Is Cavity Lining Really Necessary After Selective Caries Removal in Primary Teeth?

Abstract

Objective: To evaluate the clinical and radiographic response of pulp-dentin complex after selective caries removal with or without pulp lining in primary teeth. Material and Methods: Twenty-four primary molars with deep occlusal caries lesions and without pulpal alterations were selected from children, both genders, aged between 5 and 9 years old. After selective caries removal, the teeth were divided into three groups: without cavity liner (Group I), calcium hydroxide cement – CH (Group II), and Mineral trioxide aggregate – MTA (Group III). The final restoration was performed with resin-modified glass ionomer cement. Clinical and radiographic assessments were conducted at 6-month follow-up. The Kappa test determined intraexaminer reliability. Fisher's exact test evaluated intergroup comparisons (p0.05). Conclusion: Selective caries removal without cavity lining was acceptable for deep caries lesions in primary teeth.
