By John Y. Kwan, DDS, and Suzanne Newkirk, RDH
Case #1: “Cleaning and disinfecting” #12 by Dr. John Kwan
Diagnosis: localized advanced periodontal disease. Initial probing depth 8mm MB, ML Treatment: Micro Ultrasonic/endoscopic debridement with adjunctive antibiotics Azithromycin (Zithromax) 500mg qd x 3d).

As you can see, the extent of bone loss on the mesial is significant, almost to the apex.14 months post treatment:
MB/ML #12 now probes 3mm (above left), Notice the nice bone fill on the mesial surface (above right)
Case #2: “Cleaning and disinfecting” #’s 29-31 by Dr. John Kwan
Diagnosis: Advanced periodontal disease. Initial probing depths 3-11mmTreatment: Micro Ultrasonic/endoscopic debridement with adjunctive antibiotics Azithromycin (Zithromax) 500mg qd x 3d).

As you can see, calculus is visible on the mesial surfaces of both molars and the extent of bone loss mesial of # 30 is significant. 18 months post treatment:

A one-year follow up of a retrospective analysis of patients receiving Micro Ultrasonic Endoscopic Periodontal Debridement shows a dramatic reduction in probing depths in all types of teeth, particularly in deeply pocketed posterior teeth, as the above case demonstrates. Some perioscopy users incorporate adjunctives and or other therapy into their non-surgical protocol, such as Arestin, Emdogain (an enamel matrix derivative), and lasers.
