Abstract EN
Aim.
To measure and validate the permeability of pressure changes in correlation to different root filling techniques.
Methods.
Eighty extracted single-rooted teeth were randomly assigned to one of eight groups of ten teeth.
Following standardized instrumentation and irrigation, root canal fillings were performed using either cold lateral condensation, a warm carrier-based gutta-percha obturation technique, a warm carrier-based Resilon, or warm gutta-percha compaction with the downpack/backfill technique.
After insertion of a pressure sensor within the pulp chamber ten teeth of each group then underwent simulated dives with pressure measurement and the other ten a dye penetration test during simulated dives to 5.0 bar.
Differences were analyzed statistically (P<0.05) using one-way analysis of variance (ANOVA).
Results.
When the warm carrier-based gutta-percha obturation technique and vertical gutta-percha obturation techniques were used, there was significant lower intrapulpal pressure to experimental chamber pressure (P>0.05).
When cold lateral condensation or carrier-based Resilon as used, pressure was sometimes almost completely equalized.
Conclusions.
Warm gutta-percha obturation techniques provide a largely pressure-tight seal whereas the Resilon obturation technique and cold lateral condensation appear to be unsuitable to pressure changes.
