Apexification

Apexification is a method of dental treatment to induce a calcific barrier in a root with incomplete formation or open apex of a tooth with necrotic pulp.

The main purpose of apexification includes restoring the original physiologic structures and functions of the pulp-dentin complex of the teeth.

[1] In addition to that, the elimination of the pulp tissue within a tooth, the disinfection of root canal system by using irrigants such as sodium hypochlorite and ethylenediaminetetraacetic acid are the necessary steps to ensure that the purpose of apexification is being met.

[2] The apexification procedure will normally requires several monthly appointments or follow-ups to observe any calcific changes induced at the apex of tooth concerned.

The success rate of applying the traditionally used calcium hydroxide to induce calcific barrier is between 74%-100%.

[6] Due to its physical properties and biocompatibility, MTA has been used in numerous clinical situations other than as a root-end filling.

[7] The setting time of biodentine is shorter as compared with that of MTA, In conclusion, this material is clinically indicated for permanent dentin substitute, direct and indirect pulp capping, pulpotomy, repair of furcation and root perforations, retrograde root-end filling, and apexification.

[7] Proper assessment of the tooth is important in determining an accurate diagnosis in order to formulate an appropriate treatment plan.

However, immature teeth are commonly associated with young patients and pulp testing in children is complex and subjective to nature.

Generally, the treatment paste is allowed to remain for six months before the evaluation for an apical closure.
