This study evaluated the effect of alloplastic bone grafts in osseous defects following surgical removal of horizontally impacted third molars by comparing the periodontal measures distal to the second molar in grafted and nongrafted third molar extraction sites. Materials and Methods: A double-blind, randomized, controlled clinical trial was designed on subjects with bilateral horizontally impacted mandibular third molars. Grafting consisting of alloplasts at the third molar extraction sites was compared with nongrafted sites. This study assessed 54 randomized sites in 27 patients who were selected using a split-mouth design. The predictor variable included the change in pocket depth distal to the mandibular second molar and associated dentin hypersensitivity around the second molar, assessed preoperatively and at 3 and 6 months after third molar surgery. The data regarding pocket depth reduction was statistically analyzed using paired t-test. The data concerning reduction in dentin hypersensitivity was statistically analyzed using chi-square test. Results: Six months after third molar surgery, mean pocket depth distal to mandibular second molar decreased significantly at the grafted sites compared to the nongrafted sites. The reduction in dentin hypersensitivity of mandibular second molar was statistically significant for the grafted sites at 6 months, compared to the nongrafted sites.
本研究通过比较第二磨牙远中受植区和未受植区的牙周指标，评估了外科拔除水平埋伏第三磨牙后使用同种异体骨移植对骨缺损的影响。
对双侧下颌水平埋伏第三磨牙的患者进行了一项双盲、随机、对照临床试验。将同种异体骨移植于第三磨牙拔牙窝与未受植区进行比较。本研究共评估了 27 名患者的 54 个随机部位，采用分牙设计。预测变量包括下颌第二磨牙远中牙周袋深度的变化和第二磨牙周围的牙本质过敏症，在第三磨牙手术后 3 个月和 6 个月进行评估。使用配对 t 检验对牙周袋深度减少的数据进行统计学分析。使用卡方检验对牙本质过敏症减少的数据进行统计学分析。
第三磨牙手术后 6 个月，受植区下颌第二磨牙远中牙周袋深度较未受植区显著降低。与未受植区相比，受植区下颌第二磨牙牙本质过敏症的减少在 6 个月时有统计学意义。
