Measurement of root porosity (volume of root air space

Environmental and Experimental Botany, 1988
Abstract Root research can benefit under many circumstances from determination of the % fraction of root volume occupied by air (root porosity). Root porosity provides an indication of root reaction or adaptability to environments with insufficient oxygen availability.

[Root canal volume].

Stomatologia, 1990
In this research we used 180 noncarious teeth, 15 from each kind, in which we cut the anatomic crown. After that we weighted the roots, each group separately, before and after the root canal obturation with the technique of lateral condensation of gutta percha and Grossman's sealer.
