Individual Z-score based quantitative sensory testing (QST) profiles from the attached gingiva after application of capsaicin (A), menthol (B) or saline (C) (n = 15). Part D shows the averaged Z scores. CDT, cold detection threshold (°C); WDT, warmth detection threshold (°C); TSL, thermal sensory limen (°C); CPT, cold pain threshold (°C); HPT, heat pain threshold (°C); PPT, pressure pain threshold (kPa); MPT, mechanical pain threshold (mN); MPS, mechanical pain sensitivity (mean pain rating, 0–100); WUR, wind-up ratio; MDT, mechanical detection threshold (mN); VDT, vibration detection threshold (/8); PHS, paradoxical heat sensation (/3); ALL, dynamic mechanical allodynia. NRS, numerical rating scale (pain intensity from 0–100). The grey zone (Z score between −1.96 and 1.96) represents the 95 % confidence interval of baseline values.
