About this study
Official title: Evaluation of Patient-centered Outcomes Associated With Acceleration of Lower Incisors Decrowding Using Self-ligating Brackets With and Without Piezocision in Comparison With Traditional Brackets: A Randomized Controlled Clinical Trial
The different types of brackets (e.g., self-ligating and conventional brackets), and the various acceleration methods (e.g., corticotomy) cause varying degrees of pain and discomfort. This study will assess pain, discomfort, and other patient-centered outcomes in adults with severe crowding on the upper jaw requiring two first premolars extraction.
There are three groups:
Read more
The first group (control group): the patients in this group will be treated using conventional brackets alone.
The second group (Experimental group): the patients in this group will be treated using self-ligating brackets alone.
The third group (Experimental group): the patients in this group will be treated using self-ligating brackets associated with flapless corticotomy.
Read the detailed description
Pain associated with orthodontic treatment is one of the undesirable complications, which negatively affects the patient's cooperation. Pain may occur due to the pressure on the periodontal ligaments induced by orthodontic forces. The perception of pain is affected by many factors related to the patient, such as age, gender and any previous treatment experiences, which are negatively or positively reflected on the patient's cooperation. As for the factors related to the type of orthodontic treatment provided, the pain and discomfort are proportional to the brackets system used and the forces applied, especially in the leveling and alignment stage. The amount of tooth movement is directly affected by the friction between the brackets and the wires used. The physical properties of the wire and brackets used and the dimensions of the applied wires, in addition to the type of ligation play a significant role in the amount of friction generated.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in the levels of pain
Patients will be asked this question about their feeling of pain (Item no 01):
'What is the degree of pain you have experienced?' A standardized questionnaire will be used to assess pain, discomfort and functional impairments' levels during the active phase of treatment. The patient will be asked to specify a point on the visual analogue scale (VAS), a 100-mm horizontal line with two focal points at its beginning and end (0: there is no pain - 100: the worst pain). The score will be determined by measuring the distance from the beginning until the point identified by the patient.
Measured: After 24 hours; 4 days; 7 days; 14 days; 28 days
Change in the levels of discomfort
Patients will be asked this question about their feeling of discomfort (Item no 02):
'What is the degree of discomfort you have experienced?' A standardized questionnaire will be used to assess pain, discomfort and functional impairments' levels during the active phase of treatment. The patient will be asked to specify a point on the visual analogue scale (VAS), a 100-mm horizontal line with two focal points at its beginning and end (0: there is no pain - 100: the worst pain). The score will be determined by measuring the distance from the beginning until the point identified by the patient.
Measured: After 24 hours; 4 days; 7 days; 14 days; 28 days
Change in the Perception of swelling
Patients will be asked this question about their feeling of swelling (Item no 03):

The score will be determined by measuring the distance from the beginning until the point identified by the patient.
Measured: After 24 hours; 4 days; 7 days; 14 days; 28 days
Change in the difficulty of mastication
'What is the degree of mastication difficulties you have experienced?' A standardized questionnaire will be used to assess pain, discomfort and functional impairments' levels during the active phase of treatment. The patient will be asked to specify a point on the visual analogue scale (VAS), a 100-mm horizontal line with two focal points at its beginning and end (0: there is no pain - 100: the worst pain).

The patient will be asked to specify a point on the visual analogue scale (VAS), a 100-mm horizontal line with two focal points at its beginning and end (0: there is no pain - 100: the worst pain). The score will be determined by measuring the distance from the beginning until the point identified by the patient.
Measured: After 24 hours; 4 days; 7 days; 14 days; 28 days
The levels of satisfaction
Patients will be asked this question about their levels of satisfaction (Item no 07): 'What is your levels of satisfaction on the orthodontic treatment provided?' A standardized questionnaire will be used to assess pain, discomfort and functional impairments' levels during the active phase of treatment. The patient will be asked to specify a point on the visual analogue scale (VAS), a 100-mm horizontal line with two focal points at its beginning and end (0: there is no satisfaction- 100: the highest satisfaction).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The different types of brackets (e.g., self-ligating and conventional brackets), and the various acceleration methods (e.g., corticotomy) cause varying degrees of pain and discomfort. This study will assess pain, discomfort, and other patient-centered outcomes in adults with severe crowding on the upper jaw requiring two first premolars extraction.
There are three groups:
The first group (control group): the patients in this group will be treated using conventional brackets alone.
The second group (Experimental group): the patients in this group will be treated using self-ligating brackets alone.
The third group (Experimental group): the patients in this group will be treated using self-ligating brackets associated with flapless corticotomy.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
