Table 1a.

Mean and standard deviation of the intraoral quantitative sensory testing (QST) parameters from the attached gingiva buccal to the first premolar before and after z-transformation in the age- and sex-matched reference group and from the painful intraoral site in patients with atypical odontalgia (AO). The table also shows the frequency of patients and reference group participants presenting with z-score values outside the reference 95% confidence interval (−1.96 < z-score < 1.96)

Abs: absolute values of QST findings in the healthy reference group. CDT: cold detection threshold (Δ°C), WDT: warmth detection threshold (Δ°C), TSL: thermal sensory limen (°C), CPT: cold pain threshold (°C), HPT: heat pain threshold (°C), MDT: mechanical detection threshold (mN), MPT: mechanical pain threshold (mN), MPS: mechanical pain sensitivity, WUR: wind-up ratio, VDT: vibration detection threshold (/8), PPT: pressure pain threshold (kPa).

^az-transformed values outside the 95% confidence intervals of the normal range (a.m. [14]).
