A Systematic Review and Meta-Analysis of Baseline Ohip-Edent Scores

Area of Science:

• Dental Public Health
• Quality of Life Research
• Oral Health Assessment

Background:

• The Oral Health Impact Profile-Edentulous (OHIP-EDENT) is a key measure for assessing Oral-Health-Related Quality of Life (OHRQoL) in edentulous patients.
• Existing literature lacks established normal variance and mean values for baseline OHIP-EDENT scores.
• Knowledge of normal baseline scores is crucial for critically appraising studies and quantifying variations in initial OHRQoL.

Purpose of the Study:

• To systematically review and meta-analyze existing literature to quantify a normal baseline value for pre-operative OHIP-EDENT scores.
• To establish a reliable benchmark for the initial OHRQoL of edentulous individuals.

Main Methods:

• A systematic literature review was conducted to identify relevant studies.
• 83 papers containing OHIP-EDENT data were initially identified.
• After screening and eligibility assessment, 7 papers were included in the final meta-analysis.

Main Results:

• A random-effect model meta-analysis was performed on the 7 selected papers.
• The pooled mean baseline OHIP-EDENT score was determined to be 28.63.
• The 95% Confidence Interval for the mean baseline score ranged from 21.93 to 35.34.

Conclusions:

• A pre-operative baseline value for OHIP-EDENT scores has been successfully established through meta-analysis.
• This established baseline facilitates standardized comparison of initial OHRQoL across different study populations.
• The findings will aid in a more robust interpretation of OHRQoL in edentulous patients within published research.
