Özet
Maintaining pulp vitality is one of the most important issues in
dentistry and the quality of the bond strength of calcium silicatebased cements (CSCs) used for this purpose to restorative material directly affects the long-term success of the treatment. This in
vitro study aimed to evaluate microshear bond strength (mSBS) of
several CSCs to composite resin using a universal adhesive in
both etch-and-rinse and self-etch modes and to examine surface
characteristics after acid etching. Five CSCs, namely Angelus MTA,
Biodentine, NeoMTA, TheraCal LC, and Well Root ST were evaluated. Fifteen specimens per group were used for determining
the mSBS to composite resin. The composite resin was applied
over CSCs using a universal adhesive either in etch-and-rinse or
self-etch modes, and mSBS of CSCs to composite resin was
assessed. The effect of acid etching on the surface morphology
and Ca/Si ratio of CSCs were examined by SEM-EDX microanalysis.
The highest mSBS was obtained for TheraCal LC in both etch-andrinse and self-etch modes. No significant difference was
found between Biodentine and MTA-based cements in the etchand-rinse mode, whereas in the self-etch mode, Biodentine displayed a significantly superior bond strength. The results of SEM
demonstrated distinct morphological alterations after acid etching. Acid etching decreased the Ca/Si ratio of the substrate surface by approximately 4-fold for all CSCs. TheraCal LC is more
suitable for vital pulp therapy with its superior bond strength to
composite resin. Furthermore, it may be suggested that adequate
adhesive performance may also be achieved without an
acid etching.
