Group A: Colgate Cavity Protection; Group B: Sensodyne Total Care; Group C: Clinpro Tooth Crème (brushing only); Group D: Clinpro Tooth Crème (brushing and topical application). A positive value of percentage change indicates an improvement in sensitivity at the time of assessment compared to baseline.
CMS: combined modalities score is the average of all testing modalities, evaporative, tactile, and hypertonic.
Adjusted baseline means from ANCOVA: evaporative = 4.35; tactile = 2.00; hypertonic = 2.12; CMS = 2.83.
