Objective: To determine the relationship between facial biotype and smile types in patients attending the “Familydent” dental clinic in Lima, Peru, in 2021. Materials and Methods: The sample consisted of 106 individuals who visited the “Familydent” dental clinic in Lima, Peru, in 2021. Sampling was done in two stages. In the first stage, the individual's age, gender, and facial biotype were recorded using data forms. In the second stage, the smile types were completed after photographing the individuals. Results: 37.7% of the total patients had a leptoprosopic biotype with a low smile type, 48.1% had a leptoprosopic biotype with a medium smile type, and 8.5% had a leptoprosopic biotype with a high smile type. On the other hand, 94.3% of the individuals had a leptoprosopic biotype, 4.7% had a mesoprosopic biotype, and only one patient had an euriprosopic biotype. Regarding smile types, 42.5% had a low smile type, 49% had a medium smile type, and 8.5% had a high smile type. Conclusion: The significance value was (0.337), which is > (0.05), indicating that the null hypothesis is accepted and the alternative hypothesis is rejected. In other words, there is no relationship between facial biotype and smile types in patients attending the “Familydent” dental clinic in Lima, Peru, in 2021.

Compressive strength of three bioceramic cements: mta, biodentine and mta repair hp, - in vitro. lima 2020

Objective: To determine the compressive strength of three bioceramic cements: Mineral Trioxide Aggregate (MTA), MTA Repair HP, and Biodentine in vitro. Methodology: The total sample consisted of 60 blocks, divided into 20 for each bioceramic cement group. The study was experimental, longitudinal, and comparative, where the compressive strength of three bioceramic cements—Mineral Trioxide Aggregate (MTA), MTA Repair HP, and Biodentine—was measured in vitro at 24 and 48 hours after preparation. Statistical analysis was performed using the ANOVA and Shapiro statistical tests. Results: For all three cements, the compressive strength was higher at 48 hours than at 24 hours: MTA 3.69 MPa/2.51 MPa; MTA Repair HP 2.96 MPa/1.47 MPa; and Biodentine 69.97 MPa/51.28 MPa, with a significant difference (p<0.001). A time-dependent difference was observed between MTA and MTA Repair HP (p<0.001). Conclusion: Biodentine demonstrated higher compressive strength compared to MTA and MTA Repair HP, making it a better alternative among calcium silicate-based bioceramic materials.
