. The purpose of this study was to determine the suitability of different scaling instruments for the debridement of furcations. 12 upper and 12 lower replicated molars with through‐and‐through furcutions were instrumented 3 × with 5 different types of instruments: (i) hand instruments; (ii) hand instruments in conjunction with diamond burrs: (iii) a conventional ultrasonic sealer insert: (iv) a conventional sonic sealer insert; (v) a set of 2 modified diamond coated sonic sealer inserts with different angulated shafts. The plastic replicas were fixed in a manikin head without replicated soft tissues. Following debridement, weight loss and % of instrumented furcation area were assessed. In the ease of lower molars, it made little difference whether they were treated with hand instruments, hand instruments combined with diamond burrs, or diamond‐coated sonic sealer inserts. On upper molars, however, significantly more area was instrumented with the diamond‐coated inserts than with the other instruments. Substance removal was greater with diamond‐coated inserts than with the other devices. In conclusion, an effective debridement of the furcation seems possible only with an odontoplasty, in which a furcation is fitted to the instrument by means of intensive instrumentation, thus leading to substance loss. To improve results with these instruments, further research is necessary.
