Orofacial Esthetic Scale (OES)
Also known as: OES, Orofacial Esthetic Scale (OES)
The Orofacial Esthetic Scale (OES) is a multi-item instrument measuring perception of esthetic quality of teeth, smile, and facial appearance in relation to oral conditions. Developed across multiple research groups in orthodontic and restorative dentistry, the OES quantifies patient and clinician satisfaction with dental esthetics, guiding treatment planning and outcome assessment in cosmetic and orthodontic interventions. The OES captures the patient-centered esthetic perspective, complementing objective dental measurements and enabling assessment of esthetic outcome success.
Key highlights
- Directly captures patient esthetic perception and satisfaction, acknowledging that esthetic outcome success is fundamentally subjective and patient-centered
- Brief and efficient (5-10 minutes); feasible for routine clinical use and large outcome studies without respondent burden
- Responsive to esthetic intervention: demonstrates significant improvement following whitening, cosmetic bonding, orthodontic realignment, or esthetic implant placement
- Enables clinician-patient communication: baseline OES identifies esthetic goals and dissatisfaction; post-treatment OES documents achievement, facilitating shared decision-making
- No licensing or permission barriers; most published OES versions are freely available for clinical and research use

When to use it
The OES is used in restorative and orthodontic clinical settings to assess baseline esthetic dissatisfaction at initial consultation, informing treatment planning and expectation-setting. It is the standard outcome measure in randomized controlled trials and cohort studies evaluating esthetic interventions (tooth whitening, cosmetic bonding, veneers, orthodontics, esthetic implant placement). The OES enables assessment of whether esthetic outcomes meet patient expectations and identifies factors predicting satisfaction. It is also used in health services research examining esthetic treatment outcomes and patient-reported success rates across different treatment modalities.
Strengths & limitations
- Directly captures patient esthetic perception and satisfaction, acknowledging that esthetic outcome success is fundamentally subjective and patient-centered
- Brief and efficient (5-10 minutes); feasible for routine clinical use and large outcome studies without respondent burden
- Responsive to esthetic intervention: demonstrates significant improvement following whitening, cosmetic bonding, orthodontic realignment, or esthetic implant placement
- Enables clinician-patient communication: baseline OES identifies esthetic goals and dissatisfaction; post-treatment OES documents achievement, facilitating shared decision-making
- No licensing or permission barriers; most published OES versions are freely available for clinical and research use
- Esthetic perception is highly subjective; OES scores are sensitive to individual aesthetic preferences, culture, and media influence; identical objective changes produce different patient satisfaction across individuals
- No gold standard OES version: multiple instruments with varying item content and scoring exist, limiting direct comparisons across studies; some versions lack robust psychometric validation
- Ordinal VAS or rating scales treated as continuous in some analyses; nonparametric methods more appropriate
- Does not assess all aspects of satisfaction: patient satisfaction post-treatment depends on communication, treatment efficiency, and cost, not just esthetic outcome; OES captures esthetic perception only

Frequently asked
Why do different patients rate the same smile differently on OES?
Esthetic perception is highly subjective and influenced by personal preference, cultural norms, media exposure, and individual psychology. What satisfies one patient may not satisfy another, even with identical objective tooth appearance. This is why baseline OES is important: it captures each patient's unique esthetic expectations and enables comparison to post-treatment perception.
Should I use clinician rating or patient rating of esthetics?
Both provide value but capture different perspectives. Patient OES reflects their satisfaction and perception—most important for treatment success. Clinician OES assesses objective esthetic quality by professional standards. Discordance between the two is common and clinically informative: low patient OES despite good clinician OES suggests either unrealistic expectations or need for further treatment. Document both.
What is the minimal clinically important difference (MCID) for OES?
Published MCID estimates range from 10 to 20 points on a 0-100 scale. A 15-point post-treatment improvement represents meaningful esthetic enhancement from patient perception. Smaller changes may reflect measurement variability or minor perceptual shifts without clinical significance.
Can OES be used to assess smile esthetics in edentulous patients considering dentures or implants?
Yes, OES has been adapted for prosthodontic outcomes. Baseline OES in edentulous patients reveals dissatisfaction with appearance (no visible teeth, sunken appearance); post-denture or post-implant OES documents improvement. Esthetic outcome success in prosthodontics is highly dependent on patient expectations and OES is useful in this context.
