ABSTRACT
The Gorlin-Goltz syndrome, nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome is an autosomal dominant condition disorder with high variability expression. It presents a series of relevant clinical manifestations that suggest its diagnosis in cutaneous, bone, dental, soft tissue, nervous, and ocular system disorders. This condition requires a great interaction of several specialists to improve the patient's life. In this case, we presented a 9-year-old male patient referred to the Department of Oral and Maxillofacial Surgery reporting failure in the normal chronology of dental eruption. After evaluation, it was observed that the patient had 13 typical characteristics of the syndrome, including keratocysts, bifid ribs, palmoplantar pits, and 10 other minor characteristics. In conclusion, the expression of so many features of Gorlin-Goltz syndrome is rare in infants, and early diagnosis is important to decrease morbidity and mortality associated with basal cell carcinomas.
ABSTRACT
PURPOSE: The aim of this study was to evaluate the effects of LED and low-intensity laser on the healing of rabbit dental alveoli. METHODS: A total of 18 rabbits were divided into three groups of six; all rabbits underwent surgical extraction of the first lower right premolar. Following surgery, group 1 received LED irradiation, group 2 received laser irradiation, and group 3 were untreated controls. The initial applications of LED and laser began 48 h after tooth extraction and were given perpendicularly to the dental alveoli. The three groups were clinically evaluated for 18 days in the postoperative period. At 90 days, the rabbits were euthanized and the mandibular fragments containing the healing alveoli were collected. These fragments initially underwent computed tomography scans and bone density was measured in Hounsfield units. Following this, the fragments were processed and stained with hematoxylin and eosin for histological and histomorphometric analysis. RESULTS: The results were compatible between the clinical, histological, and histomorphometric parameters evaluated. There were no statistical differences between the LED and laser groups. However, the difference of the average bone density between laser and control group was not statistically significant. CONCLUSIONS: It was found that photobiomodulation with LASER and LED presented effects. However, only the LED demonstrated a beneficial effect on the process of bone repair in the dental alveoli of rabbits.

Oral Myiasis is a rare pathology in humans and is associated with poor oral hygiene, alcoholism, senility, suppurating lesions, severe halitosis and others conditions. The treatment is a mechanical removal of the maggots one by one but a systemic treatment with Ivermectin, a semi-synthetic macrolide antibiotic, have been used for treatment for oral myiasis. We present a case report of a 32-year-old man indigent, alcohol-dependent with an extensive necrotic area and acute swelling in upper lip and fetid odor. The patient's management included topic use of gentian violet, oral therapy with ivermectin (6 mg orally), surgical exploration to remove the larvae and necrotic tissue. After the complete larvae removal the swelling and the wounds were healing normally, the patients was referred to plastic surgery to repair tissue damage. The prevention of human myiasis is by education, but unfortunately in the developing countries some people live in low social condition, predisposing the occurrence of the infestation.

O trauma de face tem sido o objetivo de uma série de pesquisas e levantamentos estatísticos em diversos hospitais do mundo. Resultados semelhantes foram encontrados, mesmos em países com diferentes situações culturais e sócio-econõmicas. O presente trabalho consistiu-se em desenvolver um levantamento de todos os pacientes com trauma facial atendidos pelos alunos do curso de Especialização em Cirurgia e Traumatologia Buco-Maxilo-Facial da Faculdade de Odontologia da UFMG, no Pronto Socorro do Hospital Municipal Odilon Behrens de Belo Horizonte no período de novembro de 1997 a julho de 1999. Neste levantamento, foram avaliados no paciente: o sexo, a faixa etária, o fator etiológico e o tipo de atendimento realizado.

Os autores estudaram "in vitro" dois fatores que podem ser responsáveis pelo insucesso na modalidade cirúrgica apicectomia com obturaçäo retrógrada: a infiltraçäo marginal e a permeabilidade da dentina radicular. Foram utilizados 32 dentes humanos, recém-extraídos, divididos em dois grupos. No grupo I, os dentes foram obturados com amálgama de prata e, no grupo II, os dentes foram obturados com pasta de óxido de zinco-eugenol para moldagens e empregado como corante o azul de metileno a 2 por cento, com ph 7,2, por 7 dias, a temperatura de 37ºC. Os resultados obtidos, através das inspeçöes em lupa estereoscópica levaram a conclusäo de que somente no Grupo II näo ocorreu infiltraçäo marginal

Em nosso trabalho testamos a capacidade de vedamento da Pasta Lysanda em retrobturações, usando como parâmetro de comparação retrobturações com amálgama de prata. As retrobturações foram feitas em incisivos superiores de 10 cães e proservadas por 30 dias. Após este período, os cães foram sacrificados, seus dentes incisivos maxilares extraídos e imersos em corante azul de metileno por uma semana, quando então foram seccionados ao meio longitudinalmente e avaliados quanto a infiltração marginal do corante retrobturações. Obtivemos como resultado que todos os dentes retrobturados com amálgama de prata mostraram grau de infiltração intenso, enquanto os retrobturados com Pasta Lysanda, mostraram infiltração ausente em oito dentes e leve em seis dentes

A proposta do presente trabalho foi estudar a eficácia da impermeabilizaçäo de alguns materiais impermeabilizantes utilizados na avaliaçäo de infiltraçäo marginal. Foram utilizados 40 dentes pre-molares íntegros superiores e inferiores, recém-extraídos e submetidos a impermeabilizaçäo com esmalte para unhas e resina epóxi. As amostras foram imersas durante 7 dias em soluçäo de Azul de Metileno a 2 por cento, com pH7,2, em uma temperatura de 37ºC. Os resultados obtidos através da inspecçäo em lupa estereoscópica levaram a conclusäo de que somente a associaçäo de uma camada de resina epóxi, seguida de uma camada de esmalte para unhas näo permitiu a penetrabilidade da soluçäo corante indicadora
