Endodontic Release System for Apexification with Calcium Hydroxide Microspheres

Abstract

A supplemental appendix to this article is published electronically only at http://jdr.sagepub.com/supplemental. AbstrActThe use of calcium hydroxide (CH) as an intracanal medicament for apexification is widespread. However, because of a short residence time in the root canal, the CH must be refreshed frequently, increasing the number of appointments required and leading to patient non-compliance. We hypothesized that a core-/shell-structured CH microsphere system would lead to sustained slow release of calcium and hydroxide ions of CH for long periods of time, eliminating the need for multiple visits for apexification. In this study, calcium hydroxide microspheres (CHMSs) with a core/shell structure were prepared by an emulsion method. The CHMS shell was composed of alginate, which was crosslinked by the Ca 2+

Comparision of Healing of Periapical Lesion with Different Intracanal Medicament Using Mineral Trioxide Aggregate as Apical Barrier

“…[16] The artificial apical barrier technique is a contemporary approach for managing open apices cases. This technique uses a apical barrier material that is placed at the open apex facilitating obturation by confining it within the canal.…”

Vertical root fracture associated with prolonged use of calcium hydroxide during apexification. A case report

“…There are studies showing that the time required for the formation of the apical barrier using calcium hydroxide can be long, up to about 20 months, and it is necessary to consider other factors such as age, the presence of symptoms, which can affect the time taken for apical barrier formation even extending it [5][6] .…”

“…Many materials such as calcium hydroxide, zinc oxide, calcium phosphate and MTA have been used to stimulate apical stop formation during apexification. For this purpose, multiple sessions are necessary for replacing the material but the outcome is usually favorable [4][5][6] .…”

The Management of Crown Fracture of Immature Teeth by MTA and Calcium Hydroxide: Case Reports

“…This technique was the mainstay for the management of immature apices for over half a decade [16]. Ca(OH) 2 is the most widely accepted material, due to its biological and antimicrobial properties, such as reparative dentin to bridge a pulp exposure, induction of hard tissue formation and ability to stimulate the formation of new bone, healing of large periradicular lesions and inhibition of root resorption [17][18][19]. Ca(OH) 2 dressing helps to eliminate the microorganisms and inactivates toxic products [20,21].…”
