Maxillary Dentigerous Cyst with Double Wolf Teeth in a 3-Year-Old Quarter Horse Mare

Dentigerous cysts are characterised by the formation of cysts containing dental material with a variable level of development. They are the result of a distinct embryological phenomenon. Usually, they are of significant clinical relevance in horses, especially in tandem with ectopic tooth. Contrarily, supernumerary teeth or typical polyodontias usually have limited impact. In this case report, we describe the occurrence of a supernumerary first premolar (Triadan 105). Dissimilar to known scientific literature however was the formation of a cystic structure around the supernumerary tooth. Surgical removal of the dentigerous cyst is discussed, as are the possible causes for the formation of the cystic structure. Based on this case report, we suspect that the formation of a cystic structure may not be limited to atypical polyodontias, as they may also occur in supernumerary teeth.

Hyperdentia in adult patient in the ENT practice

According to the literature, such dentition anomaly as supernumerary teeth is more common in the practice of a dentist than of an otorhinolaryngologist. Clinical manifestations of this pathology in adults are less frequent than in children. Periodically, there appear descriptions of individual cases of hyperdentia, in which the tooth is located in the nasal cavity, paranasal sinuses, orbit. It is not always possible to find such a tooth on examination, therefore, additional research methods help to determine the location and pathological process in more detail. We present our clinical observation of tooth retention and ectopia in the nasal cavity and upper jaw. The diagnosis was confirmed by the data of endoscopic examination and computed tomography of the paranasal sinuses. The ectopic tooth was found before the development of pronounced local inflammation. The tooth was removed from the nasal cavity using endoscopic techniques, no communication between the nasal cavity and the oral cavity was found. The postoperative period was uneventful. On examination two weeks after the operation, no pathological changes in the nasal cavity, paranasal sinuses were found, as well as defects in the mucous membrane and bone part of the nasal cavity floor.

Modified Endoscopic-Assisted Approach for Removal of Ectopic Third Molar in the Maxillary Sinus

This case series describes an alternative approach for removing ectopically erupted tooth in the maxillary sinus using an improved endoscopic approach known as modified endoscopic-assisted sinus surgery (MESS). We reviewed medical charts and radiographs of patients who underwent surgical removal of an ectopic tooth in the maxillary sinus using MESS. The surgical technique consisted of creating a bony window in the maxillary sinus wall with a pre-adapted microplate, which was repositioned after the tooth was removed. For all the patients included in this study, there were no postoperative complications clinically and radiographically. At the time of microplate removal, satisfactory bone regeneration was observed around the bony window margins of the maxillary sinus wall. MESS is an effective technique that modifies and integrates the techniques of the conventional Caldwell-Luc procedure (CLP) and functional endoscopic sinus surgery (FESS) and can be used to remove ectopic tooth in the maxillary sinus by avoiding the risk of postoperative sinus-related complications.

A Rare Case Report of Ectopic Tooth in Submandibular Salivary Gland’s Duct

This case report highlights mandibular tooth in an ectopic position in the floor of the mouth, associated with submandibular salivary gland, which was completely obliterating the Wharton duct. Very few such cases have been reported in the literatures. Since ectopic tooth may lead to pain, discomfort sensation upon mastication, and even infection (sialadenitis), its diagnosis and treatment is essential.
