Restauração transcirúrgica: passo a passo / Transsurgical restoration: step by step

Sabe-se que para uma restauração ser considerada um sucesso clínico é preciso que haja uma concomitância saudável entre a estrutura dentária, o material restaurador e as estruturas biológicas periodontais. As restaurações transcirúrgicas caracterizam-se como procedimentos alternativos para possibilitar a restauração de dentes com cárie dentária extensa, restaurações subgengivais desadaptadas e fraturas. O presente estudo teve como objetivo realizar um relato de caso de um procedimento cirúrgico-restaurador, através de uma técnica de restauração transcirúrgica. Este estudo tem como justificativa relatar um caso clínico, colaborando com maiores informações sobre a escolha da técnica a ser empregada, mostrando em quais situações devemos escolher uma restauração transcirúrgica e quais seus benefícios. Também, salientar se devemos fazer a recuperação do espaço biológico do periodonto ou não(AU)

It is known that for a restoration to be considered a clinical success, there must be a healthy concomitance between the tooth structure, the restorative material and the periodontal biological structures. Transsurgical restorations are characterized as alternative procedures to enable the restoration of teeth with extensive dental caries, maladapted subgingival restorations and fractures. The present study aims to carry out a case report of a surgical-restorative procedure, using a transsurgical restoration technique. This study is justified by reporting a clinical case, providing more information on the choice of technique to be used, showing in which situations we should choose a transsurgical restoration and what its benefits are. Also, highlight whether we should recover the biological space of the periodontium or not(AU)

Tratamento integrado para correção do sorriso gengival: relato de caso / Integrated treatment for correction of gingival smile: case report

O sorriso gengival possui inúmeras causas, podendo acontecer por motivos esqueléticos, musculares ou por alteração no desenvolvimento dos tecidos de suporte. No entanto, na atualidade, a estética vermelha e a branca têm se apresentado completamente passíveis de transformações e com uma gama de procedimentos cirúrgicos ou não cirúrgicos para sanar as queixas dos pacientes. O objetivo geral deste trabalho é mostrar o poder que a odontologia tem frente às questões estéticas, como, por exemplo, a vergonha de sorrir por não se sentir confortável com os dentes curtos e com uma grande faixa de gengiva sendo exposta. O método utilizado foi um relato de caso. Que descreve todos os passos clínicos do tratamento de um paciente de 40 anos, que estava insatisfeita com o seu sorriso por apresentar erupção passiva alterada juntamente com hiperatividade do lábio superior. O plano de tratamento escolhido foi de realizar a cirurgia de aumento de coroa clínica estético, seguido de clareamento dentário e posteriormente um reposicionamento labial, com ajuda da toxina botulínica. Finalizando, para ajudar na cicatrização, o uso de laserterapia. O resultado de todo o processo cirúrgico envolvido neste trabalho, é satisfação do paciente, materializando o sonho deste, devolvendo segurança e espontaneidade ao sorrir. Pôde-se observar que através da combinação de técnicas cirúrgicas periodontais para tratar o sorriso gengival, obtém-se êxito tanto no sentido científico quanto no biológico, alcançando um sorriso esteticamente mais atrativo(AU)

Gummy smile has numerous causes, which can occur for skeletal or muscular reasons or due to changes in the development of supporting tissues. However, nowadays, the red and white aesthetics have been completely capable of transformation and with a range of surgical or non-surgical procedures to resolve patients' complaints. The general objective of this work is to show the power that dentistry has in the face of aesthetic issues, such as, for example, the shame of smiling due to not feeling comfortable with short teeth and a large strip of gum being exposed. The method used was a case report. Which describes all the clinical steps of the treatment of a 40-year-old patient, who was dissatisfied with her smile due to an altered passive eruption together with hyperactivity of the upper lip. The chosen treatment plan was to perform aesthetic clinical crown augmentation surgery, followed by tooth whitening and later lip repositioning, with the help of botulinum toxin. Finally, to help with healing, the use of laser therapy. The result of the entire surgical process involved in this work is patient satisfaction, materializing the patient's dream, restoring security and spontaneity when smiling. It was observed that through the combination of periodontal surgical techniques to treat gummy smile, success is achieved both in the scientific and biological sense, achieving a more aesthetically attractive smile(AU)

