Abstract

<abstract abstract-type="main" id="ipd12059-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="ipd12059-sec-0001" sec-type="section"> <title>Objective</title> <p>Aim of this <italic>in vitro</italic> study was to compare self‐etch adhesives regarding microtensile bond strength (μ‐TBS) to dentin of primary teeth.</p> </sec> <sec id="ipd12059-sec-0002" sec-type="section"> <title>Methods</title> <p>Fifty freshly extracted primary molars were ground to expose caries‐free dentin. Specimens were bonded with ten self‐etch adhesives (iBond self‐etch/Heraeus, Xeno V+/Dentsply, G‐Bond, Gaenial Bond/GC, BeautiBond/Shofu, AdheSE One F/Ivoclar Vivadent, Adper Easy Bond/3M ESPE, Clearfil SE Bond/Kuraray, OptiBond XTR/KerrHawe, Prime&Bond NT/Dentsply). After 24‐h storage (distilled water, 37°C), resin–dentin beams were cut and 848 resin–dentin sticks were subjected to μ‐TBS tests. Fracture analysis was carried out at 40× magnification under a fluorescence microscope and under a SEM.</p> </sec> <sec id="ipd12059-sec-0003" sec-type="section"> <title>Results</title> <p>Three adhesives (iBond SE, Clearfil SE Bond, Prime&Bond NT) did not suffer pre‐test failures (PTF). AdheSE One F revealed the largest portion of PTF (28%; <italic>P</italic> < 0.05). Clearfil SE Bond and OptiBond XTR exhibited more cohesive fractures than the other adhesives (77.3% <italic>vs</italic> 64.8%; <italic>P</italic> < 0.05). iBond SE, Gaenial Bond, Clearfil SE, and OptiBond XTR achieved μ‐TBS of >60 MPa, whereas Xeno V+ and AdheSE One F ranged only at ~20 MPa (<italic>P</italic> < 0.05).</p> </sec> <sec id="ipd12059-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Within the limits of this study, the self‐etch adhesives under investigation proved different extents of initial μ‐TBS to primary dentin with iBond SE, Gaenial Bond, Clearfil SE, and OptiBond XTR having been most successful.</p> </sec> </abstract>
