Odontogenic maxillary sinusitis associated with foreign body displacement after tooth extraction: report of an unusual case / Sinusite maxilar odontogênica por corpo estranho após extração dentária: relato de um caso incomum

Background: Odontogenic maxillary sinusitis caused by a foreign body presents diagnostic and therapeutic challenges due to its infrequent occurrence and unique characteristics compared to sinusitis originating from other sources. CaseReport:Illustrating such fact, this report presents the clinical case of a 37-year-old woman referred complaining of pain in the same region where she had extracted her upper right first molar five days before. The intraoral examination revealed the presence of an orifice in the region, suggesting oroantral communication. Imaging exams revealed opacification of the right maxillary sinus and the unexpected presence of a highly radiodense object. With the diagnosis of maxillary sinusitis due to a foreign body established, the surgical approach initially consisted of administering preoperative medication, preceded by access to the maxillary antrum using the Caldwell-Luc technique. The object was found and removed, consisting of a surgical drill. At follow-up there was complete absence of symptoms and complete closure of communication. Conclusion: Cases of odontogenic maxillary sinusitis caused by drill detachment after tooth extraction are fairly uncommon. A thorough clinical evaluation proved to be essential and the Caldwell-Luc access was effective, safe and with good postoperative results, even with the absence of standardized diagnostic and management methods(AU)

Contexto: A sinusite maxilar odontogênica causada por corpo estranho apresenta desafios diagnósticos e terapêuticos devido à sua ocorrência infrequente e características únicas em comparação com sinusites originadas de outras fontes. Relato do Caso: Ilustrando tal fato, este relato apresenta o caso clínico de uma mulher de 37 anos de idade encaminhada com queixa de dor em mesma região que havia extraído o primeiro molar superior direito cinco dias antes. Ao exame intraoral verificou-se a presença de um orifício na região, sugerindo comunicação oroantral. Os exames de imagem revelaram opacificação do SM direito e a inesperada presença de um objeto altamente radiodenso. Com o diagnóstico de sinusite maxilar por corpo estranho estabelecido, a abordagem cirúrgica consistiu inicialmente na administração de medicação pré-operatória, precedida pelo acesso ao antro maxilar através da técnica de Caldwell-Luc. O objeto foi encontrado e removido, consistindo em uma broca cirúrgica. Ao acompanhamento houve ausência completa dos sintomas e total fechamento da comunicação. Conclusão: Casos de sinusite maxilar odontogênica causada por descolamento da broca após extração dentária são bastante incomuns. Uma avaliação clínica minuciosa mostrou-se primordial e o acesso de Caldwell-Luc eficaz, seguro e com bons resultados pós-operatórios, mesmo com as ausências de métodos de diagnóstico e manejo padronizados.(AU)

Chronic Bi-Maxillary Osteomyelitis Caused by Actinomycetes in a Patient with Severe COVID-19 / Osteomyelitis bi-maxilar crónica causada por Actinomycetes en un paciente con COVID-19 severo

Abstract Osteomyelitis is defined as the inflammation of the either medullary, cortical, or cancellous bone, including nerves and blood vessels, causing necrosis and bone sequestrum formation; this condition has become a rare pathology, and odontogenic infections are considered the most frequent causal factor. This case shows a patient with bi-maxillary osteomyelitis caused by Actinomyces spp, which was worsened for severe COVID-19 infection. Patient was submitted at surgery as, amplified total bilateral maxillectomy through the surgical technique Weber-Fergusson, and prolonged use of combination of antibiotics, achieved a good recovery. Two years later follow- up, the patient no show imaging or clinical evidence of the infection of osteomyelitis. The present case shows an interesting relationship between a rare infection and its association with COVID-19.

Resumen La osteomielitis se define como la inflamación del hueso medular, cortical o esponjoso, incluyendo nervios y vasos sanguíneos, causando necrosis y formación de secuestro óseo; esta condición es una patología rara, y las infecciones odontogénicas son consideradas como el factor causal más frecuente. En este caso, se muestra un paciente con osteomielitis bi-maxilar causada por Actinomyces spp, la cual empeoró por la infección de COVID-19 severo. El paciente fue sometido a una cirugía, maxilectomía bilateral total amplificada, a través de la técnica quirúrgica de Weber- Fergusson, y el uso prolongado de una combinación de antibióticos, logrando una buena recuperación. A los 2 años de seguimiento, el paciente no mostró evidencia clínica o imagenológica de la infección de osteomielitis. El presente caso muestra una interesante relación entre una infección rara y su asociación con COVID-19.

