Abstract

Aim: The efficacy of guided bone regeneration technique in periradicular surgery by clinical and radiographic evaluation. Materials and Methods: A randomized clinical trial was conducted in which patients were assigned for periradicular surgery with guided bone regeneration technique [guided tissue regeneration membrane placed over hydroxyapatite bone graft in the bony defect, with 10 patients in group. Clinical and radiographic evaluation was performed at 1 month, 3 months and 6 months after the surgery. Results: Ten patients with an average age of 23.8 years having periapical lesions were assigned for periradicular surgery. Clinical and radiographic examination was performed 1 month, 3 months and 6 months after the surgery. There was   a significant difference found between the percentage reduction of the sizes  of the radiographic periapical lesions. Conclusion: The use of bone regenerative materials, such as bioabsorbable membranes and resorbable hydroxyapatite improved the predictability of clinical and radiographic healing.
