Treatment and study plan

AI-Based Video Education on Denture Care

Behavioral

The intervention consists of an AI-based educational video module, approximately 8 minutes in duration, designed to improve denture care practices. It uses step-by-step, visually engaging demonstrations with AI-guided narration to enhance understanding, recall, and adherence.

Conventional Oral Health Instruction

Behavioral

Participants in the control group will receive conventional oral health education delivered verbally and chairside by the prosthodontic team. The standardized instruction includes information on denture hygiene techniques, appropriate storage of dentures overnight, mucosal care

Primary outcomes

  1. Change in Oral Health-Related Quality of Life (OHIP-14 Score)

    Time frame: Baseline, 1 month, 2 months, and 3 months

    The primary outcome is the mean change in OHIP-14 total score from baseline to follow-up assessments.

Secondary outcomes

  1. Change in Denture Care Knowledge Retention Score

    Time frame: Baseline, 1 month, 2 months, and 3 months

    Measured using a structured denture care knowledge quiz assessing correct cleaning frequency, storage methods, avoidance of harmful practices, recognition of poor fit, and oral hygiene procedures.

  2. Patient Satisfaction with Educational Method

    Time frame: Baseline, 1 month, 2 months, and 3 months

    Measured using a 5-point Likert scale questionnaire evaluating clarity, usefulness, acceptability, and confidence in applying denture care practices after receiving the assigned intervention (AI-based video or conventional oral instruction).

  3. Compliance with Denture Hygiene Practices

    Time frame: Baseline, 1 month, 2 months, and 3 months

    Assessed with a structured self-reported checklist of daily denture care practices, including cleaning frequency, storage behaviour, and oral mucosal care.
