ABSTRACT

ABSTRACT This clinical report describes the implant rehabilitation for the treatment of pathological roots resorption due to inadequate orthodontic movement in prosthetic space reduced by means of load and immediate implants, computer-guided surgery and use of the own tooth crown in a 21-year-old-patient. The atraumatic exodontics of the right and left upper lateral incisors was performed, and then immediate placement of osseointegrated implants using the computer guided surgery technique. The crown teeth itself was used in the immediate aesthetic and functional rehabilitation. Completion of the treatment resulted in a functional and aesthetic successful outcome and a 27 months follow-up presented uneventful. The procedures included in this complex rehabilitation treatment in the esthetic zone were appropriate and essential for the maintenance of the soft and hard tissues contour and thickness ensuring the excellence in rehabilitation.

ABSTRACT

Abstract Objective To quantify the bone volume that can be safely withdrawn from 3 donor sites: (1) the mandibular symphysis, (2) the oblique mandibular line and (3) the skullcap. Methodology For the symphysis, 200 tomographic exams were evaluated by the extension of the anterior loop of mental foramen, by the nerve, by the distance of the foramens, by the distance between the vestibular cortical and the lingual plates and by the distance between the apexes, or lower anterior teeth, and the mandibular base, using the "distance" tool of the I-CAT Vision, in the panoramic and parasagittal reformations. For the oblique line, 70 TCFC exams were analyzed retrospectively in panoramic and parasagittal reformations, evaluating the thickness of the vestibular cortical and the distance between the cortical and the mandibular canal. For the cranial bone, a hexagonal donor site located in parietal area was considered. Results The average dimensions of the bone blocks that can be safely removed from the region of the mandibular symphysis are: 32.27 mm in length, 4.87 mm in height and 4 mm in thickness, providing a volume of 628.61 mm3 available for grafting. In the oblique line, the available bone volume for grafting was 859.61 mm3. In the region of the cranial vault, multiplying the average bone thickness by the area of the hexagon, an average volume of 2,499 mm3 was obtained. Conclusions Comparing the donor sites, the bone availability in the cranial vault is 3 times greater than in the mandibular posterior region, and at least 2 times greater than in the mandibular symphysis.

ABSTRACT

O objetivo desse estudo foi revisar a literatura e enfatizar os aspectos relacionados ao manejo preventivo e terapêutico da osteorradionecrose dos maxilares. Realizou-se revisão bibliográfica não sistemática, descritiva e qualitativa nas plataformas de pesquisa Scielo, Pubmed e Medline, utilizando os descritores, osteoradionecrosis/osteoradionecrose e/ou radiotherapy/radioterapia e/ou jaw/arcada maxilares. Os critérios de inclusão foram: artigos publicados em inglês, espanhol ou português, pesquisas clínicas ou relatos de casos abordando tratamento com radioterapia de cabeça e pescoço e artigos publicados entre 1980-2018, excluindo da pesquisa trabalhos experimentais em animais, artigos publicados na forma de nota técnica ou carta ao editor e artigos baseados em opinião de especialistas. Baseando-se nos critérios de pesquisa, foram selecionados 56 artigos. A radioterapia é eficaz e amplamente utilizada como terapia nas neoplasias malignas de cabeça e pescoço, entretanto produz efeitos colaterais, sendo a osteorradionecrose uma das mais graves. Na maioria dos casos, progride lentamente, tornando-se extensa e dolorosa, suas manifestações tardias compreendem infecção e fratura óssea patológica. Nas últimas décadas, várias opções profiláticas ou terapêuticas foram consideradas no manejo da osteorradionecrose, sendo as mais relatadas: medidas de suporte, antibioticoterapia/antibioticoprofilaxia, pentoxifilina e tocoferol, oxigênio hiperbárico e ressecção cirúrgica com enxerto ósseo. A adequação do meio bucal e cirurgias orais antes de iniciar a radioterapiaainda é o tratamento ideal para prevenir a osteorradionecrose. A antibioticoterapia e/ou antibioticoprofilaxia sistêmica, anti-sépticos locais, pentoxifilina e tocoferol e oxigênio hiperbárico são os tratamentos mais relatados na literatura e que buscam minimizar a incidência da osteorradionecrose após procedimentos cirúrgicos odontológicos em pacientes submetidos a tratamentos de radioterapia(AU)


