The calculus at the second premolar is firmly attached to the tooth surface and it is a tedious process to remove it. In the furcation region the cleaning is performed more or less blind. Various instruments may be used for the cleaning hand instruments, ultrasonic devices or rotating diamonds. These videos were produced by Rolf Attstrom and Danish Dental Association in collaboration with Goof Video, Denmark. No method seems to superior to the other as evaluated on the clinical healing result.
Some studies show that the root surface following the use of rotating instruments become rather raw.
On the palatal surface of the central there is a large defect in the root surface. Probably a fracture which occurred in connection with the accident. Granulation tissue has formed into the defect which is thoroughly cleaned.
