The antimicrobial efficacy of endodontic procedures performed in one-visit (including
a 10-min intraappointment dressing with 5% iodine-potassium-iodide) was compared
with a two-visit procedure (including an interappointment dressing with
calcium-hydroxide paste). Teeth with apical periodontitis (n = 96) were randomly
assigned to either group. Root canal sampling and culturing were performed
before and immediately after instrumentation, and after medication. Initial
sampling demonstrated the presence of microorganisms in 98% of the teeth.
Postinstrumentation sampling showed reduction of cultivable microbiota.
Antibacterial dressing further reduced the number of teeth with surviving
microbes. In the postmedication samples, residual microorganisms were recovered
in 29% of the one-visit teeth and in 36% of the two-visit treated teeth. No
statistically significant differences between the groups were discerned. It was
concluded that from a microbiological point of view, treatment of teeth with
apical periodontitis performed in two appointments was not more effective than
the investigated one-visit procedure.
