Re treatment of lower right second molar

Preoperative RVG of lower right second molar

In this RVG of lower second molar , we can easily visualize post obturation restoration is fractured. Lateral condensation in the distal canal is very poor . In mesial lingual and buccal canal , we can hardly notice any gutta percha point inside it.In the middle third of the mesial root , file is fractured . So we decided to go for re rootcanal treatment with the same tooth.

Postoperative RVG of lower right second molar

In this above RVG , we can eaisly make out the fractured part of file is bypassed and successful obturation is done with the distal as well as mesial canals followed by temproray restoration with ZOE cement.

Proerties and uses of MTA

Properties

Ø  ph initial 10.2 & rises to 12.5 when set

Ø  Highly alkaline

Ø  Setting Time is 2 hrs 45min

Ø  Compressive strength 40 mpa immediately

   & 70 mpa after 21days

Ø  MTA has calcium oxide which reacts with water to form calcium hydroxide

Ø  This causes formation of calcite crystals & & fibronectin

Ø  These act as initiating step for hard tissue barrier formation

Ø  Fibronectin promotes cellular adhesion & differentiation

Uses

Ø  Repair of perforation

Ø  Root end filling material

Ø  Pulp capping agent

Ø  Apexification

Ø  Apical third filling material

Ø  Obturating material
