Evaluating the protective effects of mouthguards with neutralizing agents against chlorinated water-induced enamel erosion

Mouthguards significantly reduced enamel microhardness loss compared to no mouthguard use. While no significant differences were found among mouthguard groups with or without neutralizing agents, those lined with arginine-fluoride toothpaste showed the least enamel loss, suggesting its potential protective effect. Within the limitations of this <i>in vitro</i> study, further clinical trials are needed to validate these results.
