Dear Editor,

We appreciate the opinions about our article [1] by Wiwanitkit. [2] The adhesives, mainly ethyl-cyanoacrylate, have been studied by our group in different features. [3],[4] Previously, we mentioned that "high temperatures related to exothermic reaction of ethyl-cyanoacrylate polymerization may possibly induce a temporary bactericidal effect" [ 3] like Dr Viroj Wiwanitkit cited very well in his letter to the editor. Other studies, however, suggest that the antimicrobial activity could be related to the degradation products. [5],[6] Formaldehyde, one of degradation products of cyanoacrylate, for example, destroys cell membranes by denaturing the membrane proteins. [7] Toxic degradation products of cyanoacrylate may further slow cell growth, damage its physiological needs, and change its cellular membrane structure by inhibiting a specific receptor. [8]
