The ectopic eruption of a supernumerary tooth can occur in the sinonasal area, but due to its rarity, few cases of ectopic tooth eruption in the maxillary sinus have been reported. A fungus ball in the paranasal sinuses usually involves just one sinus, most frequently the maxillary sinus. Here, the authors present a case of an ectopic supernumerary tooth embedded in a fungus ball of the maxillary sinus.

3.Experts' consensus on ectopic eruption of the maxillary permanent first molar.
Chinese Journal of Stomatology 2022;57(3):213-219
Ectopic eruption of the maxillary permanent first molar refers to its deviation from the normal position due to some factors during the eruption process, which will lead to root resorption and early loss of the adjacent second primary molar, mesial movement itself, or serious malocclusion. To solve these problems, the Society of Pediatric Dentistry of Chinese Stomatological Association organized pediatric dental experts from 16 universities and hospitals, including West China Hospital of Stomatology, Sichuan University, Peking University School and Hospital of Stomatology, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine to carry out a panel discussions. The research, and diagnosis and treatment experiences of ectopic eruption of maxillary permanent first molar at home and abroad in recent years were also referred to. The present guideline was eventually developed for the reference of dental clinicians.

4.Cone beam computed tomography findings of ectopic mandibular third molar in the mandibular condyle: report of a case.
Imaging Science in Dentistry 2011;41(3):135-137
Impaction of third molar is a common developmental abnormality. However, ectopic impaction of the mandibular third molar in condylar region is an extremely rare condition. This report describes a case of impacted tooth in the mandibular condyle without any associated pathologic condition. Also, this report presents the spatial relationship of the impacted mandibular third molar to the surrounding anatomic structures using cone beam computed tomography.

5.Clinical effects of modified Nance arch appliance in the treatment of ectopic eruption of maxillary first permanent molar.
Chinese Journal of Stomatology 2014;49(1):32-36
OBJECTIVETo evaluate the effect of modified Nance arch appliance in the treatment of ectopic eruption of maxillary first permanent molar.
METHODSThirty children with unilateral ectopic eruption of maxillary first permanent molar were treated with modified Nance arch appliance. The mesial angle of the maxillary first permanent molars and the magnitude of the primary second molar distal root lesion before and after treatment were measured on the panoramic radiographs and analyzed statistically.
RESULTSAll 30 children completed the treatment. The mesial angle of the ectopic side significantly changed from (75.2 ± 7.6) ° before the treatment to (92.9 ± 5.2) ° after the treatment (t = -11.082, P < 0.05). The root lesion of the ectopic side significantly enlarged after the treatment, but there was no significant change on the normal side.
CONCLUSIONSThe treatment of ectopic eruption of the maxillary first permanent molar using modified Nance arch appliance was successful. The attention should be paid to the magnitude of the primary second molar distal root lesion before and after treatment and it is suggested to start the treatment when mild root resorption appears.

Supernumerary, ectopic tooth eruption in a non-dental area is a rare entity. The ectopic development of tooth found in non-dental environment has been reported in places such as the nasal cavity, chin, maxillary sinus, mandibular bone, palate and orbital cavity. Ectopic tooth eruptions in the maxillary sinus are usually asymptomatic and are found incidentally during routine clinical or radiological investigations. The diagnosis is usually made by plain-film radiography. Computed tomography is indicated when an ectopic tooth is found prior to surgery. Standard treatment for an ectopic tooth is extraction of the tooth. Here, the authors present a case of supernumerary, ectopic tooth found in the maxillary sinus associated with a mucocele.

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 in patients without nasal discomfort. Herein we report a unique case of an intranasal ectopic tooth that erupted into the nasal cavity and caused significant nasal symptoms in an otherwise healthy patient. The intranasal tooth was removed endoscopically.
