What is the best method for debonding metallic brackets from the patient's perspective?

Area of Science:

• Orthodontics
• Dental Materials Science
• Clinical Dentistry

Background:

• Orthodontic metallic bracket removal can cause patient discomfort.
• Evaluating patient-reported pain during debonding is crucial for clinical practice.

Purpose of the Study:

• To compare patient-discomfort levels during metallic bracket removal using four distinct debonding instruments.
• To identify which instrument provides the least painful debonding experience.

Main Methods:

• A split-mouth study involving 70 patients (840 teeth) was conducted.
• Four debonding instruments were tested: lift-off debonding instrument (LODI), straight cutter plier (SC), how plier (HP), and bracket removal plier (BRP).
• Patient discomfort was assessed using a 0-10 visual analog scale (VAS) after debonding each quadrant.

Main Results:

• The straight cutter plier (SC) resulted in significantly higher pain scores compared to all other methods.
• The lift-off debonding instrument (LODI) group reported the lowest pain scores.
• No significant differences in pain scores were found between the how plier (HP) and bracket removal plier (BRP).

Conclusions:

• The lift-off debonding instrument (LODI) is associated with lower pain and discomfort during metallic bracket removal.
• Straight cutter pliers (SC) lead to the highest levels of pain and discomfort during the debonding procedure.
• Significant differences exist in patient-reported pain across different orthodontic bracket removal instruments.
