Efeito da goma de mascar contendo sacarose e do dentifrício fluoretado na remineralização in situ de lesões de cárie artificiais

Abstract

The aim of this study was to evaluate the remineralization of incipient carious lesions in bovine enamel in situ. Artificial carious lesions were produced and fixed in removable lower appliances in the region of the lingual surfaces of first molars, in six volunteers with ages between 18 and 22 years, who were subjected to 3 distinct experimental periods of 1 week each. In the first period (control group), patients brushed their teeth with a non-fluoridated dentifrice 4 times a day (after meals), and, in the second period (group I), patients used a dentifrice containing 1,500 ppm of fluorine (in the form of MFP). In the third period (group II) volunteers brushed their teeth with non-fluoridated dentifrice and used chewing gum containing 60% of sucrose during 20 minutes, 4 times a day (after meals). Before and after each treatment, the specimens underwent Vicker's hardness test (200 g of load), and the remineralization percentage (alpha) was calculated. The control group showed 2.78% of demineralization, and groups I and II showed 3.36 and 5.21% of remineralization, respectively. Statistical analysis (with Kruskal-Wallis and Miller's tests) showed significant difference (p < 0.05) between the control and experimental groups (I and II). Group II showed greater alpha than group I, but this difference was not significant. These results suggest that the use of sucrose-containing chewing gum and fluoridated dentifrice has a considerable effect on the remineralization of incipient carious lesions and may be a valuable alternative for their prevention.

Sugar-free chewing gum and dental caries: a systematic review

“…Of the 16 excluded trials, 11 were not randomised 13 , 15 , 18 , 19 , 21 – 24 , 33 , 37 , 43 ; 3 trials 5 , 16 , 17 had a loss to follow up of more then 33% and 2 trials lacked operator blinding as part of their methodology 10 , 30 .…”

Effect of Sanguinaria canadensis Tincture Associated to a Chewing Gum on the Bacterial Biofilm

“…This increase in saliva may aid in the process of neutralization of acids produced by bacteria in the biofilm [13,[17][18][19][20]. Chewing gums increase the salivary flow, increasing the pH [13,19,[21][22][23][24][25][26][27], which leads to inhibition of formation of biofilm and its cariogenic potential [18,[23][24][25][26], besides aiding in dental remineralization [28][29][30].…”

Efeito de Diferentes Gomas de Mascar sobre o pH Salivar de Crianças

“…Assim sendo, fatores que aumentem o fluxo salivar e estimulem a mineralização têm efeito cárie-protetor. Nesse sentido, foi relatada a importância da estimulação do fluxo salivar em programas de prevenção da cárie dentária com a utilização de gomas de mascar 19 . Neste trabalho, pôde-se perceber claramente pelos resultados apresentados que o uso da goma de mascar provocou uma acentuada elevação no pH salivar perceptível na terceira coleta (T5) independentemente do método utilizado para sua aferição, após 5 min do seu uso e descarte.…”
