title: Modified lingual split technique versus conventional buccal technique in odontectomy of impacted mandibular third molars.
abstract: This study was conducted to compare two different techniques used in odontectomy of impacted mandibular third molar; the modified lingual split technique and the conventional buccal technique as regarding the duration of surgery as well as the incidence of postoperative sequelae such as pain, edema, and trismus. This study was carried out on thirty adult male patients having class II, position B mesioangular impacted mandibular third molar scheduled for removal, the cases were divided into two equal groups. Group one using the conventional buccal technique and group two using the modified lingual split technique. Pain was categorized into a three grade scale according to the dose of the analgesic taken by the patients postoperatively. The degree of trismus was calculated by measuring the interincisal distance when the mouth was opened at a maximum using a graduated caliper both preoperatively and postoperatively. Edema was measured linearly using a tape between different predetermined facial anatomical landmarks in different planes. All measurements were carried out immediately before surgery and after one, two and seven days postoperatively. The collected data were tabulated and were statistically analyzed. There was a significant difference between the two techniques as regarding the duration of surgery in favour of the modified lingual split technique, with a mean of 36.3 minutes, in group two against a mean of 54.3 minutes in group I. As regarding pain there was no significant difference in the first and the second postoperative days, while there was a significant difference in favour of the modified lingual split bone technique in the seventh postoperative day. Trismus and edema were comparable in both groups.
