The border of the cyst is seen as a narrow opaque margin contiguous with the lamina dura. In cysts that are actively enlarging, peripheral areas of the margin may not be present. Periapical cysts have a characteristic unilocular [8] shape on radiographs. There is also a severe border of cortication [9] between the cyst and surrounding bone ...
On the other hand, only 2.7 percent of dentigerous cysts involved the maxillary premolar. Mourshed stated that the incidence of dentigerous cyst has been reported as 1.44 in every 100 unerupted teeth, [12] so dentigerous cysts involving the premolars are rare. Dentigerous cysts most commonly occur in the 2nd and 3rd decades of life.
The order of the jaw cysts from most common to least common is; radicular cysts, dentigerous cysts, residual cysts and odontogenic keratocysts. Radicular lesions are most commonly found in the anterior region of the maxilla 12 – usually around the canines. 11 The majority of cysts are of inflammatory origin 12.
It is considered that these cell rests proliferate to form epithelial lining of various odontogenic cysts such as radicular cyst under the influence of various stimuli. They are named after Louis-Charles Malassez (1842–1909) who described them.

Odontogenic keratocysts are usually noted as incidental radiographic findings. Radiographically they can be seen as unilocular or multilocular radiolucencies. They can be mistaken for other cysts such as residual cysts or a dentigerous cyst if they occur over an unerupted tooth. [8] Relative incidence of odontogenic cysts. [9]
The types of methods used to treat this type of cyst are curettage and bone grafting, aspiration, steroid injections, and bone marrow injections. Watchful waiting and activity modifications are the most common nonsurgical treatments that will help resolve and help prevent unicameral bone cysts from occurring and reoccurring.
