Aim: Assessment of occlusion changes during laboratory phase of relining is essential to evaluate the occlusal discrepancies that could get incorporated in the denture with the use of different relining materials. Since the long term stability and functional success of the denture is heavily influenced by occlusion, an In-vitro study to assess these changes after relining is warranted. The aim of the study is to evaluate the changes in occlusion during laboratory phase of relining procedure. Settings and Design: This is an in vitro study with a total of 30 specimen. Materials and Methodology: A total of 30 maxillary standardized dentures were fabricated after mounting on a semi adjustable articulator. These samples will be divided into three groups based on the relining material used (Autopolymerizing resin, Heat-cure resin, Tissue conditioner). The vertical dimension, Centric contact points and eccentric contact points were measured before and after relining. Statistical Analysis Used: The variables were tested to see if they had a normal distribution using the Shapiro-Wilk test. Parametric distribution was seen for ECP leading to further comparison using one way analysis of variance (ANOVA). Non-parametric distribution was found while testing the VD, CCP leading to adoption of Kruskal-wallis test for comparison of groups. Dunn Bonferroni test was done for VD since results were significant. Results: The results of this in-vitro study showed statistically significant difference with respect to change in vertical dimension in all groups pre and post relining (P = 0.005). The centric contact points showed lesser variation in position when comparing the pre to the post relining phase with the use of autopolymerising resins, whereas heat cure resins and tissue conditioners showed statistically significant difference in the centric point contacts post relining. No statistically significant changes were seen in eccentric occlusion post relining in all groups. Tissue conditioners showed minimum mean changes in eccentric contacts. Conclusion: Within the limitations of this study, the use of autopolymerising resins depicted the most stable results with respect to occlusion, for relining of dentures.

The rise of cloud technology is a big deal for how we share and access data together. It makes working together easier and opens up a ton of new possibilities. But with all this sharing, we need to make sure our information stays safe and that everyone follows the rules we've agreed upon for how services should work. Blockchain technology seems like a good way to keep track of these rules by recording everything in a secure and unchangeable way. However, the usual blockchain systems have some weaknesses. They can still be attacked in ways that could disrupt services, like with DDoS attacks. Plus, the way blockchain reaches agreements can slow things down. However, managing SLAs itself does not ensure the security of the data and user's privacy. Various solutions have been proposed, but none comprehensively address all the issues associated cloud environment. This paper introduces a framework constructed using Hashgraph-based distributed ledger technology to enhance scalability, security, and performance in the tamper-proof logging of all events through smart contracts. This structure aids in detecting points of failure and is applicable for automatic Service Level Agreement (SLA) verification. To safeguard user privacy, protect data from intruders, and ensure semantic security, we have implemented double-layer encryption. A homomorphic encryption technique is employed to preserve user privacy, allowing computations to be performed on the encrypted data. Additionally, AES (Advanced Encryption Standard) is used for secure transportation over an open network to prevent potential attacks such as known-plain-text attacks. The performance of our framework was assessed in terms of latency, CPU usage, and memory usage, while the security aspect was conventionally analyzed.
