Background: Clinicians often use calcium hydroxide liners during stepwise treatment of advanced caries. In this randomized clinical trial, the authors compared the short-term outcome of stepwise caries removal with and without use of a calcium hydroxide liner in conjunction with provisional resin-modified glass ionomer (RMGI) restorations.
Methods: The authors included in the trial 98 patients aged 15 to 30 years who had a deep carious lesion in a posterior tooth.
