[The dimensions of the roots and root canals of human premolars and molars].

Dental roots and channels were measured in 160 premolars and molars on human upper and lower jaws. The longest roots were found in 5-th teeth and shortest in 7-th. The data suggest that dental channels can be extended up to 10 mm. Their maximal widening in upper jaw molars and premolars is 1 mm and in lower premolars 1.2 mm.

[A biomechanical test of the rigidity of pin fixation in the root canals of human premolars and molars].

Three pin designs were under study: cone-like, with hatches, and snake-cranked. Fixation strength to rupture and compression of 1, 2, and 3 pins was examined. Snake-cranked pins were found best of all fixed in the root canal. The force needed to extract 1 pin was 2.92 +/- 0.3 H, for 2 pins 4.23 +/- 0.4 H, for 3 pins 9.64 +/- 0.4 H. To compress 1 pin the force equal to 7.7 +/- 0.4 H was necessary, 2 pins 16.63 +/- 0.1 H, 2 pins 23.73 +/- 0.5 H.
