John Kwan, DDS, Robert Gottlieb, DDS, and Suzanne Newkirk, RDH, further explore the use of the Perioscope as a diagnostic tool in the treatment of cervical enamel projections and enamel pearls in a pair of case studies.
Case #1: “Enamel projection with furcation involvement”
by Dr. John Y. Kwan
The below pictures and corresponding video show a tooth with an enamel projection which has developed bone loss. In the video “Enamel Projection,” a Satelec diamond tip was made Magnetostrictive by the Tony Riso Co. and is used to remove the projection and clean into the furcation.

Photo 2 Photo #1 identifies the enamel projection. Photo #2 shows the curved unltrasonic insert removing the projection and cleaning into the furcation.

As the above picture demonstrates, the enamel projection has been removed and the furcation is now clean and clearly defined post instrumentation.

Prior to the Perioscopy System, this area would have required surgical intervention to view and treat.

Case #2
By Dr. Robert Gottlieb and Suzanne Newkirk, RDH
The below pictures and corresponding video show an enamel pearl found on a molar tooth that developed a periodontal infection with a 6mm pocket depth. With Perioscopy, the doctor removed the enamel pearl quickly and efficiently with no post treatment discomfort or downtime for the patient.

Conclusion: We suggest that the Perioscopy System as a diagnostic tool in the detection and treatment of various anatomical factors, such as cervical enamel projections (CEP’s) and enamel pearls may help reduce potential for localized periodontal destruction.
