Impact of Anxiety on Health-Related Quality of Life and Symptoms of Burnout in Multi-Professional Residents in Brazil During the COVID-19 Pandemic.

We aimed to determine the prevalence of anxiety and to identify associated factors among multi-professional residents in Brazil during the early days of the COVID-19 pandemic. A cross-sectional study included a sample of 752 multi-professional residents selected by snowball technique. Symptoms of anxiety were measured by the Beck anxiety inventory scale (≥ 16 cut-off). We used WHOQOL-BREF to access the health-related quality of life and the Maslach Burnout Inventory to measure the burnout syndrome. PR and respective 95% confidence intervals (CI) were calculated using the Poisson regression model. The prevalence of anxiety was 41.2% (310/752). Some variables were strongly associated with anxiety: afraid of getting COVID-19; extra work demand during COVID-19 pandemic; sweating/wheezing/increased heart rate during work; feeling safe when using personal protective equipment at work, and psychological support from residence preceptors. Residents with symptoms of anxiety showed high emotional exhaustion at work (36.6 ± 9.6 vs. 24.7 ± 10.7, P = 0.001) and depersonalization (8.9 ± 6.0 vs. 5.6 ± 4.9, P = 0.001). Correlations coefficients between emotional exhaustion versus Physical WHOQOL-BREF and between emotional exhaustion versus Psychological WHOQOL-BREF were significantly lower among residents without anxiety (P = 0.027 and P = 0,03, respectively). The prevalence of anxiety was high and strongly associated with several variables, particularly with being afraid of getting COVID-19, the perception of workload, somatization (sweating, wheezing and increased heart rate during work), feeling unsafe when using personal protective equipment, and lack of psychological support from residence preceptors. Anxiety was associated with increased emotional exhaustion and depersonalization and low health-related quality of life during the COVID-19 pandemic in Brazil. Low WHOQOL-BREF environment domain, and high emotional exhaustion MBI domain increased the chances of presenting symptoms of anxiety.

OSLO: On-the-Sphere Learning for Omnidirectional Images and Its Application to 360-Degree Image Compression.

State-of-the-art 2D image compression schemes rely on the power of convolutional neural networks (CNNs). Although CNNs offer promising perspectives for 2D image compression, extending such models to omnidirectional images is not straightforward. First, omnidirectional images have specific spatial and statistical properties that can not be fully captured by current CNN models. Second, basic mathematical operations composing a CNN architecture, e.g., translation and sampling, are not well-defined on the sphere. In this paper, we study the learning of representation models for omnidirectional images and propose to use the properties of HEALPix uniform sampling of the sphere to redefine the mathematical tools used in deep learning models for omnidirectional images. In particular, we: i) propose the definition of a new convolution operation on the sphere that keeps the high expressiveness and the low complexity of a classical 2D convolution; ii) adapt standard CNN techniques such as stride, iterative aggregation, and pixel shuffling to the spherical domain; and then iii) apply our new framework to the task of omnidirectional image compression. Our experiments show that our proposed on-the-sphere solution leads to a better compression gain that can save 13.7% of the bit rate compared to similar learned models applied to equirectangular images. Also, compared to learning models based on graph convolutional networks, our solution supports more expressive filters that can preserve high frequencies and provide a better perceptual quality of the compressed images. Such results demonstrate the efficiency of the proposed framework, which opens new research venues for other omnidirectional vision tasks to be effectively implemented on the sphere manifold.

Instalação de placa de reconstrução e enxerto de crista ilíaca em região de pseudoartrose após osteotomia vertical anterior de mandíbula: relato de caso / Installation of reconstruction plate and ilican crest bone graft in a pseudoartrosis area after anterior vertical osteotomy in the mandible: case report

Introdução: A osteotomia vertical anterior de mandíbula é um procedimento de extrema versatilidade, podendo ser empregado em casos selecionados nos quais a mecânica ortodôntica tem suas limitações. Em contrapartida, existem estudos que demonstram que as complicações deste procedimento incluem a pseudoartrose, neuropraxia, a possibilidade de problemas periodontais e o fato de que esta técnica nem sempre é útil. Relato de Caso: O objetivo deste trabalho é relatar o caso de uma paciente submetida a cirurgia de osteotomia vertical anterior de mandíbula no ano de 2002, evoluindo sem integração óssea e com mobilidade mandibular durante anos, apresentando como queixa principal, a retração gengival. Sendo proposta no ano de 2018, uma reabordagem cirúrgica, com o uso de enxerto da crista ilíaca e placa de reconstrução. Considerações Finais: Conclui-se que o uso de enxerto ósseo autogéno, associado à redução e fixação com placas de reconstrução, são considerados positivos para o tratamento de pseudoartroses, podendo ser considerados como opção durante o tratamento cirúrgico... (AU)

Introduction: The anterior vertical osteotomy of the mandible is an extremely versatile procedure and can be used in selected cases in which orthodontic mechanics have their limitations. On the other hand, there are studies that demonstrate that the complications of this procedure include pseudoarthrosis, neuropraxia, the possibility of periodontal problems and the fact that this technique is not always useful. Case Report: The objective of this study is to report the case of a patient who underwent surgery for anterior vertical osteotomy of the mandible in 2002, evolving without bone integration and with mandibular mobility for years, presenting as the main complaint, gingival retraction. Being proposed in 2018, a surgical re-approach, with the use of iliac crest graft and reconstruction plate. Final Considerations: It is concluded that the use of autogenous bone graft, associated with reduction and fixation with reconstruction plates, are considered positive for the treatment of pseudoarthrosis, and can be considered as an option during surgical treatment...

