Abstract:
Objective To investigate the initial temperature sensation and pressure pain sensation in patients receiving invisible or-thodontic treatment.Methods Twenty-two patients receiving clear aligner treatment(experimental group)and 22 volunteers(control group)participated.Perceptual changes were assessed using the visual analogue scale(VAS)and quantitative sensory testing(QST).The QST employed in this study included warm detection threshold/heat pain threshold(WDT/HPT),cold detection threshold/cold pain threshold(CDT/CPT),and pressure pain threshold(PPT).Tests were conducted on teeth 21 and 31,their gums,the left hand,and the left masseter muscle.Assessments occurred at baseline,2 hours,24 hours,7 days,and 28 days after aligner placement.Re-sults In the experimental group,VAS scores peaked at 24 hours and then significantly decreased(P＜0.01).For teeth 21 and 31,the WDT and HPT of the labial attached gingiva,along with the PPT of these teeth,showed significant decreases at 24 hours and 7 days compared to baseline and the control group(P＜0.01).At 24 hours and 7 days,VAS scores were negatively correlated with the WDT and HPT of the labial attached gingiva of teeth 21 and 31(P＜0.05).Conclusion At 24 hours and 7 days post-clear aligner treatment,thermal sensitivity and pain,as well as pressure pain sensitivity,increased for the gingiva of teeth 21 and 31.Thermal sensitivity was also correlated with pain intensity.
