Developmental Defects Of Enamel

Introduction. There has been a lack of current epidemiological data regarding the prevalence of developmental defects of enamel in Polish adolescents. Aim. To evaluate the prevalence of developmental defect of enamel in the permanent dentition in the population of adolescents aged 18 years old, including the impact of selected sociodemographic factors. Material and methods. A cross-sectional study conducted in 2017 covered adolescents aged 18 years old attending schools in 16 Polish voivodeships, selected by stratified sampling. Sociodemographic factors such as sex, place of residence, parents’ education level and subjective economic status were collected with a survey. The condition of enamel was assessed with the use of DDE Index modified by Clarkson and Dean’s Indicator by dentists specially trained and calibrated for this study. Prior to its initiation, the study was approved by the Bioethics Committee of the Medical University in Warsaw (Ref. No.: KB/134/217 of 6.06.217). Results. A total of 1611 adolescents were examined (with 52.6% female and 50.5% were residents of rural areas). Developmental defects of enamel were identified in 16.3% of the participants of the study, most frequently in the form of demarcated opacities (10.4%). In 2.7%, they were classified as fluorosis, most frequently questionable. Maxillary central incisors and first premolars were most frequently affected. In 2.5% of the examined adolescents, the defects involved single teeth, whereas in 0.6% the defects were generalised. Defects not classified as fluorosis were more commonly identified in males. There were statistically significant differences in the prevalence between voivodeships, with defects most commonly observed in participants from southern voivodeships. No other sociodemographic factors, however, were identified as significant. Conclusions. The highest prevalence of demarcated opacities suggests the significance of local factors in the aetiology of developmental enamel defects of permanent dentition in Poland. Fluorosis is a rarely encountered entity. The lack of the significance of sociodemographic factors and the regional differences in the prevalence of developmental defects of enamel suggest the need for further research, aimed at identifying geographical risk factors.

Ramus Height

This cross-sectional study investigated mandibular developmental changes in untreated normal Taiwanese from the deciduous to permanent dentition. Differences in the mean values for ramus height and body length between males and females were statistically significant after eruption of the permanent second molars. SNB angles significantly increased and gonial and L1-MP angles significantly decreased from deciduous to permanent dentition in both sexes. The SN-MP angle in females significantly decreased and ramus inclination in males significantly increased from the early mixed to permanent dentition.

Permanent Occlusion

Background: Understanding the association between morphological aspects in the primary dentition and its transition to the permanent dentition provides the possibility of predicting the final permanent occlusion. Study on the occlusal characteristics in deciduous dentition in Nepalese population is limited. This study was aimed to assess the occlusal characteristics and spacing in primary dentition in preschool children. Methods: The cross-sectional study was conducted among 432 preschool children around Kathmandu valley after getting permission from Institutional Review Committee of Kath­mandu Medical College and Teaching Hospital. Each child fulfilling the inclusion criteria was enrolled on the study only after their assent and their parent’s consent. The primary molar relation, canine relation, overjet, overbite was assessed using Foster and Hamilton criteria with the teeth in centric occlusion. Primate and physiological spaces were assessed. Data was collected and analysis was done in SPSS version 16. Results: Among the participants, (51.9%) were male and (48.1%) female. Primate spaces was seen to be absent on157 (36.3%) children. Physiological space was seen among 190 (44%) children. Flush terminal plane molar relationship was more prevalent among 294 (68%) chil­dren. Class I canine relationship was found in 257(59.5%) children. Ideal overjet was seen in 333 (77.1%) children and ideal overbite was seen among 337(78%) children. Conclusions: Favorable characteristics traits were seen in the studied population yet longi­tudinal studies are recommended to predict the possible outcome in permanent dentition.

Background - Little information is available regarding the eruption chronology of Spanish children. Therefore, it is important to acquire accurate eruption parameters for the Spanish population. Aim - To establish the chronology of the permanent dentition. Design - A cross-sectional study based on a sample of 1123 Spanish Caucasian children ranging from 5 to 15 years of age, from three different schools in Barcelona, Spain. Results - The sample is representative of the Spanish population with regards to age, height and weight; and large enough to achieve the desired 95% confidence level. The results appear in the eruption tables included in the body of this paper. Conclusions - In both boys and girls, the lower left central incisor is the first, and the upper right second molar is the last tooth to erupt. Mandibular teeth tend to erupt before the corresponding maxillary teeth; however, there is no difference between the left and right sides of each arch. The results obtained are in agreement with similar studies performed in other groups of Caucasian children.
