Summary Background Study design Objectives Methods Results Main limitations Conclusions Dentigerous cysts are well‐known congenital defects in horses, and the literature on this condition is extensive. Recently, a third type of dentigerous cyst, associated with an exostosis arising from the temporal bone, has been described. Today, computed tomography (CT) is often available and provides detailed information about the exact location and extent of dentigerous cysts, allowing for the description of new findings.This is a case series outlining the clinical, radiographic and computed tomographic features of dentigerous cysts in seven horses presented to the Equine Clinic at the Vetsuisse Faculty, University of Zurich, Switzerland.The aim of this case series was to describe the radiographic and computed tomographic findings, and the occurrence of exostoses arising from the temporal bone, in horses with dentigerous cysts.The medical records of the Equine Hospital at the University of Zurich were reviewed for horses admitted with dentigerous cysts between 2007 and 2023. Data collected and analysed included patient signalment, clinical history, clinical signs and their duration prior to referral, diagnostic imaging results, treatment and outcomes.The most common location for the cysts was the base of the ear, although in one case, the maxillary sinus was involved. Of the seven cases, four were Icelandic horses. CT proved superior to standard radiography for determining the extent and precise location of the cysts, as well as for identifying dental material and exostoses in the temporal region. CT also facilitated detailed surgical planning. All cysts were surgically removed with good long‐term outcomes.Overall, the incidence of dentigerous cysts in horses was low. The relatively high occurrence of dentigerous cysts in Icelandic horses in this study is an interesting finding, though the small sample size calls for further research.Two of the cases in this series were similar to a recently described variant of a ‘temporal dentigerous cyst associated with an exostosis in the temporal region’ and were closely connected to the bony structure and draining tract.

Ectopic teeth, growing in abnormal locations like the maxillary sinus, are rare occurrences, with uncertain causes including trauma, infection, and developmental abnormalities. They often appear in the second or third decade of life, sometimes without symptoms. They are often missed as symptoms can mimic chronic sinusitis but may include sinonasal issues like obstruction and facial pain. Complications ranging from recurrence to potential blindness or carcinoma have been reported. Diagnosis involves radiographic imaging, with CT scans providing precise localization. Following accurate diagnosis, treatment typically involves surgical removal, with endoscopic procedures gaining popularity due to reduced risks. Follow-up for asymptomatic cases can be conducted through periodic radiographs. We report a case of maxillary ectopic tooth as an incidental finding in an asymptomatic patient presenting to the emergency department with head trauma.

Ectopic teeth are an eruption disorder in which teeth are located in anatomical structures where, physiologically, they should not occur. An ectopic tooth is a very rare phenomenon, affecting approximately 0.5% of the canine population, and few descriptions of the treatment of such teeth in dogs can be found in the available literature. This article describes the diagnostic and therapeutic handling of cavities following extraction of ectopic teeth in nine dogs. The cases are subdivided into uncomplicated (when the ectopic tooth was encapsulated in the surrounding connective tissue, without lysis of the bone around the tooth) and complicated (in which, in addition to the presence of the ectopic tooth, a dentigerous cyst had formed). Four cases of complicated ectopic teeth are described in more detail. In this study, special attention was paid not only to the technique of tooth extraction itself but also to the method of securing and healing large bone defects after the extraction using hydroxyapatite curdlan polymer. Owing to the plastic properties of the bone substitute preparation, it was possible to implant the material without enlarging the bone defect created during the tooth extraction. Control radiographs showed features of bone regeneration, and clinical examination at both the early and late stages revealed no postoperative complications. [ABSTRACT FROM AUTHOR]

