Description

A tooth saved by root canal work still needs a post to hold its crown, and the post's width is a wager: too thin fails, too wide splits the root. Kholoud Saad, Samir Bakry, and Rewaa AboElhassan load-tested in 2023 twenty extracted front teeth rebuilt four ways. The posts were glass-fiber or zirconia, each in a narrow and a wide diameter. A machine then measured the force that broke each tooth.

The wide glass-fiber teeth resisted most; the narrow zirconia least. Yet the spread between groups was not statistically significant. Diameter bent the results, the authors conclude, but the post material's elasticity governed how teeth failed and whether the wreck stayed repairable.
