Apexification with apical growth and closure using Metapex in a Necrotic Immature Permanent Tooth with Periapical abscess: A Case Report with 16 months follow-up.

Abstract

The purpose of this report is to present the case of a patient wherein apexification of an immature permanent maxillary left central incisor tooth was induced by the Metapex paste (Calcium hydroxide and Iodoform). It has been reported in the literature of dentistry that apexification treatment in teeth with open apex is more than 40 years old. Apexification procedures had been carried out in different ways using various techniques and materials. Regardless of the type of materials used for apexification method by different authors, apexification procedures appear to be the most subtle and accepted clinical practice in non-vital young permanent teeth. In our case, radiographic examination showed the start of apical closure 6 months after the completion of the treatment protocol. The growth of root end and complete apical closure was confirmed 16 months after the treatment, indicating the implausible potential of Metapex to induce apical growth and closure in young permanent tooth with periapical lesion.

Comparative Evaluation of Timing and Closure of Immature Anterior Teeth With Open Apex Using Two Different Regenerative Material: A Case Report-12 Months Follow-Up

“…The main challenge in cases with open apices is to overcome the lack of apical stop, against which endodontic fillers can be compacted. 1 The prevalence of Traumatic Dental Injuries in permanent anterior teeth in India varies from 7.3 to 8.79%. Anterior teeth are at the most susceptible position due to their projection.…”

“…3 Depending upon the vitality of pulp in young permanent teeth, two possible approaches available are Apexogenesis and Apexification. 1,3 Apexogenesis is defined as 'a vital pulp therapy procedure performed to encourage continued physiological development and formation of the root end'. Apexification is defined as 'a method to induce a calcified barrier in a root with an open apex or the continued apical development of an incomplete root in teeth with necrotic pulp'.…”
