Objective: This study was performed to evaluate the effect of three remineralizing agents' (Curodont repair, Clinpro XT varnish, and Clinpro white varnish) application on the state and shade of white spot.
Materials and methods: Twenty patients were included in this study. The state and shade of white spot lesions before the application of the remineralizing agents were assessed using two devices, which are the Diagnodent Pen and Vita easyshade V. The affected nearest right tooth to the midline was treated with Curodont™ Repair, while the affected nearest left tooth to the midline was treated using Clinpro™ XT Varnish, and the third right or left affected tooth was treated using Clinpro white varnish (3M ESPE Dental). After the application, each white spot lesion of the treated tooth was evaluated immediately, after three months and after six months.
Results: Both Curodont™ Repair and Clinpro™ XT Varnish showed significant improvement in the state (p < 0.001) and shade (p < 0.001) of the lesions after application, both immediately and after three and six months, with no significant difference between the effect of both treatments (p=0.140 and p=0.985 respectively). Clinpro white varnish showed no significant improvement in the state and shade after application, immediately or after three and six months.
Conclusion: Curodont™ Repair and Clinpro™ XT Varnish showed significant improvement in the progression white spot lesions. Clinpro white varnish showed no significant effect.
