ABSTRACT Aim To evaluate the prevalence of molar incisor hypomineralization (MIH) and its relationship with dental caries in school children of Udupi district. Materials and methods A total of 352 school children were recruited for this study. The European Academy of Pediatric Dentistry (EAPD) 2003, criteria were followed for diagnosis of MIH. Dental caries was recorded using World Health Organization (WHO) guidelines (1997) under natural day light. Results The prevalence of MIH was seen to be 27% (n = 95). A total of 323 teeth had hypomineralization (106 were incisors and 217 were molars). The lower molars (n = 127) were more frequently affected than the upper molars (n = 90). Overall the maxillary incisors (n = 68) were more affected than the mandibular incisors (n = 38). Amongst the children with MIH, the mean number of decayed teeth was significantly lower than mean number of hypomineralized teeth in first permanent molars and first permanent molars and incisors (p < 0.001 and < 0.001) respectively. The mean decayed teeth in first permanent molar and incisors were significantly higher in subjects with MIH than without MIH (p < 0.001). Poisson regression analysis showed a significant positive association between MIH and dental caries (B = 1.43; p < 0.001). Conclusion The prevalence of MIH was relatively high and was associated with dental caries. How to cite this article Tadikonda AN, Acharya S, Pentapati KC.

Background From 2005 to 2015, the prevalence of dental caries in both primary and permanent dentitions was significantly increased in China. Previous studies have shown that the prevalence of permanent dental caries in school-aged children had already reached 19.7%–54.0%, 97.5% affecting first permanent molars. This study aimed to investigate the prevalence and contributing factors of dental caries in 6-year-old children in four regions of China to provide information for oral health promotion programs. Methods A randomized cluster sampling method was employed in the study. All 6-year-old first grade children from the selected schools were invited to receive a clinical oral examination. Dental caries were diagnosed according to the World Health Organization criteria. The erupting first permanent molars were recorded using the modified International Caries Detection Assessment System. Questionnaires assessing children’s oral health-related behaviors and their caretakers’ oral health awareness and attitudes were completed by the children’s parents or guardians. Results Overall, 4,936 6-year-old school children participated in the survey. The prevalence of caries among these children was 87.7%, with a mean number of decayed, missing and filled teeth of 6.04 (SD, 4.24). In primary dentition, the caries prevalence was 87.7%, and the mean dmft score was 6.01 (SD, 4.22). In permanent dentition, the caries prevalence was 2.0%, the mean DFS score was 0.04 (SD, 0.31). All permanent dental caries occurred on the first permanent molars. Carious tooth surfaces were identified as modified ICDAS code “A” to indicate initial caries and distinct visual change in enamel. The mean DAS score of non-cavitated caries in the first permanent molars was 0.18 (SD, 0.67). Logistic regression analysis showed that regional and gender factors were significantly related to the caries experience of these children. Conclusions The 6-year-old children from four regions of China had sever primary dental caries and the first permanent molars were at high risk for dental caries. It is critical to protect permanent teeth from caries as early as the eruption of the first permanent molars.

Background/Aim. Developmental disorders of teeth are the problems that are becoming more present in pediatric dentistry, especially on first permanent molars and incisors. Molar Incisor Hypomineralization (MIH) is proposed term for this phenomenon. The aim of this study was to establish the MIH prevalence in children living in the Foca municipality (Bosnia and Herzegovina) as well as to assess characteristics and expression of hypomineralization within the tested population. Methods. A total of 141 children from the Foca municipality, 8 years of age, were included in this study. Criteria according to Weerhejm have been used for diagnosis of hypomineralization: demarcated opacity (DO), post-eruptive breakdown (PEB), atypical restoration (AR), extracted molars due to MIH (E-MIH) and unerupted tooth (UT). Level and the prominence of color changes have been determined for patients with DO, PEB and AR. Results. MIH in this area was present in 12.8% of children. The prevalence of MIH changes expressed in percentages was as follows: DO was at 9.2%, PEB in 3.5%, AR in 5.6%, while E-MIH was 5.6%. A total of 9.9% of the examinees had mild, 5.6% moderate, and 7.8% severe form of MIH. White form of MIH defects was found in 9.9% of the examinees, white-yellow one in 5.6% and yellow-brown color in 3.5% of the examined children. These changes were more often present in the lower jaw (60.3%). In total, 6.4% of children had these changes present only on molars, while 6.4% of them both on molars and incisors simultaneously. Conclusion. A total of 12.8% of the examinees with MIH is not to be disregarded. With timely diagnosis, prevention and therapy complications could be avoided or mitigated.

