Instrument sharpness is key to achieving successful periodontal treatment.

Regular personal and professional biofilm removal is key to preventing and treating oral infections.

This is key to effective nonsurgical periodontal therapy and periodontal maintenance.

The complex root anatomy of these teeth poses a distinct challenge during hand instrumentation.

The use of site-specific ultrasonic inserts/tips can help improve the success of nonsurgical periodontal therapy.

Practitioners should self-identify the presence of joint hypermobility and recognize its potential effect on the musculoskeletal system and the effectiveness of periodontal instrumentation.

Complete removal of all subgingival deposits is a challenge, but leaving burnished calculus behind threatens periodontal health.
