Abstract

Abstract: Objective: To investigate the perception and effect of Er: YAG laser in the treatment of deep caries of primary teeth. Methods: Children aged 3-6 years were divided into Er:YAG laser group and traditional group randomly, then removed the decay and filled. The pain feeling of children, satisfaction of parents, and clinical effect were evaluated. Results: The average age of 108 children was 5.16 ± 0.81 years old and 224 teeth were treated. The pain level and parents' satisfaction in Er:YAG laser group was significantly better than traditional group (P<0.05). The time of caries removing was not statistically significant compared with the traditional group. In terms of clinical efficacy, within 6 months, the success rate in the Er:YAG laser group was slightly higher than traditional group. With the extension of observation time, the success rate of both groups decreased. After 2 years, the success rate was significantly higher than that of traditional group (P<0.05). The main reason of failure was secondary caries (35.05%), followed by loss of fillings (29.90%). Conclusion: Er: YAG laser is effective in the treatment of deep caries of primary teeth, which can effectively reduce the pain of children and is worthy of clinical application.
