Abstract
AIMS Limited data exist on the effectiveness of oral health preventive programs in children with Neurodevelopmental Disorders (NDD). The aim of this study was to evaluate the effectiveness of an individualized preventive oral health program for preschool children with NDD at a rehabilitation center, over a two years period. METHODS AND RESULTS In this study, 102 preschool children with NDD were assessed for caries (dmft), oral hygiene status (Green & Vermillion Index) and presence of developmental dental defects. An individualized preventive program was applied based on caries risk and children were followed for two years. Effectiveness of the program was assessed for caries and dental plaque change and explanatory individual factors were used in multivariate models. After two years prospective, dmft increased significantly from 1.1 (SD = 2.7) to 2.04 (SD = 3.6), while GVPI was reduced significantly from 1.8 (SD = 0.9) to 1.4 (SD = 0.9). Children in the moderate and high-risk groups missed significantly more follow-ups compared to the low caries risk group (p < .001) while older maternal age (OR = 1.38, 95%CI = 1.057-1.808) and consumption of more than three sugary snacks/day (OR = 0.005, 95%CI = 0-0.0794) were significantly correlated with dental caries. CONCLUSION The individualized preventive program for preschool children with NDD was effective in improving oral hygiene but not dental caries status.

Abstract
PURPOSE Genetic variants of AMELX gene can affect the protein content, organization of enamel prisms, microstructure and microhardness of the enamel, thus altering the caries susceptibility. The present study aims to assess the association between polymorphisms rs17878486, rs5934997, and rs5933871 of AMELX gene and Early Childhood Caries (ECC). MATERIALS AND METHODS This case-control study was conducted on 200 participants, aged 3-6 years, with 100 controls and 100 children with ECC. A questionnaire was used to collect demographic data, birth-weight, type of delivery, oral hygiene practices, feeding history and 24-h diet diary. DNA was isolated from blood and subjected to PCR followed by Sanger sequencing. RESULTS The CC genotype of rs17878486 showed an OR of 1.93 (0.34-10.81; P = 0.73). In a recessive model, the CC genotype of rs17878486 reported an OR of 2.04 (0.36-11.40; P = 0.68); rs5593871 reported an OR of 1.00 (0.31-3.21). Statistically significant differences (P ≤ 0.05) between genotype and allele frequencies of rs17878486, rs5934997, and rs5933871 were not observed between children with ECC and the controls. CONCLUSION Polymorphisms of AMELX gene did not show a significant association with ECC in this population. However, documentation of genetic data in a global context of ECC may be essential for the future.

Abstract
PURPOSE Organ transplantation is an effective treatment for children with severe heart, liver, and kidney diseases. These patient groups may have more oral and dental diseases than healthy controls. It is important to eliminate oral infection foci before transplantation and to maintain good oral health to avoid potential post-transplant complications. The aim of this study was to describe and compare oral health in Finnish paediatric heart, liver, and kidney transplant recipients prior to organ transplantation. METHODS Eighty-six children who received a heart (n = 21), liver (n = 19), or kidney (n = 46) transplant in Finland during the years 2014-2018 were included in this study. The inclusion criterion was a pre-transplantation oral examination. Oral hygiene, enamel anomalies, and the number of decayed, missing, and filled teeth (dmft/DMFT) were analyzed retrospectively from medical and dental records and compared between the three patient groups. RESULTS Children with liver (p = 0.043) or heart (p = 0.047) disease had higher combined primary and permanent dentition dmft/DMFT scores compared to children with kidney disease. A higher combined dmft/DMFT score was associated with poor oral hygiene (p = 0.005). No significant differences in oral hygiene between the patient groups were found. Furthermore, all patient groups had a high prevalence of developmental dental defects. CONCLUSION Children with liver or heart disease seem to have a higher combined dmft/DMFT score, indicating a higher prevalence of caries compared to children with kidney disease. Prevention of dental caries, along with promoting a good oral hygiene routine and regular check-ups, is suggested in these patient groups.

Abstract
Histone methylation assumes a crucial role in the intricate process of enamel development. Our study has illuminated the substantial prevalence of H3K4me3 distribution, spanning from the cap stage to the late bell stage of dental germs. In order to delve into the role of H3K4me3 modification in amelogenesis and unravel the underlying mechanisms, we performed a conditional knockout of Ash2l, a core subunit essential for the establishment of H3K4me3 within the dental epithelium of mice. The absence of Ash2l resulted in reduced H3K4me3 modification, subsequently leading to abnormal morphology of dental germ at the late bell stage. Notably, knockout of Ash2l resulted in a loss of polarity in ameloblasts and odontoblasts. The proliferation and apoptosis of the inner enamel epithelium cells underwent dysregulation. Moreover, there was a notable reduction in the expression of matrix-related genes, Amelx and Dspp, accompanied with impaired enamel and dentin formation. Cut&Tag-seq (cleavage under targets and tagmentation sequencing) analysis substantiated a reduction of H3K4me3 modification on Shh, Trp63, Sp6, and others in the dental epithelium of Ash2l knockout mice. Validation through real-time polymerase chain reaction, immunohistochemistry, and immunofluorescence consistently affirmed the observed downregulation of Shh and Sp6 in the dental epithelium following Ash2l knockout. Intriguingly, the expression of Trp63 isomers, DNp63 and TAp63, was perturbed in Ash2l defect dental epithelium. Furthermore, the downstream target of TAp63, P21, exhibited aberrant expression within the cervical loop of mandibular first molars and incisors. Collectively, our findings suggest that ASH2L orchestrates the regulation of crucial amelogenesis-associated genes, such as Shh, Trp63, and others, by modulating H3K4me3 modification. Loss of ASH2L and H3K4me3 can lead to aberrant differentiation, proliferation, and apoptosis of the dental epithelium by affecting the expression of Shh, Trp63, and others genes, thereby contributing to the defects of amelogenesis.

Abstract
Children can often present with discolouration of their teeth, commonly affecting their permanent maxillary central incisors. These opacities can often cause children to suffer with psychosocial and confidence related issues. With long waiting lists in secondary care, many children may face increased waiting times to receive aesthetic dental treatment. It is important that the dental professional is aware of the different causes of discolouration, the possible treatment options and when to consider a referral to secondary care.