Introduction: The treatment of malignant or benign tumors can result in surgical procedures, such as partial or total maxillectomy, generating oral communication in patients. One way to resolve these maxillofacial changes is through rehabilitative treatment with obturator prostheses in order to reestablish masticatory, aesthetic, phonetic and psychological function. Objective: the objective of this work was to report the clinical case of a cancer patient who was rehabilitated with an obturator prosthesis due to maxillectomy for malignant neoplasia of the maxillary sinus. Case report: A 62-year-old male patient sought dental care at the Oral Oncology Center of the Universidade Estadual Paulista "Júlio de Mesquita Filho" (UNESP) in Araçatuba ­ SP after undergoing a partial maxillectomy with oral cavity and was referred for the Specialization Course in Dental Prosthesis at the Faculty of Dentistry ­ Unesp/Araçatuba-SP for rehabilitation. It was proposed, firstly, to create an obturator prosthesis to close the bucosinusal communication and a total lower prosthesis for the antagonistic arch and, later, to create a facial prosthesis. Conclusion: Rehabilitative treatment with obturator prostheses has a good aesthetic and functional result, favoring better chewing and phonetic function, and considerably improving the psychological condition that is greatly affected in patients undergoing total or partial maxillectomy, requiring good interaction with the entire the multidisciplinary team involved so that there is better integrated treatment for rehabilitation and improved quality of life

Tratamento do sorriso gengival por meio da cirurgia periodontal: relato de caso / Treatment of gummy smile through periodontal surgery: case report

A busca por um sorriso considerado perfeito tem sido cada vez maior e isso tem se tornado um desafio para o Cirurgião-Dentista, visto que um sorriso harmônico não envolve somente dentes, mas também gengiva. A exposição excessiva da gengiva ao sorrir ou falar é considerada uma característica antiestética, pois gera uma desarmonia entre dentes, gengiva e lábios. Quando o paciente expõe 3 milímetros ou mais de gengiva ao sorrir, chamamos essa exposição de Sorriso Gengival. O presente trabalho tem como objetivo relatar o tratamento de um caso de sorriso gengival, onde foi realizada cirurgia periodontal ressectiva a fim de diminuir a exposição de tecido gengival ao sorrir. Descrição do caso: Paciente adulto 21 anos, sexo masculino, procurou atendimento no curso de graduação em Odontologia do Centro Universitário da Serra Gaúcha ­ FSG, com queixa de insatisfação estética devido ao tamanho de seus dentes e mostrar muito tecido Gengival ao sorrir. Após anamnese, exame clínico e radiográfico, o paciente foi diagnosticado com Sorriso gengival. O plano de tratamento proposto foi de cirurgia periodontal ressectiva. Conclusão: A partir do exposto, podemos concluir que o tratamento do sorriso gengival depende de sua etiologia. Um correto diagnóstico é de extrema importância, pois dependendo do fator etiológico do sorriso gengival, o plano de tratamento pode ser elaborado de acordo com a necessidade do paciente. No caso apresentado, o procedimento escolhido, cirurgia periodontal ressectiva, se mostrou efetivo no tratamento do sorriso gengival, devolvendo estética e satisfação ao paciente(AU)

The search for a smile that is considered perfect has been increasing and this has become a challenge for the Dental Surgeon, since a harmonious smile does not only involve teeth, but also gums. Excessive exposure of the gums when smiling or talking is considered an unsightly feature, as it creates disharmony between teeth, gums and lips. When the patient exposes 3 millimeters or more of gum when smiling, we call this exposure Gummy Smile. The present work aims to report the treatment of a case of gummy smile, where resective periodontal surgery was performed in order to reduce the exposure of gingival tissue when smiling. Case description: A 21-year-old adult patient, male, sought care at the undergraduate course in dentistry at the Centro Universitário da Serra Gaúcha ­ FSG, complaining of aesthetic dissatisfaction due to the size of his teeth and showing a lot of gingival tissue when smiling. After anamnesis, clinical and radiographic examination, the patient was diagnosed with gummy smile. The proposed treatment plan was resective periodontal surgery. Conclusion: From the above, we can conclude that the treatment of gummy smile depends on its etiology. A correct diagnosis is extremely important, because depending on the etiological factor of the gummy smile, the treatment plan can be elaborated according to the patient's needs. In the case presented, the chosen procedure, resective periodontal surgery, proved to be effective in the treatment of gummy smile, restoring aesthetics and patient satisfaction(AU)

Preservação óssea alveolar pós exodontia: objetivos, opções técnicas, vantagens e desvantagens / Alveolar bone preservation after tooth extraction: objectives, technical options, advantages and disadvantages

