Orientador: Elaine Maria Sgavioli Massucato / Banca: Jorge Esquiche León / Banca: Lays Martin Sobral / Resumo: O carcinoma espinocelular (CEC) representa mais de 95% de todas as neoplasias malignas que acometem a cavidade oral e muitas vezes estes tumores são precedidos por alterações clínicas que apresentam um evidente potencial de transformação maligna, as quais são chamadas de desordens potencialmente malignas orais (DPMO). Dentre estas, a leucoplasia oral (LO) é a principal condição dentre as DPMOs com uma taxa de incidência igual a 3,4% e uma taxa de transformação maligna que varia de 0,2% até 17,5%. Uma forma menos reconhecida e ainda pouco compreendida de LO denominada leucoplasia verrucosa proliferativa (LVP), representa uma variante de comportamento persistente e progressivo para malignidade, com uma taxa de transformação maligna ocorrendo em mais de 70% dos casos. O diagnóstico da LVP atualmente só é possível através da observação temporal e individual de cada paciente, com a demonstração de progressão clínica e histológica das lesões para um CEC. A dificuldade no diagnóstico precoce da LVP decorre da sobreposição de características clínicas e histopatológicas, especialmente em casos de LO multifocal convencional. Portanto, foi proposto inicialmente realizar a classificação de casos multifocais de LO encontrados no Serviço de Medicina Bucal da Faculdade de Odontologia de Araraquara - UNESP, durante os anos de 1995 até 2015, segundo descrição da Organização Mundial da Saúde (OMS, 2005) e critérios diagnósticos para LVP atualmente propostos por Cerero-Lapiedra (2010) e Carrard (2013). Posteriormente, foi realizada uma análise comparativa entre as características clínicas e microscópicas de casos de LVP e LO. Os resultados deste estudo revelaram que dentre 86 casos de LO, 45 casos apresentaram o envolvimento de dois ou mais sítios orais configurando estes como casos de LO multifocal. Segundo avaliação realizada por dois observadores experientes...(Resumo completo, clicar acesso eletrônico abaixo) / Abstract: The squamous cell carcinoma (SCC) represent more than 95% of all the malignant neoplasia of the oral cavity and most of times these tumors are preceded by clinical conditions that have a potential for malignant transformation called oral potentially malignant disorders (OPMD). Among these, the oral leukoplakia (OL) is the most important OPMD, with an incidence rate of 3.4% and a malignant transformation from 0.2 to 17.5%. A form less recognized and poorly understood of leukoplakia is the proliferative verrucous leukoplakia (PVL) which represents a variant with a persistent and progressive to malignancy behavior, with a malignant transformation ratio up to 70% of cases. Currently, the diagnosis of PVL is only made by the temporal and individual observation of each patient, with the demonstration of clinical and histopathological progression to an SCC. The difficult to stablish an early diagnosis of PVL comes from the overlap of clinical and histopathological features with conventional multifocal OL cases. Therefore, was initially proposed to perform a classification of multifocal OL cases found in the Oral Medicine Service from the Araraquara Dental School - UNESP, between 1995 and 2015, according to the WHO definition (WHO, 2005) and the current suggested diagnostic criteria for PVL by Cerero-Lapiedra (2010) and Carrard (2013). Lately, a comparative analysis was conducted between the clinical and microscopic features from cases of PVL and OL. The results of this study revealed that between 86 cases of OL, 45 presented involvement of two or more setting this as multifocal OL cases. According to the evaluation by two experts, 14/45 were considered true cases of PVL. The classification of the same 45 cases by the WHO definition revealed 21/45 cases as PVL, by the Cerero-Lapiedra 27/45 cases were PVL and 4/45 cases were PVL according to Carrard.

