Abstract

Aim: The present study aimed to find whether excessive occlusal force has any influence on the severity of periodontal disease and whether the occlusal correction done based on T-Scan evaluation has any influence on healing after periodontal therapy. Materials and methods: A total of 30 generalized chronic periodontitis patients contributing 692 teeth were selected for this randomized controlled clinical trial. Occlusal force analysis using T-Scan revealed 538 teeth with high occlusal force among 30 patients and were randomly assigned as either flap surgery (group I—14 patients contributing 262 teeth) or flap surgery with coronoplasty (group II—16 patients contributing 276 teeth). The clinical parameters including probing pocket depth (PPD), clinical attachment level (CAL), teeth mobility, and occlusal force percentage were recorded at baseline and 3 months. Paired t-test and independent t-test were done to compare PPD, CAL, and occlusal force within and between the groups, respectively. Mann–Whitney U test and Wilcoxon signed-rank test were done to compare mobility between and within the groups, respectively. Pearson correlation was used to correlate occlusal force and CAL. Results: Occlusal force was high among the teeth with severe CAL (7.621 ± 1.822) compared to moderate (5.897 ± 1.113) and mild (5.715 ± 1.134) CAL. There was a moderate positive correlation between occlusal force and severity of periodontitis (r = 0.608). The within-group comparison showed that there was significant reduction in occlusal force and all the clinical parameters assessed in both groups (p = 0.000). Intergroup comparison revealed that there was significant reduction in teeth mobility in group II compared to group II (p = 0.003). There was no statistically significant difference in terms of CAL (p = 0.356) and PPD (p = 0.369) between both groups. Conclusion: The study results revealed that there was a significant relationship between occlusal force and severity of periodontitis, and occlusal adjustment along with flap surgery resulted in significant reduction in teeth mobility but not in terms of clinical attachment loss and PPD. Clinical significance: Occlusal force analysis using T-Scan system provides a valuable aid in treating periodontal disease.
