Simple occlusal diagnosis and treatment using BDORT
In this study, simple method using by Bi-Digital О-Ring Test (OMURA, Y. 19772022, BDORT) showed to determine the correct occlusal vertical dimension and the treatment. In prosthodontics, the Wills method (measurement the distance from the pupil to the angle of mouth is equal to the distance from the lower nasal point to the chin) reveal to determine a guideline for occlusal vertical dimension, but it is exceedingly difficult to determine the appropriate occlusal vertical dimension in practice.

Evaluating fixed prosthodontic treatment complexity in a Nigerian tertiary hospital using the restorative index of treatment need
The study aimed to evaluate the complexity of fixed dental prostheses using the Restorative Index of Treatment Need (RIOTN) system. This descriptive cross-sectional study included patients who received fixed dental prostheses. The complexity of their treatments was assessed using the RIOTN system's fixed prosthodontics treatment assessment component, which evaluates the complexity of fixed prosthodontic treatments, including intra coronal restorations, veneer restorations, and extra coronal restorations (including pontic units). A total of 60 patients received 74 fixed prostheses. After applying modifying factors, 58.1% of cases were graded as complexity grade 1, 25.7% as grade 2, and 16.2% as grade 3. Modifying factors were present in 10.8% of patients, with a retching tendency being the most common (37.5%). The study found that most patients (58.1%) required fixed dental prostheses with a complexity grade of 1, indicating a relatively straightforward treatment. The presence of a retching tendency (37.5%) was the most common modifying factor, which can increase treatment complexity. This assessment highlights the importance of evaluating the complexity of fixed dental prosthesis treatments to ensure optimal patient care and outcomes. Fixed dental prostheses are a common dental procedure that requires accurate diagnosis, radiographic examination, clinical assessment, and technical expertise for successful outcomes. The complexity of these treatments varies widely, and assessing it is essential to ensure optimal patient care and outcomes.

Effect of Different Surface Treatment on Hardness of Dental Alloys
Objectives: Investigate different surface treatments on hardness of specimens produced by CAD-CAM milling techniques and selective laser melting technique. Materials and Methods: Thirty disc-shaped specimens were put into three main groups. Each group has ten examples of Co-Cr metal that were made of different materials. There were three kinds of milling: hard, selective laser melting (3D printer), and soft. Everything was cut up into 15 mm wide pieces that were 3 mm thick so that they could be used for more tests. The last step was to finish them off and make their surfaces smooth with a diamond grinder. A scanning electron microscope (SEM) was used to look at one example from each group and figure out how the surface of the metal frame was made. We tested how hard specimens were. We used the independent sample one-way ANOVA to determine differences. Results: Hardness tests for all test groups in the study showed that 3D printing usually gave the best hardness in the control and sandblast groups. Hard cutting gave the most hardness in the Laser group. We used One- and Two-way ANOVA and Levene's test to look at the data statistically. All the tests had p-values of 0.001, which means that the hardness values for each milling type are very different from one another. Conclusion: 3D printing generally resulted in the highest hardness values, and the control and sandblast groups hard milling showed superior hardness in the Laser group.

Acrylic Denture Basis’ Long-Term Colour Stability
Objective: This study investigated how staining solutions affected the acrylic denture bases' colour stability. Materials and Methods: Fifty-six samples of acrylic denture base (hot and cold) were submerged in distilled water for control and three staining solutions. A spectrophotometer was utilized to measure colour Before immersion, every sample's initial colour value was noted. Following a 24-hour, one-week, and two-week immersion period, colour change values were calculated. Results: Hot coffee was the most preferred beverage, showing strong significance over both time periods (P = 0.002 for 24 hours, P = 0.013 for 1 week). This indicates a consistent preference for hot coffee. Karak and hibiscus demonstrated increasing preference over time, especially in their hot forms (P = 0.001 for hot Karak, P = 0.006 for hot hibiscus). This suggests that these drinks become more favored as habits develop. Comparison between 24-hour and 1-week data showed that coffee remained stable in preference, while Karak and hibiscus became more preferred over time. Conclusion: The denture base's discoloration rose in direct proportion to the immersion time, and the instant coffee solution was discovered to be the most chromogenic staining solution. To maintain the color stability of acrylic dentures, users should adopt good oral hygiene practices and minimize prolonged exposure to these beverages.
