Abstract
AIM: To investigate the role of periodontal defect types on pocket healing MATHERIALS AND METHODS: Forty patients treated in a specialist and controlled environment were retrospectively selected. Pockets with probing depth (PD) > 4 mm were included and divided into infra- and supra- bony defect types according to clinical attachment level differences. The impact of defect type and other covariates on the probability of pocket closure (PD ≤ 4 mm) 3 (T1) and 6 months (T2) after non-surgical periodontal therapy was explored using a logistic multilevel model. RESULTS: The logistic model at T1 revealed a significant impact of smoking (p<0.001), heavy smokers (OR=0.22; p<0.001), FMPS (OR=0.98; p=0.017) multi-rooted teeth (OR=0.42; p<0.001), PD (OR=0.44; <0.001) negatively affected closure rate, while suprabony (OR=1.89 p=0.006) was a positive condition. The same analysis revealed female patients (OR=2.48; p=0.021), suprabony defects at T1 (OR=2.22; p=0.003), low levels of PD at T1 (OR=0.34; p=0.001) to increase closure rate at T2. Opposite to that, multi-rooted teeth affected negatively the success at T2 (OR=0.50; p<0.036). CONCLUSION: Infrabony defects significantly reduced closure rate 3 and 6 months after NSPT, together with female gender, heavy smoking, high FMPS at baseline, multi-rooted teeth, high initial PD and presence of plaque at the site.
