Prevalence of Dental Pain in Schoolchildren Aged 6 to 12 Years and Clinical, Sociodemographic, and Socioeconomic Risk Indicators: A Multicenter Study of Four Mexican Cities.

Abstract

Background: Dental pain is a significant public health issue globally and in Mexico, with substantial negative impacts on affected individuals. Objective: The objective of this study was to evaluate the prevalence of dental pain and its association with clinical, sociodemographic, and socioeconomic risk indicators in schoolchildren aged 6 to 12 years in four cities in Mexico. Material and Methods: A cross-sectional study was conducted on 500 children attending public schools in the cities of Pachuca, Tepatitlán, Toluca, and San Luis Potosí. A questionnaire was applied, and a clinical examination was performed on the schoolchildren. Self-reported dental pain within the 12 months preceding the study, categorized as 0 (no pain) and 1 (pain), was used as the dependent variable. For the statistical analysis, the Stata program was used, where a multivariate binary logistic regression model was applied. Results: The mean age was 8.92 ± 1.99 years; 50% were girls. The prevalence of dental pain was 34.0%. Independent variables associated (p < 0.05) with the experience of dental pain were as follows: age (OR = 0.81), having a car at home (OR = 0.77), a lower socioeconomic position (OR = 2.03), curative or specialized dental care (OR = 8.40), and self-reported dental and/or gingival disease (OR = 5.39). Conclusions: Dental pain is a significant health problem in schoolchildren aged 6 to 12 years in Mexico, with a prevalence of 34% in this study. Sociodemographic and socioeconomic factors, as well as clinical indicators, play an important role in the experience of dental pain. Inequalities in oral health were observed. There is a need for public health interventions to reduce this problem in vulnerable populations.
