Assessment of the efficacy of periodontal tissue regeneration using non-resorbable and bioabsorbable GTR membrane-A clinical comparative study

Aim: The present study aims to assess the efficacy of non-resorbable and bioabsorbable guided tissue regeneration (GTR) membrane periodontal tissue regenerative methods. Materials and methods: Thirty teeth taken from 20 patients (8 males and 12 females) within the age range of 20-55 years having chronic periodontitis were enrolled in this trial. All the enrolled patients underwent phase I therapy which included scaling and root planing performed in two sittings by a single practitioner. Patients who fulfilled the selection criteria entered the study and were randomly allocated to the three groups. Group I: control group, group II: patients who received a non-resorbable GTR membrane, and group III: patients who received a bioabsorbable GTR membrane. The clinical parameters that were documented at baseline, 3 months, and 6 months postoperatively were the gingival index, plaque index, and probing depth (vertical and horizontal) for all the three groups. Results: The mean gingival index score was 1.64 ± 0.32 in group III at baseline, which decreased to 1.20 ± 0.10 at 6 months postoperatively. The plaque index reduced from 1.36 ± 0.46 at baseline to 1.04 ± 0.01 at 6 months postoperatively. The vertical and horizontal probing depths demonstrated a statistically significant difference between all the three groups. Conclusion: The present study established that both membranes resulted in clinically and statistically significant improvements in the treatment of grade II furcation defects.