Objective. The present study aimed to assess dental status in 7–12-year-old Lithuanian children and to evaluate the extent and the efficiency of the Pit and Fissure Sealing in Permanent Molars program. Material and methods. This cross-sectional study was performed between September 2007 and May 2008. Children, aged 7–12 years, from secondary schools in five biggest cities of Lithuania were invited for the examination using a cluster random sampling method. The data for the present study were collected following the general principles for basic oral health surveys of the World Health Organization. Results. The prevalence of dental caries was 85.5%, 88.9%, and 70.6% in 7–8-, 9–10-, and 12-year olds, respectively. The prevalence of dental caries in permanent molars increased with age and became as high as 57.7% in 12-year-old children. The data showed that the mean number of sealed teeth depends on the county and ranged from 0.83 (1.31) to 1.45 (1.85) in 7–8-year olds, from 0.95 (1.29) to 2.54 (1.15) in 9–10-year olds, and from 0.26 to 2.13 (1.15) in 12-year olds. Conclusions. The prevalence and incidence of dental caries in 7–12-year-old Lithuanian children are high. Only half of all examined children have at least one sealed molar. The financial resources allocated for the Pit and Fissure Sealing in Permanent Molars program were used insufficiently; therefore, there is a need for systematic measures in order to improve the efficacy of the aforementioned program.

Objective: The objective of this study was to investigate the effect of fluoride varnish on remineralization of anterior teeth affected by Molar-Incisor Hypomineralization (MIH) by means of Quantitative Light-Induced Fluorescence- QLF. Study design: Fifty-one healthy 9 – 12- year-old children were selected according to different clinically diagnosed levels of MIH, proposed by the European Academy of Pediatric Dentistry (2003) (considering the most severe lesion per patient, n= 51 lesions), and randomly divided into two groups: (1) four applications of 5% NaF varnish, with one-week interval, and (2) usual home care- control. At each visit, the mean change in fluorescence and area of lesion were measured by QLF. The data were analyzed by repeated measures ANOVA and Tukey's test. Results: All patients showed enamel alterations in first permanent molars and incisors, frequently with two molars affected by MIH (41.1%). There was no statically significant difference in the mean of fluorescence and area of lesion between groups over the studied time. Conclusion: We observed no favorable effect on the remineralization of MIH lesions in anterior teeth after four applications of fluoride varnish.

Background: The aim of this school-based, cross-sectional survey was to investigate the prevalence and risk factors of permanent Molar Incisor Hypomineralization among 7-9 years old school children in Muradnagar. Methods: This cross-sectional study was performed among 7-9 years old school children in Muradnagar. Estimated sample size was 992 in this study. Multistage cluster sampling technique was used in this study in which schools were the clusters which were selected randomly. The study proforma was divided into 2 parts, first part comprised of demographic status, socio-economic status, questionnaires on risk factors of Molar Incisor Hypomineralisation such as prenatal, perinatal and postnal history upto 3 years, feeding pattern, fluoride and other pollutants exposure history, dental history, history of trauma to teeth/face, family history of enamel defects which was asked to the mothers and filled by one examiner in a face to face interview. The second part comprised of recording format of clinical variables assessed by investigator to be recorded by the recording clerk. Molar incisor hypomineralisation were recorded using Modified Developmental Defect of Enamel index developed by Clarkson J.J. and O’ Mullane D.M. in 1989 and dental caries by using Decayed Missing Filled Tooth index (World Health Organization Modification 1997) in which WHO probe was used for examination of dental caries as recommended by WHO in the Oral Health Surveys, Fourth edition; 1997 (Spanish version). Before 1997 modification dental explorer was used for the examination of dental caries. Chi square test, Pearson’s Correlation test, Logistic Regression Analysis and Unpaired t-test were used for analysing the data. Results: The overall prevalence rate of Molar incisor hypomineralisation was 21.4% in this study. Age, problems during pregnancy, normal delivery and childhood illness/ infections are the risk factors which have highest strength of association. Conclusion: In the present study Molar incisor hypomineralisation was found to affect 2 out of every 10 children examined which was higher than that observed in other studies on Indian children.