Magister Scientiae Dentium - MSc(Dent) / Between September 1992 and August 1995, all patients with haematological malignancies who were treated as in-patients in the Haematology Unit at Groote Schuur Hospital received a twice weekly, oral and perioral examination. Sixty patients were monitored while following the traditional hospital oral care protocol (chlorhexidine, hydrogen peroxide, sodium bicarbonate, thymol glycol, benzocaine mouthrinse and nystatin). The mouth care protocol was then changed (protocol A = chlorhexidine, benzocaine lozenges, amphotericin B lozenges) and patients monitored until the sample size matched that of the hospital mouth care regimen (n = 60). A further 60 patients were then monitored using a third protocol (protocol B = benzydamine hydrochloride, chlorhexidine, benzocaine lozenges, amphotericin B lozenges). A statistically significant reduction in oral complications was found upon introduction and maintenance of protocols A and B. The findings of this study suggest that improved oral care and a structured oral care routine reduces the number of oral complications associated with chemo- and radiotherapy. / Medical Research council

As lesões ósseas são doenças raras, mas com um grande destaque, que afetam a região maxilofacial. Dentre elas podemos destacar as Lesões Centrais de Células Gigantes e as Lesões Fibro-Ósseas Benignas (Displasia Cemento-Ossificante, Fibroma Ossificante e Displasia Fibrosa). O presente estudo teve como objetivo descrever e analisar os dados encontrados nas fichas de encaminhamento clínico presentes no Serviço de Patologia Oral e Maxilofacial da Faculdade de Odontologia da Universidade de São Paulo. Foram avaliados 89.265 casos em um período que variou de 1950 até 2016, utilizando as categorias de gênero, idade, etnia, sintomatologia, hipótese diagnóstica e localização anatômica. Após as exclusões, os casos selecionados somavam 773 casos divididos em: 267 casos de Lesão Central de Células Gigantes, 231 casos de Displasia Cemento Ossificante, 142 casos de Fibroma Ossificante e 133 de Displasia Fibrosa. Os resultados do estudo estão de acordo com o que está descrito na literatura, exceto nos casos de Displasia Fibrosa que foi encontrado uma predileção maior sexo feminino do que o masculino, mesmo que a literatura expresse que não existe tal predileção. Já nos casos de Displasia Cemento-Ossificante, o presente estudo mostrou que a maior prevalência de idade é entre a 4ª e 5ª década de vida e não entre a 3ª e 4ª como encontrado na literatura. Os casos de Displasia Cemento-Ossificante, em relação à etnia dos pacientes, mostraram que a maioria dos pacientes encontrados pelos autores eram leucodermas e não melanodermas como relata a literatura. Os resultados mostraram que mesmo em um centro de referência como o Serviço de Patologia Oral da Faculdade de Odontologia da Universidade de São Paulo, as lesões ósseas são raras e alguns fatores como idade em pacientes com Displasia Fibrosa e Displasia Cemento-Ossificante e etnia em pacientes com Displasia Cemento-Ossificante não correspondem ao encontrado na literatura mundial. / Bone lesions are rare but important diseases that affect the maxillofacial region. Among them we can highlight the Central Giant Cells Lesion and the Benign Fibro-Osseous Lesions (Cemento-Osseous Dysplasia, Ossifying Fibroma and Fibrous Dysplasia). The objective of this study was to describe and analyze the data found in the clinical referral forms present at the Oral and Maxillofacial Pathology Service of the Faculty of Dentistry of the University of São Paulo. We evaluated 89.265 cases in a period ranging from 1950 to 2016, using the categories of gender, age, ethnicity, symptomatology, diagnostic hypothesis and anatomical location. After the exclusions, the selected cases totaled 773 cases divided into 267 cases of Central Giant Cell Lesion, 231 cases of Cemento-Osseous Dysplasia, 142 cases of Ossyfing Fibroma and 133 cases of Fibrous Dysplasia. The results of the study are in agreement with what is described in the literature, except in the cases of Fibrous Dysplasia that a predilection was found greater female than the male, even if the literature expresses that there is no such predilection. In the cases of Cemento-Osseous Dysplasia, the present study showed that the highest prevalence of age is between the 4th and 5th decade of life and not between the 3rd and 4th as found in the literature. The cases of Cemento-Osseous Dysplasia, in relation to the ethnicity of the patients, showed that the majority of the patients found by the authors were white and not black as reported in the literature. The results showed that even in a reference center such as the Oral Pathology Service of the Faculty of Dentistry of the University of São Paulo, bone lesions are rare and some factors such as age in patients with Fibrous Dysplasia and Cement-Ossificante Dysplasia and ethnicity in patients with Cement-Ossific Dysplasia do not correspond to that found in the world literature.