Remoção de pré-maxila em paciente com fissura labiopalatina: relato de caso / Removal of the premaxilla in patient with cleft lip and palate: case report

Diversas anomalias craniofaciais acometem os seres humanos, dentre estas podem ser citadas as fissuras labiopalatinas. Ocorrem devido à mal formações congênitas e comprometem o desenvolvimento orofacial e maxilo-mandibular, gerando complicações estéticas e funcionais. O momento para abordagem cirúrgica em pacientes com deformidade deste tipo é crucial para atingir o melhor resultado. Entretanto, muitos deles não procuram atendimento ou não tem acesso aos centros especializados. A pré-maxila em portadores de fissura labiopalatina transforame bilateral, não submetidos a tratamento cirúrgico na infância, é comumente protruída, impedindo o desenvolvimento e função adequada da musculatura perioral/ Ainda, pode causar dificuldades alimentares,de fonação e, principalmente, estético. O objetivo do presente trabalho é relatar o caso de uma paciente acompanhada no serviço de cirurgia bucomaxilofacial OSID/UFBA, portadora de fissura labiopalatina, submetida à remoção de pré-maxila em idade adulta. O fechamento da fenda palatina não foi possível devido a idade da paciente e o grau de desenvolvimento do palato, tendo indicado tratamento com uso de prótese obturadora. Considera-se que quanto mais precoce e associado a uma boa técnica cirúrgica forem realizadas as intervenções primárias, menores serão as sequelas. Consequentemente, os resultados estéticos e funcionais serão mais prováveis, sendo desnecessária a remoção cirúrgica da pre-maxila(AU)

Several craniofacial anomalies affect humans and, among these, it can be cited the cleft lip and palate. These occur due to congenital malformations and compromise the orofacial and maxillo-mandibular development, causing aesthetic and functional complications. The moment of the surgical approach in patients with this type of deformities is crucial to achieve the best outcome, however, many of them do not seek care or have no access to specialized centers. The premaxilla in carries of bilateral cleft lip and palate when they are not submitted to a surgical treatment in childhood, is commonly protruding, impeding the development and function of the perioral musculature, besides difficult feeding, phonation and mainly aesthetic. The aim of this article is to report the case of a patient accompained with the Bucomaxillofacial Surgery Service from OSID / UFBA, with cleft lip and palate, submitted to pre-maxilla removal, in adulthood. The cleft palate closure was not possible due to the age of the patient and degree of development of the palate, indicating treatment with obturator prosthesis. It is considered that, the sooner and associated with a good surgical technique, primary interventions are performed, the fewer the sequelae and consequently the aesthetic and functional results, where, in most cases, surgical removal of the premaxilla will be unnecessary(AU)

Evaluation of the Association of Early Implant Failure With Local, Environmental, and Systemic Factors: A Retrospective Study.

PURPOSE: This study aimed to assess the association of early implant failure (EIF) with demographic, local, environmental, and systemic factors. METHODS: Clinical charts of 594 individuals with 2,537 dental implants were assessed. EIF was characterized by implant loss before and up to the abutment connection. Logistic regression analysis was used to verify the association between EIF and local, environmental, and systemic factors at the individual and implant levels. The chosen level of significance was 5%. RESULTS: EIF occurred in 144 implants (5.68%) and in 97 individuals (16.3%). At the individual level, smoking habits (odds ratio [OR] = 2.54; 95% confidence interval [CI] = 1.00 to 6.47; P = .05), absence of postoperative antibiotic therapy (OR = 2.73; CI = 1.22 to 6.13; P = .02), and bone augmentation (OR = 1.83; CI = 1.17 to 2.85; P = .01) were significantly associated with EIF. At the implant level, smoking habits (OR = 2.90; CI = 1.60 to 5.26, P < .001), absence of postoperative antibiotic therapy (OR = 2.77; CI = 1.36 to 5.63, P = .005), postoperative complications (OR = 28.35; CI = 6.79 to 118.45, P < .001), implant length ≤8.5 mm (OR = 1.79; CI = 1.07 to 2.99; P = .03), and diameter <3.75 mm (OR = 1.65; CI = 1.08 to 2.52, P = .02) were associated with EIF. Age, sex, alcohol abuse, diabetes, hypertension, and long-term medication use were not associated with EIF at both individual and implant levels (P ≥ .12). CONCLUSIONS: Smoking habits, absence of antibiotic therapy, bone augmentation, postoperative complications, implant diameter <3.75 mm, and implant length ≤8.5 mm were associated with EIF. Clinicians should be aware of these associations that should be controlled for when feasible. Future cohort studies are required to confirm the risk factors.

Peripheral dentinogenic ghost cell tumor-report of two cases and review of the literature.

