Abstract

Abstract:

Objective To investigate the factors influencing changes in residual ridge height (RRH) and maxillary sinus mucosal thickness (MT) in the maxillary molar region of patients with periodontitis. Methods A retrospective analysis was conducted on clinical and cone beam computed tomography(CBCT) data from 200 patients with periodontitis (742 maxillary molars). Factors analyzed included molar loss status, severity of alveolar bone loss, maxillary sinus mucosa (MSM) thickening, treatments received during the observation period, baseline RRH and MT, as well as patients’ gender and age, to evaluate their effects on changes in RRH and corresponding MT. Results The mean change in RRH among the 742 maxillary molars was (-0.30±1.27) mm, with a rate of (-0.05±0.24) mm/month. The mean change in MT was (-0.42±3.55) mm, with a rate of (-0.06±0.61) mm/month. Alveolar bone loss less than the middle third of the root (P=0.010) and initial periodontal therapy during the observation period (P=0.006) were positively correlated with RRH change, whereas baseline RRH (P<0.001) and thickened MSM (P=0.007) were negatively correlated. Alveolar bone loss less than the middle third of the root (P=0.009) and initial periodontal therapy during the observation period (P=0.042) were positively correlated with the rate of RRH change, while baseline RRH (P<0.001) and tooth extraction during the observation period (P=0.010) were negatively correlated. Baseline MT (P<0.05) and tooth extraction after initial therapy during the observation period (P<0.05) were negatively correlated with both the magnitude and rate of MT change. Conclusion During the observation period, both RRH and MT in the maxillary molar region of patients with periodontitis showed an overall decreasing trend. Initial periodontal therapy may reduce alveolar bone loss and promote recovery of inflamed, thickened MSM, whereas tooth extraction has been clearly shown to accelerate alveolar bone loss.
