Predictors of survival of large non-occlusal non-incisal glass-ionomer restorations in older adults. SPECIAL CARE IN DENTISTRY 2024; 44:1228-1235. [PMID: 38449290 DOI: 10.1111/scd.12981] [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: 12/15/2023] [Revised: 02/09/2024] [Accepted: 02/10/2024] [Indexed: 03/08/2024]
Abstract
PURPOSE This study aimed to investigate the predictors of survival of non-occlusal non-incisal glass-ionomer restorations as a surrogate for root surface restorations among older adults. METHODS In a retrospective cohort analysis using the University of Iowa College of Dentistry electronic dental records, we included 721 patients aged 65+ who received 2+ surface non-occlusal non-incisal glass ionomer restorations placed from January 2005 - December 2011. Restorations were followed until September 2017 or until they were deemed to have failed. RESULTS At baseline, participants' mean age was 77.6 ± 8.2 years, and 45.8% were females. Most patients were self-pay (65.2%). Most restorations were placed by residents and dental students (82.7%) and included only two surfaces (95.6%). About half (49.1%) failed during follow-up, with a median survival time of 3.7 years. The time ratio for lower incisors compared to other teeth was 0.6 (p = .006), for three-and-four-surface restorations compared to two was 0.7 (p = .007), for faculty as providers compared to residents and students was 1.4 (p = .039), and for the Geriatric & Special Needs Clinic compared to others was 0.8 (p = .013). Time ratios less than one indicate association with shorter durations for restorations, and time ratios greater than one indicate association with longer durations for restorations. CONCLUSION Tooth type, number of restored surfaces, provider type, and clinic were all significant factors associated with survival of these restorations.

Detecting white spot lesions on post-orthodontic oral photographs using deep learning based on the YOLOv5x algorithm: a pilot study. BMC Oral Health 2024; 24:490. [PMID: 38658959 PMCID: PMC11044306 DOI: 10.1186/s12903-024-04262-1] [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: 10/10/2023] [Accepted: 04/15/2024] [Indexed: 04/26/2024] Open
Abstract
BACKGROUND Deep learning model trained on a large image dataset, can be used to detect and discriminate targets with similar but not identical appearances. The aim of this study is to evaluate the post-training performance of the CNN-based YOLOv5x algorithm in the detection of white spot lesions in post-orthodontic oral photographs using the limited data available and to make a preliminary study for fully automated models that can be clinically integrated in the future. METHODS A total of 435 images in JPG format were uploaded into the CranioCatch labeling software and labeled white spot lesions. The labeled images were resized to 640 × 320 while maintaining their aspect ratio before model training. The labeled images were randomly divided into three groups (Training:349 images (1589 labels), Validation:43 images (181 labels), Test:43 images (215 labels)). YOLOv5x algorithm was used to perform deep learning. The segmentation performance of the tested model was visualized and analyzed using ROC analysis and a confusion matrix. True Positive (TP), False Positive (FP), and False Negative (FN) values were determined. RESULTS Among the test group images, there were 133 TPs, 36 FPs, and 82 FNs. The model's performance metrics include precision, recall, and F1 score values of detecting white spot lesions were 0.786, 0.618, and 0.692. The AUC value obtained from the ROC analysis was 0.712. The mAP value obtained from the Precision-Recall curve graph was 0.425. CONCLUSIONS The model's accuracy and sensitivity in detecting white spot lesions remained lower than expected for practical application, but is a promising and acceptable detection rate compared to previous study. The current study provides a preliminary insight to further improved by increasing the dataset for training, and applying modifications to the deep learning algorithm. CLINICAL REVELANCE Deep learning systems can help clinicians to distinguish white spot lesions that may be missed during visual inspection.

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.

The value of bitewing radiographs in the management of carious primary molars. Br Dent J 2021; 231:575-579. [PMID: 34773029 DOI: 10.1038/s41415-021-3570-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Accepted: 01/14/2021] [Indexed: 11/09/2022]
Abstract
Introduction Bitewing radiographs (BWs) are under-utilised for children, and reliance on visual diagnosis alone is likely to under-diagnose caries. Quantification of the level of the under-reporting of caries and the vital role of BWs would be beneficial when providing dental care to the paediatric population.Aim To quantify the diagnostic value of bitewings in the management of proximal caries in primary molars.Design Cross-sectional study.Materials and methods Thirty children (mean age 6.2 ± 1.3 years) were recruited. A visual inspection (VI) of the primary molars was carried out and bitewings were taken. Radiographic assessment (RA) for primary molar proximal caries was completed separately. VI and RA were compared statistically against three caries thresholds, using the Fisher's exact test. A p value <0.05 was considered statistically significant. Sensitivity and specificity analyses were performed.Results A total of 480 proximal surfaces were assessed. Bitewings detected 44.6% of additional proximal carious lesions (p <0.0001). At d3 threshold, VI under-reported 51.2% proximal caries (p <0.0001) and 34.1% dentinal proximal caries (p = 0.0012). VI showed high specificity (99%) and low sensitivity (53%).Conclusion Bitewings play a vital role in proximal caries diagnoses of primary molars.

Prevalence of Dental Caries and Periodontal Disease of High School Students Aged 15 to 18 Years in Taiwan. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18199967. [PMID: 34639272 PMCID: PMC8508362 DOI: 10.3390/ijerph18199967] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 09/17/2021] [Accepted: 09/21/2021] [Indexed: 11/17/2022]
Abstract
The purpose of this study was to assess the prevalence and distribution of dental caries and periodontal disease in Taiwanese high school students aged 15–18. A total of 1069 Taiwanese students participated in a cross-sectional nationwide dental survey. By using a stratified method based on the National Health Insurance administration regions, 24 high schools were randomly sampled in different areas of Taiwan. The participants were examined with dental mirrors and community periodontal index (CPI) probes without using radiographs, to measure dental caries and periodontal status. Demographic information and other relevant risk indicators for the two diseases were gathered via a self-report questionnaire. In this study population, the weighted mean decayed, missing and filled teeth (DMFT) scores for ages 15 to 18 were 5.2, 6.1, 6.1, and 5.7. The weighted mean decayed, missing and filled surfaces (DMFS) scores were 9.0, 12.0, 13.1, and 11.2 at ages 15, 16, 17, and 18, respectively. Additionally, 88.2% of the subjects had periodontal disease, with calculus as the most prevalent type. Moreover, 5.2% of these students showed loss of attachment. There was no significant association between dental caries and periodontal disease. Dental caries and periodontal disease were prevalent among Taiwanese high school students in this national dental survey.

