- Brief Summary
This study was conducted to evaluate the effect of the use of apical matrix, with Mineral Trioxide Aggregate (MTA) or calcium hydroxide Ca(OH)2 Apexification on apical healing and calcific barrier formation of immature teeth with non- vital pulp.
- Detailed Description
Conventional root canal filling procedures are challenging in cases of teeth with necrotic pulp, immature apices, and periapical lesions because of the absence of natural apical constriction and the presence of moisture contamination. In these cases, the risk of extrusion of the root filling materials and the difficulty in managing apical seals compromise the long-term outcome of treatment.
Management of immature teeth with non-vital pulp were confined to custom fitting the filling material, paste fills and apical surgery. The limited success enjoyed by these procedures resulted in significant interest in the phenomenon of establishment of an apical barrier like apexification or continued apical development. Apexification defined as a procedure to induce a calcified barrier in a root with an open apex and necrotic pulp Traditionally, the most commonly used material for apexification is Ca(OH)2 .Despite the high success rate of The long-term Ca(OH)2 apexification , there are several disadvantages to this technique; Length of time for induction of apical hard tissue barriers. Incomplete apical hard tissue barriers because of vascular inclusions.To avoid the challenges associated with long-term Ca(OH)2 apexification procedures, a non-surgical, one-step apexification using MTA as apical plug.
The major problem in cases of a wide open apex is the need to limit the apexification material at the apex, thus avoiding the extrusion of a large amount of material into the periodontal tissue. The use of a matrix is advisable since its placement in the area of bone destruction provides a base on which the sealing material can be packed .
This randomized controlled trial study was carried out to compare the clinical and radiographic outcome of Ca(OH)2 and MTA with or without internal matrix in non-vital immature maxillary incisors.

Group Intervention Description MTA Apexification with apical matrix Apical matrix An internal (apical) matrix was used as a base for condensation of MTA apical plug, a pieces of (4X4mm) of resorbable collagen membrane (Biocollagen; Bioteck:Turin, Italy)were compacted toward the apex with premeasured suitable size schilder plugger. Moist cotton pellet was placed over the MTA followed by application of coronal seal. After 48 h, the set of the MTA was checked and final obturation of the root canal was done MTA Apexification with apical matrix Apexification An internal (apical) matrix was used as a base for condensation of MTA apical plug, a pieces of (4X4mm) of resorbable collagen membrane (Biocollagen; Bioteck:Turin, Italy)were compacted toward the apex with premeasured suitable size schilder plugger.

After 48 h, the set of the MTA was checked and final obturation of the root canal was done Ca(OH)2 Apexification Ca(OH)2 Apexification was performed with calcium hydroxide. calcium hydroxide dressing was applied directly against the open apex .The canals were back filled with Ca(OH)2 dressing, followed by proper coronal seal. Patients were recalled every 3, 6 and 12 months for evaluation clinically and radiographically. Once the calcific apical barrier was detected the root canals were then obturated and final restoration was done.

Ca(OH)2 Apexification with apical matrix Apexification Treated by condensation of calcium hydroxide dressing against an internal matrix , a piece (4X4mm) of resorbable collagen membrane (Biocollagen; Bioteck:Turin, Italy) was gently compacted toward the apex before insertion of Ca(OH)2 dressing, followed by proper coronal seal.
