Abordagens cirúrgicas para cisto dentígero: revisão de literatura / Surgical approaches for dentigerous cyst: literature review

O objetivo desta revisão integrativa foi elaborar uma avaliação qualitativa da literatura existente sobre as modalidades de tratamento utilizadas para cistos dentígeros em pacientes pediátricos. O presente estudo trata-se de uma revisão integrativa da literatura na qual utilizou-se as bases de dados PubMed, BVS (Biblioteca Virtual em Saúde), LILACS, e SciELO. Como critérios de inclusão estavam os artigos publicados na íntegra, relatos de caso clínico, revisões sistemáticas e de meta-análise publicados nos últimos 10 anos, disponível nos idiomas português ou inglês, que abordassem a temática. Os critérios de exclusão foram: resumos, anais, editoriais, cartas ao editor, reflexão, duplicidade, artigos com detalhamento incompleto. O cisto dentígero é o tipo mais comum dos cistos odontogênicos de desenvolvimento e o segundo mais frequente entre todos que ocorrem nos maxilares, representando cerca de 20% de todos os cistos revestidos por epitélio nos ossos gnáticos. Clinicamente pode estar associado a qualquer dente impactado, porém ele envolve com mais frequência os terceiros molares inferiores. Acomete pacientes entre 10 a 30 anos de idade, com predileção pelo sexo masculino, sendo na maioria dos casos detectados em exames radiográficos de rotina. O tratamento baseia-se nas técnicas de descompressão, marsupialização e enucleação. O prognóstico para os cistos dentígeros é altamente favorável e não há chance de recorrência após a remoção completa. Assim, a decisão terapêutica deve ser tomada de forma adequada para cada caso, levando em consideração a localização anatômica, extensão clínica, tamanho, idade, remoção do dente não irrompido e possibilidades de acompanhamento.

The aim of this integrative review was to carry out a qualitative assessment of the existing literature on the treatment modalities used for dentigerous cysts in pediatric patients. This study is an integrative literature review using the PubMed, VHL (Virtual Health Library), LILACS and SciELO databases. The inclusion criteria were articles published in full, clinical case reports, systematic reviews and meta-analysis published in the last 10 years, available in Portuguese or English, which addressed the subject. The exclusion criteria were: abstracts, annals, editorials, letters to the editor, reflection, duplication, articles with incomplete details. The dentigerous cyst is the most common type of developmental odontogenic cyst and the second most frequent of all those that occur in the jaws, accounting for around 20% of all epithelium-lined cysts in the gnathic bones. Clinically, it can be associated with any impacted tooth, but it most often involves the lower third molars. It affects patients between 10 and 30 years of age, with a predilection for males, and in most cases it is detected during routine radiographic examinations. Treatment is based on decompression, marsupialization and enucleation. The prognosis for dentigerous cysts is highly favorable and there is no chance of recurrence after complete removal. Therefore, the therapeutic decision must be made appropriately for each case, taking into account the anatomical location, clinical extension, size, age, removal of the unerupted tooth and follow-up possibilities.

Association between hyperglycemia and post-exodontia complications in patients with type ii diabetes mellitus: a scoping review / Asociación entre hiperglucemia y complicaciones post-exodoncia en pacientes con diabetes mellitus tipo ii: scoping review

Introduction: Diabetes mellitus (DM) is a prevalent chronic metabolic disorder worldwide, with Type II DM (T2DM) emerging as the most widespread variant. In Chile, approximately 11% of adults aged 20 to 79 suffer from this condition. Given its high prevalence, dental surgeons should be trained to evaluate risk factors, particularly the potential complications linked to tooth extraction in individuals with T2DM. Objetive: To describe the available scientific evidence on post-exodontia complications associated with hyperglycemia in patients with Type II diabetes mellitus. Materials and Methods: An exploratory systematic review was conducted following the PRISMA-ScR extension protocols using the databases PubMed, EBSCO, Scopus and the Cochrane Library. The search employed the following algorithms: (("Diabetic patient complications" AND "Dental extractions")), (("Diabetes" AND "tooth extraction")), (("Glycemia" AND "Tooth extraction complications"), (("Blood glucose" AND "Tooth extractions"), (("Dental extraction sockets" AND "Diabetics"). Results: Out of a total of 973 articles, 25 were included for this review. Six relevance criteria were considered, revealing safety parameters for conducting extractions in patients with T2DM, with capillary blood glucose levels not exceeding 200 mg/dL for elective extractions and 240 mg/dL for emergency extractions. Conclusions: There is limited evidence correlating threshold values of hyperglycemia with post-extraction complications in patients with T2DM. Most authors agree that the primary concern is not T2DM itself, but hyperglycemia. Furthermore, there is minimal consistency in the recommended care protocols for these patients.

