To assess the prevalence and severity of caries in 12- 15-year-old schoolchildren, to analyse related risk factors. We conducted a cross-sectional study on random sample 1843 schoolchildren aged 12 15 from Galicia (northwest Spain). Self-administered questionnaire dental clinical examination were performed obtain information about oral health habits, hygiene. A logistic regression model including dental-caries-related variables was generated for each age group. The respective findings 15-years-old as follows: decayed, missing, filled teeth index both permanent temporary dentition (DMFT/dmft) 0.89 (95% CI, 0.87–0.91) 1.38 1.33–1.43), respectively; 39.6% 36.3–42.9) 51.7% 48.0–55.4), respectively. In 12-year-old group, individuals who occasionally, never or hardly ever brushed their had higher values (OR = 1.83, 95% CI 1.07–3.15, OR 9.14, CI1.63–51.17, respectively). Also, presence plaque more than 1/3 gingival statistically associated with an increase 2.03; 1.11–3.70), living rural environment factor 1.3; CI,1.02–1.80). found when brushing once day 1.61; CI,1.03–2.50), among visited private clinics 1.77; 1.17–2.66), while electric toothbrush lower 0.50; 0.29–0.86). This revealed that factors showed differences 15-year-old. Strongest evidence group frequency toothbrushing plaque. 15-year old toothbrush, time since last visit dentist type care (public/private) stronger association caries. Caries mean DMFT/dmft increased 15-year-old, spite improvement hygiene at 15.