Abstract
BACKGROUND To correlate fluorescence-based camera (FC), visual inspection (ICDAS-II) and radiographic examination X-rays bitewings (BW) to the extent of caries after excavation. METHODS The occlusal sites of 20 permanent first and second molars in 14 young adolescents (12±2 years old) were examined at 1st Observation Unit of Department of Oral and Maxillofacial Sciences, "Sapienza" University of Rome. All the enrolled patients were asked to provide with X-rays bitewing of the studied teeth. The assessment of ICDAS-II and FC was performed by a trained operator. Then a second blind operator removed the carious lesion and evaluated the cavity extent (depth, width, length) after caries removal with a calibrated probe. To correlate FC measurements with bitewing sensitivity, 10 dentists evaluated the presence/absence of caries on the X-rays. RESULTS All the occlusal sites assessed by fluorescence camera, ranged from 1.7 to 2, indicating in all cases deep enamel lesions with possible extent to dentine with a mean of 1.7±0. In accordance, visual inspection by ICDAS-II showed scores of 3 and 4. By contrast, the radiographic documentation, i.e. bitewing X-rays, was evaluated in only 6 cases as presence of caries. The extent of the cavities was determined by three consecutive measurements: depth, width and length, with a mean of 3.5+1.73, 2.8+1.07 and 3.2+1.64 mm respectively. These results confirmed the agreement between FC and ICDAS-II for diagnosis of cavities with extent to enamel and dentine, while showed the low sensitivity of bitewings X-rays, in accordance with the existing evidence in Literature. Moreover, the results of this study for the first time provide information about the cavity extent after caries removal for the occlusal sites with ICDAS-II 3 and 4 scores and FC≥1.7. CONCLUSIONS X-rays evaluation showed diagnostic accuracy in 6% of the sample. VistaCam measurement of 1.7 was correlated to a cavity with 3.5, 2.8 and 3.2 mm of depth, width and length.

Abstract
OBJECTIVES (i) To develop, validate, and apply in practice a new risk assessment tool for erosive tooth wear (ETW) including a risk factors questionnaire and a saliva secretion evaluation, which combined with a clinical index, can be part of an ETW composite scoring system; (ii) to assess ETW lesions and current and past erosive challenges in younger age groups. METHODS The Tooth Surface Loss/Erosion Working Group of the European Association of Dental Public Health consisted of an international panel of experts designed the survey component of the new tool (Erosive Wear Assessment of Risk-EWAR) and confirmed its construct and content validity. After receiving ethical approvals and informed consents, the EWAR tool (questionnaire + saliva secretion evaluation) was applied in a multicenter cross-sectional study with 207 participants aged 15-21 years old from four countries (Finland, Greece, Romania, the USA). BEWE score was used for the clinical assessment of ETW. RESULTS A total of 58.5% of participants had ETW. 10.9% and 20.3% of participants had low secretion of stimulated (< 1 ml/min) and unstimulated saliva (< 0.25 ml/min), respectively. The following factors were bivariately significantly associated with ETW: energy drink consumption, low secretion of stimulated saliva, juices consumption, erosive drink consumption for quenching thirst between meals, erosive drink kept in the mouth, feeling pain/icing after consuming something acidic or cold, and co-existence of other type of tooth wear. In regression analysis, only energy drink consumption (OR = 3.5, 95% CI: 1.39, 8.9), low secretion of stimulated saliva (OR = 36.3, 95% CI: 4.71, 78.94), and feeling pain/icing (OR = 8.8, 95% CI: 1.92, 40.04) remained significant. CONCLUSIONS The examiners of the study reported that the EWAR tool appeared to be an affordable and easy-to-use instrument. Some challenges occurred during the saliva collection process. Inferential analysis revealed that the risk factors/indicators of low stimulated salivary flow, energy drink consumption, and pain/icing with ETW were considered the most important in ETW occurrence. CLINICAL RELEVANCE EWAR tool combined with the BEWE clinical index can be used for ETW risk assessment for epidemiological studies and chairside use.

Abstract
The use of ultrasound for the diagnosis of natural caries lesions with different depths on flat surfaces of permanent molar teeth was studied. A total of 200 freshly extracted permanent molar teeth with natural caries lesions were included. After evaluation with International Caries and Detection Assessment System II (ICDAS II), mineral loss and lesions in the teeth were detected with a fluorescence device, FluoreCam and lesion depths were measured using ultrasound. The teeth were sectioned and examined histologically using a microscope. The intraclass correlation coefficient was 0.97 for the ultrasound system, 0.65 for the ICDAS II classification and 0.59 for FluoreCam (p < 0.001 for all). With an increase in ICDAS II scores, mean ultrasound values, FluoreCam-Size and microscope measurements increased numerically, while FluoreCam-Intensity and FluoreCam-Impact measurements inversely decreased (p < 0.001). There was a high level of agreement between histologic diagnosis and ultrasound. Ultrasound and FluoreCam can be used to detect enamel caries on flat surfaces.

Abstract
The aim of this study was to determine the correlation between laser fluorescence (LF) values of apparently sound tooth enamel and caries history. LF measurements were recorded from six sound enamel tooth surfaces in each of 346 subjects aged 8-25 years. Caries experience was evaluated using the decayed, missing, and filled tooth (DMFT) index and the International Caries Detection and Assessment System (ICDAS). To measure differences between the unrestored and restored tooth groups, an unpaired two-sample t-test was used. To assess the relationship between LF of sound enamel and caries experience based on the DMFT and ICDAS, Pearson's correlation coefficient and linear regression analyses were used. The LF values of sound dental enamel in subjects with no history of invasive dental treatment were highly correlated with caries experience, as measured by the DMFT index (R = 0.76) and ICDAS (R = 0.7). The LF values of sound enamel in subjects with a history of previous invasive dental treatment were weakly correlated with caries experience, as measured by the DMFT index (R = 0.33), and moderately correlated with the ICDAS values (R = 0.66). The LF value of clinically healthy tooth enamel correlates with caries status based on the DMFT or ICDAS.