Abstract
This study tests the hypothesis that children 12-30 months born small for gestational age (SGA) aged are more susceptible to severe early childhood caries (S-ECC). We used data on 865 children aged 12-30 months from a prospective cohort study conducted in a city in the northeast of Brazil. The study outcome was S-ECC, defined based on the proportion of decayed tooth surfaces (cavitated or not). The main exposure variable was SGA, defined according to the Kramer criterion and the INTERGROWTH-21st standard. Direct (SGA → S-ECC) and indirect effects were estimated using structural equation modeling, calculating standardized factor loadings (SFL) and P-values (alpha = 5%). The final models showed a good fit. SGA influenced S-ECC in the direct and indirect paths. In the group of SGA children with 12 or more erupted teeth defined according to the Kramer criterion, the direct effect was positive (SFL = 0.163; P = 0.019); while among all SGA children defined according to the INTERGROWTH-21st standard, the direct effect was negative (SFL = - 0.711; P < 0.001). Age and number of erupted teeth may influence the occurrence of S-ECC in SGA children, as the number of teeth affects the time of exposure to disease risk factors.

Abstract
OBJECTIVE To estimate the prevalence of developmental defects in dental enamel and its possible association with prenatal, neonatal and postnatal conditions in six-year-old schoolchildren in a southern Brazilian municipality. METHODS A cross-sectional study was conducted involving 655 six-year-old schoolchildren. Sociodemographic and health data were collected through interviews with mothers and children's oral examinations at schools. Multivariate analyses were performed using Poisson regression with robust estimator. RESULTS The prevalence of developmental defects of enamel was 44.0%. Demarcated opacities were the most prevalent, followed by diffuse opacities. Late pregnancy, maternal schooling less than eight years, female gender and child's white skin color were independently associated with the prevalence of demarcated opacities. CONCLUSIONS The prevalence of developmental defects in dental enamel was 44.0%. Late pregnancy, maternal schooling less than eight years, female gender and child's white skin color were associated with the prevalences.

Abstract
Young children need increased access to dental prevention and care. Targeting high caries risk children first helps meet this need. The objective of this study was to develop a parent-completed, easy-to-score, short, accurate caries risk tool for screening in primary health care settings to identify children at increased risk for cavities. A longitudinal, prospective, multisite, cohort study enrolled (primarily through primary health care settings) and followed 985 (out of 1,326) 1-y-old children and their primary caregivers (PCGs) until age 4. The PCG completed a 52-item self-administered questionnaire, and children were examined using the International Caries Detection and Assessment Criteria (ICDAS) at 12 ± 3 mo (baseline), 30 ± 3 mo (80% retention), and 48 ± 3 mo of age (74% retention). Cavitated caries lesion (dmfs = decayed, missing, and filled surfaces; d = ICDAS ≥3) experience at 4 y of age was assessed and tested for associations with questionnaire items using generalized estimating equation models applied to logistic regression. Multivariable analysis used backward model selection, with a limit of 10 items. At age 4, 24% of children had cavitated-level caries experience; 49% were female; 14% were Hispanic, 41% were White, 33% were Black, 2% were other, and 10% were multiracial; 58% enrolled in Medicaid; and 95% lived in urban communities. The age 4 multivariable prediction model, using age 1 responses (area under the receiver operating characteristic curve = 0.73), included the following significant (P < 0.001) variables (odds ratios): child participating in public assistance programs such as Medicaid (1.74), being non-White (1.80-1.96), born premature (1.48), not born by caesarean section (1.28), snacking on sugary snacks (3 or more/d, 2.22; 1-2/d or weekly, 1.55), PCG cleaning the pacifier with juice/soda/honey or sweet drink (2.17), PCG daily sharing/tasting food with child using same spoon/fork/glass (1.32), PCG brushing their teeth less than daily (2.72), PCG's gums bleeding daily when brushing or PCG having no teeth (1.83-2.00), and PCG having cavities/fillings/extractions in past 2 y (1.55). A 10-item caries risk tool at age 1 shows good agreement with cavitated-level caries experience by age 4.

Abstract
Although there are many studies on the health effects of methylmercury (MeHg) toxicity during in utero and early development, little is known about its effects on mineralized tissues present in the oral cavity, such as enamel structure. Therefore, this study evaluated the effects of MeHg exposure on the physico-chemical, ultrastructural and functional properties of mature tooth enamel. Specifically, we studied offspring of mothers exposed to MeHg during the prenatal and postnatal periods which are the developmental stages associated with tooth enamel formation. Female rats were exposed to MeHg at a dose of 40 μg/kg/day for 42 days of pregnancy and lactation. The enamel of offspring was analyzed by (1) Fourier Transform Infrared Spectroscopy and Raman to assess physicochemical composition, (2) Scanning Electron Microscopy for ultrastructural evaluation, (3) Transmitted Polarizing Light Microscopy for analysis of the enamel extracellular matrix, and (4) resistance and hardness were evaluated by microhardness. The results showed that MeHg exposure during this sensitive enamel formation period induced changes in inorganic and organic content and enamel prisms ultrastructure alterations and disturbed the organic extracellular matrix due to a decreased enamel strength. These novel findings establish for the first time that maternal exposure to MeHg pre and postnatal promoted relevant changes in mature enamel of their offspring rats.

Abstract
BACKGROUND Teeth affected with enamel defects (EDs) are at an increased risk of dental caries. In spite of improving oral health status overall in Australia, Indigenous Australians still experience higher rates of dental caries than non-Indigenous Australians. This study reports on the prevalence of EDs and dental caries experience among Indigenous children in the Kimberley region of Western Australia. METHODS Health status of all the primary teeth (ICDAS II criteria) and the presence of EDs on index teeth (modified Dental Defects of Enamel index; DDE) of young Indigenous children who participated in a 2-arm intervention trial was recorded. Generalized estimating equations were used to estimate the association between EDs and dental caries and effect estimates were presented as odds ratios and associated 95% confidence intervals. RESULTS Person-level prevalence, from 237 children (mean age 3.6 years, standard deviation 1.7) assessed for EDs, was 58% and tooth-level prevalence was 24%. Teeth affected with demarcated or diffuse defects were associated with a twofold higher odds of having caries experience, odds ratio (OR) 2.5, 95% confidence interval (CI) 1.7-3.7 and OR 2.7, 95% CI 1.7-4.0 respectively. CONCLUSIONS The presence of EDs among young Indigenous children was associated with a higher odds of caries experience among affected teeth.

