 Postoperative pain was assessed using a 10-point visual analog scale VAS with a score of 0 equals no pain and 10 equals very severe pain Facial swelling was assessed by modification of Schultze-Mosgau et al method, and this involved measuring the length from the tragus to the oral commissure and tragus to the pogonion. The arithmetic sum of the two measurements was considered as facial swelling at the time point. The maximum distance between the maxillary central incisors and the mandibular central incisors was taken as mouth opening. The difference between postoperative and preoperative mouth opening value was considered as trismus. Assessment of soft tissue healing was based on the criteria given by Landry et al. and Gonshor et al. Third molar sockets were assessed radiographically for bone healing by modification of Kelleys method as described by Olufemi et al. The percentage of facial swelling and mouth opening was estimated using the method described by Ogundipe et al.
