The treatment of choice for dentigerous cyst is enucleation along with extraction of the impacted teeth. [21] If eruption of the unerupted tooth is considered feasible, the tooth may be left in place after partial removal of the cyst wall. Orthodontic treatment may subsequently be required to assist eruption.
Treatment and prognosis are usually based upon keeping these teeth and preserving the alveolus. For erupted teeth, endodontics is an option if the tooth is devitalized and restorable. For unerupted teeth, function can be restored with a removable partial denture until all major growth has been completed and a final restoration can be placed. [2]
On radiographs, the adenomatoid odontogenic tumor presents as a radiolucency (dark area) around an unerupted tooth extending past the cementoenamel junction. It should be differentially diagnosed from a dentigerous cyst and the main difference is that the radiolucency in case of AOT extends apically beyond the cementoenamel junction.
In 1909, Charles A. Clark described a radiographic procedure for localizing impacted teeth to determining their relative antero-posterior position. [1] If the two teeth (or, by extension, any two objects, such as a tooth and a foreign object) are located in front of one another relative to the x-ray beam, they will appear superimposed on one another on a dental radiograph, but it will be ...
Where unerupted wisdom teeth still have eruption potential several predictors are used to determine the chance of the teeth becoming impacted. The ratio of space between the tooth crown length and the amount of space available, the angle of the teeth compared to the other teeth are the two most commonly used predictors, with the space ratio ...
Other impacted teeth, especially canines or incisors, can be aligned with the rest of the dental arch by orthodontic treatment, thus regaining and retaining their mechanical and aesthetic function. In some cases, impacted teeth can be let sleeping inside the alveolus, but periodical check-ups are required for a possible pathological development.
The first point of focus of oral, dental and maxillofacial radiology is to identify the problem from the patient's complaints. [ 5 ] [ 6 ] [ 7 ] All areas of the mouth and teeth are examined, not just existing complaints, and problems arising in these areas are referred for treatment without causing more serious problems in the future. [ 8 ]
Failure of eruption of teeth happens when a single or multiple teeth fail to erupt in the mouth. This can happen due to many reasons which may include obstruction from primary teeth, bone surrounding the unerupted tooth or other mechanical factors. The two types of failure of eruption are primary failure of eruption and mechanical failure of ...
