OBJECTIVE
To evaluate the effect of polylactic acid granules placed in third molar sockets on the incidence of alveolar osteitis.
STUDY DESIGN
A prospective randomized study with 161 patients (322 bilaterally impacted mandibular third molars).
RESULTS
The sockets in which the polylactic acid granules were placed had a significantly higher rate of alveolar osteitis (23.6%) than did the control sockets (13.58%). In all subgroups analyzed, the incidence of alveolar osteitis was higher in the experimental (polylactic acid) group.
CONCLUSION
On the basis of the findings of this study, polylactic acid granules do not reduce the incidence of alveolar osteitis and may actually contribute to a higher incidence of alveolar osteitis.
目的
评估将聚乳酸颗粒置于第三磨牙牙槽窝对干槽症发生率的影响。
研究设计
一项针对161例患者（322颗双侧阻生下颌第三磨牙）的前瞻性随机研究。
结果
放置聚乳酸颗粒的牙槽窝干槽症发生率（23.6%）显著高于对照牙槽窝（13.58%）。在所有分析的亚组中，实验组（聚乳酸组）的干槽症发生率更高。
结论
基于本研究结果，聚乳酸颗粒不能降低干槽症的发生率，实际上可能导致干槽症发生率升高。