Introducción: La diabetes mellitus (DM) es un trastorno metabólico crónico. A nivel mundial, la DM tipo II (DM2) resulta ser la más frecuente. En Chile, un 11% de la población adulta entre los 20 y 79 años la padece. Su alta prevalencia, requiere de un cirujano dentista preparado para valorar los factores de riesgo, como las posibles complicaciones asociadas a la extracción dental en estos pacientes. Objetivo: Describir la evidencia científica disponible sobre complicaciones post-exodoncia asociadas a hiperglicemia en pacientes con diabetes mellitus tipo II. Materiales y Métodos: Se realizó una revisión sistemática exploratoria bajo los protocolos de extensión PRISMA-ScR utilizando las bases de datos, PubMed, EBSCO, Scopus y Cochrane Library con los algoritmos de búsqueda (("Diabetic patient complications" AND "Dental extractions")), (("Diabetes"AND "Tooth extraction")), (("Glycemia" AND "tooth extraction complications")), (("Blood glucose" AND "Tooth extractions")), (("Dental extraction sockets"AND "Diabetics")). Resultado: De un total de 973 artículos se incluyeron 25 artículos para esta revisión. Se consideraron 6 criterios de pertinencia, los cuales mostraron parámetros de seguridad para realizar exodoncias, en pacientes con DM2, con la glucemia capilar no mayor a 200mg/dl en caso de ser electiva y 240 mg/dl en exodoncia de urgencias. Conclusión: Existe poca evidencia que correlacione valores absolutos de hiperglucemia y complicaciones post exodoncia en pacientes con DM2. La mayoría de los autores concuerda en que el problema no es la DM2, sino la hiperglucemia. Existe poca uniformidad en los protocolos de atención recomendados para estos pacientes.

Cost-effectiveness of preemptive pharmacological management of undesired effects in third molar extraction / Custo-efetividade do manejo farmacológico preemptivo de efeitos indesejados na exodontia de terceiros molares

ABSTRACT BACKGROUND AND OBJECTIVES: The extraction of third molars can lead to undesired effects such as pain, trismus, and edema, necessitating preemptive therapy to alleviate these effects. For this purpose, an economic evaluation was conducted to analyze the cost-effectiveness of preemptive drugs used in the extraction of third molars. METHODS: Costs were obtained from a market survey. Effectiveness measures were limitation of interincisal distance and postoperative pain, obtained from randomized clinical trials in the literature. For both models, a Monte Carlo simulation generated a hypothetical cohort of a thousand individuals, considering a 5% variation in estimates. The evaluated therapies were dexamethasone 8 mg (DX8); methylprednisolone 40 mg (MP); diclofenac 50 mg associated with tramadol 50 mg (DCTR); and dexamethasone 4mg associated with tramadol 50 mg (DXTR). RESULTS: MP and DCTR therapies were dominated in all scenarios. For the reduction of postoperative pain, DXTR treatment showed the best cost-benefit, with a net monetary benefit (NMB) gain of 31.10% compared to the lowest-cost treatment (DX, R$ 1.76). Considering the reduction in limitation of interincisal distance, DXTR medication presented higher cost-benefit compared to DX8 (NMB gain = 18.25%), being a preferred option alongside DX8. CONCLUSION: In the extraction of third molars, preemptive administration of dexamethasone 4mg associated with tramadol 50mg is the preferred cost-effective option to reduce postoperative pain and limitation of interincisal distance after 48 hours.

RESUMO JUSTIFICATIVA E OBJETIVOS: A exodontia de terceiros molares pode acarretar efeitos indesejados, como dor, trismo e edema, sendo necessário ofertar uma terapia preemptiva para amenizá-los. Para tal, realizou-se uma avaliação econômica para analisar o custo-efetividade de fármacos preemptivos utilizados na exodontia de terceiros molares. MÉTODOS: Os custos foram obtidos a partir de uma pesquisa de mercado. As medidas de efetividade foram: limitação da distância interincisal e dor pós-operatória, sendo obtidas em ensaios clínicos randomizados da literatura. Para os dois modelos, uma simulação de Monte Carlo gerou uma coorte hipotética de mil indivíduos, considerando uma variação de 5% das estimativas. As terapias avaliadas foram: dexametasona 8 mg (DX8); metilprednisolona 40 mg (MP); diclofenaco 50 mg associado a tramadol 50 mg (DCTR); e dexametasona 4 mg associada a tramadol 50 mg (DXTR). RESULTADOS: As terapias com MP e DCTR foram dominadas em todos os cenários. Para redução da dor pós-operatória, o tratamento com DXTR apresentou o melhor custo-benefício, com ganho de benefício monetário líquido (NMB) de 31,10% comparado ao tratamento de menor custo (DX, R$ 1,76). Considerando a redução da limitação da distância interincisal, o fármaco DXTR apresentou maior custo-benefício em relação à DX8 (ganho de NMB = 18,25%), sendo uma opção de escolha junto a DX8. CONCLUSÃO: Na exodontia de terceiros molares, a administração preemptiva de dexametasona 4 mg associada com tramadol 50 mg é a opção de escolha, do ponto de vista de custo-efetividade, para reduzir a dor pós-operatória e limitação da distância interincisal após 48 horas.