Manejo odontológico del paciente en tratamiento de anticoagulante oral sometido a cirugía oral: una revisión narrativa / Stomatological management of anticoagulated patients undergoing oral surgery: a narrative review

Resumen Los pacientes que se encuentran bajo tratamiento de anticoagulantes orales, presentan alteraciones en distintas etapas de la hemostasia, lo que conlleva a tener implicancias y consideraciones médico/quirúrgicas durante su atención. En la actualidad, no existe un consenso en relación con el manejo odontológico de estos pacientes que serán sometidos a procedimientos quirúrgicos, llevando a protocolos clínicos que siguen diversas posturas, como la de disminuir la ingesta farmacológica del anticoagulante, sustituir con heparina y la de mantener el tratamiento bajo control. Objetivo Establecer el manejo estomatológico del paciente que se encuentra en tratamiento de anticoagulante oral mediante una revisión profunda de la literatura Materiales y método Se realizó una búsqueda de revisión bibliográfica manualmente de artículos indexados a las bases de datos de PUBMED y EBSCO que correspondiesen a las palabras "cirugía bucal", "anticoagulantes", "atención dental" y "hemorragia oral". En cuanto a los criterios de inclusión, se consideraron revisiones bibliográficas, estudios observacionales, ensayos clínicos, guías, revisiones sistemáticas y metaanálisis publicados entre noviembre de 2005 y 2022, en idiomas inglés o español. Conclusiones Existen múltiples protocolos para la atención del paciente anticoagulado que será sometido bajo procedimiento de cirugía oral menor. Es importante considerar el anticoagulante utilizado, motivo, control de este, el procedimiento a realizar en el paciente y medidas hemostáticas tanto intra como postoperatorias por realizar, tras analizar lo anterior, se advierte que disminuir la ingesta del fármaco para realizar el procedimiento, puede ser más perjudicial al paciente como al clínico, por lo tanto se sugiere mantener el tratamiento antitrombótico y realizar un correcto manejo médico/quirúrgico.

Abstract Patients undertaking oral anticoagulant treatment may experience alterations in different stages of hemostasis, which lead to medical/surgical implications and considerations during their care. Currently, there is no consensus regarding the dental management of these patients, as they go through surgical procedures. This leads to clinical protocols that follow numerous approaches, such as reducing the pharmacological intake of the anticoagulant, replacing it with heparin, and maintaining the controlled treatment. Objective: To establish the stomatological management of the patient undergoing oral anticoagulant treatment through an in depth review of the literature. Materials and Method: A manual bibliographic review search of articles indexed to the PUBMED and EBSCO databases corresponding to the words "oral surgery", "oral bleeding", "anticoagulants" and "dental management" was performed. Regarding the inclusion criteria: bibliographic reviews, observational studies, clinical trials, guidelines, systematic reviews, and meta-analyses published between November 2005 and 2022, in English or Spanish, were considered. Conclusion: There are multiple protocols for the care of the anticoagulated patient who will undergo a minor oral surgery procedure. It is important to reflect on the anticoagulant used, the reason for it, its supervision, the surgical procedure that will be undertaken by the patient, and both intraoperative and postoperative hemostatic measures to be implemented. After analyzing the above, it is noted that reducing the intake of the drug to perform the surgical procedure may be harmful to the patient and to the clinician, therefore it is suggested to maintain the antithrombotic treatment and carry out a correct medical/surgical management.

The result of post-extraction complications reached 5.4 % (n = 8), where the most frequent complication was alveolitis. Post-extraction complications are significantly related to the level of mild difficulty (p 0,05).

