Extraction in orthodontics are carried out in the cases where there is space deficiency to align the teeth. The elective extraction of first or second premolars has been discussed in the literature for more than 50 years. In the 1940s and 1950s Nance, Dewel and Carey reviewed this as a useful option, and in the 1970s Logan and other leading orthodontists favoured the extraction as choice. It is not always the elective extraction of premolar is a smooth drive for the surgeon as well as to patient. Sometimes the elective extraction of premolar result in complications, which might be due to both anatomical and surgical factors.
The study sample consisted of 100 patients referred for one or more orthodontic extractions to the department of oral and maxillofacial surgery were included in this retrospective study at the vivekanandha dental college for women tiruchengode between November 2014 and May 2016. All referrals were from the department of orthodontics. A survey was carried out to record the intraoperative risks and correlated with its morbidity as when occured. All intraoperative morbities were managed appropriately as required.
Between November 2014 and May 2016, 100 patients had one or more premolar teeth removed by the oral surgeons. The sample size was 100 patients who had a total of 334 premolars removed. The sample's mean age was 11.4+- 8.4 years, and 57.0% were male. The average number of teeth extracted per patient was 2.34 +- 1.46, and 73.8% had complete root development. More than 93.4% of subjects had normal root and bone morphology, whereas 35.65% had variations in root forms and bone texture. The intra-operative and post operative complication rates were 7.4% and 1.9%, respectively. Complications were generally minor (91.9%) and were managed nonoperatively on an outpatient basis. There were no case of oral antral communication.
正畸治疗中的拔牙是在牙齿排列空间不足的情况下进行的。关于选择性拔除第一或第二前磨牙的讨论在文献中已有50多年的历史。在20世纪40年代和50年代，南斯、德韦尔和凯里将其视为一种有用的选择，而在20世纪70年代，洛根和其他主要正畸医生则倾向于将其作为首选。对于外科医生和患者来说，选择性拔除前磨牙并非总是一帆风顺。有时，选择性拔除前磨牙会导致并发症，这可能是由于解剖学和手术因素共同作用的结果。
本回顾性研究纳入了2014年11月至2016年5月期间在蒂鲁琴戈德维韦卡南达女子牙科学院口腔颌面外科转诊进行一次或多次正畸拔牙的100例患者。所有转诊均来自正畸科。进行了一项调查，记录术中风险及其发生时的发病率。所有术中并发症均根据需要进行了适当处理。
2014年11月至2016年5月期间，100例患者的一颗或多颗前磨牙由口腔外科医生拔除。样本量为100例患者，共拔除334颗前磨牙。样本的平均年龄为11.4±8.4岁，男性占57.0%。每位患者平均拔牙数为2.34±1.46颗，73.8%的患者牙根完全发育。超过93.4%的受试者牙根和骨形态正常，而35.65%的受试者牙根形态和骨质地存在变异。术中及术后并发症发生率分别为7.4%和1.9%。并发症一般较轻（91.9%）且在门诊进行了非手术处理。未发生口腔上颌窦交通病例。