Manutenção de dentes retidos e associado com cisto dentígero após a marsupialização: série de casos / Maintenance of impacted teeth and associated with dentiger cyst after marsupialization: case series

Objetivo: O objetivo deste trabalho foi apresentar uma série de casos de manutenção de dentes retidos associados ao cisto dentígero (CD), empregando-se a marsupialização ou descompressão cística. Métodos: Realizou-se um estudo epidemiológico transversal, fundamentado na análise retrospectiva e descritiva dos registros do Serviço de Estomatologia e Cirurgia Bucomaxilofacial do HMOB (Hospital Metropolitano Odilon Behrens) entre novembro de 2005 a novembro de 2020. Resultados: Os resultados mostraram doze pacientes que receberam a marsupialização como tratamento do CD. Os dentes mais envolvidos foram pré-molares e incisivos centrais superiores e o tempo médio de erupção foi de 13 meses, sendo que a maioria das erupções ocorreram de forma espontânea. Em todos os casos verificou-se erupção do dente associado e neoformação óssea na região do cisto. Não foram observadas recidivas. Conclusão:Assim, baseado no presente estudo e na literatura, a marsupialização ou descompressão cística mostrou-se uma alternativa terapêutica eficiente na abordagem de pacientes jovens portadores de CD, inclusive, com o aproveitamento do dente associado ao cisto em casos selecionados.

Aim: The objective of this study was to present a series of cases of maintenance of impacted teeth associated with dentiger cyst (DC), using marsupialization or cystic decompression. Methods:A cross-sectional epidemiological study was carried out, based on a retrospective and descriptive analysis of the records of the Stomatology and Oral and Maxillofacial Surgery Service of the HMOB (Hospital Metropolitano Odilon Behrens) between November 2005 and November 2020. Results: The results showed twelve patients who received marsupialization as a treatment for DC. The most involved teeth were premolars and upper central incisors and the mean eruption time was 13 months, with most eruptions occurring spontaneously. In all cases, there was eruption of the associated tooth and new bone formation in the region of the cyst. No recurrences were observed. Conclusion: Based on the present study and the literature, marsupialization or cystic decompression is an efficient therapeutic alternative in approaching young patients with DC, including the use of the tooth associated with the cyst in selected cases.

Pacientes portadores da Doença de Chagas: manejo odontológico: uma revisão narrativa da literatura / Patients with Chagas Disease: dental management: a narrative literature review

A doença de Chagas é uma infecção parasitária sistêmica causada pelo protozoário Trypanosoma cruzi (T. cruzi), descoberta em 1909, pelo médico e pesquisador brasileiro, Carlos Chagas. O objetivo deste estudo é discutir sobre as manifestações clínicas da Doença de Chagas e suas importantes implicações na Odontologia. Este artigo é baseado em um estudo de revisão narrativa da literatura, de abordagem qualitativa. O levantamento dos artigos foi realizado na base de dados PubMed, LILACS e SciELO totalizando 13 estudos utilizados para o complemento da pesquisa. A Doença de Chagas é transmitida pelo contato com as fezes do inseto vetor, chamado de "barbeiro" no Brasil. Quando a célula, a qual o protozoário invadiu, se rompe, os novos microrganismos procuram novas células para habitar, percorrendo o sangue e a linfa, atingido o coração, tubo digestivo e plexos nervosos. Ao afetar o tecido coronariano, os microrganismos instalam-se nas células cardíacas, principalmente nos fagolissomos, além de afetar o sistema cardíaco, a doença de Chagas pode apresentar envolvimento de mais dois importantes sistemas do corpo humano: sistema estomatognático e digestivo. No atendimento a pacientes chagásicos, que apresentam comprometimento cardíaco, o Cirurgião-Dentista precisa realizar anamnese bem detalhada a fim de se conhecer mais sobre a condição sistêmica do mesmo, protocolos de redução de estresse são imprescindíveis considerando que o atendimento odontológico induz um quadro de ansiedade nos pacientes. O conhecimento prévio sobre a doença de chagas é mandatório para o Cirurgião-Dentista, visto que as manifestações bucais da doença podem impactar diretamente na qualidade de vida desses indivíduos.

Chagas disease is a systemic parasitic infection caused by the protozoan Trypanosoma cruzi (T. cruzi), discovered in 1909 by the Brazilian physician and researcher, Carlos Chagas. The aim of this study is to discuss the clinical manifestations of Chagas disease and its important implications in Dentistry. This article is based on a narrative review of the literature, with a qualitative approach. The survey of articles was carried out in the PubMed, LILACS and SciELO databases, totaling 13 studies used to complement the research. Chagas disease is transmitted by contact with the feces of the vector insect, called "kissing bug" in Brazil. When the cell, which the protozoan invaded, ruptures, the new microorganisms look for new cells to inhabit, traveling through the blood and lymph, reaching the heart, digestive tract and nervous plexuses. By affecting the coronary tissue, the microorganisms settle in the cardiac cells, mainly in the phagosomes. In addition to affecting the cardiac system, Chagas disease can involve two more important systems of the human body: the stomatognathic and digestive systems. When caring for chagasic patients who have cardiac involvement, the dentist needs to carry out a very detailed anamnesis in order to learn more about their systemic condition, stress reduction protocols are essential considering that dental care induces a picture of anxiety in patients. Prior knowledge about Chagas disease is mandatory for the dentist, since the oral manifestations of the disease can directly impact the quality of life of these individuals.

