The aim of the present study is to assess the remineralizing effect of Er,Cr:YSGG laser application combined with CPP-ACPF after erosive demineralization by Coca-Cola in primary teeth and to weigh against the most effective timing Er,Cr:YSGG laser application i.e. before or after CPP-ACFP application. Fifty sound primary teeth (exfoliated/extracted for orthodontic reasons) with initial DIANOdent (DD) reading {u2264} 5 were divided into 5 groups (n=10); Group I: Artificial saliva, (Saliva natura, Medac, UK), Group II: CPP-ACPF (MI paste Plus, GC Corp, USA), Group III: Er,Cr:YSGG (Waterlase iPlus, USA), Group IV: CPP-ACPF + Er,Cr:YSGG, Group V: Er,Cr:YSGG + CPP-ACPF.Teeth were immersed in 20 ml of Coca-Cola for 10 min, 5 times/day with 3 hours interval (9 am,12 pm, 3 pm, 6 pm and 9 pm) for 5 days. CPP-ACPF paste was applied to teeth in groups II, IV and V. a sufficient amount of paste was smeared evenly on all tooth surfaces using a brush and left undisturbed for 5 minutes. As recommended, the paste was applied twice per day; before the first erosive challenge and after the last one UR - http://172.23.153.220/th.pdf ER -
