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.

Zusammenfassung. Wir berichten über einen 80-jährigen Patienten, der einen oberen Molar wegen Gesichtsscherzen entfernt hatte und im Verlauf eine Sinusitis maxillaris bei einem ektopischen Zahn entwickelte. Als Fieber und Nackenschmerzen auftraten, wurde eine eitrige Meningitis vermutet. Der unauffällige Liquor und der Nachweis im CT von typischen Verkalkungen um den Dens axis führten endlich zur korrekten Diagnose eines «Crowned Dens»-Syndroms.

Purpose: Ectopic tooth within the tooth bearing region is often noticed in clinical practice but ectopic eruption in non-dentate regions like maxillary sinus is rare. Rarer is the presence of multiple ectopic teeth involving both the maxillary incisors and canine and has not been reported yet. Method: A seventeen year old male presented with a complaints of dull pain on the right side of the face for past two years. Water’s view X-ray of PNS revealed dense non-specific opacification of the right maxillary sinus. Result: Antrostomy through Caldwell–Luc approach revealed three ectopic teeth in the right maxillary sinus. Later the teeth were identified to be central incisor, lateral incisor and canine. Conclusion: Rare finding of ectopic incisors in the maxillary sinus is reported and the need for interdisciplinary approach to patients is stressed upon.

Craniofacial duplication is a rare congenital anomaly. A case of hemi-mandibular duplication with an accessory oral cavity is presented with along with first-time reported pre- and postnatal MRI, surgical approach and a literature review. MRI clearly depicts the ectopic tooth buds and parotid aplasia in this condition, features that are diagnostic of partial facial duplication. MRI is diagnostic for this condition and can be useful to avoid misdiagnosis of a facial mass.

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.

Pulp regeneration by stem cell transplantation declines due to age-related reduction. We hypothesized that administration of a cytokine together with the cell transplantation may improve the stem cell niche microenvironment and promote regeneration. CCL11 is implicated as a factor in aging. This investigation was performed to investigate the changes in the quality of the regenerated pulp by administration of CCL11 antibody in the aged mice and elucidate the underlying mechanisms.Mobilized dental pulp stem cell (MDPSC) transplants were characterized in an ectopic tooth root transplantation model in both the aged and young mice. The amount of regenerated pulp tissue was analyzed in the transplants with continuous administration of CCL11 antibody compared with those without the antibody administration. Blood CCL11 levels were assessed at the onset of the experiment. Furthermore, immunostaining of CD68 together with CD11c or CD206 for M1 and M2 macrophage, respectively, were performed. Each double-positive cell count of M1 and M2 macrophages and M1/M2 ratio in the transplants with administration were compared with those without administration both in the aged and young mice.The administration of CCL11 antibody enhanced pulp regeneration and significantly reduced the blood CCL11 level in the aged mice. As the number of M1 macrophages decreased, the M1/M2 ratio in the treated aged mouse was less than that in the untreated aged mouse. There was, however, significant difference between the treated aged mouse and the untreated young mouse.CCL11 antibody has the potential to enhance and stimulate pulp regeneration in the aged mice.

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.

Eruption disturbances related to the position include ectopic eruption and transpositions. The occurrence of ectopic eruption is most commonly associated with maxillary incisors. The normal eruption, position and morphology of these teeth are crucial to craniofacial development, facial esthetics as well as phonetics. It is essential that the clinicians have thorough knowledge of the eruption disturbances in order to make an appropriate, as well as timely intervention, as dictated by the complexity of the problem.

Nasally ectopic teeth are rare, but can be a source of significant morbidity. Symptoms can include facial pain, nasolacrimal duct obstruction, fungal rhinitis, persistent rhinorrhea and episodic epistaxis. A nasally ectopic tooth should be considered as a differential diagnosis for a radiopaque lesion within the nasal cavity. This case illustrates the diagnosis and subsequent minimally traumatic recovery of a nasally ectopic tooth, believed to be an upper first premolar tooth, via an endoscopic approach.

