RESUMEN
Ectopic eruption of the second permanent molar is a tooth replacement disorder during adolescence. If not treated in time, it can cause hard tissue of the adjacent first molar resorption, early tooth loss, decreased chewing efficiency, and other serious malocclusions. Timely detection and treatment of ectopic eruption of the second permanent molar are of great significance in preventing malocclusions in adolescents and establishing normal occlusion relationships. However, current case reports on the ectopic eruption of the mandibular second molar are relatively rare and are mostly concentrated on surgical and orthodontic treatments, and long-term follow-up is lacking. This paper reports a case in which brass wire ligation was used to treat ectopic eruption of the mandibular second permanent molar, allowing the permanent teeth to erupt smoothly and establish a normal occlusion. The patient was observed for five years after the operation. The occlusion was stable, and the tooth root development, pulp vitality, and periodontal conditions were normal. This paper provides a clinical approach that is short in treatment duration, simple, and minimally invasive for young mandibular second permanent molars with moderate mesial inclination and partial eruption. This method is of importance in helping children establish physiological occlusion.

BACKGROUND: The proper development of the dental arches, including the eruption and correct positioning of the canines in the arch, is essential for the oral health of growing patients. Impacted canines not only give rise to functional challenges but also pose esthetic issues for patients. The aim of this article is to show if it is possible to benefit from the exclusive use of transparent aligners to guide the eruption of ectopic upper canines into the arch in the correct position. CASE REPORT: The subject of the study is the clinical case of a 13-year-old female growing patient who presented displaced upper permanent canines located in the palatal ectopic site. Following the surgical extraction of the retained deciduous elements, treatment with aligners for repositioning the ectopic canines in the arch was performed in two phases. At the end of the treatment, a Class I canine was achieved with satisfactory repositioning of the upper canines in the arch. CONCLUSION: The use of transparent aligners makes it possible, with some procedural precautions and in carefully selected cases, to reposition the ectopic palatal canines in the dental arch using a treatment that is both esthetic and effective.

The eruptive deviation of the permanent maxillary canine must be identified early, at the beginning of the second transitional period of the mixed dentition. Acting at this moment is fundamental for its spontaneous redirection and eruption. The aim of the paper is to present a case where the extraction of the deciduous canines was the choice for redirecting the maxillary permanent canines with eruptive palatal deviation, as well as to suggest a sequence of procedures for diagnosis and choice of treatment. The success of deciduous canine extraction in redirecting the ectopic permanent canines is discussed in this case, as well as aspects that might lead to failure. Still, it highlights the importance of computed tomography for choosing conservative treatment or traction, including it in the sequential guideline for acting in these cases.

Los terceros molares heterotópicos son dientes que se encuentran incluidos en los maxilares y la mandíbula distantes a su sitio de erupción habitual. Su etiología no está bien definida y existen diversas teorías. Estos dientes pueden aparecer en diferentes zonas de las estructuras óseas, teniendo predilección por la mandíbula. Suelen aparecer entre la segunda y la séptima década de la vida, la mayoría de los casos son hallazgos imagenológicos en la consulta odontológica. El tercer molar mandibular es el diente que presenta heterotopía con mayor frecuencia, siendo su localización habitual en rama mandibular y en la región subcondílea. El quiste dentígero es la patología asociada más común. Presentamos un caso de tercer molar heterotópico en rama mandibular derecha de larga evolución, relacionado a un quiste dentígero, el cual se manejó bajo anestesia regional. Se describe la etiología, técnica quirúrgica y consideraciones especiales relacionados con los dientes heterotópicos (AU)
Heterotopic third molars are teeth that are embedded in the maxilla and mandible, remote from their usual eruption site. Its etiology is not well defined and there are various theories at the moment. These teeth can appear in different areas of the bone's structures, having a predilection for the jaw. They usually appear between the second and seventh decade of life, and in most cases are imaging findings. The mandibular third molar is the tooth with the most frequent heterotopia, being its usual location in the mandibular branch and in the subcondylar region. The dentigerous cyst is the most common associated pathology. We present a case of a long evolution heterotopic third molar in the right mandibular branch, related to a dentigerous cyst which was managed under local anesthesia. The etiology, surgical technique and special considerations related to heterotopic teeth are described (AU)