Abstract
INTRODUCTION The aim of the study was to compare the effects of a 30 µg/day versus 10 µg/day vitamin D supplementation, given during the two first years of life, on oral health at the age of six to 7 years. METHODS In 2013-2016, we conducted a randomized, double-blinded, clinical trial from age 2 weeks to 2 years of daily vitamin D3 supplementation (10 vs. 30 µg), including 975 healthy infants. For the present follow-up study at age 6-7 years, a sample of 123 children underwent oral examination by investigators blinded to the intervention group. Tooth enamel defect and caries findings, oral rinse active matrix metalloproteinase-8 levels, and tooth eruption were recorded. The intervention groups were compared with χ2 and Mann-Whitney U tests. Associations of the oral health outcomes were evaluated with correlation analysis and logistic regression. RESULTS Of the children (median age 7.4 years, 51% boys), 56% belonged to the 30 µg intervention group. Developmental defect of enamel (DDE) was found in 39% of the children in the 10 µg intervention group and in 53% of the 30 µg group (p = 0.104). In total, 94% of children were vitamin D sufficient (25[OH]D ≥50 nmol/L) and 88% had caries-free teeth. No associations were found between vitamin D intervention group in infancy and oral health or the presence of DDE. CONCLUSION Daily supplementation with 10 µg vitamin D3 in the Northern Hemisphere seems adequate in healthy children younger than 2 years in ensuring good oral health at early school age.

Spanish Paediatricians’ Knowledge, Attitudes and Practices Regarding Oral Health of Children under 6 Years of Age: A Cross-Sectional Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19159550. [PMID: 35954916 PMCID: PMC9367720 DOI: 10.3390/ijerph19159550] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 07/29/2022] [Accepted: 07/31/2022] [Indexed: 12/04/2022]
Abstract
Background: Early Childhood Caries (ECC) is a prevalent chronic pathology, and it has a negative impact on the oral and general health of the child patient. Aim: To evaluate the knowledge, attitudes and practices of Spanish paediatricians regarding early childhood caries according to the professional’s years of experience. Material and Methods: A cross-sectional questionnaire was conducted by Spanish paediatricians via WhatsApp and e-mails from January to April 2021. Data were analysed using Chi-squared test, Fisher’s exact test and Cramer’s V test. Results: There were a total of 359 participants. Most respondents were women (81.3%) with up to 10 years of professional experience (31.2%) in primary health care and public health. In most cases, participants had an excellent knowledge of primary dentition (90.8%), but they ignored (56%) when the first visit to the dentist should occur. Regarding the aetiological factors of caries, oral hygiene and prevention, a lower rate of knowledge was observed. The majority of participants (80.8%) were not able to identify white spot lesions and enamel defects (76%). They considered that their knowledge in oral health was deficient, highlighting the need to increase their training. Less experienced paediatricians were found to have higher success rates. Conclusions: The level of knowledge and attitudes regarding early childhood caries of the evaluated paediatricians should be improved. Paediatricians had difficulties in identifying early caries lesions and enamel defects. Nevertheless, a higher level of knowledge and positive attitudes towards dental caries has been detected among paediatricians with fewer years of professional experience.

Abstract
The erosion of tooth enamel is a common oral disease. The erosion pattern and location and the effects of nanoscale chemical composition on the erosion susceptibility of enamel have been well documented. However, the enamel remineralization accompanied by erosion and its underlying physicochemical mechanisms still remain poorly understood. Here, using rat molars selected for its good relevancy to human teeth, we investigated the remineralization behavior of the outermost enamel surface at the nanoscale level during erosion in diluted hydrochloric acid solutions. While particles on the outermost enamel surface that represent the termination of crystallites protruding to the surface from the near-surface core eroded by acid-attack, the lateral-growth of the particles (i.e., the main remineralization picture of the surface enamel) occurred concurrently. Ionic analyses indicate that the particle growth is driven by the local increase in pH near the eroding enamel surface as a result of the combination of the PO43- and CO32- released from the enamel surface with H+. As the pH increases eventually to the equilibrium pH level (∼5.5), a local supersaturation of solute ions is induced, resulting in particle growth. A simple growth model based on the experimental results together with an assumption that the particle growth is a diffusional process suggests that the particle growth rate is controlled by the degree of supersaturation and accommodation site for solute ions, which are affected by the pH of solution eroding the enamel surface. The remineralization mechanism presented by our study can explain how the enamel on being acid-exposed or tooth decay progress by beverage or food can naturally remineralize in the oral cavity and how remineralization can foster different surface topology at the nanoscale, depending on the pH value of etchant before the dental filling material is applied.

Abstract
All of us who observe the chilling figures of children with dental caries on a daily basis and more recently the more frequent presence of enamel alterations and among them incisor molar hypomineralization, we begin to think what really happens with that tissue considered the strongest. of the human body; however, it bows down to an acid attack resulting from bacterial metabolism. And the question arises: Could it be that the tooth is already born with a predisposition to develop certain microorganisms? This comprehensive review of the literature, summarizing the authors' perspectives; aims to explore the knowledge about the biome and apply it to the dental organ and make available the definition of dentobiome, as an appropriate term for dental flora. Starting from this knowledge, apply it to better understand today the execution of the philosophy of minimal intervention and the development of materials that must be biocompatible with the dental structure but must also prevent dysbiosis and establish homeostasis in the tooth.

