This study aimed to evaluate the laser therapy efficacy in paediatric dentistry, considering the subjective tolerance and
acceptance of therapy in children needing both dental and soft tissue treatments.
A group of 50 patients from 6 to 12 years
of age, needing both hard and soft tissue therapy was selected and treated, without anesthesia, with an Er,Cr:YSGG laser 2780 nm and
an Er:YAG laser 2940 nm for a total of 100 treatments performed; before and after the treatment the patients experience was tested
with Wong-Baker modified facial image scale.
The study showed a good percentage of acceptance and tolerance of both
laser treatments: a success rate of 90 for hard tissues and 63 for soft tissues was obtained; for the total 100
treatments the acceptance was of 75.
The Erbium lasers are very effective in paediatric dentistry and are good