Bromelina e sua utilização na cirurgia buco-maxilo-facial / Bromelain and its use in oral and maxillofacial surgery / Bromelaína y su uso en cirugía oral y maxilofacial

Os medicamentos ditos naturais, denominados de fitoterápicos, são medicações que buscam atingir os resultados necessários das medicações ditas convencionais, porém sem os efeitos adversos decorrentes de alguns grupos medicamentosos. Em cirurgia Buco-Maxilo-Facial uma linha de pesquisa já consolidada e com importância significativa é o controle da dor e inflamação decorrentes dos procedimentos cirúrgicos Buco-Maxilo-Faciais. Um nutracêutico já descrito e pesquisado na literatura para substituir os anti-inflamatórios alopáticos e seus efeitos colaterais, principalmente os gastrointestinais e renais que são altamente indesejáveis, é a Bromelina. Ainda existe a necessidade de mais estudos relacionados a dose terapêuticas para diferentes tipos de cirurgia e outros nutracêuticos... (AU)

So-called natural medicines, called herbal medicines, are medications that seek to achieve the necessary results of so-called conventional medications, but without the adverse effects resulting from some drug groups. In Oral and Maxillofacial surgery, a line of research that is already consolidated and has significant importance is the control of pain and inflammation resulting from Oral and Maxillofacial surgical procedures. A nutraceutical already described and researched in the literature to replace allopathic anti-inflammatories and their side effects, mainly gastrointestinal and renal side effects, which are highly undesirable, is Bromelain. There is still a need for more studies related to therapeutic doses for different types of surgery and other nutraceuticals... (AU)

Autotransplante dentário: da previsibilidade à técnica cirúrgica e resultados do tratamento / Dental Autotransplantation: from predictability to surgical technique and treatment results

Objetivo: apresentar o relato de duas pacientes com agenesias dentárias em que cinco dentes autotransplantados foram utilizados como modalidade de tratamento. Além disso, objetiva-se mostrar questões sobre a técnica cirúrgica, suas indicações e previsibilidade. Relato de caso: Neste estudo, foram relatados 5 casos de autotransplante dentário em duas pacientes jovens, em que a equipe realizou os procedimentos e o acompanhamento clínico e radiográfico por 5 e 7 anos. Devido à alta sensibilidade da técnica, foram seguidos princípios previamente estabelecidos na literatura envolvendo o autotransplante dentário. Durante o período de acompanhamento, os dentes se mantiveram em posição e em função e as pacientes não apresentavam queixas associadas. Considerações finais: a técnica do autotransplante dentário, quando bem indicada e executada, é capaz de promover resultados bastante satisfatórios, sendo uma ótima alternativa reabilitadora, com taxas de sucesso elevadas e custos reduzidos. No entanto, critérios em relação aos sítios doadores e receptores e a habilidade do cirurgião devem ser levados em conta para o sucesso do técnica.

Objective: presenting the report of two patients with tooth agenesis in which five autotransplanted teeth were used as a treatment modality. Furthermore, the aim is to show questions about the surgical technique and its indications and predictability. Case report: In this study, 5 cases of dental autotransplantation were reported in two young patients, in which the team performed procedures and had clinical and radiographic follow-up for 5 and 7 years. Due to the high sensitivity of the technique, principles previously established in the literature involving dental autotransplantation were followed. During the follow-up period, the teeth remained in position and function and the patients had no associated complaints. Final considerations: the dental autotransplantation technique, when well indicated and executed, is capable of achieving very satisfactory results, being a great rehabilitative alternative, with high success rates and reduced costs. However, criteria regarding donor and receptor sites and the surgeon's skill must be taken into account for the success of the technique.

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.

Ameloblastoma uniquístico con patrón plexiforme: revisión de la literatura a propósito de un caso clínico / Unicystic ameloblastoma with a plexiform pattern: literature review regarding a clinical case

En 1827 el médico James William Cusack describió una lesión tumoral expansiva con características clínicas similares al ameloblastoma. Para el 2017 la Organización Mundial de la Salud lo clasificó como un tumor odontogénico benigno de origen epitelial. En la actualidad hemos aceptado la teoría de su etiología asociada con una mutación en el biomarcador BRAF-V600E, donde se presentan claras heterogeneidades extra/intratumorales en el metabolismo de la tumorogénesis; la mutación en BRAF genera cambios en la regulación de la odontogénesis, en conjunto con el gen CDC73 presente en el cromosoma 1 q25-q32, lo que produce un cambio en la proteína parafibromina que inhibe la proliferación celular durante el crecimiento y la división celular, esto afecta en conjunto al gen p53 y su homólogo p63 presentes en el cromosoma 17, por lo que se tiene como resultado la expresión de quistes y tumores dentales como el ameloblastoma. La presente obra muestra el caso clínico de un paciente femenino de 11 años de edad con aumento de volumen en la región submandibular izquierda de 7 × 4 cm, con seis años de evolución; de tal manera que fue diagnosticado con ameloblastoma uniquístico y tratado de forma conservadora mediante enucleación, posteriormente fue valorada anualmente hasta que la paciente cumplió los 18 años de edad (AU)

