Several studies have confirmed MTA as a potential root-end filling material. The periradicular tissue response in dogs to MTA showed less periradicular inflammation and apical hard tissue formation cementum on the surface of MTA.

Tests on periradicular tissue in monkeys and guinea pigs have led to similar results. The results of these investigations showed that MTA as root-end filling material is associated with significantly less inflammation, better sealing property, periapical regeneration and even cementum formation.

In a case study on a year-old female patient, MTA was used as an apical stop, in a non-vital tooth with an open apex. The root canal space was obturated with ZOE and vertical condensation of gutta percha was done. At a month recall, the tooth was asymptomatic and normal periapical bone architecture was present. The ability to induce apical hard tissue formation, associated with less inflammation compared to other materials calcium hydroxide , makes MTA a good choice as an apical stop in teeth with immature apexes.

Its hydrophilic properties combined with a mineral composition similar to dentin makes MTA a good repair material better than amalgam. Perforation repair is more predictible with MTA than with amalgam and IRM, but only if these defects are repaired before bone destruction has occurred.

A four case report age ranging from 13 to 72 recommends MTA as a good material for treating iatrogenic furcal perforations. Similar results were found in all cases. Follow up recalls at six and 12 months, showed that there were no signs, symptoms or pathology and the radiolucency of the furcation was resolved. Lack of adverse effects after extrusion of MTA into the furcation area confirms its biocompatibility. The results of a four-week trial period are based on staining of perforation sites with methylene blue.

The study shows that MTA leaks significantly less than amalgam and IRM and has less overfilling tendency when compared to the other materials. MTA should be placed with a mm. Exposed dental pulp has the capacity to heal when microleakage and bacterial contamination are not present.

Therefore, an effective pulp capping material should be biocompatible, provide a biological seal and prevent bacterial leakage. Pulp capping has traditionally been performed with Calcium Hydroxide but MTA has now been shown to be more effective. Smillie S, Glasser F. Adv Cement Res. Camilleri J.

Do not refrigerate. MTA being hydrophilic requires moisture to set, making absolute dryness contraindicated. Presence of moisture during setting improves the flexural strength of the set cement. After mixing, the mix should not be left open on the slab as it undergoes dehydration and dries into a sandy mixture.

It should be used immediately after it is prepared. MTA may be placed into the desired location using hand instruments not condensed with excess pressure. Hand condensation is done with the help of a plugger or messing gun. Increase in condensation pressure might reduce the surface hardness. The explanation was that increasing the condensation pressure probably reduces the space required for the ingress of water which is required to hydrate the cement. Applied MTA should be cover by a damp pellet of cotton because for correct setting moisture is required.

Then the tooth should be capped with a hermetic dressing for days. PH: Radio-opacity: 4. MTA thickness of about 4mm is sufficient to provide a good. Antibacterial and antifungal property: This supports the superiority of MTA over formocresol as a pulpotomy medicament.

On direct contact they produce minimal or no inflammatory reaction in soft tissues and in fact are capable of inducing tissue regeneration. MTA showed good interaction with bone-forming cells cells remained viable and released collagen even after 72 hours with good adherence.

Biocompatibility: Glass Ionomer cements or composite resins, used as permanent filling material do not affect the setting of MTA when placed over it. Reaction with other dental materials: 9. It consistently allows for the overgrowth of cementum and also facilitates regeneration of the periodontal ligament. MTA allows bone healing and eliminates clinical symptoms in many cases. Many investigators believe that the hard tissue bridge deposited next to MTA is because of the sealing property, biocompatibility, alkalinity and other properties associated with this material.

They theorized that the tricalcium oxide in MTA reacts with tissue fluids to form calcium hydroxide, resulting in hard-tissue formation in a manner similar to that of calcium hydroxide. But the dentin bridge that is formed with MTA is faster, with good structural integrity and more complete than with calcium hydroxide. MTA also proves to be better at stimulating reparative dentin formation and maintaining the integrity of the pulp.

Mineralization: Clinical applications of MTA It is much superior to the routinely used calcium hydroxide based on the tissue reaction and the amount and type of dentin bridge formed. Aeinehchi et al in reported a 0. The dentin bridge formed with calcium hydroxide was only 0. But this material has been criticized for its tissue irritating, cytotoxic and mutagenic effects.

But this was not of significance since the tooth was later restored with a stainless steel crown. This procedure was used for vital teeth with immature roots. The rest of the cavity is filled with temporary filling material. A wet piece of gauze is placed between the treated tooth and the opposing tooth for hours. This can be done only in compliant patients. Steps involved in the placement of a pulp capping, pulpotomy This procedure involves surgical exposure of the root apex, root resection and plugging the apical foramen with a suitable material that provides complete apical seal, is non toxic, non resorbable, dimensionally stable and radio opaque.

MTA treated teeth exhibited significantly less inflammation, more cementum formation and regeneration of periradicular tissues. This is followed by ostectomy, root-end resection and hemorrhage control.
