Pain and root resorption due to surgical interventions to accelerate tooth movement in orthodontics: A systematic review and meta-analysis.

BACKGROUND: There are several publications that show the efficacy of surgical interventions in accelerating the rate of tooth movement in orthodontics. Consequently, possible adverse effects must also be evaluated. OBJECTIVES: The aim of the present study was to compare the perception of pain and root resorption between orthodontic treatment with a surgical acceleration intervention vs. conventional orthodontic treatment. MATERIAL AND METHODS: An electronic search was conducted in the MEDLINE, Scopus, Web of Science (WoS), ScienceDirect, Cochrane Library, and Virtual Health Library (VHL) databases up to September 12, 2022. Randomized or non-randomized, controlled, parallel-arm or split-mouth clinical trials were included. Fixed-and random-effects meta-analyses were performed with regard to heterogeneity. The risk of bias (RoB) was assessed using the RoB 2.0 and ROBINS-I tools. RESULTS: A total of 1,395 articles were initially retrieved, 40 studies were finally included in the review and 15 studies were eligible for quantitative analysis. The meta-analysis showed a significant difference in pain perception between acceleration surgery vs. conventional orthodontics at 24 h (p = 0.040); however, this difference was not significant at 7 days (p = 0.080). Overall, the patients who underwent any acceleration procedure presented significantly less resorption as compared to those who were applied conventional treatment (p < 0.001). A similar significant difference was found in retraction movements (p < 0.001) and alignment movements (p = 0.030). CONCLUSIONS: In the first 24 h, surgical interventions for the acceleration of tooth movement produce a greater perception of pain as compared to conventional orthodontic treatment, but the perception is similar after 7 days. Acceleration surgery results in less root resorption - in alignment movements, and especially in retraction movements.

Minimally invasive sagittal osteotomy-technical note.

This article describes a novel minimally invasive technique for bilateral sagittal split osteotomy (BSSO) that aims to reduce surgical trauma while maintaining bone overlap and rigid internal fixation for proper consolidation of the bone segments. The technique involves a small vestibular mucoperiosteal incision made on the lateral aspect of the mandible between the first and second molars, enabling a standard ramus split, surgical segment movement, and miniplate fixation. A retrospective evaluation of 67 consecutive patients who underwent BSSO using this protocol showed favorable split of the mandible with no unfavorable splits or non-union. Patients were discharged from hospital within an average of 17 h with minimal postoperative complications. This technique provides good surgical visualization with a very small incision and allows standard BSSO surgery without difficulty.

Use of platelet- and leukocyte-rich fibrin (L-PRF) as a healing agent in the postoperative period of third molar removal surgeries: a systematic review.

OBJECTIVE: The aim of this study was to analyze the effectiveness of L-PRF as a healing agent in the postoperative period of third molar extraction surgeries, as well as to investigate secondary effects, such as the reduction of pain, edema and other discomforts after the surgical intervention. MATERIALS AND METHODS: The methodology adopted consisted of carrying out a systematic review of the literature, following the model outlined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The inclusion criteria were previously established according to a systematic review protocol approved by the Prospective Register of Systematic Reviews (PROSPERO) under number CRD42023484679. In order to carry out a comprehensive search, a search in five databases was carried out, PubMed, Web of Science, Scopus, Cochrane Library and Embase. RESULTS: The search resulted in the selection of randomized controlled trials that conformed to the established criteria. Two authors independently screened the records and extracted the data. The assessment of bias was conducted according to the guidelines recommended by the Cochrane Collaboration, using version 2 of the Cochrane tool for assessing the risk of bias in randomized trials (RoB 2). CONCLUSION: This study demonstrated that L-PRF stands out by providing direct benefits to healing, vascularization and tissue regeneration. CLINICAL RELEVANCE: L-PRF plays an important role in reducing postoperative pain, edema, the incidence of alveolar osteitis and infections after third molar removal surgery, compared to patients who did not undergo the use of L-PRF.

The influence of electrical high-speed rotation on mandibular third molar surgeries: a prospective, randomized, split-mouth clinical and radiographic study.

