Prevalence of Caries on Individual Tooth Surfaces and its Distribution by Age and Gender in University Clinic Patients

Objectives: The objectives of the present study were to assess the prevalence rate of caries on individual permanent tooth surfaces, and to compare individual tooth surface caries rates among gender and age groups.

Methods: Without drying the teeth, examinations were performed with dental mirrors and blunt, sickle-shaped explorers under a dental chair light, according to WHO recommendations.

Results: Caries distribution was higher in the maxillary jaw (62.4%) than in the mandibular jaw (37.6%). Except molars, approximal surfaces of all teeth demonstrated the highest caries rates, ranging from 58.5% to 77.5%. Occlusal fissures on the first and second molars contributed most significantly to caries frequency, from 52.7% to 66.3%. Females (59.1%) showed a higher incidence of caries than males (40.9%). Approximal surfaces of incisors, canines, premolars and occlusal fissure sites in molars showed the highest caries rates in both sexes. Caries were most common among individuals aged 17 to 25 years. Approximal surfaces of incisors, canines, premolars and occlusal surfaces in molars had the highest caries rates in all age groups, except for individuals older than 65 years of age.

Conclusions: Gender and age do not affect the prevalence of caries on teeth sites. In addition, more caries are experienced in younger age groups, and their incidence decreases as age increases. (Eur J Dent 2010;4:270-279)
