Summary

The aim of this study is to compare the effectiveness of using heat-activated NiTi with superelastic NiTi archwires during the initial phase of orthodontic treatment. Primary Objective: To compare the difference in the amount of crowding in the lower incisors after 4 and 8 weeks from the start of treatment. Secondary Objectives: 1. To compare the amount of orthodontically-induced inflammatory root resorption (OIIRR) in the apical region of mandibular central incisors between the two groups of archwires 2. To compare the amount of pain perception between the two groups of archwires during the 1st week after each wire placement.

Detailed description

Objectives: To compare the heat-activated nickel titanium (HANT) with superelastic nickel titanium (SENT) archwires in terms of their effectiveness in aligning teeth, possibility of inducing root resorption, and patient perception of pain during the initial phase of treatment. Subjects and Methods: Orthodontic patient aged 12 years or over with lower anterior crowding of 3-6 mm. who need treatment without extraction, were randomly allocated to the HANT and SENT archwires groups with a 1:1 allocation ratio. Archwire sequence in both groups was 0.014-inch and 0.016-inch, respectively. Each archwire was placed for 4 weeks. Outcome measures included the amount of crowding using Little's irregularity index (LII), apical root resorption, and pain perception. The effectiveness of alignment was tested using 2X2 mixed factorial ANOVA, while root resorption and pain perception were tested by the Mann-Whitney U test, and Wilcoxon signed-rank test (P\<0.05).
