Abstract
Background: The development of 4th generation calcium silicate base materials with added resin, commercially known as Theracal LC®, aims to make pulp capping procedures easier.
Objective: To compare the clinical and radiographic success rates of pulp capping using Theracal LC® versus calcium hydroxide, with a follow-up period of no less than 6 months.
Methods: A systematic search was conducted using PubMed database, along with searches in open access databases and Google Scholar, supplemented by manual searching. Only English or Thai articles published between 2004 and 2024 were included. Nine articles were accepted and used for meta-analysis. The collected data included mean values and standard deviations of success rates for clinical and radiographic outcomes after pulp capping, with patient follow-up periods of 6 months or longer. Relative risk (RR) with 95% confidence intervals were calculated.
Results: A total of 9 articles were analyzed. Theracal LC® showed a higher number of teeth with successful clinical outcomes in pulp capping compared to calcium hydroxide, but the difference was not statistically significant (RR = 1.02, 95% CI 0.99-1.04, p=0.87). The data showed high homogeneity (I²=0.0%), though the number of studies was insufficient.
Conclusion: Theracal LC® demonstrated a higher number of teeth with successful clinical outcomes in pulp capping compared to calcium hydroxide, but the difference was not statistically significant.
