ABSTRACT

Diode laser with wavelengths ranging from 810 to 980 nm in a continuous or pulsed mode was used as a possible instrument for soft tissue surgery in the oral cavity. Diode laser is one of laser systems in which photons are produced by electric current with wavelengths of 810, 940 and 980nm. The application of diode laser in soft tissue oral surgery has been evaluated from a safety point of view, for facial pigmentation and vascular lesions and in oral surgery excision; for example frenectomy, epulis fissuratum and fibroma. The advantages of laser application are that it provides relatively bloodless surgical and post surgical courses with minimal swelling and scarring. We used diode laser for excisional biopsy of pyogenic granuloma and gingival pigmentation. The diode laser can be used as a modality for oral soft tissue surgery.

ABSTRACT

A reabsorção na maxila é, muitas vezes, um problema para a instalação de implantes osseointegráveis sem antes ter de fazer uso de enxertos ósseos ou cirurgias reconstrutivas. As cirurgias reconstrutivas em maxila são, com certeza, a opção mais indicada em casos de reabsorção severa. Nos casos onde as atrofias não são tão críticas, um dos artifícios que podem ser adotados é a utilização de expansores rosqueáveis, uma técnica mais conservadora e menos invasiva. Com a utilização dos expansores, o tecido ósseo é reposicionado, com fraturas do tipo galho verde e compactação óssea lateral, o que, além do ganho ósseo em espessura, propicia também uma melhor estabilidade primária. O objetivo deste trabalho é apresentar uma modificação da técnica de Summers, utilizando expansores ósseos rosqueáveis. Com o uso de expansores rosqueáveis, essa expansão e compactação lateral do tecido ósseo ocorre com maior controle e sem desconforto para o paciente, sendo a principal diferença da técnica proposta por Summers.


The maxillary bone resorption is often an obstacle when installing osseointegrated implants without previously using bone grafts and reconstructive surgeries. Maxillary reconstructive surgeries are definitely the most indicated option in cases of severe bone resorption. In cases where the atrophy is not so critical, one of the possible treatments is to use a expander screw, a much less invasive and more traditional technique. Using the expanders, we can relocate the bone tissue, through greenstick fractures and lateral bone compression, which makes the bone not only gain thickness, but also provides a better primary stability. The objective of this study is to present a modification of Summers technique, using a bone screw expanders. This expansion and compression of bone tissue, using screw expanders, helps to control the procedure, avoiding the patient feeling uncomfortable, unlike when using Summer's technique.

ABSTRACT

Oral submucous fibrosis (OSMF) is one of the most poorly understood and unsatisfactorily treated diseases. Various medical and surgical treatments have been used but with limited benefits. However, with advent of lasers, oral surgeons are provided with new modality for treating OSMF. This case report highlights the pioneering effort in treating a moderate case of bilateral OSMF with Erbium Chromium Yttrium Scandium Gallium Garnet (ErCr:YSGG) laser showing promising result during follow-up.

ABSTRACT

This paper reports the treatment of oral lymphangiomas with carbon dioxide CO2 Laser. Lymphangiomas are rare congenital lymphatic malformations. These lesions are most frequently diagnosed during childhood, are most commonly located in the head and neck region, and are extremely rare in the oral cavity. Oral lymphangiomas are of complex treatment due to the difficulty in performing a complete excision. CO2 laser is the most often used laser in the oral cavity due to its affinity with water and high absorption by the oral mucosa. Several benefits of the use of CO2 laser have been reported for surgical oral procedures. The cases reported herein were biopsy-proven lymphangiomas of the oral cavity. The surgical procedures were carried out under local anesthesia and a focused CO2 laser beam (l10.600 nm, f ~2 mm, CW/RSP) was used. At the end of the surgery, the laser beam was used on a defocused mode to promote better hemostasis. Neither sutures nor dressings were used after surgery. No medication and only mouthwashes were prescribed to all patients on the postoperative period. There were no postsurgical complaints from the patients and no relapses of the conditions were observed after follow-up periods of 12 and 18 months. The use of CO2 laser was practical, easy to carry out and effective on the treatment of oral lymphangiomas, with no lesion recurrence.