Exodontia de primeiro molar superior permanente em criança: relato de caso / Clínico maxillary first permanent molar extraction in a child: case report

Entre as perdas precoces de um elemento dental ocorre em grande frequência a do primeiro molar permanente, que normalmente tem o seu irrompimento por volta dos 6 anos de idade, e são propensos a serem acometidos por lesões cariosas que se não cuidadas precocemente pode-se levar a perda do elemento dental. Há também outros agentes que ocasionam a perda do elemento como o trauma de baixa intensidade, tais como, os cálculos dentários, os hábitos bucais deletérios e principalmente a falta de motivação de higiene oral. Diante disto, este trabalho visa a apresentação de um caso clínico de um paciente de 9 anos de idade, sem alterações sistêmicas, com grande destruição coronária no dente 26. Os exames de imagens foram colaboradores para diagnóstico e definição da extração. Foi realizada a exodontia em campo aberto. O paciente foi instruído quanto à higiene bucal e futuramente encaminhado para um tratamento ortodôntico. Conclui-se que o Cirurgião Dentista tem papel fundamental no diagnóstico e tratamento dessas alterações dentais, enfatizando a importância do tratamento restaurador de lesões cariosas precocemente, remoção de qualquer agente irritante de baixa intensidade e na motivação da higiene bucal(AU)

Among the early loss of a dental element, the loss of the first permanent molar occurs very frequently, which usually has its eruption around the age of 6 years, and they are prone to be affected by carious lesions that, if not treated early, can if it leads to loss of the dental element. There are also other agents that cause the loss of the element, such as low-intensity trauma, such as dental calculi, deleterious oral habits and especially the lack of motivation for oral hygiene. Therefore, this work aims to present a clinical case of a 9-year-old patient, without systemic alterations, with great coronary destruction in tooth 26. The imaging exams collaborated for the diagnosis and definition of the extraction. The extraction was performed in an open field. The patient was instructed about oral hygiene and later referred for orthodontic treatment. It is concluded that the Dental Surgeon has a fundamental role in the diagnosis and treatment of these dental alterations, emphasizing the importance of an early restorative treatment of carious lesions, removal of any low-intensity irritant and in the motivation of oral hygiene(AU)

Cambios Hemodinámicos Asociados a Exodoncias de Terceros Molares Inferiores con el Uso de Articaína 4 % y/o Lidocaína 2 %: Una revisión sistemática / Hemodynamic Changes Associated with Lower Third Molar Extractions with the Use of Articaine 4 % and/or Lidocaine 2 %: A systematic Review

La exodoncia de los terceros molares inferiores es uno de los procedimientos clínicos más comunes en el cual el control del dolor mediante el bloqueo anestésico del nervio alveolar inferior, bucal y lingual resulta ser fundament al y la manera más común de hacerlo es mediante la infiltración de soluciones de anestesia local. Entre ellos la lidocaína y articaína son algunos de los más comunes y pueden estar asociado a vasoconstrictores como la epinefrina que puede provocar aumento de la presión arterial y frecuencia cardíaca razón por la cual se hace necesario la monitorización de cambios hemodinámicos durante la cirugía. Describir los cambios hemodinámicos asociados al uso de lidocaína al 2 % y/ o articaína al 4 % en la presión sistólica y diastólica, frecuencia cardiaca y saturación parcial de oxígeno en relación a distintos tiempos operatorios. Se realizó una revisión sistemática en las bases de datos de PubMed, SCOPUS, Web of Science y Sciencedirect. Se analizaron 7 ensayos clínicos controlados en los que utilizaron articaína al 4 % y/o lidocaína al 2 % con epinefrina al 1:100,000 y/o 1:200,000 en volúmenes de 1,8 a 5,4 mL, en los cuales evaluaron la presión sistólica y diastólica, frecuencia cardiaca y saturación parcial de oxígeno en distintos tiempos de la cirugía. Si bien hubo cambios en PAS, PAD, FC y SPO2, todas se mantuvieron dentro de rangos normales bajo el uso de articaína al 4 % y lidocaína al 2 % con epinefrina 1:100,000 y/o 1:200,000 a volúmenes de 1,8 a 5,4mL medidas a distintos tiempos operatorios.