A extração do elemento dentário promove uma série de eventos biológicos que resultam no colapso da estrutura alveolar, ocasionando a perda óssea volumétrica na região de extração. Preservar esse alvéolo dentário é imprescindível para uma boa reabilitação dentária do paciente. Objetivo: Realizar uma revisão de literatura abordando os objetivos, opções técnicas, vantagens e desvantagens da preservação óssea alveolar pós extração. Materiais e métodos: Foi feita uma revisão de literatura utilizando as bases de dados Biblioteca Virtual em Saúde (BVS), PubMed e Google acadêmico, usando os descritores "extração dentária", "perda do osso alveolar", "regeneração óssea". Foram incluídos 34 artigos. Resultados: A preservação alveolar pós extração começa desde a realização de uma técnica cirúrgica menos invasiva até a colocação de enxertos do tipo autógenos, alógenos, xenógenos, aloplásticos e biomateriais promotores de cicatrização e reparação tecidual. Conclusão: Existe na literatura atual uma vasta gama de textos científicos que abordam técnicas de preservação alveolar pós exodontia, com distintas respostas teciduais. Todavia, nenhum biomaterial listado nesta revisão contém todas as características que proporcionam regeneração completa do osso alveolar após exodontia(AU)

The extraction of the dental element promotes a series of biological events that results in the collapse of the alveolar structure, causing volumetric bone loss in the region of extraction. Preserving this dental alveolus is essential for a good dental rehabilitation of the patient. Objective: To conduct a literature review addressing the objectives, technical options, advantages and disadvantages of post-extraction alveolar bone preservation. Materials and methods: A literature review was carried out using the Virtual Health Library (VHL), PubMed and academic Google databases, using the descriptors "tooth extraction", "alveolar bone loss", "bone regeneration". 34 articles were included. Results: Post-extraction alveolar preservation starts from the performance of a less invasive surgical technique to the placement of autogenous, allogeneic, xenogeneic, alloplastic and biomaterials that promote healing and tissue repair. Conclusion: There´s is a wide range of scientific texts in the current literature that address post-extraction alveolar preservation techniques with different tissue responses. However, none of the biomaterials listed in this review contain all the characteristics that provide complete regeneration of alveolar bone after extraction(AU)

Actualización de la Epidemiología de Tratamientos Quirúrgicos Maxilofaciales en Hospital Público de Santiago de Chile: Estudio Comparativo - Retrospectivo de 4 Años / Epidemiological Update of Maxillofacial Surgical Treatments in a Public Hospital in Santiago de Chile: A Comparative Retrospective Study of 4 Years

La cirugía maxilofacial es una especialidad médico quirúrgica que se encarga tanto del diagnóstico como del tratamiento de enfermedades que afecta al territorio craneofacial. En Chile existen pocos estudios epidemiológicos en cirugía maxilofacial que describan con detalle el tipo de intervenciones realizadas más allá del trauma maxilofacial, y que además involucren el período por pandemia COVID-19. El objetivo del estudio fue actualizar la epidemiología de resolución quirúrgica bajo anestesia general en el Hospital San José de Santiago de Chile entre los años 2018 y 2021 y compararlo con el estudio realizado en mismo recinto entre los años 2007 y 2013. Se realizó un estudio retrospectivo con 607 pacientes. Se recopiló información de acuerdo a edad, género del paciente y tipo de intervención. Del total de intervenciones realizadas, 176 (29%) correspondieron a trauma maxilofacial y 431 (71%) a cirugías de etiología no traumática. Edad promedio de 38,7 años. Proporción entre el sexo masculino y femenino de 1,28:1. La fractura más frecuente fue la mandibular (59,66%), seguida de la orbito cigomática (23,86%) y la panfacial (4,55%). En las cirugías de etiología no traumática predominaron las intervenciones por dismorfosis dentofaciales (23,2%), seguido tumores de los maxilares (20,41%), lesiones orales (18,56%), defocaciones dentarias (16,24%), infecciones (8,81%), patologías de articulación temporomandibular (8,35%) y finalmente retiro de material de osteosíntesis (4.41%). Las intervenciones de etiología no traumática y la resolución de fracturas mandibulares fueron los procedimientos más realizados por la unidad. El conocimiento de estos datos y la comparación con el estudio anterior permite observar el cambio en la epidemiologia, que puede explicarse por la pandemia por COVID-19. Considerando lo anterior, ambos tipos de intervenciones deben ser abordadas de manera integral y con las condiciones adecuadas. Para ello es importante enfocar los recursos en esas áreas y desarrollar mayor entrenamiento en las mismas.

