Bottom Line: The results of the study showed there was no statistical significance in the shear bond strength according to an analysis of variance (P = 0.207) of the four groups.Chi-square comparison for the ARI indicated that there was a significant difference (P = 0.003) between the groups.The ARI score showed a self-etching adhesive the debonding occurred more within the adhesive interface leaving less composite adhesive on the tooth surface making it easy to clean up.

ABSTRACT

Background: The aim of the study was to determine and compare the shear bond strength of brackets bonded with Adper Promt self-etching adhesive (3M ESPE), Xeno III self-etching adhesive (DENSPLY), Transbond plus self-etching adhesive (3M) with that of conversional bonding procedure, and to calculate the adhesive remnant index (ARI).

Materials and methods: Totally, 60 maxillary premolar teeth were collected, and divided into Group I (Blue): Transbond™ XT primer, Group II (Purple): Adper™ Prompt™ self-etching adhesive, Group III (Orange): Xeno III® self-etching adhesive, Group IV (Pink): Tranbond™ Plus self-etching adhesive.

Results: The results of the study showed there was no statistical significance in the shear bond strength according to an analysis of variance (P = 0.207) of the four groups. The mean shear bond strength of Groups I, II, III, IV were 14.56 ± 2.97 Megapascals (MPa), 12.62 ± 2.48 MPa, 13.27 ± 3.16, and 12.64 ± 2.56, respectively. Chi-square comparison for the ARI indicated that there was a significant difference (P = 0.003) between the groups.

Conclusion: All the four self-etching adhesives showed clinically acceptable mean shear bond strength. The ARI score showed a self-etching adhesive the debonding occurred more within the adhesive interface leaving less composite adhesive on the tooth surface making it easy to clean up.

Mentions: Totally, 60 teeth were collected, thoroughly cleaned and stored in formalin at room temperature and they were randomly assigned to four sub samples with 15 teeth per sub-sample and were color coded (Blue, Purple, and Orange, Pink). Acrylic stubs were used to mount the teeth, and they were oriented in a way to ensure that the buccal contours of the teeth are perpendicular to the bracket base (Figures 1 and 2).
