ABSTRACT
Objective:
To examine the ultrastructure of resin-infiltrated sclerotic dentine following the application of an all-in-one self-etch dentin adhesive.Methods:
Naturally-occurring, non-carious cervical sclerotic lesions on 10 extracted premolars were bonded using an all-in-one self-etch dentin adhesive(Adper Prompt L-Pop,3M ESPE, St Paul, USA).Artificially prepared wedge-shaped lesions were also made in 10 extracted sound premolars and restored using the same adhesive as the controls. The morphological change of dentin surface conditioned by the adhesive and the dentin-resin interface were studied by SEM.Results:
Most dentinal tubules were obliterated by rod-like sclerotic casts in the non-carious cervical lesion, the sclerotic casts could not be totally dissolved by the self-etch adhesive. After restoration the resin tags were fewer and shorter in sclerotic dentin than those in sound dentin.Conclusions:
Bonding to sclerotic dentin is different from that to sound dentin, and may be compromised by the fewer resin tags.