Ectopic eruption results from a disturbance in tooth development and eruption, leading to an erupted or non-erupted tooth being in an unexpected anatomical location. This retrospective case series describes the location, position, form, and clinical signs associated with ectopic eruption in dogs. Thirty-five dogs (46 teeth) were diagnosed with ectopic eruption at three clinical practices during 2017-2020. The cases were described in terms of the location, the development and eruption status, the clinical signs, the consequences, and the treatment performed. The collected data were statistically analyzed to establish possible ramifications. The results showed that the ectopic eruption in the evaluated cases involved permanent teeth, mainly located in the maxilla, and mostly unerupted. Those located in the mandible were significantly more impacted than those located in the maxilla. This study concluded that tooth crowding and malocclusion (39.1%), facial swelling (8.6%), and periodontal disease (8.6%) were associated with the presence of ectopic eruption, and consequently, treatment was required in the majority (65.2%) of cases.

Dentes ectópicos são frequentemente encontrados, entretanto, terceiros molares inferiores ectópicos são inco-muns, com etiologia obscura e pouco descritos na literatura pertinente. Sua localização já foi relatada nas regiões condilar, subcondilar, incisura mandibular, ângulo e borda inferior da mandíbula. Devido à importância do plane-jamento terapêutico, manejo adequado e variedade das manifestações clínicas desta condição, este trabalho teve como objetivo relatar um caso clínico de terceiro molar inferior ectópico na região de incisura mandibular, com radiolucência aumentada ao redor da coroa, em um paciente do gênero masculino, de 28 anos e sem sintomato-logia. Acompanhamento radiográfico pode ser indicado, no entanto, em pacientes sintomáticos ou com alterações patológicas associadas, a extração deve ser considerada. Diante disso, o tratamento de escolha foi a extração do dente 38 sob anestesia geral, por via intraoral, tendo em vista a posição dentária, radiolucência e morbidade as-sociada à cirurgia. O tecido mole circundante foi enviado para análise anatomopatológica. O paciente evoluiu sem intercorrências durante avaliação pós-operatória (AU)
Ectopic teeth are frequently found, however, ectopic lower third molars are uncommon, with obscure etiology and little described in the pertinent literature. Its location has been reported in the condylar, subcondylar, mandibular notch, angle and lower edge of the mandible. Due to the importance of therapeutic planning, adequate manage-ment and variety of clinical manifestations of this condition, this study aimed to report a clinical case of an ectopic lower third molar in the region of the mandibular notch, with increased radiolucency around the crown, in a male gender pacient, 28 years old and without symptoms. Radiographic follow-up may be indicated, however, in symp-tomatic patients or patients with associated pathological changes, extraction should be considered. Therefore, the treatment of choice was the extraction of tooth 38 under general anesthesia, intraorally approach, considering the dental position, radiolucency and morbidity associated with the surgery. The surrounding soft tissue was sent for anatomopathological analysis. The patient evolved uneventfully during the postoperative evaluation (AU)

