Overview

Brief Summary

This study aimed to compare experiences between adult patients receiving clear aligners and fixed appliances during the initial stage of orthodontic treatments.

Detailed Description

Patients receiving either clear aligner treatments were enrolled in this study. During the same time period, patients receiving fixed orthodontic treatments well-matched with clear-aligner patients by similar ages (difference \< 3 years), same gender and similar levels of severity of malocclusion \[similar Index of Complexity Outcome and Need (ICON) level\] were enrolled.The two groups were well-matched with ages, gender and levels of malocclusion severity. Pain perception, anxiety and quality of life were assessed through visual analogue scale (VAS), state-trait anxiety inventory (STAI) and oral health impact profile-14 (OHIP-14), respectively.

Outcomes

Primary Outcomes

The chronological changes in pain perception

Time Frame: Baseline, Day 1, Day 2,Day 3,Day 4,Day 5,Day 6,Day 7,and Day 14

The chronological changes in pain perception during the fortnight of orthodontic treatment were assessed through visual analogue scale (VAS). Participant is asked to place a line perpendicular to the VAS line.The score is determined by measuring the distance (mm) on the 10-cm line between the "no pain"anchor and the patients' mask,providing a range of scores from 0-100. A higher score indicates greater pain.

Secondary Outcomes

  • The chronological changes of anxiety level(Baseline, Day 1,Day 3,Day 5,Day 7 and Day 14)
  • The chronological changes in quality of life(Baseline,Day 1 ,Day 7 and Day 14)
