Abstract

Complicated tooth caries / deep periodontal infections spreading beyond the alveolar bone are usually main stay of odontogenic oro- facial infections. They extend to involve the fascial planes around the face and oral cavity causing facial swelling and contour abnormalities. They tend to spread along planes of least resistance involving the supporting structures of the affected tooth. The abscesses around the apices of the maxillary pre-molar and molar teeth usually results in Oro-antral fistula and periapical abscesses involving anteriorly located teeth notably the incisors can lead to Oro-nasal fistula formation