The purpose of this paper was to review the literature and to emphasize the aspects related to the preventive and therapeutic management of osteorradionecrosis of the jaws. Methods: A nonsystematic, descriptive and qualitative bibliographic review was performed on the Scielo, Pubmed and Medline research platforms, using the descriptors, osteoradionecrosis/osteoradionecrose and/or radiotherapy/radioterapia and/or jaw/maxilares. The inclusion criteria were: articles published in English, Spanish or Portuguese, clinical research or reports of cases approaching of treatment with head and neck radiotherapy and articles published between 1980- 2018, excluding from the research experimental study on animals, articles published in the form of technical note or letter to the editor and articles based on expert opinion. Results: Based on the search criteria, 56 articles were selected. Radiotherapy is effective and widely used as a therapy for malignant head and neck neoplasias, however it produces side effects, being osteoradionecrosis the most severe one. In most cases, it progresses slowly, becoming extensive and painful; its late manifestations comprise infection and pathological bone fracture. In the last decades, several prophylactic or therapeutic options have been considered in the management of osteoradionecrosis, being reported: supportive measures, antibiotic therapy/prophylaxis, pentoxifylline, tocopherol, hyperbaric oxygen and surgical resection with bone graft. Conclusion: The suitability of the oral cavity and oral surgery before starting the radiation therapy is still an ideal treatment to prevent osteoradionecrosis. Antibiotic therapy/prophylaxis, local antiseptics, pentoxifylline, tocopherol and hyperbaric oxygen are the most commonly reported treatments in the literature and seek to minimize the incidence of osteoradionecrosis after dental surgical procedures in patients undergoing radiation therapy(AU)

ABSTRACT

Abstract It is necessary to preserve height and thickness of the alveolar bone to facilitate rehabilitation with osteointegratable implants or simply to maintain bone integrity after extraction. Biomaterials associated with resorbable or non-resorbable membranes, when placed in the region of the socket, may contribute to avoid this unwanted reabsorption. Objective The objective of this study was to evaluate the distance of the crest of alveolar ridge to the cementoenamel junction (CEJ) of the lower second molars and the bone density of the third molar socket filled with Gen-Tech®, 5 years after an exodontia using cone beam computed tomography (CBCT) to visualize the central region of the sockets, without overlapping of the buccal and lingual cortical bones. Material and Methods A total of 12 individuals from an initial group of 39 patients submitted to extraction of the unruptured lower third molars and grafting of an association of inorganic bovine bone matrix, organic bovine bone matrix, collagen and bone morphogenetic proteins (BMP) (Gen-Tech®) on one side and the contralateral sockets filled only by clot, returned to control after 5 years, and were submitted to CBCT. The distance from the crest of alveolar bone to the CEJ and the bone density (BD) were measured using the i-CAT Vision Software. Results The results showed that the distance from the crest of alveolar bone to the CEJ in the control group was similar to that observed before the exodontia; in the experimental group, this distance was smaller. Considering the BD measurement, a significantly higher density was observed in the experimental group (p<0.05). Conclusion Part of the biomaterial was not absorbed and allowed the stability of the evaluated parameters after 5 years, being able to be used as a bone substitute in the socket.

ABSTRACT

Transverse maxillary deficiency is characterized by posterior uni or bilateral crossbite, crowded and rotated teeth, as well as high palate. Its treatment in adult individuals is surgically assisted rapid palatal expansion. The aim of this study was to verify the occurrence of dimensional alterations in the mandibular condyles of patients with TMD submitted to surgically assisted maxillary expansion. Measurements of the mandibular condyles using the DISTANCE tool in cone beam computed tomography iCat software were performed. The values obtained were submitted to statistical analysis by the paired t-test and the results showed statistically significant dimensional reduction in the axial posterior-anterior lateral (-0.74mm), axial posterior-anterior lateral left (-0.90mm) and coronal medium right (-1.24mm) dimensions. The coronal inferior (1.13mm), coronal inferior left (1.78mm) and coronal superior-inferior right (0.76mm) measurements showed statistically significant dimensional increase. The results allowed us to conclude that dimensional alterations occurred in the mandibular condyles in individuals with maxillary transversal deficiency that underwent surgically assisted rapid palatal expansion (SAPE), which can be understood by remodeling, since they are characterized by dimensional increase or reduction, depending on the location where the measurement was performed (AU)

