Maxillary Lateral Incisor

This paper reports a case of gemination in a maxillary lateral incisor with two root canals and crown-root dilaceration. A 16-year-old male patient was referred for endodontic treatment of the maxillary left lateral incisor and evaluation of esthetic and functional complaints in the anterior region. The patient reported trauma to the anterior primary teeth. There was no spontaneous pain, but the tooth responded positively to the vertical percussion test and negatively to the pulp vitality test. Clinical examination showed esthetic and functional alterations and normal periodontal tissues. CBCT imaging confirmed the suspicion of gemination and crown-root dilaceration and also revealed the presence of two root canals and periapical bone rarefaction. The root canals were instrumented with Reciproc R40 and 1% NaOCl irrigation and were filled by lateral condensation of gutta-percha and AH Plus sealer. The tooth was definitely restored with composite resin to recover esthetics. Continued follow-up over 6 months has shown absence of pain or clinical alterations as well as radiographic image suggestive of apical repair.

Background: This work aimed to evaluate the efficacy of sonic agitation of a binary mixture of solvents (methyl ethyl ketone/tetrachloroethylene) on filling remnants removal and compare the effects of solvent agitation with the enlargement to the next instrument size. Methods: Twenty-four mandibular incisors were prepared with ProTaper Next (X1, X2) and obturated with the single-cone technique and AH Plus sealer. The teeth were retreated with ProTaper Universal Retreatment and ProTaper Next and divided into two groups (n = 12) according to the final instrument (X3 or X4). All canals were submitted to a supplementary procedure consisting of a mixture of solvents―methyl ethyl ketone/tetrachloroethylene, agitated with EndoActivator. The volume of filling remnants was assessed through micro-computed tomography in the apical 5 mm. Statistical analysis was performed with a significance level of 5%. Results: The supplementary procedure of agitation of the solvent mixture was beneficial in both groups (p < 0.05). There were no statistically significant differences between canals re-prepared until X4 and canals re-prepared until X3 plus solvent (p > 0.05). Conclusions: An additional step with a two-solvent solution potentiated by EndoActivator showed to be very effective for the removal of gutta-percha and resinous sealer remnants from apical root canals of mandibular incisors, avoiding further enlargement.

ABSTRACT Aim The aim of this in vitro study was to evaluate the apical seal obtained with four root canal sealers AH 26, Sealapex, Endoflas FS and AH Plus, with lateral condensation. Materials and methods Sixty root canals were prepared using the step-back technique. The specimens were divided into four experimental groups of 12 teeth and two control groups of 12 teeth. The experimental groups were obturated by laterally condensed gutta-percha with one of the tested sealers and control groups were obturated without any sealer. Methylene blue dye penetration with centrifuging method was used to evaluate the apical sealing ability. The quantitative apical leakage of each specimen was measured after 2 weeks. Results The results showed no significant differences between all groups except between AH Plus and Endoflas FS (<0.05). AH Plus showed significantly less leakage than Endoflas FS. Conclusion AH Plus showed the least leakage compared to AH 26, Sealapex and Endoflas FS. How to cite this article Joseph R, Singh S.

Maxillary Lateral Incisor

Dental agenesis of the maxillary lateral incisor is a frequently seen anomaly in children and teenagers nowadays. It can alter the esthetics as well as the functions in the frontal area of the maxilla and therefore, early detection and therapy would be beneficial. The treatment often implies an interdisciplinary approach between orthodontics and implantology. One of the particularities of this kind of treatment is given by the distal angulation of central incisor’s root, which invades the space required by the dental implant. Any treatment plan should begin with a thorough radiographical analysis of the space and morphological particularities of the central incisors.

Root Canal System

The proper knowledge of the root canal system anatomy is crucial to perform successful endodontic treatments. Maxillary lateral incisors usually have a single root. However, aberrant canal configurations of this tooth have been reported in the literature. The clinician should be aware of the difficulties arising from this more complex root canal anatomy and should be able to manage them. A rare case of a maxillary lateral incisor with three root canals is presented in this article; the challenge of diagnosis and treatment in similar situations is also discussed.

Objective. To compare the efficacy of ProTaper retreatment files in removing three different obturating materials.Study Design. Forty-five human, single-rooted premolars were divided into three experimental groups. Group 1 was obturated with gutta-percha and AH Plus sealer, Group 2 was obturated with gutta-percha and zinc oxide eugenol sealer, and Group 3 was obturated with GuttaFlow. Retreatment was done using the ProTaper universal rotary retreatment files. Root halves were visualized using magnifying loops at 3X magnification and optical stereomicroscope at 10X magnification. Images were analyzed using AutoCAD 2004 software to calculate area of the remaining debris in the canal. For statistical analysis were used variance test and ANOVA.Results. Total debris/canal area ratio between the three groups showed a statistically significant difference (P<0.001).Conclusion. ProTaper retreatment system did not produce completely clean canals in any of the groups. However, it had the best efficacy towards removing silicon based obturating material GuttaFlow.

The Leap protocol combines the newest and most active association of reciprocal-rotary instrumentation, aluminum insert ultrasonic, and diode laser. The reciprocal-rotary technique consists of Niti instruments used in different motions depending on the stage of the treatment and promotes the balanced cutting effectiveness and reduced risk of fracture files. Moreover, it creates a centered and tapered shape. The aluminum tip for the ultrasonic unit delivers agitation, emulsification, and cavitation of antiseptic solutions that improve the cleaning. The dye and laser use cause the ablation and final disinfection. This paper describes the case of a patient with asymptomatic apical periodontitis in an upper first right molar submitted to endodontic treatment performed with Leap protocol. After conventional procedures, the root canals were prepared by using reciprocal-rotary instrumentation techniques. Between each file a new solution was placed and activated with the ultrasonic handpiece. At the end of instrumentation, the root canals were aspirated, dried with paper points, the indocyanine dye was placed into the root canals and, DaVinci laser was used for 30 seconds. The gutta-percha cones matching the final Niti file were used coated with AH Plus sealer. A periapical radiograph was taken to verify obturation and its anatomical complexity. Six months after the procedure, the patient was asymptomatic, and the radiographic examination showed healthy periradicular tissues. It is concluded that the use of Leap protocol in conventional endodontic treatment was effective, suggesting that this therapy may provide additional benefits to patients when compared to the conventional technique.

Aim: This study evaluated the effect of a sonic device on the bonding of fiberglass posts cemented with a self-etching adhesive combined with conventional cement or a self-adhesive cement to root dentin. Methods: Forty single-rooted bovine incisors were endodontically prepared using a step-back technique. Gutta-percha and AH Plus sealer were used for root canal filling, combined with a thermoplasticization technique. After 1 week, the post space was prepared and the roots were divided into four groups according to the following factors: adhesive system/resin cement (Ambar/ AllCem Core [FGM] and RelyX U200 [3M]) and application mode (manual or sonic). The posts were cemented and the roots were cut into discs and submitted to push-out bond strength (POBS) test. The failure mode was evaluated using a stereoscope at 25x magnification. The data were analyzed statistically using ANOVA and Tukey’s post-hoc test (α = 0.05). Results: The sonically activated RelyX U200 group was superior to the other groups. RelyX U200 manually applicated showed similar results to those of sonically activated Âmbar/AllCem. These three groups outperformed the Âmbar/AllCem manually applicated group. Adhesive failure between dentin and resin cement was the most predominant pattern. Conclusion: Sonic application of self-etching adhesive and self-adhesive cement improved the POBS of fiber posts to the root canal.
