Background: This study was conducted to assess the relationship between fixed prosthesis and gingival problems. Material and methods: The study included overall 100 subjects undergoing fixed prosthesis. The study included subjects without any periodontal pathology as well as patients requiring fixed prostheses. Patients with systemic diseases, complete missing teeth, pregnant women as well as smokers were excluded from the study. The Community Periodontal Index (CPI index) and the probe transparency method (TRAN), two validated assessment tools, were used to evaluate patients before and a year after prosthetic rehabilitation, taking into account the high prevalence of inflammatory periodontal diseases, the condition of periodontal tissues, and the gingival biotypes.
