Nanofill composite resin has fine mechanical strength as hybrid composite and esthetic value as microfill composite. Attachment between composite resin and dental surface went through bond material. There were two methods of bond material application, total-etch and self-etch. The aim of this study was to compare tensile strength between self-etch adhesive and total-etch adhesive on class V cavity. This study used 32 samples of permanent premolar maxillary, caries-free, non abrasive buccal surface, haven't took dental restoration care. The teeth were registered on class V cavity preparation, its root were cut off to the lower cervix and planted on acrylic impression. Samples divided into 2 groups, first group were treated with nanofill composite resin with total-etch material, the second one with self-etch material. Samples were submerged into synthetic saliva for about 24 hours within 37˚C incubation. Samples were put on thermocycling under 60˚C and 4˚C temperature, 1 minute for each and repeated 25 times. Tensile strength of composite resin calculated using Universal Testing Machine. The data gained were analyzed by Independent t-test on 95% significance level. The study showed that between two treatment groups there were significant differences of tensile strength of p=0.000 (p<0.05) so it can be concluded that there were difference tensile strength of nanofil composite resin between total-etch adhesive system and self-etch adhesive system. Sefl-etch adhesive system produced tensile strength as good as total-etch
