RESONANCE COMPATIBILITY BETWEEN ENDOSONIC TIPS AND ULTRASONIC DEVICES OF DIFFERENT BRANDS.
Journal Title: Journal of IMAB - Annual Proceeding (Scientific Papers) - Year 2014, Vol 20, Issue 5
Abstract
The aim of the study was to determine the compatibility of 6 piezoelectric scalers - Mini Piezon (EMS), Pyon 2 LED (W&H), Woodpecker HW-3H (GWMI), Varios 550 (NSK), P5 Newtron (Satelec-Acteon) and DTE HD-7H (GWMI) with 8 types of endosonic tips for separated instruments removal - K-files # 20 and 25 (EMS), ET25 (Satelec), Redo 2 (VDW), CPR-tips 6,7,8 (Obtura Spartan), Proultra Endo tips 6,7,8 (Dentsply-Maillefer), RT3 (EMS), Endo E3 (W&H), E7 (NSK). Methods: Examined and measured was the change in the tips’ displacement amplitude with the power increase of the scalers under total magnification 80x with an optical microscope (Leica MZ6) and an image-measuring software (Klonk Image Measurement). Results: Ultrasonic devices’ compatibility with the examined tips was as follows: Woodpecker – 76,9%, Mini Piezon – 61,5%, Pyon 2 LED - 30,7%, Varios 550 – 83,3%, P5 Newtron – 83,3%, DTE – 33,3%. Lack of compatibility was found in 40,35% of all cases. In 29,82% of the cases of lack of compatibility it was demonstrated as a non-effective vibration, and in the rest of the cases – 10,53% - uncontrolled over-powerful vibration, which was dangerous to use. Conclusion: Endosonic tips should be carefully chosen in accordance with the ultrasonic scaler used.
