Abstract

Synthetic dental fiber tape for fiber reinforcement (FRC) restoration is relatively costly and its availability is still limited in Indonesia, so natural dental fibers have been used as an alternative material. The aim of this study was to assess the effect of impregnation of various fiber tape toward the flexural strength and hardness of FRC. The materials used were natural Bombyx mori silk fibers (Indonesia), dental polyethylene tape (Construct Kerr, USA), dental Quartz tape (Quartz Splint UD, France), dental E-glass tape (Everstick TM, GC, Japan), silane coupling agent (Ultradent, Jordan), and composite resin (Denfil-Flow, USA). Five groups of samples consisted of FRC with various fiber tapes were prepared: unidirectional-silk, braided-silk, quartz, polyethylene, and E-glass. The five groups of FRC were tested to determine the flexural strength and hardness. The results were analyzed by one-way ANOVA, followed by LSD test. The results showed that the highest flexural strength was in the quartz group (496.84 ± 109.14 MPa), while the lowest was in the braided-silk group (139.39 ± 4.30 MPa). The highest hardness property was in the unidirectional-silk group (141.29 ± 25.17 VHN), while the lowest was in the braided-silk group (139.39 ± 4.30 VHN). The ANOVA showed that various fiber tapes significantly influenced the flexural strength and hardness of FRC (p < 0.05). The LSD showed that the unidirectional-silk, braided-silk, and polyethylene groups demonstrated no significant difference. The LSD for hardness showed that the unidirectional-silk group had a significant difference with the other groups (p < 0.05). It can be concluded that various fiber tapes influenced the flexural strength and hardness of FRC. Natural silk fibers showed comparable flexural strength and hardness with the other fiber tapes.

Abstract

Preparation of the root canal system is a crucial step in root canal treatment. Endodontically treated teeth differ structurally from healthy, untreated teeth. This can lead to root cracking by creating pressure on the canal wall, reducing the fracture resistance of the tooth. Different designs, including cross-sectional shape, tip, taper, flute, radial land, helix angle, rake angle, and pitch, can influence the outcome of the root canal preparation and the risk of root fracture. The purpose of this study was to evaluate the fracture resistance of teeth after root canal preparation using three different NiTi rotary files: ProTaper Next (PN), ProTaper Gold (PG), and HyFlex CM (HC). Thirty premolars with a single and straight root canal were decoronated at the cementoenamel junction, leaving 14 mm of the root. The subjects were divided into 3 groups. Group 1 (n = 10) was prepared using PN, group 2 (n = 10) was prepared using PG, and group 3 (n = 10) was prepared using HC. After instrumentation and irrigation, the specimens were subjected to a continuous vertical compressive force (crosshead-speed of 2.28 mm/sec) in order to record the force (in newtons) until root fracture. To describe the surface characteristic of the dentinal root after the preparation, a section fragment from the apical third of the specimens was observed using a scanning electron microscope (SEM) at 2500x magnification. The micrographs were analyzed according to the Hulsman’s method. The results demonstrated that there was a statistically significant difference in root fracture resistance among the three groups. (p = 0.043). The LSD post hoc test indicated that HC showed a higher root fracture resistance (p < 0.05) compared to both PN and PG. In conclusion, the different file systems of PN, PG, and HC instruments generate different root fracture resistance of teeth. In comparison to PN and PG, HC instruments tend to result in increased fracture resistance.

Abstract

Broken files in the root canal system which are not removed may interfere with thorough cleaning of the root canals. As a result, they cannot be hermetically obturated. This imperfect cleaning can leave necrotic tissue which can potentially cause failure in root canal treatment. The purpose of this paper is to describe the management of retrieval of broken files and re-treating root canals in previously treated mandibular left second molars. The retrieval of the broken file used conventional techniques combined with a Satelec ultrasonic scaler to remove the files from the root canal. It was operated under an endodontic microscope, and after retreatment of the root canal, the tooth was restored with final restoration of endocrown. Retrieval of fractured files using conventional techniques combined with Satelec ultrasonic scaler and the root canal re-treatment followed by final endocrown restoration could restore all four tooth functions properly.

Abstract

Complications during root canal therapy, such as perforation, might lead to failure of root canal therapy. A root perforation allows the root canal system and periradicular tissue to communicate, which may affect the treatment outcome. The ability of perforated sealing materials to stop microleakage is also crucial to the success of the treatment. The latest bioactive materials, such as bioactive calcium silicate cement (BCSC) and enhanced resin-modified glass ionomer (ERMGIC), are used. This study compares the microleakage of BCSC and ERMGIC as a material for sealing root perforations at different observation times. Thirty post-extraction premolars, no caries, and single roots were used in this study. Samples were divided into two different groups. The perforation simulation was created using cylindrical fissure round-end burs at a distance of 2 mm from the cervical line. Following the use of BCSC and ERMGIC to seal the perforation, the samples were separated into three subgroups and immersed in a simulated body fluid for different durations in an incubator set at 37°C. As soon as the samples reached the immersion period, all samples were immersed in 1% methylene blue for 24 hours. It was then divided into two parts and examined under a microscope at 50x magnification. The two-way ANOVA test demonstrated no significant variation in the microleakage of the root perforation seal, depending on the material type and the observation time. This study found that microleakage, a material used to seal root perforations, was unaffected by the types of materials used or the length of the observation period.

Abstract

Introduction: Vertucci Type II (root canal) configurations in mandibular second molars are rare. These anatomical variations complicate root canal preparation, irrigation, and obturation. The use of fiber-reinforced direct composite contributes to reinforcing teeth post-endodontic treatment, enhancing fracture resistance, and improving the long-term success of restorations, particularly in posterior teeth subjected to significant masticatory forces. This case report aims to present the management of root canal treatment procedures for a mandibular second molar with a Vertucci Type II configuration, and fiber-reinforced composite restorations through carpeting, and wallpapering techniques. Case Report: A 23-year-old female patient presented to the Conservative Dentistry Clinic, RSGM UGM-Prof Soedomo Yogyakarta, for treatment of her lower left second molar. She reported discomfort in the tooth, which had been previously restored two years prior. Six months before the examination, the restoration fractured causing pain. Although the pain has subsided, food debris often accumulated in the resulting cavity. Root canal treatment was performed using single-cone obturation technique with gutta percha and bioceramic sealer to achieve a hermetic sealing. In addition, restoration utilized polyethylene fiber reinforcement applied with wallpapering and carpeting techniques, combined with short fiber reinforced composite (SFRC) for dentin replacement, to enhance structural integrity and fracture resistance. The patient was monitored for one year. Conclusion: Root canal treatment of mandibular second molars with Vertucci type II configuration emphasizes the importance of understanding root canal anatomy, using CBCT for accurate evaluation. Optimal irrigation and hermetic obturation with a single-cone technique with a bioceramic sealer are crucial for treatment success. Post-endodontic restoration with polyethylene fiber-reinforced composite, incorporating short fiber-reinforced composite for dentin replacement, improves fracture resistance and maintains bond integrity.
