Contributing co-variables in clinical trials.
To accurately compare Class V dentinal bonding studies, it is essential to critically classify the effects of the intraoral location and age of the patient on the retention of resin composite restorations. A mathematical formula for normalization combined with the Weibull analysis also is proposed that could provide CL50 values for the clinical longevity of adhesive restorations.