Peripheral dentinogenic ghost cell tumor (DGCT) is a rare and non-aggressive benign odontogenic tumor. They usually affect the elderly and are predominantly located in the anterior region of the jaws. Their differential diagnosis includes reactive/inflammatory gingival lesions. We report here two cases of peripheral DGCT in a 73-year-old female and a 48-year-old male patient and review the cases published in the literature. Both lesions presented as a nodular lesion in the mandible, and panoramic radiography showed no abnormalities. Microscopically, it was observed to be an ameloblastomatous epithelial proliferation associated with clusters of ghost cells and dysplastic dentin. Immunohistochemistry revealed positivity for cytokeratin 19 and a low Ki-67 proliferative index. Based on histopathological features and the absence of radiographic findings, a diagnosis of peripheral DGCT was rendered. The low number of cases published of peripheral DGCT makes case reports important in providing information that helps in their diagnoses and management.

Tratamento cirúrgico de sialolito intraglandular: relato de caso / Surgical treatment of intraglandular sialolith: case report

Introdução: O sialolito é a patologia mais frequente nas glândulas salivares maiores, ocorrendo em maior prevalência na glândula submandibular. Os sinais e sintomas clínicos incluem edema e dor na região da glândula acometida pelo sialolito e em caso de obstrução do ducto, os sintomas são mais pronunciados. Existem diversas alternativas de tratamento para a sialolitíase, com indicações específicas de acordo com cada caso. Desse modo, o objetivo desse artigo é relatar a técnica cirúrgica utilizada para remover um grande sialolito localizado no parênquima de glândula salivar maior. Relato de Caso: Paciente do sexo feminino, 49 anos, melanoderma, com queixas álgicas à palpação da região submandibular direita, há aproximadamente oito meses, apresentando discreto aumento de volume enrijecido no local. Ao exame de imagem foi observada imagem radiopaca na região, sugerindo a presença de sialollito no interior da glândula submandibular direita. Conclusão: Diversas modalidades de tratamento são descritas para sialolitíase. O tratamento conservador e/ou minimamente invasivo está indicado para cálculos de pequena dimensão ou extraglandulares e inclui a ordenha da glândula afetada. Cálculos maiores, localizados no interior da glândula, requerem tratamentos mais radicais, e na maioria das vezes, a excisão cirúrgica da glândula é o tratamento de escolha.

Introduction: Sialolith is the most frequent pathology in the major salivary glands, occurring in greater prevalence in the submandibular gland. Clinical signs and symptoms include swelling and pain in the region of the compromised gland by the sialolith and in case of duct obstruction, the symptoms are more evident. There are several treatment alternatives for sialolithiasis, with specific indications according to each case. Thus, the aim of this article is to report the surgical technique used to remove a large sialolith located in the greater salivary gland parenchyma. Case Report: Female patient, 49 years old, black, with complaints of pain on palpation of the right submandibular region, for approximately eight months, with a slight increase in the hardened volume at the site. The imaging exam showed a radiopaque image in the region, suggesting the presence of sialolith in the right submandibular gland. Conclusion: Several treatment modalities are described for sialolithiasis. Conservative and/or minimally invasive treatment is indicated for small or extraglandular calcifications and includes milking of the compromise gland. Larger stones, located inside the gland, require more radical treatments, and most of the time, surgical excision of the gland is the treatment of choice.

Manejo cirúrgico de sequestro ósseo pósexodontia em paciente portador de displasia cemento-óssea florida: relato de caso / Surgical management of post-exodontia bone sequestral in patients with displasia bone cement-florida: case report

A displasia cemento-óssea florida (DCOF) é uma condição não neoplásica, esclerosante limitada aos ossos maxilares, relacionada ao osso do processo alveolar e, na maioria dos casos envolvendo bilateralmente a mandíbula. É uma condição rara que se apresenta nos maxilares, de forma autolimitante, evoluindo de um estágio osteolítico para osteoblástico, com prevalência pelo gênero feminino, de meia idade a idosas, melanoderma. Dessa forma, o objetivo do trabalho é relatar o caso clínico de uma paciente portadora de displasia cemento-óssea florida apresentando osteomielite local após exodontia.Paciente de 57 anos de idade, melanoderma, compareceu ao ambulatório do Hospital Manoel Victorino (Salvador, BA) do serviço de Cirurgia e Traumatologia Bucomaxilofacial, referindo histórico de exodontia do dente 47 há aproximadamente 02 anos, sem cicatrização local e presença de supuração e odor fétido. Ao exame intrabucal notou- se a presença fístula na região do dente 47 com secreção purulenta espontânea e presença de tecido necrótico. Ao exame de imagem (radiografia panorâmica), foi observado presença de lesões radiopacas multifocais das áreas posteriores mandibulares. Foi submetida a cirurgia, sob anestesia geral, para curetagem de sequestro ósseo e fechamento primário do defeito por primeira intenção e acompanhamento. O objetivo do trabalho foi relatar um caso clínico de um sequestro ósseo mandibular em uma paciente com displasia cemento- óssea florida(AU)

