Evaluation of Long-term colour resistance of composite materials used in aligner treatments: A comparative study.

Aim: The aim of this study is to evaluate the discolouration resistance of attachments made of composites having different physical properties, filler ratios and viscosity through the simulated environment and conditions.

Materials And Methods: Seventy-two extracted human teeth were aligned to simulate upper and lower dental arches. The attachments were prepared according to the guides determined by ClearCorrect.

Comparison of Pain Levels on Patients Undergoing Fixed Orthodontic Treatment with 2 Different Self-Ligating Bracket Systems.

Objective: Comparison of pain levels of patients treated with 2 different passive self-ligating bracket systems right after initial archwire placement.

Methods: A total of 34 patients with mild crowding were allocated randomly to 2 groups to be treated using 2 different self-ligating brackets. 0.