The extraction of lower third molars is one of the most common clinical procedures in which pain control through anesthetic blockade of the lower alveolar, buccal and lingual nerves turns out to be essential and the most common way to do it is through the infiltration of solutions of local anesthesia. Among them, lidocaine and articaine are some of the most common and may be associated with vasoconstrictors such as epinephrine, which can cause an increase in blood pressure and heart rate, which is why it is necessary to monitor hemodynamic changes during surgery. To describe the hemodynamic changes associated with the use of 2 % lidocaine and/or 4 % articaine in systolic and diastolic pressure, heart rate and partial oxygen saturation in relation to different operative times. A systematic review was carried out in the PubMed, SCOPUS, Web of Science and Sciencedirect databases. Seven controlled clinical trials were analyzed in which 4 % articaine and/or 2 % lidocaine were used with epinephrine at 1:100,000 and/or 1:200,000 in volumes of 1,8 to 5,4 mL, in which systolic pressure was evaluated. and diastolic, heart rate and partial oxygen saturation at different times of surgery. Although there were changes in SBP, DBP, HR and SPO2, all remained within normal ranges under the use of 4 % articaine and 2 % lidocaine with epinephrine 1:100,000 and/or 1:200,000 at volumes of 1,8 to 5 .4mL measured at different operative times.

Extenso quiste odontogénico radicular mandibular / Extensive mandibular radicular odontogenic cyst

Los quistes radiculares constituyen los quistes odontogénicos más comunes de la cavidad bucal. El objetivo de esta investigación es caracterizar un paciente con quiste odontogénico radicular mandibular. Se presenta un individuo masculino de 86 años, que fue atendido en el Servicio de Cirugía Maxilofacial del Hospital Provincial General Universitario «Mártires del 9 de abril», de Sagua la Grande, durante los años 2017-2018. Inicialmente, se le realizó el estudio clínico correspondiente (interrogatorio y examen físico), y se observó una evidente tumefacción y abombamiento cortical en relación a dientes residuales permanentes mandibulares; se asoció radiográficamente a una imagen radiolúcida ovoide extensa, que justificó la realización de biopsias incisionales en primer orden. Se siguió una conducta quirúrgica, con resección total de la lesión mediante enucleación, y se confirmó el diagnóstico de quiste odontogénico radicular mandibular a través del estudio histopatológico.

Radicular cysts are the most common odontogenic cysts in the oral cavity. The objective of this investigation is to characterize a patient with a mandibular radicular odontogenic cyst. We present an 86-year-old male individual who was treated in the maxillofacial surgery service at "Mártires del 9 de Abril" Provincial General University Hospital in Sagua la Grande from 2017 to 2018. Initially, a corresponding clinical study was performed (interrogation and physical examination), and an evident swelling and cortical bulging was observed in relation to mandibular permanent residual teeth; it was radiographically associated with an extensive ovoid radiolucent image, which justified the performance of first-order incisional biopsies. A surgical procedure was followed, with total resection of the lesion by means of enucleation, and the diagnosis of mandibular radicular odontogenic cyst was confirmed through the histopathological study.

Lesiones cervicofaciales tumorales y pseudotumorales pediátricas en Villa Clara. Años 2010-2019 / Pediatric tumoral and pseudotumoral cervicofacial lesions in Villa Clara from 2010 to 2019

Caracterizar las lesiones cervicofaciales tumorales y pseudotumorales en niños en Villa Clara es una necesidad creciente por las alteraciones físicas, estéticas y psicológicas que pueden ocasionar. Se realizó un estudio transversal y descriptivo en el Servicio de Cirugía Maxilofacial Pediátrico de esta provincia, en el período 2010-2019. La población estuvo constituida por 101 niños con estudio histológico concluyente de lesión tumoral benigna, maligna o pseudotumoral de la región cervicofacial. Se concluyó que los tumores y pseudotumores en la región cervicofacial no tuvieron relación con la edad, género, ni color de la piel, en los niños estudiados. En esta serie predominaron los tumores benignos. El tumor maligno de mayor prevalencia fue el Linfoma de Burkitt. Existió alta correlación entre los diagnósticos clínico e histológico.

