Purpose of this monograph is a critical review of articles and publications worldwide. The insertion of green chemistry concepts in the curriculum components of general chemistry lab, plays a fundamental role in the early years of a Chemistry course towards early embed the philosophy of green chemistry. The fundamental concepts of green chemistry are highlighted in order to present the huge number of challenges in developing new chemistry l in research, industry and education. The practice of a chemical that takes into account ethical environmental attitudes thought since the formation of professionals, may lead to adoption of technical microscale, replacement of toxic agents, reduction of waste generation, etc. who snore a lot with the concept of sustainability

The majority of published papers deal mainly with prevalence, pathogenesis and treatment of squamous cell carcinoma of the gingiva (SCCG). On the other hand, little is discussed about the comparison between periodontal disease and gingival carcinoma with emphasis on radiographic imaging. In this case report we discuss the importance of the radiographic aspects in inflammatory periodontal disease and SCCG. This case report shows the importance of differentiating a localized severe periodontal disease and SCCG considering the radiographic aspects of the inflammatory bone loss and tumoral bone loss. The oral health care providers need to be familiar with the radiographic imaging of periodontal disease and SCCG.

The aim of this study was to relate the clinical case of a patient with oral lichen planus (OLP) and a history of epidermoid carcinoma associated with metallic restorations. The etiology of OLP is a mucocutaneous disease, which is poorly understood. Studies point to the potential of malignant transformation of OLP and its association with metallic restorations. The metallic restorations were replaced by crowns with a ceramic covering associated and osseointegrated implants in the edentulous areas. About 1 year later, it was observed a bilateral regression of the tongue lesions. The replacement of metallic restorations can contribute to improvement of OLP.

O carcinoma espinocelular é uma das quatro neoplasias malignas que mais acomete gatos, principalmente os de pele clara e que residem em países tropicais onde a incidência de raios solares é intensa. O tratamento cirúrgico é o mais indicado, mas nem sempre é possível de ser realizado seja pelo estágio avançado do tumor, pela sua localização ou por opção do proprietário que não quer ver seu animal mutilado. O objetivo desta revisão sistemática foi verificar a eficácia da quimioterapia com ou sem associações terapêuticas para o tratamento do carcinoma espinocelular superficial, multicêntrico e de cabeça e pescoço em gatos. Os melhores resultados para o tratamento do carcinoma espinocelular superficial foram observados com a aplicação intralesional do quimioterápico associado à radioterapia ou à eletroterapia, para o tipo multicêntrico faltam trabalhos sobre o assunto e o único encontrado não apresentou resultados satisfatórios. No caso do carcinoma espinocelular de cabeça e pescoço que alberga o pior prognóstico, a terapia multimodal com associação de quimioterapia, radioterapia e excisão cirúrgica demonstrou ser eficiente. Mais estudos sobre o assunto devem ser realizados utilizando um número maior de animais e com um tempo de seguimento mais longo

The purpose was to evaluate the effectiveness of beta-radiation with strontium-90 as single modality treatment of canine third eyelid squamous cell carcinoma (SCC). Nine dogs diagnosed with third eyelid SCC were treated with strontium-90. Radiation therapy was administered in four fractions of 100cGy per site every four days and at a depth of 0.2cm (Strontium-90 build' up) in each fraction. Radiation with beta therapy was well tolerated in all animals with no occurrence of radiation induced cataracts. In all cases, there were increased signs of conjunctival inflammation around the mass, which subsided with topical anti-inflammatory. Two dogs required surgical treatment for local tumor recurrence at 150 days and 352 days. In the remaining seven cases, disease free interval ranged from 1239 days to 2555 days. Beta therapy using 90Sr may be a valid alternative for the treatment of third eyelid SCC in dogs
