Abstract
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.

IntroductionThe interaction between acidogenic microorganisms, sugar attacks, and host susceptibility are responsible for the development of new carious lesions and the progression of existing ones [3]
Dental caries are the most prevalent non-transmissible disease in humans [1]
We can conclude that the intake of sweets and soft drinks, toothbrushing frequency, the presence of caries in TT, and molar incisor hypomineralization (MIH) in permanent teeth (PT) were the best predictors of the occurrence of caries in PT and permanent first molar (PFM)
Summary
The interaction between acidogenic microorganisms, sugar attacks, and host susceptibility are responsible for the development of new carious lesions and the progression of existing ones [3]. Other factors, such as toothbrushing with a fluoridated toothpaste, or behavioral, social, and cultural factors influence the progression of caries both positively and negatively [4,5]. Epidemiological studies have facilitated the determination of the prevalence, incidence, and distribution of dental caries in different countries and regions, as well as the evaluation of the impact of preventive and therapeutic measures applied in oral public health [6,7,8]. National and regional epidemiological studies carried out in Spain have demonstrated that caries prevalence in temporary teeth (TT) at 5–6 years of age has increased in the last 5 years, while in permanent teeth (PT) a noticeable reduction at 12 and 15 years of age has been noted in the last 20 years [9,10]
