| 0 | Dentine exposed connects the lingual and buccal slopes of the cusps but all dentine fields remain isolated |
|
| 1 | Dentine exposed connects the lingual-mesial and buccal-mesial and the lingual-distal and buccal-distal slopes of the mesial or distal cusp and one infundibulum is closed |
| |
| 2 | Dentine exposed connects the lingual-mesial and buccal-mesial and the lingual-distal and buccal-distal slopes of the mesial and distal cusp and both infundibula are closed |
| |
| 3 | 1 infundibulum closed and reduced to less than half and the other still open |
| |
| 4 | 1 infundibulum closed and reduced to less than half and the other closed and isolated |
| |
| 5 | 1 infundibulum closed and reduced to less than half and the other closed and not isolated |
| |
| 6 | 2 infundibula closed, not isolated and reduced to less than half |
| |
| 7 | 1 infundibulum no longer recognizable and the other still open |
| |
| 8 | 1 infundibulum no longer recognizable and the other closed and isolated |
| |
| 9 | 1 infundibulum no longer recognizable and the other closed and not isolated |
| |
| 10 | 1 infundibulum no longer recognizable and the other closed and reduced to less than half |
| |
| 11 | Both infundibola no longer recognizable |
| |
| M3 Additional distal element (ADE) | 0 | Not connected with other cusps |
|
| 1 | Dentine exposed connects respectively buccal or lingual sides of the additional distal element with the lingual-distal or buccal-distal slopes of the distal cusps |
| |
| 2 | Dentine exposed connects buccal and lingual sides of the additional distal element with the lingual-distal and buccal-distal slopes of the distal cusps |
| |
| 3 | Dentine exposed connects buccal and lingual sides of the additional distal element with the lingual-distal and buccal-distal slopes of the distal cusps with back fossa well visible |
| |
| 4 | Dentine exposed connects buccal and lingual sides of the additional distal element with the lingual-distal and buccal-distal slopes of the distal cusps with traces of back fossa |
| |
| 5 | Dentine exposed connects buccal and lingual sides of the additional distal element with the lingual-distal and buccal-distal slopes of the distal cusps with back fossa no longer recognizable |
