Summary
Diamond-coated sonic scaler inserts efficiently remove calculus during periodontal treatment but require careful handling due to significant substance removal. Slim probe-shaped inserts offer safe, gentle plaque removal during maintenance phases.
Area of Science:
- Periodontology
- Biomaterials Science
- Dental Instrumentation
Background:
- Effective calculus removal and gentle root instrumentation are crucial in different periodontal treatment phases.
- Modified sonic scaler inserts, including diamond-coated and slim probe-shaped designs, have been developed for specific applications.
Purpose of the Study:
- To compare the substance removal efficacy of modified sonic scaler inserts against a conventional insert.
- To evaluate the performance of diamond-coated and probe-shaped inserts in different application scenarios.
Main Methods:
- A bench system was utilized to monitor instrumentation parameters like application force and stroke height.
- Aluminum rods and bovine roots were instrumented to assess substance removal depth and volume before and after treatment.
Main Results:
- Diamond-coated inserts removed 30-50% more substance than conventional inserts at high forces (1.0 N).
- A linear relationship was observed between increased force and removed volume for most inserts, excluding slim types.
- Probe-shaped inserts demonstrated minimal substance removal, even with increased pressure.
Conclusions:
- Diamond-coated inserts are highly effective for substance removal and necessitate cautious application due to force-dependent efficacy.
- Slim probe-shaped inserts are suitable for low-risk plaque removal during periodontal maintenance visits.
