“…There are different terms used to describe the seal of the root canal system. A proper term that should be use is a “Fluid-Tight seal” or “Fluid Impervious seal” because the seal of the root canal are commonly evaluated against fluid leakage – a parameter used to approve or disapprove obturation materials and techniques [ 2 – 4 ]. The role of root canal sealer along with the gutta percha is crucial to fill the interface between the dentin wall and obturating material to bring off this fluid tight seal as the sealer contacts the root canal wall, flow into the complex anatomy of root canal system like accessory and lateral canal, voids, spaces, isthmus, deltas and also penetrates into the dentinal tubules.…”

Aim To compare and evaluate the sealing ability of four different commercially available sealers to provide seal against the dye penetration test using a stereomicroscope-an in-vitro study. Material/Method 80 extracted single rooted mandibular premolar with single canal were used in this study. The samples were divided in 4 groups (20 in each) based on sealer. Group I (Diaproseal), Group II (apexit Plus), Group III (MTA Fillapex) and Group IV (Bio-C). The samples were analyzed using a stereomicroscope and data analysis was done with one-way Anova And post hoc Tukey’s test. Result The mean dye penetration score was 1.2400 ± 0.778 mm for Group I. 2.6000 ± 0.897 mm for Group II, 4.2000 ± 0.923 mm for Group III and 4.225 ± 2.055 mm for Group IV. One-way Anova analysis shows that intergroup comparison was statistically significant between the four groups. The post hoc Tukey’s test reveals that the difference was statistically non-significant between group III and group IV. Conclusion It was concluded that between the four groups the Group I (Diaproseal) showed the least dye penetration followed by Group II (Apexit Pus), Group III (MTA Fillapex) and then Group IV (Bio-C), where there was no significant difference between the Group III (MTA Fillapex) and Group IV (Bio-C).

“…Feedback from faculty is generally regarded as an important aspect to improve student's knowledge and skills [16]. Faculty feedback following SA helps students familiarize themselves with faculty expectations and comprehend course aims and assessment norms [17][18][19]. The literature revealed that constructive faculty feedback favourably impacts student's self-confidence; and hence, SA has been accepted in several fields [20][21][22][23][24][25][26].…”

Background Self-assessment (SA) is an interactive course that endorses the accomplishment of learning objectives through learners’ identification of insufficiencies in their didactic knowledge and pre-clinical skills. This study was planned to determine whether there is any improvement in the faculty assessment (FA) score following the implementation of SA in the Pre-clinical Conservative Dentistry Course. Methods Fifty-four first-semester dental students were given an introductory lecture followed by a demonstration for Class I Cavity Preparation in typhodont mandibular first molar. At the end of the demonstration, the Scoring Rubric (SR) was explained point-wise in the prepared cavities. During the next session, all students performed Class I cavity preparation and they were given an assessment sheet to enter their scores (SA1). All teeth were evaluated by the Grading Faculties in a blinded manner (FA1). Each participant was explained the difference in their respective SA1 from FA1 and their queries were resolved individually. During the next sessions, Students and Grading Faculties followed the same protocol and scores were recorded as SA2, FA2, SA3 and FA3. Results The mean score of SA1 was significantly higher than that of FA1 (p < 0.001). However, no significant difference was obtained between SA and FA in the second (p = 0.352) and third (p = 0.434) assessments. In contrast with first assessment, mean marks obtained in FA were higher compared to SA in both second and third assessments. There was a statistically significant improvement in mean marks obtained by the students over time (p < 0.001). Conclusion SA endorsed student-faculty communication and enhanced student’s poise and technical skills in operative pre-clinical dentistry.

BACKGROUND: Polymethyl methacrylate (PMMA) is a commonly used denture base material, but susceptibility to fracture under functional loading remains a challenge. OBJECTIVE: This preliminary screening study aims to investigate the potential of sericin and fibroin as reinforcing agents in the PMMA denture base material. METHODS: The flexural and impact strengths of PMMA incorporated with 0.01% sericin, and 0.01% each of sericin and fibroin, were evaluated. The control group consisted of PMMA without any additives. The maximum load and energy required to break the samples were measured. Statistical analysis was performed using one-way ANOVA test and Scheffe Post Hoc tests to compare mean values between subgroups. RESULTS: The results indicated significant improvement in the flexural and impact strengths of PMMA with the addition of sericin and fibroin. The subgroups with 0.01% sericin, and 0.01% each of sericin and fibroin, demonstrated higher mean values in load and energy measurements compared to the control group. The statistical analysis confirmed the significance of these findings. CONCLUSION: The addition of 0.01% sericin and 0.01% each of sericin and fibroin to PMMA denture-based resin material significantly increases its flexural and impact strengths. These preliminary findings suggest the potential of sericin and fibroin as effective reinforcing agents in PMMA denture base materials, thereby enhancing their biomechanical properties.
