The Dental Aesthetic Index and Its Association with Dental Caries, Dental Plaque and Socio-Demographic Variables in Schoolchildren Aged 12 and 15 Years.

The Dental Aesthetic Index (DAI) was determined in 12- and 15-year-old schoolchildren to ascertain the prevalence of malocclusion and to assess its association with dental caries experience, dental plaque accumulation, and socio-demographic variables. We performed a cross-sectional study with a stratified two-stage sampling design. An oral health survey and oral examination were conducted, and socio-demographic data were recorded.

Prevalence and caries-related risk factors in schoolchildren of 12- and 15-year-old: a cross-sectional study.

Background: To assess the prevalence and severity of caries in 12- and 15-year-old schoolchildren, and to analyse the related risk factors.

Methods: We conducted a cross-sectional study on a random sample of 1843 schoolchildren aged 12 and 15 from Galicia (northwest of Spain). Self-administered questionnaire and dental clinical examination were performed to obtain information about oral health habits, dental caries and oral hygiene.

Critical anatomic region of nasopalatine canal based on tridimensional analysis: cone beam computed tomography.

The study aim of this was to define the critical anatomic region of the premaxilla by evaluating dimensions of nasopalatine canal, buccal bone plate (BBP) and palatal bone plate (PBP). 230 CBCTs were selected with both, one or no upper central incisors present (+/+, -/+, -/-) and periodontal condition was evaluated. T-student test, ANOVA, Pearson's correlation and a multivariant-linear regression model (MLRM) were used.
