Abstract


Objective: The aim of this study was to evaluate the posterior approximal caries in primary teeth, show improvement in clinical diagnosis with the use of radiography bitewing and explore associations with demographic, socioeconomic, clinical and reporting of frequency of brushing and flossing.
Method: Fifty children (5 to 8 years old), attending in the Pediatric Clinic of the College of Dentistry– Federal University of Pelotas, were clinically examined and a bilateral bitewing radiographic was taken by one previously trained operator with a standard technique. Demographic data and information on oral hygiene were collected from an interview answered by the children’s mothers. The diagnostic assessment from the radiographic images was conducted by 2 calibrated examiners (Kappa 0.85), following Rolla et al., 1996 modified criteria. Results were analyzed with descriptive statistics and t test (α=0.05).
Results: Posterior approximal caries identification increased with the bitewing examination, from 5.48 to 6.14 (p=0.001). From the 25% lesions detected with the radiographic exam, 84.6% were enamel lesions and 10.8% were dentine lesions. Posterior approximal caries in primary teeth showed statistically significant association with: age range (increasing from 4.29 at 5-6 years to 7.48 at 7-8 years, p=0.005); first permanent molars eruption stage (p=0.018); the gingival bleeding (p=0.040); and with mother´s educational level (p=0.049). Associations with gender, family income, frequency of brushing and use of dental floss were not observed.
Conclusion: Even considering the difficulties of the technique, bitewing radiographs improve the clinical diagnosis of posterior approximal carious lesions in children.