Abstract
BACKGROUND Hypomineralised second primary molar (HSPM) is a developmental enamel defect associated with dental caries. AIM To evaluate the impact of HSPM on oral health-related quality of life (OHRQoL) in preschoolers through hierarchical analysis. DESIGN This population-based cross-sectional study assessed 834 5-year-old preschoolers, in Teresina, Piauí, Brazil, using sociodemographic questionnaires and Early Childhood Oral Health Impact Scale (ECOHIS). Dental examination was performed by two calibrated examiners (κ ≥ 0.80) for the diagnosis of HSPM (EAPD), dental caries (dmft and pufa indices), and malocclusion (Foster and Hamilton criteria). Analysis of the determinants of OHRQoL was stratified at three levels (P < .05). RESULTS Severe HSPM was associated with OHRQoL in bivariate analysis (P < .05). In adjusted final multivariate analysis (model 1), the presence of dental caries with or without clinical consequences was associated with worse OHRQoL (P < .05). In model 2, after the removal of dental caries, preschoolers with severe HSPM had greater probability of having a negative impact on OHRQoL in the child impact section (RR = 2.14; 95% CI = 1.26-3.65), family impact section (RR = 1.99; 95% CI = 1.16-3.42), and total score (RR = 2.09; 95% CI = 1.25-3.49) of the ECOHIS. CONCLUSION Severe HSPM had a negative impact on the OHRQoL of preschoolers and their families, but the presence of dental caries neutralised this impact.

Abstract
PURPOSE This study investigates the micro shear bond strength of resin-modified glass ionomer cement (RMGIC) bonded to hypoplastic teeth after the application of chlorhexidine (CHX), sodium hypochlorite (NaOCl), Er;Cr:YSGG and methylene blue mediated antimicrobial photodynamic therapy (APDT). METHODS A total sample of 60 erupted and extracted hypoplastic teeth collected from < 16 years children were subjected to different conditioning protocols including control group that involved bonding of hypoplastic teeth with RMGIC; CHX and NaOCl groups that included hypoplastic enamel being treated with 0.2% CHX and 2% NaOCl solution for 30 s followed by rinsing and drying for 5 s, MB-PDT group involved methylene blue photosensitizer and Er,Cr:YSGG group. All specimens were processed for microshear bond strength in a universal tester. The fractured surface was examined using a stereomicroscope at 40 × magnification and categorized under adhesive, cohesive and mixed. RESULTS The highest microshear bond strength was noted for the control group (∼29 MPa). Whereas the specimens conditioned by NaOCl showed the lowest microshear bond strength (∼17 MPa). Among the treatment groups, APDT showed the highest bond strength values (∼22 MPa) as compared to chemical disinfection protocols. However, Er, Cr:YSGG showed slightly lower microshear bond strength as compared to APDT. No significant difference was noted between CHX and NaOCl groups (p > 0.05). There was a statistically significant difference when all the groups were compared together (p < 0.05). Microscopic analysis revealed that specimens bonded after APDT showed the highest adhesive failures (70%). The highest cohesive failures were seen in NaOCl group (40%). The mixed type of failures was seen in the control groups with none appearing for chemical disinfection protocols. CONCLUSIONS This study concludes that APDT could be a potential therapeutic strategy for increasing the microshear bond strength of RMGIC to hypoplastic enamel.

Abstract
Infant oral mutilation (IOM) is a ritual ceremony practised mostly in African cultures, in which the primary tooth bud of the deciduous canine is extracted. Complications and risks of IOM include pain, heavy bleeding and infection that may deteriorate to life-threating conditions. The main long-term consequence of IOM is future dental abnormalities. The scientific literature lacks in-depth analyses of the dental sequelae of this practice among adults who underwent it, and particularly of the aspect of dental treatment. Eight new cases of IOM are presented in this case series, with emphasis on dental diagnosis and treatment modalities. We describe different outcomes of this practice, such as enamel hypoplasia and crown deformations with later necrosis and infection of the root canal system, severe discolouration, immature root apex, impaction of a canine, failure of development and missing lower permanent incisors and canines, an odontoma-like structure, severe periodontal defect and root dilaceration. Familiarity with the practice of IOM is vital in order to identify its manifestations and arrive at the correct diagnosis and optimal course of treatment.

Abstract
Identifying the risk factors for dental caries is vital in epidemiology and clinical practices for developing effective preventive strategies, both, at the individual and collective levels. Different causality/determination models have been proposed to understand the development process of dental caries. In the present review, we designed a model inspired by the world-known social determinants models proposed in the 90s and more recently in the 10s, wherein the contextual factors are placed more externally and encompass the individual factors. The contextual factors included those related to the cultural and societal values, as well as the social and health government policies. The individual factors were classified into the following categories: socioeconomic (social class, occupation, income, and education level), demographic characteristics (age, sex, and ethnicity), behavioral factors (non-use of fluoride dentifrice, sugar consumption, poor oral hygiene, and lack of preventive dental care), and biological factors (recent caries experience/active caries lesions, biofilm retentive factors, developmental defects of the enamel, disabilities, saliva amount and quality, cariogenic biofilm). Each of these variables was addressed, while focusing on the current evidence from studies conducted in Latin American and Caribbean countries (LACC). Based on the proposed model, educational aspects were addressed, and individual caries risk assessment and management decisions were proposed; further, implications for public health policies and clinical practice were described. The identification of modifiable risk factors for dental caries should be the basis for multi-strategy actions that consider the diversity of Latin American communities.

Twetman S, Boustedt K, Roswall J, Dahlgren J. Systematic review suggests a relationship between moderate to late preterm birth and early childhood caries. Acta Paediatr 2020; 109:2472-2478. [PMID: 32559323 DOI: 10.1111/apa.15424] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/08/2020] [Revised: 06/11/2020] [Accepted: 06/12/2020] [Indexed: 01/28/2023]
Abstract
AIM The aim was to examine the association between moderate to late preterm birth and the prevalence of early childhood caries. METHODS We searched the PubMed, Scopus, Cochrane Trials Register databases up to February 28, 2020. Two independent reviewers screened the papers for relevance, extracted data and assessed the risk of bias. A random-effects meta-analysis was performed to pool the prevalence of early childhood caries by gestational age. RESULTS The authors identified 14 studies covering 210,691 children. They were published from 2007-2020 and included birth cohorts, cross-sectional, register-based and case-control studies. We assessed eight of them as having low or moderate risk of bias. The median caries prevalence was 48.8% among children born moderate to late preterm compared to 20.5% for those born full term. The pooled overall odds ratio was 1.48 (95% confidence interval 1.16-1.89; P < .001). The certainty of this finding was low due to heterogeneity and inconsistencies across the studies. CONCLUSION This systematic review and meta-analysis displayed a significantly higher prevalence of early childhood caries in children born moderate to late preterm compared to full term children. The finding suggests that the gestational age should be collected as a risk factor in the paediatric dental records.