OBJECTIVES: To compare treatment time, patients' perceptions during orthodontic treatment, dental fear and side effects, between open and closed surgical exposures in patients with palatally displaced canines (PDCs). TRIAL DESIGN: Multicentre, randomized controlled trial, with random 1:1 allocation of two parallel groups. MATERIALS AND METHODS: One hundred and twenty patients from three different orthodontic centres were randomized into one of the two intervention arms, open or closed surgical exposure. Both techniques had mucoperiosteal flaps raised and bone removed above the PDCs. In open exposure, tissue was removed above the canine, and glass ionomer - reaching above soft tissue - was built on the crown. The canine was then left to erupt spontaneously, prior to orthodontic alignment. At closed exposure, a chain was bonded to the canine and orthodontic traction was applied under the mucosa until eruption. Orthodontic alignment of the canines was undertaken after eruption into the oral cavity, with fixed appliances in both groups. All participants were treated according to intention to treat (ITT). BLINDING: Due to the nature of this trial, only outcome assessors could be blinded to the intervention group. RESULTS: One hundred and seventeen patients completed the trial. All PDCs were successfully aligned. Total treatment time was equal in the two techniques, mean difference -0.1 months (95% CI -3.2 to 2.9, P = 0.93). The closed group experienced more pain and discomfort during the active orthodontic traction. Dental fear, root resorption and periodontal status did not show any clinically significant differences between the groups. GENERALIZABILITY: Results of this randomized controlled trial (RCT) can be generalized only to a similar population aged 9-16 years, if exclusion criteria are met. CONCLUSION: The closed exposure group experienced more pain and discomfort mostly during active orthodontic traction. All other studied outcomes were similar between the two exposure groups. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, ID: NCT02186548 and Researchweb.org, ID: 127201.

BACKGROUND/AIM: Numerical aberrations of permanent dentition and dystopic tooth eruption are part of the phenotype of the tumor predisposition syndrome neurofibromatosis type 1 (NF1). In these cases, surplus tooth germs usually develop in the alveolar processes of the jaw. This report attests to the dystopic development of a dysplastic supernumerary tooth in NF1 arising outside the jaw. CASE REPORT: The 8-year-old male patient developed a microdont outside the bone and above the occlusal plane of the retained maxillary right second molar. The supernumerary tooth was completely embedded in oral soft tissue. Hyperplastic oral soft tissue in the molar region and microdont were excised. Specimen of the mucosa surrounding the teeth was interspersed with diffuse and plexiform neurofibroma. The retained upper right first molar emerged spontaneously within a few months after surgery. The upper right second molar did not change position. CONCLUSION: Odontogenesis can take place within tumorous oral mucosa in NF1. Surgical removal of the tumorous mucous membrane facilitates tooth eruption in some cases.

Ectopic maxillary third molars (EMTM) are extracted mainly by the Caldwell-Luc technique but also by nasal endoscopy. There is currently no consensus on the treatment of this eruption and its management is heterogeneous and multidisciplinary. Two literature searches were performed with no time restrictions via Pubmed. In the first, we used the keywords "ectopic AND third molar" and in the second the keywords "dentigerous cyst AND ectopic third molar". For both articles, epidemiological, symptomatic, radiological and surgical data were recorded. Overall, 33 eligible articles were identified involving 39 cases of EMTM. 79% of patients were symptomatic. 87% of the teeth were associated with a dental cyst. In only 13% of cases was the location of the tooth in the sinus specified in the three planes of the space. Surgery was performed in 77% of patients by the Caldwell-Luc technique, by nasal endoscopy in 10% and by the Le Fort I approach in 3%. The indications for avulsion of EMTM are symptomatic patients or asymptomatic patients with an associated cyst. The intra-sinusal location of the tooth is not a factor in the choice of technique used, which depends rather on the individual skills of the surgeon. Although for a trained operator the Le Fort I osteotomy is an easy procedure, its interest in the treatment of EMTM is limited owing to the rare but potentially severe complications involved.