Abstract
BACKGROUND Carious lesions are formed by a complex process of chemical interaction between dental enamel and its environment. They can cause cavities and pain, and are expensive to fix. It is hard to characterize in vivo as a result of environment factors and remineralization by ions in the oral cavity. OBJECTIVES The development of a technique that gives early diagnosis which is non-invasive, is of crucial importance for publichealth. Raman spectroscopy is a technique that can fulfil these requirements. The main goal of this work was to use Raman spectroscopy to differentiate between normal and carious human teethinvivo. The samples used in this study were collected by traditional human teeth. MATERIAL AND METHOD An in vivo Raman spectroscopy system andspecialized fiber optic probe has been designed to obtain spectra from tissue. Theseprobes are filtered to reduce the background signal from the fiber optics and the collection fiberutilizes beam steering to optimize the collection effectiv. RESULTS In order to detect any demineralization and carious versus sound pit and fissure enamel, the spectral data sets are analyzed by the proposed scheme to demonstrate the utility of generalized 2D correlation spectra. Potential applications of this 2D correlation approach are then explored. The Raman spectra in the normal tissue showed thepresence of vibrational bands in 437.87 cm-1, 581.89 cm-1, 953.89 cm-1 and 1054.73 cm-1 with smaller intensity than in the carious spectra. Image construction from the peak intensity produced chemical maps of apatite concentration. CONCLUSION Such two-dimensional correlation spectra emphasize spectral features not readily observable in conventional one-dimensional spectra.No correlation is observed in mode-to-mode intensity fluctuations indicating that the changes inmode intensities are completely independent. Theoretical calculations provide convincing evidence that the fluctuationsare not the result of diffusion, orientation or local electromagnetic field gradients but rather are the result of subtle variations ofthe excited-state lifetime, energy and geometry of the molecule and producing a signature response for carious detection.

Abstract
INTRODUCTION The objective of this study was to investigate the association between incisor irregularity and anterior coronal caries by means of an arch-specific analysis among the U.S. population in the National Health and Nutritional Examination Survey (NHANES III) 1988-1994. METHODS This study analyzed data from 9049 participants who were surveyed from 1988 to 1994 as a part of the NHANES III. Participants with a complete set of fully erupted permanent anterior teeth in the maxillary and mandibular segments (ie, canine to canine), who completed an examination of occlusal characteristics and anterior dental caries, and who reported no previous orthodontic treatment were included in the study. Incisor irregularity per arch was determined with the use of the Little irregularity index. Anterior coronal caries per arch was defined as ≥1 surface with decayed or filled surface (CDFS ≥1). Analyses were conducted with the use of chi-square test and logistic regression modeling taking into account the complex sampling design of the survey. RESULTS In the maxillary arch, 25.1% of the study population had maxillary anterior coronal caries experience (CDFS ≥1), whereas only 5.5% of the study population had mandibular anterior coronal caries experience (CDFS ≥1). In both arches, no statistically significant association between incisor irregularity and anterior coronal caries experience was found. CONCLUSIONS Maxillary and mandibular incisor irregularity is not associated with anterior dental caries prevalence in a subset of NHANES III data that included mostly highly educated adult participants who were white, of medium socioeconomic status, and with high oral health compliance and oral self-care. Future well designed prospective cohort studies are needed to confirm these results. Clinicians are still encouraged to continue providing oral health education to their patients about the well established effect of incisor irregularity on plaque retention.

Abstract
The primary aim of the present study was to compare efficiency in detecting suspected caries requiring observation (CO) and decayed teeth (DT) between dental explorers and Community Periodontal Index (CPI)-probes in school dental examinations and evaluate the effect of their respective use on Decayed, Missing, Filled Teeth (DMFT) Index scores. A total of 126 elementary and high school students were examined. All the clinical findings were obtained by a pair of trained dentists examining each student at routine annual school dental examinations. A dental explorer or CPI-probe and dental mirror were used for the examination. One dentist used the dental explorer, while the other used the CPI-probe. The choice of which instrument to use by the first dentist to examine the student was made at random. A comparison of the explorers and CPI-probes revealed that the numbers of patients and permanent teeth classified as CO were greater with the former in 6th-grade elementary and high school students (p<0.05). The Kappa value for CO and DT was 0.560 for 6th-grade elementary school and 0.846 for high school students. All DMFT scores were higher with the explorers than with the CPI-probes in the 6th-grade elementary school students. No significant difference was observed between the explorers and CPI-probes in any of the DMFT scores in any group, however. The present results indicate that as long as the low rate of caries in Japanese school children is maintained, the epidemiological data on this disease should not show any significant change if a CPI-probe is used instead of an explorer in school dental examinations.

J Am Dent Assoc 2018; 149:299-307.e1.

Abstract
BACKGROUND A suspicious occlusal carious lesion (SOCL) can be defined as a lesion with no cavitation and no radiographic radiolucency but for which caries is suspected. The authors evaluated whether using a device changed the percentage of SOCLs that were opened surgically and, among those SOCLs that were opened, the proportion that had penetrated into dentin. METHODS Eighty-two dentists participated. In phase 1 of the study, dentists identified approximately 20 SOCLs, obtained patient consent, and recorded information about the lesion, treatment or treatments, and depth, if opened. Dentists were then randomly assigned into 1 of 3 groups: no device, DIAGNOdent (KaVo), and Spectra (Air Techniques). In phase 2, dentists enrolled approximately 20 additional patients and recorded the same phase 1 information while using the assigned device to help make their treatment decisions. A mixed-model logistic regression was used to determine any differences after randomization in the proportion of lesions opened and, if opened, the proportion of lesions that penetrated into dentin. RESULTS A total of 1,500 SOCLs were enrolled in each phase. No statistically significant difference was found in the change in proportion of lesions receiving invasive treatment from phase 1 to phase 2 across the 3 groups (P = .33) or in the change in proportion of percentage of opened lesions that extended into dentin (P = .31). CONCLUSION Caries-detecting devices in the study did not change substantially dentists' decisions to intervene or the accuracy of the intervention decision in predicting lesion penetration into dentin. PRACTICAL IMPLICATIONS The caries-detecting devices tested may not improve dentists' clinical decision making for SOCLs.

Abstract
Background The objective of this study was to determine the prevalence and severity of general tooth wear (GTW), i.e. tooth wear irrespective of etiology and erosive tooth wear (ETW), i.e. tooth wear predominantly due to erosion; and also to investigate the relationship between ETW and dental caries experience in 16-year-old adolescents in Kuantan, Malaysia. Methods A multi-staged cluster sampling method was employed. A total of 598 16-year-old adolescents participated in this study. Participants’ demographic profile was assessed through a self-administered questionnaire. Clinical examinations were carried out under standardized conditions by a single examiner. The level of GTW was recorded using the modified Smith and Knight’s Tooth Wear Index (TWI) whilst ETW were recorded using the Basic Erosive Wear Examination (BEWE) index. This index was developed to record clinical findings and assist in the decision-making process for the management of erosive tooth wear. Dental caries was recorded using the D3MFT index whereby D3 denotes obvious dental decay into dentine detected visually. Results The prevalence of GTW, ETW and dental caries, i.e. percentage of individuals found to have at least one lesion, was 99.8%, 45.0% and 27.8% respectively. Two thirds of affected teeth with GTW were observed to have a TWI score of 1 whereas almost all of the affected teeth with ETW had a BEWE score of 2. The mean D3MFT was 0.62 (95% CI 0.50, 0.73) with Decayed (D) teeth being the largest component, mean D3T was 0.36 (95% CI 0.30, 0.43). There was no significant association between socio-demographic factors and prevalence of ETW. Logistic regression analysis also showed no significant relationship between the prevalence of ETW and D3MFT (p > 0.05). Conclusions Almost all adolescents examined had GTW but they were mainly early lesions. However, nearly half were found to have ETW of moderate severity (BEWE score 2). No significant relationship between the occurrence of erosive tooth wear and caries was observed in this population.

