Abstract:

Aim: The aims of this research were to determine the epidemiological profile of dental caries in 4 to 6-year-old preschool children with two different caries indices-the standard df-t and Nyvad???s caries diagnostic criteria.

Materials & Methods: A total of 58 pre-school children with 1100 teeth in the age group of four to six years were selected for the study from among who applied to Marmara University, Dental School and Pediatric Dentistry clinic. Children teeth were cleaned and dried with cotton rolls and chip blower. The dental caries examinations were conducted under standardized conditions using plane mouth mirrors and explorers with the help of artificial illumination. The diagnostic criteria used were df-t and Nyvads's caries diagnostic criteria. Each tooth of all deciduous teeth was classified according to one of the following criteria: 0=sound; 1=active, surface intact; 2=active, surface discontinuity; 3=active, cavity; 4=inactive, surface intact; 5=inactive, surface discontinuity; 6=inactive, cavity; 7=filled; 8=filled with inactive lesion; 9=filled with active lesion; X=extracted.

Results: The mean df-t was 10.8 (�4.69). Most of the teeth that caries experience consisted of tooth with active lesions (80.7%), of which 9.6% were non-cavitated. The mean number of teeth with non-cavitated inactive lesions was 4.27%. The mean df-t constituted 10.8; the majority of all second molars were affected (86.22%), followed by the first molars (83.11%).

Conclusions: Prevalence of caries was high indicating that the population studied had a high disease rate. The results obtained with the more detailed Nyvad???s caries diagnostic criteria were higher than the ones obtained with the standard df-t index for teeth.