Maxillofacial surgery is a medical- surgical specialty that deals with both diagnosis and treatment of diseases affecting the craniofacial territory. In Chile there are few epidemiological studies in maxillofacial surgery that describe in detail the type of interventions performed beyond maxillofacial trauma, and that also involve the COVID-19 pandemic period. The aim of the study was to update the epidemiology of surgical resolution under general anesthesia at the Hospital San José in Santiago de Chile between 2018 and 2021 and to compare it with the study performed at the same hospital between 2007 and 2013. A retrospective study was performed with 607 patients. Information was collected according to age, patient gender and type of intervention. Of the total number of interventions performed, 176 (29%) corresponded to maxillofacial trauma and 431 (71%) to surgeries of non-traumatic etiology. Average age of 38.7 years. Male to female sex ratio of 1.28:1. The most frequent fracture was mandibular (59.66%), followed by orbito-zygomatic (23.86%) and panfacial (4.55%). In surgeries of non-traumatic etiology, interventions for dentofacial dysmorphosis predominated (23.2%), followed by tumors of the jaws (20.41%), oral lesions (18.56%), dental defocations (16.24%), infections (8.81%), temporomandibular joint pathologies (8.35%) and finally removal of osteosynthesis material (4.41%). Interventions of non-traumatic etiology and resolution of mandibular fractures were the procedures most performed by the unit. The knowledge of these data and the comparison with the previous study allows us to observe the change in epidemiology, which can be explained by the COVID-19 pandemic. Considering the above, both types of interventions should be approached in a comprehensive manner and with the appropriate conditions. To this end, it is important to focus resources in these areas and to develop more training in them.

Rehabilitación implanto protésica en paciente con injerto mandibular de larga data / Implant-prosthetic rehabilitation in a patient with a longstanding mandibular graft / Reabilitação protética com implantes em pacientes com enxerto mandibular de longa data

En la actualidad es cada vez más frecuente la consulta de pacientes que siendo sometidos en edades tempranas a cirugías de extirpación tumoral y posterior reconstrucción con injertos presentan problemas tanto funcionales como estéticos, el uso de prótesis implantosoportadas mejora la calidad de vida, pero al mismo tiempo representan un desafío por la baja disponibilidad ósea. Se presenta un caso clínico de rehabilitación protésica implantosoportada en una paciente con gran déficit óseo mandibular como consecuencia de le extirpación de una neoplasia y posterior injerto de costilla. Se colocaron 2 implantes osteointegrados en hueso remanente y rehabilitación con prótesis removible sostenida a una barra colada. Por ser un tratamiento poco invasivo y conservador fue aceptado fácilmente por la paciente y la mejora tanto en la estética como en la función fue notoria.

Nowadays, it is becoming more and more frequent to see patients who underwent surgery for tumor removal and subsequent reconstruction with grafts at an early age, presenting both functional and esthetic problems. The use of implant-supported prostheses improves the quality of life, but at the same time represents a challenge due to the low availability of bone. A clinical case of implant-supported prosthetic rehabilitation is presented in a patient with a great mandibular bone deficit as a consequence of the removal of a neoplasm and subsequent rib graft. Two osseointegrated implants were placed in the remaining bone and rehabilitation with a removable prosthesis supported by a cast bar. Being a minimally invasive and conservative treatment, it was easily accepted by the patient and the improvement in both esthetics and function was notorious.

Atualmente, são cada vez mais frequentes os pacientes submetidos à cirurgia de remoção de tumores e posterior reconstrução com enxertos em idade precoce que apresentam problemas funcionais e estéticos. O uso de próteses implanto-suportadas melhora a qualidade de vida, mas, ao mesmo tempo, representa um desafio devido à baixa disponibilidade de osso. Apresentamos um caso clínico de reabilitação protética implanto-suportada em um paciente com grande déficit ósseo mandibular em consequência da remoção de uma neoplasia e posterior enxerto de costela. Dois implantes osseointegrados foram colocados no osso remanescente e a reabilitação foi feita com uma prótese removível suportada por uma barra de gesso. Por se tratar de um tratamento minimamente invasivo e conservador, foi facilmente aceito pelo paciente e a melhora na estética e na função foi perceptível.

Tercer molar heterotópico, etiología y manejo quirúrgico / Heterotopic third molar, etiology and surgical management

Los terceros molares heterotópicos son dientes que se encuentran incluidos en los maxilares y la mandíbula distantes a su sitio de erupción habitual. Su etiología no está bien definida y existen diversas teorías. Estos dientes pueden aparecer en diferentes zonas de las estructuras óseas, teniendo predilección por la mandíbula. Suelen aparecer entre la segunda y la séptima década de la vida, la mayoría de los casos son hallazgos imagenológicos en la consulta odontológica. El tercer molar mandibular es el diente que presenta heterotopía con mayor frecuencia, siendo su localización habitual en rama mandibular y en la región subcondílea. El quiste dentígero es la patología asociada más común. Presentamos un caso de tercer molar heterotópico en rama mandibular derecha de larga evolución, relacionado a un quiste dentígero, el cual se manejó bajo anestesia regional. Se describe la etiología, técnica quirúrgica y consideraciones especiales relacionados con los dientes heterotópicos (AU)