The aim of this split-mouth randomized clinical trial was to evaluate the clinical outcomes (operative time, edema, trismus, and pain), the immediate histological effects, the alveolar repair (2 and 4 months), and the quality of life after the extraction of impacted third molars using high-speed pneumatic and electrical rotation. Sixteen patients underwent extraction of the two mandibular third molars with a minimum interval of 15 days. On one side of the participant's mouth, high-speed pneumatic rotation was used (Control Group-CG) while for the other side, high-speed electrical rotation was used (Study Group-SG). Statistical analysis included ANOVA repeated measures and Pearson correlations. SG group showed: shorter operative time (p = 0.019), less pain (p = 0.034), swelling (p < 0.001) and trismus (p = 0.025) on the 1st postoperative day; less pain (p = 0.034) and trismus (p = 0.010) on the 3rd postoperative day; less trismus (p = 0.032) on the 7th postoperative day; and better quality of life (p = 0.007). No differences were observed for peripheral bone damage or bone density of alveolar repair at 2 and 4 months between groups. Electric high-speed rotation provided better postoperative clinical parameters of pain, edema and trismus when compared with pneumatic high-speed rotation for mandibular third molar surgery.Trial registration: Brazilian Registry of Clinical Trials registration number RBR-4xyqhqm ( https://ensaiosclinicos.gov.br/rg/RBR-4xyqhqm ).

Del total de artículos, 6 corresponden a terapia láser de bajo nivel, 2 a medicación y bloqueo del ganglio estrellado, 1 a bloqueo de ganglio estrellado e irradiación con luz xenón y 5 artículos corresponden a tratamiento mediante reparación microquirúrgica. La terapia láser de bajo nivel, el bloqueo del ganglio estrellado, la administración de vitamina B12/ATP y la reparación microquirúrgica son tratamientos efectivos para las alteraciones neurosensoriales ocasionadas por lesiones del nervio alveolar inferior y nervio lingual.

SUMMARY: Neurosensory abnormalities are complications can occur after performing certain oral surgical procedures. Multiple reports specifically indicate the area innervated by the inferior alveolar nerve and the lingual nerve as the most affected regions. Presenting the different therapeutic alternatives for these complications would be extremely relevant for the clinician, in order to improve the prognosis in terms of neurosensory recovery of these nerves. The objective of this study was to describe the therapeutic management of neurosensory abnormalities associated with damage to the inferior alveolar nerve and lingual nerve, in mandibular surgical procedures. The search for scientific literature was carried out in the PubMed, Scopus and Web of Science databases. The search terms "Trigeminal nerve injuries", "lingual nerve", "mandibular nerve", "oral surgical procedures", "treatment" together with the boolean connector "AND" and "OR" were used. Articles published between the years 2012 and 2022 were considered. In the selection of primary articles, duplicates were eliminated and the inclusion and exclusion criteria were applied. Finally, the full text analysis was carried out with a total of 14 selected articles. A total of 14 articles were reviewed. About the articles, 6 correspond to low-level laser therapy, 2 to medication and stellate ganglion block, 1 to stellate ganglion block and xenon light irradiation, and 5 articles correspond to treatment by microsurgical repair. Low-level laser therapy, stellate ganglion block, vitamin B12/ATP administration, and microsurgical repair are effective treatments for neurosensory abnormalities caused by inferior alveolar nerve and lingual nerve injuries.

Efficacy of analgesia promoted by lidocaine and articaine in third molar extraction surgery. A split-mouth, randomized, controlled trial.

PURPOSE: The aim of this study was to compare the analgesic efficacy of 4% articaine associated with epinephrine (1:100,000), and 2% lidocaine associated with epinephrine (1:100,000) in third molar extraction surgery. METHODS: Sixty patients who underwent surgeries to extract upper and lower third molars were included in this split-mouth, double-blind, randomized, controlled trial. The groups in this study were divided according to the anesthetic solution used to provide local anesthesia during extraction of upper and lower third molars: (1) 4% articaine associated with epinephrine (1:100,000); (2) 2% lidocaine associated with epinephrine (1:100,000). The time to the beginning and end of the sensation of analgesia, pain sensation according to the VAS scale, and number of anesthetic tubes necessary for supplementation were analyzed. RESULTS: It was found that the onset time for analgesia was shorter on the side anesthetized with articaine compared to the side anesthetized with lidocaine (122.1 ± 52.90 s vs. 144.5 ± 68.85 s) (p < 0.05). In addition, the number of tubes used for anesthetic supplementation was also reduced on the articaine side compared to the lidocaine side (0.26 ± 0.48 vs. 0.50 ± 0.75) (p < 0.05). There were no differences between the anesthetic solutions in the other evaluated parameters. CONCLUSION: It can be concluded that the use of 4% articaine associated with epinephrine (1:100,000) reduced the time of onset of analgesia and the necessity for anesthetic supplementation in third molar extraction surgeries compared to the use of 2% lidocaine associated with epinephrine (1:100,000).

Clinicopathological characteristics of odontogenic carcinosarcoma: A systematic review.