Flowery cementum-bone dysplasia (DCOF) is a non-neoplastic, sclerosing condition limited to maxillary bones, related to the alveolar process bone and, in most cases, bilaterally involving the mandible. When infected can lead to suppuration and kidnapping, resulting in a picture of osteomyelitis. It is a rare condition that occurs in the jaws, in a selflimiting way, evolving from an osteolytic stage to osteoblastic, with prevalence by the female gender, from middle age to the elderly, melanoderma. Therefore, the aim of this paper is to report a diagnosed case of florid cemento-ousseous dysplasia, presenting local osteomyelitis after a extraction. Patient 57 years old, melanoderma, attended the outpatient clinic of the Hospital Manoel Victorino (Salvador, BA) of the Bucomaxillofacial surgery and traumatology department, referring to a history of the right mandible exodontia for approximately 2 years, without local scarring and presence of odor and suppuration fetid The intraoral examination revealed the presence of a fistula in the region distal to the tooth 47 with spontaneous purulent secretion and necrotic tissue. At the imaging examination (panoramic radiography), the presence of multifocal radiopaque lesions of the mandibular posterior areas was observed. She underwent surgery under general anesthesia for curettage of bone sequestration and primary closure of the defect by first intention and follow-up. The objective of this study was to report a clinical case of a mandibular bone sequestration in a patient with florid cementoosseous dysplasia(AU)

Systemic risk indicators for peri-implant diseases in individuals with implant-supported fixed prostheses: A cross-sectional study.

PURPOSE: The present study aimed to identify the systemic risk indicators associated with peri-implant mucositis and peri-implantitis in individuals with implant-supported fixed prostheses. MATERIALS AND METHODS: In this cross-sectional study, clinical evaluations of periodontal and peri-implant conditions were performed by a single examiner in a sample of 71 volunteers with 360 implants. Peri-implant mucositis was defined as the occurrence of bleeding on probing in association with redness and swelling or suppuration, without bone loss. Peri-implantitis was defined based on a radiograph of bone loss ≥ 3 mm and/or a probing depth ≥ 6 mm with bleeding and/or suppuration on probing. The systemic factors evaluated were obesity, hormone replacement therapy, osteopaenia and osteoporosis, high blood pressure and hypercholesterolaemia. Logistic models were applied to assess the associations between peri-implant diseases and systemic factors. RESULTS: Mucositis and peri-implantitis were found in 83.1% and 16.9% of the individuals, respectively. The regression analysis showed that obesity (prevalence ratio = 5.23; 95% confidence interval, 1.91 to 96.83; P = 0.01) and high systolic blood pressure (prevalence ratio = 4.23; 95% confidence interval, 1.66 to 12.87; P = 0.03) were associated with peri-implantitis at the individual and implant levels, respectively. No systemic factor was associated with peri-implant mucositis (P ≥ 0.06). CONCLUSION: Obesity and high systolic blood pressure were associated with peri-implantitis, whereas no systemic factor was associated with peri-implant mucositis. Future prospective studies are required to confirm these as true risk factors. Patients with obesity and/or high systolic blood pressure could be informed of the likely association with peri-implantitis, preferably before implant placement.

Infecção odontogênica envolvendo espaço temporal superficial: relato de caso / Odontogenic infection involving surface temporal space: case report

Infecções maxilo-faciais graves são caracterizadas pela disseminação do processo infeccioso aos tecidos adjacentes e espaços fasciais da região de cabeça, pescoço e tórax. Sua principal origem é odontogênica, geralmente resultante de infecção periapical e doença periodontal. Podem variar de infecções bem localizadas de baixa severidade, até infecções graves, com potencial de disseminação para espaços fasciais da cabeça e pescoço, podendo causar o comprometimento de estruturas vitais, septicemia e morte. Essas infecções podem atingir diversos espaços, dentre eles o espaço mastigatório, composto pelos espaços fasciais: submassetérico, pterigomandibular, temporal profundo e temporal superficial. Esses quatro compartimentos do espaço mastigatório, comportamse clinicamente como espaços separados, pois, na maioria dos casos, somente um compartimento torna-se infectado, entretanto, infecções severas ou duradouras podem envolver todos os quatro compartimentos. O objetivo do presente estudo é apresentar o manejo clínico e cirúrgico de infecção odontogênica disseminada para o espaço temporal superficial. Paciente de 51 anos de idade, do sexo feminino, com histórico de infecção odontogênica disseminada para o espaço temporal superficial, tendo como fator etiológico resto radicular da unidade 13. Procedeu-se drenagem ambulatorial do conteúdo associada à antibioticoterapia. Após o período de 07 dias, houve remissão da condição. Apesar de incomum, infecções odontogênicas originadas de dentes anteriores, podem se disseminar para os espaços mastigatórios. Independente de sua origem deve ser tratada de forma imediata, drenando o espaço comprometido, identificando a causa e eliminando-a, e associando o uso de antibióticos como coadjuvante(AU)

Severe maxillofacial infections are characterized by the spread of the infectious process to adjacent tissues and fascial spaces of the head, neck and chest region. Its main origin is odontogenic, usually resulting from periapical infection and periodontal disease. It can range from well-localized infections of low severity to severe infections with potential for dissemination to spread through the facial planes of the head and neck, which can lead to compromised airways, resulting in septicemia and death. These infections can reach several spaces, among them the masticatory space, composed of fascial spaces: subassayeric, pterygomandibular, deep temporal and superficial temporal. These four compartments of the masticatory space behave clinically as separate spaces, since in most cases only one compartment becomes infected, however, severe or long-lasting infections may involve all four compartments. The goal of the present study is to present the clinical management of disseminated odontogenic infection for superficial temporal space. A 51-year-old female patient with a history of odontogenic infection, disseminated to the superficial temporal space, having as the etiological factor the root rest of unit 13. Outpatient drainage of contents and antibiotic therapy-associated was performed. After the period of 07 days, there was remission of the condition. Although uncommon, odontogenic infections originating from anterior teeth may spread to masticatory spaces. Regardless of its origin, it must be treated immediately, draining the compromised space, identifying the cause and eliminating it, and associating the use of antibiotics as a coadjuvante(AU)

Central giant cell granuloma: A clinicopathological and immunohistochemical study of macrophages, blood vessels, lymphatic vessels and regulatory proteins.