Abstract Background Dentigerous cysts are the second most common form of a developmental cyst. These cysts might be the cause of ectopic teeth. Dentigerous cysts associated with ectopic teeth in the maxillary sinus are seldom seen in clinical practice. Case presentation We reported a 23-year-old woman who presented with nasal obstruction and facial pain on the left side 4 months ago. Three courses of antibiotics and analgesia were prescribed for her without improving the presenting features. Furthermore, extraction of the left upper second premolar and second molar, but the condition persisted. An orthopantogram and computerized tomography scan revealed the ectopic position of the left third upper molar tooth, which was embedded in a cystic lesion occupying the whole maxillary sinus. Removal of the cystic lesion with the ectopic tooth was performed with a Caldwell-Luc procedure. The histopathological evaluation confirmed the diagnosis of a dentigerous cyst. The presenting symptoms were resolved following surgery with no intra- or postoperative complications. Conclusion We are reporting another case of a dentigerous cyst occupying the whole left maxillary sinus with an ectopic left third upper molar tooth. Reporting such a case will enrich the literature regarding this rare clinical entity.

Ectopic mandibular third molar is an uncommon condition, and the information regarding its causes and characteristics are not completely clarified. This article aims to report three extremely rare cases of asymptomatic ectopic mandibular third molars in the ramus of the mandible which were found accidentally during regular dental treatment. The treatment for asymptomatic impacted ectopic mandibular third molars without any pathologic related condition should be in a conservative manner without surgical intervention, but radiographic annual follow-up is indicated with monitoring for the development of any pathology.

Summary: A 3‐year‐old Comptois gelding with a history of chronic fistulation at the base of the right ear was referred for the treatment of a unilateral ectopic tooth in the right temporal region. Cone‐beam computed tomography (CBCT) confirmed the presence of an ectopic tooth in the right mandibular fossa. The ectopic tooth was associated with a draining tract running through the zygomatic process of the right temporal bone. A total mandibular condylectomy provided a direct approach to the ectopic tooth, which was subsequently successfully removed. Long‐term follow‐up confirmed a satisfactory outcome despite the need for repeated debridement and persistence of a small draining tract 15 months postoperatively. Computer‐assisted surgery (CAS) provided precise anatomical intraoperative orientation for the condylectomy and subsequent removal of the ectopic tooth close to the calvarium. The use of CAS greatly facilitated surgery and minimised the risks of important collateral damage. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Ectopic tooth in nondentate areas is uncommon. Odontogenic keratocyst arising from impacted tooth in the inferior border of orbit is very rare. This article reports the case of a 22-year-old female with odontogenic keratocyst arising from an impacted left maxillary third molar in the inferior border of the orbit causing symptoms of chronic sinusitis. The patient also had myasthenia gravis which confounded the diagnosis. The cyst was surgically enucleated along with the tooth which relieved the symptoms of the patient. [ABSTRACT FROM AUTHOR]

Rationale: 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. Patient Concern: 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. Diagnosis: Chronic generalised periodontitis with an impacted tooth in the right condylar region. Intervention: Extraction of Grade III mobile 17 and conservative treatment for ectopic molar in the condylar region. Outcome: The patient is on regular follow-up with no similar complaints. Take-away Lesson: 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. [ABSTRACT FROM AUTHOR]

Impacted canines may pose a functional and an esthetic problem for patients and can affect neighboring incisors. The aim of the study was to compare different treatment methods and their outcomes for impacted maxillary and mandibular canines. The authors included 102 patients with 118 impacted canines (82 maxillary and 36 mandibular canines). Impacted canine were confirmed during clinical and radiologic examinations. Eighty-five patients (83%) with 97 impacted canines started the treatment. The authors analyzed treatment types and outcomes. Two maxillary and 4 mandibular canines were scheduled for extraction. Orthodontic extrusion was used most frequently to treat impacted maxillary canines (89%), whereas orthodontic extrusion and transalveolar transplantation were performed most frequently in impacted mandibular canines (33% and 37.5%, respectively). The treatment was successful in 96% of the maxillary and 95% of the impacted mandibular canines. Different methods were used for impacted maxillary and mandibular canines, but their overall success rate was high. Successful outcome is determined via a well-planned and carefully executed orthodontic and surgical treatment. Early diagnosis is pivotal in facilitating spontaneous canine eruption and implementing transalveolar transplantation in a timely way. [ABSTRACT FROM AUTHOR]

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.

