Glyceryl trinitrate Study. (a) Effect of glyceryl trinitrate (100, 150 or 200 μg) on pain intensity when infused into the surgical site of third molar tooth extraction over 20 min (n = 18-20 per group). (b) Effect of glyceryl trinitrate (150 or 200 μg) on pain intensity when infused into the surgical site of third molar tooth extraction over 20 min n = 20 & 37 for the placebo and glyceryl trinitrate groups respectively; p = 0.038; repeated measure 2 way ANOVA. (c) Dose response curve of glyceryl trinitrate's effect on pain intensity when infused into the surgical site of third molar extraction. Linear regression shows a slope significantly different from zero (n = 18-20 per group).
