Abstract

Introduction: Pulpal and periodontal diseases are main etiological factors of tooth mortality. Inter relationship between these two diseases is the topic of research. Less literature is available on the effect of endodontic treatment of periodontal tissue healing. The, present study is conducted to evaluate effect of regenerative periodontal therapy in vital and non-vital teeth.

Materials and Methods: 10 sites with intrabony defect requiring regenerative periodontal therapy divided into 2 groups, Group-I 5 sites with intrabony defect where tooth is nonvital and root canal treatment is completed. Group-II 5 sites with intrabony defect and tooth is vital. At baseline sites were measured for probing pocket depth (PPD), clinical attachment level (CAL) and radiographic bone defect depth. 6 month post operatively sites were measured for probing pocket depth (PPD), clinical attachment level (CAL) and radiographic bone fill. After phase I therapy, follow up was done at 6 weeks. Intrabony defect ≥ 5mm clinically and ≥ 3mm radiographically were included in the study. Regenerative periodontal therapy with DFDBA and chorion membrane was performed.

Result and Conclusion: In Group I the mean reduction in pocket depth from baseline to 6 months   was 3.3±0.42, gain in clinical attachment level was 3.6 ± 0.4 and amount of bone fill was 3.6±0.54 which was statistically significant. In Group II the mean reduction in pocket depth from baseline to 6 months was 3.78±0.78, gain in clinical attachment level was 1.9 ±0.3 and the mean amount of bone fill was 2.8±0.57 which was statistically significant. On intergroup comparison the mean reduction in PPD and  gain in CAL  were  not statistically significant and the radiographic bone fill was statistically significant.
