Oral Health Impact Profile-14 (OHIP-14)
Oral Health Impact Profile-14 · Also known as: OHIP, Oral Health Impact Profile
The OHIP-14 is a 14-item, validated instrument measuring the impact of oral conditions on quality of life and functional well-being. Developed by Slade in 1997, it is a shortened form of the original 49-item OHIP and has become the gold standard for assessing oral health-related quality of life in clinical research and practice. It captures patient-centred outcomes across functional, psychological, and social dimensions.

When to use it
The OHIP-14 is used in epidemiological surveys, clinical trials evaluating dental treatments (orthodontics, implants, periodontal therapy, denture renewal), health services research, and clinical practice to track patient-centred outcomes. It is appropriate for adults (18+) across all socioeconomic and education levels and has been validated in diverse populations. It is particularly valuable when assessing interventions where quality-of-life benefit is a key outcome (e.g., does new denture or orthodontic treatment improve function and well-being beyond clinical measures?).
Strengths & limitations
- Psychometrically sound with high internal consistency (Cronbach α = 0.88-0.90) and test-retest reliability (ICC = 0.80-0.89) across populations
- Shortened form (14 vs. 49 items) balances comprehensive measurement with practicality; responsive to clinical change in trials
- Widely translated (40+ languages) with cross-cultural validation, facilitating international comparisons
- Captures both objective functional impacts and subjective psychological/social burden, aligned with biopsychosocial model
- Free, open-access instrument; no licensing fees or permission barriers for researchers and clinicians
- Self-report bias: relies on patient memory and perception; may not correlate perfectly with clinical measures of disease severity
- Ordinal scale treated as continuous; some analyses may violate assumptions; non-parametric alternatives recommended
- Recall period (past month) may not suit acute post-operative settings; modified versions with shorter windows have been used
- Subscales (2 items each) are brief; some studies report low discrimination at subscale level; total scale is more reliable
Frequently asked
Is OHIP-14 suitable for children and adolescents?
The original validation was in adults; a child-specific version (Child-OIDP, COHIP) is available for ages 6-11. For adolescents 12-17, OHIP-14 has been used with acceptable psychometrics, but child-adapted instruments are preferable to ensure developmental appropriateness of language.
How do I interpret a change of 5 points between baseline and follow-up?
The minimal clinically important difference (MCID) for OHIP-14 is approximately 4-6 points, depending on population and context. A 5-point improvement represents a clinically meaningful benefit; a 5-point worsening suggests functional deterioration warranting clinical review.
Can I use OHIP-14 in edentulous (no teeth) patients?
Yes, OHIP-14 includes denture-related items and has been validated in edentulous cohorts. Items refer to 'teeth, mouth or dentures', accommodating patients with complete dentures.
Is there a license or permission required to use OHIP-14?
OHIP-14 is in the public domain; no license fee or formal permission is required. Citation of Slade (1997) is standard practice. Some countries' copyright offices may differ; verify with local ethical review if conducting research.
