Ectopic Tooth in Mandibular Canal, Maxillary Sinus, and Mandibular Condyle

Abstract

Eruption of tooth into place other than tooth-bearing region is defined as ectopic eruption. Although ectopic eruption of tooth is rare, there have been cases in the maxillary sinus, mandibular condyle, nasal cavity, chin, palate, and orbital floor. Due to ectopic teeth’s rarity and lack of consensus for ıts treatment, incidence was entitled to be added to literature and discussed. It was reported that odontogenic tumors and cysts can develop around the ectopic tooth. Thus, ectopic teeth can be followed up regularly in case of no signs and symptoms. If the patient has unusual orofacial pain, undiagnosed nasal discharge, maxillary sinusitis, preauricular pain, preauricular fistula, trismus, and lip paresthesia, the patient should be evaluated in terms of ectopic tooth. Whether the patient has signs and symptoms related to ectopic tooth, early intervention for the removal of ectopic tooth along with accompanying lesion is the treatment of choice. Specialists choose intervention way based on their experience. When selecting the intervention, minimally invasive and less morbid way should be preferred. Intraoral approach rather than extraorally should be the first choice to prevent unesthetic scar and damage to facial nerve.

Three-Dimensional (3D) Printing in the Case of a Concurrent Polyp and an Ectopic Tooth

“…Due to the rarity of teeth being found within the sinus, they are often found during routine clinical or radiographic examinations [ 5 ]. Rarely, ectopic teeth can cause temporomandibular pathologies, orofacial pain, facial swelling, pain, nasal obstruction, and sinusitis [ 6 ]. In our instance, the patient had rhinosinusitis that was worsened by an anthrochoanal polyp.…”

“…A symptomatic impacted ectopic tooth must be removed in order to avoid further issues and the recurrence of an underlying condition. However, the Caldwell-Luc procedure is the most common method utilised by surgeons to remove ectopic teeth from the maxillary sinus [ 6 ]. Other methods, such as nasal and transoral endoscopy, are available for removing ectopic teeth from the maxillary sinus.…”

All We Need to Know about Normal and Abnormal Human Teeth

“…One such problem is ectopic eruption. Akbas et al (2022) defined ectopic eruption as a condition in which the permanent teeth, because of deficiency of growth in the jaw or a segment of jaw, assume a path of eruption that intercepts a primary tooth, causes its premature loss, and produces a consequent malposition of the permanent tooth. Failure to treat ectopic eruption can result in loss of arch length, inadequate space for the permanent premolar, and malocclusion [56].…”

Failure to treat ectopic eruption can result in loss of arch length, inadequate space for the permanent premolar, and malocclusion [56]. An example of this anomaly is ectopic eruption of first permanent molars that can be positioned too far mesial into the alveolar bone and become impacted below the second permanent molar.…”

Orthodontic Management of Ectopically Erupted Maxillary Central Incisor: A Case Report

“…An ectopic tooth erupts in a position that is not its normal position in the dental arch. 1 The prevalence of ectopic eruption is 5.6% while maxillary incisors can be ectopically erupted or be impacted in 2% of the population. 2 Since maxillary anterior teeth are displayed during maximum period during speech and smile, it is often referred to as "social six".…”