BACKGROUND: The aim of the present systematic review was to summarize evidence on odontogenic carcinosarcoma, analyzing clinical, epidemiological, imaging, histopathological, immunohistochemical, therapeutic, and prognostic features of this tumor. MATERIALS AND METHODS: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Searches were performed in the Ovid MEDLINE (Wolters Kluwer), PubMed (National Library of Medicine), Web of Science (Thomson Reuters), Scopus (Elsevier), and LILACS (Latin American and Caribbean Center on Health Sciences Information) databases, without publication date or language restrictions. Case reports or case series of OCS reporting clinical, radiological, and histopathological data that confirmed the diagnosis were selected. The Joanna Briggs Institute-University of Adelaide tool was used for critical appraisal of the included articles. RESULTS: Odontogenic carcinosarcoma is a rare, aggressive tumor associated with high mortality; however, the metastasis rate is low. The tumor has a male predilection. The mean patient age is 40 years, but there is no predilection for age. The left posterior mandible is the most affected site, but no specific radiographic features have been reported. CONCLUSION: Given its rarity, dentists, oral-maxillofacial surgeons, and physicians need to be aware of odontogenic carcinosarcoma in order to increase the diagnostic potential, preventing delays in diagnosis and treatment and thus contributing to lower morbidity of the tumor.

Conhecimento do cirurgião-dentista sobre as implicações judiciais embutidas na cirurgia estética de bichectomia / Knowledge of the dentist on the judicial implications embedded in aesthetic surgery of bichectomy

Objetivo: Analisar se os cirurgiões-dentistas têm conhecimento das implicações judiciais embutidas na cirurgia estética de bichectomia. Métodos: Trata-se de um estudo descritivo no qual foi aplicado um questionário estruturado aos docentes cirurgiões-dentistas da Faculdade Maria Milza (FAMAM) que realizam bichectomia. Os dados do questionário foram organizados em forma de tabela, apresentando informações sociodemográficas e sobre o conhecimento deles em relação aos aspectos judicias embutidos neste tipo de cirurgia. Resultados: A amostra foi composta por 08 cirurgiões-dentistas, docentes da Faculdade Maria Milza. A maioria era do sexo masculino, com idade entre 29 a 39 anos, com tempo de docência menor igual a 5 anos e atuando em clínica privada. A maioria afirmou estar ciente das possíveis implicações judiciais e se previnir destas, no entanto, grande parte da amostra estudada não tinha conhecimento do Código Civil Brasileiro. Conclusão: A maioria dos dentistas não possuíam conhecimento sobre o Código Civil Brasileiro, mas sabem que podem responder processos movidos pelos pacientes. Frente a isso, eles estão se protegendo de possíveis implicações de ordem judicial relacionados a cirurgia de bichectomia.(AU)

Objective: To analyze whether dentists are aware of the judicial implications embedded in cosmetic surgery for bichectomy. Methods: This is a descriptive study in which a structured questionnaire was applied to the professors-dentists at Faculdade Maria Milza (FAMAM) who perform bichectomy. The questionnaire data were organized in form of a table, presenting sociodemographic information and their knowledge in relation to the judicial aspects embedded in this type of surgery. Results: The sample consisted of 08 dental surgeons, professors at Faculdade Maria Milza. Most were male, aged between 29 and 39 years old, with less than 5 years of teaching experience and working in a private clinic. The majority claimed to be aware of the possible legal implications and to prevent them, however, a large part of the sample studied was not aware of the Brazilian Civil Code. Conclusion: Most surgeons had no knowledge of the Brazilian Civil Code, but they know that they can respond to a lawsuit brought by patients. Faced with this, they are protecting themselves from possible implications of a court order related to bichectomy surgery.(AU)

Postoperative pain after third molar extraction surgery in patients with and without bruxism: an observational study.

Third molar extraction surgery is a frequentprocedure in dentistry. Like any surgical procedure, it may lead to inflammatory responses, and postoperative pain is one of its main complications. Furthermore, temporomandibular disorder (TMD) is a collective termfor several clinicalproblems involving orofacial structures. Patients withparafunction are more sensitive to mechanical stimuli such as pressure during surgical procedures. Aim: To analyze postoperative pain in patients with and without bruxism subjected to third molar extraction surgery. Materials and Method: This was an observational study including four groups with a 1:1:1:! allocation ratio, conducted following ethical approval. Patients classified as ASA I with an indication for lower third molar extraction were recruited. Bruxism was self-reported. Two surgical techniques were used: one with only forceps and levers (ST1) and another with osteotomy and odontosection (ST2). Results: Four groups (bruxism and surgical techniques) were enrolled, each with a convenience sample (n=34). Postoperative pain levels were higher in patients with than without bruxism (p<0.05). The comparison between surgical techniques showed significantly higher pain levels only on the seventh day for ST2 groups (p<0.05). Oral mucosaflap incisions did not cause significantly higher persistence and pain levels. Conclusions: Bruxism, osteotomy, and odontosection may have increased postoperative pain levels, whereas performing an oral mucosa flap did not cause significant differences. Nevertheless, these preliminary data should be interpreted carefully. Randomized controlled trials are required to reinforce the findings of this study.

