Molar Incisor Hypomineralization

The aim of this study was to evaluate the risk factors associated with the occurrence of caries in permanent teeth (PT) and in the permanent first molar (PFM) seven years after their eruption. Children born in 2005 who were enrolled in a Community Dental Program were included. A total of 278 children were enrolled. Evaluated risk factors were parental caries experience, educational level of the mother, routine medications, systemic diseases, dietary habits, toothbrushing frequency, existence of molar incisor hypomineralization (MIH) in the PT, and caries in the temporary teeth (TT). Associations between independent variables and the DMF-T (decayed, missing, and filled teeth in PT) and DMF-M (DMF in PFM) indices, only considering cavitated and non-cavitated carious lesions or cavitated carious lesions as outcomes, were evaluated by Poisson regression with robust variance analysis. A cariogenic diet (sweets and soft drinks), toothbrushing frequency of <1 a day, a presence of df-t (decayed and filled temporary teeth) score of >0, low educational level of the mother, and existence of MIH were associated with high DMF-T or DMF-M values (p < 0.05). We can conclude that the intake of sweets and soft drinks, toothbrushing frequency, the presence of caries in TT, and MIH in PT were the best predictors of the occurrence of caries in PT and PFM.

Aim: To evaluate the prevalence and predisposing factors for hypomineralization of second molars in children in primary dentition. Methods: A questionnaire was applied to parents to analyze predisposing factors and to assist in the diagnosis of hypomineralization in children between 2 and 6 years old, followed by an intraoral examination based on indices of non-fluorotic enamel defects in the primary dentition, according to the “Modified Index DDE” to determine demarcated opacity and HSPM presence / severity index to assess hypomineralization. Children from public and private schools were dived into two groups: if they presented HSPM-Group 1 (G1) and if they did not have HSPM-Control group (CG). Results: The most frequent predisposing factors associated with the child were Illness in the first year of life (X2= 6.49; p=0.01) and antibiotic use in the first year of life (X2= 41.82; p= 0.01). The factors associated with the mother were hypertension (X2= 9.36; p=0.01), infections during pregnancy (X2=14.80; p=0.01) and alcohol consumption during pregnancy (X2=97.33; p=0.01). There was a prevalence of 3.9% of HSPM in 14 children, with statistical difference regarding gender (X2 = 4.57; p <0.05), with boys presenting a higher frequency. In G1 hypomineralization was of the type with demarcated opacity, with more prevalent characteristics the yellowish spot, with moderate post-eruptive fracture and acceptable atypical restorations. All lesions were located in the labial region with 1/3 of extension. Conclusion: The prevalence of HSPM in children between 2 and 6 years old was 3.9%, with a predominance in males, with tooth 65 being the most affected. There was an association between HSPM and infection in the first year of life, as well as the use of antibiotics and sensitivity in the teeth affected by the lesion. There was an association between HSPM and hypertension, infection and mothers' alcohol use during pregnancy.

Background. To assess the prevalence and factors associated with malocclusions in children and adolescents with cerebral palsy (CP). Methods. The study included 134 subjects with CP aged 2–18 years enrolled in six rehabilitation institutions and their caregivers, which provided demographic, systemic, and behavioral data. A calibrated researcher held oral examinations with record of the following malocclusion indexes, DAI and DMFT. Poisson regression analysis was used (α < 0.05). Results. About 85.8% (n = 115) of patients had malocclusion. In deciduous and mixed dentition (n = 99), increased overjet (75.8%), open bite (51.5%), posterior cross bite (19.2%), and anterior cross bite (3.0%) were identified. Increased overjet was associated with the age group of 2–5 years and mild communication impairment. Anterior open bite was more common in children who underwent tongue interposition, lip interposition, and pacifier sucking. Communication skills, mouth breathing, and tongue interposition were associated with posterior cross bite. Severe malocclusions (DAI > 30) were observed in 88.6% of patients with permanent dentition (n = 35) and were associated with liquid diet consistency and finger sucking. Conclusion. The prevalence of malocclusion in individuals with CP was high and associated with demographic, behavioral, and systemic factors.

Objective: To determine the prevalence of and factors associated with molar incisor hypomineralization (MIH) in schoolchildren aged 6–12 years. Study design: This study included 1156 schoolchildren aged 6–12 years, living in Mexico City. A previously standardised examiner (k = 0.79) applied the diagnostic criteria for MIH from the European Academy of Paediatric Dentistry. Children's parents completed a questionnaire about medical conditions in the perinatal period and the first 3 years of their children's lives. Descriptive measures were examined, multivariate logistic regression analysis was performed, and odds ratios (ORs) were calculated. Results: The subjects were 582 (50.4%) females and 574 (49.6%) males, with an average age of 8.4 ± 1.6 years. The prevalence of MIH was 15.8%, and this condition was more prevalent in children aged 9–12 years than in those aged 6–8 years (18% vs. 13.7%, p &lt; 0.05). Risk factors for MIH were low birth weight (OR = 1.905, 95% confidence interval [CI] 1.130–3.211, p = 0.014), urinary tract infection (OR = 4.841, 95% CI 2.863–8.186, p = 0.001), chickenpox (OR = 1.826, 95% CI 1.196–2.786, p = 0.005), and history of allergies (OR = 4.370, 95% CI 2.538–7.523, p &lt; 0.001). Conclusions: The prevalence of MIH in a group of Mexican schoolchildren was 15.8%. Medical conditions in the first years of life were more prevalent in children affected by MIH.

<span>This report examines factors associated with integration of online learning in Sydney region high schools. Past studies have shown that schools can be identified as operating at a certain level of use - ranging from non-use, through stages such as entry, and adaptation, arriving at transformation - when a focus on technology shifts to a focus on the learner. This report highlights several factors affecting the use of online learning in Sydney high schools, including systemic factors such as institutional support, as well as micro factors such as teacher capability. After questionnaires and interviews conducted with computer coordinators during 2009, it was found that immediate school factors such as school support and focus on pedagogy were perceived as being more important than broader systemic factors.</span>
