Feigal’s table for clinical success of fissure sealant on occlusal surface

Rating	Assessment Type
A. Marginal Integrity
0	Restorative material adjacent to the tooth and not detectable with an explorer
1	Margin detectable with the explorer
2	Crevice along the margin of visible width and depth
3	Crevice formation with exposure of central fissure
B. Marginal Discoloration
0	No color change at the tooth-sealant interface
1	Discoloration noted along the margin in one area
2	Discoloration noted along the margin in multiple areas
3	Severe discoloration with evidence of penetration and leakage
C. Anatomical Form
0	Harmonious and continuous with occlusal form and structure
1	Change in anatomical form but all pits and fissures covered
2a	Loss of sealant from one or two pits or accessory grooves (partial loss), but no need to repair or replace sealant
2b	Loss of sealant from pits or accessory grooves (partial loss), with a need for replacement or repair of the sealant
3	Loss of sealant from all pits (total loss)
7	Partial loss due to occlusion
9	Bubble (not connected with the margins)
