RESUMO
A infraoclusão de molares decíduos é uma situação clínica que pode causar prejuízos ao desenvolvimento da oclusão do paciente, mas com o desenvolvimento das técnicas e materiais odontológicos nos últimos anos, esse quadro clínico pode ser solucionado através de uma terapia mais conservadora. Este trabalho tem como objetivo apresentar a reabilitação de um dente em infraoclusão através da utilização de uma restauração indireta em resina composta. Esta técnica permite restabelecer as dimensões anatômicas, o equilíbrio oclusal e a estética da criança. Ao final pôde-se concluir que as restaurações indiretas em resina são uma boa opção de tratamento conservador para os casos de infraoclusão na dentição decídua.
Infraoccluded primary molars is a common clinical situation that can cause several damages for the development of occlusion, but with today?s development of the techniques and dental materials these clinical situation has several ways to be resolved, returning the oclusal balance for the patient. This article had as aim present a clinical report of a rehabilitation of an infraoccluded primary molar with the use of an indirect restoration in composite resin, designed to restore the anatomical size, the occlusion and esthetics of the child. At the end we can conclude that this technique presents several advantages, especially in Pediatric Dentistry.
RESUMO
O objetivo deste trabalho foi avaliar ao efeito citotóxico doHidróxido de Cálcio, Paramonoclorofenol Canforado, Otosporin eFormocresol diluído em células-tronco da polpa de dente permanentehumano (DPSC). As DPSC foram semeadas em placa decultura na concentração de 1,5X104 células/poço. Foram feitasdiluições das drogas em 1:9, 1:27 e 1:81 e deixadas em contatocom as células por 2 horas, sendo que o grupo controle foi mantidoem DMEM completo. As células foram lavadas com soluçãosalina duas vezes. Foram realizadas avaliações do metabolismo(MTT). Concluiu-se que o Hidróxido de Cálcio e o Otosporinforam as drogas menos tóxicas para as DPSC, enquanto que oParamonofenol Canforado e o Formocresol foram letais em todas asconcentrações.
The aim of this paper was analyze the cytotoxicity effect ofCalcium Hydroxide, Paramonoclorofenol Canforado, Otosporinand Formocresol deluded in dental pulp stem cells (DPSC).Material and Methods: DPSC were grown in 96 wells cultureplate in the concentration of 1.5 X104 cells per well. Dilutionsof drugs were as followed: 1:9, 1:27 and 1:81, and control withDPSC in DMEM. The cells were cultured for an additional 2hours. The cells were washed with bufferin saline solution for2 times and MTT test was performed. Results: The Ca(OH)2and Otosporin were the drugs less toxic to the DPSC, while theParamonophenol Canforated and formocresol were lethal in allconcentrations. Conclusions: all drugs tested were toxic to theDPSC.
RESUMO
Periodontitis is a chronic disease characterized by bone loss and inflammatory changes. We studied the effect of a homeopathic agent (Mercúrios Corrosivos 6 CH) and a non-steroidal anti-inflammatory drug (nimesulide) on the alveolar bone loss progression in experimentally induced periodontitis in rats. Sixty (60) Wistar rats were separated into group 1 (homeopathy), group 2 (nimesulide) and group 3 (saline solution). Silk ligatures were placed at the gingival margin level of the lower right first molar of all rats. Alveolar bone loss was evaluated by light microscopic analysis and analyzed using software Image J. The results were submitted to the analysis of variance (ANOVA) and Tukeys posttest (p<0.05). The analysis revealed that there was a higher bone loss in diseased sites as compared with healthy sites. A significant reduction in the alveolar bone resorption was observed in group 2 (nimesulide) as compared with group 1 (homeopathy) 7 days after the induction of periodontitis. Our data provided evidence that homeopathy does not decrease alveolar bone loss as opposed to nimesulide in experimentally induced periodontitis.
