Synergistic caries Inhibitor y effect of a rematerializing agent and CO2 Laser on human enamel and root dentin

الملخص EN

Objectives: Aiming to determine the potential of combined enamel cream/ laser treatment on enamel and root dentin to inhibit caries.

Methods: A total of 36 premolars were split into two halves; the buccal half received the treatment; enamel cream (Casein phosphor-peptide-Amorphous calcium phosphate CPP-ACP, laser or combination while the lingual halves served as controls.

Results: Enamel cream produced an insignificant increase in surface roughness of the experimental surface as compared to the control surface, whereas laser and combined treatment produced significant increase in surface roughness.

Dentin treatment in all groups did not produce any significant difference as far as surface roughness is concerned.

Polarized light microscopy revealed areas of remineralization varying from focal areas of different densities with enamel cream to wide translucent areas and loss of incremental lines for CO2 laser and combined treatment.

In root dentin, the remineralization extended deep into the dentinal structure filling almost all the demineralization zones for the combined treatment.

Conclusions: Enamel cream and laser were effective in inhibiting caries.

Significant synergistic effect exists for combined enamel cream and laser on inhibition of caries in root dentin.

Enamel cream and laser individually and in combination created surface and subsurface alterations that could provide protection against caries though more evident in root dentin.

The combined therapy seems to be promising in controlling root caries.-