Ectopic nasal tooth is a rare phenomenon with only 0.1%–1% incidence rate. They are more frequently found coupled with cleft lip and palate. Here, we present a case of intranasal tooth in a 12-year-old male child with operated cleft lip and palate. The condition was diagnosed only on the basis of intraoral periapical radiograph and was extracted using gauge-holding forceps at a rural health-care center. We discuss the possible etiology, clinical findings, diagnosis, and treatment modalities of this condition. The purpose of this paper is to highlight that this rare condition can be managed with minimum available equipment in a rural setup.

Supernumerary teeth are those that form in excess to the normal dental formula and while there is no clear pathogenesis for their formation, they are known to vary in size, morphology, location and presentation. We present two cases of otherwise healthy patients who presented with pain, discomfort and discharge from the nasal passages. CT imaging identified a tooth-like density present in the bone of the nasal floor in both patients. In both cases, the tooth was extracted surgically under anaesthetic. A symptomatic supernumerary in the nasal floor might cause a plethora of symptoms and complications, decreasing the overall quality of life for a patient. Patients who present with a supernumerary tooth in the nasal floor should be further investigated with a simple nasal speculum examination and a CT scan. Their surgical management is simple and brings near immediate relief of symptoms. [ABSTRACT FROM AUTHOR]

Intranasal tooth is a rare type of supernumerary teeth. Its aetiopathogenesis is uncertain but genetic predisposition, trauma and infection are described in previous literatures. It can be either symptomatic or asymptomatic. In our case report, it was asymptomatic which was diagnosed mainly by CT scan as a radiopaque lesion with morphology and attenuation same as that of intraoral tooth. We report a case of an incidental intranasal supernumerary tooth in a 45-year-old male who presented with history of road traffic accident and parasymphyseal fracture of left mandible. This case highlights the rarity of this entity.

The aim of this case report is to present an original conservative technique for the transnasal endoscopy-assisted extraction of an ectopic upper third molar associated with a dentigerous cyst occupying the whole maxillary sinus by means of combined lower and middle meatotomies. The proposed technique is a viable, minimally-invasive alternative to the Caldwell–Luc operation (with or without the repositioning of a bone lid), and also to endoscopic middle meatal antrostomy in cases where this would be unable to ensure adequate access because of the position and size of the ectopic tooth and associated cyst.

Dentigerous cyst is known to be caused by the accumulation of fluid between the epithelium and the crown of an unerupted tooth. Its size increases by the expansion of the follicle, and it is attached to the neck of the tooth. These cysts are often associated with impacted third molars and maxillary canines and rarely with supernumerary teeth. In the present paper, we report a case of a dentigerous cyst associated with an impacted ectopic supernumerary tooth. This cyst was missed initially due to a failed root canal treatment associated with the nonvital maxillary central incisor. This case of a cystic lesion can create a dilemma between radicular and dentigerous cyst. The pathogenesis of the ectopic tooth, differential diagnosis, and management are also discussed.

Local anaesthetic is a key tool for all dentists in achieving painless treatment. Many complications have been reported secondary to a dental local anaesthetic, however those pertaining to the orbit and ocular muscles have been infrequent. This article describes three incidents when inadvertent abducens nerve palsy secondary to a dental local anaesthetic occurred during removal of an upper wisdom tooth, resulting in paresis of the lateral rectus muscle and diplopia. The patients were reassured and managed conservatively and there were no long‐term complications. The anatomical course of the abducens nerve from its origin to the lateral rectus muscle are discussed as well as potential mechanisms for the dental local anaesthetic to impact upon the nerve. Finally, following input from Opthalmology colleagues, recommendations for appropriate management are made to ensure a good outcome. [ABSTRACT FROM AUTHOR]

