Initial perio charting (above left), Pretreatment radiograph (above right)

As you can see, the extent of bone loss on the mesial is significant, almost to the apex.

Initial perio charting (above left), Pretreatment radiograph (above right)

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.

Pocket depths are now 2-5mm (above left), Notice the nice bone fill on the mesial of both molars (above right)

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.
