Aim:
Although dentine is a dynamic sub-stratum of the tooth, it seems correct to say that as far as etching and bonding to the sclerotic dentine is concerned, there are different micro-morphological aspects to be analysed in comparison to those on the healthy dentin.
Methods:
This paper seeks to analysis the interface between the dentin and the adhesive bonding material resulting from in vivo placement of a 5(th) generation dentin bonding system on the base of cavities in 8 teeth. The teeth were removed for periodontal or orthodontic reasons and then examined by scanning electron microscopy.
Results:
The results confirm the notable complexity of the dentin-adhesive interface that is developed or formed in-vivo and is due to the different state in which the dentine is found (healthy or sclerotic).
Conclusion:
It is underlined that the passage from the state of healthy to sclerotic dentin is very fast.
