Successful Re-endo Treatment With MTA (OrthoMTA)

Objectives: The aim of this study is to introduce clinical experiences of re-endo tx with OrthoMTA (BioMTA, Seoul, Korea).
By comparing it with GP cone, this study explains the advantages of using OrthoMTA, new bioceramic grafting material.
The re-endo treatment with OrthoMTA has shown significantly improved success rate.
Methods: Random 20 retreatment cases were chosen and re-endo treatment with OrthoMTA were done.
OrthoMTA Biofilling was done accordingly:

1. Hydration (PBS) & Mixing
2. Making putty-like MTA((W/P ratio 0.33, Remove any excess water by a 4X4 gauze and sterilized cotton swab.)
3. Loading (into the OrthoMTA Carrier, gentle tapping motion)
4. Delivery - Premixed OrthoMTA paste is introduced into canal system by the OrthoMTA Carrier
5. Gentle plugging
6. Spreading (with reciprocating motion) & Spacing (0.02 tapered, #25 file)
7. Inserting (OrthoMTA Compacter) & Ready to compact (Withdraw the compacter 0.5 mm from the working length and rotate OrthoMTA Compacter at 60 R.P.M.)
8. Apical 1/3 compaction(by OrthoMTA Compacter, ‘Grasping' sense means formation of the apical plug)
9. Middle 1/3 compaction(by OrthoMTA Compacter up and down, round motion)
10. Coronal 1/3 compaction(by the plugger)
Results: Re-endo treatment with OrthoMTA is a very useful and successful process. Randomly sorted 20 cases show high success rate of over 95%. 1 of 20 is apically involved tooth (the last case), has moderate mobility until now. 19 cases out of 20 showed very good development.

The process of filling with OrthoMTA is also easy. New method using MTA carrier, plugger, compactor helps to fill apical portion perfectly.
Obtaining apical patency was very important, and then the rest of grafting processes with OrthoMTA was simple.
Conclusions: Because OrthoMTA is in powder form, MAF is not strict factor. And because overfilled OrthoMTA is not a problem, working length and apical stop is a less concern than cases of GP cone. Moreover, because OrthoMTA has bactericidal and bioactive effect, several NaOCl soaking and application of Ca(OH)2 is not necessary. In fact, almost cases can be done within 2 or 3 visits safely and easily.
Successful results of re-endo tx with OrthoMTA is encouraging our efforts to save more natural teeth. The new paradigm of endodontic treatment using OrthoMTA can make significant development in dentistry.