Abstract Background Ectopic mandibular third molar is a rare clinical entity with incompletely known etiology. Here, we sought to delineate its epidemiological, clinical and radiographic characteristics, and therapy by integrating and analyzing the cases treated in our institution together with previously reported cases. Method A new definition and classification for ectopic mandibular third molar was proposed based on its anatomic location on panoramic images. Thirty-eight ectopic mandibular third molars in 37 patients and 51 teeth in 49 patients were identified in our disease registry and from literature (1990–2016), respectively. These cases were further categorized and compared according to our classification protocol. The demographic, clinicopathological and radiographic data were collected and analyzed. Results These ectopic teeth were categorized into four levels, 33 in level I(upper ramus), 32 in level II (middle ramus), 15 in level III (mandibular angle) and 9 in level IV (mandibular body). The common clinical presentations included pain, swelling and limited mouth opening, although sometimes asymptomatic. Most teeth were associated with pathological lesions. Treatments included clinical monitor and surgical removal by intra- or extraoral approach with favorable outcomes. Clinical presentations and treatment options for these teeth were significantly associated with their ectopic locations as we classified. Conclusions Ectopic mandibular third molars are usually found in patients with middle ages and in upper and middle ramus of mandible. Surgery is preferred to remove these ectopic teeth and associated pathologies when possible.

Ectopic tooth eruption in a non-dental area is a rare entity, and is most common in oral cavity. There have been a few case reports of teeth erupting in mandibular condyle, chin, palate, coronoid process, and maxillary sinus. Ectopic tooth in the maxillary sinus are found incidentally on routine radiological examination, same time they can be symptomatic and associated with pathologies usually dentigerous cyst or odontogenic keratocyst. Facial pain, purulent rhinorrhoea, epistaxis, headache, swelling, and epiphora-related naso-lacrimal duct obstruction can also be seen. By Caldwell-Luc procedure the ectopic teeth within the maxillary sinus are often removed. In this study, a case of ectopic maxillary third molar tooth on right maxillary sinus is presented.

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. [ABSTRACT FROM AUTHOR]

Highlights • Ectopic teeth are commonly seen in palate. • The pathogenesis of ectopic teeth eruption is not fully recognized. • In children, intranasal ectopic teeth occur more frequent in patients with cleft lip and alveolus. • Most cases of the ectopic tooth are asymptomatic and identified incidentally. • The management of the ectopic teeth is tooth extraction. Abstract Introduction 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. Presentation of case 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. Discussion 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. Conclusion 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. [ABSTRACT FROM AUTHOR]

Odontogenic keratocyst is an aggressive cystic lesion and a common type of tooth derived cyst due to presence of odontogenic epithelial remnants in different regions of jaw. In majority of cases, it is located in mandibular posterior region. But it can also be found in the maxilla especially in the canine region. We present a rare case of OKC in maxillary sinus which associated with ectopic third molar. Also, it can be easily confused with other lesions of maxillary sinus like sinusitis or antral polyps, which usually resemble symptomatically. There can be malignant transformation of this benign condition towards squamous cell carcinoma or ameloblastoma. So an early and accurate diagnosis of odontogenic keratocyst is a challenge for pathologists. [ABSTRACT FROM AUTHOR]

Objective: Impacted teeth are important for plastic surgeons that frequently perform maxillofacial operations because of their tendency to affect dental occlusion, and thus, cephalometric results. Moreover, severe complications are also caused by the tooth and its surgical removal. In this study, retrospective analysis of 242 extracted teeth and 24 extracted roots was performed and an algorithmic approach to different types and the localizations of impacted teeth was presented. Possible complications and salvage procedures were also discussed. Material and Methods: A retrospective analysis of 128 patients who underwent impacted teeth removal surgery between 2013 and 2015 was performed. Mean age was 26 years (Range: 18–42 years), and the female to male ratio was 39/89. Sixteen of the patients were operated under regional nerve block, whereas the remaining were operated under general anesthesia. In 107 patients, the whole tooth was removed, whereas the residual root of the tooth was removed in 21 patients. In 89 patients, bone interventions like the creation of bone window or peridental milling to loosen the tooth were needed, whereas only oral mucosal incisions were performed in the remaining patients. Results: The most common onset symptom was localized pain, and the most common complications were swelling and edema. The most common extracted tooth was the mandibular 3rd molar. Lower lip hypoesthesia, which was continued up to eight months, was encountered in six patients who underwent mandibular 3rd molar extraction. Conclusion: In our opinion, a wide range of possible complications secondary to impacted teeth surgery makes them important for plastic surgeons who are more experienced than other disciplines, and learning teeth extraction is essential to learn in plastic surgery specialty training.

