Table 4 The adapted FDI criteria with their categories and grading

From: Influence of different application protocols of universal adhesive system on the clinical behavior of Class I and II restorations of composite resin – a randomized and double-blind controlled clinical trial

A. Aesthetic properties1. Surface lustre
2. Staining
a. surface b. margin
3. Color match and translucency
4. Esthetic anatomical form
1. Clinically excellent/very good
2. Clinically good
3. Clinically sufficient/satisfactory (minor shortcomings, no unacceptable effects but not adjustable without damage to the tooth)
4. Clinically unsatisfactory/(but reparable)
5. Clinically poor (replacement necessary)
1. Acceptable (1, 2, 3)
2. Not acceptable (4, 5)
B. Functional properties5. Fracture of material and retention
6. Marginal adaptation
7. Occlusal contour and wear
a) qualitatively b) quantitatively
8. Approximal anatomical form
a. contact point b. contour
9. Radiographic examination (when applicable)
10. Patient’s view
C. Biological properties11. Postoperative (hyper-)sensitivity and tooth vitality
12. Recurrence of caries (CAR), erosion, abfraction
13. Tooth integrity (enamel cracks, tooth fractures)
14. Periodontal response (always compared to a reference tooth)
15. Adjacent mucosa
16 Oral and general health
