Patients attending Dubai Dental Hospital and requiring nonsurgical periodontal therapy will be invited to take part in the study. Potential participants will be screened and selected based on the inclusion and exclusion criteria

The aims of the randomized controlled trial are:

1. To compare the influence of AI-generated instructions versus traditional methods in improving the oral hygiene habits of patients diagnosed with periodontitis
2. To assess the time and cost effectiveness of applying AI-generated oral hygiene instructions in daily practice
3. To evaluate the level of patients' engagement, preference, and satisfaction with technology-based interactions vs. patient-doctor interaction

Research design

• Prospective, in which participants will be recruited and then followed up throughout a specified period of time.
• Randomized, parallel designed, concurrent controlled trial with participants randomly allocated to either control or test groups.

The study will involve two stages, 1) Digital Avatar creation and 2) Clinical component.

The participants will be randomly allocated to two equal sized groups (30 per group) using computer-generated numbers:

Control group (C): Standard oral hygiene instructions will be given verbally by the periodontics resident.

Test group (T): Avatar-based group will receive oral hygiene instructions from a digital avatar of their choice.
