Prevalence and caries-related risk factors in schoolchildren of 12- and 15-year-old: A cross-sectional study
BMC Oral Health Jun 23, 2019
Obregón-Rodríguez N, et al. - Among 1,843 schoolchildren aged 12 and 15, researchers evaluated the prevalence and severity of caries and examined the related risk factors. To obtain information about oral health habits, dental caries and oral hygiene, self-administered questionnaire and dental clinical examination were performed. This cross-sectional study demonstrated that risk factors of dental caries showed differences in schoolchildren of 12- and 15-year-old. In the frequency of toothbrushing and dental plaque, the strongest evidence relating to caries was found in the 12-year-old group. In 15-year old group, electric toothbrush, time since the last visit to the dentist and type of dental care (public/private) had a stronger connection with dental caries. The respective findings for 12- and 15-years-old were as follows: decayed, missing, filled teeth index both for permanent and temporary dentition (DMFT/dmft) of 0.89 and 1.38, respectively; caries prevalence 39.6% and 51.7%, respectively. The prevalence of caries and mean DMFT/dmft increased from 12 to 15 years of age, despite improvement in oral hygiene at age 15. According to WHO Oral Health Guidance for 2020, DMFT/dmft and caries prevalence were low, but there were inequalities among the population, and the objectives proposed by the Alliance for a Cavity-Free Future are still far from being achieved.
