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...

BACKGROUND Ectopic eruption of teeth in non-dental sites is a rare phenomenon and can present in a variety of ways such as chronic or recurrent sinusitis, sepsis, nasolacrimal duct obstruction, headaches, ostiomeatal complex disease and facial numbness. However, presentation of such patients with recurrent haemoptysis has not been described in the literature so far. We have described a case of ...

This case report summarizes the sequence of events that led to the detection of a molar pregnancy missed by ultrasound and initial pathology examinations. This patient illustrates that following serial quantitative beta-human chorionic gonadotropin (B-hCG) levels after spontaneous, therapeutic, and elective abortions will help detect potentially life-threatening molar and ectopic pregnancies. F...

Ectopically erupted tooth is a rare disease, indicating that a tooth erupts into regions other than the oral cavity. We present a case of an ectopic maxillary third molar tooth in the external acoustic meatus, and discuss the diagnosis and treatment of this entity.

Dentigerous cysts are the most common developmental odontogenic cyst of the jaws. They are more frequent in males and although most often affected teeth are maxillary canines and mandibular third molars, they may also be related with supernumerary or an ectopically erupted tooth. Our aim was to report the management of ectopic third molar tooth related with a dentigerous cyst in maxillary sinus...

Tooth anatomic factors like ectopic enamel pearls are often associated with localized periodontal inflammation and bone loss. There are no existing paleopathological data for such structural anomalies in ancient populations associated with periodontal pathology in the literature. A rare case of enamel pearl on the maxillary right first molar of women associated with localized periodontitis is p...
