Summary
This study compared dentin hardness after removing decayed tissue using a conventional bur versus chemomechanical methods (Papacárie, Carisolv). All methods reduced dentin hardness, with no significant differences between them.
Area of Science:
- Dentistry
- Biomaterials Science
- Dental Caries Research
Background:
- Dental caries removal is crucial for preserving tooth structure.
- Conventional mechanical removal and chemomechanical methods are used for caries excavation.
- Assessing the impact of different removal techniques on remaining dentin properties is essential.
Purpose of the Study:
- To evaluate the microhardness of dentinal surfaces after carious tissue removal using a conventional bur, Papacárie, and Carisolv.
- To compare the effects of mechanical versus chemomechanical caries removal on dentin integrity.
Main Methods:
- In vitro study design.
- Microhardness testing of dentinal surfaces.
- Comparison of three carious tissue removal methods: conventional bur, Papacárie, and Carisolv.
Main Results:
- The microhardness of remaining dentin was significantly lower than that of healthy dentin across all tested methods.
- No statistically significant difference in remaining dentin microhardness was observed between the conventional bur, Papacárie, and Carisolv methods (p<0.05).
Conclusions:
- Carious tissue removal, regardless of the method employed, reduces the microhardness of the remaining dentin.
- Conventional mechanical and chemomechanical caries removal techniques demonstrate comparable effects on dentin microhardness in vitro.
