MTA appears to be a valid option for apexification with its main advantage being, the speed at which the treatment can be completed. A major problem in performing endodontics in immature teeth with necrotic pulp and wide open apices is obtaining an optimal seal of the root-canal system. Mineral Trioxide Aggregate (MTA), has been proposed as a potential material to create an apical plug at the end of the root-canal system, thus preventing the extrusion of filling materials.DOI: http://dx.doi.org/10.3126/jcmc.v5i1.12574

Endodontic treatment of necrotic, immature teeth with open apices can present challenges to debridement, disinfection, and optimal obturation. These teeth may have widely flared canals and thin radicular dentinal walls that are susceptible to fracture. Management of the open apex can be performed using a mineral trioxide aggregate (MTA) apical plug. To ensure a better prognosis in such structurally compromised teeth, internal radicular reinforcement using fiber posts and a self-adhesive cement has been suggested. The present case report illustrates the management of a necrotic, immature maxillary right central incisor in a 10-year-old patient using the MTA apical barrier technique and canal reinforcement using a fiber post.

ABSTRACT Objective: The purpose of this study was to evaluate fracture resistance of teeth with immature apices treated with coronal placement of mineral trioxide aggregate (MTA), bioaggregate (BA), and Biodentine. Materials and Methods: Forty-one freshly extracted, single-rooted human premolar teeth were used for the study. At first, the root length was standardized to 9 mm. The crown-down technique was used for the preparation of the root canals using the rotary ProTaper system (Dentsply Maillefer, Ballaigues, Switzerland) of F3 (30). Peeso reamer no. 6 was stepped out from the apex to simulate an incompletely formed root. The prepared roots were randomly assigned to one control (n = 5) and three experimental (n = 12) groups, as described below. Group 1: White MTA (Angelus, Londrina, Brazil) was prepared as per the manufacturer's instructions and compacted into the root canal using MAP system (Dentsply Maillefer, Ballaigues, Switzerland) and condensed by pluggers (Angelus, Londrina, Brazil). Group 2: The canals were filled with DiaRoot-BA (DiaDent Group International, Canada). Group 3: Biodentine (Septodont, Saint Maur des Fosses, France) solution was mixed with the capsule powder and condensed using pluggers. Instron was used to determine the maximum horizontal load to fracture the tooth, placing the tip 3 mm incisal to the cementoenamel junction. Mean values of the fracture strength were compared by ANOVA followed by a post hoc test. P < 0.05 was considered statistically significant. Results: No significant difference was observed among the MTA, BA, and biodentine experimental groups. Conclusion: All the three materials tested, may be used as effective strengthening agents for immature teeth.

Treatment Alternatives

When pulpal necrosis occurs in immature teeth, one of the treatment alternatives is the creation of an artificial apical barrier through the placement of an apical plug. However, controlling the mineral trioxide aggregate (MTA) during placement has proven difficult. Several studies evaluated the use of resorbable barriers to act as an internal matrix to prevent accidental extrusion of MTA. The aim of this case report was to document the effectiveness of Surgicel as a modified internal matrix for proper placement of MTA during management of immature teeth with necrotic pulp using the apical plug technique. A 12-year-old female patient reported with the chief complaint of a badly mutilated lower right second premolar. The tooth suffered enamel hypoplasia and had a defective coronal structure. It was asymptomatic except for slight tenderness to percussion. Based on the clinical and radiographic findings, a diagnosis of pulpal necrosis with symptomatic apical periodontitis was made. The 3- and 6-month followup showed radiographic evidence of continued root and hard tissue formation. Based on these findings, we infer that Surgicel can be used as a modified internal matrix to prevent extrusion of the MTA into the periapical area and allow for proper MTA placement.

