“…In particular the mandibular incisors are considerably broader buccolingually than mesiodistally (20), and oval-shaped canals in the apical third were not uncommon (22,23). NiTi rotary files are less effective in the instrumentation of oval-shaped canals (24) and some root canal surfaces may remain untreated. These are favorable conditions for the accumulation of debris and microorganisms (25), are difficult to clean and shape, and become obturated.…”

Objectives. The goal of this study was to determine the sealing ability of MTA, Biodentine, and Fuji IX as root-end materials after ultrasonic retrograde preparation using a dye penetration method. Materials and Methods. Seventy permanent anterior teeth were used in this study. Root canals were prepared using rotary endodontic files, and obturated using the lateral condensation technique. The resection of the root apices was performed perpendicularly to the long axis, and 3 mm deep retrocavities were made by ultrasonic tips. The samples were randomly divided into three experimental groups (N=20) and two control groups (N=5). The root-end cavities were filled with mineral-trioxide aggregate (Rootdent MTA, TehnoDent, Russia) in Group 1, Biodentine (Septodont, Saint Maur des Fossés, France) in Group 2 and Fuji IX GP (GC Corporation, Tokyo, Japan) in Group 3. The retrocavities of the positive control group were left unfilled, while retrocavities in the negative control group were sealed using a flowable composite material. The samples were made transparent, and dye penetration was assessed under a stereomicroscope (x10). The data were analyzed with the Kruskal-Wallis test and the Mann-Whitney U-test. Results. The Biodentine group had a lower mean leakage value than the MTA and Fuji IX groups, and the difference was statistically significant (P<0.01). No statistical difference in apical microleakage was found between the MTA and Fuji IX groups (P>0.05). Conclusion. Within the limitations of this study, it was concluded that Biodentine provides better sealing ability as a root-end material than MTA and Fuji IX. There was no statistically significant difference between the sealing ability of MTA and Fuji IX as root-end materials.

“…The success of endodontic treatment is dependent on hermetically cleaning, shaping and filling the root canal system and achieving an adequate coronal seal. [12][13] Therefore, the technical quality of the root filling is an important factor in treatment success. 14 Root canal morphology evaluation is difficult, considering that the apical root canal is often conical, with multiple parallel walls or narrowing of apical sites.…”

Objectives: To evaluate the grade of apical sealing associated with the root morphology of maxillary first molars with conventional endotreatments using cone bean computed tomography (CBCT). Materials and Methods:The sample included 47 CBCTs. Evaluations were performed independently by one previously trained and calibrated examiner. The grade of apical sealing was evaluated (total sealing, less than 2 mm of sealing, greater than 2 mm unsealed, unsealed and oversealed). Molar angulation according to the palatal plane and the longitudinal axis (vertical, vestibular and palatal), the number of canals, the presence or absence of a second mesiobuccal canal (MB2) and root shape (straight, curved, bayonet, angled, merged, bifurcated) were also assessed. Statistical analysis was performed using the Chi-square test.Results: There were no differences in apical sealing according to root morphology, shape and molar root inclination (p>0.05). A significant association was reported between the presence of MB2 and a buccal inclination of the maxillary first molar (p = 0.048). Conclusions:Root morphology and molar angulation did not affect the apical sealing of maxillary first molars. However, the presence of the MB2 was associated with a buccal inclination of the maxillary first molar.
