In vitro effectiveness of a chemo-mechanical method for caries removal

Area of Science:

• Dentistry
• Cariology
• Microscopy

Background:

• Dental caries is a prevalent oral disease requiring effective removal methods.
• Traditional rotary instruments can cause collateral damage to dentine.

Purpose of the Study:

• To evaluate the efficacy of chemo-mechanical caries removal.
• To compare it with conventional rotary methods using histological and SEM analysis.

Main Methods:

• In vitro study on 45 human teeth with dentinal caries.
• Carisolv chemo-mechanical method used on 30 teeth.
• Conventional rotary instruments used on 15 teeth.
• Light microscopy and scanning electron microscopy (SEM) for analysis.

Main Results:

• All surfaces were clinically caries-free post-treatment.
• Chemo-mechanical method resulted in 53% bacteria-free dentine tubules.
• Conventional method resulted in 87% bacteria-free dentine tubules (p>0.05).
• SEM revealed distinct dentine topography differences between methods.

Conclusions:

• The chemo-mechanical method is an efficient approach for carious dentine removal.
• Histological and SEM analyses support its efficacy.
• Further research may explore clinical implications of differing topographies.