ABSTRACT

Introduction: Different rates of resorption are mediated by osteoclasts that may be affected by bisphosphonates during bone graft repair. Bisphosphonates are drugs that act as inhibitors of bone resorption. Objective:The aim of the present study was to evaluate the rate of resorption of skullcap grafts in rabbits with and without the use of alendronate sodium. Material and method: Thirty two New Zealand rabbits were divided into two groups (control group and alendronate group) and divided again into four periods (7, 14, 30 and 60 days). The control group did not receive alendronate, while animals of the experimental group received 4 mg of alendronate sodium weekly after the surgery. An 8 mm diameter bone block was removed from the parietal bone and fixed by screws to the contralateral parietal bone. During the periods of 7, 14, 30 and 60 days, the animals had undergone euthanasia and samples were removed for further analysis. Morphological and histomorphometric tests were used to compare graft thicknesses and to evaluate the newly formed bone at the interface between the graft and receptor site. The Wilcoxon and Mann-Whitney tests were used for statistical analyses. Result: All grafts healed and integrated uneventfully and no statistically significant differences in resorption rates or bone deposition were detected after the final incorporation of the graft in both groups. Conclusion: Alendronate Sodium did not decrease the bone graft resorption rates, but there was a tendency for better results in the control group regarding the resorption and neoformation in autogenous calvarial bone grafts in rabbits.


Introdução: Durante o reparo de enxertos ósseos, diferentes taxas de reabsorção são mediadas pelos osteoclastos e podem ser afetadas pelos bisfosfonatos, que são drogas que agem como inibidores da reabsorção óssea. Objetivo: Avaliar a taxa de reabsorção dos enxertos ósseos de calota craniana de coelhos, com e sem o uso alendronato de sódio. Material e método: Trinta e dois coelhos Nova Zelândia foram divididos igualmente em 2 grupos (grupo controle e grupo alendronato de sódio) e subdivididos em 4 períodos (7, 14, 30 e 60 dias). O grupo controle não recebeu alendronato, enquanto os animais do grupo experimental receberam 4 mg de alendronato de sódio por semana, em dose única, após a cirurgia. Um bloco de osso de diâmetro de 8 mm foi retirado o osso parietal e fixado com parafuso no osso parietal contralateral. Após cirurgia, nos períodos de 7, 14, 30 e 60 dias, os animais foram eutanasiados e as peças removidas para análise. Análises morfológica e histomorfométrica foram utilizados para comparar a espessura do enxerto e para avaliar a interface de osso recém formado entre o enxerto ósseo e o sítio receptor. Os testes de Wilcoxon e Mann-Whitney foram utilizados para as análises estatísticas. Resultado: Todos os enxertos repararam e integraram sem intercorrências; não foram detectadas diferenças estatisticamente significativas nas taxas de reabsorção ou deposição óssea, após a incorporação final do enxerto em ambos os grupos. Conclusão: Alendronato de sódio parece não diminuir a taxa de reabsorção, porém houve uma tendência de resultados melhores no grupo controle tanto na reabsorção quanto na neoformação óssea em enxertos ósseos autógenos de calota craniana de coelhos.

ABSTRACT

AbstractSurgically assisted rapid maxillary expansion (SARME) is the treatment of choice to adult patients even with severe transversal maxillary discrepancies. However, the adequate retention period to achieve the bone remodeling, thus assuring treatment stability, is controversial.Objective To evaluate the opening pattern and bone neoformation process at the midpalatal suture in patients submitted to surgically assisted (SARME) through cone beam computed tomography (CBCT).Material and Methods Fourteen patients were submitted to SARME through subtotal Le Fort I osteotomy. Both the opening pattern and the mean bone density at midpalatal suture area to evaluate bone formation were assessed pre- and post-operatively (15, 60 and 180 days) through CBCT.Results Type I opening pattern (from anterior to posterior nasal spine) occurred in 12 subjects while type II opening pattern (from anterior nasal spine to transverse palatine suture) occurred in 2 individuals. The 180-day postoperative mean (PO 180) of bone density value was 49.9% of the preoperative mean (Pre) value.Conclusions The opening pattern of midpalatal suture is more related to patients’ age (23.9 years in type I and 33.5 years in type II) and surgical technique. It was not possible to observe complete bone formation at midpalatal suture area at the ending of the retention period studied (180 days).

