Dento-alveolar surgical procedures involving third molar teeth are the most common surgical procedure in the field of surgery. The objective of this research was to analyse the impact of surgery on the incidence of alveolar osteitis after surgical removal of mandibular third molar and to compare two different bone cutting methods following impacted mandibular third molar surgery..
This double blinded randomized clinical trial was executed at the OPD of Department of Oral and Maxillofacial Surgery, Dow University of Health Sciences, Karachi. The study duration was four months. It was conducted on 60 patients needing unilateral mandibular third molar impaction removal. Patients were randomized to two groups (i.e., physio dispenser group and slow speed handpiece group) before surgery. The surgical procedure was performed under local anaesthesia by using standardized cross infection protocol. The frequency of alveolar osteitis was evaluated on thirdday postoperatively. Alveolar osteitis was diagnosed and confirmed by patient's history and clinical evaluation. Post-operative sequelae were observed and recorded objectively.
Out of 60 patients', five patients experienced alveolar osteitis, and the incidence rate was 8.3%. A significant pvalue of 0.000 was calculated using binomial test for comparison of alveolar osteitis among both groups. Inter-examiner reliability was assessed by kappa and good (62%) agreement, which was found among the examiners, who diagnosed alveolar osteitis clinically. Post-operative sequelae were insignificant in slow speed hand piece group.
It was observed that alveolar osteitis was reported in physio-dispenser group; similarly, post-operative complications were also more in this group as compared with slow speed-hand piece group. No surgical complications were observed in slow speed-hand piece group suggesting slow speed hand piece mode of osteotomy to be safer for third molar extraction as compared with physio-dispenser.
涉及第三磨牙的牙槽外科手术是外科领域最常见的外科手术。本研究的目的是分析手术对下颌第三磨牙拔除术后牙槽骨炎发生率的影响，并比较下颌阻生第三磨牙手术后两种不同的截骨方法。
这项双盲随机临床试验在卡拉奇道健康科学大学口腔颌面外科门诊进行。研究持续时间为四个月。对60例需要单侧下颌阻生第三磨牙拔除的患者进行了研究。手术前，患者被随机分为两组（即物理 dispenser 组和慢速手机组）。手术在局部麻醉下按照标准化的交叉感染方案进行。术后第三天评估牙槽骨炎的发生率。通过患者病史和临床评估诊断并确认牙槽骨炎。客观观察并记录术后后遗症。
在60例患者中，有5例发生牙槽骨炎，发生率为8.3%。使用二项式检验计算两组牙槽骨炎比较的显著p值为0.000。通过kappa评估检查者间的可靠性，临床诊断牙槽骨炎的检查者之间有良好（62%）的一致性。慢速手机组术后后遗症不明显。
观察到物理 dispenser 组报告了牙槽骨炎；同样，与慢速手机组相比，该组术后并发症也更多。慢速手机组未观察到手术并发症，这表明与物理 dispenser 相比，慢速手机截骨方式在第三磨牙拔除中更安全。
