“…Diffuse opacity alone and in association with demarcated opacity were the most prevalent defects and accounted for 35% of the observations as previously observed [Ekanayake and van der Hoek, 2003;Kanagaratnam et al, 2009]. This finding was corroborated by a cross-sectional study carried out in 3-to 5-year-olds which examined tooth buccal, lingual and occlusal surfaces for DDE [Lunardelelli and Peres, 2006] and by a longitudinal study in 1-to 3-year-olds in which the defects were more frequently observed on buccal surface (18.4%), than on the lingual (0.8%) and occlusal surfaces (5.9%) [Chaves et al, 2007].…”

“…The examination of plaque-free and dried tooth surfaces under good illumination in our study revealed a higher prevalence of children with DDE (48%) than those reported in other fluoridated areas under various condi-tions, such as clinical examinations carried out under natural light and without plaque removal [Weeks et al, 1993;Li et al, 1996;Lunardelli and Peres, 2006] and teeth examined in wet conditions [Hoffman et al, 2007;Kanagaratnam et al, 2009]. The DDE recording on buccal surfaces was used in our study since these surfaces represent the different periods of tooth formation reasonably [Milsom et al, 1996], have good accessibility and aesthetic importance [Fédération Dentaire Internationale, 1992], show the highest prevalence of developmental defects [Chaves et al, 2007] and are frequently combined with defects on occlusal surfaces.…”

Quantitative defects of the enamel are considered risk factors for caries development at the cavitated level. Since caries risk assessment and control should be implemented as early as possible in order to prevent operative treatment, it seemed interesting to investigate the relationship between enamel defects and caries development in the stages of progression that precede cavitation. The impact of enamel defects and selected child-mother indicators on early caries development was investigated in a cohort of Brazilian preschool children. The null hypothesis that developmental defects of the enamel and dental caries are independent and that an association between them occurs by chance was tested. The sample (n = 1,718) was made up of 2- to 5-year-olds. Developmental defects of enamel and caries on buccal surfaces were identified in 48 and 26% of the children, respectively. Bivariate analyses at the surface level showed neither an association between demarcated/diffuse opacity and caries experience (p ≧ 0.64, GLM), nor between the presence of hypoplastic surfaces and non-cavitated lesions (p = 0.29, GLM). The multivariate analyses indicated that in the mouths of individual children, hypoplastic surfaces were more likely to present filled surfaces and non-cavitated/cavitated lesions than non-hypoplastic surfaces (within-child p = 0.03, GEE). However, children having teeth with hypoplastic surfaces were not at higher caries risk than those children who did not present hypoplastic surfaces (between-child p = 0.23, GEE). The null hypothesis could not be accepted for quantitative defects such as hypoplasia, since they had a significant impact on the within-child prevalence of filled surfaces and non-cavitated/cavitated lesions.

Background: Developmental defects of enamel (DDEs) and dental caries are two prevalent dental conditions that may have major negative impacts on children's quality of life. Fluoride, especially the level of fluoride in water, can influence the occurrence of both dental caries and DDEs. However, data on the extent of this influence on Iranian children has not been explored. Objectives: The aim of this study was to compare DDEs and dental caries in three areas with different levels of fluoride in water among 9-year-old children of the Fars Province, Iran, in order to provide data for oral health preventive programs. Methods: A cross-sectional study was conducted on 400 9-year-old children residing in areas with high, optimal and low levels of fluoride in water of the Fars Province, Iran. Cases with DDE were diagnosed on the standardized one view photographs of the anterior teeth using the modified DDE index. DMFT index was used to evaluate dental caries. The prevalence of children with DDE and dental caries, the mean number of teeth with DDE, and mean DMFT were compared among the three areas by binary logistic and Poisson regressions after adjustment for sex. SPSS software version 22 was used to analyze the data. The significance level was

“…The occurrence of DEO associated with EH —a condition commonly called Molar Incisor Hypomineralization, on the increase as well (4,10). Studies report DDE prevalence in developed countries and healthy children to be in the range of 24% to 49% in primary dentition, and 9% to 63% in permanent teeth (2,8,9,11-21). In Spain, the only studies of DDE prevalence in permanent teeth are limited to recording lesions in incisors and/or first molars (4,22).…”

Objective: The purpose of this study was to determine and compare the prevalence and presentations of developmental defects of the enamel (DDE) in the primary and permanent dentitions of a group of healthy schoolchildren residing in Granada (Spain). Study Design: A total of 1,414 healthy schoolchildren were examined using modified DDE criteria for recording enamel defects. Results: The prevalence of DDE of any type was 40.2% in primary dentition and 52% in permanent dentition (p<0.033). Of the 31,820 primary and permanent teeth examined in the study, 699 (4.1%) primary and 1,232 (8.3%) permanent teeth had some form of DDE. Diffuse opacity was the most common type of DDE observed in primary teeth, and demarcated opacity in the permanent teeth. Enamel hypoplasia was the least prevalent defect in both dentition types. Conclusions: The study population showed a high prevalence of DDE in primary as well as in permanent dentition, reflecting the current increasing trend of this condition, which should be considered as a significant public health problem. Key words:Developmental enamel defects, enamel hypoplasia, demarcated opacity, diffuse opacity.