ABSTRACT

The retention mucous cyst of the maxillary sinus is a benign lesion that occurs in the interior of the maxillary sinus due ductal obstruction. In the majority of the cases it is asymptomatic, and discovered on routine radiographic examinations. However, in some cases, this cyst can become large and cause symptoms as paresthesia, sensitivity to palpation, chronic headache, nasal blockage, and dizziness. Conservative treatment is conduct in most cases. Symptomatic retention cysts are treated by enucleation or curettage. Objective and case report: This study aimed to report a clinical case of symptomatic mucous retention cyst accidentally discovered in a patient treated by surgically-assisted rapid maxillary expansion. Conclusion: The curettage of the cyst allowed for the regression of symptoms and at 12 months postoperatively the patient is free of symptoms and no signs of recurrence of lesion were noted.

ABSTRACT

Introduction: Torus palatinus is a specific name to identify exostoses developed in the hard palate along the median palatine suture. Despite of not being a pathological condition, its presence requires attention and knowledge regarding its management. Surgical removal of exostoses is indicated when the patient frequently traumatizes the area of palatine torus during mastication and speech or when it is necessary for the rehabilitation of the upper arcade with complete dentures. Objective: The aim of this article is to present three cases of Torus palatinus and to discuss the management of them. Case Report: In the first case, a 57-year-old Caucasian man sought oral rehabilitation of his edentulous maxilla but presented a hard nodules in the hard palate; in the second case, a 40-year-old Caucasian woman was referred for frequent trauma of palatal mucosa during mastication, aesthetic complaint, and discomfort caused by the trauma of her tongue in this area; and in the third case, a 45-year-old Caucasian woman presented with a lesion on the palate that caused difficulty swallowing. When the Torus palatinus was impairing the basic physiological functions of the patients, all cases were surgically treated, improving the patients' quality of life. Final Consideration: The dentist should be properly prepared to choose the best from among the existing surgical approaches for each individual lesion in order to improve the results and avoid possible complications. .


Introdução: Torus palatinus é um nome específico usado para identificar exostoses no palato duro ao longo da sutura palatina mediana. Apesar de não ser considerado uma condição patológica, sua presença requer atenção e conhecimento no que diz respeito ao seu tratamento. A remoção cirúrgica de exostoses é indicada quando o paciente traumatiza frequentemente a área do Torus palatinus durante a mastigação e a fala, ou quando for necessária a reabilitação da arcada dentária superior com próteses totais. Objetivo: O objetivo deste trabalho é apresentar três casos de Torus palatinus e discutir os seus respectivos tratamentos. Caso Clínico: O primeiro caso era de um homem leucoderma e com maxila edêntula que procurou reabilitação dentária, porém apresentou um nódulo no palato duro. O segundo caso era de uma mulher, leucoderma e de 40 anos que foi encaminhada devido ao trauma frequente na mucosa do palato durante a mastigação, insatisfação com a estética e desconforto causado pelo trauma na língua. O terceiro caso era de uma mulher de 45 anos de idade, leucoderma com uma lesão no palato e dificuldade pra engolir. Uma vez que o Torus palatinus estava prejudicando as funções fisiológicas básicas dos pacientes, todos os casos foram cirurgicamente tratados, melhorando a qualidade de vida dos mesmos. Consideração final: O dentista deve estar preparado para selecionar a técnica cirúrgica mais indicada para cada caso buscando o melhor resultado e evitando possíveis complicações. .

ABSTRACT

OBJECTIVE: To investigate whether there is any relationship between otological as well as vestibular symptoms, audiological findings and type of temporomandibular disorder (articular, muscular and mixed); and to check the distribution of the temporomandibular disorders (TMD) dysfunction degree in the research population. METHODS: A retrospective study involving 30 patients of both sexes, aged between 18 and 49 years old, diagnosed with TMD and dentofacial deformities, who were subject to clinical evaluation (muscle palpation, auscultation of temporomandibular joint during mandibular motion and measurement of jaw movement), audiological testing (pure tone audiometry and immittance testing) and two questionnaires, one on otological and vestibular symptoms and the other on TMD anamnesis. Based on both the anamnesis questionnaire and the clinical assessment, the subjects were divided according to the type and degree of TMD dysfunction (mild, moderate and severe), and compared regarding the occurrence of auditory signs and symptoms, vestibular symptoms and audiological findings according to TMD type. RESULTS: The anamnesis questionnaire demonstrated higher prevalence (83.33%) of severe TMD. Subjects with mixed TMD had more complaints about hypoacusis than those with muscular TMD (p < 0.05). The results showed no change in either audiological and immittance testing for all assessed individuals. CONCLUSION: Otological symptoms are present in subjects with TMD and dentofacial deformities, regardless of the classification of TMD (articular, muscular or mixed). Those with mixed TMD may have higher incidence of complaints about hypoacusis than subjects with muscular TMD. Further studies are needed to investigate the relationship between otological symptoms and the different types of TMD.