Los terceros molares heterotópicos son órganos dentarios que se encuentran en un sitio anatómico fuera de lo habitual, pueden ser supernumerarios, deciduos o un diente permanente, el cual ha sido reportado en diferentes posiciones, incluyendo la región coronoidea, cavidad nasal, seno maxilar, región orbitaria, palatina, cóndilo mandibular. La etiología de la erupción heterotópica/ectópica es desconocida, aunque hay varias teorías como la discrepancia óseo-dentaria por la evolución. Los órganos dentarios heterotópicos/ectópicos son comunes en la mandíbula y en el género femenino y pueden ocurrir en ambas denticiones. Algunos terceros molares heterotópicos/ectópicos son asintomáticos durante el periodo de vida y son usualmente detectados en hallazgos clínicos y radiográficos de manera incidental. Existen casos documentados desde 1887 hasta la actualidad cuya localización es en el reborde orbitario. En el presente artículo se expone un caso clínico de una extracción quirúrgica de un tercer molar superior heterotópico en el reborde orbitario descrita bajo el protocolo de las retenciones dentales. Dicho caso fue establecido en el Hospital Regional «General Ignacio Zaragoza¼ del ISSSTE en la Ciudad de México, con el que se obtuvieron resultados favorables, fue el primer reporte de la literatura en México. Se realizó una revisión aleatoria de la literatura en páginas como PubMed, ScienceDirect y Springer, Cochrane Library y se desarrolló el reporte de caso clínico de una paciente con un tercer molar superior heterotópico ubicado en el piso de órbita derecho (AU)
Heterotopic third molars are dental organs that are in an anatomical site out of the ordinary, can be supernumerary, deciduous or a permanent tooth, which has been reported in different positions, including the coronoid region, nasal cavity, maxillary sinus, orbital region, palatal, mandibular condyle. The etiology of the heterotopic/ectopic eruption is unknown, although there are several theories such as bone-dental discrepancy due to evolution. The heterotopic/ectopic teeth are common in the jaw and in the female gender and can occur in both dentitions. Some heterotopic/ectopic third molars are asymptomatic during the lifetime and are usually found incidentally in clinical and radiographic findings. There are documented cases from 1887 to the present that its location is in the orbital rim. In the present article we present a clinical case of a surgical extraction of a third upper molar heterotopic in the orbital rim and that is described under the dental retention protocol established in the Regional Hospital «General Ignacio Zaragoza¼ of the ISSSTE in the City of Mexico, with which they obtain favorable results, first report of the literature in Mexico. A randomized review of the literature was made on pages such as PubMed, ScienceDirect and Springer, Cochrane Library and the clinical case report of a patient with a heterotopic upper third molar located on the floor of the right orbit was developed (AU)

INTRODUCTION: Ectopic sinonasal teeth are uncommon. The classic approach to removal of such foreign bodies was the Caldwell-Luc. In recent years however, endoscopic approaches have become increasingly utilized. Despite this, there is a dearth of literature and consensus regarding the endoscopic removal of ectopic sinonasal teeth. As such, we conducted a systematic review on all cases of endoscopic removal of ectopic sinonasal teeth in the literature. With an understanding of the literature, clinical and technical decision making for patients with this pathology may be elucidated. METHODS: Systematic review of the Ovid Medline, EMBASE Classic and Pubmed databases were conducted using PRISMA guidelines. RESULTS: Our search identified 100 articles. Final inclusion consisted of 23 studies with a total of 27 patient cases. The majority of the patients included were male (70.4%) with a mean age of 27.06 years. Patients presented with a multitude of symptoms, with nasal obstruction (48.14%), rhinorrhea (22.2%), facial pain (22.2%) and epistaxis (22.2%) being most common. Surgeons mostly reported using a 0° endoscope (22.2%) and performing a maxillary antrostomy/uncinectomy (37%) and simple extraction under general anesthetic (41%). CONCLUSIONS: This systematic review analyzed important epidemiological, clinical and technical information regarding patients with endoscopic removal of sinonasal ectopic teeth. Further research is needed to promote implementation of such data into clinical practice.

