Dental Health State Utilities and Oral Health Beliefs in Periodontitis

Condition(s) studied

Investigational drug(s) / intervention(s)

Health Utility State Assessment: Dental health utility state and oral health beliefs will be assessed through clinical examination and questionnaires.

Study summary

This observational, cross-sectional study addresses gaps in periodontal health economics by measuring dental health state utility values (HSUVs) for periodontitis treatment. While Oral Health Related Quality of Life outcomes dominate current research, Health State Utility values are rarely measured and seldom applied . The few existing utility studies are methodologically limited. The primary aim is to measure Health state utility values for periodontal health states using direct elicitation methods ( Standard Gamble) in patients with clinically diagnosed periodontitis. The secondary aim is to examine associations between patient-elicited utility values, clinical periodontal status (CAL, PD, BoP), and psychosocial beliefs from the Health Belief Model including perceived susceptibility, severity, benefits, and barriers. Participants will complete utility tasks and Health belief model questionnaires in a single visit. By integrating preference-based utility measurement with clinical and psychosocial constructs, this study will provide essential data for cost-utility modelling of periodontal interventions and support patient-centered care.

Eligibility

Primary outcome measure(s)

• Dental Health State Utility value — Baseline
  Health state utility values elicited using the Standard Gamble method using questionnaires having minimum value:0 and maximum value:1. Higher score indicates better perceived dental health state. A score of 1 represents perfect dental health and 0 represents a state equivalent to death
• Oral Health beliefs — baseline
  Oral Health beliefs using Health belief model questionnaire for periodontal disease. It is a 15 items questionnaire using a 5-point Likert scale from1 = strongly disagree to 5= strongly agree. Minimum score: 15 to maximum score: 75. Higher score indicate stronger positive oral health beliefs regarding periodontal disease susceptibility and severity
