Subjective ability to discriminate differences in intensity of forces applied to maxillary canines, and to mandibular incisors, canines, and first premolars was evaluated. Least relative differences in force could be discriminated through the maxillary canines (8.6 to 9.5%). Individuals showed nearly the same discriminatory ability for all mandibular teeth tested.
