Oral and maxillofacial surgery is that part of dentistry which deals with correction of Jaw bone deformities, like proclination (over growth) of Jaw bone, over development of the jaw bone, accident causing fractures of facial bones, removed of large cyst, which does not respond to root treatment, if dental caries is the causative factor. And finally management of partially impacted wisdom tooth, which when partly erupted can cause secondary caries, especially in the area of the contact of the practically impacted tooth, due to food impaction occurring in that area.
