Various surface treatments of dental implants have been developed in order to ensure anchorage to bone tissue, optimization of the determinants of electronic structure, crystallinity, composition and properties. Coating techniques have been proposed in order tocreate unionbiochemicalable to accelerate the early stages ofbone tissue, combining the positive properties of titanium and its alloys bioactivity of ceramic materials. This paper discusses protocol for handling the SBF coating of titanium alloys. The apatite phase nucleation occurs by immersing the substrate in synthetic solution simulating blood plasma (Simulated Body Fluid). The protocol allows manipulation of the SBF solution to establish guidelines regarding the usestreamlinedand organized to make practical application.

O traumatismo dentoalveolar é uma ocorrência cada vez mais comum na população em geral e está relacionado, na maioria das vezes à violência no trânsito, violência urbana e à prática esportiva. Esse aspecto, por conseguinte, tem aumentado sobremaneira o número de pacientes que procuram o tratamento ortodôntico e que relatam ter passado por algum episódio de trauma em seus dentes. Dentro desse contexto, muitas questões surgem com relação ao manejo de dentes com histórico de traumatismo dentoalveolar. Do ponto de vista histológico, quais as diferenças em movimentar-se um dente com histórico de trauma? O fato de um dente ter sido traumatizado pode influenciar no planejamento e no tratamento ortodôntico? E o protocolo das ativações do aparelho deveria ser alterado? O objetivo desse trabalho é apresentar uma breve revisão de literatura, bem como dois casos clínicos de pacientes que sofreram trauma dentário prévio à movimentação ortodôntica, no sentido de gerar subsídios técnicos e científicos para o especialista em Ortodontia, de modo que busque conhecer as implicações e limitações em movimentar dentes traumatizados.

Odontoma is a term that refers to a benign tumor of odontogenic and mixed nature, composed of epithelial and mesenchymal components. Histologically, they are compounds of different configurations including dental enamel, dentin, cementum and in some cases the pulp tissue. A slow growing asymptomatic tumor, odontoma is usually discovered through routine radiographic examination. A 3-year old male patient sought care at the School of Dentistry’s Baby Clinic (UNESP-Araçatuba), complaining of “small ball close to the teeth.” During the interview, the mother reported that the lesion was observed soon after a trauma, and evolved in less than one month. An ulcerated lesion with a 0.8 cm diameter was found during intraoral clinical examination. It was located in the inferior and anterior region of the mouth, between teeth 81 and 82, and there was also crown distalization. A radiographic examination showed a radiolucent area and root distance. In the absence of clinical and radiographic characteristics suggesting a case of odontoma, the differential diagnosis was peripheral giant cell lesion and pyogenic granuloma. So the area was punctured. Nonetheless, due to the absence of liquid, the surgical removal of the lesion was performed, followed by histological examination, which showed the definite diagnosis of a suggestive case of emerging odontoma.

Mucocele is a retention phenomenon from minor salivary gland caused by the excretory ducts rupture. This phenomenon may be caused by local trauma and its location is usually more frequent in the lower lip. Clinically, they appear as nodular lesions and may be exophytic and pedunculated. Histologically, this lesion can be classified as mucus extravasation phenomenon and mucus retention cyst. The treatments described in the literature are total lesion excision, marsupialization, cryosurgery, laser or micromarsupialização. To report a case of mucocele by mucus extravasation developed after a local trauma. A 7 years old Male was attended in the Pediatric Dentistry Clinic, Araçatuba School of Dentistry, complaining about the appearance of lesion in the lower lip since 40 days approximately. During clinical oral examination, it was observed that the lesion was pedunculated, nodular, fibrous to palpation, around 2 cm in diameter, similar in color to the surrounding mucosa, smoothly in surface, non-ulcerated and asymptomatic. As treatment, it was chosen the total lesion excision. Histopathology test confirmed the clinical diagnosis of: mucocele. Since mucocele is a frequent lesions in the oral cavity, it is extremely important that the professionals can to recognize this lesion (its pathogenesis and clinical features), to achieve a definitive diagnosis and perform an appropriate treatment.

