Introduction: The prevalence and extent of den- tal caries have declined significantly since the late 1970s in many countries. However, caries become an increasing problem for pre-school children. Early car- ies damage is beneath the surface with a surface white lesion d1 and demineralisation to enamel cavitation.
Objective: Clinical-statistical study of caries of temporary teeth in 4-6 year old children, calculating the incidence of dental caries on teeth and surfaces.
Material and methods: Subject of research - Diag- nosis and treatment of cavity caries of temporary teeth through. Object of investigation - tooth decay of chil- dren from 4 to 6 years of age. Criteria for inclusion of children: From 4 to 6 year old children - healthy, ac- companied and cared for by parents without system- ic, gingival and mucosal diseases. Observation Units: Temporary teeth, dft, dfs, active and inactive caries le- sions at level d1, d2, d3 + d4. The study is realized in the Faculty of Dental Medicine - Varna. The study is authorized by the Ethics Committee of the Scientific Research at the Medical University - Varna. For the statistical analysis of the data, a statistic specialization package STATISTICA 10.0 was used.
Results: The mean incidence of caries in individu- al age groups shows that children with the highest in- cidence of caries are 6 years old (dmft = 6,01). Surface cavity results show that caries of 1 and 2 surfaces pre- dominate (23.75%).
Conclusions: 1. The epidemic dynamics mark a gradual increase with age. 2. Reverse lesions predom- inate in the contingent; Any age of 4, 5 or 6 years is suitable for non-invasive treatment. 3. The incidence of initial carious lesions is higher than the incidence of cavitation caries lesions and increases with age.
