To apply erbium-doped yttrium aluminium garnet laser to the closure of young permanent teeth and pits, compare the total retention rate of sealants, and discuss whether erbium-doped yttrium aluminium garnet laser is suitable for clinical treatment in children. Sixty children with 6-9 y old and bilateral mandibular first molars with complicated sulcus were randomly divided into two groups: A and B. The self-half control method was used: group A children’s control side test teeth application of corundum The enamel was performed by enamel, acid etching, coating pit and fissure sealant, erbium-doped yttrium aluminium garnet laser enameloplasty was applied to the contralateral test teeth and pit and fissure sealant was applied; group B children’s control side test teeth were treated with group A. The contralateral test teeth were treated with erbium-doped yttrium aluminium garnet laser enameloplasty, acid etching, and coating pit and fissure sealant. The children were scored for treatment after surgery, and regular follow-up was performed to observe the retention of the sealant. 63.3 % of the children tested were willing to take the initiative to choose laser treatment. At the 3rd and 6th mo of follow-up, there was no significant difference in the total retention rate of the two groups of sealants (p>0.05); at the 12th and 18th mos of followup, the total retention rate of the sealant materials: laser+etchant group>traditional bur. The difference between the needle group and the laser group was statistically significant (p<0.05). Laser is a more acceptable treatment for children. Erbium-doped yttrium aluminium garnet laser is used in the formation of permanent enamel. It needs to be combined with acid etchant to enhance the retention of the sealant.
