Enlarged follicles associated with multiple unerupted teeth always comprise an area of considerable interest for oral and maxillofacial surgeons. The condition of multiple calcifying hyperplastic dental follicles is extremely rare and is characterized by multiple unerupted teeth with abundant calcifications and odontogenic epithelial rests in the enlarged dental follicles. We report an interest...

odontoma.2,3 Compound odontomas consist of tooth-like structures that radiographically appear as opacities. Complex odontomas comprise a mixture of odontogenic tissues without dental organization.2,4 Clinically, three types of odontomas are recognized in the literature: central (intraosseous) odontoma, peripheral (extraosseous or soft tissue) odontoma, and erupted odontoma.2,5 Odontomas are oft...

The aim of this study were to describe a clinical case of an intracoronal radiolucent lesion detected in unerupted mandibular first molar and to discuss the aetiology of the present case utilising immunocytochemical staining of the removed tissue from the lesion. In contact with the enamel surface and near the dentine fragment of the removed tissue, numerous multinucleated giant cells were obse...

If there are more than 32 teeth in the oral cavity, they are called supernumerous teeth. Distomolars are the fourth molar teeth, in the distal position to the wisdom teeth. Though, paramolars are the supernumerous teeth situated beside the molars. Correct diagnosis of supernumerous teeth is not always easy to conduct basing on pantomographic x-ray pictures. Obtained results indicate that unerup...

OBJECTIVE To determine the prevalence of preeruptive intracoronal dentin defects in Chinese children from panoramic radiographs, and describe the imaging characteristics of these lesions. METHODS A total of 707 panoramic radiographs with 8,171 unerupted permanent teeth were examined. Each unerupted tooth was examined with regard to the absence or presence of radiolucencies within the dentin o...

Retention, that is, a permanent tooth which is unerupted more than a year after the normal age of eruption, is a relatively rare event, except in the case of the third molars and the upper canines. Transmigration is defined as the phenomenon of more than half an unerupted impacted tooth crossing the midline. We report the clinical case of a twenty-year-old patient presenting transmigration of t...

Crown resorption of unerupted teeth in children has been reported in the dental literature (1). Such resorption may be similar to tooth resorption in adult teeth that have been embedded for long periods of time (2), but should be differentiated from external tooth resorption following trauma, infection, or excessive mechanical forces (3) and from internal tooth resorption originating from the d...

Adenomatoid odontogenic tumor (AOT) is a rare odontogenic tumor often misdiagnosed as odontogenic cyst. AOT is predominantly found in female patients, which usually arise in the second or third decade and is located more often in the maxilla than mandible and often associated with an unerupted permanent tooth. However, AOT frequently resembles other odontogenic lesions such as dentigerous cysts...

Dentigerous cysts can develop from unerupted primary, permanent, or rarely supernumerary teeth. When a supernumerary tooth is in the maxilla, near the midline, it is called a mesiodente. Such a mesiodente lies in the palate and a cyst developing about this tooth can extend directly up into the nasal fossae. More commonly a dentigerous cyst arising from unerupted maxillary teeth occurs about the...