Background: Closed and open surgical techniques are two different main approaches to surgical exposure of palatally displaced canines (PDCs). Because there is insufficient evidence to support one technique over the other, there is a need for randomized controlled trials. Objectives: To compare surgery time, complications and patients' perceptions between closed and open surgical techniques in PDCs. Trial design: The trial was a multicentre, randomized, controlled trial with two parallel groups randomly allocated in a 1:1 ratio. Material and methods: Study participants were 119 consecutive patients from 3 orthodontic centres, with PDCs planned for surgical exposure, randomly allocated according to a computer-generated randomization list, using concealed allocation. Full-thickness mucoperiosteal flap was raised, and bone covering the canine was removed in both interventions. In closed exposure, an attachment with a chain was bonded to the canine and the flap was sutured back with the chain penetrating the mucosa. In open exposure, a window of tissue around the tooth was removed and glass ionomer cement placed on the canine crown, to prevent gingival overgrowth during spontaneous eruption. Patient perceptions were assessed with two questionnaires, for the evening on the day of operation and 7 days post-surgery. Blinding: It was not possible to blind either patients or care providers to the interventions. The outcome assessors were blinded and were unaware of patients' intervention group. Results: Seventy-five girls and 44 boys, mean age 13.4 years (SD 1.46) participated in the study and got either of the interventions (closed exposure, n = 60; open exposure, n = 59). Surgery time did not differ significantly between the interventions. Complications though were more severe in bilateral cases and the patients experienced more pain and impairment in the open group. Conclusion: There were no statistically significant differences regarding surgery time between the groups. Postoperative complications were similar between the groups in unilateral PDCs, but more common in the open group in bilateral cases. More patients in the open group experienced pain and impairment compared to the closed group. Trial registration: Trial registration: ClinicalTrials.gov, ID: NCT02186548 and Researchweb.org, ID: 127201.

Objectives: To investigate which surgical technique orthodontists prefer for exposing palatally impacted canines (PICs), and to compare closed exposure and glass-ionomer open exposure (GOPEX) with regard to pre- and post-surgical orthodontic variables. Materials and methods: A questionnaire with 19 questions and three cases visualising superficial, deep, or medial PICs was sent to 48 orthodontists working in a Swedish county. Sixty case records for patients with unilateral PICs from two centres were analysed; 30 patients having GOPEX (Centre A), and 30 undergoing closed exposure (Centre B). Pre- and post-surgical orthodontic variables were collected from the dental records. Results: The response rate was 81 per cent. There was an equal distribution of preference between open and closed exposure. Glass-ionomer cement (GIC) was predominately used as surgical packing in open exposure. No active traction was initiated until the canine erupted spontaneously. In the closed exposure cases, traction started shortly after exposure. The clinicians mentioned similar advantages of choosing one technique over the other and the main basis for the decision was the clinician's preference and not the location of the canine. There were no differences regarding post-exposure complications between the techniques. The overall treatment time was the same but there were fewer appointments and significantly shorter active treatment time with traction of the PIC in the GOPEX group. Limitations: Despite the homogeneity of the baseline patient characteristics, pre- and post-surgical orthodontic variables were analysed retrospectively, therefore, it is difficult to assess what impact these confounding factors may have had on the treatment time. Conclusions: The choice of exposure technique depends on the clinician's preferences. The active treatment time is shorter and the number of appointments fewer with open exposure when GIC is used as surgical packing.

Objective: To evaluate which palatally displaced canines (PDCs) benefit from interceptive extraction of the deciduous canine, to assess possible side effects from the extraction, and to analyse other dental deviations in patients with PDCs. Design, settings, participants, and intervention: A sample of 67 patients (40 girls, mean age: 11.3 ± 1.1; 27 boys, mean age ± SD: 11.4 ± 0.9) with unilateral (45) or bilateral (22) PDCs were consecutively recruited and randomly allocated to extraction or non-extraction using block randomization. No patients dropped out after randomization or during the study. The patients were given a clinical examination and panoramic radiographs were taken at baseline and after 6 (T1) and 12 months (T2). An individual therapy plan was made for the PDCs that had not erupted at T2. Measurements were performed blindly and the outcome measures were: canine position and angulation, root development, midline shift, rotation, or movement of adjacent teeth into the extraction site, and frequency of other dental deviations. Results: Interceptive deciduous canine extraction is beneficial if the alpha angle is between 20 and 30 degrees. A PDC located in sector 4 with an alpha angle >30 degrees should have immediate surgical exposure, while canines angulated less than 20 degrees and located in sector 2 can be observed without prior interceptive extraction. Deciduous canine extraction was more beneficial in younger patients with less advanced root development. Minor side effects, such as rotation or migration of teeth into the extraction space, were observed in 15 out of 35 patients. A majority of the patients had other dental deviations than PDC in the dentition. Limitations: The results are only valid for patients with no space deficiency in the maxilla and with PDCs located in sector 2-4. Harms: No harms were detected. Conclusions: The alpha angle and sector position are good diagnostic predictors of when interceptive extraction is beneficial. Minor side effects are seen after the extraction and the majority of the patients had other dental deviations too. Registration: This trial was registered at http://www.fou.nu/is/sverige, registration number: 211141.

