Evaluation of Periodontal Status of Adjacent Teeth to Posterior Single-Tooth Implant during a One-Year Period after Restoration: A Cross-Sectional Study

Abstract

Objective: To evaluate the periodontal status of teeth adjacent to the posterior single tooth implant during one year after restoration. Material and Methods: In this cross-sectional study, 36 patients, which were systematically and had received the implant(s) of single posterior teeth over the past year were selected. The teeth adjacent to single-posterior tooth implants were evaluated regarding bleeding on probing, mobility, gingivitis and periodontal pockets during the follow up period of 3, 6 and 9 months under the supervision of two specialists. To investigate the relationship between periodontal statuses, the Chi-square test was used, and the Kruskal-Wallis test was used to assess statistical significance of periodontal indexes in the period under assessment. The p-value of less than 0.05 was considered significant. Results: There was no significant relationship between the variable of bleeding on probing, mobility, gingivitis and periodontal pocket in the studied distal and mesial teeth. Out of studied patients, after 9 months, only 11.1% had one of the periodontal problems, as a result, 88.9% of crowns replacement of single-posterior tooth does not make any periodontal damages to adjacent teeth. Conclusion: Crowns replacement of implant does not have any destructive impact on periodontal condition of adjacent teeth.
