Absolutely. But the real advantage comes in using both techniques concurrently.
Our suggestion is that you do a crown down preparation, dress the apex to the size you want and then prepare a seat for the gp to 1mm from the apex using Fine Cut Hand Files to size 35. The important factor is getting a canal that is at least 0.30mm 1mm from the apex.
A recent(April 2005) article shows something that I've known for years, namely that backfilling a canal with cement alone is 24 times as effective as backfilling with gutta percha AND cement. The actual data shows that the average amount of leakage with cement alone is 0.92% of the canal length and the average leakage with gutta percha alone or molten gutta percha with cement was 24% of the canal length.
Actually what the report compared was five scenarios.
The teeth were kept moist and then immersed in India ink and a vacuum was pulled. This removed any air in the gaps between cement and canal wall.
Then the teeth were made transparent with a standard method used in such research.
The now transparent teeth were then examined with a microscope and the penetration of India ink was measured and calculated as a percentage of the canal length.
The results showed that in those teeth with gutta percha in them, the ink penetrated and average of 24% of the canal length.
In those with cement only, the penetration was about 0.92%. Not 92%. POINT 92%.
The authors did not speculate as to why the discrepancy. But I will. It was because of the rebound of the pliable gutta percha after it was packed.
We have been reporting for almost 40 years that cement is entirely adequate as a sealer AND filler. This study tends to confirm our confidence.
