In Vitro Effects of External Pressure Changes on the Sealing Ability under Simulated Diving Conditions

Table 1

Pressure differences of the pressure chamber and the pulp cavity for different root filling techniques at 5.0 bar chamber pressure (significance *𝑃<0.05 versus cold lateral condensation).

Group		Δ𝑝 [bar]	SEM
Cold lateral condensation	𝑛=10	1.33	0.9
Carrier-based gutta-percha obturation	𝑛=10	0.09	0.04
Carrier-based Resilon obturation	𝑛=10	1.94	1.32
Downpack/backfill (Gutta-percha)	𝑛=10	0.03	0.02
