Caries distribution by teeth groups among 12-18-year-old children in Varna

Milena Georgieva, Radosveta Andreeva


Introduction: Dental caries is a complex disease, caused by physiological imbalance between the saliva in the oral cavity and the dental biofilm (microbial cells organized in extracellular matrix, which use the possible nutrients from the oral environment in their favor). The processes of de- and re-mineralization occur in the oral cavity daily, which may lead to cavitation, recovery or preservation of the balance in the oral environment.

Aim: The aim of this article is to show the results of the caries distribution by different teeth groups among 12-18-year-olds in Varna.

Materials and Methods: We did registration of the dental status of different groups of teeth for 12-18-year-old children, using the DMFT index.

Results: Dental caries affects the permanent molars the most - 71% of the clinical cases. In 20% of the children a premolar dental caries can be observed and barely 9% is the share of the caries on the incisors. Tooth decay on the canines is not established. It is reported that the intensity of the caries on the permanent molars is relatively high - 3.93±2.3. The frequency of caries distribution on these teeth groups is not even.

Conclusion: In Central, Eastern Europe and the Middle East the distribution of tooth decay among adolescents remains high. This is confirmed by data for caries intensity in Bulgaria, Varna, in particular among 12-18-year-old children. Extremely high is the caries prevalence in the permanent molars in these children - 71%.
