Over the past ten years, Cavitron scaling techniques have been employed extensively in the Armys clinical periodontic and preventive dentistry programs. In the present study, laboratory test procedures and instrumentation for assessment of the effects of ultrasonic scaling on the retention of cast restorations were developed. Extensive testing has shown that high frequency vibrations delivered by the Cavitron do not impair the retention of properly cemented fixed prosthetic devices. Therefore, use of the Cavitron by the military dentist may safely include debridement and scaling of teeth restored by fixed castings. Author