Third molar surgery may be associated with a number of complications the most common of which are postoperative pain, swelling and trismus, and dry socket formation. The appearance of these post-operative sequelae is intimately related to the manifestations of inflammation in response to tissue injury. There is significant post-operative morbidity associated with these complications and it was thus the objective of this study to - investigate the effect of a combined antibiotic/anti-inflammatory intrasocket medication on post-operative pain, swelling and dry socket formation. The medication chosen for the study was Covomycin D®. Covomycin D® is a commercially prepared opthalmological preparation - each 1 millilitre contains 2 mg chloramphenicol, 5 mg neomycin sulphate and 0,5 mg dexamethasone. Nineteen subjects were included in the study after fullfilling certain criteria. All subjects were operated under general anaesthesia by the same surgeon. The patients were blinded to the side of the medication and were asked to complete a pain visual analogue scale and note the side of the worst swelling in the post¬operative period. All patients were followed up in the first week following surgery by an independent oral and maxillofacial surgeon who was also blinded to the side on which the medication was placed. The results showed a significant difference (p<0.6) in the pain experienced on the non-medicated compared to the medicated side on day one in eleven of the nineteen patients (57.9%). When the data was analysed over the six day postoperative period sixteen of the nineteen patients (84.2%) had significantly less pain on the medicated side compared to the non-medicated side (p<0.6). The swelling was reported as being worse on the non-medicated side in fourteen out of the nineteen patients (73.7%). Dry socket occurred in three out of nineteen patients or three out of thirty eight surgical extraction sites; an overall incidence of 7.9% or an incidence of 0% for the medicated side and an incidence of 15.8% on the non-medicated side i.e. all the dry sockets occurred on the non-medicated side. In conclusion, this double-blinded prospectve study, showed that the use of a combined antibiotic/anti-inflammatory intrasocket medication favourably influences the common adverse post-operative sequelae following the removal of lower third molars. / Dissertation (MChD (Chir Max-Fac Med))--University of Pretoria, 2007. / Maxillo-Facial and Oral Surgery / unrestricted

Liver transplantation is the gold standard treatment for patients with cirrhosis and hepatocellular carcinoma. The Brazilian Registry of Transplantation revealed that liver transplantation was the second solid organ most transplanted in 2010. With the purpose to eliminate foci of infection and reduce the risk of infection on the postransplant stage, these patients should undergo dental treatment to the removal of dental foci, with special care regarding the hemostasis impairment, mainly related to a reduced hepatic synthesis of procoagulants factors and thrombocytopenia. The aim of this prospective study was to evaluate the incidence of postoperative bleeding after dental extraction in candidates for liver transplantation. In this study, 23 patients were included with a mean age of 43.17  14.62 years, with a higher prevalence of whites (82.6%) and men (60.9%). In 23 patients, 84 simple extractions were performed in 35 dental surgical procedures. Patients were divided in two groups to compare two local hemostatic measures after tooth extraction: in group 1, local pressure after sutures was applied with gauze soaked with tranexamic acid, and in group 2, the same procedure without the tranexamic acid was performed. In all subjects, absorbable hemostatic sponges and cross sutures were used as a standard hemostatic measure. The main preoperative blood tests found were: mean hematocrit of 34.54% (SD  5.84%, range 21.7% â 44.4%), platelets ranged from 31,000/mm3 to 160,000/mm3, mean international normalized ratio (INR) was 1.50 (SD  0.39; range 0.98 - 2.59). Postoperative bleeding occurred in only one procedure (2.9%) and local pressure with gauze was effective to achieve hemostasis. Thus, this paper demonstrates the possibility of performing tooth extractions in patients with liver cirrhosis, with INR &#8804; 2.50 and platelets &#8805; 30,000/mm3, without the need of blood transfusion, and in case of bleeding events, the use of local hemostatic measures can be satisfactory. / O transplante hepÃtico à o tratamento padrÃo para pacientes com cirrose hepÃtica e carcinoma hepatocelular. Dados do Registro Brasileiro de Transplantes (RBT) demonstraram que o transplante hepÃtico foi o segundo ÃrgÃo sÃlido mais transplantado em 2010. Para eliminar focos de infecÃÃo e reduzir o risco infeccioso na fase pÃs-transplante, esses pacientes devem passar por uma avaliaÃÃo odontolÃgica minuciosa para remoÃÃo dos focos de origem dental. No caso de procedimentos odontolÃgicos que gerem sangramento, o cirurgiÃo-dentista deve dar atenÃÃo especial para a hemostasia, devido, principalmente, à reduÃÃo da sÃntese hepÃtica de fatores da coagulaÃÃo e trombocitopenia. O objetivo deste estudo prospectivo foi avaliar a incidÃncia de hemorragia pÃs-operatÃria de exodontias em pacientes na fila de espera por um transplante de fÃgado. Nesse estudo foram incluÃdos 23 pacientes com idade mÃdia de 43,17  14,62 anos com predominÃncia da raÃa branca (82,6%) e do sexo masculino (60,9%). Nos 23 pacientes, 84 exodontias simples foram realizadas em 35 procedimentos cirÃrgicos. Os pacientes foram divididos em dois grupos para comparaÃÃo de duas medidas hemostÃticas locais apÃs as exodontias: no grupo 1, aplicou-se pressÃo local com gaze embebida em Ãcido tranexÃmico, e no grupo 2, realizou-se a mesma conduta sem o uso do referido Ãcido. Em todos os pacientes foram utilizadas a esponja de colÃgeno reabsorvÃvel e sutura em X como medida hemostÃtica padrÃo. Os valores encontrados para os exames hematolÃgicos foram: hematÃcrito mÃdio de 34,54  5,84% (intervalo de 21,7% â 44,4%), plaquetometria variou de 31.000/mm3 a 160.000/mm3 e o Ãndice mÃdio encontrado para a razÃo internacional normatizada (INR) foi 1,50  0,39 (intervalo de 0,98 â 2,59). Sangramento pÃs-operatÃrio ocorreu apenas em um procedimento (2,9%) e a pressÃo local com gaze foi eficaz em parar o episÃdio de hemorragia. Dessa forma, esse trabalho demonstra a possibilidade da realizaÃÃo de exodontias em pacientes com cirrose hepÃtica com valores de INR &#8804; 2,50 e plaquetometria &#8805; 30.000/mm3 sem a necessidade de transfusÃo sanguÃnea e que diante da ocorrÃncia de intercorrÃncias hemorrÃgicas, o uso de medidas hemostÃticas locais pode ser satisfatÃrio.
