Main reason of the origin of combined disorders endodont and parodont supporting teeth in the system of functioning fixed designs

AIM. To determine the etiological factors responsible for the development and progression of combined endodontic-periodontal lesions in abutment teeth supporting functioning fixed prosthetic restorations. MATERIALS AND METHODS. A total of 88 patients with combined endodontic-periodontal involvement of abutment teeth under functioning fixed prosthetic constructions were clinically examined. The etiological structure of these complex lesions was assessed through a comprehensive approach that included clinical, paraclinical, and statistical methods of investigation. RESULTS. Analysis revealed several predisposing factors strongly associated with combined endodontic-periodontal lesions beneath fixed prostheses. Deep periodontal pockets exceeding 5 mm, together with chronic destructive periapical processes and advanced alveolar bone resorption, were the most critical contributors. In most cases, lesions were classified as granulomatous periodontitis with a diameter greater than 5 mm. These were accompanied by disturbances in periodontal microcirculation, further accelerating tissue breakdown. The identification of such factors underscores their practical relevance for clinical decision-making in prosthodontics. CONCLUSIONS. Combined endodontic-periodontal lesions are characterized by diffuse inflammatory destruction of alveolar bone tissue in the projection area of fixed prosthetic constructions. The pathological process is accompanied by a mixed type of resorption involving both interproximal and interradicular septa of teeth serving as abutments.
