MTA (Mineral Trioxide Aggregate) apical plug is a technique used in endodontic treatment to create a barrier at the apex of the tooth. This innovative solution has revolutionized endodontics by providing excellent sealing ability and biocompatibility. When combined with internal tooth bleaching, the MTA apical plug technique offers an aesthetically pleasing and predictable outcome for discolored teeth. In this article, we will explore the MTA apical plug technique along with its combination with internal tooth bleaching for effective and reliable results.
What is MTA?
MTA is a bioactive cement that has gained immense popularity in endodontic treatments. It is composed of tricalcium silicate, dicalcium silicate, and bismuth oxide. MTA possesses unique characteristics that make it an ideal material for various dental procedures. These properties include exceptional sealing ability, biocompatibility, good marginal adaptation, as well as its ability to promote tissue healing and mineralization.
MTA Apical Plug Technique
The MTA apical plug technique involves the placement of an MTA barrier at the apex of the tooth during root canal treatment. This technique is commonly utilized in teeth with open apices or in cases where conventional root canal filling materials do not adequately seal the root canal system.
This article describes a case in which a 24-year-old girl presented with a palatal sinus tract accompanied by swelling in the area of the maxillary left incisor. At 8 years of age, she suffered a trauma to this area. A crown fracture had occurred and it was restored with composite resin. The patient and her mother told that the tooth was extirpated 4 months ago. The patient did not experience any discomfort, except for an occasional bad taste in his mouth. The tooth was asymptomatic, and the clinical examination revealed physiological mobility and discoloration

The access cavity was drilled using a round carbide bur through the composite core. The pulp chamber was fully accessed and refined using a stainless steel diamond coated ultrasonic tip with and without water spray.

The apical portion of the root canal is prepared to create a space for the MTA apical plug. The size of the apical plug is determined based on the tooth's anatomy and the extent of apical enlargement desired.

The MTA cement is mixed according to the manufacturer's instructions and is then placed in the prepared apical area using a suitable carrier. The MTA cement gradually sets and hardens over time, forming a solid barrier at the apex of the tooth.

After the MTA has set, the remaining root canal is filled with a suitable root canal filling material, such as gutta-percha and sealer.

Conclusions
The MTA apical plug technique, when combined with internal tooth bleaching, offers an innovative and effective solution for endodontic treatment and tooth discoloration. The MTA apical plug provides an excellent seal and promotes tissue healing, while internal tooth bleaching addresses intrinsic tooth discoloration, yielding a desirable aesthetic outcome. By incorporating these techniques, dental professionals can achieve successful results with improved patient satisfaction. further research and advancements in this field will continue to enhance the efficiency and success rates of MTA apical plug with internal tooth bleaching, providing even better outcomes in the future.