Heterotopic third molars are teeth that are embedded in the maxilla and mandible, remote from their usual eruption site. Its etiology is not well defined and there are various theories at the moment. These teeth can appear in different areas of the bone's structures, having a predilection for the jaw. They usually appear between the second and seventh decade of life, and in most cases are imaging findings. The mandibular third molar is the tooth with the most frequent heterotopia, being its usual location in the mandibular branch and in the subcondylar region. The dentigerous cyst is the most common associated pathology. We present a case of a long evolution heterotopic third molar in the right mandibular branch, related to a dentigerous cyst which was managed under local anesthesia. The etiology, surgical technique and special considerations related to heterotopic teeth are described (AU)

Surgical Treatment of Oral Fibrous Hyperplasia with Diode Laser: An Integrative Review / Tratamiento Quirúrgico de la Hiperplasia Fibrosa Oral con Láser de Diodo: Una Revisión Integradora

This study aimed to carry out an integrative review of the use of diode lasers in the treatment of oral fibrous hyperplasia in order to observe surgical efficacy, healing process, and main microscopic findings. The following databases-PubMed/MEDLINE, Embase, Virtual Health Library, Scopus, Web of Science, and gray literature-were searched without regard to the time of year or language. Diode laser treatment cases described in case reports and case series were included, but those who did not undergo microscopic analysis to confirm the diagnosis or who did not provide postoperative information were excluded. Twelve studies (64 patients) were included. Prevalence was observed for females (68.75 %, n=44). In view of the diagnosis, there was a prevalence of focal fibrous hyperplasia (79.68 %, n=51), followed by inflammatory fibrous hyperplasia (20.31 %, n=13). For surgical removal, a diode laser was used with a wavelength ranging from 808 to 960 nm, in continuous mode, and an average power of 2830 mW. In general, there were no intercurrences in the trans and postoperative periods and wound healing occurred by second intention, with excellent evolution. High-powered diode lasers can be an excellent therapeutic option for oral hyperplastic lesions. Long-term clinical trials should be conducted to determine laser setting parameters in various oral lesions.

El objetivo de este estudio fue realizar una revisión integradora sobre el uso del láser de diodo en el tratamiento de la hiperplasia fibrosa oral, con el fin de visualizar la eficacia quirúrgica, el patrón de cicatrización y el análisis de los principales resultados microscópicos. Se realizó una búsqueda sin restricciones de año e idioma en PubMed/MEDLINE, Embase, Virtual Health Library, Scopus, Web of Science y literatura gris. Se incluyeron reportes de casos y series de casos que brindaron información sobre pacientes diagnosticados con lesiones hiperplásicas orales tratados con láser de diodo, excluyendo aquellos a los que no se les había realizado análisis microscópico para confirmar el diagnóstico, así como aquellos que no brindaron información postoperatoria. Se incluyeron doce estudios (64 pacientes). Se observó prevalencia en el sexo femenino (68,75 %, n=44). Ante el diagnóstico, predominó la hyperplasia fibrosa focal (79,68 %, n=51), seguida de la hiperplasia fibrosa inflamatoria (20,31 %, n=13). Para la remoción quirúrgica se utilizó un láser de diodo con una longitud de onda de 808 a 960 nm, en modo continuo, y una potencia promedio de 2830 mW. En general, no hubo intercurrencias en el trans y postoperatorio y la cicatrización de la herida ocurrió por segunda intención, con excelente evolución. El uso de láseres de diodo de alta potencia puede ser una excelente alternativa terapéutica para las lesiones hiperplásicas orales. Se deben realizar más estudios clínicos a largo plazo para determinar los parámetros de ajuste del láser en diferentes lesiones orales.

Complicaciones Asociadas a la Remoción Estética del Cuerpo Adiposo de la Boca (de Bichat) - Revisión Narrativa / Complications Associated with Aesthetic Removal of the Buccal Adipose Body (Bichat's fat-pad) - Narrative Review

