There are many bioactive materials available to repair these defects. Aim: The purpose of this study was to determine and compare the effect of 25% aluminum chloride solution, 20% ferric sulfate solution, and a 980-nm diode laser, when used for hemostasis, on the dislocation resistance of Biodentine placed to repair furcation perforation. Materials and Methods: This in vitro study was conducted on fifty extracted human permanent mandibular molars, with ten teeth in each group. The stimulated perforations were contaminated with blood, except for one group. The contaminated groups were either treated with aluminum chloride, ferric sulfate, diode laser, or none at all. All the perforations were restored with Biodentine and tested for push-out bond strength. Statistical Analysis Used: One-way analysis of variance and Tukey's HSD post hoc test were applied with a l...

A dentist can address their concerns by understanding their expectation. This cross-sectional study aims to compare and assess the self-perception regarding dental aesthetics between male and female patients belonging to different age groups and economic status. Materials & Methods: A questionnaire consisting of 16 questions was distributed among 200 adult patients belonging to two age groups (18-34 and 35-50 years) visiting the dental clinics. The questionnaire focused on patients' perceptions regarding their dental aesthetics, its effect on the quality of life and treatment needs. Descriptive statistics were tabulated, and for assessing the statistical significance, the chi-square test was applied. Binary logistic regression was applied to relate the dependent variable (age) with the independent variables. Results: Among the 200 participants, 58.0% were satisfied with their...

This study aimed to evaluate the shear bond strength of universal dental adhesives under simulated intrapulpal pressure. Materials and Methods: Forty intact maxillary premolars were distributed into four groups (Group 1 – 3M ESPE Adper Single Bond 2 total etch adhesive, Group 2 – 3M ESPE Single Bond Universal, Group 3 – Prime and Bond universal adhesive, and Group 4 – Ivoclar Tetric N Bond Universal). Adhesive restorative procedures were carried under intrapulpal pressure simulation following which it was subjected to a shear load of 0.5 mm/min. Fracture mode analysis was performed using a stereomicroscope. The data obtained were subjected to ANOVA and Tukey post hoc test with a P < 0.05. Results: Highest bond strength was exhibited by Group 3 (7.01 ± 2.02 MPa) and least by Group 1 (5.36 ± 3.03 MPa). However, there were no statistical differences among the groups. Group 1 and 2 showed mostly cohesive failure, whereas Group 3 and 4 showed mixed failure. Conclusion: The results demonstrated that the experimental universal adhesive agents exhibited comparative shear bond strength when subjected to pulpal pressure. Pulpal pressure has a significant effect on bond strength.
