Carrier-Based Root Canal Obturation

Thermafil is a named carrier-based filling system. Studies have examined carrier-based and single-cone techniques as different ways to fill root canals.

In curved root canals, a comparative study examined the apical filling characteristics of carrier-based and single-cone techniques. The apical area is the end portion of the canal.

The research includes a comparison in curved canals and a retrospective five-year follow-up after secondary root canal treatment filled with Thermafil.

Single-cone obturation is the alternative used in the curved-canal comparison. It is a separate technique from carrying the filling material into the canal.

The carrier is the feature that distinguishes this method. Research has compared its apical filling characteristics in curved canals with those of a single-cone technique.

A retrospective cohort study followed secondary root canal treatment filled with Thermafil for five years.
