Summary
A new method accurately measures root surface wear from dental instruments. Erbium, Chromium: Yttrium-Scandium-Gallium-Garnet laser treatment caused less wear than manual scaling, aiding instrument selection in periodontal therapy.
Area of Science:
- Periodontology
- Biomaterials Science
- Dental Instrumentation
Background:
- Understanding root surface wear is crucial for selecting appropriate instruments during periodontal treatment.
- Different instruments cause varying degrees of root surface damage, impacting treatment outcomes.
Purpose of the Study:
- To introduce a novel methodology for quantifying tooth wear resulting from root surface instrumentation.
- To compare the wear produced by different instrumentation techniques on the root surface.
Main Methods:
- Five teeth were sectioned into coronal, median, and apical regions.
- Coronal regions were scaled with curettes; apical regions were treated with an Erbium, Chromium: Yttrium-Scandium-Gallium-Garnet (Er,Cr:YSGG) laser.
- Histological processing and histometric analysis were performed, with statistical analysis using the t test (P < 0.05).
Main Results:
- Er,Cr:YSGG laser irradiation resulted in significantly less root wear (113.37 ± 32.94 μm) compared to manual curette scaling (169.83 ± 24.76 μm) (P < 0.05).
- The developed methodology demonstrated high calibration accuracy in measuring root wear.
Conclusions:
- The proposed methodology is effective, reproducible, cost-efficient, and accurate for measuring root instrumentation wear.
- The findings suggest that Er,Cr:YSGG laser instrumentation causes less root surface wear than traditional curettes.
