Introduction. A research was conducted of the features of the structural and functional state of bone tissue in patients with generalized periodontitis with rheumatoid arthritis who live in different anthropogenically loaded areas. Aim. The aim of the research is to assess the bone tissue mineral density according to the indicators of densitometric researches and the level of a marker of bone metabolism in generalized periodontitis of I and II degree of severity. Material and methods. We examined 105 patients with GP of the I and II degree of severity, among whom were patients with rheumatoid arthritis who live in environmentally favorable and unfavorable areas. Peculiarities of the structural and functional state of bone tissue were assessed using an ultrasonic densitometer Sunlight Mini Omni TM and the level of a marker of bone tissue resorption of deoxypyridinoline in urine. Results. Patients with generalized periodontitis with rheumatoid arthritis who live in environmentally unfavorable areas, found the largest number of people with signs of osteopenia, osteoporosis and elevated levels of deoxypyridinoline. In particular, in generalized periodontitis of the II degree of severity with osteopenia – 14 people (48.27%), with osteoporosis – 9 people (31%), the level of deoxypyridinoline determined in women was 12.03 ± 0.16 n/mol, which in 2.2 times significantly higher than the group of healthy (p < 0.001). Conclusions. According to densitometric parameters and the level of deoxypyridinoline in the urine, the acceleration of bone tissue resorption in patients with generalized periodontitis of the II degree of severity with rheumatoid arthritis who live in environmentally unfavorable areas was established.
The aim of the work was to compare the condition of periodontal tissues in patients with rheumatoid arthritis who live in ecologically favorable and environmentally unfavorable territories. There was performed a dental examination of 21 patients with rheumatoid arthritis who live in environmentally favorable territories and of 21 patients with rheumatoid arthritis who live in environmentally unfavorable areas. There was given the index evaluation of the condition of periodontal tissues, the level of oral hygiene. It has been determined that the course of generalized periodontitis in patients with rheumatoid arthritis who live in ecologically contaminated territories is more difficult than in a group of patients who live in environmentally favorable territories.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
