摘要: AIM The purpose of this pilot study was to identify the subsurface enamel demineralising potential two possible acidogenic lactose-based powders and their corresponding generic pump inhalers. METHODS Ten healthy non-asthmatic adults participated in a 5- leg randomised crossover including 10% sucrose control. A twice-daily 400 microg dose inhaler applied vitro demineralised slab on buccal flange mandibular removable appliance before situ placement for 14 days each. Lesion parameters were determined using transverse microradiography digitised image analysis. RESULTS Minimal demineralisation occurred with sucrose, both one powder inhaler. remaining associated remineralisation (p = 0.29). Overall, mean lesion depth increased 0.12). CONCLUSION Asthma inhalers failed demonstrate significant acidogenic/cariogenic effect.
