Plain English summary of protocol

Background and study aims
Many patients are hesitant to start orthodontic treatment before cosmetic dental work like veneers or crowns. This study aims to find out whether using technology to show patients what their smile could look like after treatment helps them feel more confident in choosing orthodontics before restorative procedures.

Who can participate?
Adults aged 18 to 60 years old who are unhappy with their smile and need both orthodontic and restorative treatment, and who have good oral and general health.

What does the study involve?
Participants will be randomly placed in one of two groups. One group will receive a standard consultation. The other group will use a computer simulation to preview how their smile will look after treatment. All participants will answer a short questionnaire about their decision, confidence, and satisfaction.

What are the possible benefits and risks of participating?
There are no known physical risks. The main benefit is that participants may better understand their treatment options and feel more confident in their decisions. Their participation will help improve how dentists use technology in consultations.

Where is the study run from?
Miracle Dental Clinic, Bakhtyari, Jamal Irfan Street, As Sulaimaniyah (Iraq)

When is the study starting and how long is it expected to run for?
July 2025 to December 2025

Ethics approval(s)

Approved 16/07/2025, Ethics Committee of The College of Dentistry, University of Sulaimani (Old Campus, Iskan, As Sulaimaniyeh, Sulaimaniyeh, 46001, Iraq; +964 (0)7731087000; dentistry.ethics@univsul.edu.iq), ref: COD-EC-25-0084

Health condition(s) or problem(s) studiedMalocclusion
InterventionThe researchers will randomly assign patients to either a group using digital reality technology for treatment planning or a control group without it, and will compare outcomes related to decision-making.

Method of randomisation:
Participants will be randomized using computer-generated simple random numbers in a 1:1 ratio.

Arm 1 (Control Group): Standard consultation with explanation and 2D images only.
Arm 2 (Intervention Group): Digital reality-assisted consultation using digital smile design and virtual simulation to preview the anticipated outcome.
Intervention typeBehavioural
Primary outcome measurePatient decision to accept or reject orthodontic treatment, measured using a single-item questionnaire with a binary (Yes/No) response immediately after consultation
Secondary outcome measures1. Patient satisfaction with the consultation process, measured using a 1–7 Likert scale questionnaire immediately after consultation
2. Patient understanding of treatment, measured using a 3-item Likert-scale questionnaire (1–7 scale) immediately after consultation
3. Confidence in treatment decision, measured using a 3-item Likert-scale questionnaire immediately after consultation
4. Willingness to undergo orthodontic treatment, measured with 3 questions on a 1–7 Likert scale immediately after consultation
Overall study start date16/07/2025
Completion date01/12/2025