Abstract
Objectives Behavioural and lifestyle factors, as oral hygiene and diet, are well‐established risk factors in the pathogenesis of dental caries, though displaying large differences in susceptibility across individuals. Since enamel formation already starts in utero, pregnancy course and outcome may eventually play a role in enamel strength and caries susceptibility. Therefore, we studied the association between history of pregnancy complications and the caries experience in their six‐year‐old children. The pregnancy complications included small for gestational age (SGA), spontaneous preterm birth (sPTB), gestational hypertension (GH), pre‐eclampsia (PE), individually, and a combination of those, designated as placental syndrome. Methods This study was embedded in Generation R, a prospective longitudinal Dutch multiethnic pregnancy cohort study. Information about pregnancy complications was obtained from questionnaires completed by midwives and obstetricians with cross‐validation in medical records. These included SGA, sPTB, GH and PE. Caries experience was assessed with the decayed, missing and filled teeth (dmft) index at a mean age of six years. The association between dental caries experience and a history of pregnancy complications was studied by using hurdle negative binomial (HNB) models. Results We were able to assess the dmft index in 5323 six‐year‐old children (mean age 6.2 years, SD 0.5). We did not find an association between the different pregnancy complications and dental caries experience in childhood, whether for SGA, sPTB, GH, PE, or for the combined outcome placental syndrome (HNB estimates: OR 1.02, 95%CI 0.87 ‐ 1.19; RR 0.90, 95%CI 0.78 ‐ 1.04). Further adjustment of the models with different confounders did not alter the outcome. Conclusions Although it is expected that prenatal stress can be a risk factor for caries development later in life, our findings do not support this hypothesis. Therefore, we believe disparities in caries experience between children are probably not explained by early life events during a critical intrauterine period of development.

[PMID: 32424746 DOI: 10.1007/s00431-020-03660-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2020] [Revised: 03/24/2020] [Accepted: 04/22/2020] [Indexed: 12/11/2022]
Abstract
Tenofovir disoxoproxil fumarate (TDF) is recommended for antiretroviral treatment for pregnant women living with HIV. As a comparative method to study bone density, we investigated the influence of in utero tenofovir exposure on the prevalence and distribution of developmental defects of enamel (DDE) in the primary dentition, as the mineralization process in teeth is higher and more complex and thus more vulnerable. HIV-exposed children with in utero exposition to tenofovir were included in this prospective observational single-center study. Dental status and enamel defects were assessed by an experienced dentist following a standardized protocol. Further information was collected using a standardized questionnaire, available in German and English. The prevalence of developmental defects in children with intrauterine tenofovir exposure was compared with literature data from a recent study of 377 healthy children in Germany and literature data from a study of 1221 healthy African children. Thirty-one children (mean age 2.1 ± 0.3 years; 41.9% female) were included. Median tenofovir exposure in utero was 28 weeks (mean ± 10.52 SD). Prevalence of developmental defects in the primary dentition in tenofovir-exposed children was similar compared to data of unexposed children (16.1% vs. 5.3%, p = 0.051 (compared to German cohort); 16.1% vs. 33.3%, p = 0.068 (compared to African cohort)).Conclusion: HIV-uninfected infants with in utero exposure to TDF showed no significant differences in the prevalence of DDE in comparison to cross-sectional data of HIV- and TDF-unexposed children; thus, the in utero exposure to TDF did not negatively influence the prevalence or distribution of DDE. What is Known: • There are no data available on the prevalence of developmental defects of enamel (DDE) in the primary dentition in intrauterine HIV- and tenofovir-exposed children. • Conclusions can be drawn from intrauterine milk tooth development to bone development and mineralization. What is New: • Prevalence of developmental defects in the primary dentition in tenofovir-exposed children was similar compared to data of unexposed children. • Preterm birth and hospitalization did not show a significant association on the prevalence of developmental defects in the primary dentition.

Abstract
There has been considerable research focussed on the occurrence and aetiology of developmental defects of enamel, but less is known about the extent to which enamel-defect-affected teeth may be at greater risk for dental caries. The Dunedin Multidisciplinary Health and Development Study is a prospective cohort study of 1,037 children born in Dunedin, New Zealand, between April 1, 1972, and March 31, 1973. Participants were examined for the presence of developmental defects of enamel at the age of 9 years and then repeatedly for the occurrence of dental caries through to the age of 45 years. After controlling for confounding variables, incisor teeth affected by demarcated opacities at the age of 9 were 3.4 times more likely to be restored than teeth unaffected by defects. Incisors with diffuse opacities and hypoplasia or combinations of defects were 2.8 times more likely to be restored. Molars with enamel defects of any type did not have any significantly different risk for being subsequently restored or lost due to caries than unaffected molars, except those affected by diffuse opacities, which were at 0.4 times the risk of being lost due to caries. Dental clinicians should be aware that enamel-defect-affected teeth are not necessarily at greater risk for tooth loss due to caries in the long term, but permanent incisors affected by enamel defects are at higher risk of receiving restorative intervention.

Abstract
Dental erosion has become a prevalence disease and attracted increasing attention worldwide. In this research, we quantitatively evaluate the mechanical and morphological changes in the very early stages of softening and weakening of human enamel surfaces induced by soft drinks using atomic force microscopy (AFM). With an increase of the immersion time in soft drinks, we found a significant increase of surface roughness (Rq) of the enamel surface. The prismatic structure of enamel was clearly observed after a 1-h immersion in Coca-Cola®, which shows its strong erosion effect. According to the elastic modulus mapping images obtained by AFM, a considerable decrease of elastic modulus (E) of enamel surface has been found as the enamel surface structures are etched away by soft drinks. A high surface roughness of enamel will result in a high chance of cavities due to easier bacterial adhesion on rougher surface, while a drastic deterioration of the mechanical properties of the enamel will weaken its protection property. Our findings show the serious influence of acidic drinks on enamel surface at the very beginning stage of etching process, which is quite meaningful for people to prevent dental erosion and keep dental health.