A 27-year-old woman was referred to neurology from her family physician’s office for evaluation of her seizures. The patient also had chronic headaches that were refractory to standard medical treatment. She described these as unilateral (right-sided), throbbing, of moderate to severe intensity

Background: Rhinoliths are rare affections of the main nasal cavity and the paranasal sinuses. Initially, as a result of their low incidence, they are often incorrectly classified as calcified tumors in clinical examination. Methodology: We have identified three cases in our patient population and evaluated the clinical symptoms as well as the pathological findings and the causes of the disease. Results: Due to their extension and the respective clinical pattern, all masses were surgically removed under endotracheal anesthesia. The histopathological findings comprised an ectopic tooth, a vegetable (most likely a leaf from the garden) as well as a textile foreign body (probably of iatrogenic origin). Conclusion: Undiscovered foreign bodies of the main nasal cavity are a common cause for the formation of rhinoliths. We have also displayed the respective incidence and the therapeutic options.

Dental injury is one of the most common complications of tracheal intubation. Although teeth dislodged during tracheal intubation are usually found in the oral cavity, we encountered a case of a missing tooth found in the nasal cavity in an intubated patient. A 62-year-old man with 4 loose teeth in the upper jaw was scheduled for laparoscopic hernia repair. After our second attempt at insertion of a nasogastric tube via the left naris, we discovered that a tooth had been dislodged. A lateral-view radiograph revealed the dislodged tooth in the nasal cavity. The ectopic tooth was removed by an otorhinolaryngologist.

Intranasal ectopic tooth, which can be derived from either supernumerary, deciduous or permanent tooth, is generally a rare event. Their existence can cause a wide array of complication such as epistaxis, nasal blockage, nasal pain, rhinosinusitis, septal deviation, septal abscess as well as oronasal fistula. We highlight a case of a canine supernumerary tooth that erupted at floor of nasal cavity, causing an acute unilateral nasal blockage, and managed successfully with an endoscopic nasal tooth extraction.International Journal of Human and Health Sciences Vol. 03 No. 04 October’19 Page : 235-237

A 40-year-old female patient presented to ears, nose and throat complaining of cacosmia and discharge from the left maxillary sinus. Her CT scan revealed an ectopic supplemental nasal tooth which could not be removed by nasoendoscopy. Therefore, a conventional intraoral surgical approach was taken. In this case, we discuss the indications for conventional surgical removal of teeth from the nasal cavity when a nasoendoscopic approach is not possible. We highlight the potential pitfalls of both conventional and nasoendoscopic approaches, including some essential considerations when treatment planning these cases.

The presence of supernumeraries may lead to irruptive problems, such as impacted teeth, functional and aesthetic disorders. The present study describes two clinical cases, with anterior teeth eruption disorders caused by additional dental elements, treated early. Patients presented with aesthetic involvement, with delay in the emergence of the upper incisors. The clinical and radiographic examinations detected the presence of obstacles to the teeth eruption. Early treatment with 2x4 appliance was realized, followed by final corrective orthodontics. After restoration of the dimension for retained teeth, there was spontaneous eruption in clinical case 1 and need of traction in clinical case 2. When patients reached the complete permanent dentition, a corrective phase was performed with the objective of detailing the dental occlusion and finishing the treatment. The early diagnosis of teeth impacted and supernumerary, provide the achievement of adequate occlusion and positive aesthetic of patients, with good prognosis, avoiding psychological and functional problems caused by absence of anterior teeth. Keywords Interceptive Orthodontics. Supernumerary Tooth. Ectopic Tooth Eruption. ResumoA presença de supranumerários pode ocasionar problemas irruptivos, como impacção de dentes, desordens funcionais e estéticas. O presente trabalho descreve dois casos clínicos abordados precocemente, com alterações na irrupção de dentes anteriores devido a presença de supranumerários. Os pacientes apresentavam queixas estéticas, com atraso no aparecimento dos incisivos superiores. Os exames clínico e radiográfico detectaram a presença de barreiras irruptivas. Realizou-se tratamento precoce com auxílio da mecânica 4x2, seguido pela ortodontia corretiva final. Após etapa de restabelecimento da dimensão para os dentes retidos, houve irrompimento espontâneo no caso clínico 1 e necessidade de tracionamento no caso clínico 2. Quando pacientes atingiram a dentição permanente completa, realizou-se uma fase corretiva com o objetivo de detalhamento da oclusão dentária e finalização do tratamento. O diagnóstico precoce de impacção dentária e detecção de supranumerários favoreceu a restituição de oclusão adequada e estética dos pacientes, com prognóstico muito favorável, evitando problemas psicológicos e funcionais provocados pela ausência de dentes anteriores.

