The guided tissue regeneration (GTR) is one of the basic ways for alveolar ridge reconstruction in the implantology and periodontology. It has been using for more than 30 years and allows to get stable and predictable outcomes. However, quality and volume obtained tissues depends on a wide range the local, systemic and technological features which have to be taken into account. Only this approach let us achieve predictable and stable outcomes of the therapy. In the article two clinical cases of GTR are depicted in two different applications of the dermal matrix Collost usage as a collagen barrier membrane.
Relevance of the research topic. There is a relationship between dental status of a pregnant woman and time of gestation. It is known that oral condition is changing depending on the trimester of pregnancy.Purpose. The aim of the research was to study and compare the clinical condition of oral cavity in this group of patients, depending on the gestation period.Methods and materials. For this purpose 110 pregnant women with diabetes mellitus were examined with using basic and additional examination methods.Results. Pregnant women in 2 gestation period have the worst condition of oral cavity.Summary. Analysis of results of the study allows us to determine the most critical phase during pregnancy and in future to promote normalization of oral cavity precisely in this period.
Relevance. Resistance of periodontal diseases to conservative therapy may constitute up to 7% of all clinical cases and may be due to specific pathogens. Active infection caused by Candida spp. and bacterial infection (formerly known as mycosis) caused by Actinomyces spp. are possible clinical options. Both the absence of described specific clinical manifestations and pathogen variety, ability to morphological transformation and similar unconventional approaches to microbiological diagnosis determine the continuity of the pathological process. At the same time, both the available scientific literature and our clinical work evidenced the detection of a diagnostically significant quantity of Candida spp. and Actinomyces spp. in pockets of patients with a worse response to periodontal therapy. However, most available studies used non-morphological diagnostic methods, which are hard to interpret assess ing the effect of the infectious process on the course of periodontitis. Possible options include the following: from significant etiological reasons, aggravating factors, background process or marker of systemic or local disorders to the dysbiosis caused by antibacterial therapy.Propose. To draw the attention of dental practitioners to the peculiarities of the course of the infectious process in patients with resistance to periodontal therapy.Conclusion. The paper presents specific characteristics of differential diagnosis, risk group assessment, comprehensive approach to local and systemic therapy based on the data from modern literature, our analytics and particular clinical cases.
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.