El cuerpo adiposo de la boca (CAB) es un componente adiposo multilobulado bien delimitado, localizado de manera bilateral en la región facial íntimamente relacionado a estructuras nerviosas y vasculares. La remoción de CAB es un procedimiento ampliamente estudiado en el campo de la cirugía maxilofacial, utilizado principalmente para cubrir defectos. Su influencia en la estética facial ha iniciado una popularización de la remoción de la extensión bucal de CAB para obtener un rostro más estilizado, intervención difundida como poco invasiva y sin complicaciones. El objetivo de este estudio fue recopilar y evaluar estudios que reporten y evalúen complicaciones asociadas a la remoción por razones estéticas de CAB. Se revisó la evidencia en las bases de datos Medline vía PubMed, Epistemonikos, Scopus y Google Scholar, utilizando términos predefinidos, seleccionando estudios primarios de reportes de casos. Se incluyeron 7 artículos con un total de 10 pacientes; de estos, ocho pacientes se realizaron este procedimiento en Brasil, uno en Estados Unidos y uno en Chile. La distribución de la población fue de 3:7 entre hombres y mujeres con edad promedio de 35 años y un rango entre los 23 a los 49 años. En relación a las complicaciones reportadas, 100 % de los pacientes presentaron asimetría facial, un 80 % presentó edema facial, 30 % manifestaron sialocele, Trismus 20 %, 40 % presentó hematoma, 20 % compromiso del estado general, 20 % presentaron disfagia, en los casos de hipoestesia, parestesia, absceso, seroma, parálisis facial, odinofagia, fiebre se expresaron en 10 % de la población estudiada. En todos los estudios se describió una reintervención quirúrgica posterior a la remoción estética del cuerpo adiposo de bichat. La escasa literatura y la baja calidad de esta, no permite estimar el porcentaje real de posibles complicaciones, tampoco es posible determinar sus resultados a largo plazo ya que no existe en la evidencia un seguimiento apropiado para estos pacientes.

The buccal adipose body (BAB) is a well- defined multilobulated adipose component, located bilaterally in the facial region, closely related to nervous and vascular structures. BAB removal is a widely studied procedure in the field of maxillofacial surgery, used mainly to cover defects. Its influence on facial aesthetics has started to popularize the removal of the BAB buccal extension to obtain a more stylized face, an intervention widely known as minimally invasive and without complications. The objective of this study was to collect and evaluate studies that report and evaluate complications associated with the removal of BAB for cosmetic reasons. The evidence was reviewed in the Medline databases via PubMed, Epistemonikos, Scopus, and Google Scholar, using predefined terms, selecting primary studies from case reports. 7 articles with a total of 10 patients were included; Of these, eight patients underwent this procedure in Brazil, one in the United States, and one in Chile. The distribution of the population was 3:7 between men and women with an average age of 35 years and a range between 23 to 49 years. In relation to the reported complications, 100 % of the patients presented facial asymmetry, 80 % presented facial edema, 30 % manifested sialocele, trismus 20 %, 40 % presented hematoma, 20 % compromised general state, 20 % presented dysphagia, in the cases of hypoesthesia, paresthesia, abscess, seroma, facial paralysis, odynophagia, fever were expressed in 10 % of the studied population. All the studies described a surgical reintervention after cosmetic removal of the bichat adipose body. The scarce literature and its low quality do not allow estimating the real percentage of possible complications, nor is it possible to determine their long-term results since there is no evidence of appropriate follow-up for these patients.

Parestesia do nervo alveolar inferior decorrente de procedimentos cirúrgicos e suas formas de tratamentos / Paresthesi of the lower alveolar nerve resulting from surgical procedures and its forms of treatment

Nas cirurgias odontológicas é possível que ocorra alguns acidentes ou complicações que podem interferir no dia a dia do paciente. A lesão do nervo alveolar inferior é uma complicação decorrente de cirurgias orais que podem causar um distúrbio de sensibilidade transitória ou persistente, na região do lábio inferior e na região delimitada do forame mentoniano e hemi-arco da mucosa. O diagnóstico da parestesia pode ser feito através de testes mecanoceptivos e nocioceptivos em que o profissional escolherá para qual melhor se adapte no paciente. O objetivo do presente trabalho foi abordar por meio de uma revisão de literatura as formas de diagnóstico e tratamento da parestesia do nervo alveolar inferior decorrentes de cirurgias orais. As bases de dados utilizadas para confecção desta revisão são encontradas nas bibliotecas virtuais eletrônicas: BVS (Biblioteca Virtual em Saúde), LILACS (Literatura Latino-Americana e do Caribe em Ciências da Saúde) e Pubmed. Como critério de inclusão foram selecionados artigos publicados de 2012 a 2022 em língua inglesa, portuguesa e espanhola. Após a leitura do título e resumo dos resultados da pesquisa e aplicação dos critérios de inclusão e exclusão dentre eles foram excluídos 883, pois não se enquadravam no nosso critério de inclusão. No final, foram selecionados 13 estudos por meio de base de dados, que serviram de base para esta revisão. Concluímos que as formas de tratamento para a parestesia na literatura, são um pouco escassas e conflitantes, mas relata que o uso da laserterapia e acupuntura tem sido uma forma de tratamento com um bom índice de sucesso, e para os casos que não sejam suficientes tais tratamentos, pode-se optar por uma cirurgia(AU)

