Quality and intensity of pain associated with continuously applied orthodontic stresses of relatively high and low magnitudes
Abstract
The purpose was to assess longitudinally pain intensity and quality during tooth
translation by 2 continuous stresses. Eight subjects (five males, 3 females) who required
maxillary first premolar extractions had maxillary canines retracted segmentally using 4 kPa
on one side and 78 kPa on the other. Subjects scored Modified McGill Pain Questionnaire-
Short Forms (MMPQ-SF), Visual Analogue Scales (VAS), and Present Pain Intensities (PPI)
for both sides at the beginning of 13 appointments during 4 phases: baseline, post-placement
of separators, early and later tooth-loading. Pain intensity (MMPQ-SF, VAS, PPI) and generalized/emotional subscale scores
showed no significant differences between stresses. Localized subscale scores were higher
for 78 kPa compared to 4 kPa sides. Females tended to report higher VAS and PPI compared
to males. Significant differences were found between baseline and post-placement of
separators and between baseline and early tooth-loading using MMPQ-SF and localized
subscale scores.