In 1827, physician James William Cusack described an expansive tumor lesion with clinical characteristics similar to ameloblastoma. For 2017, the World Health Organization classified it as a benign odontogenic tumor of epithelial origin. Currently, we have accepted the theory of its etiology associated with a mutation in the BRAF-V600E biomarker, where there are clear extra/intratumoral heterogeneities in the metabolism of tumorigenesis; the BRAF mutation generates changes in the regulation of odontogenesis, together with the CDC73 gene present on chromosome 1 q25-q32, producing a change in the parafibromin protein that inhibits cell proliferation during cell growth and division, which together it affects the p53 gene and its p63 homolog is present on chromosome 17, resulting in the expression of dental cysts and tumors such as ameloblastoma. This work provides the clinical case of an 11-year-old patient with an increase in volume in the left submandibular region of 7 × 4 cm of 6 years of evolution. Being diagnosed as a unicistic ameloblastoma and treated conservatively by enucleation, it is subsequently evaluated annually until the patient reaches 18 years of age (AU)

Interações potenciais entre os medicamentos comumente prescritos em cirurgia oral e os medicamentos em uso pelo paciente: estudo piloto / Potential interactions between drugs commonly prescribed in oral surgery and drugs used by the patient: a pilot study

Introdução: A alta prevalência do uso de medicamentos na população brasileira pode interferir na prescrição odontológica. Objetivos: Identificar os medicamentos em uso por pacientes atendidos em uma clínica de cirurgia oral menor e estimar os riscos de interações medicamentosas (IM) potenciais com fármacos comumente prescritos em procedimentos cirúrgicos. Materiais e Métodos: Realizou-se um estudo piloto analítico e transversal, sendo incluídos 24 pacientes atendidos na Clínica de Cirurgia Oral da Faculdade de Odontologia de uma universidade pública brasileira. Os dados foram coletados por meio de um questionário exploratório. Todos os medicamentos foram classificados no sistema Anatomical Therapeutic Chemical (ATC). As IM potenciais foram analisadas no banco de dados do Drugs® após correlação entre os medicamentos em uso pelo paciente e os medicamentos comumente prescritos em cirurgia oral.Resultados: Observou-se prevalência de 66,7% (n= 16) no uso de pelo menos 1 medicamento dentre os pacientes atendidos na clínica de cirurgia oral, com média de 3,5 (±2,2) medicamentos, sendo a polifarmácia identificada em 16,6% pacientes (n= 4). A média de idade dos usuários de medicamentos foi de 52 (±16) anos e totalizou-se 56 medicamentos. Os fármacos mais prevalentes foram aqueles atuantes nos sistemas nervoso e cardiovascular. Quando simuladas as adições dos fármacos comumente prescritos em cirurgia oral (anti-inflamatórios, analgésicos e antimicrobianos) aos medicamentos em uso pelos 16 pacientes, identificou-se 75 IM potenciais diferentes, sendo 61 (81%) de gravidade moderada e 14 (19%) de gravidade alta. As IM potenciais mais frequentes foram de anti-hipertensivos com anti-inflamatórios, enquanto as de importância clínica grave envolveram fármacos de ação central e analgésicos opioides. Conclusão: Observou-se alta prevalência na utilização de medicamentos pelos pacientes atendidos na clínica de cirurgia oral, com importante risco de interações com medicamentos prescritos em procedimentos cirúrgicos.

Introduction: The high prevalence of drug use in the Brazilian population can interfere with dental prescriptions.Objective: To identify drugs being used by patients seen at a minor oral surgery clinic and to estimate the risks of potential drug interactions (DI) with drugs commonly prescribed in surgical procedures. Materials and Methods: An analytical and cross-sectional pilot study was carried out, including 24 patients treated at the Oral Surgery Clinic of the Dental School of a Brazilian Federal University. Data were collected through an exploratory questionnaire. All drugs were classified in the Anatomical Therapeutic Chemical (ATC) system. Potential DI were analyzed in the Drugs® database after correlation between the drugs used by the patient and the drugs commonly prescribed in oral surgery.Results: There was a prevalence of 66.7% (n= 16) in the use of at least 1 medication among patients seen at the oral surgery clinic, with a mean of 3.5 (±2.2) medications, with polypharmacy identified in 16.6% patients (n= 4). Mean age of medication users was 52 (±16) years, totaling 56 medications. The most prevalent drugs were those acting on the nervous and cardiovascular systems. When the additions of drugs commonly prescribed in oral surgery (anti-inflammatory drugs, analgesics and antimicrobials) to the drugs used by the 16 patients were simulated, 75 different potential DI were identified, 61 (81%) of moderate severity and 14 (19%) of high gravity. The most frequent potential DIs were antihypertensives with anti-inflammatory drugs, while those of serious clinical importance involved centrally acting drugs and opioid analgesics. Conclusion: There was a high prevalence of medication use by patients seen at the oral surgery clinic, with a significant risk of interactions with prescribed medications in surgical procedures.

