Evaluation of care of dentoalveolar trauma.

OBJECTIVES: The aim of this study was to evaluate cases of dental trauma treated at the specialized center of Pontifical Catholic University of Paraná, Curitiba, Brazil, during a period of 2 years. MATERIAL AND METHODS: A total of 647 patients were evaluated and treated between 2003 and 2005. Data obtained from each patient were tabulated and analyzed as to gender, age, etiology, time elapsed after the injury, diagnosis (type of trauma), and affected teeth. RESULTS: The results revealed that male individuals aged 7 to 13 years presented the highest prevalence of injury, and falling was the main causal factor. In most cases, the time elapsed between the accident and the first care ranged from 4 to 24 h. A total of 1,747 teeth were affected, with higher incidence of concussion/subluxation and coronal fracture, followed by lateral luxation and avulsion. The permanent maxillary central incisors were the most commonly affected teeth. CONCLUSION: The frequency and causes of dentoalveolar trauma should be investigated for identification of risk groups, treatment demands and costs in order to allow for the establishment of effective preventive measures that can reduce the treatment duration and costs for both patients and oral health services.

Estudo in vitro da infiltração marginal apical de canais obturados pela técnica termomecânica híbrida com e sem a remoção do smear layer / An in vitro evaluation of apicalleakage of technique hybrid thermomechanic endodontics obturation with and without the removal of the smear layer

No presente estudo, foi avaliado, in vitro, o selamento apical de canais obturados pela técnica híbrida após a utilização da solução quelante EDTA. Doze caninos superiores foram divididos em dois grupos onde se variou a substância auxiliar do preparo biomecânico, a saber; hipoclorito de sódio a 0,5% e hipoclorito de sódio a 0,5% seguido de irrigação final com a solução de EDT A, utilizou-se um dente para o controle negativo e um para o controle positivo. Para a obturação dos canais radiculares foi utilizado o cimento obturador Sealer 26@ (Dentsply). Após a obturação, os dentes foram imersos em tinta nankin e mantidos em recipientes a 37° C por um período de 96 horas. Após este, os dentes foram lavados em água corrente e submetidos à descalcificação com ácido clorídrico a 5% e depois lavados novamente e desidratados em bateria de álcool ascendente. A seguir os dentes foram diafanizados em salicilato de metila. Obtida a diafanização dos dentes, a infiltração marginal apical foi quantificada por meio do uso de um microscópio de mensuração. Os resultados obtidos evidenciaram que os dois grupos permitiram infiltração marginal apical, porém os resultados estatísticos mostra-ram que o grupo onde se utilizou a solução de EDT A apresentou uma infiltração marginal apical significativamente menor (p

Banco de dentes: ética e legalidade no ensino, pesquisa e tratamento odontológico / Teeth bank: ethic and legality in teaching, research and dentistry treatment

Este artigo apresenta à classe profissional os passos para a criaçäo de bancos de dentes junto a instituiçöes de ensino, destacando aspectos importantes de seu funcionamento e sua funçäo social. Divulga as diretrizes legais a que dentes humanos estäo sujeitos e suas implicaçöes éticas. Salienta a importância destes bancos para coibir o comércio ilegal deste órgäo humano e a biossegurança no manuseio destes órgäos corretamente processados

Intentional replantation with 180 degrees rotation of a crown-root fracture: a case report.

Crown root fractures are frequently difficult to treat and have a bad prognosis. To restore the biological space, intentional replantation can be chosen when osteotomy/osteoplasty and dental traction are not viable. Intentional replantation with tooth rotation consists of extraction, 180 degrees rotation and replantation, thus restoring the biological space. After treatment of inflammatory resorption with calcium hydroxide, endodontic treatment was completed. The patient was followed up with clinical examination (mobility test, gingival sulcus depth) and radiographic analysis (to analyze root resorption: inflammatory and/or substitution, and the integrity of the alveolar cortex and the periodontal space) for 3 years and there were no signs of resorption.
