Shape-unilocular, usually round or oval often surrounds an entire unerupted tooth Outline-smooth and well defined well corticated Radiodensity- initially radiolucent,but small opacities(snowflakes) within central radiolucency may be seen peripherally as the lesion matures Effects-adjacent teeth displaced, rarely resorbed Assoc. tooth often unerupted Buccal/palatal expansion

Radiolucent lesions within the jaws represent a whole variety of lesions. Generally, they can be classified into two categories. The first category comprises well circumscribed lesions, either

In the upper jaw it is common in the canine tooth area. This cyst has its highest incidence during the 2nd and 3rd decades of life. Radiologically the presence of pericoronal radiolucency is a diagnostic pointer. This tumor should be differentiated from ameloblastoma, odontogenic keratocyst and calcifying odontogenic cyst. All Ill-defined unilocular radiolucency was the most common (70.8%) radiologic feature.

Assymptomatic, <20 yrs old, jaw swelling in posterior mandible. Radiolucent lesion that can  The ameloblastic fibroma appears as an asymptomatic radiolucent lesion, often associated with an impacted tooth and indistinguishable from an odontogenic cyst. A cyst is a pathological epithelial lined cavity that fills with fluid or soft material and usually grows from internal pressure generated by fluid being drawn into the cavity from osmosis (hydrostatic pressure). The bones of the jaws, th Mar 21, 2019 Jaw cysts are sack-like pouches that fill with fluid and form within the tissues of the jaw. These growths are not just limited to the jaws, because  Radiolucencies involving jaws, anatomic or pathologic are very common, which can occur both in maxilla and mandible. Among these, pathologic  Keywords: Mandibular condyle, Radiolucencies, Preauricular swelling. mandible.

On the Calcifying odotogenic cyst is a benign odontogenic tumor of cystic type most likely to affect the anterior areas of the jaws. It is most common in people in their second to third decades but can be seen at almost any age. On radiographs, the calcifying odontogenic cyst appears as a unilocular radiolucency (dark area). Ameloblastoma is the second most common odontogenic neoplasm, accounting for 11% of all odontogenic tumors in the jaw .

Lucency may be conferred by a cystic process (e.g. periapical cyst) or a lytic process (e.g. mandibular metastases). This chapter is designed to simplify the process of arriving at a radiological differential diagnosis when confronted with a radiolucency of unknown cause on a plain radiograph.

• Although most radiolucent lesions with well-defined sclerotic borders are benign, MRI may reveal clinically unsuspected malignant disease.
