equals 62, mean dmfs/DMFS equals 3.4); and 37.1 percent at 11.7 years old (n equals 62, mean dmfs/DMFS equals 2.3). The six-year person-level incidence of dmfs/DMFS was 32.3 percent (mean dmfs/DMFS equals 1.6) from 5.9 to 11.7 years old (<small>N</small> equals 62). CONCLUSIONS In spite of the oral health education and fluoride varnish applications, there was substantial new dental caries in this high-risk sample. Additional studies evaluating risk factors for caries development are ongoing.

Abstract
PURPOSE Little is known about use or acceptance of minimally invasive dentistry (MID) in the USA, particularly in public health settings. The purpose of this study was to assess opinions concerning MID among dentists in public-health practices. MATERIALS AND METHODS A cross-sectional study was conducted to assess the views of dentists in public-health practices concerning MID using an online survey instrument among National Network for Oral Health Access (NNOHA) and American Association of Community Dental Programs (AACDP) members. Specific questions focused on diagnostic and preventive techniques, and whether MID was considered to meet the standard of care in the US Results: Overall, 86% believed that MID met the standard of care for primary teeth, and 77% did so for permanent teeth. The majority of respondents also agreed that fluoride varnish prevents caries and atraumatic restorative techniques (ART) are an effective caries treatment for children and adults. According to logistic regression results, dentists who had continuing education courses in MID and agreed that ART was an effective treatment for adults were more likely to report that MID met the standard of care for permanent teeth. Subjects who believed that fluoride varnish was effective as caries prevention for children were more likely to view MID as meeting the standard of care for primary teeth. CONCLUSIONS There appears to be a paradigm shift toward a MID philosophy, and most responding public health dentists believed that MID meets the standard of care for primary and permanent teeth in the US.

Abstract
OBJECTIVES Early childhood caries (ECC) is rampant among American Indian children, but there has been relatively little study of this problem. This article reports on risk factors for caries for a group of American Indian children at age 36 months as part of a longitudinal study. METHODS Pregnant women from a Northern Plains Tribal community were recruited to participate in a longitudinal study of caries and caries risk factors. Standardized dental examinations were completed on children, and questionnaires were completed by mothers at baseline and when children were 4, 8, 12, 16, 22, 28, and 36 months of age. Examinations were surface-specific for dental caries, and the questionnaires collected data on demographic, dietary, and behavioral factors. Nonparametric bivariate tests and logistic regression models were used to identify risk factors for caries at 36 months, and negative binomial regression was used to identify factors related to caries severity (dmf counts). RESULTS Among the 232 children, and caries prevalence for cavitated lesions was 80%, with an additional 15% having only noncavitated lesions. The mean dmfs was 9.6, and of the total dmfs, nearly 62% of affected surfaces were decayed, 31% were missing, and 7% were filled. Logistic regression identified higher added-sugar beverage consumption, younger maternal age at baseline, higher maternal DMFS at baseline, and greater number of people in the household as significant (P < 0.05) risk factors. Negative binomial regression found that only maternal DMFS was associated with child dmf counts. CONCLUSIONS By the age of 36 months, dental caries is nearly universal in this population of American Indian children. Caries risk factors included sugared beverage consumption, greater household size, and maternal factors, but further analyses are needed to better understand caries in this population.

Abstract
BACKGROUND This study evaluated service-learning programme's impact on senior dental students' attitude towards community service at Virginia Commonwealth University (VCU) School of Dentistry. Experience gained through service-learning in dental school may positively impact dental students' attitude towards community service that will eventually lead into providing care to the underserved. MATERIALS AND METHODS Two surveys (pre- and post-test) were administered to 105 senior dental students. For the first survey (post-test), seventy-six students of 105 responded and reported their attitude towards community service immediately after the service-learning programme completion. Three weeks later, 56 students of the 76 responded to the second survey (retrospective pre-test) and reported their recalled attitude prior to the programme retrospectively. RESULTS A repeated-measure mixed-model analysis indicated that overall there was improvement between pre-test and post-test. Scales of connectedness, normative helping behaviour, benefits, career benefits and intention showed a significant pre-test and post-test difference. An association between attitude towards community service and student characteristics such as age, gender, ethnicity and volunteer activity was also examined. Only ethnicity showed an overall significant difference. White dental students appear to have a differing perception of the costs of community service. CONCLUSIONS The service-learning programme at VCU School of Dentistry has positively impacted senior dental students' attitude towards community service.

