Title

Use of MTA Over Geristore for Repair of Teeth with Furcal Perforations

Clinical Question

In teeth with furcal perforation, does MTA, compared to Geristore, produce more predictable outcomes?

Clinical Bottom Line

MTA and Geristore have similar success rates for repair of furcal perforation.

Best Evidence

PubMed ID	Author / Year	Patient Group	Study type (level of evidence)
23960486	Mehrvarzfar/2010	Teeth with furcal perforations.	In Vitro study
Key results	A hundred extracted mandibular molars were endodontically treated, perforated with a # 4 round bur and randomly divided into 6 experimental groups. These groups were treated either with Amalgam only, or amalgam with Bioglass, MTA only or MTA with Bioglass, Geristore only or Geristore with Bioglass. There were 2 additional control groups-teeth without a filling material and teeth without a perforation, respectively. 72 hours post repair with the above materials, Indian ink was used to evaluate leakage through dye penetration technique and observed under the stereomicroscope. MTA and Geristore have a better sealing ability compared to amalgam, but there was no statistically significant difference in success between the two. Bioglass matrix reduced sealing ability of MTA and Geristore, but affected amalgam insignificantly.

Comments on
The Evidence

Being an in vitro study, evidence was limited. Could not be tested in vivo.

Applicability

Applicable to clinicians with an accidental perforation during endodontic treatment, needing repair. It has been established that while MTA and Geristore have similar repair characteristics, amalgam has significantly lower success rates. Further more, use of Bioglass as a matrix leads to a significant reduction in seal of MTA and Geristore while minimally affects the seal of amalgam. MTA has been proven to allow better bone healing, however, in repair of transgingival cases, MTA is not appropriate because of the long setting time, which allows it to be washed away from the defective site when in contact with oral fluids.