Evaluation of Antibiotic Prophylaxis Prescriptions for Infectious Endocarditis Before Oral Procedures Between Cardiologists and Dentists

Abstract Background Infective endocarditis (IE) is a serious disease with a high mortality rate. Antibiotic prophylaxis for bacterial endocarditis before invasive procedures has been recommended in patients with predisposing cardiac conditions since 1960, but contemporary guidelines worldwide have proposed changes. Objective To evaluate the knowledge and pattern of prescription by cardiologists and dentists regarding antibiotic prophylaxis for bacterial endocarditis before risky oral procedures. Methods This is an observational and cross-sectional study. Data were obtained from an online questionnaire, sent to cardiologists and dentists linked to specialty societies, in the first semester of 2021. Data analysis was performed using descriptive statistics, and comparisons between variables were done in an exploratory approach. The significance level adopted was 5%. Results From 613 responders, 82.5% of cardiologists and 79.5% of dentists reported prescribing antibiotic prophylaxis for patients at high and moderate risk for IE. Of dental procedures capable of generating bacteremia, all were correctly identified by more than 50.0% of the sample. As for the habits of daily living, flossing and toothbrushing had almost 50.0% of correct answers, chewing had only 17.3%, and 40.9% reported that none of the actions presented a risk of bacteremia. When comparing variables, the correct prescription of amoxicillin (2 g, 30-60 minutes before the procedure) was more prevalent among cardiologists and in responders with less than 20 years of graduation (p<0.01). Conclusion In the present study, the prescription of antibiotic prophylaxis for IE were frequent for high- and moderate-risk patients, before oral/dental procedures. Partial knowledge was found about endocarditis, which highlights the need for continuous medical/dental education.

Use of platelet concentrates in oral surgery of patients with osteonecrosis: a scoping review

Abstract The objective of this study was to map, through a scoping review, the evidence available in the literature on the use of platelet concentrates in compromised patients undergoing oral surgeries. Searches were performed in electronic databases for clinical studies with compromised patients undergoing oral surgery who used platelet concentrates. Only studies published in English were included. Two independent researchers carried out the selection of studies. The study design and objective, surgical procedure and platelet concentrate used, systemic involvement, analyzed outcome, and main results were extracted. A descriptive analysis of the data was performed. Twenty-two studies met the eligibility criteria and were included. Case series was the most frequent study design among the included studies (41.0%). In terms of systemic disability, 19 studies reported patients with cancer and related to surgical treatment 16 studies reported patients underwent treatment for osteonecrosis related to the use of the drug. The most used platelet concentrate was pure platelet-rich fibrin (P-PRF). In general, most studies recommend the use of platelet concentrates. Thus, the results of this study suggest that the evidence related to the use of platelet concentrates in compromised patients when undergoing oral surgeries is still initial. Also, most studies assessed the use of platelet concentrates in patients with osteonecrosis.

Resumo O objetivo do estudo foi mapear, através de uma revisão de escopo, as evidências disponíveis na literatura sobre o uso de agregrantes plaquetários em pacientes comprometidos e que realizaram cirurgias odontológicas. Pesquisas foram realizadas em bases de dados por estudos clínicos com pacientes comprometidos que realizaram cirurgia odontológica e usaram agragantes plaquetários. Apenas estudos em inglês foram incluídos. Dois pesquisadores independentes realizaram a seleção dos estudos. Os seguintes dados foram extraídos: desenho do estudo, objetivo, procedimento cirúrgico, agregante plaquetário usado, envolvimento sistêmico, desfecho analisado e principais resultados. Uma análise descritiva dos dados foi realizada. Vinte e dois estudos preencheram os critérios de elegibilidade e foram incluídos. Série de casos foi o desenho de estudo mais frequente entre os estudos incluídos (41,0%). Em relação ao comprometimento sistêmico, 19 estudos reportaram pacientes com câncer e em relação ao tratamento cirúrgico, 16 estudos reportaram pacientes que realizavam tratamento para osteonecrose relacionada ao uso de medicamentos. O agregante mais utilizado foi o plasma rico em fribina (P-PRF). Em geral, maioria dos estudos recomendou o uso dos agregantes plaquetários. Assim, os resultados desse estudo sugerem que a evidência relacionada ao uso de agregantes plaquetários em pacientes comprometidos que realizam cirurgia odontológica é ainda inicial. Ainda, a maioria dos estudos avaliaram o uso de agregantes plaquetários em pacientes com osteonecrose.