Background: Ectopic eruption of a tooth or osteoma rarely occurs within the maxillary sinus. Coexistence of these two rare entities in the maxillary sinus has never been reported in the English literature. Case Report: Herein, we present a 21 year-old male patient with osteoma and ectopic tooth in the left maxillary sinus treated with the removal of the ectopic tooth by endoscopic sinus surgery and excision of the osteoma by the Caldwell- Luc procedure. Conclusion: Unique coexistence of two different entities in the maxillary sinus is most likely due to pediatric facial trauma. Pediatric patients with maxillofacial trauma should be carefully watched for dental injury both clinically and radiologically.

The eruption of tooth other than the alveolar arch is called Ectopic Tooth. It is frequently encountered in the maxillary sinus. Facial pain is the most common presentation which is commonly misdiagnosed as chronic sinusitis. We present a case of a 47-year-old lady who was incidentally diagnosed to have an ectopic free lying canine in the maxillary sinus and discuss the various theories mentioned in literature predisposing to this condition.

Dentigerous cysts are the most common type of benign odontogenic lesions that associated with the crown of an unerupted or impacted tooth. They constitute the second most common cystic lesion of the jaws, after radicular cysts. Dentigerous cyst surrounding impacted teeth often displace these teeth into ectopic positions. Ectopic eruption of teeth into regions other than the oral cavity is common but dentigerous cysts associated with ectopic teeth within the maxillary sinus are fairly rare. The diagnosis is usually made by panoramic radiography. Cone beam computed tomography (CBCT) is indicated when an ectopic tooth is associated with an antral mass and prior to surgery. The standard treatment for a dentigerous cyst is enucleation and extraction of the cyst-associated impacted or unerupted tooth. We report CBCT findings of two cases of dentigerous cyst associated with an ectopic tooth in the maxillary sinus and review the literature reports of this condition over the past 34 years.

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. Practical Implications. 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.

Background: The etiology of ectopic third molars located in the sigmoid notch of the mandible is unclear. Only a few cases have been reported. The aim of this article is to discuss the etiology as well as treatment options and diagnostic imaging techniques. Methods: A PubMed and Medline search of the literature from 1965 to 2015 to ectopic third molars in the mandibular notch was performed. Furthermore, a clinical case provided by the authors is reported. Results: Among the eight reviewed cases, two male and six female patients were affected that ranged from 25 to 62 years of age (mean 48.4). Pain and swelling in the preauricular region or trismus but also the absence of symptoms was reported. Only in two of the summarized articles an extra-oral access for the removal of the tooth was used. The etiology seems to be individually different, however dentigerous cysts and chronic inflammation seem to play an important role in their appearance. While previous diagnostic reports described two-dimensional diagnostic imaging, currently the three-dimensional imaging is common for preoperative surgical planning with respect to removing ectopic molars. Conclusions: Ectopic third molars in the mandible are a rare condition. The etiology seems to be individually different. Nowadays, three-dimensional imaging is common for preoperative surgical planning. [ABSTRACT FROM AUTHOR]

While previous diagnostic reports described two-dimensional diagnostic imaging, currently the three-dimensional imaging is common for preoperative surgical planning with respect to removing ectopic molars. Conclusions: Ectopic third molars in the mandible are a rare condition. The etiology seems to be individually different. Nowadays, three-dimensional imaging is common for preoperative surgical planning. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

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.