O objetivo deste trabalho é relatar o tratamento de linfangiomas orais com o laser de CO2. Os linfangiomas são raras malformações linfáticas congênitas que geralmente são diagnosticados na infância. São localizados preferencialmente na região de cabeça e pescoço, mas são extremamente raros na cavidade oral. As lesões da cavidade oral são de tratamento complexo, devido à dificuldade em exercer uma completa remoção. O laser de CO2 é o laser mais usado na cavidade oral devido à sua afinidade com a água e alta absorção pela mucosa oral. Diversos benefícios da utilização deste aparelho são relatados na literatura sobre a relação de procedimentos cirúrgicos realizados na cavidade oral. Os casos relatados são de linfangiomas comprovados por biópsia prévia. Os procedimentos cirúrgicos foram realizados sob anestesia local com um feixe de laser de CO2 no modo focado (20C Sharplan Laser Indústrias Israel, l10.600 nm, f ~2 mm, CW/RSP). Ao final da cirurgia foi utilizado um feixe de laser no modo desfocado, para promover uma melhor hemostasia. Nem suturas e curativos foram realizados após a cirurgia. Nenhuma medicação foi utilizada, somente anti-sépticos bucais foram prescritos para os pacientes no período pós-operatório. Não houve queixas no pós-operatório dos pacientes e nem recidivas após acompanhamentos de 12 e 18 meses. A utilização do laser de CO2 é um método prático, fácil e eficaz no tratamento de linfangiomas orais, sem recidiva nos períodos de acompanhamento.

ABSTRACT

The aim of this study was to compare the peripheral bone damage induced by different cutting systems. Four devices were tested: Er:YAG laser (2.94 mm), Piezosurgery, high-speed drill and low-speed drill. Forty-five bone sections, divided into 9 groups according to different parameters, were taken from pig mandibles within 1 h post mortem. Specimens were fixed in 10 percent buffered formalin, decalcified and cut in thin sections. Four different parameters were analyzed: cut precision, depth of incision, peripheral carbonization and presence of bone fragments. For statistical analysis, the Kruskal-Wallis test was applied to assess equality of sample medians among groups. All sections obtained with the Er:YAG laser showed poor peripheral carbonization. The edges of the incisions were always well-shaped and regular, no melting was observed. Piezosurgery specimens revealed superficial incisions without thermal damage but with irregular edges. The sections obtained by traditional drilling showed poor peripheral carbonization, especially if obtained at lower speed. There was statistically significant differences (p<0.01) among the cutting systems for all analyzed parameters. Er:YAG laser, gave poor peripheral carbonization, and may be considered an effective method in oral bone biopsies and permits to obtain clear and readable tissue specimens.


O objetivo deste estudo foi comparar o dano ósseo periférico produzido por diversos sistemas de corte. Foram avaliados 4 dispositivos: laser Er:YAG (2,94 mm), Piezo-cirurgia, broca em alta rotação e broca em baixa rotação. Para isto, foram utilizadas 45 seções ósseas retiradas de mandíbulas de suínos, até 1 h post-mortem, divididas em 9 grupos de acordo com diversos parâmetros. As amostras foram fixadas em formalina a 10 por cento tamponada, descalcificadas e cortadas em lâminas finas. Foram analisados 4 parâmetros diferentes: a precisão do corte, a profundidade da incisão, a carbonização periférica e presença de fragmentos ósseos. A análise estatística empregou o teste de Kruskal-Wallis para avaliar a similaridade das medianas entre os grupos. Todas as seções feitas com o laser Er:YAG exibiram pouca carbonização. As margens das incisões foram todas bem acabadas e regulares, sem apresentar pontos de fusão. As amostras obtidas por piezo-cirurgia apresentaram incisões superficiais sem danos térmicos, mas com margens irregulares. As seções obtidas pelas brocas convencionais apresentaram pouca carbonização marginal, particularmente as feitas em baixa rotação. Foram observadas diferenças estatisticamente significantes (p<0,01) entre todos os sistemas de corte para cada um dos parâmetros analisados. O laser Er:YAG apresentou pouca carbonização e pode ser considerado como um método eficaz para biópsias de ossos bucais, produzindo amostras de tecido limpas e fáceis de analisar.

ABSTRACT

La finalidad principal de este estudio fue mostrar las diferentes ventajas que presenta el uso de las suturas adhesivas (cianoacrilato) sobre las suturas convencionales (seda) en procedimientos en los cuales es necesario un cierre primario de heridas. Para ello se realizaron 6 incisiones tipo Neumman en 4 perros con el fin de comparar la reacción inflamatoria que mostraban los tejidos, al ser aplicado el adhesivo y la seda, y observar características clínicas de su confrontración de los bordes, hemostasia, tiempo de manipulación del procedimiento y retención de placa bacteriana. Los resultados mostraron que el uso de adhesivos es beneficioso como material de suturas en cavidad bucal, ya que presentó ventajas en el tiempo de manipulación, hemostasia conseguida en forma inmediata al ser aplicado, excelente confrontación de los bordes de las incisiones y nula retención de placa bacteriana