Preemptive use of anti-inflammatories and analgesics in oral surgery: a review of systematic reviews.

Objectives: This review of systematic reviews evaluated the effectiveness and safety of the preemptive use of anti-inflammatory and analgesic drugs in the management of postoperative pain, edema, and trismus in oral surgery. Materials and methods: The databases searched included the Cochrane Library, MEDLINE, EMBASE, Epistemonikos, Scopus, Web of Science, and Virtual Health Library, up to March 2023. Pairs of reviewers independently selected the studies, extracted the data, and rated their methodological quality using the AMSTAR-2 tool. Results: All of the 19 studies reviewed had at least two critical methodological flaws. Third molar surgery was the most common procedure (n = 15) and the oral route the most frequent approach (n = 14). The use of betamethasone (10, 20, and 60 mg), dexamethasone (4 and 8 mg), methylprednisolone (16, 20, 40, 60, 80, and 125 mg), and prednisolone (10 and 20 mg) by different routes and likewise of celecoxib (200 mg), diclofenac (25, 30, 50, 75, and 100 mg), etoricoxib (120 mg), ibuprofen (400 and 600 mg), ketorolac (30 mg), meloxicam (7.5, 10, and 15 mg), nimesulide (100 mg), and rofecoxib (50 mg) administered by oral, intramuscular, and intravenous routes were found to reduce pain, edema, and trismus in patients undergoing third molar surgery. Data on adverse effects were poorly reported. Conclusion: Further randomized clinical trials should be conducted to confirm these findings, given the wide variety of drugs, doses, and routes of administration used.

Atypical traumatic bone cyst involving impacted lower third molar: report of case / Cisto ósseo traumático atípico envolvendo terceiro molar inferior impactado: relato de caso

ABSTRACT The traumatic bone cyst is an uncommon nonneoplastic lesion of the jaws that is considered as a "pseudocyst" because of the lack of an epithelial lining. This lesion is particularly asymptomatic and, therefore, is diagnosed by routine dental radiographic examination as a unilocular radiolucency with scalloped borders, mainly in the posterior mandibular region. The exact etiopathogenesis of the lesion remains uncertain, though it is often associated with trauma. The objective of this paper is to report one case of atypical traumatic bone cyst involving impacted lower third molar, addressing its clinical and radiographic characteristics, differential diagnosis, treatment through surgical exploration and case follow-up.

RESUMO O cisto ósseo traumático é uma lesão não neoplásica incomum dos maxilares, considerada um "pseudocisto" devido à ausência de um revestimento epitelial. Esta lesão é particularmente assintomática e, portanto, é diagnosticada pelo exame radiográfico odontológico de rotina como uma radioluscência unilocular com bordas recortadas, principalmente na região mandibular posterior. A etiopatogenia exata da lesão permanece incerta, embora esteja frequentemente associada a trauma. O objetivo deste trabalho é relatar um caso de cisto ósseo traumático atípico envolvendo terceiro molar inferior impactado abordando suas características clínicas, radiográficas, diagnóstico diferencial, tratamento por meio de exploração cirúrgica e proservação do caso.

Manejo del paciente anticoagulado en una cirugía dental / Management of the anticoagulated patient in dental surgery / Gerenciamento do paciente anticoagulado em cirurgia odontológica

Introducción: una adecuada hemostasia es crucial para el éxito del tratamiento odontológico invasivo, ya que los problemas de sangrado pueden dar lugar a complicaciones asociadas a una importante morbimortalidad. El tratamiento odontológico de pacientes que tienden a un mayor riesgo de sangrado debido al uso de fármacos anticoagulantes plantea un desafío en la práctica diaria de los profesionales de la odontología. El conocimiento adecuado de los mecanismos subyacentes a la hemostasia y el manejo optimizado de estos pacientes son, por lo tanto, cuestiones muy importantes. Se realiza un estudio de los fármacos anticoagulantes actualmente disponibles en el mercado, evaluando los riesgos y beneficios de suspender dicho fármaco previo a un tratamiento odontológico invasivo. Además, se hace una revisión de los protocolos de manejo actuales que se utilizan en estos pacientes. Material y métodos: se realizó una búsqueda bibliográfica en las bases de datos Epistemonikos y Medline/PubMed; en el portal Timbó y en la biblioteca virtual Scielo. Abarcando todos los estudios publicados en los últimos 15 años en inglés y español. Se encontraron 30 artículos, se seleccionaron 15 en primera instancia para finalizar con 11 artículos. En dicha selección el filtro fue que los demás artículos se referían a otros anticoagulantes que no eran parte de este trabajo. Resultados: se han desarrollado múltiples protocolos de manejo, aunque en todos los casos se requiere una historia clínica completa, junto con pruebas hemostáticas complementarias para minimizar los riesgos derivados del tratamiento odontológico. Discusión: muchos autores consideran que la medicación de los pacientes indicada para el tratamiento de una enfermedad de base no debe ser alterada o suspendida a menos que así lo indique el médico prescriptor. Se ha demostrado que las medidas hemostáticas locales son suficientes para controlar los posibles problemas de sangrado derivados del tratamiento dental.