OBJETIVO: investigar se há relação entre os sintomas otológicos, vestibulares, achados audiológicos e o tipo de disfunção temporomandibular (articular, muscular e misto), e verificar a distribuição do grau de disfunção da DTM nessa população. MÉTODOS: estudo retrospectivo, envolvendo 30 pacientes com deformidades dentofaciais diagnosticados com DTM, de ambos os sexos, entre 18 e 49 anos de idade, submetidos a avaliação clínica (palpação muscular, ausculta da articulação temporomandibular durante os movimentos mandibulares e mensuração da movimentação da mandíbula), exame audiológico (audiometria tonal limiar e imitanciometria) e a dois questionários, sendo um sobre sintomas otológicos e vestibulares e outro anamnético da DTM. A partir do questionário anamnético e da avaliação clínica, os sujeitos foram divididos conforme o tipo e o grau da disfunção da DTM (leve, moderado e severo), e comparados quanto à ocorrência dos sinais e sintomas auditivos, vestibulares e achados audiológicos, de acordo com o tipo de DTM. RESULTADOS: houve maior prevalência (83,33%) de DTM severa de acordo com questionário anamnético. Sujeitos com DTM mista apresentaram mais queixas de hipoacusia do que aqueles com DTM muscular (p < 0,05). Os resultados evidenciaram ausência de alterações nos exames audiológico e imitanciométrico para todos os indivíduos avaliados. CONCLUSÃO: sintomas auditivos estão presentes nos sujeitos com DTM e deformidades dentofaciais, independentemente da classificação da DTM (articular, muscular ou mista), e aqueles com DTM mista podem apresentar maior ocorrência de queixa de hipoacusia do que sujeitos com DTM muscular. Estudos futuros são necessários para investigar a relação entre a sintomatologia auditiva e os diversos tipos de DTM.

ABSTRACT

Agenesia dentária é uma anomalia genética que caracteriza-se pela ausência total de um ou mais dentes. Ocorre em de 6% da população brasileira, geralmente no segundo pré-molar inferior e representa um desafio para a reabilitação, pois leva a alterações funcionais e estéticas. Nesse contexto, os implantes osseointegráveis ocupam lugar de destaque, dentre eles, os implantes de superfície SLActive®, que promovem aceleração no período de osseointegração, reduzindo esse tempo para 21 dias, além de melhor qualidade do osso neoformado ao redor dos implantes. Com altos índices de sucesso, mesmo quando submetidos a carga oclusal precoce ou imediata, tais implantes têm revolucionado a implantodontia moderna. O objetivo desse trabalho é relatar caso de agenesia dentária do segundo pré-molar inferior, reabilitado por meio de implante de superfície SLActive® e instalação da coroa protética definitiva na quinta semana pós-operatória.


Dental agenesis is a genetic abnormality characterized by total absence of one or more teeth. It affects about 6% of the population, affects preferably the second mandibular premolar and represents a challenge for rehabilitation because it leads to functional and esthetic problems. Currently, dental implants play a prominent role in rehabilitation, and the SLActive® implants stand out because they accelerate osseointegration, shorten it to 21 days, and ensure better quality of new bone around the implant. With high rates of success even when immediate or early loading is used, these implants have revolutionized modern Implantology. This report describes a case of dental agenesis of the second mandibular premolar treated using a SLActive® implant and a final prosthetic crown installed on the fifth postoperative week.

Introdução: a Ortodontia como uma especialidade odontológica tem mostrado para a sociedade a sua grande relevância e seu impacto na promoção da saúde da população. Enquanto ciência, os avanços para tratamento e reabilitação de pacientes são incontestáveis,desde situações mais simples às mais complexas, proporcionando saúde e bem-estar a um número cada vez maior de pessoas. Por outro lado, o grande número de profissionais tem gerado preocupações e inquietações à medida que tratamentos podem ser conduzidos deforma inadequada. Objetivo: neste artigo será abordada a importância do diagnóstico de patologias dos maxilares por meio da descrição de quatro situações clínicas, nas quais pacientes sob tratamento ortodôntico, portadores de lesões visíveis ao exame radiográfico panorâmico,tiveram o diagnóstico destas lesões negligenciado ou desconsiderado.Conclusão: a radiografia panorâmica constitui importante meio de diagnóstico de patologias assintomáticas dos maxilares, devendo ser criteriosamente avaliada antes do início da terapia ortodôntica.A parceria com outras especialidades da Odontologia é fortemente aconselhada na rotina do ortodontista.


