UNASSIGNED: Ectopic teeth arise from developmental abnormalities, pathological conditions or iatrogenic factors. They can be supernumerary, deciduous or permanent and cause dental and facial pain, swelling and infection. Limited cases reveal limited knowledge about causes, symptoms, treatment options and surgical procedures. A thorough evaluation, including radiographic imaging and clinical examination, aids diagnosis and treatment planning.
UNASSIGNED: A 54-year-old female patient complains of tooth mobility in the upper right back tooth region for one month and occasional pain in the right pre-auricular region.
UNASSIGNED: Chronic generalised periodontitis with an impacted tooth in the right condylar region.
UNASSIGNED: Extraction of Grade III mobile 17 and conservative treatment for ectopic molar in the condylar region.
UNASSIGNED: The patient is on regular follow-up with no similar complaints.
UNASSIGNED: A personalised approach is crucial in managing ectopic mandibular third molars and should take into account the patient\'s symptoms, preferences and potential complications. Successful treatment requires informed decision-making and thorough evaluation.

Ectopic tooth in maxillary sinus is a rare entity. There are many causes of this condition include developmental disturbance, pathological process, iatrogenic, and in some cases there is no identified cause. The ectopic tooth could be asymptomatic or presented with various symptoms depends on its location. A 19-years-old woman presented with left-sided facial pain and slight swelling at the site of the upper 3rd molar tooth for three months. She gave a history of mid-facial trauma with an operation in this area, 11 years ago. Orthopantography and computerized tomography confirm the diagnosis of ectopic tooth within the maxillary sinus. The tooth was removed by Caldwell-Luc procedure. The patient was remained free of the presenting symptoms at three months follow-up. Reporting any case of an ectopic tooth deserves the ability to know the various aspects of this condition. We reported a further case of ectopic 3rd molar tooth in the left maxillary sinus, most probably, due to previous mid-facial trauma or the surgery in this area.

Ectopic occurrence of mandibular third molar is a rare incidence. Usually found along with a cystic lesion or diagnosed incidentally during routine check-up. Owing to the rarity, only few cases were reported in the literature. The common site is the mandibular condyle followed by sigmoid notch, and often found in females. The frequent symptoms are obscure facial pain, trismus or the symptoms of the associated pathology like dentigerous cyst. The etiopathogenesis is uncertain and optimal management is still unclear. The symptomatic tooth should be removed either intraorally or extraorally. Here we report a case of ectopic mandibular third molar in ramus region surgically removed intra orally by high lingual split access osteotomy.

BACKGROUND: Intranasal teeth are a rare form of ectopic teeth. Their clinical manifestation are truly variable. In children, intranasal teeth are typically associated with cleft lip and alveolus.
METHODS: Here, we report a case of 11 years -old girl presented with right nasal obstruction and occasional headache without any obvious etiology. 0Computed tomography of the paranasal sinuses (coronal and axial view) revealed displaced right upper maxillary tooth with the crown oriented inferiorly and medially toward and within the lower right anterior nasal cavity. She underwent surgery by anterior rhinoscopy and endoscopic guidance. The patient\'s symptoms were resolved completely post-operatively and remained symptom-free for 18 months postoperatively.
CONCLUSIONS: Ectopic intranasal tooth is a rare phenomenon, with a male predominance and around half of all patients are diagnosed before adulthood. Ectopic intranasal tooth arising from inferior turbinate is very rare. No clear etiological factor has been suggested in most of the reported cases. Idiopathic etiology has been described as an etiologic factor for ectopic teeth. The treatment of intranasal teeth is early surgical extraction to alleviate the symptoms and prevent the possible morbidities.
CONCLUSIONS: Intranasal teeth are a rare form of ectopic teeth encountered to otolaryngology clinic and may cause a variety of symptoms and complications. CT is very useful; it confirms the diagnosis and facilitates surgical planning. Early diagnosis and treatment are very important to avoid their possible complications.

BACKGROUND: The authors\' aim in this systematic review was to evaluate to what extent impacted canines are associated with root resorption (RR) of the adjacent tooth by using cone-beam computed tomography.
METHODS: The authors performed an open-ended electronic search of the Cochrane Library, Latin American and Caribbean Health Sciences Literature, PubMed (MEDLINE), Scopus, and Web of Science and a partial gray literature search by using Google Scholar, Open Grey, and ProQuest. The authors included studies in people (adolescents, adults, and older adult) with impacted maxillary permanent canines in which the investigators assessed the incidence of RR in adjacent teeth. The investigators detected RR by using cone-beam computed tomography. Two reviewers independently performed the study selection, data extraction, and risk of bias assessment with no language restrictions. The selection criteria included observational studies.
RESULTS: From the 953 studies recorded in databases, the authors included 18 studies. The meta-analysis results revealed that the most frequent position of impacted canines was 56.99% palatal (95% confidence interval [CI], 47.032% to 66.673%); the apical one-third was the most prevalent one-third for RR (56.87%; 95% CI, 38.880% to 73.628%). The intensity of RR was slight (43.2%; 95% CI, 35.229% to 51.352%), although 30.9% (95% CI, 19.007% to 44.261%) of RR was severe. Although the studies had different sample sizes, the main methodological problem was the absence of a control group and follow-up.
CONCLUSIONS: RR in maxillary incisors was correlated with their contact with maxillary canines during eruption. Delayed eruption or treatment of impacted canines may lead to resorption of the adjacent lateral and central incisors. All root levels and surfaces of teeth associated with impacted maxillary canines can be resorbed to different levels of severity, but the apical one-third with slight resorption is the most common.
CONCLUSIONS: Knowing to what extent impacted canines are associated with root resorption of the adjacent tooth before starting any intervention, and being able to share this information with the patient, caregivers, or caregivers and patient, allows the choice of the most appropriate treatment.

Dentigerous cysts are the most common type of developmental odontogenic cysts arising from the crowns of impacted, embedded, or unerupted teeth. They constitute about 20% of all epithelium-lined cysts of the jaws. The teeth involved most often are mandibular third molar and maxillary canines. About 70% of dentigerous cysts occur in the mandible and 30% in the maxilla. Dentigerous cysts associated with ectopic teeth within the maxillary sinus are fairly rare, and only 20 cases had been reported in Medline since 1980. In the present paper, we report an additional case of dentigerous cysts associated with ectopic third molar in the right maxillary sinus. Also, pathogenesis of ectopic tooth, role of advanced imaging, differential diagnosis, and management are discussed.