Introduction: Adequate hemostasis is crucial for the success of invasive dental treatment, since bleeding problems can lead to complications associated with significant morbidity and mortality. The dental treatment of patients who are prone to an increased risk of bleeding due to the use of anticoagulant drugs poses a challenge in the daily practice of dental professionals. Adequate knowledge of the mechanisms underlying hemostasis and optimized management of these patients are therefore very important issues. A review is made of the anticoagulant drugs currently available on the market, evaluating the risks and benefits of suspending such a drug prior to invasive dental treatment. In addition, a review is made of the current management protocols used in these patients. Material and methods: A bibliographic search was carried out in the Epistemonikos and Medline/PubMed databases; in the Timbo portal and in the Scielo virtual library. All the studies published in the last 15 years in English and Spanish were included. Thirty articles were found, 15 were selected in the first instance to end up with 11 articles. In this selection, the filter was that the other articles referred to other anticoagulants that were not part of this work. Results: multiple management protocols have been developed, although in all cases a complete clinical history is required, together with complementary hemostatic tests to minimize the risks derived from dental treatment. Discussion: many authors consider that the patient's medication indicated for the treatment of an underlying disease should not be altered or suspended unless so indicated by the prescribing physician. It has been shown that local hemostatic measures are sufficient to control possible bleeding problems derived from dental treatment.

Introdução: A hemostasia adequada é crucial para o sucesso do tratamento dentário invasivo, pois problemas de sangramento podem levar a complicações associadas a uma morbidade e mortalidade significativas. O tratamento odontológico de pacientes que são propensos a um risco maior de sangramento devido ao uso de drogas anticoagulantes representa um desafio na prática diária dos profissionais da odontologia. O conhecimento adequado dos mecanismos subjacentes à hemostasia e o gerenciamento otimizado desses pacientes são, portanto, questões muito importantes. É realizada uma revisão dos anticoagulantes atualmente disponíveis no mercado, avaliando os riscos e benefícios de descontinuar tal medicamento antes do tratamento dentário invasivo. Além disso, é feita uma revisão dos protocolos de gerenciamento atuais usados nesses pacientes. Material e métodos: Foi realizada uma pesquisa bibliográfica nas bases de dados Epistemonikos e Medline/PubMed; no portal Timbo e na biblioteca virtual Scielo. Todos os estudos publicados nos últimos 15 anos, em inglês e espanhol, foram incluídos. Trinta artigos foram encontrados, 15 foram selecionados em primeira instância para acabar com 11 artigos. Nesta seleção, o filtro foi que os outros artigos se referiam a outros anticoagulantes que não faziam parte deste trabalho. Resultados: foram desenvolvidos múltiplos protocolos de gerenciamento, embora em todos os casos seja necessário um histórico clínico completo, juntamente com testes hemostáticos complementares para minimizar os riscos derivados do tratamento odontológico. Discussão: muitos autores consideram que a medicação os pacientes indicada para o tratamento de uma doença subjacente não deve ser alterada ou descontinuada, a menos que o médico que a prescreve dê instruções nesse sentido. Medidas hemostáticas locais demonstraram ser suficientes para controlar potenciais problemas de sangramento resultantes do tratamento odontológico.

Drogas antiagregantes plaquetárias e anticoagulantes em pacientes que se submeterão à cirurgia oral: conduta / Antiagregant platelet and anticoagulant drugs in patients who will submit oral surgery: conduct

Objetivo: Como a frequência de pacientes em uso de anticoagulantes e antiagragantes plaquetários nos consultórios odontológicos é crescente, este trabalho objetivou avaliar através de Revisão de Literatura, qual o melhor manejo desses medicamentos na prática odontológica perioperatória. Metodologia: Trata-se de uma revisão integrativa da literatura, utilizadas as bases de dados Scielo e PubMed. Foram escolhidos os seguintes descritores disponíveis na BVs e PubMed em inglês "Platelet Aggregation Inhibitors", "Oral Surgical Procedures" e "Antigoagulants" no período de 2016 a 2021. Também foram consultados livros e sites de diretrizes do Governo. Foram escolhidos 20 artigos para elaboração da pesquisa. Resultados: doenças cardiovasculares e outras condições clínicas pró-coagulantes tem prevalência crescente e são conhecidos fatores de risco para a ocorrência de fenômenos tromboembólicos graves. A terapia antitrombótica tem papel definido nesses casos. No perioperatorio de cirurgias orais, a decisão por suspender ou manter a terapia deve ser individualizada e pode ser orientada por guidelines. Conclusão: procedimentos orais de baixo risco de sangramento podem ser conduzidos sem a descontinuação da terapia antitrombótica. Cirurgias de moderado a alto risco frequentemente requerem suspensão temporária das medicações para fins de minimizar os riscos de complicações hemorrágicas... (AU)

