 The intent of this study was to find out which of the two products yielded better results as a pulp capping agent. In order to detect this, the failure rates in the two treatment groups were compared using statistical tests. Distributions of covariates in the two treatment groups were compared and clinical judgment was used to identify covariates with serious group imbalances that would cause an unusual result for the primary analysis. Logistic regression was used to compare failure rates while adjusting for any covariates that were imbalanced between groups.