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.

An ectopic tooth in the nasal cavity is a rare phenomenon, especially on the inferior turbinate. In most of the reported cases, no etiological explanation of the intranasal teeth has been suggested or found. In children, intranasal ectopic teeth are usually associated with cleft lip and alveolus. Here, we report a rare case of a pediatric patient with unilateral nasal obstruction due to an intranasal ectopic tooth originating from the inferior turbinate without any facial and dental deformities. This case is unique due to the unusual location of the ectopic tooth and its presentation in a child without facial and dental deformities.

Abnormalities in tooth morphology and number are not uncommon. However, an exact clone of a normal tooth is a recondite clinical finding. Presence of supplementary teeth is mostly noticed in maxillary anterior, molar or premolar region, followed by mandibular premolar region in descending order of its site of occurrence. Supplemental tooth in mandibular anterior has a low prevalence of 0.01%. This paper reports one such rare case of nonsyndromic incisive jumeaux in mandibular anterior region during mixed dentition period.

Aim The incidence of impacted maxillary canines in Caucasians reportedly ranges from 1% to 3%. The objectives of this study were to estimate the prevalence and determine the characteristics of impacted maxillary canines in southern Chinese children and adolescents. Methods This retrospective audit involved 533 subjects with impacted maxillary canines that had been treated between February 1982 and February 2009. A customized data entry form was prepared to record and evaluate the status of impacted canines. Results The 533 subjects (327 females and 206 males) with impacted maxillary canines, who were identified from the population of 26 039 subjects, represented a prevalence of 2.1%. Four hundred and forty-two (82.9%) of these subjects had unilaterally impacted canines, while 91 (17.1%) of them had bilateral impactions. In 442 subjects with unilateral canine impactions, 220 (49.8%) were buccally placed, 194 (43.9%) were palatally placed, and 28 (6.3%) of the canines were found to lie within the arch. Conclusions The overall prevalence of impacted maxillary canines in this study of 2.1% was similar to the figures quoted for Caucasian populations. In subjects with unilateral impactions, buccally impacted canines demonstrated a slightly higher incidence (49.8%) compared to palatally impacted canines (43.9%).

Ectopic eruption of a tooth within the dentate region of the jaws is often noticed in clinical practice and is well documented in the literature. But the ectopic eruption into the non dentate region is rare and scantly documented. The maxillary sinus is one such a non dentate region, apart from nasal septum, mandibular condyle, coronoid process and the palate, to accommodate such ectopic eruptions of teeth. Due to its rarity and lack of consensus over its management, the incidence deserves to be added to the literature and discussed. Early surgical intervention for removal of ectopic tooth along with enucleation of the associated cyst, if any, is the treatment of choice.

La impactación de terceros molares en la región condilar es muy inusual. Este artículo describe el caso de cordal incluido en región subcondilar en una mujer que refirió dolor inespecífico hemifacial y varios episodios de tumefacción. Se describe el manejo quirúrgico de estas inclusiones y se realiza una revisión bibliográfica. Ectopic impaction of the mandibular third molar in the condylar region is an extremely rare condition. This report describes a case of an impacted tooth in the sub-condylar region in a woman with hemifacial discomfort and recurrent swelling. A description of the surgical management of this pathology is given as well as a literatura review.

