“…Furthermore, variances in the mode of fracture between universal self-etch and total-etch adhesives are in accordance with the study of Schnebel et al . [ 29 ], which revealed that failure occurs mostly at the bracket–adhesive interface for total-etch adhesives, leaving the enamel surface intact, but more chair time is needed to eliminate the residual adhesive. Self-etched universal adhesives resulted in more failures at the enamel–adhesive interface.…”

INTRODUCTION: The demand by dental practitioners for adhesives led to the innovation of newer self-etched universal adhesive systems. The objectives were to evaluate the shear bond strength (SBS) of metal brackets bonded with Optibond eXTRa Universal self-etch adhesive and Transbond XT primer and also to assess the adhesive remnant index (ARI). MATERIALS AND METHODS: A total of 100 extracted human premolar tooth samples were divided into 2 groups (n = 50) according to the adhesive system employed: Transbond XT (3M Unitek) and Optibond eXTRa Universal (KaVo Kerr). In group A, Transbond XT primer was applied, and in group B, Optibond eXTRa was applied, and metal brackets (American Orthodontics) were bonded with the Transbond XT adhesive, followed by photopolymerization with LEDition. The samples were preserved in artificial saliva for 30 days. SBS was tested using a universal testing machine (DAK Series7200, India). The ARI was assessed at 10× magnification under a stereomicroscope (Meiji Techno, Japan). The SBS scores were subjected to independent sample t-test and ARI scores to Pearson's Chi-square test. RESULTS: The mean SBS and standard deviation of Transbond XT is 12.11 ± 2.6 MPa and that of Optibond eXTRa Universal is 11.36 ± 2.8 MPa, revealing a statistically nonsignificant difference. Transbond XT displayed higher ARI scores and was statistically significant ( P = 0.001). CONCLUSION: The Optibond eXTRa Universal adhesive appears to be preferable for orthodontic bonding as it exhibited clinically acceptable SBS and performed better in terms of the ARI.

“…Despite some currently available adhesive systems can dissolve the smear layer, the most common technique used for orthodontic brackets to enamel is still the total etch adhesive using orthophosphoric acid [5,6]. This adhesive system generates a rough area on the surface and microporosities for micromechanical retention which allows the incorporation of small resin "tags" within the enamel surface, thereby creating microscopic mechanical interlocks between the enamel and resin [7,8].…”

Ultrashort pulsed laser conditioning of human enamel: in vitro study of the influence of geometrical processing parameters on shear bond strength of orthodontic brackets

The surfaces of 63 extracted premolar teeth were processed with intense ultrashort laser pulses (λ = 795 nm; pulse duration, 120 fs; repetition rate, 1 kHz) to produce cross patterns with different pitches (s) in the micrometer range in order to evaluate the influence of such microstructures on the shear bond strengths of orthodontic brackets to enamel. The samples were classified in nine groups corresponding to the control group (raw samples) and eight different laser-processed groups (cross patterns with s increasing from 15 to 180 μm). Brackets were luted with Transbond(TM) XT adhesive resin to all the samples; after 72 h, they all were submitted to strength test in a universal testing machine. Additionally, a third of the samples underwent morphological analysis of the debonded surface by means of scanning electron microscope microscopy and an analysis of the failure mode based on the adhesive remnant index. The results showed that enamel microstructuring with ultrashort laser pulses remarkably increase the bond strength of brackets. Dense cross patterns (s < 90 μm) produce the highest increase of bond strengths as compared to control group whereas light ones (s > 90 μm) give rise to smaller improvements of the bond strength. A strong correlation of this behavior with the predominant failure mode in both scenarios was found. So far, the best compromise between suitable adhesive efficiency, processing time minimization, and enamel surface preservation suggests the performance of cross patterns with pitches in the order of 90 μm.

“…Enamel fractures were frequently observed on tooth surfaces with brackets bonded through etch and rinse technique. Various factors can influence the bonding strength force of the brackets to the enamel such as the type of adhesive, the thickness of the adhesive layer, humidity, geometry of the bracket base,oral habits,etc, but the main one seems to be the etching technique [5][6][7][8][9].…”

“…Schnebel states that the adhesive force of the selfetching systems is not appropriate for bracket bonding and suggests that in order to gain enough bond strength orthodontists should use the classic etching technique [7]. The type of adhesive influences the bond strength, the risc of damaging the enamel and the presence of composite resin on the tooth surface [8].…”

ABSTRACT. Direct bonding of the bracket to the enamel is the elective procedure for the orthodontic treatment. Among various factors influencing the adhesive force at the enamel level, the etching technique seems to be the most important one. The present study aims at evaluating the influence of the storage media and the etching technique used, on the bond strength between different bracket types and dental structures. The results of this study showed that, regardless of the brackets and the immesion solution used, by working with the classic etch and rinse technique the adhesion force is higher than by using a self etching adhesive.