OBJECTIVE: This study seeks to investigate immunohistochemical parameters that could distinguish non-aggressive Central giant cell granuloma (CGCG) from aggressive CGCG, two groups of lesions which differ in their clinical and radiographic features and prognosis. MATERIAL AND METHODS: 12 cases of non-aggressive CGCG and 11 cases of aggressive CGCG were investigated and associated the immunohistochemical expression of macrophages (CD68 and CD163), blood vessels (CD34 and CD105), lymphatic vessels (D2-40) and regulator proteins (p63 and Ki-67). Clinical and radiographic features were also studied. RESULTS: Associations between all proteins in non-aggressive and aggressive CGCG were not significant (p > 0.05). With respect to non-aggressive CGCG, there were no significant correlations, while in aggressive CGCG there was a significant positive correlation between CD68 and CD163 (p = 0.031), between CD34 and D2-40 proteins (p = 0.04), whereas a significant negative correlation was observed between CD105 and CD68 (p = 0.040). However, regardless of aggressiveness of CGCG, there was a significant positive correlation between CD68 and CD163 (p = 0,04). Among the clinical and immunohistochemical aspects, only the symptomatology was a significant risk factor for the occurrence of aggressive CGCG (OR = 12.00/p = 0.016). CONCLUSION: Macrophages and angiogenesis contribute to their maintenance and development of CGCG. In addition, immunohistochemistry used here was not able to differentiate their aggressiveness. However, symptomatology was proved to be a risk factor for the occurrence of aggressive CGCG. It is possible that clinical features, particularly symptomatology, represent the most appropriate parameter to attempt to distinguish GCCG.

Retalho miomucoso de língua para fechamento de fístula complexa em palato: relato de caso / Myomucosal tongue flap for closure of complex fistula in palate: case report

As fissuras labiopalatais são malformações congênitas faciais resultantes da falha no mecanismo de fusão dos processos frontonasais laterais com os processos mediais maxilares entre a oitava e a décima segunda semana de vida intrauterina, apresentando uma etiologia multifatorial. O presente estudo teve como objetivo apresentar a utilização de um retalho miomucoso de língua para o tratamento de fístula complexa em palato duro, secundária ao insucesso de uma palatoplastia primária. Paciente do sexo masculino, 15 anos de idade, portador de fissura labial bilateral transforame, apresentou-se ao Hospital Santo Antônio das Obras Sociais Irmã Dulce para tratamento de fístula em região de palato. Após preparo pré-operatório, o paciente foi submetido a procedimento cirúrgico, sob anestesia geral, para fechamento da fístula utilizando-se um retalho pediculado de língua com base na porção anterior da mesma. O retalho foi mantido pediculado cerca de 01 mês, período imprescindível para integração do enxerto na área receptora. Após esse período, realizou-se novo procedimento para soltar o pedículo e moldar o enxerto de tecido mole ao palato. Observou-se no pós-operatório da segunda intervenção, boa integração do enxerto de língua ao palato, fechamento da fístula palatina, permanecendo apenas um pequeno orifício residual comunicando com a cavidade nasal. Constatou-se ainda melhora de funções como dicção das palavras, deglutição e do som anasalado da fala do paciente, e, consequentemente, da sua qualidade de vida. A técnica mostrou-se uma opção efetiva para a reabilitação das grandes fístulas palatinas e exige uma atuação interdisciplinar para execução do protocolo de tratamento(AU)

The labiopalatal fissures are congenital facial badly formations resulting from the failure of the fusion mechanism of the lateral frontonasal processes with the maxillary medial processes between the eighth and tenth week of intrauterine life, presenting a multifactorial etiology. The present study aimed to present the use of a tongue myomucosal flap for the treatment of complex fistula in the hard palate, secondary to the failure of a primary palatoplasty. A 15-year-old male patient with transforame bilateral cleft lip, presented to Hospital Santo Antônio das Obras Sociais Irmã Dulce for treatment of fistula in the palate region. After preoperative preparation, the patient underwent a surgical procedure, under general anesthesia, to close the fistula using a pedicled tongue flap based on the anterior portion of the same. The flap was kept pediculated around 30 days, an essential period for graft integration in the recipient area. After this period, a new procedure was accomplished to drop the pedicle and to shape the soft tissue graft to the palate. In the second intervention, postoperative period, a good integration of the tongue graft to the palate was observed, closing the palatine fistula, remaining only a small residual orifice communicating with the nasal cavity. There was also an improvement in functions such as word diction, swallowing, and the patient's speech nasal sound. The technique proved to be an effective option for the closure of the large palatine fistulas, providing an excellent rehabilitation and, consequently, an improvement in the patient's quality of life(AU)

Avaliação clínica e radiográfica de implantes dentários em área de fissura alveolar / Clinical and radiographic evaluation of dental implants in alveolar fissure area