Abstract
BACKGROUND A lesion on an occlusal tooth surface with no cavitation and no radiographic radiolucency but in which caries is suspected owing to surface roughness, opacities, or staining can be defined as a suspicious occlusal carious lesion (SOCL). The authors' objective was to quantify the characteristics of SOCLs and their relationship to lesion depth and activity after these lesions were opened surgically. METHODS Ninety-three dentists participated in the study. When a consenting patient had an SOCL, information was recorded about the tooth, lesion, treatment provided, and, if the SOCL was opened surgically, its lesion depth. The Rao-Scott cluster-adjusted χ2 test was used to evaluate associations between lesion depth and color, roughness, patient risk, and luster. RESULTS The authors analyzed 1,593 SOCLs. Lesion color varied from yellow/light brown (40%) to dark brown/black (47%), with 13% other colors. Most (69%) of SOCLs had a rough surface when examined with an explorer. Over one-third of the SOCLs (39%) were treated surgically. Of the 585 surgically treated SOCLs, 61% had dentinal caries. There were statistically significant associations between lesion depth and color (P = .03), luster (P = .04), and roughness (P = .01). The authors classified 52% of the patients as being at elevated caries risk. The authors found no significant associations between lesion depth and patient risk (P = .07). CONCLUSIONS Although statistically significant, the clinical characteristics studied do not provide accurate guidance for making definitive treatment decisions and result in high rates of false positives. PRACTICAL IMPLICATIONS Given that 39% of the opened lesions did not have dentinal caries or were inactive, evidence-based preventive management is an appropriate alternative to surgical intervention.

Abstract
Following the consideration of several recent systematic and other reviews, there is a growing professional and scientific consensus that caries measurement methodology in caries clinical trials (CCT) should be updated to reflect progress made elsewhere in cariology. In this paper, therefore, “modern” means accepted in contemporary dental research and dental practice on the basis of sound research evidence—not necessarily new or requiring the use of new technology. Caries measurement should be seen in the context of the objectives of modern clinical caries management and the continuum of disease states, ranging from sub-surface carious changes through to more advanced lesions. Measurement concepts can be applied to at least three levels: the tooth surface, the individual, or the group/population. All are relevant to CCTs. Modern clinical caries management can be seen as comprised of seven discrete but linked steps (Steps 2, 3, and 4 are directly concerned with measurement.): (1) ‘Caries detection’ represents a yes/no decision as to whether caries is present; (2) lesion measurement assesses defined stages of the caries process, taking into account the histopatholgical morphology and appearance of different sizes and types of lesion and the diagnostic threshold(s) being used; (3) lesion monitoring by repeated measures at a series of examinations is used when lesions are less advanced than the stage judged to require operative intervention (A comparison of serial measurements permits the efficacy of preventive care aiming either to arrest or to reverse the lesion to be assessed.); (4) caries activity measures would be very valuable, but are relatively poorly developed and tested at present; (5) diagnosis, prognosis, and clinical decision-making are the important human processes in which all the information obtained from steps 1 to 4 is synthesised; (6) interventions/treatments, both preventive and operative, are now routinely used for caries management; and (7) outcome of caries control/management assesses caries management by examining evidence on the long-term outcomes. A challenge for the future is to define a range of optimal caries measurement methods—in use or in development in recent trials, in clinical practice, and/or in caries epidemiology—that will best contribute to more efficient, modern caries clinical trials.

Abstract
Dental diseases are common in man and range from a toothache to cancers of the head and neck. Dental conditions can affect our capacity to function effectively in areas such as smiling, chewing and speaking. The objective of this study was to describe the main types of dental conditions presenting at the University Hospital between January 2006 and December 2011 and to determine factors associated with the top five diagnosed conditions as well as the acute and chronic conditions. A retrospective review of all 5012 clinical records of dental patients visiting the dental unit within the period stated was carried out. A total of 4196 records which passed the inclusion/exclusion criteria were analysed. Most of the patients who presented were adults. The top 5 dental conditions were apical periodontitis (50.4 %), reversible pulpitis (23.3 %), Gingivitis (11.4 %), Periodontitis (6.2 %) and Halitosis/bad breadth (8.8 %). The top 5 conditions constituted over 75 % of the cases seen. About 84 % of the presentation was acute whilst 16 % was chronic. For the entire dataset and also the top five conditions, approximately 53.0 % were males and 47.0 %. Males outnumbered females on all occasions except for halitosis and most patients presented within 1 month of experiencing symptoms of dental disease. Some significant association was found between the presence of multiple chronic conditions and reversible/irreversible pulpitis. The main dental conditions presenting at the University Hospital during the stated period (i.e. between January 2006 and December 2011) were: apical periodontitis (50.4 %), reversible pulpitis (23.3 %), gingivitis (11.4 %), periodontitis (6.2 %) and halitosis/bad breadth (8.8 %).

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
OBJECTIVE To examine dental caries development and caries risk factors among preschool African American children from low-income families in Detroit, Michigan, over a 4-year window. METHODS Data came from a representative sample of 1021 children (0-5 years) and their caregivers in Detroit. The baseline participants in 2002-2003 (W1) were re-examined in 2004-2005 (W2) and 2007 (W3). Caries was measured using the International Caries Detection and Assessment System. Bivariate and multivariate analyses for repeated data were conducted to explore associations between caries increment outcomes and demographics, access to dental care, oral health-related behaviours, and social and physical environments. RESULTS The mean number of new noncavitated caries lesions (NCCL) was 2.8 between W1 and W2 and 2.6 between W2 and W3, while the mean number of new cavitated caries lesions (CCL) was 2.0 and 2.0, respectively, during the same time periods. In younger children (<3 years old in W1), higher number of new NCCL than new CCL was observed in both W1-W2 and W2-W3. The risk of new NCCL was associated with child's soda intake and caregiver's age. For the risk of new CCL, significant risk factors included baseline NCCL, baseline CCL, as well as child's age. Baseline caries and child's soda intake were also associated with the risk of developing new decayed, missing and filled tooth surfaces. CONCLUSIONS Higher number of new NCCL relative to CCL was developed among low-income African American children during early childhood. New caries development was associated with baseline caries and child's soda intake.