Characterizing tumoral and pseudotumoral cervicofacial lesions in children in Villa Clara is a growing need due to the physical, aesthetic and psychological alterations that they can cause. A cross-sectional and descriptive study was carried out in the pediatric maxillofacial surgery service of this province from 2010 to 2019. The population consisted of 101 children with conclusive histological study of benign and malignant tumoral or pseudotumoral lesions of the cervicofacial region. We concluded that tumors and pseudotumors in the cervicofacial region were not related to age, gender or skin color in the studied children. In this series, benign tumors predominated. The most prevalent malignant tumor was Burkitt's lymphoma. There was a high correlation between clinical and histological diagnoses.

Manejo das fraturas mandibulares associadas à exodontia de 3º molar inferior / Management of mandibular fractures associated with lower third molar extraction

A remoção cirúrgica dos terceiros molares é um procedimento comumente realizado por cirurgiões bucomaxilos, e acidentes e complicações podem estar relacionados a esse procedimento. A fratura mandibular é um acidente incomum, mas que apresenta grande potencial de gerar morbidade aos pacientes. Diante disso, evidencia-se a importância de uma abordagem precoce após o trauma, bem como o acompanhamento posterior e a determinação correta do tratamento. Nesse sentido, este estudo objetiva investigar na literatura os protocolos existentes de tratamentos de fraturas mandibulares transoperatórias associadas à exodontia de terceiros molares inferiores. Para isso, foi realizada uma revisão de literatura sistemática, de caráter exploratório e descritivo, na base de dados Pubmed através dos descritores mandibular fracture, extraction e treatment. As buscas foram realizadas com restrição de tempo de 2016 a 2021. Dos 18 artigos compatíveis à proposta, 6 artigos passaram pelos critérios de inclusão e exclusão. Desses, a análise da maioria dos autores é clara em se referir às exodontias de terceiros molares como fator para fraturas mandibulares e mencionar qual protocolo de atendimento seguir, caso aconteça a fratura. Conclui-se que a redução fechada ou aberta são possibilidades de abordagem, entretanto existe uma preferência, pela redução aberta por acesso extraoral ou intrabucal com fixação interna rígida, visto que, ela elimina o período de bloqueio maxilomandibular, facilitando o retorno à função.

Surgical removal of third molars is a common procedure performed by bucomaxilos surgeons, and accidents and complications can be related to this procedure. Mandibular fracture is an uncommon accident, but it has great potential to generate morbidity in patients. Because of this, the importance of an early approach after trauma is evident, as well as the subsequent follow-up and correct determination of treatment. In this sense, this objective is to investigate in the literature the existing protocols for the treatment of transverse mandibular fractures associated with the extraction of lower third molars. To this end, a systematic exploratory and descriptive literature review were conducted in the Pubmed database using the descriptors mandibular fracture, extraction and treatment. The searches were performed with a time restriction from 2016 to 2021. Of the 18 articles compatible with the proposal, 6 articles passed the inclusion and exclusion criteria. Of these, the analysis of most authors is clear in referring to third molar extractions as a factor for mandibular fractures and mentioning which treatment protocol to follow if a fracture occurs. It is concluded that closed or open reduction are possible approaches, however there is a preference for open reduction by extraoral or intraoral access with rigid internal fixation, since it eliminates the period of maxillomandibular block, facilitating the return to function.

Manejo de crisis hipertensiva en cirugía maxilofacial. Reporte de caso clínico / Hypertensive crisis management in maxillofacial surgery. Clinical case report

Introducción: un aumento marcado de la tensión arterial puede llevar a una crisis hipertensiva, que consiste en una elevación considerable de la tensión arterial (>180 mmHg en sístole y >120 mmHg en diástole). De no ser tratada, puede llevar a la pérdida progresiva de la conciencia, así como provocar daños irreversibles a algún órgano blanco, por ejemplo, el hígado, el riñón o el cerebro. Se puede clasifcar en urgencia o emergencia hipertensiva. Así, una urgencia hipertensiva se presenta cuando el paciente cuenta con cifras elevadas en la tensión arterial sin provocar daño a un órgano blanco y, en contraparte, una emergencia hipertensiva cumple con las cifras que se mencionaron, pero incluye daño a un órgano blanco. Objetivo: presentar un caso clínico, en el cual, durante la extracción quirúrgica de una aguja fracturada, en el período transoperatorio, el paciente sufre síncope vasovagal, con un aumento marcado de la tensión arterial (179/119 mmHg). Conclusión: este fue un diagnóstico intraoperatorio de crisis hipertensiva y la paciente recibió un tratamiento médico temprano por parte del servicio de urgencias médicas, lo cual resultó en una evolución trans y postoperatoria adecuada.

