VALLEJOS-SANCHEZ, Ana Alicia et al. Caries severity using a criterion according to size of lesion among Mexican schoolchildren. Rev. Univ. Ind. Santander. Salud [online]. 2015, vol.47, n.3, pp.291-299. ISSN 0121-0807.

Objective: To determine the severity of caries (lesion size) and associated variables in Mexican schoolchildren. Material and Methods: A cross-sectional study was conducted in 1373 schoolchildren 6-12 years old enrolled in public schools in Campeche, Mexico. Questionnaires were distributed to determine demographic, socioeconomic and behavioral variables. Dental examination was performed to each child to establish the size of caries lesions according "Criterion of carious lesion magnitude" index and to allocate according to the number of lesions present to one of four risk groups for developing cavities wherein the first group represents the least affected. A multivariate multinomial logistic regression model was generated. Results: Caries risk groups were distributed as follows: 598 (43.6%) were in group 1; 261 (19.0%) were assigned to group 2; 316 (23.0%) were in group 3; and 198 (14.4%) in group 4. Comparing with the least affected group by carious lesions, associated variables for severity in the multivariate model were "Risk Group 2": age, sex and developmental enamel defects; "Risk Group 3": dental care in the past year, mother's attitude toward oral health and developmental enamel defects; "Risk Group 4": age, dental care in the past year, mother's attitude toward oral health and developmental enamel defects. Conclusion: Severity of decay is influenced by demographic, behavioral and clinical variables.

Keywords : oral health; dental caries; patient acuity; dental enamel.