Abstract
OBJECTIVES The aim of this study was to determine the diagnostic accuracy of cone beam computed tomography (CBCT) in the detection of approximal and occlusal noncavitated carious lesions. METHODS A total of 135 extracted human posterior teeth were used. They were radiographed using the following: conventional film (Kodak Insight), a digital system (PSP plates Digora Optime, Soredex), and a CBCT system (NewTom 3G, Quantitative Radiology). All the images were assessed by two independent observers twice. Receiver operating characteristic analysis (Az) was used. RESULTS NewTom 3G 9″ CBCT was statistically inferior to conventional film and a digital system for the detection of approximal caries. NewTom 3G 9″ had significantly higher Az values than PSP plate (p < 0.05), but there were no statistically significant differences between the Az values for CBCT and film (p > 0.33) for occlusal surface caries. CONCLUSION The diagnostic accuracy of all three tested radiographic systems is low, and it is necessary to use other methods to improve early caries detection. CLINICAL RELEVANCE CBCT has found a wide application in different fields of dentistry. The report from a CBCT examination performed for any of these reasons should include all abnormal findings, and the detection of noncavitated caries lesions is especially important because it facilitates the use of noninvasive treatment.

Abstract
OBJECTIVES This study was performed to 1) quantify dentists' treatment thresholds for occlusal primary caries; 2) determine if the patient's age affects dentists' decisions to surgically treat these carious lesions; and 3) test the hypothesis that patients', dentists', and practices' characteristics are significantly associated with surgical enamel intervention. METHODS The study used a cross-sectional design consisting of a questionnaire survey in Japan. This study queried dentists working in outpatient dental practices who were affiliated with the Dental Practice-Based Research Network Japan (JDPBRN), which aims to allow dentists to investigate research questions and share experiences and expertise (n=282). Participants were asked whether they would surgically intervene in a series of cases depicting occlusal caries. Each case included a photograph of an occlusal surface displaying typical characteristics of caries penetration and written descriptions of adult and pediatric patients at high caries risk. RESULTS In a case of a carious lesion within inner enamel, the proportion of dentists who indicated surgical intervention was significantly higher in adult patients (48%) when compared with pediatric patients (34%; p<0.01). Logistic regression analysis showed that using a dental explorer for the diagnosis of primary occlusal caries, type of practice, practice busyness, and percentage of patients who self-pay were significantly associated with dentists' decisions to intervene surgically into the inner enamel carious lesion. CONCLUSIONS These findings demonstrate that more than one-third of participants chose to intervene surgically into inner enamel carious lesions, and patients' age affects dentists' decisions about when to intervene surgically (clinicaltrials.gov registration number NCT01680848).

Abstract
Questionable occlusal carious lesions (QOC) can be defined as an occlusal tooth surface with no cavitation and no radiographic radiolucencies, but caries is suspected due to roughness, surface opacities or staining. An earlier analysis of data from this study indicates 1/3 of patients have a QOC. The objective of this report has been to quantify the characteristics of these common lesions, the diagnostic aids used and the treatment of QOC. A total of 82 dentist and hygienist practitioner-investigators from the USA and Denmark in the National Dental Practice-Based Research Network participated. When consenting patients presented with a QOC, information was recorded about the patient, tooth, lesion and treatments. A total of 2,603 QOC from 1,732 patients were analyzed. The lesions were usually associated with a fissure, on molars, and varied from yellow to black in color. Half presented with a chalky luster and had a rough surface when examined with an explorer. There was an association between color and luster: 10% were chalky-light, 47% were shiny-dark and 42% were mixtures. A higher proportion of chalky than of shiny lesions were light (22 vs. 9%; p < 0.001). Lesions light in color were less common in adults than in pediatric patients (9 vs. 32%; p < 0.001). Lesions that were chalky and light were more common among pediatric than among adult patients (22 vs. 6%; p < 0.001). This is the first study to investigate characteristics of QOC in routine clinical practice. Clinicians commonly face this diagnostic uncertainty. Determining the characteristics of these lesions is relevant when making diagnostic and treatment decisions.

Abstract
BACKGROUND Questionable occlusal caries (QOC) can be defined as clinically suspected caries with no cavitation or radiographic evidence of occlusal caries. To the authors' knowledge, no one has quantified the prevalence of QOC, so this quantification was the authors' objective in conducting this study METHODS A total of 82 dentist and hygienist practitioner-investigators (P-Is) from the United States and Denmark in The Dental Practice-Based Research Network (DPBRN) participated. When patients seeking treatment had at least one unrestored occlusal surface, P-Is quantified their number of unrestored occlusal surfaces and instances of QOC, if applicable. P-Is also recorded information about characteristics of patients who had QOC and had provided informed consent. The authors adjusted for patient clustering within practices. RESULTS Overall, 6,910 patients had at least one unrestored occlusal surface, with a total of 50,445 unrestored surfaces. Thirty-four percent of all patients and 11 percent of unrestored occlusal tooth surfaces among all patients had QOC. Patient- and surface-level QOC prevalences varied significantly according to DPBRN region (P < .001 and P = .03, respectively). The highest percentages for patient- and surface-level prevalence occurred in Florida and Georgia (42 percent and 16 percent, respectively). CONCLUSIONS To the authors' knowledge, this is the first study in which investigators have quantified the prevalence of QOC in routine clinical practice. These results document a high prevalence overall, with wide variation in prevalence among The DPBRN's five main regions. CLINICAL IMPLICATIONS QOC is common in routine practice and warrants further investigation regarding how best to manage it.

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
BACKGROUND A device based on infrared laser fluorescence (IRLF) has become available as an adjunct for the diagnosis of dental caries. AIMS The objective of this study was to clarify the differences of IRLF readings in the mesial, central and distal occlusal pits of first permanent molars. DESIGN Sixty-four children (average age 8.0 years) were examined using IRLF. The mesial, central and distal pits of clinically healthy first permanent molars were measured. The instrument provides measurements in arbitrary units on an open-ended interval scale. RESULTS Mean (± SE) IRLF values in the mesial pits were 4.9 ± 0.4 (upper) and 6.5 ± 0.4 (lower) and were significantly lower than those in the central (8.8 ± 0.6 and 11.5 ± 0.9) and distal (9.6 ± 0.7 and 10.4 ± 0.8) pits in the maxilla and mandible. There was no significant difference between the right (7.3 ± 0.5, 9.4 ± 0.6) and left (8.2 ± 0.5, 9.5 ± 0.6) dental arches. IRLF measurements in the mesial pits of human first permanent sound molars were lower than the central and distal pits in children whose second molars had not erupted. CONCLUSIONS The inherently higher IRLF values of some sites should not be misinterpreted and trigger early invasive treatment.

