To evaluate lingual split technique vs buccal guttering in the extraction of lingually placed impacted mandibular third molar and to assess the clinical outcome of the two techniques in relation to pain, swelling, mouth opening, intra-operative time, dry socket, paraesthesia due to injury to the lingual and inferior alveolar nerve and hemorrhage.
The present clinical study comprised of 36 lingually impacted mandibular third molars. Patients were divided into two groups, and bone covering the third molar was removed by the lingual split technique using chisel and mallet and buccal guttering approach technique using rotary instruments.
The conventional buccal guttering technique took longer time with higher incidence of dry socket than the lingual split technique. Significant findings were also recorded in the lingual split technique in terms of pain, swelling, and trismus. Postoperative nerve injury was significantly higher in lingual split technique.
The study concluded that lingual split technique using chisel and mallet is found to be better than the buccal guttering approach technique using rotary instruments.
评估舌侧劈开技术与颊侧沟法在下颌第三磨牙舌侧阻生拔除术中的应用,并评估这两种技术在疼痛、肿胀、张口度、手术时间、干槽症、舌神经及下牙槽神经损伤导致的感觉异常和出血方面的临床结果。
本临床研究纳入36颗下颌第三磨牙舌侧阻生病例。患者分为两组,分别采用凿子和锤子进行舌侧劈开技术去除覆盖第三磨牙的骨质,以及使用旋转器械的颊侧沟法技术。
传统颊侧沟法技术耗时更长,干槽症发生率高于舌侧劈开技术。舌侧劈开技术在疼痛、肿胀和牙关紧闭方面也有显著结果。舌侧劈开技术术后神经损伤明显更高。
研究得出结论,使用凿子和锤子的舌侧劈开技术优于使用旋转器械的颊侧沟法技术。
