Aim: The aim of the present study is to evaluate and compare the subjective acceptance in children during hard dental tissue therapy using Er:YAG laser 2940nm and conventional rotary instruments.
Methods and materials: The study included ninety 6-12-years-old children with matched carious lesions (D3 threshold, WHO system), divided into two equal treatment groups. In the intervention group the cavities were prepared with Erbium:YAG laser 2940nm and in the control group with conventional rotary instruments, without anaesthesia. After cavity preparation patient’s subjective acceptance was assessed by a questionnaire concerning primary stress triggers.
Results: The annoyance factor (vibration) was found as a stress trigger in the majority of control children (86.7%), while in the intervention group it was found in 2.2% of cases. The most anxiety provoking items in the intervention group were smell (67.7%) and taste (42.2%). The sound was found to be a stress trigger in more than half of control children (62.2%) and less than one-fifth of the children in the intervention group (15.6%). The study results showed significant difference in these items between two groups (p< 0.001).
Conclusions: The Erbium:YAG lasers reduce three of four stress triggers in `4S` principle - vibration, sight and sound. They are a good treatment option for fearful children since they have acceptable efficiency in treatment of pediatric anxiety disorders compared to the mechanical preparation.