Background: Although extraction of primary canines in the mixed dentition has been suggested as a measure to prevent impaction of palatally displaced permanent canines (PDCs), the relevant evidence has been inconclusive. Objective: To assess the effectiveness of this practice and investigate the quality of the evidence. Search methods: Search without restrictions in 15 databases and hand searching until April 2017. Selection criteria: Randomized clinical trials comparing extraction of primary canines in the mixed dentition to no treatment. Data collection and analysis: Following study retrieval and selection, data extraction, and individual study risk of bias assessment using the Cochrane Risk of Bias Tool, the random effects method of combining treatment effects was used. The overall quality of the available evidence was assessed with the Grades of Recommendation, Assessment, Development, and Evaluation approach. Results: Finally 5 studies were identified involving 214 individuals, followed for up to 48 months post-intervention. Two studies were at low and the rest at high risk of bias. Although at the 12-month evaluation, extraction of the primary canine did not result in a statistically significant difference [risk ratio (RR): 1.537; 95% confidence interval (CI): 0.656-3.601, P = 0.323; 1 study, n = 67 individuals], beyond 12 months a benefit was noted (RR: 1.784; 95% CI: 1.376-2.314, P = 0.000; 5 studies, n = 214 individuals; I2 = 0%). Analysis of the studies at low risk of bias confirmed the above-mentioned result (RR: 1.713; 95% CI: 1.226-2.394, P = 0.002; 2 studies, n = 91 individuals; I2 = 0%; moderate quality evidence). No difference was observed regarding root resorption of adjacent permanent teeth (RR: 0.602; 95% CI: 0.277-1.308, P = 0.200; 1 study; n = 67 individuals; moderate quality evidence). Conclusions: Extraction of primary canines in the mixed dentition may increase the chance of subsequent successful eruption of PDC in the long term. However, better study standardization is necessary.