ABSTRACT Objective: To compare the fracture resistance of simulated immature teeth filled with an apical barrier of mineral trioxide aggregate (MTA), Biodentine, and calcium-enriched mixture (CEM). Materials and Methods: Fifty-two single-rooted human maxillary central incisors were used. For standardization, the teeth were sectioned 6 mm above and 9 mm below the cementoenamel junction to simulate immature apex. Simulations of roots into immature apices were carried out using 1.5 mm diameter drills. The specimens were then randomly divided into three experimental groups (n = 13) and one control group (n = 13). In experimental groups, MTA, Biodentine, and CEM were placed to apical 4 mm of the simulated immature roots. The samples were stored at 37°C and 100% humidity for 1 week. A load was applied on the crown of all teeth at 135° to their long axis until fracture. The data were analyzed using one-way analysis of variance and Tukey post-hoc tests. Results: No statistically significant differences were found among MTA, CEM, and Biodentine (P > 0.05), and these groups demonstrated higher fracture resistance than control group (P < 0.05). Conclusions: Using any of the MTA, Biodentine, and CEM as an apical plug and restoring with fiber post and composite resin increases the fracture resistance of immature teeth.

Clinical Cases

Introduction. To present and discuss the results of five clinical cases treated using the revascularization protocol, showing clinical and radiographic monitoring. Necrotic immature teeth with periapical pathology present a challenge to dentists because the techniques used in apexification leave the tooth susceptible to fracture, since the root does not continue to grow in length and the canal walls are thin. Revascularization has emerged as an alternative to resolve these deficiencies, enabling apical closure, continued development of the roots, and thickening of the dentinal walls. Case Series. Five clinically and radiographically diagnosed necrotic immature permanent teeth were treated using revascularization treatment. The therapeutic protocol involved accessing the pulp chamber; irrigating copiously with NaOCl; applying a triple antibiotic paste as intracanal dressing; then provisionally sealing it. After 3 weeks, the canal was cleaned and the apex irritated with a size 15 K-file to induce blood that would serve as a scaffold for pulp revascularization. MTA was used to seal the chamber before final obturation (composite or metallic crown). Conclusion. The discussion of the results leads to debate about different restorative materials and other published protocols.

Immature Teeth

Traumatic injuries to an immature permanent tooth may result in cessation of dentin deposition and root maturation. Novel revascularisation endodontic procedure (REP) has been considered as an option for treatment of immature teeth with damaged pulp tissue. The continuous development of the root and the root canal has been recognised as a major advantage of this technique over traditional apexification approach. Traditional apexification procedures may resolve pathology but have not been able to prove tooth survival due to absence of continued root development and risk of root fracture. A successful REP results in resolution of signs and symptoms of pathology, radiographic signs of healing, proof of continued root development as well as presence of pulp vitality due to the regeneration of pulp tissue in the root canal. Currently, repair rather than true regeneration of the ‘pulp-dentine complex’ is achieved and further root maturation is variable. According to Glossary of Endodontic terms published by American Association of Endodontists, REP’s are biologically based procedures designed to physiologically replace damaged tooth structures, including dentin and root structures, as well as cells of the pulp-dentin complex.1,2 Apexification treatment has been a routine procedure to treat and preserve such teeth for many decades.3 Apexification is the process by which a suitable environment is created within the root canal and periapical tissue to allow for the formation of a calcific barrier across the open apex. Calcium hydroxide [Ca(OH)2] has been the material of choice for apexification as Frank reported its capacity to induce physiological closure of immature pulpless teeth in 1966.4 However, this technique has several disadvantages, including the unpredictability of apical barrier formation and the long duration of treatment, which often requires multiple visits.5 A retrospective study by Jeruphuaan et al.6 has shown a higher survival rate with regenerative endodontic treatment when compared to both mineral trioxide aggregate (MTA) and Ca(OH)2 apexification. The first evidence of regeneration of dental tissues was in 1932 by G.L. Feldman, who showed evidence of regeneration of dental pulp under certain optimal biological conditions.7 In 1971, a pioneer study in regenerative endodontics conducted by Nygaard-Ostby concluded that bleeding induced within a vital or necrotic canal led to resolution of signs and symptoms of necrotic cases and in certain cases, apical closure.8 According to Windley et al. (2005), the successful revascularisation of immature teeth with apical periodontitis is mainly dependent upon: 1. Canal disinfection 2. Scaffold placement in the canal for the growing tissues 3. Bacteria-tight sealing of the access opening.9 The purpose of this case report is to illustrate the outcome of a revascularisation endodontic procedure in a non-vital immature young permanent central incisor.
