Purpose:
The objective of this study was to assess in vitro the tensile bond strength of a self-etching and 2 total-etch, single-bottle adhesive systems to primary dentin.
Methods:
Thirty-six sound primary canine buccal surfaces were randomly assigned to 3 groups (N = 12), corresponding to the tested adhesive systems: (1) group I = Excite (EX); (2) group II = Single Bond (SB); and (3) group III = Prompt L-Pop (PLP). After 24-hour storage in distilled water, tensile bond strength was tested for failure at a crosshead speed of 0.5 mm/min.
Results:
Means (MPa) and standard deviation (+/-) were: (1) EX = 12.72 (+/- .89); (2) SB = 10.86 (+/- 2.09); (3) PLP = 8.66 (+/- 2.23). Single Bond and Excite showed statistically similar results (P >.05) and provided the highest means. Prompt L-Pop was statistically different from the other groups (P < .05) and reached the lower bond strength to primary dentin.
Conclusions:
Total-etch agents provided the best overall bonding performance, whereas the all-in-one, self-etching, self-priming adhesive system yielded remarkably lower bond strength to primary teeth dentin.