Abstract
Prevention of childhood caries is an ongoing public health challenge, but the possibility of an association with maternal mental disorders has received limited attention. We estimated the extent to which maternal mental disorders are associated with an increased risk of hospitalization due to dental caries. We conducted a longitudinal cohort study of 790,758 infants born in Quebec, Canada between 2006 and 2016, with follow-up extending to 2018. We identified women with mental disorders before or during pregnancy and computed the incidence of dental caries in their children. We estimated HR and 95% CI for the association of maternal mental disorders with the risk of dental caries, adjusted for personal characteristics. Infants of women with mental disorders before or during pregnancy had a higher incidence of dental caries compared to children of women with no mental disorder (56.1 vs. 27.2 per 10,000 person-years). Maternal stress and anxiety disorders (HR = 1.73; 95% CI 1.60-1.86), depression (HR = 1.81; 95% CI 1.60-2.03), schizophrenia and delusional disorders (HR = 1.69; 95% CI 1.29-2.22), and personality disorders (HR = 1.89; 95% CI 1.70-2.11) were associated with the risk of dental caries. The associations were present throughout childhood, including after 7 years (HR = 1.65; 95% CI 1.38-1.96). Maternal mental disorders were associated with caries of the enamel, dentin, and cementum and caries that reached the dental pulp. Maternal mental disorders before or during pregnancy, especially stress and anxiety, depression, schizophrenia, and personality disorders, are associated with the risk of childhood caries. Women with a history of mental disorders may benefit from enhanced strategies for prevention of dental caries in their children.

Abstract
AIM To evaluate the occurrence of developmental defects of enamel (DDE) in children and adolescents with Cerebral Palsy (CP) and to analyze the effect of common factors in the etiology of CP on the occurrence of DDE. METHODS A case-control study was carried out using the modified DDE index to classify enamel defects. The study group (SG) consisted of 45 participants with CP aged between three and 14 years. The control group (CG) consisted of 88 normotypical schoolchildren, paired by gender and age group. Caregivers answered a questionnaire on their socioeconomic status and medical history. The Chi-square tests, bivariate and multivariate analysis were performed (level significance < 0.05). RESULTS The occurrence of DDE in SG and CG was 60% and 64.8%, respectively (p value = 0.726). The most frequent defect observed in SG was diffuse opacity (44.4%), followed by demarcated opacity (26.7%) and enamel hypoplasia (2.2%). No difference was observed in the defect's distribution among both groups (p value = 0.083). For SG, the bivariate analysis revealed a statically significant association between the presence of DDE and age group 7-14 years old and maternal schooling below 11 years. After adjusting for confounding variables, age, family income and maternal schooling were not associated with DDE. CONCLUSION In conclusion, the occurrence of DDE was high and similar in both groups. The pre, peri or post-natal factors associated with CP were not significant for the presence of DDE.

Abstract
OBJECTIVES The purpose of this cross-sectional study was to investigate whether polymorphisms in vitamin D receptor (VDR) genes increase the prevalence of dental caries, molar incisor hypomineralization (MIH), and hypomineralized primary second molars (HPSM). MATERIAL AND METHODS A representative population-based sample of 731 schoolchildren, 8 years of age, was randomly selected in Curitiba, Paraná, Brazil. MIH, HPSM, and dental caries were clinically assessed by four calibrated examiners (kappa > 0.80) using European Academy of Pediatric Dentistry (2003) criteria, the modified Developmental Defects of Enamel (DDE) index, and the Decayed, Missing, or Filled Teeth (DMFT) index by the World Health Organization (2013), respectively. The VDR rs739837 and rs2228570 polymorphisms were genotyped using real-time polymerase chain reaction. Associations were analyzed by Poisson regression with robust variance (α = 0.05). RESULTS Schoolchildren with MIH presented a higher prevalence of dental caries (DMFT > 1, PR = 2.52, confidence interval = 1.60-3.97, p ≤ 0.001). No association was observed between MIH, HPSM, and dental caries, with rs739837 and rs2228570 polymorphisms. Individuals with the GT/GG genotype in rs739837 polymorphism presented a higher prevalence of MIH in molars and incisors than individuals TT (PR = 2.34, confidence interval = 1.08-5.07, p = 0.03). CONCLUSION Children with MIH presented a significant higher prevalence of dental caries than children without MIH. To carry at least one G allele in rs739837 was associated to higher prevalence of MIH in molars and incisors. CLINICAL RELEVANCE Our findings suggested that more severe cases with incisors affected by MIH could be associated with polymorphism in VDR gene.

Abstract
Background Pseudohypoparathyroidism (PHP) is a rare and inherited disease caused by mutations in the GNAS-gene or upstream of the GNAS complex locus. It is characterized by end-organ resistance to PTH, resulting in hypocalcemia and hyperphosphatemia. We aimed to investigate the dental anomalies according to tooth types and the orthodontic characteristics of patients with PHP. Methods Using a cross-sectional design, 29 patients (23 females) with PHP, living in Denmark, were included, and their clinical intraoral photos and radiographs were examined. Results Pulp calcification was found in 76% of the patients. Blunting of root apex was present in 55% and shortening of root in 48% of the examined patients. Blunting and shortening of roots were seen more often in premolars than in other tooth types (pboth < 0.01). Crowding of lower anterior teeth was frequently observed (36%) as well as diastema in the upper arch (25%), midline diastema (18%), and Class III malocclusion (11%). Conclusion In the present study population, the teeth were frequently affected by pulp calcification and/or deviation of the root morphology. Blunting and shortening of root(s) were more often seen in premolars than in other tooth types. Class III malocclusion was relatively prevalent. It is important to pay attention to dental anomalies and occlusion in order to provide adequate care for patients with PHP.

