Patients at the Orthodontic Department of the University of Damascus Dental School will be examined, and subjects who meet the inclusion criteria will be included. Then after finishing the orthodontic treatment, Patients were randomly assigned into two groups:

Open mouth group:

The debonding procedure was conducted using the open-mouth technique. All brackets were removed using a Weingart plier (American Orthodontics, Sheboygan, Wisc) by squeezing them from both sides of the mesial-distal surfaces. Before debonding, the stainless steel finishing archwires (0.017 × 0.025 inches) were removed.

Biting-on a-cotton-roll-group:

All brackets were removed using the same plier. The brackets were debonded using a Weingart plier (American Orthodontics, Sheboygan, Wisc) by squeezing them from both sides of the mesial-distal surfaces. Additionally, cotton rolls were placed between the upper and lower teeth, and patients were instructed to bite on them during the procedure. Before debonding, the stainless steel finishing archwires (0.017 × 0.025 inches) were removed. Patients in the second group were instructed to bite on a cotton roll throughout the debonding process.

Pain is a subjective experience that can vary widely among individuals. It is influenced by several factors, including age, gender, personal pain threshold, psychological and social conditions, past negative experiences, and the degree of force applied.

Although various methods for bracket debonding, such as ultrasonic instrumentation, lasers, and electro-thermal debonding, are documented in the literature, hand tools like Weingart pliers remain among the most practical solutions. This study focused on using Weingart pliers to compare the pain scores in two techniques-open mouth and biting on a cotton roll-during bracket removal. These methods are widely used in orthodontic clinics and are readily available to orthodontists.

Inclusion Criteria:

• Patients aged 16 to 25 years,