Introduction: orthodontics as a dental specialty has shown its relevance to society and a great impact on the promotion of public health. The advances in the treatment and rehabilitation of orthodontic patients, from mild to severe cases, provide health and wellness to a growing number of people. On the other hand, the growing number of orthodontic professionals has raised concems,as treatments can be conducted improperly Objective: in this articlewe discuss the importance of diagnosis of pathological changes of the jaws through the description of four clinical situations in which patients under went orthodontic treatment. Lesions which were visible on panoramic radiographs were overlooked or disregarded for these patients. Conclusion: the panoramic radiograph is an important modality of diagnosis of asymptomatic pathological changes of the jaws. The panoramic image must be carefully evaluated before the beginning of orthodontic treatment. Collaboration with other specialties of dentistry is strongly recommended for the orthodontist.

ABSTRACT

O objetivo deste trabalho foi realizar análise clínica retrospectiva de implantes de corpo único, utilizados na reabilitação total de mandíbulas com carga imediata, verificando o índice de sobrevivência dos implantes e das próteses e a condição da mucosa ao redor das fixações. Além disso, foi realizada uma comparação entre duas técnicas para a instalação destes implantes. Para avaliação das próteses foi verificada a posição de acesso dos parafusos dos implantes mais distais, afrouxamento ou fratura de parafusos. Os implantes foram avaliados individualmente com o auxílio de uma sonda milimetrada. Os seguintes parâmetros clínicos foram observados: presença de placa; tendência a sangramento dos tecidos peri-implantares; supuração; presença de bolsa peri-implantar; evidência radiográfica de perda óssea. Um total de 111 implantes instalados foi avaliado. O tempo de função dos implantes variou de seis meses a cinco anos e a taxa de sobrevivência das fixações foi de 99,1%. Os resultados mostraram que a utilização do implante de corpo único na reabilitação total de mandíbulas, com carga imediata, mostrou ser uma alternativa viável de tratamento. A instalação pela técnica livre foi melhor para a reabilitação protética. Os implantes de corpo único utilizados no estudo apresentaram boa condição de saúde peri-implantar.


The purpose of this retrospective clinical study was to evaluate one-piece dental implants immediately loaded in the edentulous mandible by means of survival rate and peri-implant soft tissue health. Two placement techniques were evaluated. Prosthetic outcomes included evaluation of the most distal access screw hole, screw loosening and/or fracture. The implants were evaluated with the aid of a periodontal probe. Plaque build-up, bleeding on probing, pus, and peri-implant pocket, as well as radiographic evidence of bone loss was also addressed. Overall, 111 dental implants (6 months – 5 year in function) were evaluated. The implant survival rate was 99.1%. The results showed that the one-piece implant is a viable alternative for immediate loading protocols at the anterior mandibular region. The free placement technique was the best alternative for prosthetic reconstruction. The peri-implant soft tissue health was considered good when associated to the one-piece dental implants

ABSTRACT

Atualmente, a remoção dos terceiros molares inferiores retidos apresenta-se como um procedimento cirúrgico comum dentro dos consultórios odontológicos, sendo que a maioria é extraída profilaticamente. A indicação de remoção apresenta-se indefinida na literatura atual, uma vez que a manutenção dos mesmos relaciona-se comcomplicações patológicas ou traumáticas; entretanto, o procedimento cirúrgico propriamente dito não se apresenta livre de complicações, fato este que pode contraindicar a intervenção cirúrgica profilática. Este trabalho objetiva, por meio de revisão da literatura, abordar informações sobre a remoção profilática dos terceiros molares inferiores retidos e assintomáticos, visando inquirir sobre a correlação entre os mesmos com as fraturas mandibulares e as possíveis alterações foliculares patológicas.


Currently, the removal of impacted mandibular third molars is presented as a common surgical procedure in the dental offices, and most of them are prophylactically extracted. The indication of its removal presents unclear inthe literature, since the maintenance of these relates to pathological or traumatic complications and the surgical procedure does not present some complications, this fact may contraindicate the surgical prophylaxis intervention. This paper aims, through a literature review, address information on the prophylactic removal of asymptomatic andimpacted third molars, in order to inquire about the correlation between them with mandibular fractures and the possible pathological folliclular changes.
