effect of periodontal therapy on maxillary sinus mucous membrane thickening in chronic periodontitis: a split-mouth study

Background. this study evaluated the effect of periodontal therapy on mucous membrane thickening in maxillary sinus in chronic periodontitis patients using radiovisiography (rvg) and cone-beam computed tomography (cbct). methods. the study population included 30 patients diagnosed with chronic periodontitis, exhibiting bilateral mucosal thickening of maxillary sinus. the selected sites were randomly assigned to group i (control group - not receiving periodontal therapy) and group ii (test group - receiving periodontal therapy). the clinical parameters and mucosal thickening of the maxillary sinus were evaluated at baseline and after 9 months. results. there was a significant decrease in the ppd, cal as well as mucosal thickening in group ii while, group i showed an increase in these parameters. in group ii at the end of 9 months the mean mucosal thickening reduction as assessed by cbct was 0.76±0.18, 0.73±0.24, 0.88±0.42 and 1.13±0.43 mm at the most anterior point (ap), the most posterior point (pp), the mid-point (mp), point of maximum thickness (mt) as well as in the length of the thickened mucosal lining, respectively. conclusion. the results of our study indicated a reduction in the mucosal thickening of the maxillary sinus after surgical periodontal therapy. the trial was registered with the clinical trial registry of india (trial ref/ 2016/02/010805).
