Intraoral repair of fractured porcelain could be advantageous to both patient and dentist. The aim of this study was to evaluate the effect of heat treatment of the silane coupling agent by Er:YAG and CO<jats:sub>2<\/jats:sub> lasers on the microshear bond strength of a repair composite to feldspathic porcelain.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>Sixty ceramic blocks were prepared and randomly divided into six groups (n = 10): (i) HF + silane (HS); (ii) silane + CO<jats:sub>2<\/jats:sub> laser (SC); (iii) CO<jats:sub>2<\/jats:sub> laser + silane (CS); (iv) silane + Er:YAG laser (SE); (v) Er:YAG laser + silane (ES); (vi) bur + HF + silane (BuHS). An adhesive resin was applied to the prepared ceramic surfaces and light\u2010cured. Two transparent plastic tubes were placed perpendicularly to each ceramic block. The composite resin was then placed on the treated ceramic surface and light\u2010cured for 40 seconds. The bonded blocks were stored in distilled water at 37\u00b0C for 24 hours and subjected to 3000 thermocycles. Microshear bond strength (\u03bcSBS) tests were performed using a wire and loop method. Data were analyzed using one\u2010way ANOVA and Duncan's multiple range tests (<jats:italic>p<\/jats:italic> \u2264 0.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The comparison of the mean \u03bcSBS values showed no significant differences between the ES and HS groups (<jats:italic>p<\/jats:italic> = 0.914). On the other hand, the specimens in these groups exhibited significantly higher bond strengths than those in the other groups (<jats:italic>p<\/jats:italic> &lt; 0.01). The mean \u03bcSBS of the BuHS group was statistically similar to that of CS and SE groups (<jats:italic>p<\/jats:italic> &gt; 0.05). The \u03bcSBS for the SC group was significantly lower than that of the other groups (<jats:italic>p<\/jats:italic> &lt; 0.01), with the exception of the CS group (<jats:italic>p<\/jats:italic> = 0.674).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Treatment with Er:YAG laser prior to silane application can be as effective as HF etching.