Salvage Mandibulectomy in an Octogenarian with Recurrent Oral Cavity Squamous Cell Carcinoma: A Case Report

@#Oral squamous cell carcinoma (OSCC) is the commonest malignant tumour affecting the oral cavity with a poor 5-year disease free survival. We present an octogenarian with a recurrent oral cavity squamous cell carcinoma, treated with salvage mandibulectomy without bony reconstruction. No immediate or intermediate perioperative complications were documented. Subsequent monthly surveillance clinical examination, endoscopy and computed tomography at six months post-operative showed no evidence of residual tumour. Geriatric syndrome, perioperative risk and oncologic stratification are three main cornerstones in evaluating feasibility of oncologic surgery in an elderly patient. A multidisciplinary approach allowed surgical extirpation of OSCC with a good outcome

Evolución histórica de la prótesis bucomaxilofacial en Camagüey

Introducción: Los principios en que se sustenta el proceso revolucionario cubano y su Sistema Nacional de Salud, es tratar de dar solución a las necesidades de la población y Cuba dentro de sus limitaciones de desarrollo, ha producido cambios en las condiciones de salud, a través de su política estatal. Objetivo: Describir la evolución histórica de la prótesis bucomaxilofacial en la provincia Camagüey. Métodos: Se realizó una revisión de la de literatura, para recopilar los datos de la historia de la prótesis bucomaxilofacial. Se ejecutó una búsqueda de la literatura en las bases de datos Pubmed, Medline, Cochrane, SciELO, Hinari y prensa escrita donde se expusieran las evidencias disponibles sobre los antecedentes de prótesis bucomaxilofacial en Cuba y en la provincia Camagüey. Resultados: En Cuba la prótesis maxilofacial antes del triunfo revolucionario prácticamente no se realizaba. El 14 de junio de 1999 se crea la Red Asistencial Nacional de Rehabilitación de la Cara y Prótesis Bucomaxilofacial y en el año 2001 el Programa de Rehabilitación de la Cara y Prótesis Bucomaxilofacial, con una cobertura para todos los pacientes del país con esta necesidad de atención. En Camagüey con la creación en abril de 1975 de la consulta multidisciplinaria de Estomatología se inició la atención a los pacientes con defectos bucomaxilofacial. Esto permitió rehabilitar en esos momentos a estos enfermos con los recursos disponibles. Conclusiones: El análisis y las valoraciones realizadas determinaron que la prótesis en la provincia Camagüey ha tenido un gran desarrollo tanto asistencial como docente e investigativo, aunque no se cuenta con un servicio dedicado a la prótesis bucomaxilofacial, se han realizados labores de rehabilitación a pacientes con estos defectos, que le han permitido recuperar la estética, el estado psíquico funcional con alto grado de aceptación y satisfacción y el logro de su reincorporación a la vida social.

Introduction: The principles on which the Cuban revolutionary process and its National Health System are based, is to try to provide a solution to the needs of the population, and Cuba within its development limitations, has produced changes in health conditions, through of its state policy. Objective: To describe the historical evolution of the bucomaxillofacial prosthesis in Camagüey. Methods: A review of the literature was carried out to collect the data on the history of the bucomaxillofacial prosthesis. A search of the literature was carried out in the Pubmed, Medline, Cochrane, SciELO, Hinari and written press databases where the available evidence on the history of oral-maxillofacial prostheses in Cuba and in the Camagüey province was exposed. Results : In Cuba, before the revolutionary triumph, maxillofacial prostheses were practically not performed. On June 14, 1999, the National Assistance Network for the Rehabilitation of the Face and Bucomaxillofacial Prosthesis was created, and in 2001 the Program for the Rehabilitation of the Face and Bucomaxillofacial Prosthesis, with coverage for all patients in the country with this need for care. In Camagüey, with the creation in April 1975 of the multidisciplinary Dentistry consultation, care began for patients with oral-maxillofacial defects. This made it possible to rehabilitate these patients at that time with the resources available. Conclusions: The analysis and the evaluations carried out determined that the prosthesis in Camagüey province has had a great development in terms of care, teaching and research, although there is no service dedicated to oral and maxillofacial prostheses, rehabilitation work has been carried out on patients with these defects, which have allowed them to recover their aesthetics, their functional mental state with a high degree of acceptance and satisfaction, and the achievement of their reincorporation into social life.

Variations in Function and Vocal Acoustic Characteristics After Orthognathic Surgery: Preliminary Results

ABSTRACT Objective: To determine the effects of orthognathic surgery on oral function and vocal quality in order to assess the need for speech therapy after surgery. Material and Methods: Thirty-seven patients scheduled for mono-jaw surgery, specifically maxillary (G1:15 patients), mandibular advancement (G2:10 patients) or mandibular set-back (G3:12 patients), were recruited for this prospective cohort study. Evaluation of oral functions, video recordings of speech articulation and audio recordings of voice were obtained before surgery (T0), and at 1 (T1) and 6 months (T2) after surgery. Spectrographic analysis and self-evaluation questionnaire regarding the vocal performance (VAPP) were performed. Both qualitative and quantitative statistical analysis was performed, mainly using generalized linear models for dichotomous data (p<0.05). Results: The formant frequencies (F1 and F2) of the main vowels vary after orthognathic surgery according to the type of surgery. Before surgery, 84% of patients analyzed showed difficulties in breathing and positioning the tongue both at rest and swallowing. Thanks to surgical correction of the malocclusion, the major part of these issues were resolved within 6 months. In 25% of cases, a change in the voice and/or articulation had occurred. Conclusion: Vocality improves after orthognathic surgery and it changes in relation to the type of surgery. However, vocality did not normalize completely. Speech assessment should be considered after surgery in order to offer adequate speech therapy if necessary.

