Isotonic solutions can generate tooth erosion, make the dental structure more fragile and enhance tooth wear. The aim of the present study is to assess dental resistance to fracture after exposure to isotonic drinks. An in vitro study was carried out with human teeth, which were divided into a test group and a control group. Two main stages were developed: in the first stage, the erosive potential of isotonic drinks was analyzed and, in the second stage, the analysis of resistance to dental fracture was performed, based on the mechanical test. The isotonic drinks had low pH (hydrogen potential) values, indicating high acidity and the isotonic lemon flavor had a higher value for TA (Titratable Acidity). Regarding the analysis of fracture resistance, the samples in the test group showed less resistance to dental fracture than the samples in the control group and the specimens in the test group that remained longer in isotonic drinks showed greater structural fragility. This study showed that the longer the exposure to the erosive challenge, the more susceptible to fracture the dental element is, due to the wear of the enamel structure caused by the isotonic. | Keywords : | | Athletes; Isotonic solutions; Sports; Tooth erosion; Tooth wear
