Resumo(s)
Os açúcares não fermentáveis como o xilitol são de grande interesse para a medicina dentária na prevenção da cárie, por serem descritos como agentes não cariogénicos. O xilitol é um açúcar de substituição, nomeadamente, um poliol com cinco átomos de carbono e cinco grupos hidroxilo, de estrutura cristalina, encontrado em muitas frutas e vegetais. O xilitol tem sido utilizado em medicina dentária, no controlo da atividade cariogénica, sobretudo administrado na forma de pastilha elástica. O objetivo deste trabalho é realizar uma revisão narrativa da literatura sobre o uso das pastilhas elásticas de xilitol na prevenção da cárie dentária. Foi realizada uma pesquisa eletrónica nas bases de dados PubMed e Google Scholar, tendo sido considerados artigos científicos em língua portuguesa, inglesa e espanhola. Em acréscimo, foram analisados artigos identificados manualmente por serem referenciados na bibliografia dos artigos e livros previamente consultados. A pastilha elástica, forma de administração do xilitol mais comummente usada, alia a capacidade não cariogénica deste e o ato de mastigar a pastilha elástica, um potente estimulador do fluxo salivar, resultando no aumento da capacidade tampão e a limpeza da cavidade oral. Um dos efeitos secundários indesejável é o efeito laxante, associado a uma maior dose da substância e verificado apenas em alguns indivíduos. No entanto, a evidência científica dos estudos realizados com pastilhas elásticas de xilitol sobre o tema é limitada.
Non-fermentable sugars such as xylitol are of great interest to dental medicine in preventing caries because they are described as non-cariogenic agents. Xylitol is a sugar of substitution, namely, a polyol of five carbon atoms and five hydroxyl groups, of crystalline structure, found in many fruits and vegetables. Xylitol has been used in dental medicine to control cariogenic activity, mainly administered as a chewing gum. The objective of this work is to conduct a narrative review of the literature on the use of xylitol chewing gum in the prevention of dental caries. An electronic research was carried out in the PubMed and Google Scholar databases, being considered scientific articles in Portuguese, English and Spanish. In addition, manually identified articles were analyzed because they were referenced in the bibliography of previously consulted articles and books. The chewing gum, the most commonly used form of xylitol, combines the non-cariogenic capacity of the latter and the act of chewing, a potent salivary flow stimulator, resulting in increased buffer capacity and oral cavity cleansing. One of the undesirable side effects is the laxative effect, associated with a higher dose of the substance and in some individuals. However, the scientific evidence of the studies carried out with xylitol chewing gum on the subject is limited.