Surgery traction canine of impacted in the maxillary: a case report / Cirurgia de tracionamento de canino impactado em maxila: relato de caso

ABSTRACT Permanent canines are essential for the preservation of the stomatognathic system, as they are part of the occlusal and aesthetic function and balance. During the normal development of occlusion, canines follow a long and complex trajectory until their eruption, that is, they are more likely to suffer disturbances during this process. Removal of the permanent canine should only be considered in extreme cases, where the canine itself is not susceptible to orthodontic traction. Orthodontic traction is the most indicated treatment due to the high morphofunctional and aesthetic value of the permanent canine. The aim of this study is to report a clinical case of traction surgery of the superior permanent canine included in the maxilla. A 13-year-old female patient attended the dental clinic at the Nilton Lins University accompanied by her guardian, referred by an orthodontistfor canine traction surgery. during the examIn the clinical analysis, tooth 13 was absent from the dental arch. The patient had a computed tomography scan, where it was possible to verify the actual position of the toothimpacted with the partially erupted crown on the alveolar ridge. After planning, surgery was performed to install an orthodontic button and adapt the ligature with a 0.30 mm wire. After the 10-month follow-up period, the presence of the tooth in arch, completely erupted, was observed, showing effectiveness in the proposed treatment. Therefore, the procedure for bonding the orthodontic device was performed satisfactorily without complications or intercurrences, making it possible to continue the orthodontic treatment. The patient remains under follow-up.

RESUMO Os caninos permanentes são essenciais para a preservação do sistema estomatognático, visto que, fazem parte da função e equilíbrio oclusal e estético. Durante o desenvolvimento normal da oclusão, os caninos seguem uma longa e complexa trajetória até seu irrompimento, ou seja, estão mais propensos a sofrerem distúrbios no decorrer desse processo. A extração do canino permanente só deve ser considerada em casos extremos, onde o próprio não se encontra suscetível à tração ortodôntica. O tracionamento ortodôntico é o tratamento mais indicado devido ao alto valor morfofuncional e estético do canino permanente. Sendo assim, o objetivo deste estudo é relatar um caso clínico de cirurgia de tracionamento de canino permanente superior incluso em maxila. Paciente de 13 anos, gênero feminino, compareceu a clínica odontológica da Universidade Nilton Lins acompanhado de seu responsável, encaminhada por um ortodontista para cirurgia de tracionamento de canino. Durante o exame clínico observou-se ausência do dente 13 na arcada dentária. A paciente apresentou a tomografia computadorizada, onde foi possível verificar o real posicionamento do dente impactado com a coroa parcialmente irrompida no rebordo alveolar. Após o planejamento, realizou-se a cirurgia destinada a instalação de botão ortodôntico e adaptação da amarrilha com fio 0,30 mm. Posteriormente ao período de acompanhamento de 10 meses, observou-se a presença do dente em arco, totalmente erupcionado, mostrando efetividade no tratamento proposto. Portando, o procedimento de colagem de dispositivo ortodôntico ocorreu de forma satisfatória sem complicações ou intercorrências, tornando possível a continuidade do tratamento ortodôntico. A paciente permanece em acompanhamento.

Actinomycosis in the maxilla of a young asymptomatic patient: unusual case report / Actinomicose em maxila de um paciente jovem assintomático: relato de caso incomum

ABSTRACT The aim of this study is to report an unusual case of actinomycosis in the maxilla region of an asymptomatic patient. A 21-year-old white man was referred for the analysis of panoramic radiography and cone beam computed tomography, where it was observed the presence of a hypodense lesion on the left side of the maxilla, which extended from the maxillary left central incisor to the region of the maxillary left second premolar. During intraoral examination, a depression was observed in the hard palate mucosa, as well as a fistula in the alveolar mucosa close to maxillary left central incisor, which had pulp vitality confirmed by thermal tests. A fistulography was performed, with periapical radiography, where it was found that the fistulous path did not originate from the tooth mentioned above. An incisional biopsy was performed for diagnostic purposes. However, given the inconclusive microscopic findings, four months later, a new biopsy was performed. The histopathological examination revealed the presence of a colony of microoganisms with filamentous pattern of radiated rosette, surrounded by polymorphonuclear inflammatory cells. Based on the morphological characteristics, the diagnosis of actinomycosis was established. The treatment was based on antibiotic therapy. Six months after treatment of the infection, no signs of recurrence were observed, and the patient remains in follow-up. Actinomycosis in the maxilla is an uncommon infection with a predilection for males between the ages of 20 and 60, whose treatment is antibiotic therapy associated or not with surgical excision.

