Advantages of Self-etch versus Etch-and-rinse systems [October 21, 2017]

Search result: 10 articles reporting on 5 clinical trials after different follow-up periods were found.

Clinical outcomes: The results indicate no difference in retention and anatomic form of restorations after 1 – 3 years. Marginal adaptation appears to be superior for etch-and-rinse systems after 1 – 2 years and no difference was found after 3 years. Marginal discoloration is significantly more observed for (1-step) self-etch systems. Post-operative sensitivity was the same for both systems in all trials. Contradicting evidence was found for clinical success rate of self-etching adhesive (G-Bond) adhesives after 5 years and a higher failure rate for self-etch systems after 6 years.

[‘Preliminary Systematic Literature Searches’ are based on SYSTEM’s periodic systematic searches of the dental literature and provide first overviews over existing clinical evidence but are limited in the number of databases searched, as well as the assessment of precision and internal validity of results and thus do not replace the need for a full systematic review report to the topic]
