The diagnosis of enamel defects was performed using the Developmental Defects of Enamel (DDE) Index. Through interviews, information was collected on socio-demographic aspects, pregnancy, birthweight, prematurity, and breastfeeding. Statistical analysis was performed using the SPSS program for Windows and involved descriptive analysis, Fisher’s exact test, the chi-square test, and Poisson regression. Results:  The prevalence of developmental defects of enamel was 29.9%. learn more Demarcated opacity was the most frequent type of defect. Children with a history

of very low birthweight had a greater prevalence of enamels defects (PR, 2.7; 95% CI, 1.66–4.61). Prematurity and socio-demographic variables Ponatinib were not associated with enamel defects. Conclusion:  Children with a history of very low birthweight had a greater frequency of enamel defects in primary teeth. “
“Objective.  The aim of this study was to assess the influence of sucking habits and facial pattern measurements on the development of anterior open bite (AOB). Methods. 

A case–control study was carried out on 60 children aged 7 and 8 years attending municipal public schools in the city of Recife, Brazil. Data collection included interviews with guardians, oral examinations, and facial growth pattern analysis using cephalometric radiographs. The following cephalometric measurements were assessed: SN.Gn, SN.GoGn, FMA, and Facial Axis. Statistical analyses were performed using the Student’s t-test and Pearson’s chi-square test at a 5% level of significance. Results.  The percentage of children with sucking habits in the case group was much higher than in the control group (53.3%vs 16.7%) (P = 0.003). Children with sucking habits were six times more likely to develop AOB. Regarding the measurements assessed, no statistically significant differences

were observed between groups. Conclusion.  This study found no evidence that variations L-NAME HCl in cephalometric angles (SN.Gn, FMA, SN.GoGn, and facial axis) are risk factors for AOB. Only sucking habits demonstrated a positive correlation with an increased AOB. “
“Introduction.  It is well established that severe periodontitis clusters in families, but there are no data about the relationship between mothers with chronic periodontitis and their children’s periodontal status. Objective.  To evaluate a risk for periodontal diseases in children of periodontally diseased and healthy mothers. Methods.  Four study groups were included: (I) 20 female patients with untreated generalized severe chronic periodontitis, (II) their children (34), (III) 13 periodontally healthy mothers and (IV) their children (13). Material was collected from years 2004–2006. The clinical examination included registration of visible plaque index, modified gingival index and, bleeding sites on probing.
