COMPARISON OF SELF-ETCH AND CONVENTIONAL ACID-ETCH TECHNIQUES IN ORTHODONTIC BONDING PROCESS

In recent years, new adhesive methods have been replaced with conventional bonding methods which are used for bonding orthodontic attachments, protecting teeth and saving time. therefore; with the developing of the bonding procedures, new selfetching primers have been introduced. the advantages of the self-etching primers are; shorten application time due to not including acid-etching and washing processes, reducing salivary contamination because of easy application and fewer moisture sensibility. in the literature, conventional acid-etching and self-etching techniques are compared with regard to shear bond strength, adhesive remnant index scores, mean bonding time and survival period on teeth. apart from these, studies about the effects of salivary contamination on the bond strength exist.
