Evaluation of inorganic bovine bone graft in periodontal defects after third molar surgery

摘要

Aim: This study evaluated the e cacy of inorganic bovine bone graft (IBB) in periodontal defect after mandibular third molar (3M) surgery. Methods: The authors conducted a split-mouth, prospective, randomized, blinded, placebo-controlled clinical trial involving 20 participants with a mean age of 21.60 ± 6.5 years who had symmetrical bilateral lower 3M randomly assigned to receive IBB or left empty (blooding clot). The clinical variables studied were probing depth and clinical attachment level (CAL) at preoperative and postoperative periods of 10, 30, and 60 days. Radiographic measures included the distance from the alveolar bone crest to the cementoenamel junction and the bone density at 30 and 60 days postsurgical procedure. For statistical analysis, we used the paired t-test at a level of signi cance of 5%.Results: It was observed a reduction in pocket depth and CAL in both groups, but IBB did not provide better results than blooding clot (P > 0.05).On the other hand, IBB group showed an increased in the bone density, and a decrease in the periodontal defect on the distal surface of second molar (2M) after 30 and 60 days of surgery compared to the control group (P Conclusion: The use of inorganic bone graft (GenOx) did not enhance the probing depth after 3M removal. Although the radiographic ndings have showed an increase in bone density and a decrease in the periodontal defect on the distal surface of the 2M, we cannot recommend the use of IBB as a treatment for periodontal defect prevention after 3M removal.
