The aim of this study was to determine the influence of mouthrinses on the surface roughness of a nanofilled composite resin after toothbrushing. One hundred nanofilled composite resin specimens were prepared and randomly distributed into two groups-brushed and non-brushed-and then assigned to five subgroups, according to the mouthrinse solutions (n = 10): Colgate Plax Fresh Mint, Oral B, Cepacol, Colgate Plax, and artificial saliva. Each sample was immersed in 20 mL of the mouthrinses for 1 minute, 5 days per week, twice a day, for a 3-week period. The control group used in the study was one in which the specimens were not subjected to brushing and remained only in artificial saliva. Toothbrushing was performed once a week for 1 minute, for 3 weeks. Surface roughness measurements (Ra) were performed after the immersion period and toothbrushing, by means of a profilometer. Data were analyzed by two-way ANOVA and Tukey's test. Analysis revealed that the association between toothbrushing and Colgate Plax Fresh Mint produced the lowest surface roughness (p < 0.05). All other groups tested (Oral B, Cepacol, Colgate Plax, artificial saliva) exhibited no statistically significant differences between surfaces, whether subjected to toothbrushing or not (p < 0.05). It was concluded that the surface roughness of the nanofilled composite resin tested can be influenced by the mouthrinse associated with toothbrushing.
RESUMOO edentulismo tem sido um problema comum no Brasil e no mundo, resultado de uma prática odontológica com foco no tratamento e não na prevenção de doenças. Uma opção de tratamento para pacientes edêntulos é a confecção de próteses totais mucossuportadas, que repõem tanto os dentes como as estruturas adjacentes perdidas. O objetivo deste trabalho foi exemplificar a necessidade do cuidado de todas as etapas operacionais e complementares na confecção de próteses totais mucossuportadas. Apresenta-se uma paciente com 50 anos de idade, que procurou a clínica de odontologia da Universidade do Extremo Sul Catarinense, com a necessidade da troca das próteses totais por fatores estéticos e funcionais. Após os exames clínico e complementares, pôde-se observar o tecido bucal livre de lesões ou hiperplasias e as próteses sem retenção e desgastas pelo tempo de uso. Radiograficamente constatou-se a presença de restos radiculares na região do 17 e, posteriormente, foi verificado que a paciente nunca tinha realizado nenhum tipo de radiografia bucal antes de qualquer procedimento dentário como extrações ou da confecção das próteses totais antigas. O mais provável seria que essas raízes surgissem após a reabilitação pela compressão das novas próteses, podendo causar o insucesso do tratamento. Por isso, optou-se pela extração das mesmas e posterior reabilitação. Assim, conclui-se que exames complementares relativamente simples e acessíveis como uma radiografia oclusal são importantes e necessários para a realização de uma reabilitação oral satisfatória.

ABSTRACTEdentulism, a common problem in Brazil and worldwide, results from dental practice focused on treatment rather than disease prevention. A treatment option for edentulous patients is making mucossupported dentures, which replaces not only teeth as the lost adjacent structures. The aim of this study was to exemplify the need for care in all operative and complementary stages of rehabilitation with complete, mucosupported dental prostheses. The case is presented, of a 50-year-old patient, who came to the "Universidade do Extremo Sul Catarinense" (Unesc) dental clinic, with the need to replace complete dentures for esthetic and functional reasons. After clinical and complementary exams, oral tissues are free of lesions or hyperplasia, and poorly worn retained dentures, due to time of use could be observed. Radiographs showed the presence of root remainders in the region of tooth 17. Afterwards it was found that the patient had never had any type of oral radiograph taken before any dental procedure, such as extractions, or fabrication of the existent dentures. Most probably these roots appeared after the previous rehabilitation, due to compression by the existent dentures, which may cause treatment failure. Therefore, the option was to extract the roots, and then perform rehabilitation. Thus, it was concluded that relatively simple and accessible complementary exams, such as occlusal ra...
