When Instruments are Dull Everything is Harder
The success of non-surgical periodontal therapy relies on multiple factors, one of the most critical being the effective removal of biofilm and calculus through instrumentation. In today’s dental hygiene practice, clinicians commonly use a combination of hand instruments and ultrasonic scalers to achieve this goal. Current evidence supports that both modalities are effective for subgingival instrumentation, with comparable outcomes in pocket depth reduction and bleeding on probing when used independently or in combination (1). Because both approaches are integral to periodontal therapy, instrument performance becomes a defining factor in treatment effectiveness. For ultrasonic instrumentation, efficiency is directly influenced by tip wear. Research shows that a loss of just 1 mm of tip length can reduce efficiency by approximately 25%, while 2 mm of wear can decrease efficiency by up to 50% (2). While monitoring ultrasonic inserts is essential, this publication will focus specifically ...