Timing of fluoride intake and dental fluorosis on late-erupting permanent teeth. Community Dent Oral Epidemiol 2015.

Abstract
OBJECTIVE Very few studies have examined the relationship between timing of fluoride intake and development of dental fluorosis on late-erupting permanent teeth using period-specific fluoride intake information. This study examined this relationship using longitudinal fluoride intake information from the Iowa Fluoride Study. METHODS Participants' fluoride exposure and intake (birth to 10 years of age) from water, beverages, selected food products, dietary fluoride supplements, and fluoride toothpaste was collected using questionnaires sent to parents at 3- and 4- month intervals from birth to 48 months of age and every 6 months thereafter. Three trained and calibrated examiners used the Fluorosis Risk Index (FRI) categories to assess 16 late-erupting teeth among 465 study participants. A tooth was defined as having definitive fluorosis if any of the zones on that tooth had an FRI score of 2 or 3. Participants with questionable fluorosis were excluded from analyses. Descriptive and logistic regression analyses were performed to assess the importance of fluoride intake during different time periods. RESULTS Most dental fluorosis in the study population was mild, with only four subjects (1%) having severe fluorosis (FRI Score 3). The overall prevalence of dental fluorosis was 27.8%. Logistic regression analyses showed that fluoride intake from each of the individual years from age 2 to 8 plays an important role in determining the risk of dental fluorosis for most late-erupting permanent teeth. The strongest association for fluorosis on the late-erupting permanent teeth was with fluoride intake during the sixth year of life. CONCLUSION Late-erupting teeth may be susceptible to fluorosis for an extended period from about age 2 to 8. Although not as visually prominent as the maxillary central incisors, some of the late-erupting teeth are esthetically important and this should be taken into consideration when making recommendations about dosing of fluoride intake.

Abstract
OBJECTIVES To summarize diagnostic criteria and examiner training and calibration of the National Institute of Dental and Craniofacial Research-funded Early Childhood Caries Collaborating Centers (EC4) and report examiner calibration results from 2010 to 2014. The EC4 at Boston University, University of Colorado, and University of California San Francisco are performing randomized controlled early childhood caries (ECC) prevention trials with caries as the main outcome measure. METHODS The EC4 with University of Iowa consultants developed standardized tooth and tooth surface status examination criteria for use in field conditions, examiner training materials, and examiner calibration and re-calibration methodologies. Calibration and re-calibration were performed with 1- to 5-year-old children in the San Francisco Mission District in which assessments from each examiner to be calibrated were compared with those from a single gold standard examiner from 2010 to 2014. Cohen's kappa statistic was used to determine inter-examiner agreement. RESULTS A total of seven examiners were successfully (re)calibrated during that period, examining a total of 231 children. Overall unweighted Cohen's kappas for 10 surface conditions exceeded the criterion of 0.70. However, separate agreement for assessment of noncavitated lesions, as in other studies, was lower. CONCLUSIONS An experienced multidisciplinary and multi-institutional team was able to develop criteria and training materials to anticipate situations and field conditions the main trials would encounter. Examiners were successfully trained and (re)calibrated.

