Ultrasonic instrumentation is an important part of successful nonsurgical periodontal therapy. However, it is not a panacea and requires appropriate power, proper ultrasonic insert/tip (UIT) selection (size and metal mass), variety of fulcrums, and multidirectional strokes. The traditional straight UIT becomes less effective as probing depths increase. The implementation of right- and left-curved UITs can enable clinicians to access difficult-to-reach areas because they can adapt to root structures found in posterior teeth, including furcations, concavities, and depressions.