In dental surgeries it is possible to have some accidents or complications that can interfere with the patient's day. Injury to the inferior alveolar nerve is a complication resulting from oral surgeries that can cause a disturbance of sensitivity that can be transient or persistent in the region of the lower lip and in the delimited region of the mental foramen and hemiarch of the mucosa. The diagnosis of paresthesia can be made through mechanoceptive and nocioceptive tests that the professional will choose, which best suits the patient. The objective of the present work is to approach, through a literature review, the forms of diagnosis and treatment aimed at inferior alveolar nerve paresthesia resulting from oral surgeries. The databases used for this review are found in the virtual electronic libraries: VHL (Virtual Health Library), LILACS (Latin American and Caribbean Literature on Health Sciences) and Pubmed. As inclusion criteria, articles published from 2012 to 2022 in English, Portuguese and Spanish were selected. After reading the title and summary of the research results and applying the inclusion and exclusion criteria, 883 were excluded, as they did not meet our inclusion criteria. In the end, 13 studies were selected from the database, which served as the basis for this review. We conclude that the forms of treatment for paresthesia in the literature are a little scarce and conflicting, but it reports that the use of laser therapy and acupuncture has been a form of treatment with a good success rate, and for cases that are not enough, such treatments, one can opt for surgery(AU)

OBJECTIVES@#This study aimed to analyze the application value of a modified tragus edge incision and transmasseteric anteroparotid approach to condyle reconstruction.@*METHODS@#Condyle reconstruction was performed in 16 patients (9 females and 7 males) with modified tragus edge incision and transmasseteric anteroparotid approach. After regular follow-up, the function of condyle reconstruction was evaluated by clinical indicators, such as parotid salivary fistula, facial nerve function, mouth opening, occlusal relationship, and facial scar. The morphology of rib graft rib cartilage was evaluated by imaging indicators, such as panoramic radiography, CT, and three-dimensional CT image reconstruction.@*RESULTS@#At 6-36 months postoperative follow-up, all patients had good recovery of facial appearance, concealed incisional scar, no parotid salivary fistula, good mouth opening, and occlusion. One case had temporary facial paralysis and recovered after treatment. Radiographic evaluation further showed that costochondral graft survived in normal anatomic locations.@*CONCLUSIONS@#The modified tragus edge incision and transmasseteric anteroparotid approach can effectively reduce parotid salivary fistula and facial nerve injury in condylar reconstruction. The surgical field was clearly exposed, and the incision scar was concealed without increasing the incidence of other complications. Thus, this approach is worthy of clinical promotion.

A long-term evaluation of periodontal phenotypes before and after the periodontal-orthodontic-orthognathic combined treatment of lower anterior teeth in patients with skeletal Angle class Ⅲ malocclusion / 北京大学学报(医学版)

OBJECTIVE@#To evaluate the changes of periodontal phenotype (width of keratinized gingiva, thickness and height of alveolar bone) of lower anterior teeth in patients with skeletal class Ⅲ malocclusion before and after the periodontal-orthodontic-orthognathic combined treatment.@*METHODS@#In the study, 20 patients with skeletal class Ⅲ malocclusion (6 males and 14 females) completed the periodontal-orthodontic-orthognathic combined treatment were included from March 2017 to June 2022, with 39 central incisors, 40 lateral incisors and 40 canines. The mean age was (25.40±4.27) years (20-34 years). The mean follow-up time was (3.70±1.05) years from the beginning of periodontal corticotomy regenerative surgery (PCRS) to the end of the combined treatment. Cone-beam computed tomography (CBCT) was used to measure the thickness, area and height of alveolar bone by the same researcher, taken before the PCRS (T0), 6 months after the PCRS (T1), 12 months after the PCRS (T2), before the orthognathic surgery (T3), and after the periodontal-orthodontic-orthognathic combined treatment (T4). The periodontal clinical parameters were used to evaluate changes in the soft tissue by another researcher, measured before the PCRS (T0) and after the combined treatment (T4). Changes of soft and hard tissue were evaluated by the periodontal phenotype.@*RESULTS@#The width of keratinized gingiva increased significantly (all P < 0.001) in lower anterior teeth, the central incisors, lateral incisors and canines increased by (1.82±1.57) mm, (2.03±1.48) mm and (2.05±1.27) mm, respectively. The proportion of thick periodontal biotype in the central and lateral incisors increased significantly (all P < 0.001), while the changes of periodontal biotypes in the lower canines were not obvious. The thickness of labial alveolar bone of lower anterior teeth all increased significantly after periodontal corticotomy regenerative surgery and the combined treatment (all P < 0.001). The area of labial alveolar bone of lower anterior teeth also increased significantly after the combined treatment (all P < 0.001). The whole area of labial and lingual alveolar bone of central and lateral incisors increased (P < 0.001), while the whole area of canines remained the same. All The height of the alveolar bone increased (all P < 0.001) on the labial side after the treatment.@*CONCLUSION@#The periodontal phenotypes of lower anterior teeth were significantly improved after the periodontal-orthodontic-orthognathic combined treatment in patients with skeletal Angle class Ⅲ malocclusion. The improvement was long-termly stable, and the periodontal risk was reduced.

