Outcomes of one-step incomplete and complete excavation in primary teeth: a 24-month randomized controlled trial.

Aim: To compare 24-month pulp health outcomes of partial caries removal (PCR) and total caries removal (TCR) with composite restoration in primary molars.

Methods: 48 children aged 3-8 years with at least one molar with a deep carious lesion were included. 120 teeth were randomized to control (TCR; n = 54; 69% class II) and test (PCR; n = 66; 63% class II) groups.
