The objective of the study was to analyze 2-flap designs for surgical extraction of third molar, evaluating the periodontal status of the second lower molar.
Forty-five lower third molars were extracted from 24 patients. In 23 teeth, a vertical incision to the mandibular ramus was used (technique A), whereas 22 teeth were submitted to classic L-shaped flap (technique B) with controls at 60 and 90 days postoperatively.
Pearson correlation coefficient analysis showed a significant correlation only between immediate preoperative probing depth variables from techniques A and B in the studied surfaces. Statistical significances in the preoperative (vestibular) and postoperative day 60 (distovestibular and vestibular) were noted. In contrast, Student t-test showed no statistical difference in probing depths between preoperative and postoperative values, as well as no statistically significant difference regarding the type of incision alone.
Technique A allowed a less traumatic surgery, guaranteeing a more comfortable postoperative period.
本研究的目的是分析用于第三磨牙外科拔除的两种瓣设计，评估下颌第二磨牙的牙周状况。
从24例患者中拔除45颗下颌第三磨牙。23颗牙齿采用垂直切口至下颌升支（技术A），而22颗牙齿采用经典L形瓣（技术B），术后60天和90天进行对照。
Pearson相关系数分析显示，在所研究的表面上，技术A和技术B术前即刻探诊深度变量之间仅存在显著相关性。术前（前庭）和术后60天（远中前庭和前庭）有统计学意义。相比之下，Student t检验显示术前和术后探诊深度无统计学差异，单独切口类型也无统计学显著差异。
技术A手术创伤较小，保证了术后更舒适的时期。
