An In Vitro Evaluation of Leakage of Two Etch and Rinse and Two Self-Etch Adhesives after Thermocycling

Table 2

The 6-point severity scale to evaluate the microleakage.

Scores	Signification
Score = 0	No leakage
Score = 1	Leakage up to the enamel-dentin junction or a depth of 0.5 mm on the radicular wall
Score = 2	Leakage up to the maximum half of the lateral wall (leakage depth ≤1 mm)
Score = 3	Leakage over half of the lateral wall (1 mm < leakage depth < 2 mm)
Score = 4	Subtotal leakage on the whole of the lateral wall (leakage depth = 2 mm)
Score = 5	Total leakage partly or entirely on the pulpal wall of the cavity (leakage depth >2 mm)
