Título: o cigarro eletrônico e seus efeitos na saúde bucal – revisão de literatura

Abstract

Electronic cigarettes emerged in China in 2003 as an option for smoking cessation. Currently, its use is increasing among teenagers and young adults, being considered as a gateway to the use of conventional cigarettes. However, unlike conventional cigarettes, the effects of electronic cigarettes on oral health are not well known. The objective of this study was to carry out a critical and updated review of the composition of electronic cigarettes and the effects on oral health related to the use of this device. A search was carried out for scientific articles in the PubMed (Medline), Scopus and Periodicos Capes databases, using the terms: electronic nicotine delivery systems and oral health OR electronic cigarettes and oral health OR e-cigarettes and oral health. Regarding the composition, it was possible to observe that propylene glycol, vegetable glycerin, flavorings, heavy metals and nicotine are present in most e-liquids. The main effects on oral heath found were related to the periodontium. There seems to be less damage to oral health when conventional cigarettes are replaced by electronic cigarettes. Considering that e-cigarettes are relatively new devices, the long-term effects are not yet possible to assess. In addition, the lack of regulation regarding composition makes it difficult to analyze the results presented in the literature so far. Therefore, more studies are needed to assess the real effects of electronic cigarettes on oral health.