AIM The aim of this study was to assess biomarkers of calcium homeostasis and tooth development, in mothers during pregnancy and their children at birth, for enamel hypoplasia (EH) in the primary maxillary central incisor teeth. METHODS Bayesian methodology was used for secondary data analyses from a randomized, controlled trial of prenatal vitamin D3 supplementation in healthy mothers (N = 350) and a follow-up study of a subset of the children. The biomarkers were serum calcium (Ca), phosphorus (P), intact parathyroid hormone (iPTH), total circulating 25-dihydroxyvitamin D (25(OH)D), and 1,25-dihydroxyvitamin D (1,25(OH)2D). The maternal biomarkers were assayed monthly during pregnancy, and the child's biomarkers were derived from cord blood. Digital images of the child's 2 teeth were scored for EH using Enamel Defects Index criteria for each of the incisal, middle, and cervical regions for an EH extent score. RESULTS The child EH prevalence was 41% (60/145), with most defects present in the incisal and middle tooth regions. Cord blood iPTH and 1,25(OH)2D levels were significantly associated with EH extent after controlling for maternal factors. For every 1 pg/mL increase in cord blood iPTH, the EH extent decreased by approximately 6%. For every 10 pg/mL increase in cord blood 1,25(OH)2D, the EH extent increased by almost 30% (holding all other terms constant and adjusting for subject-level heterogeneity). The relationship between maternal 25(OH)D and maternal mean iPTH varied significantly by EH extent. CONCLUSION The results suggest possible modifiable relationships of maternal and neonatal factors of calcium homeostasis during pregnancy and at birth for EH, contributing to the frontier of knowledge regarding sound tooth development for dental caries prevention.

Abstract
Cystinosis is a rare autosomal recessive lysosomal storage disorder, which leads to abnormal accumulation of cysteine in various organs, including progressive dysfunction of kidneys. The most severe and frequent form, affecting ∼95% of patients, is termed infantile nephropathic cystinosis (NC) (OMIM 219800). We have reported oral findings in two patients with NC and described esthetic and functional rehabilitation in one of them. The first case describes a 16-year-old male patient, who was diagnosed with NC when he was 1-year-old. The patient exhibited generalized enamel hypoplasia, grade 1 drug-induced gingival overgrowth, caries lesion in molar tooth and supernumerary tooth (ie, distomolar). The second case describes a 14-year-old male patient diagnosed with NC at 3 years old. Clinical examination revealed generalized enamel hypoplasia and grade 1 drug-induced gingival overgrowth. Radiographic examination showed supernumerary tooth (mesiodens). The treatment included gingivoplasty and restoration with direct composite resin. The severity of hypoplasia highlights the importance of a dental rehabilitation treatment, as proposed here. Direct restoration with composite resin allowed harmony, function, and esthetics to be restored, in addition to being a rapid and low-cost technique.

Abstract
BACKGROUND Developmental enamel defects (DDE) represent one of the prevalent oral problems in childhood; however, few studies have evaluated its impact on quality of life in the children's own perception. AIM To evaluate the DDE impact on quality of life of 5-year-old children. METHODS This cross-sectional observational study assessed 566 children aged 5 years old, in Teresina, Piauí, Brazil, according to their self-perceptions. Children answered the Pediatric Quality of Life Inventory™ Version 4.0 and Oral Health Scale. The dmft index, modified DDE index and Foster and Hamilton criteria were used to diagnose dental caries, DDE and malocclusion, respectively. A single examiner performed the clinical examination. Descriptive analyses and Poisson regression with robust variance were performed. RESULTS The prevalence of DDE was 33.7%. For children's self-reports, the presence of DDE had a negative association with oral health-related quality of life (OHRQoL; PR 1.09, 95% CI 1.02-1.15). Enamel hypoplasia had a negative impact on the physical function (PR 1.05; 95% CI 1.01-1.10) and oral health (PR 1.06, 95% CI 1.01-1.11) domains. Diffuse opacity had a negative impact on the social aspect (PR 1.09, 95% CI 1.02-1.18). CONCLUSIONS Enamel defects had a negative impact on OHRQoL according to the self-reports of the children.

Abstract
Teeth with developmental defects of enamel (DDE) have porous and/or uneven enamel, making them more susceptible to the build-up of oral biofilm and development of caries and periodontal diseases. The aim of this cross-sectional study was to determine the prevalence of DDE and associated factors among children and adolescents living in a Quilombola community in the Northeast of Brazil. The study population was census-based and comprised individuals aged three to 14 years. The children's parents/guardians answered a questionnaire devised to collect information on socioeconomic and demographic characteristics, health problems during pregnancy and illnesses during early childhood. DDE was diagnosed using the modified DDE index. The data were analyzed using descriptive statistics and Poisson regression with robust standard errors (p<0.05). A total of 406 individuals were examined. DDE prevalence was 80.5%: 42.2% in deciduous teeth and 61.1% in permanent teeth. There was an association between presence of DDE and age (PR=1.09, 95% CI=1.01-1.17), use of antibiotics during pregnancy (PR=1.14, 95% CI=1.07-1.22) and reported malnutrition during early childhood (PR=1.12; 95% CI=1.03-1.22). The findings reveal high prevalence of DDE among children and adolescents living in the Quilombola community. Associated factors were older age, use of antibiotics during pregnancy and malnutrition during early childhood.

Abstract
The risk of dental caries seems to be greater in the presence of developmental defects of enamel (DDE). The aim was to determine whether the presence of DDE in the primary teeth of preschool children increases the risk of dental caries in the primary dentition after a period of approximately 2 years. This study was conducted in two stages: baseline (T0) and follow-up (T1). At T0, examinations were conducted for the diagnosis of enamel defects using the DDE index (FDI, 1992), dental caries, and oral hygiene. The participants were allocated to two groups according to the presence (affected) or absence (unaffected) of DDE. At the second evaluation (T1), examinations were performed for the diagnosis of dental caries. Poisson regression analysis with a multilevel approach was used to determine the association between DDE and dental caries. The two levels of the analysis were tooth and child. Among the 339 children (113 affected and 226 unaffected) examined at baseline (T0), 325 were re-examined at follow-up (T1). According to the multilevel analysis, teeth with enamel hypoplasia had a greater risk of having dental caries (RR: 1.99; 95% CI: 1.19-3.33). The risk of caries was greater on posterior teeth (RR: 2.59; 95% CI: 2.18-3.07) and maxillary teeth (RR: 1.48; 95% CI: 1.26-1.75) that had DDE at T0. On the child level, dental caries at T1 was associated with having dental caries at T0 (RR: 1.38; 95% CI: 1.32-1.46). In conclusion, enamel hypoplasia and previous dental caries are risk factors for carious lesions in the primary dentition.