Dentigerous cysts are commonest type of developmental, epithelial-lined, odontogenic cysts arising in the jaw from the crowns of impacted, unerupted or embedded tooth, most often third molar. But dentigerous cysts arising from ectopic tooth in maxillary sinus is quite rare. Ameloblastoma changes in the dentigerous cysts are rare and to the best of our knowledge have not been reported to be arising from ectopic tooth in maxillary antrum. In this article, we present the radiological diagnosis, clinical features and management of this rare case of ameloblastic transformation in dentigerous cyst arising from ectopic tooth in maxillary antrum.

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.

Ectopic teeth occur because of failure of the first branchial cleft to close during development and are found mostly in young horses. Such dentigerous cysts are often located at the base of the ear, forming a notable swelling with a fistula, as it was the case with the two year old Iceland mare «Runa». In order to confirm the diagnosis, x-ray images were taken, which is also necessary to locate the ectopic tooth correctly. While operating, the whole cystic membrane should be removed and it is important to prevent adjacent nerves and blood vessels from damage. Prognosis for complete healing after removing an ectopic tooth is excellent.

An intranasal tooth (INT) is an ectopic tooth erupting into the nasal cavity. It is a rare clinical entity. Ectopic and supernumerary teeth may be present in many regions of maxillofacial skeleton. Ectopic teeth may be supernumerary, deciduous or permanent. The clinical manifestations of intranasal tooth are quite variable and they may cause a variety of symptoms and complications. Their clinical and radiographic presentations are classical, posing little challenge to the diagnostician. The identification of such teeth can be important since they have potential to cause considerable morbidity. Here, we describe a case of intranasal tooth along with possible etiopathogenesis, clinical and radiographic features, differential diagnosis, potential complications and treatment modalities.

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.

A 30-year-old female patient reported to the dental clinics with a complaint of missing teeth. On clinical evaluation maxillary left pre-molars and mandibular left second molar were absent, the patient was free from any gross pathology and a set of radiographs was advised for analysis of periodontal health and treatment planning. Radiographs revealed the presence of an impacted 3rd molar tooth in the left coronoid process [Table/Fig-1], though clinically no signs or symptoms were observed. Since the location of tooth was abnormal the case was diagnosed as “ectopic 3rd tooth in coronoid process”. [Table/Fig-1]: Orthopantomogram showing ectopic 3rd molar in left coronoid process As the literature suggests such asymptomatic patients can be kept under regular follow-up without any surgical intervention till there is any associated pathology or discomfort. The patient was motivated for placement of implants in edentulous areas and was informed regarding the presence of the ectopic tooth. All the possible complications which could arise in relation to the ectopic tooth were explained to the patient. Further, the patient was advised to have a regular follow-up and visit the dental clinics in case even slight discomfort arose in the concerned region. Occurrence of impacted 3rd molar tooth is not uncommon but an impacted 3rd molar tooth in an abnormal location (ectopic tooth) is not encountered very frequently [1]. As per the reviews very few cases of ectopic 3rd molar tooth have been reported in English literature [1,2]. Hence, it becomes difficult to comment about the epidemiology of these ectopic teeth. The aetiology of this phenomenon also remains obscure, though many theories have been put forth to explain this exceptional event [2]. This paper presents a case of an ectopic tooth in coronoid process. Only 6 cases of this condition have been reported till date, thus the current case is another milestone of this rare occurrence [1]. A tooth may be impacted, by soft tissue alone or it might be a bony impaction, but the location of the tooth is close to its physiologic position [3]. When such impacted teeth have dislocated to distant regions such as condylar process, mandibular ramus, maxillary sinus, nasal cavity etc these are referred to as ectopic teeth [1,2]. Keros and Susic referred to this condition as “Heterotopic position of tooth” in his report [4]. Occurrence of ectopic tooth as such is an uncommon phenomenon and ectopic tooth in coronoid process is even rarer [1], the latter scenario was observed in the current case. It is not always possible to determine the exact cause of an ectopic tooth. Various authors have suggested different possible aetiologies which may be either pathologic such as cysts, developmental like an abnormal eruptive pattern or tooth germ development in abnormal location, or sometimes traumatic or iatrogenic in nature [1,2]. In the present case the causative factor appears to be developmental aberration since there was no associated pathology or any history of trauma or surgical interventions in relation to the jaws. Due to the sporadic nature it is not appropriate to definitively comment about the gender predilection, site, clinical signs and symptoms, etc of ectopic 3rd molars. Most of the reported cases in literature are in women and located in mandibular subcondylar or condylar region [1]. In present case too patient was a female but the tooth was located in an atypical position i.e. the coronoid process [Table/Fig-1]. The clinical symptoms may be in the form of pain and swelling, trismus or sometimes fever with acute inflammation and draining sinus [2]. In the case under discussion the patient was asymptomatic and it was an incidental finding. Asymptomatic cases are generally kept under regular follow-up with radiographic evaluation, as was done in the current case. Ectopic tooth associated with cysts are generally surgically treated conservatively until the cyst is very small. In latter case patient is kept under regular follow-up with radiographic evaluation as is done in asymptomatic cases. Intraoral approach is preferred if possible to avoid scarring of facial skin [5]. Based on various reported cases and reviews of ectopic tooth it can be said that coronoid process is not a common location for occurrence of this phenomenon. Further, it is a must that asymptomatic cases are kept under regular follow-up to monitor the development of any new symptoms or pathology or observe any increase or decrease in the associated pathology.

