OBJECTIVE: To study the dental status of patients depending on the presence of precancerous diseases of the oral mucosa. MATERIAL AND METHODS: For the first time in the Ryazan region 1857 people aged 18 to 89 years were examined. To assess the dental status of patients the CFE (DMFT) index and the OHI-S hygienic index (Green, Vermillion, 1964) were used, the presence of orthopedic structures was noted. RESULTS: During the examination 1700 (92.34%) patients did not have diseases of the oral mucosa, while 141 (7.66%) had precancerous diseases: leukoplakia, lichen planus, papilloma and papillomatosis of the palate. The highest value of the CFE index was found in women aged 60-74 years, as well as in men and women aged 75-89 years, both among patients with and without precancerous diseases of oral mucosa. When analyzing the data of individual components of the CFE index of patients with precancerous diseases of the oral mucosa, the predominant C index (caries) was identified in the group of men aged 45-59 years, a high value of the F index (filling) was obtained among women aged 18-44 years. There were equally many extracted teeth (an indicator E of the CFE index) in men and women aged 75-89 years, both in the group of patients with precancerous diseases of the oral mucosa and in the group of patients without them. A significantly higher number of orthopedic structures were found in patients diagnosed with leukoplakia (44 people - 61.11%). A satisfactory level of hygiene was diagnosed in all age groups of patients with both precancerous diseases of the oral mucosa and healthy patients. CONCLUSION: Based on the results of the study of the dental status, the absence of differences in the CFE index and its individual components, the OHI-S index, and the number of orthopedic structures between groups of patients with and without precancerous diseases of the oral mucosa was obtained and statistically proven. A statistically significant higher number of orthopedic structures was shown in patients diagnosed with leukoplakia in comparison with the group of patients without pathological changes of the oral mucosa.