The use of antimicrobial agents has facilitated the dissemination of multi-resistant microorganisms, compromising dental and medical treatment. The aim of this study was to evaluate the distribution of different opportunistic microbial species in patients who suffered head and neck trauma, under temporary maintenance in nosocomial environment, particularly intensive care units, on the occurrence of such microorganisms in the oral cavity of the patients. It was selected 38 patients subjected to head and neck traumas. After emergency surgical procedures, clinical samples of saliva, sub and supragingival biofilms and mucosal surfaces were collected at two different moments: just after stabilization of the patient and soon after patients’ release from medical units. The presence of opportunistic and superinfecting microorganisms was evaluated by culture on selective and non-selective media, and the presence of the family Enterobacteriaceae, as well as genera Enterococcus, Pseudomonas, and Staphylococcus was assessed by PCR. It was found that the use of antimicrobials, even for short periods of time was sufficient to facilitate colonization by microorganisms of the families Enterobacteriaceae and Pseudomonadaceae, as well as yeasts and enterococci. These results support the concept that medical and dental teams should make a periodically change of antimicrobials used in treatment protocols in hospital for head and neck trauma patients, in order to minimize dissemination of opportunistic or superinfecting microorganisms.

Objetivo: avaliar as alterações histológicas ocorridas na área periodontal de molares de ratos submetidos à movimentação dentária induzida (MDI), logo após um trauma intencional (subluxação). Métodos: quarenta ratos Wistar machos adultos (Rattus norvegicus albinus) foram selecionados. Os animais foram divididos em oito grupos (n = 5), de acordo com a combinação das variáveis: Grupo 1 – controle (sem trauma e sem MDI); Grupo 2 – MDI; Grupos 3, 4, 5 e 6 – grupos de trauma dentoalveolar correspondendo, respectivamente, para 1, 3, 8 e 10 dias após o trauma; Grupos 7 e 8 – os molares murinos foram submetidos a um impacto de 900cN e, de um e três dias após o evento trauma, o movimento do dente foi induzido. Os primeiros molares superiores dos animais foram movidos mesialmente durante sete dias, com uma mola fechada (50cN). Após período experimental de cada grupo, os animais foram sacrificados por overdose anestésica e as maxilas direitas foram removidas e processadas para análise histológica qualitativa. Resultados: nos animais dos grupos 3, 4, 5 e 6, as alterações histológicas não foram muito significativas. Consequentemente, o efeito do movimento dentário induzido logo após um evento de subluxação (grupos 7 e 8) foi muito semelhante ao descrito para o grupo 2. Conclusão: não houve diferença na qualidade do reparo periodontal quando a MDI foi aplicada aos dentes que sofreram um trauma de subluxação.

Objetivo: esta investigação tem como objetivo avaliar a prevalência de periodontite apical detectada na radiografia periapical e a relação entre a doença e a qualidade da obturação de canais radiculares realizada por estudantes de graduação. Métodos: foi investigada uma amostra aleatória de 131 prontuários de pacientes que haviam recebido tratamento do canal radicular na Faculdade de Odontologia de Araçatuba, Universidade Estadual Paulista. Realizou-se anamnese, radiografias e exame clínico quanto à sintomatologia dolorosa, presença e qualidade da restauração, bolsa periodontal, mobilidade dentária e trauma oclusal. Resultados: a porcentagem de sucesso obtido com o tratamento realizado pelos estudantes de graduação foi de 87,7%. Quando o tratamento foi adequado (43 casos), o percentual de sucesso foi de 90,69% (39 casos), enquanto para os tratamentos inadequados (14 casos), o percentual de sucesso foi de 78,57% (11 casos), sem diferença estatisticamente significativa (p>0,05). Não foi observada diferença estatisticamente significativa na taxa de sucesso relacionada ao sexo (p>0,05). A condição pulpar também não interferiu na taxa de sucesso (p>0,05). Conclusão: concluiu-se que o tratamento endodôntico foi satisfatório e alcançou uma taxa de sucesso adequada, em torno de 90% dos casos.
