RESUMEN
Context: The purpose of this study was to evaluate the efficiency of self-adhering flowable composite with that of a time-tested conventional flowable composite. Since the self-adhering composite reduces chair time and is convenient to use, its clinical behavior was monitored for a year. Aim: This study aimed to evaluate the clinical behavior of self-adhering flowable composite - Fusio Liquid Dentin - in small-sized Class I cavities and also to compare it with conventional flowable composite - Tetric N-Flow - bonded to the tooth structure with fifth-generation two-step-etch-and-rinse adhesive. Subjects and Methods: A total of 60 cavities were restored using flowable composite materials (30 cavities in each group) and evaluated at baseline, 1 month, 3 months, 6 months, and 1 year with modified United States Public Health Service criteria. The statistical analysis for the study was done using Fisher's exact test for intergroup comparison and Chi-square test for intragroup comparison. P < 0.05 was considered statistically significant. Results: Statistically no significant differences were observed in Fusio Liquid Dentin restorations during the recall visits. Statistically significant differences were found in color match evaluated for Tetric restorations during the recall visits. Conclusion: Based on the data acquired, the novel self-adhering composite material demonstrated good clinical behavior. As a result, at this point in the prospective clinical study, the use of Fusio Liquid Dentin to repair Class I cavities is acceptable.
RESUMEN
Paraesthesia of the mental nerve can occur due to various etiological factors. Rarely, dental infections can cause paraesthesia. However, this article discusses two cases of endodontic etiology in the mental nerve region as a causative factor for paraesthesia. In the first case, the patient had severe pain localized to his right mandible, with numbness of his lower lip. Endodontic treatment led to quick regression and resolution of paraesthesia. In the second case, a patient who was referred for retreatment of a mandibular second premolar infection developed profound paraesthesia in the region of the mental nerve distribution following prior therapy. Possible mechanisms responsible for periapical infection-related paraesthesia are discussed here. CBCT imaging may be useful in the diagnosis and management of such conditions.
RESUMEN
Anatomic variations in mesiobuccal root (MBR) of maxillary molars are common. This variation is found to be more common in maxillary first molars as compared to second molars. However, finding three independent mesiobuccal (MB) canals in the MBR of maxillary molars is clinically a rare entity. With the use of magnification, illumination, and cone-beam computed tomography, combined with the skill of the operator, there is an increased possibility of detecting such additional canals. The present case report describes the successful clinical management of a second molar in a 58-year-old female patient having three MBR canals (MB1, MB2, and MB3) with a Vertucci's Type VIII canal configuration and an almost obliterated pulp chamber. The canals were prepared using hand and rotary instruments, followed by obturation. Very few such cases have been documented clinically in the literature.
RESUMEN
AIM AND OBJECTIVES: The aim of the study was to investigate the effect of two different collagen cross-linking agents proanthocyanidin (Grape seed extract [GSE] and 1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide) on the surface topography of etched dentin and microtensile bond strength (µTBS) of resin dentin bond. MATERIALS AND METHODS: Fifty-two sound human 3rd molars were collected, and their occlusal surfaces were ground flat to expose dentin. Dentin surfaces were etched using phosphoric acid and then teeth were randomly divided into four groups, according to the dentin treatment: Group 1: wet bonding technique, Group 2: dry bonding technique, Group 3: 6.5% proanthocyanidin, and Group 4: 0.1M carbodiimide. Scanning electron microscope analysis was done for twenty specimens (n = 5 per group) at ×10,000 and ×30,000 magnification. Remaining 32 specimens were restored with TETRIC N-Bond adhesive systems and resin composite. After 24 h, teeth were sectioned to produce a cross-sectional surface area of 1.0 mm2 and tested for µTBS. STATISTICAL ANALYSIS: Data were statistically analyzed using ANOVA and post hoc least significant difference test (P < 0.05). CONCLUSION: When acid-etched dentin is treated by 6.5% proanthocyanidin (GSE) and 0.1M carbodiimide, followed by application of adhesives, it results in increased µTBS due to cross-linking of collagen fibrils.
RESUMEN
BACKGROUND: The success of direct pulp capping (DPC) depends on the preoperative assessment of pulpal status, intraoperative judgment after pulp exposure, and the biomaterials used to cap the pulp. AIM: The study aims to compare the clinical and radiographic responses of the pulp-dentin complex after DPC with TheraCal LC, Biodentine, and current gold standard mineral trioxide aggregate (MTA) Plus. MATERIALS AND METHODS: Ninety vital permanent teeth with Class I deep carious lesions were randomly divided into three different groups. After the caries excavation, hemostasis was established using sodium hypochlorite at the site of pulp exposure on which the material was placed. Clinical and radiographic follow-ups were performed at 1-, 3-, and 6-month intervals. RESULTS: Overall success rates of MTA Plus, Biodentine, and TheraCal LC were statistically insignificant. CONCLUSIONS: TheraCal LC and Biodentine showed similar success rates when compared to MTA Plus and can be used as an agent in DPC.