Introduction: Common oral diseases affecting school children are dental caries, gingivitis and malocclusion. Teeth mostly affected by dental caries in permanent dentition of children are the permanent first molars. Permanent first molars are key factors in occlusion and are most susceptible to dental caries. They maintain arch perimeter and provide best anchorage. Loss of these teeth leads to various problems like space management, tooth migration, problem in mastication and malocclusion. Objective: To assess the clinical status of first permanent molars among 8-12 year school children of Kathmandu. Methods: A cross-sectional study was done among 220 schoolchildren of age 8-12 years randomly selected from 2 private and 2 public schools of Kathmandu. Dental caries, gingival and oral hygiene status were measured by Decayed Missing Filled teeth (DMFT) index, Gingival index and Oral hygiene index-Simplified (OHI-S) respectively. Data was entered in Epidata 3.1 and analyzed in SPSS version 20. Results: The prevalence of dental caries in first permanent molars for study population was 54.5%. Mean DMFT score of first permanent molars was 0.96+1.2. Out of 867 molars examined, 197 (22.7%) were decayed. 98.5% of molars were erupted. Among the total study population, 184 (83.6%) had fair oral hygiene and 203 (83%) had gingivitis. Conclusions: This study shows the need to improve oral health status of first permanent molars of school children through promotion of dental health awareness and curative public health measures at school level.

 Background & Objectives: Worldwide, 60 to 90% of school children have experienced dental caries with higher prevalence in Asian and Latin American countries and poor dental and oral health and untreated oral disease can have a significant impact on quality of life according to WHO report. The objectives of the study were to assess the prevalence of dental caries both in deciduous and permanent teeth and to compare total decayed, filled teeth surfaces among primary school children of Kathmandu from both government and private schools and to find the percentage of first permanent molars affected with dental caries.Materials & Methods: A cross sectional study was conducted among two Government and two Private Primary School Children in Kathmandu district. Total sample were 468 children. Required permission were obtained from concerned authorities. WHO accepted indices for assessing caries designed by Henry T Klein, Carrole E Palmer and Knutson J.W was used. SPSS 20 version software was used for data analysis. Results: Among 468 primary school children examined, 224 were from Government and 244 were from Private school. The prevalence of dental caries was 62 % and more deciduous teeth were decayed. The decayed, filled teeth surfaces in Private and Government school was statistically significant (p=0.000) but gender wise prevalence was statistically insignificant (p=0.303). Among 1st Permanent Molars teeth examined 85% were decayed.Conclusion: This pilot study shows prevalence of dental caries more in deciduous teeth. Among the permanent teeth affected, first permanent molars are in high number.

Purpose: This study aimed to assess the utilization of fissure sealants and their influence on caries reduction in first permanent molars (FPMs) among 6-9 years old female schoolchildren in Dammam, Eastern Province of Saudi Arabia. Materials and Methods: First to fourth grade female children from public schools in Dammam participated in this cross-sectional study. Dental caries and fissure sealants in FPMs were examined clinically using the World Health Organization guidelines. In addition, the parents of the participants responded to a self-reported questionnaire. Results: The study analyzed the data of 449 children. Almost 44.3% of the participants had at least one FPM affected with caries. There were 8.7% of the participants who had fissure sealants in at least one FPM, and out of these, only 2.2% had four FPMs filled with sealants. A significantly greater proportion of participants with sealed FPMs had no caries than the lower proportion of participants without sealants who had caries (P=<0.05). The use of sealants increased significantly from first grade (10.3%) to second grade (30.8%), third grade (38.5%), and fourth grade (20.5%) (P=0.006). High monthly family income (P= 0.047) and having insurance (P=0.017) were significantly associated with increased sealant application. Nearly 21.9% of participants’ parents were aware of caries protective effects of dental sealants. Conclusion: The application of sealants was significantly associated with reduced caries in FPMs. Class year, monthly family income, and insurance were significantly associated with having sealants. Caries prevention programs for children should incorporate sealant application.