A marked increase in blood pressure can lead to a hypertensive crisis, it can be classifed as an urgency or hypertensive emergency, which consists of a considerable increase in blood pressure (> 180 mmHg in systole and> 120 mmHg in diastole) and that, not being treated can lead to progressive loss of consciousness, as well as cause irreversible damage to the liver, kidney or brain. The objective of this article is to present a clinical case that during the surgical extraction of a fractured needle, in the intraoperative period the patient sufers vasovagal syncope, with a marked increase in blood pressure (179/119 mmHg), intraoperative diagnosis of crisis hypertensive, receiving early medical treatment from the emergency medical service, resulting in an adequate trans and postoperative evolution.

Evaluating the efficacy of Etoricoxib in reducing post-operative pain associated with minor oral surgery. A randomized clinical trial / Avaliação da eficácia do Etoricoxibe na redução da dor pós-operatória associada à cirurgia oral menor: ensaio clínico randomizado

Etoricoxib, a new cyclooxygenase-2-selective inhibitor has demonstrated a rapid onset analgesic effect for relieving acute pain especially when prescribed as a pre-emptive medication. On these bases, this study may provide useful information and guidance for clinicians working in the field of oral surgery, as regards handling odontogenic pain and postoperative pain precisely with cyclooxygenase-2 inhibitors. Objective: the study aimed to measure the quantifiable efficacy of Etoricoxib in reducing post-extraction pain in subjects undergoing minor oral surgical intervention as compared to Naproxen (a traditional NSAID) which is commonly used to control postoperative pain. Material and Methods: a 120 mg film-coated tablet of Etoricoxib was given to each of the twenty patients representing the study group, and a 500 mg tablet of Naproxen was given to each of the other twenty subjects representing the positive control group. According to manufacturer instructions, the tablets were given to the subjects 30 minutes pre-operatively (before dental extraction). Post-operative pain was assessed for each subject using eleven points from zero to ten, visual analog scale. Results: showed no statistically significant difference between Etoricoxib and Naproxen in decreasing post-extraction odontogenic pain, suggesting that Etoricoxib is as efficient as Naproxen in the control of discomfort with dental origin taking into consideration the patient's status when prescribing the medication. Conclusion: this study suggests that Etoricoxib can be handled as a pre-emptive medication to reduce post-operative pain for subjects seeking traditional or surgical extraction of any of their teeth (AU)

O Etoricoxibe, um novo inibidor seletivo da ciclooxigenase-2, demonstrou um efeito analgésico de início rápido para aliviar a dor aguda, especialmente quando prescrito como medicação preventiva. Com base nesses fundamentos, este estudo pode fornecer informações úteis e orientação para clínicos que trabalham no campo da cirurgia oral, no que diz respeito ao manejo da dor odontogênica e da dor pós-operatória de forma precisa com inibidores da ciclooxigenase-2. Objetivo: o estudo teve como objetivo medir a eficácia quantificável do Etoricoxibe na redução da dor pós-extração em indivíduos submetidos a intervenção cirúrgica oral menor, comparado ao Naproxeno (AINE tradicional) que é comumente usado para controlar a dor pós-operatória. Material e Métodos: um comprimido revestido com um filme de 120 mg de Etoricoxibe foi administrado a cada um dos 20 pacientes representando o grupo de estudo, e um comprimido de 500 mg de Naproxeno foi administrado a cada um dos outros vinte sujeitos representando o grupo de controle positivo. De acordo com as instruções do fabricante, os comprimidos foram administrados aos indivíduos 30 minutos antes da cirurgia (antes da extração dentária). A dor pós-operatória foi avaliada para cada sujeito usando uma escala analógica visual de onze pontos, de zero a dez. Resultados: não mostraram diferença estatisticamente significativa entre o Etoricoxibe e o Naproxeno na diminuição da dor odontogênica pós-extração, sugerindo que o Etoricoxibe é tão eficiente quanto o Naproxeno no controle do desconforto de origem dentária, levando em consideração o estado do paciente ao prescrever a medicação. Conclusão: este estudo sugere que o Etoricoxibe pode ser administrado como medicação preventiva para reduzir a dor pós-operatória em indivíduos que buscam extração dentária tradicional ou cirúrgica de qualquer um de seus dentes.