Abstract
This study assessed the interexaminer and intra-examiner reliability of the Nyvad caries classification system in primary teeth and calculated the mean examination time. The criteria were based on visual and tactile examinations to differentiate active and inactive lesions at cavitated and non-cavitated levels. Eighty children (3-7 yr of age) were examined under standardized conditions by calibrated examiners. At the tooth surface level, reliability was expressed as percentage agreement and kappa coefficient, using four diagnostic thresholds: sound vs. diseased; sound or inactive lesion vs. active lesion; intact surface vs. surface discontinuity; and sound or non-cavitated lesion vs. cavitated lesion. Interexaminer and intra-examiner kappa values were, respectively: 0.82/0.86; 0.80/0.86; 0.90/0.94; and 0.95/0.98. At the individual level, reliability of estimates of the caries prevalence and of the decayed or filled surface (dfs) counts were assessed at three diagnostic thresholds: sound vs. diseased; sound or inactive lesion vs. active lesion; and sound or non-cavitated lesion vs. cavitated lesion. For caries prevalence, interexaminer and intra-examiner kappa values were, respectively: 0.84/0.94; 0.69/0.74; and 0.95/0.97. The mean examination time was 226.5s (SD = 128.5). The use of the Nyvad caries diagnostic criteria in primary teeth showed reliable results. The examination time was acceptable.

Abstract
OBJECTIVE This study aimed to validate the MicroCT for detection of proximal carious lesions in primary molars, using histology as the gold standard. METHODS Forty-eight proximal surfaces of primary molars were examined. Two calibrated examiners conducted the examinations independently. Proximal surfaces were visually scored, using ICDAS. Bitewing radiographs, Micro-CT and histological analyses used caries scores: 0=sound; 1=outer enamel; 2=inner enamel; 3=not spread dentine; 4=outer dentine; 5=inner dentine. Axial and sagital images were used for Micro-CT analysis, whilst for histology, tooth sections (400μm) were analyzed stereomicroscopically (×15). RESULTS Inter-examiner agreement ranged from 0.87 to 0.93 kappa coefficient (k). Histological analysis revealed a frequency of sound tooth surfaces (18.8%) enamel carious lesions (E1) (48%) and dentine carious lesions (D1) (33.3%). MicroCT showed high correlation with histology (r(s)0.88). At both diagnostic thresholds (E1 and D1), sensitivity and accuracy were higher for MicroCT. Inter-device agreement between MicroCT and histology was k=0.81. No difference was found between MicroCT and histology as gold standards for detecting carious lesions using ICDAS. CONCLUSION MicroCT can be used as a gold standard for detecting carious lesions in proximal surfaces in primary molars.

Abstract
UNLABELLED Dental caries is a common disease in children of all ages. It is desirable to know whether children with primary, mixed, and permanent dentitions share risk factors for cavitated and non-cavitated caries. OBJECTIVE To assess the longitudinal associations between caries outcomes and modifiable risk factors. METHODS One hundred and fifty-six children in the Iowa Fluoride Study met inclusion criteria of three dental examinations and caries-related risk factor assessments preceding each examination. Surface-specific counts of new non-cavitated caries and cavitated caries at the primary (Exam 1: age 5), mixed (Exam 2: age 9) and permanent (Exam 3: age 13) dentition examinations were outcome variables. Explanatory variables were caries-related factors, including averaged beverage exposure frequencies, tooth brushing frequencies, and composite water fluoride levels collected from 3-5, 6-8, and 11-13 years, dentition category, socioeconomic status, and gender. Generalized linear mixed models (GLMMs) were used to explore the relationships between new non-cavitated or cavitated caries and caries-related variables. RESULTS Greater frequency of 100 percent juice exposure was significantly associated with fewer non-cavitated and cavitated caries surfaces. Greater tooth brushing frequency and high socioeconomic status (SES) were significantly associated with fewer new non-cavitated caries. Children had significantly more new cavitated caries surfaces at the mixed dentition examination than at the primary and permanent dentition examinations. CONCLUSIONS There were common caries-related factors for more new non-cavitated caries across the three exams, including less frequent 100 percent juice exposure, lower tooth brushing frequency and lower SES. Less frequent 100 percent juice exposures might be associated with higher exposures to several other cariogenic beverages.

Abstract
UNLABELLED OBJECTIVES. The authors report on a study aimed at quantifying the carious lesion depths at which dentists intervene surgically for cases of varying caries penetration and caries risk. They also aimed to identify characteristics that are associated with surgical intervention. METHODS The investigators surveyed dentists enrolled in a dental practice-based research network who reported performing at least some restorative dentistry. In the survey, dentists were asked to indicate whether they would intervene surgically in a series of cases involving occlusal caries. Each case presentation included a photograph of an occlusal surface displaying typical characteristics of caries penetration and a written description of a patient at a specific level of risk of developing caries. Using logistic regression, the authors analyzed associations between surgical treatment with dentists' and practices' characteristics and patients' caries risk levels. RESULTS A total of 517 DPBRN practitioner-investigators responded to the questionnaire. Sixty-three percent of the respondents (326 of 517) indicated that in patients at low risk of developing caries, they would surgically restore teeth with lesions located in inner enamel surfaces and 90 percent would surgically restore teeth with lesions located in outer dentin surfaces. Regarding patients with a high risk of developing caries, 77 percent (398 of 517) of the respondents reported that they would surgically restore inner enamel lesions, and 94 percent (486 of 517) reported that they would restore lesions located on the outer dentin surface. Dentists who did not assess caries risk were more likely than dentists who did assess risk to intervene with dentinal lesions (P = .004). Practitioner-investigators who were in solo practice or a private practice with fewer than four dentists were significantly more likely to intervene surgically with enamel lesions than were dentists in large group practices (those with four or more dentists) (P < .001).