BACKGROUND: Palatally displaced canines or PDCs are upper permanent canines, commonly known as 'eye' teeth, that are displaced in the roof of the mouth. This can leave unsightly gaps, cause damage to the surrounding roots (which can be so severe that neighbouring teeth are lost or have to be removed) and, occasionally, result in the development of cysts. PDCs are a frequent dental anomaly, present in 2% to 3% of young people.Management of this problem is both time consuming and expensive. It involves surgical exposure (uncovering) followed by fixed braces for two to three years to bring the canine into alignment within the dental arch. Two techniques for exposing palatal canines are routinely used in the UK: the closed technique and the open technique. The closed technique involves uncovering the canine, attaching an eyelet and gold chain and then suturing the palatal mucosa back over the tooth. The tooth is then moved into position covered by the palatal mucosa. The open technique involves uncovering the canine tooth and removing the overlying palatal tissue to leave it uncovered. The orthodontist can then see the crown of the canine to align it. OBJECTIVES: To assess the effects of using either an open or closed surgical method to expose canines that have become displaced in the roof of the mouth, in terms of success and other clinical and patient-reported outcomes. SEARCH METHODS: Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 24 February 2017), the Cochrane Central Register of Controlled Trials (CENTRAL) (in the Cochrane Library, 2017, Issue 1), MEDLINE Ovid (1946 to 24 February 2017), and Embase Ovid (1980 to 24 February 2017). The US National Institutes of Health Ongoing Trials Register (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA: We included randomised and quasi-randomised controlled trials assessing young people receiving surgical treatment to correct upper PDCs. There was no restriction on age, presenting malocclusion or type of active orthodontic treatment undertaken. We included unilaterally and bilaterally displaced canines. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the results of the electronic searches, extracted data and assessed the risk of bias in the included studies. We attempted to contact study authors for missing data or clarification where feasible. We followed statistical guidelines from the Cochrane Handbook for Systematic Reviews of Interventions for data synthesis. MAIN RESULTS: We included three studies, involving 146 participants. Two studies were assessed as being at high risk of bias.The main finding of the review was that the two techniques may be equally successful at exposing PDCs (risk ratio (RR) 0.99, 95% confidence interval (CI) 0.93 to 1.06; three studies, 141 participants analysed, low-quality evidence).One surgical failure was due to detachment of the gold chain (closed group). One study reported on complications following surgery and found two in the closed group: a post-operative infection requiring antibiotics and pain during alignment of the canine as the gold chain penetrated through the gum tissue of the palate.We were unable to pool data for dental aesthetics, patient-reported pain and discomfort, periodontal health and treatment time; however, individual studies did not find any differences between the surgical techniques (low- to very low-quality evidence). AUTHORS' CONCLUSIONS: Currently, the evidence suggests that neither the open or closed surgical technique for exposing palatally displaced maxillary canine teeth is superior for any of the outcomes included in this review; however, we considered the evidence to be low quality, with two of the three included studies being at high risk of bias. This suggests the need for more high-quality studies. Three ongoing clinical trials have been identified and it is hoped that these will produce data that can be pooled to increase the degree of certainty in these findings.

Los dientes ectópicos son órganos dentarios que se encuentran enuna región diferente a la habitual, existen publicaciones que reportanórganos dentarios ectópicos en la región maxilofacial siendo sitioscomunes el paladar, región paraorbitaria, cavidad nasal, seno maxilar, mentón, apófisis corónides y cóndilo. También se han publicado casos de zonas más alejadas como ovario o región anterior del mediastino,que por lo general están relacionados con un teratoma. En su mayoría son hallazgos radiográficos, por lo que en general son asintomáticos. Al encontrarse dentro del seno maxilar su terapéutica puede ser conservadora,bajo vigilancia clínica-radiográfi ca o quirúrgica mediante endoscopia, abordaje transnasal, Caldwell-Luc o abordaje cuadrangular. La extracción de estos órganos dentarios es necesaria por la tendencia que presentan a formar quistes, desarrollar tumores odontogénicos y desencadenar alteraciones neuropáticas. Se reporta el caso de una paciente de 32 años de edad con diagnóstico de tercer molar ectópico en región de antro maxilar.
Ectopic tooth are dental organs found in a uncomon regions. There arepublication that report ectopic tooth in the maxillofacial region beingcommon sites palate, paraorbitaria region, nasal cavity, maxillarysinus, chin, coronides process and condyle. Cases have also beenreported in non-dental areas such as ovary, anterior mediastinum regionusually related to a teratoma. Ectopic tooth are often radiographicfi ndings because they are generally asymptomatic. Its therapeuticwhen found in the maxillary sinus could be conservative under periodicclinical-radiographic vigilance. Removal of these dental organs isnecessary for their tendency to form cysts, develop odontogenic tumorsand trigger neuropathic disorders. Surgical options are endoscopic,transnasal, Caldwell Luc or quadrangular approach. We present acase of a female of 32 years old with a diagnosis of ectopic third molarin maxillary antrum.

The ectopic placement of mandibular third molars in the subcondylar region is an uncommon phenomenon. Most patients are asymptomatic but can present with acute infection or associated pathology necessitating surgical intervention. Surgical approaches have been described utilizing both extraoral and intraoral approaches to the region.This paper presents a clinical report of a patient presenting with acute fascial space infection arising from an ectopic third molar in the mandibular subcondylar region, managed with surgical removal via an endoscopically assisted intraoral approach.
