According to the researches by national authors, the variability in the number of children and adolescents with small bounded edentulous spaces is noted. It depends on geographical area of residence, level of the region urbanization, the state of dental care. The latter determines the need to study the prevalence of small bounded edentulous spaces in school age individuals in a particular region in order to plan and optimize their prosthetic rehabilitation. The foregoing justifies the objective of our research.
Materials and methods of the research. Small bounded edentulous spaces in 2360 individuals of school age living in Lviv were the study subject. Study object involved determination of their incidence depending on age and gender, and main reasons for their occurrence.
Results of the research and their discussion. The incidenceofsmall bounded edentulous spaces among school children in Lviv was found to range on average from 8.90% in girls to 10.53% in boys. The increase in the number of patients with the studied pathology in the age range from 9 to 17 years of age in both gender groups was proven. Moreover, these indices were higher in boys in all age groups in comparison with girls. Small bounded edentulous spaces were found to be diagnosed in the lateral areas of both jaws by 2.5 times more often than in the frontal ones in all examined patients. The main reason for premature loss of permanent teeth was the ineffectiveness of conservative treatment or its absence.
Conclusions. The results of the research indicated that the incidence of small bounded edentulous spaces among school children in Lviv was significant, in the range of 10%. It had a tendency to increase with age substantiating the need for prosthetic rehabilitation of school age individuals.
