COBOS ORTEGA, Cinthya; VALENZUELA ESPINOZA, Emilia  and  ARAIZA, Miguel Ángel. Influence exerted by a xylitol and fluoride based mouthwash on the in vitro enamel remineralization of primary teeth. Rev. Odont. Mex [online]. 2013, vol.17, n.4, pp.204-209. ISSN 1870-199X.

The purpose of the present study was to assess the effectiveness on primary teeth of a fluoride and xylitol based mouthwash. 40 caries-free teeth were used. 35% phosphoric acid was applied during 20 seconds. Teeth were then immersed in the mouthwash for 0, 15, 30, 45 and 60 days. 150-250μm longitudinal slices were taken of each sample. Re-mineralization was assessed according to bi-refringence observed after applying Thoulet solution (1.47 IR). Assessment was conducted under polarized light in a photo-microscope. At 15 days, a mean of 0.444 (± 0.527) was observed. After 30 days the observed mean was 0.778 (± 0.441). At 45 days, observed mean was 1.444 (± 0.527), and at 60 days, observed mean was 1.47 (± 0.483). Variance analysis established statistically significant differences among groups (p < 0.001) as well as when comparisons among groups were established (p < 0.05). After conducting the aforementioned tests it could be concluded that the employed mouthwash exerted a slight re-mineralizing effect upon the enamel of treated teeth.