RESUMO O objetivo deste estudo é relatar um caso incomum de actinomicose em região de maxila de um paciente assintomático. Um homem de 21 anos, branco, foi encaminhado para análise de radiografia panorâmica e tomografia computadorizada de feixe cônico, onde foi observada a presença de lesão hipodensa do lado esquerdo da maxila, que se estendia da região do incisivo central superior esquerdo ao segundo pré-molar superior esquerdo. Ao exame intrabucal, observou-se depressão na mucosa do palato duro, bem como fístula na mucosa alveolar próxima ao incisivo central superior esquerdo, no qual tinha vitalidade pulpar confirmada pelos testes térmicos. Uma fistulografia com radiografia periapical foi realizada, onde foi observado que o trajeto fistuloso não era originado do dente mencionado anteriormente. Foi realizada biópsia incisional para fins diagnósticos. Porém, diante dos achados microscópicos inconclusivos, quatro meses depois, uma nova biópsia foi realizada. O exame histopatológico revelou a presença de colônia de microrganismos com padrão filamentoso de roseta irradiada, circundado por células inflamatórias polimorfonucleares. Com base nas características morfológicas, foi estabelecido o diagnóstico de actinomicose. O tratamento foi baseado em antibioticoterapia. Seis meses após o tratamento da infecção, não foram observados sinais de recidiva e o paciente permanece em acompanhamento. A actinomicose da maxila é uma infecção incomum, com predileção por pacientes do sexo masculino com idade entre 20 e 60 anos, cujo tratamento é antibioticoterapia associada ou não à excisão cirúrgica.

Análise quantitativa de frenectomias realizadas no contexto do SUS após obrigatoriedade do teste da linguinha / Quantitative analysis of frenectomies performed in the context of the SUS after mandatory tongue test

RESUMO Buscou-se investigar e conhecer a frequência e a distribuição de frenotomias e fenectomias realizadas no Sistema Único de Saúde (SUS) após os dispositivos legais que instituíram o teste da linguinha, bem como entender quais profissionais estão realizando o procedimento cirúrgico. Estudo descritivo analítico, retrospectivo, com dados secundários, disponíveis no Sistema de Informações Ambulatoriais do DataSUS, extraídos por meio do TabWin. Observou-se um aumento considerável no número de procedimentos, porém, com flutuações nos anos seguintes. Das frenectomias registradas no SUS, no período, 33% foram realizadas por dentistas na atenção primária. Os resultados apontaram que houve um aumento substancial no número de procedimentos cirúrgicos em dois momentos, em 2014 e em 2017, possivelmente em decorrência da publicação da Lei nº 13.002/2014 e da Nota Técnica (NT) nº 09/2016. A NT nº 35/2018 deslocou o diagnóstico e o tratamento para a média complexidade, possivelmente resultando em filas, principalmente em se tratando de cirurgias que poderiam ser realizadas na atenção primária. Apesar de não haver unanimidade quanto à correlação anquiloglossia e desmame, não parece haver um monitoramento para evitar cirurgias desnecessárias, uma vez que a ordenha pode não ser afetada e o acompanhamento ser realizado para confirmar ou não essa necessidade.

ABSTRACT This study sought to investigate and to know the frequency and the distribution of frenotomies and frenectomies performed in the Unified Health System (SUS) after the legal provisions that instituted the tong test, and to understand which professionals are performing the surgical procedure. This is an analytical, descriptive, retrospective study, with secondary data, available in the DATASUS Information System. It was observed that a considerable increase in the number of procedures, but with fluctuations in the following years. Out of the frenectomies registered in the SUS in the period, 33% were performed by dentists in primary care. The results showed that there was a substantial increase in the number of surgical procedures in two moments, in 2014 and in 2017, possibly as a result of the publication of Ordinance nº 13.002/2014 and Technical Note (NT) No. 09/2016. NT No. 35/2018 shifted diagnosis and treatment to medium complexity, possibly resulting in queues, especially in the case of surgeries that could be performed in primary care. Although there is no unanimity regarding the correlation between ankyloglossia and weaning, there seems to be no monitoring to avoid unnecessary surgeries, since milking may not be affected and follow-up is carried out to confirm or not this need.

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

A systematic review assessing occurrence of medication-related osteonecrosis of the jaw following dental procedures

Aim: This study aimed to systematically review existing literature regarding the association between dental procedures­such as tooth extractions and periodontal therapy­and occurrence of medication-related osteonecrosis of the jaw (MRONJ) in individuals using bone-modifying drugs. Methods: Search strategies were performed in PubMed, Scopus, Web of Science and Cochrane Library for a timeframe ending in December 2021. Study selection, data extraction and risk of bias were analyzed independently by two researchers. Three meta-analyses were performed, estimating the crude risk ratio (RR), the adjusted odds ratio (OR) and the adjusted hazard ratio (HR) for the association between tooth extraction and MRONJ. Results: Of the 1,654 studies initially retrieved, 17 were ultimately included. The majority of patients with MRONJ in these studies were female, with a mean age of 64 years. Zoledronic acid was the most commonly used drug among patients with MRONJ, and cancer was the most frequent underlying health condition. Regarding the performed meta-analyses, crude and adjusted analyses demonstrated that tooth extraction increased the risk for MRONJ by 4.28 (95% confidence interval [95%CI]: 1.73­10.58), the OR for MRONJ by 26.94 (95%CI: 4.17­174.17), and the HR for MRONJ by 9.96 (95%CI: 4.04­24.55). Conclusion: It was concluded that performing dental procedures, especially tooth extraction, in patients using bone-modifying drugs increased the risk of MRONJ occurrence and, therefore, should be avoided. Further studies, using adjusted data, are warranted