Dentigerous cysts associated with an ectopic third molar in the subcondylar area are fairly rare, and information is limited about its causes and characteristics. This article reports a case of dentigerous cysts associated with an ectopic third molar in the subcondylar and reviews the literature on the clinical signs and symptoms and different treatment methods of this condition. We report a case dentigerous cyst associated with an ectopic mandibular third molar in the subcondylar area. 14 cases of dentigerous cysts associated with an ectopic third molar in the subcondylar area reported in the English-language literature over the past 30 years, identified from Medline databases are also reviewed. We found a mean age at diagnosis of 48.1 years and a higher prevalence in women. Facial pain and swelling on the preauricular region or ipsilateral side of the mandible were the most common symptoms. Among the 14 case reports identified, 7 were by an extraoral approach and 7 were by an intraoral approach. The most commonly used extra-oral approaches are retromandibular. The etiology of ectopic mandibular third molars has not yet been completely clarified. They must be removed if they cause symptoms or are associ­ated with cystic pathology. The treatment of third molars in the condylar region is divided into conservative and, in most cases, surgical removal by intra or extra-oral route. The surgical approach must be carefully planned according to the location and posi­tion of ectopic third molars. Key words: Dentigerous, subcondylar, ectopic tooth.

Ektopik dişler diş ve ağız harici lokalizasyonlarda nadiren tarif edilmişlerdir. Maksiller sinüs içinde ektopik diş çıkması, asemptomatik olması nedeniyle sıklıkla rutin radyolojik ve klinik değerlendirme sırasında tesadüfen karşılaşılır. Eğer maksiller sinüs içinde ektopik diş çıkması semptomatik oluşursa; pürülan rinore, yüz ağrısı, başağrısı, şişme, epistaksis ve epifora gibi bulgular görülebilir. Çoğunlukla Caldwell-Luc prosedürü ile tedavi edilir. Bu çalışmada, sağ maksiler sinüste ektopik maksiller üçüncü molar diş olgusu sunuldu, Ectopic teeth have been rarely described in non-dental and non-oral localizations. Ectopic tooth eruption in maxillary sinus usually runs across incidentally during routine radiological or clinical evaluation because it is generally asymptomatic. If it occurs symptomaticaly; the findings like purulent rhinorrhoea, facial pain, headache, swelling, epistaxis and epiphora can be seen. It is often treated via Caldwell-Luc procedure. In this study, a case of ectopic maxillary third molar tooth on right maxillary sinus is presented.