Municipalities with higher development rates provided greater access to oral health services and lower proportions of tooth extractions per inhabitant.

Calcifying odontogenic cyst with AOT-like features: a case report and literature review / Cisto odontogênico calcificante com características adenomatóides: relato de caso e revisão de literatura

Odontogenic lesions are a heterogeneous group of diseases that presents differences in their biological behavior and the occurrence of variable inductive interactions. Calcifying odontogenic cyst (COC), or Gorlin's cyst, is a well-recognized example of these lesions. We describe a case of COC with AOT-like areas and highlights its morphological diversity. A 60-year-old pheoderma man presented with a large swelling in the anterior buccal region of the mandible. Panoramic radiography revealed a well-defined, unilocular, radiolucent lesion associated with important root resorption. Complete enucleation of the lesion was performed and the histopathological findings met the criteria for the diagnosis of COC, although the cyst exhibited unusual AOT-like features. The patient has been recurrence free for 6 months after surgery. COCs with AOT-like features are rare, and reflect the multipotentiality and complexity of the inductive effects of the odontogenic epithelium with the ectomesenchyme. Enucleation seems to be the most indicated treatment, similar to classical COC (AU)

As lesões odontogênicas são um grupo heterogêneo de patologias que apresentam diferenças no seu comportamento biológico, e ocorrência de interações indutivas variáveis. O cisto odontogênico calcificante (COC), ou cisto de Gorlin, é um exemplo bem conhecido destas lesões. Descrevemos um caso de COC com áreas adenomatóides e destacamos a sua diversidade morfológica. Paciente do sexo masculino, 60 anos de idade, apresentou um aumento de volume na região anterior da mandíbula. A radiografia panorâmica revelou uma lesão bem definida, unilocular e radiolúcida associada a uma reabsorção radicular importante. A enucleação completa da lesão foi realizada e os achados histopatológicos preencheram os critérios para o diagnóstico de COC, embora o cisto exibisse características adenomatóides pouco usuais. O paciente permanece livre de recidivas durante 6 meses após a cirurgia. Os COCs com características adenomatóides são raros, e refletem a multipotencialidade e complexidade dos efeitos indutivos do epitélio odontogênico com o ectomesênquima. A enucleação parece ser o tratamento mais indicado, semelhante ao COC clássico. (AU)

Efficacy of antibiotic prophylaxis on third molar extraction / Eficácia da profilaxia antibiótica na extração de terceiros molares

Introduction: Third molar extraction surgery is a common dental procedure, often challenging with increased post-operative complications. The need for antibiotic prophylaxis in these cases remains debated. Objective: The aim of this study was to evaluate the effect of antibiotic prophylaxis on the postoperative clinical course of third molar extraction surgeries. Material and method: Sixty-three patients were randomly allocated into two groups after extraction of the four third molars. ATB group (N = 33) the patients received 1g of amoxicillin one hour before the surgical procedure, CTR group (N = 30) the patients did not receive antibiotic prophylaxis. Clinical analyses were performed at 3, 7, 14, and 30 days after the surgical procedure. These analyses consisted of assessing oedema, variation in mouth opening, and soft tissue healing. Furthermore, patient-centered analyses were also carried out through the application of the visual analogue scale (VAS) to assess pain, inflammation, bleeding, difficulty opening the mouth, and chewing. Result: No influence of antibiotic prophylaxis was observed on the evolution of clinical parameters of healing, oedema, and mouth opening. Patients did not notice differences regarding their comfort during the postoperative period. Conclusion: The incidence of complications observed in the present study was low and was not related to infectious processes. The use of prophylactic antibiotic therapy has no beneficial effects on the postoperative clinical course in third molar extraction.

