Dental caries lesions and impact on quality of life in adolescents living in urban and rural areas. A case study.

The concept of quality of life (QoL) developed from early studies on subjective wellbeing and satisfaction with life, interpreted as resulting from living conditions, and recognized by means of objective indicators. Indicators have been developed and validated to measure the relationship between quality of life and health Aim: To determine, during an Educational Social Practice, the association between presence of dental caries lesions and its impact on quality of life of adolescents living in rural and urban areas in Argentina. Materials and Method: This was an observational cross-sectional study in (a) a rural area (Tres Isletas; Chaco Province/Schools No. 601 and 477) and (b) an urban area (Villa Soldati; Buenos Aires City/Nuestra Sra. Fátima School). The sample included 40 students from the urban area (UG) and 30 from the rural area (RG). A calibrated researcher (Kappa 0.80) collected the survey data and performed the clinical examinations. The following were recorded: (a) sociodemographic distribution in terms of age and gender; (b) presence of dental biofilm according to Silness and Löe; caries lesions according to ICDAS II /INTCy criteria, and (d) DMFT, total and per component. Quality of life was assessed using the CPQ 11-14r. Statistical processing included calculation of frequency distribution of the variables (X± DS), and chi-square and Mann-Whitney tests to calculate association and comparisons between groups. Results: The sample included 47 girls (67.1%) and 23 boys (32.9%). Distribution according to sex and age did not differ significantly between sites (UG:12.9 years ± 0.5 and RG:11.8 years ±1.1). No significant difference was found between sites for a) plaque biofilm (p=0.759); b) DMFT, total value and per component, or c) individual and grouped ICDAS scores. Percentage analysis of the CPQr 1-14 scores showed significant differences between groups for questionnaire total scores (26.9% ± 2.2 in UG and 4.1% ± 0.8 in RG) and for the different domains. Conclusion: Perceived impact on quality of life caused by dental caries lesions was significantly higher in urban than the rural group, although neither the dental caries process nor the amount of biofilm differed significantly between groups.
