Influencia del sellado marginal en prótesis fijas y estado de salud periodontal, clínica UCSG semestre A 2017 - B 2018.

Abstract

INTRODUCTION: Periodontal disease as an inflammatory pathology, is based on specific concepts studied in the literature such as: its infectious etiology and the chronic response by the host. One of the triggers of periodontal disease in patients with fixed prostheses is poor marginal sealing, which occurs in prostheses at the time of cementing; that is, we must achieve adequate retention, resistance and sealing at the interface between the restorative material and the support tooth, being one of the determining factors for the long-term permanence of the fixed prosthesis in the mouth and thus not having problems, both in the restoration as in the periodontium. OBJECTIVE: To identify the influence of the marginal sealing of fixed prostheses on the periodontal health status of patients treated in the dental clinic of the UCSG from semester A2017 to B2018. MATERIALS AND METHODS: It is a retrospective, observational descriptive, and cross-sectional clinical investigation since the variables will be measured once; with a sample of 110 patients treated in semesters A2017- B2018 in the Fixed, Restorative and Comprehensive Clinic chambers. We will proceed to observe variables such as: marginal sealing, oral hygiene, dental preparation, among others; in each of the patients. The results will be measurable through statistical data. RESULTS: It was observed that of the 110 (100%) patients evaluated, the majority were women with a frequency of 64.55%; unlike men who only occupied 35.45% of cases. The periodontal health of these patients in dental preparations is mostly in Grade 0, with a percentage of 59.09%; which means that the gum is healthy, without any inflammation or bleeding from the catheter. Of the dental preparations, Yuxtagingival was most frequently found (80), in a percentage of 72.73%; followed by supragingival (19), in a percentage of 17.27% of cases; The retention rate that presented with the highest incidence that was presented was Grade 2 with 46%; which means that the margin is not over extended or closed, but that there is a slight discrepancy between the tooth and the fixed prosthesis. CONCLUSION: In conclusion we can say that there is a relationship between periodontal health status and the presence of fixed prostheses poorly adapted or over contoured. Therefore, periodontal controls should be carried out before, during and after any rehabilitation treatment, in order to achieve and guarantee its success, functionality, longevity and therefore well-being for the patient.
