ABSTRACT

20 children aged 3 years ±3 months with dental caries were randomly divided into 2 groups(n =1 0).The caries tissue was re-moved by conventional bur and ErYAG laser respectively without the use of mouth speculum,mouth gag and binding belts.In laser group the success rate of treatment at first visit and return visit was higher(P <0.05)and children's dental anxiety grad was lower(P <0.05).The ErYAG laser is more effective in easing children's dental anxiety and in the dental treatment.
