Bonding effectiveness of Elsodent’s adhesives Healbond MP and Healbond Max to bur-cut dentin

The bonded interfaces of all micro-specimens were examined for absence of enamel at the corners using the stereomicroscope.

All fractured μTBS micro-specimen pairs (dentin and composite side) were examined using stereo-microscopy to determine the mode of failure, which was recorded either as ‘cohesive failure in dentin’ (D), ‘adhesive interfacial failure’ (I), ‘mixed failure’ (M), or ‘cohesive failure in composite’ (C).

The μTBS of half of the specimens was measured after 1w storage in distilled water at 37°C (without any thermocycling), being referred to as immediate ‘‘1-week’’.

With the remaining half being subjected to 50,000 thermocycles (5°C – 55°C, with 75 seconds total cycle time) being referred as the aged ’’2-months’’.
