Abstract:The wound healing process has always been an excellent subject for researchers. The use of lowpower laser on wounds during the postoperative phase has increased the speed of the healing process. It has been implied that low power radiation affects cellular metabolic processes and promotes beneficial biological effects (analgesic, anti-inflammatory, and healing). Laser biostimulation appears to influence the behavior of the repair process. This paper aims at reviewing the most interesting aspects of the use of lowpower laser in the tissue-repair process. Key words: lasers, low-level laser therapy, wound healing Resumo: Os lasers de baixa potência promovem efeitos biológicos benéficos, de caráter analgésico, antiinflamatório e cicatrizante, por meio de um fenômeno de bioestimulação. A radiação emitida pelo laser terapêutico afeta os processos metabólicos das células-alvo, produzindo efeitos bioestimulantes que resultam na ocorrência de eventos celulares e vasculares, os quais parecem interferir diretamente no processo de reparo. Este trabalho visa estudar o fenômeno da bioestimulação e destacar os principais efeitos bioestimulantes do laser de baixa potência na reparação tecidual. Palavras-chave: Cicatrização de feridas; Lasers; Terapia a laser de baixa intensidade
Objective: To evaluate the metabolic control and compare the clinical effects between non-surgical and surgical therapies on periodontal treatment of residual pockets of type 2 diabetic patients. Material and Methods: 352 periodontal sites in 16 type 2 diabetic subjects with residual pockets of similar depths were randomly selected, whose contralateral quadrants were divided into G1 and G2 undergoing surgical and nonsurgical therapy, respectively, and evaluated 3 and 6 months after the first intervention. The data were analyzed by Statistical Package of Social Science (SPSS) version 20.0, using descriptive and inferential statistical methods. Fisher's exact test was used to verify differences between means obtained in the clinical parameters between G1 and G2. The significance level adopted was 5%. Results: The mean Hb1Ac values of patients were significantly reduced and the mean PD and CIL values were reduced in G1 with no significant difference when compared to G2. Conclusion: Periodontal treatment was effective in metabolic control of type 2 diabetic patients and that both therapies, surgical and non-surgical, behaved similarly when compared.
O objetivo deste estudo foi avaliar o nível de conhecimento sobre recessão gengival por parte de alunos e professores de uma clínica escola do curso de Odontologia de uma instituição privada de ensino. Esta é uma pesquisa quantitativa, transversal e exploratória. Foi aplicado um questionário semiestruturado com perguntas objetivas. Dentre os entrevistados, 100% afirmaram conhecer o que era retração gengival; Apenas 48,54% dos alunos e 15,38% dos professores relatam conhecer a classificação de Miller. A conduta clínica adotada pelos entrevistados se mostrou coerente e o resultado satisfatório, uma vez que a maioria das respostas obtidas foi condizente ao esperado quanto à recessão gengival.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
