Objectives: The aim of this in vivo study was to compare the anti‐plaque effect of warm and cold chlorhexidine gluconate irrigation on matured human plaque. Methods: In a split‐mouth design, the antibacterial effect of 47 °C “warm” 0.2% chlorhexidine solution was compared with that of 18 °C “cold” rinse at the same concentration on newly‐formed supragingival plaque that had been left undisturbed for 72 h. Before and 1 h after a 1‐min rinse procedure, plaque was sampled from 10 test persons and vitality determined using vital fluorescence technique. Results: Cold and warm 0.2% chlorhexidine solution reduced plaque vitality significantly from 99.63% to 77.81% ( p =0.014) and from 98.98% to 51.77% ( p <0.001), respectively. Rinsing with warm chlorhexidine solution reduced plaque vitality to a significantly greater degree ( p =0.003) than did cold chlorhexidine. Conclusion: In this study, warm 0.2% chlorhexidine rinse showed a significantly more intensive anti‐plaque effect than cold chlorhexidine solution at the same concentration.