Abstract
Background Severe-early childhood caries (S-ECC) is one of the most common infectious diseases in children and is prevalent in lower socio-economic populations. American Indian children suffer from the highest levels of S-ECC in the United States. Members of the mutans streptococci, Streptococcus mutans, in particular, are key etiologic agents in the development of caries. Children typically acquire S. mutans from their mothers and early acquisition is often associated with higher levels of tooth decay. Methods We have conducted a 5-year birth cohort study with a Northern Plains Tribe to determine the temporality and fidelity of S. mutans transmission from mother to child in addition to the genotypic diversity of S. mutans in this community. Plaque samples were collected from 239 mother/child dyads at regular intervals from birth to 36 months and S. mutans were isolated and genotyped by arbitrarily primed-polymerase chain reaction (AP-PCR). Results Here we present preliminary findings from a subset of the cohort. The focus for this paper is on initial acquisition events in the children. We identified 17 unique genotypes in 711 S. mutans isolates in our subset of 40 children, 40 mothers and 14 primary caregivers. Twelve of these genotypes were identified in more than one individual. S. mutans colonization occurred by 16 months in 57.5% of the children and early colonization was associated with higher decayed, missing and filled surface (DMFS) scores (p=0.0007). Children colonized by S. mutans shared a common genotype with their mothers 47.8% of the time. While multiple genotypes were common in adults, only 10% of children harbored multiple genotypes. Conclusion These children acquire S. mutans at an earlier age than the originally described ‘window of infectivity’ and often, but not exclusively, from their mothers. Early acquisition is associated with both the caries status of the children and the mothers.

Abstract
PURPOSE This study's purpose was to assess the association between infant breast-feeding and caries experience of primary second molars in a nine-year longitudinal cohort study. METHODS Study sample was 509 subjects recruited at birth. Information about breast-feeding duration and other factors was collected through parents' responses to periodic questionnaires. Primary teeth were examined for dental caries at five years old and nine years old by calibrated dentist examiners. Caries experience (yes/no) and number of decayed and/or filled surfaces (dfs) were determined for five- and nine-year-olds. RESULTS For primary second molars at five years old, 18 percent of children who were breast-fed less than six months had caries (mean dfs=0.55) while only 9 percent of children who were breast-fed at least six months had caries (mean dfs=0.33). From five to nine years old, caries incidence was 32 percent and 31 percent, respectively, for children breast-fed less than six months and at least six months. In multivariable regression analyses, shorter breast-feeding duration was positively associated with caries experience of primary second molars at five years old (P=.005), both before and after controlling for other important factors. CONCLUSIONS Shorter duration of breast-feeding is suggested to be associated with increased risk for early childhood caries, but its impact might diminish with age.

Abstract
Much progress has been made in the science of caries risk assessment and ways to analyze caries risk, yet dental education has seen little movement toward the development of frameworks to guide learning and assess critical thinking in caries risk assessment. In the absence of previous proactive implementation of a learning framework that takes the knowledge of caries risk and critically applies it to the patient with the succinctness demanded in the clinical setting, the purpose of this study was to develop a model learning framework that combines the science of caries risk assessment with principles of critical thinking from the education literature. This article also describes the implementation of that model at one dental school and presents some preliminary assessment data.

Abstract
Controversy persists concerning the impact of community water fluoridation on bone health in adults, and few studies have assessed relationships with bone at younger ages. Ecological studies of fluoride's effects showed some increase in bone mineral density of adolescents and young adults in areas with fluoridated water compared with non-fluoridated areas. However, none had individual fluoride exposure measures. To avoid ecological fallacy and reduce bias, we assessed associations of average daily fluoride intake from birth to age 15 yr for Iowa Bone Development Study cohort members with age 15 yr dual-energy x-ray absorptiometry (DXA) bone outcomes (whole body, lumbar spine, and hip), controlling for known determinants (including daily calcium intake, average daily time spent in moderate-to-vigorous intensity physical activity, and physical maturity). Mean (SD) daily fluoride intake was 0.66 mg (0.24) for females and 0.78 mg (0.30) for males. We found no significant relationships between daily fluoride intake and adolescents' bone measures in adjusted models (for 183 females, all p values ≥ .10 and all partial R(2) ≤ 0.02; for 175 males, all p values ≥ .34 and all partial R(2) ≤ 0.01). The findings suggest that fluoride exposures at the typical levels for most US adolescents in fluoridated areas do not have significant effects on bone mineral measures.