Introdução: Exodontia de terceiro molar é um procedimento odontológico comum, frequentemente desafiador, com complicações pós-operatórias aumentadas. A necessidade de profilaxia com antibióticos nesses casos ainda é motivo de debate. Objetivo: O objetivo deste estudo foi avaliar o efeito da profilaxia com antibióticos no curso clínico pós-operatório das cirurgias de extração do terceiro molar. Material e método: Sessenta e três pacientes foram randomicamente alocados em dois grupos posteriormente a cirurgia de exodontia dos quatro terceiros molares. Grupo ATB (N = 33) utilizou 1g de amoxicilina uma hora antes do procedimento cirúrgico e grupo CTR (N = 30) sem profilaxia antibiótica. Os dentes foram classificados de acordo com Pell & Gregory e Winter. Análises clínicas foram realizadas nos períodos de 3, 7, 14 e 30 dias após o procedimento cirúrgico. As análises consistiram na avaliação do edema, variação de abertura de boca e a cicatrização dos tecidos moles. Também foram executadas análises centradas nos pacientes por meio da aplicação da escala visual analógica (VAS) para avaliação de dor, inflamação, sangramento, dificuldade de abertura bucal e de mastigação. Resultado: Não houve diferenças entre os grupos em relação ao posicionamento dos dentes. Não foi observada influência da profilaxia antibiótica nos parâmetros clínicos de cicatrização, edema e abertura de boca. Os pacientes não notaram diferenças em relação ao seu conforto no pós-operatório. Conclusão: A incidência de complicações foi baixa e não foi relacionada a processos infecciosos. O uso de antibioticoterapia profilática não apresentou efeitos benéficos para o curso clínico pós-operatório em exodontia de terceiros molares.

Microbial evaluation of implant surface - a clinical study comparing submerged, non-submerged and immediately loaded implants

Aim: The aim of the present study was to evaluate the microbial contamination in internal and external walls of cone morse implant walls. Methods: Eleven patients with edentulous mandibular posterior area were selected to received dental implants, divided into groups: submerged (S), non-submerged (NS), and immediately loaded (IL). Microbiological evaluations (microorganisms' number, aerobic and anaerobic colony forming units (CFU) number and microorganisms' qualification) were divided into internal and external collection of the implant walls, at different stages: T0 (surgical procedure), T2 (suture removal), T4 (reopening S group), T6 (suture removal S group), and T8 (abutment placement in S and NS). All data were submitted to statistical analyses, with confidence level of 0.05. Results: There was difference in number of microorganisms observed over time within the same group (p < 0.05). A difference was observed in CFU when evaluated within the same group over time (p < 0.05), except for the IL group. In internal collection, a predominance of non-formation of microorganisms was observed at T0 in all groups, while formation of Gram-positive Diplococci and Gram-positive Bacilli was observed at T8 (p>0.05). In external collection, an increase in number of microorganisms was observed at T0. Conclusion: There was no difference in microbial contamination among the evaluated groups. The microorganism's colonization changed over time

The challenges of reconstruction and rehabilitation of atrophic jaw with an autogenous graft from skull cap ­ a case report / Os desafios da reconstrução e reabilitação de mandíbula atrófica com enxerto autógeno de calota craniana ­ relato de caso

Introduction: One of the challenges of maxillofacial surgery is the rehabilitation of patients with severe bone loss, using implant-supported prostheses. This challenge is based on the small remaining bone structure, and on the need to reconstruct the structure for the rehabilitation with autogenous or exogenous grafts. Case report: We report the case of a patient with severe maxillary atrophy, where a skullcap graft was performed associated with implant placement and prosthetic completion 14 months after the start of treatment. Final considerations: We demonstrate clinical safety for the use of extraoral grafts without complications, representing a good alternative treatment for this group of patients.

Introdução: um dos desafios da cirurgia bucomaxilofacial é a reabilitação de pacientes com perda óssea severa, utilizando próteses implantossuportadas. Este desafio baseia-se na pequena estrutura óssea remanescente e na necessidade de reconstrução da estrutura para a reabilitação com enxertos autógenos ou exógenos. Relato de caso: Relatamos o caso de um paciente com atrofia maxilar grave, onde foi realizado enxerto de calota craniana associado à instalação de implante, com finalização protética 14 meses após o início do tratamento. Consideracoes finais: Demonstramos segurança clínica para o uso de enxertos extrabucais sem complicações, representando uma boa alternativa de tratamento para este grupo de pacientes.