Abstract
AIM Estimate the prevalence of developmental defects of enamel (DDE) in the primary dentition, describe the distribution among tooth groups and investigate the association with birth weight. METHODS A cross-sectional study was conducted with a sample of 827 children aged 2-5 years representative of the city of Canela in southern Brazil. Demographic characteristics (gender and age) and birth weight were collected from vaccination cards. The diagnosis of DDE was performed by six trained examiners following the criteria of the Federation Dentaire International. DDE were described both jointly and separately as opacity and hypoplasia. Statistical analysis involved the Chi square test, Mann-Whitney test and Poisson regression with robust variance. RESULTS The prevalence of DDE was 55.1% (95% CI 51.6-58.5%), with a mean of 3.0 ± 2.2 teeth affected. Opacity was the more frequent defect (50.4%), followed by hypoplasia (15.5%). Distribution of the defects was uneven, with opacity predominant on second molars and hypoplasia predominant on canines and second molars. Children with a low birth weight did not have a greater probability of opacity (PR: 1.13; 95% CI 0.91-1.41), hypoplasia (PR: 1.33; 95% CI 0.80-2.22) or DDE (PR: 1.11; 95% CI 0.91-1.37). CONCLUSION The prevalence of DDE was high, predominant on second molars and not associated with birth weight. These findings indicate directions for future examination/diagnosis protocols and specific orientations.

Abstract
Dental caries generates significant health, financial and social costs to individuals and communities, but risk factors are not spread randomly and evenly throughout populations. People from lower socio-economic status (SES) and disadvantaged groups suffer a disproportionately greater disease burden. Clinicians and public health experts view this problem through a different lens. Dentists at the clinical coalface consider individual risk factors and behaviours, for example sugar consumption, cariogenic bacteria and poor oral hygiene, as major causes of dental caries. However, considerable evidence suggests that low SES, via traditional individual risk factors as mediators and through additional independent pathways, is another significant cause. Progressive clinical practice uses education, prevention and treatment to reduce the impact of individual risk factors. Policy-makers and health administrators use population-based approaches to improve the health of societies. The authors use literature review to argue for both a greater awareness of the upstream socio-economic causes of dental caries, and action from key community sectors to redress the societal inequalities contributing to dental health inequalities.

Abstract
OBJECTIVE To evaluate studies assessing the prevalence of dental caries and developmental defects of enamel (DDE) in individuals with chronic kidney disease (CKD) in comparison with individuals without CKD. MATERIALS AND METHODS Electronic searches were performed in PubMed, Web of Science, Scopus, Medline via Ovid, and ProQuest databases from their inception date until February 2018. Two review authors independently selected the studies, extracted data, and assessed the methodological quality. Meta-analysis was performed. RESULTS Twenty-seven studies were included in this study. For permanent teeth, 14 studies found that individuals without CKD had higher dental caries scores than those with CKD. However, only five studies presented results with a statistically significant difference between groups. Among the studies evaluating primary teeth, five showed that individuals without CKD had higher dental caries scores than those with CKD. Five studies showed that individuals with CKD had a significantly higher prevalence of DDE than individuals without CKD. The meta-analyses showed that individuals without CKD had significantly higher scores of dental caries teeth and surfaces than individuals with CKD. For DDE, no statistical difference between groups was observed. CONCLUSIONS Individuals with CKD present lower dental caries scores and a higher prevalence of DDE in comparison with individuals without CKD.

Abstract
We used optical coherence tomography to examine the effect of a coating material containing surface reaction-type pre-reacted glass-ionomer (S-PRG) filler on primary enamel demineralization in 18 extracted human primary teeth. The pulp was removed, and each tooth was ultrasonically cleaned with distilled water. Six teeth were treated with 0.1-M lactic acid buffer solution (De group). In the second group (n = 6), a thin film of coating material was applied before demineralization (PRG group). A third group (Control group; n = 6) was maintained in artificial saliva. Using optical coherence tomography, we measured peak signal intensity (dB) and width at 1/e2 (µm) at predetermined locations on the enamel surface and calculated integrated values. All data were analyzed with ANOVA and the Tukey-Kramer test (α = 0.05). Although changes in integrated values differed between groups, there was a small but significant increase in the Control group and a small but significant decrease in the De group. In the PRG group, integrated values were significantly higher at 7 days after the start of the experiment and significantly increased thereafter. Our findings indicate that a coating material containing S-PRG fillers may prevent primary enamel demineralization.

Abstract
Data sourcesPubMed, Web of Knowledge, Scopus and Scielo.Study selectionTwo reviewers identified studies supervised by a third. Observational studies which investigated the association between developmental defects of enamel and dental caries in the primary dentition, which were assessed by clinical examination and published in English, Spanish or Portuguese.Data extraction and synthesisQuality of research was assessed using the critical appraisal checklist from the Joanna Briggs Institute. Meta-analysis was conducted using crude and adjusted association measures (relative risk and odds ratio) with 95% confidence intervals. Combined results were presented as pooled odds ratio, and where necessary were estimated using fixed and random effect models. If heterogeneity was encountered in results, a random effect model was used. Bias was assessed using a funnel plot and the Egger test.ResultsEighteen studies were included in the systematic review and sixteen in meta-analysis; two out of the 16 were cohort studies, the rest being cross-sectional. Twelve of the studies included were conducted in low-income countries. The Egger test showed a degree of bias in some of the studies included. The authors found children with diffuse opacities or hypoplasia had higher odds of having dental caries (OR 1.42, 95% CI; 1.15-1.76; OR 4.29% CI 2.24-8.15), however the presence of demarcated opacities did not show higher odds of caries (OR 2.62, 95% CI 0.85-8.12).ConclusionsThe findings demonstrated an association between developmental defects of enamel and dental caries in the primary dentition. A preventive approach to dental caries and attention to children with enamel defects appears as a useful health promotion and public health strategy. At the individual level, clinicians should be aware that children with enamel defects could require more frequent visits to the dental office in order to reduce the risk of dental caries.
