Root debridement of molars with furcation involvement using diamond-coatedsonic scaler inserts during flap surgery - a pilot study

In our laboratory, we modified sonic scaler inserts to increase effectivity of root surface instrumentation of molars with furcation involvement durin g flap surgery. The working end of conventional sonic scaler inserts was th ickened ellipsoidally and diamond coated. Inserts with variously angled sha fts were designed in order to facilitate insertion into the furcation. A cl inical, split-mouth study examined the debridement of molars with furcation involvement during flap surgery using either hand instruments or diamond-c oated sonic scaler inserts with 15 patients. Average treatment time was cut by ca. 50%, using diamond-coated inserts as compared to hand instruments f or root surface debridement during surgery. 2 years after surgery, the clin ical parameters had not been influenced by type of instrument used.
