Remineralizing potential of a 60‐s in vitro application of Tooth Mousse Plus

Background No published studies exist on the remineralizing potential of Tooth Mousse Plus ® ( TMP ) when applied for less than 3 min. Aim To evaluate (i) the remineralizing potential of TMP on artificial carious lesions, when applied thrice daily for 60 s, and (ii) the benefit of using a fluoridated dentifrice prior to TMP application. Design Carious lesions, 120–200 μ m deep, were produced by placing molars in demineralizing solution for 96 h, and sections 100–150 μ m thick were then randomly assigned to four groups. Specimens were treated thrice daily with a non‐fluoridated (Group A), or 1000 ppm F dentifrice (Group B), or TMP (Group C), or a 1000 ppm F dentifrice followed by TMP application (Group D), and then subjected to a 10‐day pH cycling model. Lesion evaluation involved polarizing light microscopy and microradiography. Results Post‐treatment maximum mineral content at the surface zone ( V max ) was significantly increased and lesion depth ( LD ) significantly decreased in Group C, while only the V max increased in Group D. Increase in LD was observed in Group B; however, no significant differences were noted in percentage LD changes between groups B, C, and D ( P > 0.05). Conclusions TMP applied for 60 s significantly remineralized the artificial carious lesions. No additional benefit was evident when TMP was preceded by treatment with 1000 ppm F dentifrice.
