Abstract

Inflammatory lesions, like periapical/odontogenic abscesses, are by far the most common pathologic condition of the jaws. Radiographically, these lesions commonly manifest as widening of periodontal ligament space, discontinuity of lamina dura and ill-defined periapical radiolucency. There are some rare disorders which could cause similar radiographic changes in the jaw bone. With careful scrutiny of periapical radiolucency, regular periodic follow-up radiographs and histo-pathologic examination, the periapical abscess or infection can be differentiated from rare fatal disorders.

Clinical Relevance: This paper highlights the need for vigilant examination of even the commonest, innocuous-appearing periapical changes which sometimes are produced by some rare fatal disorders.

Radiolucent shadows are cast over the periapical regions of teeth in practically all oral radiographic surveys of dentulous patients. Some of these periapical radiolucencies represent innocent anatomic variations, whereas others are caused by benign conditions and require treatment to preserve the associated teeth; still others represent systemic disease conditions that often become the responsibility and obligation of the dental clinician to recognize and bring to the attention of the patient's physician.1

The high incidence and broad spectrum of conditions causing periapical radiolucencies make it imperative that all dental clinicians should acquire a broad and comprehensive working knowledge of the conditions responsible for creating periapical radiolucent shadows.

This paper presents a case of osteosarcoma of the mandible that was first diagnosed and treated as a dental periapical lesion and discusses similar rare cases.

A 29-year-old Indian female patient reported to the Oral Medicine, Diagnosis and Radiology Department of Government Dental College Mumbai, with the complaint of a non-healing extraction wound in the right mandibular posterior region one month post-extraction with numbness over the right side of her lower lip for two months.
