ABSTRACT
Aim: This study analyzed and compared the experience of dental caries in 300 children aged 0 to 48 months, who were participants and non-participants of a preventive program Dentistry for babies, as well as the correlation between assiduity of dental visits and experience of dental caries. Methods: The subjects were randomly selected and divided into two groups: G1 Nonparticipant children of the Program (n=100) and G2 Participant Children of the Program (n=200). Each group was subdivided in two subgroups: 0-24 months and 25-48 months. The collecteddata from G2 were analyzed, relating the variation of the dmft index (dmft refers to primary teeth: d = decayed, m = missing/extracted due to caries, f = filled, t = teeth) (C) and dental caries prevalence (P) with the influence of assiduity factor in each subgroup. To collect data, clinical examinations were performed using tactile and visual criteria by a single calibrated examiner.The data were statistically analyzed using the paired t-test, Mann-Whitney and Chi-Squared tests (p<0.05). Results: It was found that prevalence and dmft index were statistically significant (P=0.0001) with the greatest values observed in G1 (p=0.0001). The values were: PG1 (73%), PG2 (22%), CG1 (3.45±3.84), CG2 (0.66±1.57). Assiduity was significant in G2 (p=0.0001). The values observed were: P-Assiduous (2%), P-Non-assiduous (42%), C-Assiduous (0.04±0.31), and C-Non-assiduous (1.29±2.01). Conclusions: The participation in the program had a positive influence on the oral health of babies. Complete assiduity to the program resulted in the lowest rates and prevalence of dental caries.
