Brief 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.

Outcome Measures
Primary Outcomes (1)
Primary outcome (Alignment efficiency)
The study models, which should be free from any inconsistency (such as bubbles), were used to measure the Little's irregularity index (Little, 1975). This was calculated using a digital Vernier caliper to measure the extent of mesial and distal contact displacement from the mesial contact point of lower canine to that on the other side (to the nearest 0.01mm).

Eligibility Criteria
You may qualify if:
- Patients indicated for fixed appliance orthodontic treatment who have a moderate crowding (3-6mm) according to the Little's irregularity index (LII).
- Full set of lower permanent dentition excluding the third molars.
- No history of trauma or root resorption in the lower incisors.
You may not qualify if:
- Previous orthodontic treatment.
- Less than 3mm of lower incisor crowding (LII) or with spaced incisors.
- Severe crowding in the lower arch (greater than 7mm) which requires extraction.
- Blocked-out teeth that cannot be engaged with the aligning archwire.
- Patients with periodontally compromised teeth.

- Masking Details
- Blinding to treatment allocation was possible only for the investigator and data analyst because the clinicians could know the type of archwiers from their flexibility. All the trial documents were labeled with the study ID number, which was used for participant identification and data collection without unmasking the allocation group. This allowed the investigator to complete data collection and measurements blindly.
