Introduction Genetic factors contribute to the aetiology of the ectopic canine (EC) (OMIM 189490), the inheritance pattern being autosomal dominant with variable expression and incomplete penetrance. However there is also evidence for an epigenetic component [1]. The Runx2 gene is intimately involved in the mechanism of tooth eruption. It controls differentiation and maturation of osteoblasts a...

BACKGROUND Ectopic eruption of a tooth or osteoma rarely occurs within the maxillary sinus. Coexistence of these two rare entities in the maxillary sinus has never been reported in the English literature. CASE REPORT Herein, we present a 21 year-old male patient with osteoma and ectopic tooth in the left maxillary sinus treated with the removal of the ectopic tooth by endoscopic sinus surgery...

The ectopic eruption of teeth into the nasal cavity is a rare phenomenon. Ectopic tooth eruptions commonly occur in the palate and maxillary sinus, but have also been reported in the mandibular condyle, coronoid process, orbit, and nasal cavities. The clinical manifestations of intranasal teeth are quite variable; however, intranasal teeth can be an incidental finding during routine examination...

Ectopic tooth eruption in a non-dental area is a rare entity, whereas in oral cavity it is most common. The ectopic development of teeth in non-dental localizations have been reported in the nasal cavity, chin, maxillary sinus, mandibular bone, palate and orbital cavity. Ectopic tooth eruptions in maxillay sinus are usually asymptomatic and found incidentally during routine clinical or radiolog...

Dental ectopia is a rare clinical finding characterized by a change in the normal tooth eruption pathway. In more severe cases, nontreated ectopia may develop into either partial or total transposition. The early diagnosis is of crucial importance for establishing a treatment planning correctly. Therefore, the present paper is aimed at reporting an unusual case of a 11-year-old boy with ectopic...

An ectopic tooth is an eruption of a into abnormal location, such as the palate, sinonasal cavities, mandibular condyle, coronoid process, orbit, or skin. It can be found incidentally presented with variety symptoms, unilateral nasal obstruction, epistaxis, rhinorrhea, chronic congestion, headache, facial pain. Ectopic teeth are most commonly supernumerary, but may also deciduous permanent teet...

Supernumerary teeth are considered as one of the most significant dental anomalies during the primary and early mixed dentition stages. They are of great concern to the dentists and parents because of the eruption, occlusal, and esthetic problems they can cause. Supernumerary teeth occur more frequently in the permanent dentition but rarely in primary dentition and more often seen in males. A s...

Tooth development results from a complicated multistep interaction between the oral epithelium and the underlying mesenchymal tissue. Abnormal tissue interactions during tooth development may potentially result in ectopic tooth development and eruption. We report a case of unerupted second molar and impacted third molar and an attempt is made to review possible causes of noneruption of teeth an...