Objective: As the frequency of patients using anticoagulants and antiplatelet agents in dental offices is increasing, this study aimed to evaluate, through a Literature Review, which is the best management of these medications in dental perioperative practice. Methodology: This is an integrative literature review, being used Scielo and PubMed databases. The following descriptors available in BVs and PubMed "Platelet aggregation inhibitors", "Oral Surgical Procedures" and "Antigoagulants" were used, from 2016 to 2021. In addition, the search was also performed in guideline books and Government websites. Twenty articles were chosen for research elaboration. Results: established cardiovascular disease and other procoagulant clinical conditions have an increasing prevalence, especially among the elderly, and are known risk factors for the occurrence of severe thromboembolic phenomena. Antithrombotic therapy has defined role in these cases. In the perioperative period of oral surgery, the decision to suspend or maintain therapy must be individualized and may be guided by guidelines. Age appears as a clinical criterion in the main ones used. Conclusion: oral procedures with low risk of bleeding can be carried out without discontinuing antithrombotic therapy. Moderate to high-risk surgeries usually require its temporary suspension in order to minimize the risk of bleeding complications... (AU)

Queiloplastia de Castañón: una técnica viable y efectiva en la reconstrucción parcial del labio inferior / Castañón Cheiloplasty: a viable and effective technique in the partial reconstruction lower lip

Introducción: Para el tratamiento del carcinoma epidermoide labial existen varias modalidades terapéuticas, pero la cirugía constituye la primera elección. Numerosas técnicas han sido descritas para el manejo de lesiones que afectan más de un tercio del labio inferior. Sin embargo, la selección de alguna en particular depende del cumplimiento de los principios reconstructivos de esta unidad. Objetivo: Ejemplificar los beneficios de la utilización de la queiloplastia de Castañón, para la reconstrucción labial parcial, en un paciente con carcinoma epidermoide de labio inferior. Presentación de caso: Se presenta un paciente masculino de 68 años de edad, con antecedentes de hábito de fumar y alcoholismo, que acudió a consulta de Cirugía Oncológica de Cabeza y Cuello por presentar lesión localizada en bermellón de labio inferior. Se realizó biopsia, mediante incisión, que informó un carcinoma epidermoide moderadamente diferenciado. Se estudió como un T2N0M0, etapa II y se trató quirúrgicamente mediante queilectomía subtotal y reconstrucción con técnica de Castañón. Conclusiones: Se presentó el caso clínico de un paciente con carcinoma epidermoide de labio inferior, entidad patológica de alta incidencia. La cirugía constituyó la única modalidad de tratamiento utilizada. Una vez realizada la resección quirúrgica de la lesión, se reconstruyó el defecto, para lo que se utilizó la queiloplastia descrita por Castañón, opción útil para lograr el cumplimiento de los principios estéticos y funcionales(AU)

Introduction: For the treatment of labial squamous cell carcinoma there are several therapeutic modalities, but surgery is the first choice. Numerous techniques have been described for the management of lesions affecting more than a third of the lower lip. However, the selection of any particular one depends on the fulfillment of the reconstructive principles of this unit. Objective: Exemplify the benefits of using Castañón cheiloplasty for partial lip reconstruction in a patient with squamous cell carcinoma of the lower lip. Case presentation: A 68-year-old male patient with a history of smoking and alcoholism was presented, who went to the Head and Neck Oncological Surgery consultation for presenting a lesion located in vermilion of the lower lip. An incisional biopsy reported moderately differentiated squamous cell carcinoma. It was studied as a T2N0M0, stage II and was treated surgically by subtotal cheilectomy and reconstruction with Castañón technique. Conclusions: The clinical case of a patient with squamous cell carcinoma of the lower lip, a pathological entity of high incidence, was presented. Surgery was the only treatment modality used. Once the surgical resection of the lesion was performed, the defect was reconstructed, for which the cheiloplasty described by Castañón was used, a useful option to achieve compliance with the aesthetic and functional principles(AU)

High-power laser for oral excisional biopsy in an oncologic patient with pancytopenia.

