The crevicular incision is a very simple incision. It has many applications in various surgeries like flap surgery, apicoectomy, transalveolar extraction, bone biopsy and orthognathic surgery. In the management of fracture mandible, a routine vestibular incision is used. There are many complications associated with the vestibular incision like infection, wound dehiscence, mental nerve injury. These postoperative complications are rare with the crevicular incision. Like in other oral surgeries it can also be used as one of the approach to access fracture in the mandible. It not only provides wide surgical exposure but simultaneously it gives more visibility to both upper and lower limits of the fracture line. Since this incision crosses the sulcus of gingiva it can affect the health of gingival tissues. With this question, we planned this study to find out the outcome of the crevicular incision on periodontal health if used in open reduction & internal fixation. This study was done on patients with isolated mandibular fractures of symphysis and body region. Comparison of crevicular incision (study group) with a vestibular incision (control group) was done on the basis of certain periodontal indices (Gingival index, Pocket probing depth, Clinical Attachment level) which was recorded preoperatively and postoperatively after 6 weeks, and 12weeks. The results of the current study revealed that well performed ORIF for fracture mandible by using crevicular incision does not lead to periodontal problems. It showed almost similar long-term outcomes compared to the vestibular incision in ORIF.
