The impact of fixed and removable dental prostheses on the periodontal health of abutment teeth: A Retro-Prospective Comparative Study.

Introduction: Periodontal disease is the most prevalent oral condition worldwide, resulting from a prolonged inflammatory reaction triggered by the buildup of dental plaque. Many studies have concluded that there is a strong association between periodontal health and tooth restorations, as the periodontium must be healthy for the restoration to last. Aim: to evaluate the impact of fixed and removable dental prostheses on the periodontal health of abutment teeth. Methodology: This was a Results: Most of the prostheses were fixed (72.32 %), and most of them were bridges (60.71 %) located in the anterior region of the mouth (58.56 %). The study findings showed a significant increase (mean = 0.46 mm) in clinical attachment loss after prosthesis placement (p < 0.01), while no significant difference was observed in pocket depth (p = 0.062). Furthermore, there was a significant increase in plaque at the follow-up visit compared to the baseline visit (p < 0.01) for only the fixed dental prostheses. There was no significant difference between fixed and removable prostheses regarding their impact on the periodontal health of abutments. Conclusion: The study found that abutment teeth had increased clinical attachment loss after receiving dental prostheses, highlighting the need for regular maintenance and patient education to maintain periodontal health.