Abstract
The International Dental Federation and World Health Organization have promoted the use of Atraumatic Restorative Treatment (ART) in modern clinical settings worldwide. In the United States, the practice of ART is not believed to be widely used, which may be a result of little attention given to ART training in predoctoral pediatric dentistry curricula in U.S. dental schools. This study investigated the extent of clinical and didactic instruction on ART provided in U.S. dental schools by surveying the predoctoral pediatric dentistry programs in 2010. Of the fifty-seven directors asked to complete the survey, forty-four responded for a response rate of 77 percent. Of these forty-four programs, 66 percent reported providing clinical training on ART, though only 14 percent provide this training often or very often. The types of ART training provided often or very often included interim treatment (18 percent) and single-surface cavities (14 percent) in primary teeth. However, ART was said to be rarely taught as a definitive treatment in permanent teeth (2 percent). Attitude was a major predictor, for clinical training provided and using professional guidelines in treatment decisions were associated with a positive attitude towards ART. These predoctoral pediatric dentistry programs used ART mainly in primary, anterior, and single-surface cavities and as interim treatment. As ART increases access of children to dental care, the incorporation of the ART approach into the curricula of U.S. dental schools should be facilitated by professional organizations.

Abstract
PURPOSE The purpose was to compare whether mothers exposed to an autonomy-supportive psychoeducational videotaped message, informed by the self-determination theory (SDT), demonstrated greater changes in oral health knowledge and behavioral intentions as a preventive means for early childhood caries (ECC) than mothers exposed to a neutral message delivered by brochure. METHODS Data were collected at baseline, one-, and six-month follow-ups from 415 12- to 49-month-old WIC-enrolled children and their mothers: 283 in the video intervention group and 132 in the brochure control group. Mothers completed questionnaires on maternal knowledge and behavioral intentions for oral health care. Chi-square, Wilcoxon rank-sum, and Mann-Whitney tests were used to analyze data (P<.05). RESULTS Relative to their baseline scores, the intervention group showed a greater increase in knowledge than the control group, both at one-month (P=.002) and six-month follow-ups (P<.001). The video group also demonstrated a greater increase in behavioral intentions than controls, both at one-month (P<.05) and six-month follow-ups (P<.001). Knowledge and behavioral intention levels at six-month follow-up did not differ significantly from those at one-month follow-up, indicating that intervention-based increases in these measures were maintained over time. CONCLUSIONS Data provided evidence of the effectiveness of the autonomy-supportive psychoeducational intervention for ECC prevention relative to a neutral brochure.

Abstract
PURPOSE The purpose was to compare whether mothers exposed to an autonomy-supportive psychoeducational videotaped message, informed by self-determination theory (SDT), demonstrated greater changes in behavior concerning their children's oral health than mothers exposed to a neutral message delivered by brochure. METHODS Data were collected at baseline, one- and six-month follow-ups from 415 12- to 49-month-old WIC-enrolled children and their mothers: 283 in the video intervention group and 132 in the brochure control group. Mothers completed questionnaires regarding their child's dietary/oral hygiene habits. Chi-square, Wilcoxon Signed Rank, Mann-Whitney, and McNemar tests were used to analyze data (P<0.05). RESULTS Significantly more positive changes were observed for dietary/oral hygiene behaviors among the intervention group mothers at one- and six-month follow-ups than for the controls. Significantly fewer mothers in the intervention group shared dining ware with their child at both one- (P=0.0046) and six-month follow-ups (P<0.0001); this practice was decreased only at six-months for the control group mothers (P=0.05). Restricting consideration only to mothers who were not checking for white spot lesions at baseline, a significantly greater proportion of mothers in the intervention group performed this behavior at six-months (P=0.0044). CONCLUSIONS Data provided evidence of the effectiveness of the SDT videotaped oral health message relative to a neutral brochure.