Waste management practices among dental surgery staff of major hospitals in Accra: a descriptive cross-sectional study

Introduction: the practice of dentistry in contemporary times produces considerable waste that could be harmful to individuals and the environment at large. In Ghana and many other jurisdictions, there are guidelines that outline how these wastes should be managed. This study was conducted to explore practices concerning dental waste management among dental surgery staff in some public facilities in Accra, Ghana. Methods: a descriptive cross-sectional study involving dental surgery staff of four major facilities in Accra was done. Overall, 124 staff from the selected facilities participated in the study, and 51 different dental surgeries were assessed. Data were collected using a structured questionnaire and an observation checklist. The questionnaire included questions on socio-demographics, as well as knowledge and practices regarding dental waste management. Results: there was unsatisfactory knowledge of waste disposal, while practices did not generally meet international recommendations and the Ministry of Health´s (MOH) guidelines. Though all respondents stored their sharp waste in puncture-proof containers, 98.4% did not label their clinical waste, while 62.9% would dispose of used X-ray fixers by pouring them down the drain. None of the 51 surgeries observed had more than one colour code available. Conclusion: there is a palpable need for education, monitoring, and empowerment concerning waste management in Ghana´s oral healthcare system.

Anterior Teeth Measurement among Subjects in the University of Port Harcourt as a Sex Indicator and Aid to Maxillofacial Reconstruction

Background: The aim of this study is to determine sexual dimorphism using anterior teeth measurements and its use as an ancillary tool for sexual determination. Methods:In this study, the measurements of the anterior teeth were carried out on one hundred and forty students (80M: 60F) of the University of Port-Harcourt ranging from 15-30 years. The mesiodistal diameter of the central and lateral incisors, right and left canines and their inter-canine distance were measured. These measurements were done with the aid ofa digital Vernier caliper. Also, the percentages of sexual dimorphism were calculated. The values were subjected to statistical analysis.Results:The mean mesiodistal central incisor (MDCI) value for males was 9.78 ± 0.47mm while that of the females was 9.29±0.46mm. The mean mesiodistal lateral incisor (MDLI) value for males was 7.80 ±0.54mm while that of the females was 7.40±0.54mm. The mean mesiodistal right canine (MDRC) value for males was 7.43±0.49mm while that of the females was 7.04±0.40mm. The mean mesiodistal left canine (MDLI) value for males was 7.39±0.51mm while that of the females was 7.03±0.55mm. The mean mandibular inter-canine distance (MICD) value for males was 33.73±1.15mm while that of the females was 32.23±0.98mm. They were all statistically significantat p<0.05.Conclusion:It can be concluded that the incisors and the canines are useful tools in sex determination. The data obtained can be useful in maxillofacial reconstructive surgery

Sialolitiasis, sialoadenitis y sialoadenosis. Revisión de literatura y reporte de un caso clínico / Sialolithiasis, sialadenitis and sialadenosis. Review of literature and report of a clinical case

Introducción: la formación de sialolitos se considera la alteración más común en las glándulas salivales. Su origen aún no es claro en cuanto a qué provoca la obstrucción parcial o total del sistema de conductos salivales, con una predilección significativa en las glán - dulas submandibulares, lo que permite un desplazamiento retrógrado de bacterias a través del conducto salival hacia la glándula afectada, el cual se traducirá clínicamente como inflamación unilateral o bila - teral. El tratamiento para la sialolitiasis y sialoadenitis puede variar desde un manejo conservador hasta tratamientos que implican la remoción de la glándula salival afectada. La sialoadenosis difiere de las anteriores en su origen, ya que ésta no se considera inflamatoria ni neoplásica y no afecta la función glandular de excretar saliva. Presentación de caso clínico: se trata de paciente masculino con diagnósticos presuntivos de sialoadenitis y sialolitiasis, al cual se le realizó biopsia escisional de la glándula afectada, su estudio histo- patológico corroboró los diagnósticos mencionados anteriormente que además confirmó un diagnóstico de sialoadenosis. Conclusio- nes: la escisión de la glándula salival involucrada se realizará en casos diagnosticados de sialoadenitis y sialolitiasis con sialolitos de gran tamaño y procesos supurativos crónicos que no resuelven con antibioticoterapia (AU)

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.
