Risk/prevention indicators for the prevalence of dental caries in schoolchildren: results from the Italian OHSAR Survey.

The Italian Oral Health of Schoolchildren of the Abruzzo Region (OHSAR) Survey was designed to assess indicators associated with the prevalence of caries in both the primary and permanent dentitions in the same schoolchildren, and it comprised a representative sample of 5,938 7-, 9- and 11-year-old schoolchildren from three provinces within the region of Abruzzo, Italy, a low fluoride concentration area. Gender, age, geographic location, socioeconomic level, dietary and oral hygiene habits, and the use of F supplements were all considered as indicators. The subsequent multivariate analyses showed that the socioeconomic level, snack consumption frequency, consumption of sweets and the use of F supplements were mostly associated with caries prevalence in both dentitions. Other indicators, such as gender, age, geographic location, between-meal snack consumption frequency, consumption of sweet drinks, toothbrushing frequency and onset of regular toothbrushing habits also showed some significant associations with dental caries across the age groups and/or dentitions. Of interest, the consumption of commercial bottled mineral water was also seen to be a preventive indicator for dental caries of the primary dentition, particularly in the 7-year-old group. The consumption of sweet snacks, use of interdental floss and kind of toothbrush mainly used (manual or electric) did not show any relevant association with the outcomes. The strong effect of the geographic location, socioeconomical level and the preventive effects of commercial bottled mineral water are worth further investigation.
