Summary

The EVA scaling system is comparable to ultrasonic and hand instruments for removing calculus and improving root surface quality. However, the EVA system took longer to achieve visual cleanliness compared to other instruments.

Area of Science:

  • Periodontology
  • Dental Instrumentation
  • Scanning Electron Microscopy (SEM)

Background:

  • Root debridement is crucial for treating periodontal disease.
  • Various instruments exist for root surface debridement.
  • Comparing new instruments to established ones is essential for clinical practice.

Purpose of the Study:

  • To compare the efficiency of the EVA scaling system with ultrasonic and hand instruments.
  • To assess calculus removal and root surface quality using SEM.

Main Methods:

  • Extracted teeth were divided into three groups for instrumentation.
  • SEM and light microscopy were used to evaluate debrided root surfaces.
  • Remaining Calculus Index (RCI) and Roughness and Loss of Tooth Substance Index (RLTSI) were employed.

Main Results:

  • No statistically significant differences in calculus removal or root surface quality were found between instruments.
  • EVA system required significantly more time for visual cleanliness.
  • All instruments were capable of minor root damage; hand and ultrasonic instruments left scratches.

Conclusions:

  • EVA inserts are comparable to ultrasonic and hand instruments for root planing.
  • Effectiveness in calculus removal and root surface quality is similar across tested instruments.