Introdução: As fissuras labiopalatinas são más formações que causam importantes impactos não só estéticos, auditivos e fonéticos, mas também na integração social de seu portador. Objetivo: Avaliar os aspectos clínicos e radiográficos de implantes osteointegráveis, em região de fissuras labiopalatinas, instalados em um centro de referência em Salvador, Bahia. Material e método: Foi realizado um estudo observacional, no qual foram incluídos todos os pacientes que realizaram implantes dentários osteointegrados em área de fissura alveolar, no período de setembro de 2014 a outubro de 2016. Após análise de prontuários, observaram-se implantes que obtiveram estabilidade secundária, constatada através do travamento bidigital, no momento da instalação dos cicatrizadores; a reconstrução prévia com enxerto de crista ilíaca; a importância do tipo de fissura no resultado do implante; os enxertos complementares realizados em ambiente ambulatorial, bem como a correlação destes fatores com o índice de sucesso dos implantes instalados nessa unidade. Resultado: Foram instalados 15 implantes em 10 pacientes com diferentes tipos de fissura. A taxa de sucesso clínico foi de 80% dos implantes, e, radiograficamente, em apenas um caso houve suspeita de falha na neoformação óssea. Conclusão: Os implantes instalados em região de fissura nos pacientes do centro de referência em Salvador-Bahia, apresentaram clinicamente estabilidade secundária e neoformação óssea sugestiva, clínica e radiograficamente, em níveis semelhantes aos descritos na literatura.

Introduction: The cleft lip and palate are malformations that cause important impacts not only aesthetic, auditory and phonetic, but also in the social integration of its bearer. Objective: To evaluate the clinical and radiographic aspects of osteointegratable implants in a region of cleft lip and palate installed in a reference center in Salvador, Bahia. Material and method: An observational study was carried out in which all the patients who performed osseointegrated dental implants in the area of ​​alveolar fissure were enrolled between September 2014 and October 2016. After analyzing the records, implants were obtained that obtained secondary stability observed through bidigital locking at the time of the installation of the cicatrisers, as well as previous reconstruction with iliac crest graft, type of cleft, as well as complementary grafts performed in an outpatient setting and correlation of these with the success rate of the implants installed in that unit. Result: Fifteen implants were installed in 10 patients with different types of fissures. The clinical success rate was 80% of the implants, and radiographically, in only one case there was suspicion of failure in the new bone formation. Conclusion: Implants located in a region of fissure in the patients of the reference center in Salvador-Bahia presented clinically secondary stability and suggestive bone neoformation clinically and radiographically at levels similar to those described in the literature.

Ameloblastoma with adenoid features: A series of eight cases.

BACKGROUND: Ameloblastoma with adenoid features are characterized by the presence of duct-like structures formed from the parenchyma of the tumor. This study was conducted to report a series of eight ameloblastomas with adenoid features, highlighting their clinicopathological and immunohistochemical aspects. MATERIAL AND METHODS: Out of 71 cases of ameloblastomas, this study classified 8 cases as ameloblastomas with adenoid features. Clinicopathological data and immunohistochemistry for CK7, CK14, CK19, IMP3, p53 and Ki-67 were evaluated. RESULTS: From those cases of ameloblastoma exhibiting adenoid features, there were 4 women and 4 men, with mean age of 39 years. Most cases affected the mandible and all presented radiographically as a radiolucency. The predominant histopathological features were pseudoducts, squamous metaplasia, nuclear hyperchromatism, clear cells, whorled aspect of epithelial structures, cribriform growth pattern, proliferation of spindle cells and extracellular eosinophilic material. Immunohistochemical analysis showed high expression for CK14 (n = 6) and CK19 (n = 3) and all cases (n = 8) were negative for p53, IMP3 and CK7. In addition, all samples (n = 8) showed low expression for Ki-67. CONCLUSIONS: The similarities between the histopathological and immunohistochemical features of eight cases described in the present study and those described in previous studies support the possibility that these lesions are adenoid ameloblastomas. In addition, the immunohistochemical results of CK14, CK19, p53 and Ki-67 did not differ from those of conventional ameloblastomas.

Total bilateral TMJ reconstruction for pain and dysfunction: Case report.

INTRODUCTION: Temporomandibular disorders encompass a set of clinical conditions that affect the temporomandibular joint, the masticatory muscles and the associated tissues. Many therapeutic alternatives can be considered, being divided into non-invasive, minimally invasive and invasive interventions. This work aims to report a case of inflammatory joint pain and dysfunction treated with bilateral TMJ full reconstruction with alloplastic prosthesis stock. CASE REPORT: Patient D.J.S.S., female, 41 years old, hypertensive, for six years had constant pain in TMJ bilaterally, with limitation of mouth opening, with a clinical signs of joint disc displacement without reduction. Initially treated only by conservative approaches. Without improvement, arthrocentesis of the TMJ was performed. The symptoms do not regress, leading the patient to bilateral discopexy procedure. We opted for the alloplastic substitution of the temporomandibular joint with prostheses of stock in both joints through an established protocol. DISCUSSION: The main objective of the reconstruction of the temporomandibular joint in cases of joint bone degeneration is the restoration of form and function, considering the reduction of pain as a secondary result. Alloplastic replacement of TMJ can be considered as an alternative therapy to improve the quality of life of a small group of patients showing signs and symptoms of TMD as a reduction of maximum mouth opening, pain, etc. CONCLUSION: The use of total joint prostheses has been configured as a good therapeutic alternative for severe conditions of TMJ that do not respond to conservative treatments. However, further studies are needed to demonstrate whether these results are long term.

