Abstract

Aim. Investigation of the prevalence and severity of dental diseases of seafarers of the Black Sea Russian Fleet, as well as the need for various types of dental care. Methods. Thorough dental examination of 785 mariners aged 18 to 40 years was performed. Group 1 consisted of 510 conscripts aged 18-27 years, group 2 - 275 military contract personnel aged 18-40 years. A thorough dental examination was performed using mouth mirror and probe, as well as the graduated periodontal probe. Dental caries extension and DMF (decayed-missing-filled) index were determined. Evaluation of periodontium was carried out according to the CPITN index (Community Periodontal Index of Treatment Needs), hygiene indices (Fedorov, Y.A., Volodkina V.V., 1971) and Sulcus Bleeding Index (SBI, Мuhlemann, Son, 1971). Results. Investigation of oral disease prevalence among seafarers of the Black Sea Russian Fleet showed its increase during the last twenty years. Particularly, dental caries prevalence among conscripts and military contract personnel of Black Sea Fleet reached 97.64±0.36% and 99.63±0.36%, respectively (DMF 8.85±1.25 and 13.30±2.05, respectively), and prevalence of chronic generalized periodontitis was 10.70±1.37% and 18.30±2.33%, respectively (p
