Effect of surface treatment of ethylene vinyl acetate on the delamination of custom-fitted mouthguards.

Background/aim: Contamination of ethylene vinyl acetate (EVA) during mouthguard fabrication can cause delamination. The study evaluated the effects of different EVA surface treatments on the contact angle, laminate bond strength, and elongation capacity.

Materials And Methods: Specimens of two bonded EVA plates were prepared (n = 30).
