  1. *: Significant, p < 0.05
  2. 1 Mouth opening was measured by taking the maximum distance between the maxillary and mandibular central incisors using a caliper. Mouth opening was consider as the percentage difference between the two measurements
  3. 2 Swelling was measured by a tape measuring method and two measurements were taken between the tragus to lip junction and the distance between the external corner of the eye to the mandibular angle. Swelling was considered as the difference between the two measurements