Abstract
OBJETIVO: Avaliar a influência de variáveis socioeconômicas, clínicas e demográfica na experiência de cárie em pré-escolares de 5 anos de idade da cidade de Piracicaba. METODOLOGIA: A amostra consistiu de 728 crianças matriculadas em 22 pré-escolas públicas (n = 428) e 18 pré-escolas privadas (n = 300). A cárie dentária foi avaliada pelos índices ceo-d e ceo-s e pela detecção de lesão inicial (LI). Outras variáveis clínicas como gengivite, apinhamento, espaçamento, fluorose e respiração bucal também foram coletadas. As variáveis socioeconômicas (renda familiar mensal, número de residentes na mesma casa, escolaridade do pai e da mãe, habitação e posse de automóvel) foram obtidas por meio de um questionário semi-estruturado enviado aos pais. RESULTADOS: As médias (desvio-padrão) do ceo-d e ceo-s foram de 1,30 (2,47) e 3,08 (7,55), respectivamente, sendo que 62,2% da amostra estava livre de cárie. As médias (desvio-padrão) do ceo-d+LI e ceo-s+LI foram 1,72 (3,36) e 3,45 (7,94), respectivamente e 59,7% estavam livres de cáries. Por meio da análise de regressão logística múltipla, as crianças com fluorose (Odds Ratio-OR=0,40) ou de famílias com renda superior a 4 salários mínimos (OR = 0,49) apresentaram menor probabilidade de ter experiência de cárie. Aquelas com gengivite (OR = 1,87) tiveram maior chance de ter a doença. Para o critério de diagnóstico de cárie com a inclusão de LI, as crianças com fluorose (OR = 0,39) ou de famílias com renda superior a 4 salários mínimos (OR = 0,52) tiveram menor chance de ter cárie. Aquelas com gengivite (OR=1,80), apinhamento (OR = 2,63 e OR = 1,01) ou respiração bucal (OR = 1,37) apresentaram maior probabilidade de ter a doença. CONCLUSÃO: Os pré-escolares que apresentaram gengivite, apinhamento, respiração bucal ou renda familiar mensal inferior a 4 salários mínimos tiveram maior probabilidade de ter experiência de cárie. Assim, o planejamento de ações de prevenção e intervenção direcionadas a este público seria essencial para o controle da doença.

Abstract
The aim of this study was to assess the frequency of routine use of dental prophylaxis prior to visual inspection, in order to diagnose caries, by dentists with different lapses of time after graduating time. One hundred and fifty one Brazilian dentists were interviewed in 3 Brazilian cities to determine if they usually remove dental plaque prior to visual inspection for caries diagnosis. The dentists were stratified according to year of graduation. The association between the lapse of time after graduating and the practice of routinely removing dental plaque before clinical examination was tested using the chi-square test with a significance level of 5%. Only 28.5% of the dentists reported that they usually remove dental plaque prior to clinical examination. The dentists who graduated in the last 15 years presented the lowest percentages of plaque removal prior to clinical examination (15.1%), whereas the more experienced dentists reported that they perform prophylaxis more frequently. Of the professionals who graduated from 1960-1975, 23.9% reported that they performed dental plaque removal prior to diagnosis, whereas the figure for those graduating from 1976-1990 was 46.2%. Most of the dentists interviewed reported that they did not remove dental plaque prior to performing visual diagnosis of caries.

Abstract
The purpose of this study was to assess the longitudinal relationships between enamel hypoplasia and caries experience of primary second molars. The study sample was 491 subjects who received dental examinations at both age 5 and 9 by the calibrated examiners. Four primary second molars (n = 1,892) were scored for the presence of enamel hypoplasia for each participant. Caries presence and number of decayed and filled surfaces (dfs) were determined at age 5 and 9. The relationships between enamel hypoplasia and caries experience were assessed. Among primary second molars, 3.9% of children and 1.7% of primary second molars had enamel hypoplasia. At age 5, 36.8% of children with hypoplasia had caries, while 16.9% of children without enamel hypoplasia had caries. At age 9, the corresponding numbers were 52.6% for children with hypoplasia and 34.5% for children without hypoplasia, respectively. At the tooth level, for age 5, 28.1% of teeth with hypoplasia had caries (mean dfs = 0.40), and 7.6% of teeth without hypoplasia had caries (mean dfs = 0.11). At age 9, the corresponding numbers were 41.9% (mean dfs = 0.76) for teeth with hypoplasia and 18.3% (mean dfs = 0.34) for teeth without hypoplasia. In multivariable logistic regression analyses, teeth of subjects with enamel hypoplasia had a significantly higher risk for caries at age 5 and 9 after controlling for other risk factors. Enamel hypoplasia appears to be a significant risk factor for caries and should be considered in caries risk assessment.

Abstract
The aim of this study was to assess the reliability of the Nyvad visual-tactile caries-diagnostic criteria when used among children who have been lifelong residents in areas with 'optimal' or low concentrations of fluoride in the drinking water. In each of two areas with drinking water fluoride concentrations of 0.3 and 1.1 ppm (0.3 and 1.1 mg/l) fluoride, respectively, 150 children were clinically examined twice, 2 wk apart, for dental fluorosis, using the Thylstrup-Fejerskov index (TF index), and for dental caries using the Nyvad visual-tactile caries criteria. The prevalence of dental fluorosis was 45% in the 1.1 ppm fluoride area and 21% in the 0.3 ppm fluoride area. When the results of the duplicate caries recordings were compared at the surface level, only minute differences were observed in the percentage agreement (91.7 and 90.7%, respectively) and in the kappa values (0.73 and 0.72, respectively). When individual DFS counts were compared across examinations using Bland-Altman plots and estimation of prediction intervals for the differences, we observed a greater variability of the differences between recordings among children from the low-fluoride area. Contrary to our expectations, a pronounced dental fluorosis background did not reduce the reliability of the caries recordings, which appeared to be slightly less reliable at very low levels of dental fluorosis.

Abstract
OBJECTIVES Bottled water consumption in the United States has greatly increased in the past decade. Because the majority of commercial bottled water is low in fluoride, there is the potential for an increase in dental caries. In these secondary data analyses, associations between bottled water use and dental caries were explored. METHODS Subjects (n = 413) are in the Iowa Fluoride Study, which included dental examinations of the primary (approximately aged 5) and early erupting permanent (approximately aged 9) dentitions by trained dentist examiners. Permanent tooth caries and primary second molar increments were related to bottled water use using logistic and negative binomial regression models. All models were adjusted for age and the frequency of toothbrushing. RESULTS Bottled water use in this cohort was fairly limited (approximately 10 percent). While bottled water users had significantly lower fluoride intakes, especially fluoride from water, there were no significant differences found in either permanent tooth caries (P = 0.20 and 0.91 for prevalence and D(2+)FS, respectively) or primary second molar caries (P = 0.94 and 0.74 for incidence and d(2+)fs increment, respectively). Results for smooth surfaces differed somewhat from those for pit and fissure surfaces, but neither showed significant differences related to bottled water use. CONCLUSION While bottled water users had significantly lower fluoride intakes, this study found no conclusive evidence of an association with increased caries. Further study is warranted, preferably using studies designed specifically to address this research question.