Influence of arthrocentesis irrigation volume at temporomandibular disorder treatment.

INTRODUCTION: Temporomandibular disorder (TMD) treatment varies from conservative therapy to invasive procedures such as arthrocentesis. The procedure is simple and has speed, low cost, low morbidity and good patient acceptance. Literature variations, however, have been found about the type and volume of the solution used for the irrigation of temporomandibular joint (TMJ). SUBJECTS AND METHODS: The aim of this study was to compare the results provided by two different volumes of 0.9% saline solution (100 ml and 250 ml) used in arthrocentesis technique for TMD treatment. It included patients unresponsive to conservative treatment. Preoperative (T0) and postoperative evaluations were performed at T1 (30th day), T2 (60th day), and T3 (90th day), in which maximal mouth opening (MMO), pain, and the presence or absence of joint sounds were recorded. Patients were randomized into two groups: 1 - submitted to arthrocentesis using 100 ml of 0.9% saline solution in TMJ and 2 - arthrocentesis performed using 250 ml of 0.9% saline solution in each TMJ. Data were submitted to descriptive and comparative analyses for each parameter per group and between groups. The effect size was calculated according to Cohen test. Minimum detectable change (MDC) was obtained and the sensibility was calculated. A statistical significance of 5% was established. Group 1 obtained increase in MMO and decrease in pain (statistically significant); in Group 2, pain decreased significantly. In Group 1, clicking decreased significantly. No statistical differences were found between groups (P = 0.333). MMO and pain results exceeded MDC, and sensibility was good. CONCLUSION: In conclusion, arthrocentesis is effective in TMD symptoms' relief, without statistical difference between the volumes used.

Reconstrução maxilar utilizando enxerto pela técnica tunelização subperiosteal / Maxillary reconstruction using graft by subperiosteal tunneling technique

A implantodontia nas últimas décadas vem se modernizando e lançando mão de opções de tratamento capazes de atender, de forma satisfatória, as necessidades funcionais e estéticas de pacientes desdentados, apresentando resultados com alto grau de excelência. Para defeitos ósseos encontrados nos maxilares devido à atrofia, pós-exodontia, de origem fisiológica ou até mesmo por processos patológicos, geralmente tem-se a necessidade da reconstrução óssea na região para viabilizar a reabilitação oral com implantes dentários. Dentre as opções de enxertos disponíveis, os autógenos intrabucais são considerados "padrão-ouro" para reconstrução de defeitos alveolares maxilares e mandibulares devido às características ideais para promover morfogênese óssea, menor incidência de infecção, menor custo e maior previsibilidade. Este trabalho tem como objetivo apresentar um caso clínico de enxerto autógeno pela técnica de tunelização subperiosteal em região anterior da maxila atrófica, demonstrando a vantagem de ser realizado de forma rápida e com menor morbidade ao paciente...

Implantology in the last decades has been modernizing and using treatment options capable of satisfying the functional and aesthetic needs of edentulous patients with results with a high degree of excellence. For bone defects found in the jaws due to atrophy, post discharge, physiological origin or even pathological processes, there is usually a need for bone reconstruction in the region to enable oral rehabilitation with dental implants. Among the available graft options, intraoral autogenous grafts are considered "gold standard" for the reconstruction of maxillary and mandibular alveolar defects, due to the ideal characteristics to promote bone morphogenesis, lower incidence of infection, lower cost and greater predictability. This study aims to present a clinical case of autogenous graft by the technique of subperiosteal tunneling in the previous region of the atrophic maxilla, demonstrating the advantage of being performed quickly and with lower morbidity to the patient...

Glossectomia parcial associada à cirurgia ortognática: relato de caso / Partial glossectomy associated with orthognathic surgery: case report

A macroglossia é caracterizada pelo aumento de volume da língua, a qual afeta todo o sistema estomatognático em função de sua posição e tamanho. Ela é considerada um fator etiológico para: mordida aberta, protrusão bimaxilar, espaçamento entre os arcos dentários e pode causar instabilidade pós-tratamento ortodôntico/ortodôntico-cirúrgico. Aglossectomia é uma cirurgia com prognóstico favorável, pois melhora a estabilidade oclusal, esta pode ser associada antes, simultaneamente ou após a cirurgia ortognática. Nos casos em que o tamanho da língua inviabiliza a realização da cirúrgiaortognática. Descrever um relato de caso de glossectomia associada à cirurgia ortognática, apresentando o diagnóstico, tratamento instituído, técnica cirúrgica e acompanhamento pós operatório. Paciente sexo feminino, acompanhada há 10 anos pelo preceptor do serviço foi submetida à cirurgia ortognática e glossectomia em mesmo tempo cirúrgico, com retração mandibular instituída através de osteotomia bilateral e fixação com duas placas no sistema 2.0. A técnica selecionada para a glossectomia foi de "buraco de fechadura" modificada sem avançar a incisão muito a posterior. Não houve sequelas e a paciente ficou muito satisfeita com o resultado. A macroglossia é uma condição de difícil diagnóstico que precisa ser tratada para uma melhor qualidade de vida e desenvolvimento do paciente, melhor resultado pós operatório em cirurgias ortognáticas, evitar recidivas devido a memória muscular e a influência da língua na posição alvéolo dentaria(AU)

