SANCHEZ-PEREZ, Leonor et al. Baseline risk factors for caries in elementary school aged children. Bol. Med. Hosp. Infant. Mex. [online]. 2005, vol.62, n.1, pp. 33-44. ISSN 1665-1146.

Introduction. The objective of this report is to present the initial associations between age and gender and the biological risk factors at the baseline of a diagnostic model to predict the risk for caries. Material and methods. The following indicators were registered in 110 elementary school children between 6-7 years of age, who attended to 2 public schools in Mexico City: dental (morphology, caries indexes and active caries lesions); salivary (stimulated flow rate and Snyder test); and bacteriological (Streptococcus mutans and Lactobacillus counts in plaque and saliva). Results. Caries experience was associated with dental morphology, Snyder test and with 3 of the bacterial indicators (ANOVA). When the biological risk factors were analyzed by the cut off point for risk, the following variables were identified: salivary S. mutans counts (0.96), Snyder test (0.61) and history of caries (0.58) as highest. Three models of ANOVA were used with/without weighted immutable risk factors, identifying that the indicators: morphology, active lesions and salivary Lactobacillus counts as the factors significantly associated with the caries experience in the 3 models. Conclusion. The model that best explains the risk for caries is the 1 that weighted for gender R2 62%.
