Brief 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.

Outcome Measures

Primary Outcomes (2)

• Dental Health State Utility value

  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

  Baseline

• Oral Health beliefs

  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

Study Arms (1)

Periodontitis Patients

Patients aged 30-50 years with a clinical diagnosis of periodontitis according to the 2017 World Workshop Classification. Complete periodontal examination will be done comprising of recording pocket probing depth (PPD), clinical attachment level (CAL) at six sites per tooth, bleeding on probing (BoP), plaque index (PI) and gingival index(GI).

Other: Health Utility State Assessment

Interventions

Health Utility State Assessment OTHER

Dental health utility state and oral health beliefs will be assessed through clinical examination and questionnaires.

Periodontitis Patients

Eligibility Criteria

• Age: 30 Years - 50 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64)
• Sampling Method: Non-Probability Sample

Study Population

Patients aged 30- 50 years attending the outpatient Department of Periodontology with a confirmed clinical diagnosis of periodontitis based on the 2017 World Workshop Classification. Participants were recruited consecutively from routine clinical appointments. All participants had at least 20 natural teeth, no history of periodontal surgery in the past 6 months, and were able to complete utility elicitation tasks and self-administered questionnaires . Patients with history of antibiotic use within last 3 months, steroid, immunosuppressive and psychiatric drug use or pregnancy were excluded.

You may qualify if:

• Adult patients with age group 30-50 years diagnosed with generalized periodontitis.
• Presence of minimum 20 teeth excluding third molars
• Able to read/understand Hindi or English (for questionnaires)

You may not qualify if:

• Systemic diseases that may affect periodontal disease progression or outcome of treatment (diabetes, autoimmune diseases)
• History of Periodontal treatment within last 6 months
• History of Antibiotic use within the previous 3 months
• History of Steroid, immunosuppressive and psychiatric drug use
• Pregnant and lactating women
• History of Smoking or substance abuse