Oral surgical procedures are a great challenge in cancer patients, especially those with pancytopenia, given the risk of both hemorrhage and opportunistic infection. Thus, we report herein a case of a patient with refractory acute myeloid leukemia, severe pancytopenia, and some episodes of febrile neutropenia, who presented asymptomatic, bilateral lesions on the tongue, requiring excisional biopsy. Considering the high risk of bleeding, surgical intervention was proposed with a high-power laser (HPL) at the bedside. There was no considerable bleeding and stitches were not needed. Within 48 h postoperatively, the patient reported neither pain nor further bleeding and her tongue presented normal function. The patient was under a follow-up period of about 8 months, with no lesion relapse. The HPL seems to be of great value for preventing excessive bleeding and late infection in patients with pancytopenia submitted to minor oral surgeries.

A Novel Simplified Workflow for Guided Endodontic Surgery in Mandibular Molars With a Thick Buccal Bone Plate: A Case Report.

One of the challenges in apical surgery in mandibular molars is the thick buccal cortical bone plate, which might lead to access errors, damage to neighboring teeth, and injury to healthy tissue. Surgical guide templates with 3-dimensional (3D) impressions have been suggested for use in such cases, allowing greater precision. Usually, this technique involves a cone-beam computed tomography (CBCT) examination related to a 3D oral scanning to generate surgical templates printed from 3D imaging data. This study reports a novel workflow possibility in which apical surgery is performed with the aid of a surgical guide planned only with CBCT, excluding the need for 3D oral scanning. A 32-year-old woman presented with asymptomatic apical periodontitis and external root resorption on the mesial root of tooth #19. A surgical template was planned using only the patient's CBCT scan to provide precise access to the lesion and remove a mandibular cortical bone block. The procedure was carried out with apicoectomy, root-end preparation, and retrograde filling, and the bone block was repositioned before suture. No postoperative complications were reported. After 1 year, the patient presented asymptomatic, and a CBCT scan confirmed bone healing. The current 3D-printed guides may be planned and printed through a novel simplified workflow with a CBCT scan only, which allows its application in apical surgery for precise apex and surgical site location.

Defecto oncológico maxilar reconstruido mediante colgajo de músculo temporal / Maxillary oncologic defect reconstructed with temporal muscle flap / Defeito oncológico maxilar reconstruído por aba muscular temporal

El macizo facial es una región anatómica compleja que alberga órganos sensoriales. El desarrollo de una enfermedad oncológica, así como su tratamiento, causan defectos funcionales y estéticos con un alto costo físico y psíquico para el paciente y su entorno. Es por ello que la reconstrucción representa un reto. Las diferentes posibilidades incluyen prótesis obturatríces, colgajos libres, pediculados o microvascularizados. En este artículo se describirá el colgajo de músculo temporal y se desarrolla un caso clínico de cirugía oncológica maxilar reconstruido mediante éste en un paciente que presenta una lesión exofítica en cuadrante superior derecho, que se extiende sobre el flanco vestibular, reborde alveolar y zona palatina, desde zona de premolares hasta la zona del segundo molar inclusive, impidiéndole usar la prótesis dental. Esta cirugía es una técnica económica, que requiere menor tiempo quirúrgico que otras técnicas, asociándose a poco porcentaje de fracaso y pocas complicaciones post operatorias.

The facial mass is a complex anatomical region that houses sensory organs. The development of an oncologic disease, as well as its treatment, causes functional and esthetic defects with a high physical and psychological cost for the patient and his environment. This is why reconstruction represents a challenge. The different possibilities include obturator-root prostheses, free, pedicled or microvascularized flaps. In this article the temporal muscle flap will be described and a clinical case of maxillary oncologic surgery reconstructed by means of it is developed in a patient who presents an exophytic lesion in the right upper quadrant, which extends over the vestibular flank, alveolar ridge and palatal area, from the premolar area up to and including the second molar area, preventing him from using the dental prosthesis. This surgery is an economical technique that requires less surgical time than other techniques, and is ass

A massa facial é uma região anatômica complexa que abriga órgãos sensoriais. O desenvolvimento de uma doença oncológica, assim como seu tratamento, causa defeitos funcionais e estéticos com alto custo físico e psicológico para o paciente e seu ambiente. A reconstrução é, portanto, um desafio. As diferentes possibilidades incluem as próteses de raiz obturadora, abas livres, pediculadas ou microvascularizadas. Este artigo descreve o retalho muscular temporal e descreve um caso clínico de cirurgia oncológica maxilar reconstruída utilizando-o em um paciente com lesão exofítica no quadrante superior direito, estendendo-se pelo flanco vestibular, rebordo alveolar e área palatina, desde a área do pré-molar até a área do segundo molar inclusive, impedindo-o de utilizar a prótese dentária. Esta cirurgia é uma técnica econômica, que requer menos tempo cirúrgico que outras.
