Pulpotomy is a clinical procedure widely applied for treating exposed pulps due to caries. After pulpectomy treatment, the radicular pulp should be kept vital, uninfected, and enclosed in the dentin chamber using a dressing material [In the recent decades, MTA has been the gold standard material for pulp capping of primary molars after pulpotomy [Recently, a newer resin-based material has been introduced for endodontic treatments: TheraCal. This light-cured Portland cement-based resin consists of tricalcium silicate particles in a hydrophilic monomer that imitates the hydroxyapatite structure. Also, releasing calcium ions by TheraCal stimulates secondary dentin formation, as well as cell growth and proliferation [Overall, the findings on using TheraCal compared to other standard biomaterials including MTA have been promising, and it is a potential bioinductive agent that can be easily applied especially in pediatric patients. Accordingly, this study is aimed at evaluating and contrasting the success rates of TheraCal and MTA in terms of clinical and radiographic outcomes of pulpotomies in primary molars. This study was designed as a split-mouth randomized controlled clinical trial with two follow-up sessions after 6 and 12 months.
