Factors associated with caries: a survey of students from southern Brazil

Abstract

Objective:To describe the factors associated with dental caries among students from Santa Cruz do Sul, Rio Grande do Sul, Brazil.Methods:A cross-sectional study was conducted in a random sample of 623 students of both genders, aged 10-17 years old. Tooth decay was performed using the index of the World Health Organization (1997), DMFT (permanent dentition) that expresses the sum of decayed, missing and filled teeth per person. The maternal educational level was rated using criteria of the Brazilian Association of Market Research Companies. The remaining variables were obtained by a structured questionnaire. Poisson regression analysis was used to test the association between variables using robust models and a subsequently adjusted model. Data were expressed as prevalence ratio (PR).Results:Multivariate analysis identified the following factors related to the experience of dental caries: residence in rural municipalities (PR: 1.15; 95%CI: 1.0-1.3), attending a city school (PR: 3.30; 95%CI: 1.1-9.4) or a state school (PR: 3.40; 95%CI: 1.1-9.6); and having an illiterate mother or a mother that only attended up to the 4th year of school (PR: 1.67; 95%CI: 1.1-2.4) or high school (PR: 1.54; 95%CI: 1.1-2.2).Conclusions:The presence of caries in students in southern Brazil was associated with residence in rural areas, mother with little education and attendance to a public school.

Dental Anxiety Levels and Affecting Factors in 7-14 Years Old Children

“…In addition, it was determined that the mothers' working affected the DMFT point average of children. Borges et al (2015) in study of 623 students aged 10-17 in Brazil reported a significant difference in the percentage of children whose mothers completed their 4-year educational life [24]. In our study, the difference between the educational background of parents and DMFT point average of children was not significant.…”

“…55.9% of the children were consuming junk food every day as show in Table 6.The DMFT average of children who consumed junk food every day was very high found as 5.11 ± 3.67 in Table 6.In Gökalp and Doğan's study (2004),which examined to treatment needs of 5-12 and 15 years old children and 35-44 years old and 65-74 years old adult (n = 7833), it found that tooth decay rate of 5 years old was 69.8%, 12 years old was 61.1% , and 15 years of age was 66.4% [22]. Jessri et al (2013) found DMFT mean of 2.51 ± 2.14 in school children aged 9-13 in Tehran (n = 1271) [23] and Borges et al (2016) in Brazil with 623 students in the 10-17 age group reported an average DMFT of 2.5 [24]. Koçanlı et al (2014) found a positive correlation between the frequency of dietary food intake and child caries index values in their study with 300 children aged 7-13 years [25].…”
