Title Bonding of Scotchbond Multi-Purpose Vs Self-Etching Systems In Restoring Class V Lesions
Clinical Question In a healthy adult patient with non carious class V lesions does Scotchbond multi-purpose provide a more reliable bond than self-etching adhesive when restoring with composite resin?
Clinical Bottom Line Scotchbond multi-purpose provides a better bond in class V composite resin restorations than self-etching bonding systems.

#1) 16430011Owens/2005Extracted teethIn Vitro Study
Key resultsAt the coronal and apical restoration margins, Scotchbond multi-purpose exhibited significantly less leakage than the self-etching adhesive. Results were analyzed and yielded a p < 0.05 level of significance.
#2) 16536195 Owens/2006Extracted teethIn Vitro Study
Key resultsScotchbond multi-purpose exhibited significantly less leakage than the self-etch adhesive groups (p=0.0138). Results were analyzed and yielded a p < 0.05 level of significance.

Comments on
The Evidence
Randomized studies were performed on extracted teeth. Teeth were selected based on being molars and non-carious, then randomly assigned into groups. All results were subject to statistical analysis and demonstrated sample size adequate for the given results.
Applicability These in vitro studies may approximate the conditions of actual, patients, but in vivo conditions may differ. The treatments used are practical and feasible in a dental office. No potential harm is seen applying the results to clinical scenarios in which the benefit of reliably bonded restorations may be obtained.

This CAT was further researched for update in current literature November 2017. A 2 year RCT by Lawson et al. 2015 (PMID #26231300) was identified which compared Scotchbond Universal self- etch and total etch to the Scotchbond Multipurpose in class V lesions at baseline, 6, 12 and 18 months. This study concluded there was no significant differences between adhesive materials when analyzing performance for all outcomes. These findings conflict with the original bottom line that Scotchbond multi-purpose provides a better bond for class V resin restorations. Further study is recommended with larger participants, randomized intervention. However, currently this RCT is the highest level evidence and it’s results should be considered by practitioners when considering products for clinical preparations.
