About this study

Official title: Evaluation of the Effectiveness of the Weingart Plier in Combination With the Biting on Cotton Rolls in the Management of Pain During the Removal of Metal Brackets: A Randomized Controlled Trial

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:

Read more

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.

Read the detailed description

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.

Bracket removal using a Weingart plier with the mouth open, Biting on a cotton roll during brakcet removal

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Bracket removal using a Weingart plier with the mouth openProcedure or surgery

    The brackets will be removed using a Weingart plier. The patient will be asked to keep his mouth open during this procedure.

  • Biting on a cotton roll during brakcet removalProcedure or surgery

    The brackets will be removed using a Weingart plier. During this procedure, the patient will be asked to bite on a cotton roll.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Perceived Pain Intensity

    Pain intensity will be evaluated using a 100-mm Visual Analog Scale (VAS), where a score of 0 indicates "no pain" and 100 indicated "extreme pain".

    Patients will be asked to record the perceived pain immediately after removing each bracket.

    This evaluation will cover all teeth on the upper and lower jaws.

    Measured: This assessment will be done once at the time of removing brackets (i.e., the patient will record the level of perceived pain within few seconds after removing each bracket for each tooth)
