Methods A total of 192 children with deep caries in the two symmetric primary molars were studied. The two symmetric primary molars were divided into two groups for treatment with chemomechanical method with CarisolvTM system or traditional mechanical method. After caries removal, calcium hydroxide agent was placed as the protective base, and glass ionomer cement was used to restore the teeth. The patients were followed up every 1 month within one year after the operation. Results The percentage of healthy primary molar pulp was 95.3% with chemomechanical method and 87.0% with traditional method, showing a significant difference between the two methods. Conclusion Chemomechanical caries removal is more effect
