Indirect pulp capping (IPC) is a treatment that preserves pulp's vitality. Several materials have been used for this procedure. The aim of this study is to evaluate the radiographic and clinical outcomes of TheraCal LC (Bisco Inc., Schaumburg, IL, USA) and to compare it with mineral trioxide aggregate (MTA) (Pro Root MTA, Dentsply Tulsa, Johnson City, TN, USA) and calcium hydroxide \[Ca(OH)2\] (Dycal, Dentsply De Trey Konstanz, Germany) biomaterials in IPC treatment.
A total of 295 teeth, including second primary molars and first permanent molars with IPC indications from healthy and cooperative children between the ages of 4-15, were included in this study. Teeth were divided into three groups according to the materials used for pulp capping. Indirect pulp treatment was applied using Dycal for 91 teeth, ProRoot MTA for 89 teeth and TheraCal LC for 115 teeth. Primary molars were restored with the compomer material, and permanent molars were restored with the resin composite material. Restorations were evaluated with the Modified United States Public Health Service (modified USPHS) criteria. Clinical and radiographic findings were evaluated for 24 months at follow-up.

After cleaning the caries with partial removal (non-exposed pulp), cavity disinfected with sodium hypochlorite then indirect pulp capping agent was applied to cavity and restoration was finished in the same session.