Bisphosphonates are drugs used for the inhibition of osteoclastic bone resorption. Their therapeutic use is indicated for Paget's disease, hypercalcemia of cancer, bone metastases, and osteoporosis. The main side effect of these drugs is osteonecrosis of the jaw, which is difficult to control. The aim of the present study was to report a patient, who was referred to the Special Needs Clinics of the Ribeirão Preto Dental School, University of São Paulo, for dental treatment. His medical history revealed a diagnosis of multiple myeloma with bone marrow transplantation in November 2007. Since then, he has been using zometa every 3 months. After physical examination and complementary exams, a diagnosis of angular cheilitis, erythematous candidiasis, caries, localized chronic periodontitis, pulp necrosis and partial edentulousness was established. The treatment plan was based on control of angular cheilitis candidiasis, basic periodontal therapy, supportive periodontal therapy, endodontic treatment, and partial mandibular and maxillary dentures. All invasive procedures were performed with antibiotic prophylaxis. The patient is under treatment and care is being taken to avoid osteonecrosis of the jaws. The authors highlight the need for knowledge of the side effects of bisphosphonates to prevent such effects and to maintain the oral health of the patients. RESUMOOs bisfosfonatos são drogas empregadas para inibição da reabsorção osteoclástica. Seu uso terapêutico está indicado na doença de Paget, hipercalcemia, metástases ósseas e osteoporose. Dentre os efeitos colaterais dessas drogas destaca-se a osteonecrose dos maxilares; lesões de difícil controle. Apresenta-se um caso de paciente que foi encaminhado ao serviço de atendimento odontológico a pacientes com necessidades especiais (DAPE) da Faculdade de Odontologia de Ribeirão Preto -USP para tratamento odontológico. A história médica revelou mieloma múltiplo submetido a transplante de medula óssea em novembro de 2007, e desde então usando zometa a cada 3 meses e carbonato de cálcio (CaCO3). Após exame físico e exames complementares estabeleceu-se o diagnóstico de: queilite angular, candidíase eritematosa, cárie, periodontite localizada, necrose pulpar, desdentamento parcial. Como plano de tratamento foi proposto: controle da queilite angular e candidíase, terapia periodontal, tratamento endodôntico e confecção de prótese parcial removível superior e inferior. Todos os procedimentos invasivos foram feitos sob antibioticoprofilaxia. O paciente encontra-se em tratamento, e cuidados estão sendo tomados para evitar a ocorrência de osteonecrose. Os autores destacam a necessidade do conhecimento dos efeitos colaterais dos bisfosfonatos, no intuito de prevenir tais efeitos e manter a saúde oral de seus pacientes.
ResumoAs próteses totais convencionais inferiores são as mais difíceis de adaptar, devido à perda óssea ser maior e consequentemente à baixa estabilidade e pouca retenção. Entretanto, com o aparecimento dos implantes osseointegráveis surgiram os tratamentos com próteses do tipo overdenture, as quais oferecem melhor estabilidade e retenção. O objetivo deste trabalho foi comparar os três principais tipos de sistemas de retenção para a pró-tese overdenture encontrada na literatura. Para isso, foram realizadas pesquisas com os termos "overdenture"; "attachment", "implant-supported", "dental prosthesis", "denture" e "oral rehabilitation" nas bases de dados PubMed, Science Direct e Scielo. Os sistemas barra-clipe e esférico apresentaram semelhanças estatísticas quanto à retenção e estabilidade. Já o sistema magnético apresentou pouca retenção e baixa estabilidade.

AbstractThe conventional lower total prosthesis is the most difficult dental prosthesis to adapt in the patients mouth, due to bone loss be greater in this region, which consequently decreases stability and retention of the prosthesis. However, the appearance of osseointegrated implants gave rise to treatments with overdenture prostheses, which offer better stability and retention to the prostheses. The aim of this study was to compare the three main types of overdenture prosthesis restraint systems found in the literature. For this research, we used the terms: "overdenture"; "attachment", "implant-supported", "dental prosthesis", "denture" and "oral rehabilitation" in the databases of PubMed, Science Direct and Scielo. The clip bar and spherical systems presented statistical similarities regarding retention and stability. Already, the magnetic system presented little retention and low stability.