The macroglossia is characterized by an increase in the volume of the tongue, which affect the entire stomatognathic system in function of the tongue position and size. It is considered an etiological factor for: open bite, bimaxillary protrusion, spacing between dental arches and may cause orthodontic / orthodontic-surgical post-treatment instability. Glossectomy is a surgery with favorable prognosis, because cause a improvement of occlusal stability, may be associated before, simultaneously or after an orthognathic surgery. In cases where the size of the tongue makes it impossible to perform orthognathic surgery. To describe a case report of glossectomy associated with orthognathic surgery, presenting the diagnosis, treatment instituted, surgical technique and postoperative follow-up. Female patient, followed for 10 years by the preceptor of the service. She had been submited toaorthognathic surgery and glossectomy in one surgical time, with mandibular retraction instituted through bilateral osteotomy and fixation with two plaques in the 2.0 system. The technique selected for glossectomy was a modified "keyhole" without advancing the incision much later. There were no sequels and patient was very satisfied with the result. Macroglossia is a difficult diagnosis condition that needs to be treated for a better quality of life and development of the patient, better postoperative result in orthognathic surgeries, to avoid relapses due to a Muscular memory and the influence of the tongue in the dental alveolus position(AU)

Appositional bone graft tunneled: Technical note.

INTRODUCTION: A satisfactory positioning of the dental implants is very important in the cosmetic and functional outcome in this treatment for edentulous. Insertion of an endosseous implant in the correct positioning requires sufficient bone volume. Therefore, bone-grafting procedures are becoming increasingly common, especially for the augmentation of horizontally deficient ridges. PRESENTATION OF CASE: Many patients have been treated with this technique of appositional Bone Graft Tunneled at our clinic since 2005. The method will be completed through the technical note of a surgical procedure involving a dental implant used for edentulous space rehabilitation in the jaws and the tunnel technique with an appositional bone graft, using the mandibular arch as the donor area. DISCUSSION: The substitution of screws to stabilize the bone graft for the tunnel technique allowed the surgery to be performed in a shorter time. The advantages were as follows: the absence of complications associated with conventional titanium screws, the preservation of the integrity of the periosteum, and the fact that there was no need to remove the screws through relaxing incisions in the gingival mucosa before placing the implant. CONCLUSION: The tunnel technique for onlay bone grafting is a simple and easy to perform technique, which is completed with less surgical time and at a lower cost and has presented highly predictable results and high success rates.

Ressecção de ameloblastoma por abordagem intra-oral, vantagens e desvantagens através da apresentação de um caso clínico / Ameloblastoma of resection in approach intra-oral, advantages and disadvantages through the presentation of a case

O objetivo desde trabalho é relatar e discutir um caso de um paciente com ameloblastoma multicístico mandibular que compareceu ao ambulatório do Serviço UFBA/ OSID de Cirurgia e Traumatologia BucoMaxiloFacial cuja ressecção e reconstrução foi realizada por via intra-oral em um tempo único, comentando as vantagens e desvantagens dessa opção terapêutica. Paciente foi encaminhada ao centro cirúrgico para ressecção do ameloblastoma sob anestesia geral. Foi realizada a ressecção parcial da mandíbula com 01cm de margem de segurança. O acesso à lesão foi todo realizado por intra-oral. Procedeu-se a ressecção do tumor, o defeito ósseo foi de aproximadamente 5 cm. A placa de reconstrução foi instalada, reestabelecendo a correta relação insterfragmentos e intermaxilares, e na região do defeito foi interposto um enxerto ósseo livre em bloco tricortical removido da crista ilíaca direita para reconstrução imediata. Conclusão: A abordagem intra-oral para tratamento e reconstrução de neoplasias benignas em região mandibular é uma forma segura e confiável, tendo como principais vantagens à ausência de cicatriz, integridade do nervo facial. E como desvantagens a contaminação por conta das secreções bucais, a infecção do enxerto levando a perda de todo o osso além de ser uma abordagem difícil requerindo habilidade do cirurgião,quando comparado com a abordagem extra-oral, sendo uma técnica bem indicada em casos selecionados(AU)

The aim of this work is to report and discuss a case of a patient with ameloblastoma mandibular multicystic who attended the outpatient clinic of UFBA Service / OSID of Oral and Maxillofacial Surgery whose resection and reconstruction was performed by intraorally in a single time, commenting on the advantages and disadvantages of this therapeutic option. The patient was referred to the operating room for resection of ameloblastoma under general anesthesia. partial resection of the mandible with 01cm margin of safety was performed. Access the injury was all done by intraoral. Proceeded to tumor resection, the bone defect was approximately 5 cm. The reconstruction plate was installed, reestablishing the correct insterfragmentos and intermaxillary relationship, and the defect region was brought a free bone graft in tricortical block removed from the right iliac crest for immediate reconstruction. Conclusion: The intraoral approach to treatment and reconstruction of benign neoplasms in mandibular region is a safe and reliable way, the main advantage of the absence of scarring, facial nerve integrity. The disadvantages contamination because of oral secretions, infection of the graft leading to loss of the entire bone and is a difficult approach requerindo surgeon's skill, compared to the extra-oral approach, being a technique indicated in selected cases(AU)
