ABSTRACT

INTRODUCTION: Laser applications have increased in a variety of dental procedures, especially in surgeries of soft tissues. Radiation is not invasive and is very well tolerated by tissues. CO2 laser acts in small vessels promoting blood coagulation, making it possible to work in a controlled way. Patients undergoing fixed orthodontic therapy often present injuries of gingival hyperplasia, originating esthetical and functional problems. OBJECTIVE: This study aimed at evaluating the CO2 laser effectiveness in removal of hyperplasia lesions in gingival papilla regions of patients with fixed orthodontic appliances. For this, ten patients were chosen and in these 75 teeth with gingival hyperplasia were identified. Measures from the papilla to incisal edge were performed with the use of a digital caliper. Besides that, the individuals were submitted to previous examinations to the surgical procedure with laser: Full blood count, blood coagulation profile and fasting blood glucose. After this, patients were submitted to the surgery for lesion removal, carried out at the Laser Center of FOUFBA, utilizing a CO2 laser machine (Sharplan 20C, Tel Aviv, Israel). RESULTS: It was showed that laser provided a significant increase (p<0,001) in the distance from the papilla to the incisal edge of the teeth, with no tissue contraction, aspects which were maintained for over two months. CONCLUSION: It can be concluded that CO2 laser has proved to be effective in removal of papillary gingival hyperplasia lesions.

ABSTRACT

A presença de acessórios nos aparelhos ortodônticos fixos favorece o acúmulo de biofilme bacteriano. Além disso, a negligência com a higiene bucal, por parte dos pacientes, faz com que a hiperplasia gengival ocorra com freqüência. O tratamento desta, além de gengivectomia convencional, pode ser realizado com laser de dióxido de carbono. Por um lado, as vantagens do uso deste laser são: proporcionar uma excelente hemostasia, resultante do vedamento de pequenos vasos sanguíneos, possibilitando uma excelente visualização do campo operatório; diminuição da concentração e formação de cicatrizes; redução do edema, da dor pós-operatória e da possibilidade de difusão de células anormais, devida ao vedamento de vasos linfáticos. Por outro lado, as desvantagens são o custo elevado, o tamanho do equipamento e a necessidade de pessoal especializado. Neste artigo, demonstrou-se as vantagens desta técnica na remoção de lesões de hiperplasia gengival em pacientes portadores de aparelho ortodôntico fixo.

ABSTRACT

INTRODUÇÃO: os modelos de estudo são fundamentais no diagnóstico e planejamento do tratamento ortodôntico, uma vez que, através deles, pode-se visualizar os arcos dentários em três dimensões. Além de servirem de referência para avaliação da condução do tratamento nas mais diferentes fases, são considerados uma das formas de registro legal. OBJETIVO: este artigo apresenta uma técnica de recorte, acabamento e polimento de modelos ortodônticos.


INTRODUCTION: Plaster cast models are fundamentals in the diagnosis and treatment planning in Orthodontics. The dental arches can be viewed in three dimensions and the models used as legal documentation for the orthodontist. AIM: Therefore, the object of this paper is to describe the technic of trimming and finishing the models.