The associations between dietary intakes from 36 to 60 months of age and primary dentition non-cavitated caries and cavitated caries. J Public Health Dent 2012; 75:265-73. [PMID: 23134446 DOI: 10.1111/j.1752-7325.2012.00376.x] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2011] [Accepted: 09/25/2012] [Indexed: 11/26/2022]
Abstract
OBJECTIVE To examine risk factors for non-cavitated caries, as well as cavitated caries. METHODS Subjects were participants in the Iowa Fluoride Study cohort. Dietary data were collected at 36, 48, and 60 months old using 3-day dietary diaries, and a dental examination was conducted at about age 5. We compared the frequencies of dietary intakes of three groups: a) children having only d1 caries (n = 41); b) children having only cavitated (d2+f) caries (n = 46); and c) children having both d1 and d2+f caries (n = 49) with a forth group; d) those of caries-free children (n = 257). RESULTS Multinomial and binomial logistic regression was used, where the categorical outcome was based on the 4 caries groups, and the caries-free group was designated as the reference. In the final model, sevenvariables were associated with the caries outcome. Lower milk consumption frequency at meals and greater presweetened cereal consumption frequency at meals were significantly associated with a greater likelihood of being in the d1 group. Greater regular soda pop consumption frequency and greater added sugar consumption frequency at snacks were significantly associated with being in the cavitated caries (d2+f and/or d1 d2+f) groups. Lower socioeconomic status and less frequent toothbrushing increased the likelihood of being in the d1 group. CONCLUSIONS The results suggest that different food and beverage categories are associated with being in the d1 group compared with the cavitated caries groups. More frequent toothbrushing, greater milk consumption at meals, and avoiding presweetened cereal consumption at meals might reduce the risk of developing non-cavitated caries.

Abstract
OBJECTIVES This paper reports the prevalence and severity of caries in a group of 16-month-old American Indian children. METHODS The study is an ongoing longitudinal study of risk factors for caries in children from a Northern Plains Tribal community. Children were examined for caries and risk factor data collected at approximately 1, 4, 8, 12, and 16 months of age. Surface-specific caries data were collected and the presence of precavitated "white spot" lesions was recorded at the subject level. RESULTS The mean age was 15.4 months for the sample of 232 children. Caries prevalence was 31.9 percent, while an additional 29.3 percent had white spot lesions only. Mean dmfs was 1.57, and ranged from 0 to 44 surfaces. Nearly 3 percent of all erupted tooth surfaces were affected and maxillary central incisors had the highest prevalence of caries (22 percent). CONCLUSIONS Among the very youngest children, dental caries prevalence was very high among these American Indian children.

Abstract
OBJECTIVES We sought to understand the role of Latino acculturation in dental care utilization in Iowa children. METHODS We used logistic regression to evaluate factors associated with having a previous-year dental check-up with 2005 Iowa Child and Family Household Health Survey data. We constructed models to examine the association with race/ethnicity and used chosen interview language to measure Latino acculturation. RESULTS After we controlled for several factors, having a regular dental care source, having a dental need, dental insurance status, family income, children's dental health rating, children's age, and brushing habits were associated with having a previous-year dental check-up. Race/ethnicity was indirectly associated with use of dental services through other related factors with significant differences for less-acculturated Latinos. CONCLUSIONS Policymakers and health planners should implement strategies to address individual, community, and system factors affecting racial/ethnic minorities. A regular source of dental care for Latino children that will enhance their access to services should be ensured. Ignoring the needs of the fastest growing segment of children with the poorest oral health and the least access to care will lead to future increase of oral diseases in this population.
