Abstract
This study was not able to substantiate the manufacturers' claims that self-etching primers (SEPS) can be used on wet enamel.

Combining etching and priming by the use of a SEP reduces the steps and time required to bond orthodontic brackets to enamel. Notwithstanding that a SEP would inevitably minimise the potential for salivary contamination, the aim of this study was to examine if salivary contamination is detrimental to bond strengths. Using a universal testing machine, shear bond testing was carried out after bonding stainless steel brackets to 135 bovine incisor crowns. Of the three systems tested, Transbondâ„¢ Plus Self Etching Primer (3M Unitek) had the highest shear bond strengths. Generally, these values reduced after contamination with the artificial saliva, although rinsing with water after contamination restored original bond strengths. It should be noted that the artificial saliva used in this study was carmellose sodium.
