The epidemiological aspects of endodontics in comparison with the epidemiology of caries have been insufficiently studied, especially in our country. Aim. The purpose of this work is to assess the endodontic status of patients depending on the level of dental caries resistance. Material and methods. We, based on clinical observations, put forward an assumption about the relationship between the frequency and nature of complications of caries and the level of their resistance to disease according to Nedosenko V.B. The subject of our study was to test this assumption on factual material. The materials of the study were medical documents of 292 patients treated for diseases of the periapical tissues. Orthopantomograms of these patients were analyzed. Methods of statistical analysis were used for assessments and conclusions: Kullback's information statistics and the difference method. Results. When considering the relationship between complications of caries and levels of resistance, an inverse relationship was found, that is, among persons with an average level of dental resistance to caries, the frequency of complicated forms is much lower than among persons with low and very low (p < 0.001). Most often, diseases of the periapical tissues with a destructive process in the periodontium occurred in persons with a low level of resistance. The frequency of diagnostics of destructive periodontitis arising without endodontic treatment and periodontitis arising after endodontic treatment in patients with an average level of resistance is lower than in patients with a low level of resistance. Discussions. The lower the level of resistance of teeth to caries, the more often untreated periodontitis is detected, more often destructive periodontitis occurs as an outcome of endodontic treatment for pulpitis. Conclusions. The data we have obtained allow us to increase the effectiveness of caries treatment, taking into account the level of tooth resistance.
The problem of oncological and precancerous diseases of the oral mucosa is urgent, because the prevalence of these diseases is high, as well as malignant neoplasms of this localization are among the most aggressive and difficult to treat human neoplasms, characterized by a high percentage of mortality. These facts determine the increased importance of primary prevention of precancerous and cancerous diseases, the purpose of which is to identify and eliminate predictive factors of the development of these pathologies. Objective of the study is to conduct a systematic analysis of modern Russian and foreign literary sources in the aspect of predictive factors of the occurrence of precancerous and cancerous diseases of the red border of the lips and oral mucosa and their main mechanisms. Methodology. The research is based on the search and analysis of modern Russian and foreign original sources on the topic in the databases eLibrary, Pubmed, Crossref. Results. The development of precancerous and oncological diseases is a complex multifactorial process that proceeds under the influence of a number of prognostic factors that have both isolated and synergistic effects on the human body at the local or general level. Conclusion. We have analyzed the scientific literature, which indicates a significant contribution of a wide range of modifiable and unmodifiable factors in the development of precancerous and oncological processes. Identification and correction of probable risk factors for the occurrence of precancerous and oncological diseases of the oral mucosa can help prevent the development of these diseases.
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.
