Dentin Permeability of Carious Primary Teeth

Abstract

Background: Many in vitro studies have used dentine permeability to evaluate
the efficacy of various restorative and preventative procedures. The easiest way
to evaluate dentine permeability is to calculate its hydraulic conductance (Lp)
using fluid filtration methods. Research has examined electronic hydraulic
conductance measurement methods that give more precise and reliable results
for the permeability of dentine than the classical method. To our knowledge, no
study has examined the dentine permeability of carious primary teeth. Aim: This
in vitro study determined the dentine permeability of carious primary molars
precisely with a new electronic hydraulic conductance measurement system
and compared them with healthy primary molars. Design: The study examined
60 carious and noncarious primary second molars with no restorations, fractures,
or cracks at different root resorption stages. Results: The results showed that
the dentine permeability increased with the severity of caries in primary teeth.
Conclusion: The dentine permeability of carious primary teeth was higher than
that of noncarious primary teeth. Therefore, treatment of primary teeth should be
performed more quickly.
