Pulp exposure rate · Patients with deep carious lesions in permanent (mainly posterior) teeth
Minimally invasive caries removal was associated with a lower mean pulp exposure rate than conventional removal (1.2% vs 8.1%), but the difference was not statistically significant (Wilcoxon, p = 0.068); certainty of evidence was not graded.
