Dental Caries Spectrum in Brazilian Publicschoolchildren and Adolescents
Objectives: Dental caries remains an important public health problem with increase in adolescent period of life. The Caries Assessment Spectrum and Treatment (CAST) is a new system to assess dental caries epidemiology and few studies were reported with its methodology. The aim of this study was to assess dental caries spectrum profile in Brazilian children and adolescent public schoolers.
Methods: A cross-sectional study was carried out in two public schools in Brazil examining permanent teeth of children and adolescents. The dental caries was assessed by Caries Assessment Spectrum and Treatment (CAST) and results distributed by disease status (healthy/codes 0-2; pre-morbidity/code 3; morbidity/code 4-5; severe morbidity/codes 6-7; mortality/code 8) and severity CASTF1 (mild; moderate; severe). The CAST data was described by age groups (8-9; 10-11; 12-13; 14-15; 16-17; 18-19 years-old). Qui-square test was used to find association between variables.
Results: A total of 598 students participated. The highest prevalence of healthy students was (50.00%), for caries pre-morbidity (23.53%) and severe morbidity (11.76%), at age of 8-9. The morbidity (46.15%), mortality (7.69%) and mean CAST-F1 (7.69%) was higher at 18-19 years-old. The highest severity scores (CAST-F1) was 39.22% (Mild; 16-17 years-old), for Moderate dental caries was at age 18-19 (30.77%) and for Severe (11.76%; 8-9 years-old). Associations between age and CAST system were found (p<0.01).
Conclusions: Dental caries spectrum in these Brazilian publicschoolchidren and adolescents increased from the group 8-9 to 18-19, and CAST system is an important new tool for dental caries epidemiology studies in children and adolescents.