Abstract
OBJECTIVES (a) To analyze the intra- and inter-examiner reproducibility (reliability) of a calibration trial, at different diagnostic thresholds of dental caries; (b) to verify the accuracy (benchmark validity) though sensitivity (S), specificity (SP), positive (PPV) and negative predictive (NPV) values. PARTICIPANTS A group of dental examiners (n=11), who had previous experience in epidemiological surveys and six to seven-year-old children. Children were selected according to the dmft and dental caries activity. METHODS Theoretical and clinical training and calibration exercises were arranged for a total of 28 hours. WHO criteria including the active initial lesions (IL) were used. MAIN OUTCOME MEASURES WHO and WHO+IL diagnostic thresholds according to tooth and dental surface. RESULTS Excellent mean results of intra and inter-examiner Kappa values were found for both diagnostic thresholds, according to tooth and surface, during the calibration phase. The most relevant errors were related to IL diagnosis and to the first permanent molars. When assessed against a benchmark examiner, moderate to high validity values were observed (0.71-1.00), with some loss mainly for sensitivity and positive predictive value, when including IL. CONCLUSION It was possible and feasible to use the proposed methodology of this study in epidemiological surveys, even with the inclusion of IL. However, further examiner calibration studies are still needed in order to improve and establish a methodology of calibration with this new diagnostic threshold.

Abstract
Dental caries, otherwise known as tooth decay, is one of the most prevalent chronic diseases of people worldwide; individuals are susceptible to this disease throughout their lifetime. Dental caries forms through a complex interaction over time between acid-producing bacteria and fermentable carbohydrate, and many host factors including teeth and saliva. The disease develops in both the crowns and roots of teeth, and it can arise in early childhood as an aggressive tooth decay that affects the primary teeth of infants and toddlers. Risk for caries includes physical, biological, environmental, behavioural, and lifestyle-related factors such as high numbers of cariogenic bacteria, inadequate salivary flow, insufficient fluoride exposure, poor oral hygiene, inappropriate methods of feeding infants, and poverty. The approach to primary prevention should be based on common risk factors. Secondary prevention and treatment should focus on management of the caries process over time for individual patients, with a minimally invasive, tissue-preserving approach.

Abstract
OBJECTIVES AND METHODS This study investigated the sealing ability of a current available unfilled fissure sealant applied over sound (n=80), artificially created (n=80) and naturally carious fissures (n=80) under different humidity conditions (90+/-2 and 45+/-2% relative humidity) and etching times (40 and 60s). All samples were submitted to 5000 thermal cycles and examined by light microscopy after sectioning. Microleakage, penetration ability, fissure type, fissure entrance angle, sealant occlusal length, caries location and caries depth were assessed. RESULTS The significantly longer sealant occlusal length and larger entrance angle exhibited by shallow fissures, contributed to their higher microleakage and smaller amounts of unfilled areas compared to deep fissures. Sealant microleakage was significantly influenced by the condition of the enamel (sound, artificial and natural caries) and the caries location in the fissures, but not by enamel caries depth (D1 and D2), etching time, or humidity condition. Natural caries exhibited significantly higher microleakage than sound or artificially created carious fissures. CONCLUSIONS Based on the results of this study, it can be concluded that location of caries in the fissure rather than its depth should be taken into account when applying a fissure sealant. When the borders of the fissure sealant are on carious enamel, a significantly higher microleakage must be expected. The artificial caries model was not a suitable method to assess the behavior of natural fissure caries.

Abstract
Recent years have seen an increase in research activity surrounding diagnostic methods, particularly in the assessment of early caries lesions. The drive for this has come from two disparate directions. The first is from the dentifrice industry who are keen to develop techniques that would permit caries clinical trials (CCTs) to be reduced in duration and subject numbers to permit the investigation of novel new anti-caries actives. The second is from clinicians who, armed with the therapies to remineralise early lesions are now seeking methods to reliably detect such demineralised areas and implement true preventative dentistry. This review examines novel technologies and the research supporting their use. Techniques based on visual, optical, radiographic and some emerging technologies are discussed. Each have their benefits although systems based on the auto-fluorescence (such as QLF) of teeth and electrical resistance (such as ECM) seem to offer the most hope for achieving reliable, accurate detection of the earliest stages of enamel demineralisation.

Abstract
In this article, the fundamentals of caries diagnosis are reviewed from the three component perspectives, namely the strategy, the logics, and the tactics. Strategy concerns the objectives of the diagnostic process (i.e. why we diagnose caries). The logics describe how we assemble and evaluate the information collected and how this leads to an assessment of diagnostic value. Finally, tactics are about how we collect the information necessary to arrive at a correct diagnosis. We argue that the hitherto-dominant essentialistic caries paradigm should be replaced by a nominalistic caries concept. This allows us to circumvent the problem of a lack of a caries gold standard and to proceed in caries-diagnostic research to find the diagnostic methods that result in the best health outcomes for our patients. We also demonstrate the limitations of the medical model when attempting to understand caries diagnosis, and adhere to the Bader & Shugars caries script model. It is concluded that the current caries profile, characterized by lower prevalence and extent, and slower progression, has increased the need for an academic strengthening of the dental curriculum with respect to diagnostic reasoning and clinical decision-making processes.

Abstract
OBJECTIVES This study reports changes in non-cavitated tooth surface diagnoses after a 4-year period. METHODS Dental examinations were conducted for Iowa Fluoride Study cohort children who had non-cavitated lesions in the primary dentition and were also examined an average of 4 years later in the mixed dentition. Comparison of fluoride exposures, socioeconomic factors, and beverage consumption patterns were made between children who had lesions progress and those who did not. RESULTS Of 129 non-cavitated pit and fissure lesions in the first exams, 40 (31%) progressed to either frank decay or filled status, while among 132 noncavitated smooth surface lesions, 7 (5%) were filled and none had frank decay in the second exam. No fluoride, socioeconomic status or beverage variables were significantly associated with lesion progression. CONCLUSIONS Non-cavitated smooth surface lesions rarely progressed in this age group, but nearly one-third of pit and fissure lesions progressed.

Abstract
OBJECTIVE To analyze the reproducibility of a calibration trial, at different diagnostic thresholds of dental caries, in a 12-month evaluation. METHODS A group of dental examiners (n = 11), who had previous experience in epidemiological surveys, participated in the study. An initial training phase (theoretical and clinical) and five calibration exercises (baseline, 3, 6, 9 and 12 months) were arranged. World Health Organization (WHO) criteria, including the active initial lesions (IL) were used. Six- to 7-year-old children took part in the study. They were selected according to past history and dental caries activity. The data were analyzed at WHO and WHO + IL diagnostic thresholds in accordance with tooth and dental surfaces. RESULTS Excellent mean intra- and inter-examiner Kappa values were obtained for both diagnostic thresholds, in accordance with tooth and surface, during the calibration phases. However, the most relevant errors were related to the decayed component and to IL diagnosis. CONCLUSION It was possible to use the methodology proposed in this study in epidemiological surveys when examining the mixed dentition, although new strategies to improve training in IL diagnosis and calibration are necessary.
