Summary
New PER-IO-TOR instruments offer efficient root surface planing and protective abrasion, comparable to manual instruments. These dental tools provide an effective alternative for root surface treatments, minimizing abrasion.
Area of Science:
- Periodontology
- Dental instrument technology
- Biomaterials science
Background:
- Root surface debridement is crucial for periodontal therapy.
- Manual instruments are standard but can be challenging in complex anatomy.
- Novel instrumentation aims to improve efficiency and reduce root surface trauma.
Purpose of the Study:
- To evaluate the efficacy of PER-IO-TOR instruments on root surfaces.
- To compare the planing and abrasive properties of PER-IO-TOR instruments with manual curettes.
- To assess the potential of PER-IO-TOR instruments as an alternative to manual instrumentation.
Main Methods:
- In vitro study using extracted human teeth.
- Root surfaces treated with PER-IO-TOR instruments (TOR 1-4) and Gracey curettes.
- Surface examination using Scanning Electron Microscopy (SEM).
- Quantitative analysis of removed root surface substance using mechanical profilometry.
Main Results:
- PER-IO-TOR instruments demonstrated efficient surface planing and protective abrasion.
- Instrument TOR 3 showed comparable results to Gracey curettes.
- Both PER-IO-TOR instruments and manual instruments exhibited minimal root surface abrasion.
Conclusions:
- PER-IO-TOR instruments possess effective planing properties similar to manual instruments.
- These instruments cause minimal abrasion, making them a safe alternative.
- PER-IO-TOR instruments are suitable for both accessible and inaccessible root surfaces.
