Background: The efficiency and productivity of dentists are affected due to musculoskeletal disorders. Efforts should be made to monitor and reduce these disorders so that proper relation is maintained between body and work. Aims and Objectives: This research evaluates and compares the level of creatine kinase (CK) in operators working in ergonomically correct posture and incorrect posture using a newly developed digitalized alarm sensor attached to a dental operating stool. Materials and Methods: A digitalized alarming sensor was attached to half of the operating stools. Blood samples of the operators were checked for CK levels before working on patients and within 13–24 h after the operators have completed their work on patients. Results: The P value was found to be highly significant in operators without digitalized alarming sensors within 13–24 h after completing their work on patients. There was no significant difference in CK levels before patient interaction between the two groups; the presence of the alarm device had a notable impact on CK levels within 13–24 h after work. Conclusion: The group without the alarm device displayed significantly higher CK levels during this postwork timeframe, suggesting a potential association between the absence of the alarm device and increased CK levels among dental professionals.

Introduction: Direct Pulp Capping (DPC) aims to retain the pulp's health by sealing it against microbes and stimulating the formation of a dentin bridge at the exposure site. It has been proven that natural antimicrobial proteins, when used as therapeutics in conjunction with traditional chemotherapeutic agents, have increased efficacy and presumably diminished the incidence of chemoresistance. Hence, the efficacy of Bromelain with Biodentine and Biodentine as isolation materials for DPC will be evaluated and compared in the present study. The success and durability of DPC depend on the type of material used. Thus, the present study focuses on evaluating and considering a combination of materials for DPC that can be used in clinical practice. Need for the study: By addressing the limitations of current materials and formulating a novel combination, the present study aims to contribute to the advancement of material science, providing solutions that meet the demands of this era. Such a breakthrough would not only enhance the performance and longevity of materials but also have a significant positive impact on the preservation of pulp vitality, promoting overall well-being and improved outcomes in healthcare applications. Aim: To evaluate and compare the efficacy of Bromelain with Biodentine and Biodentine in isolation as DPC materials. Objectives: The study aims to evaluate and compare the setting time, flow, solubility, compressive strength, adhesion, and radiopacity of bromelain with biodentine and biodentine in isolation. Materials and Methods: An in-vitro study will be conducted in the Department of Conservative Dentistry and Endodontics at Sharad Pawar Dental College and Hospital, Wardha, Maharashtra, India, for a duration of nine months from May 2023 to February 2024. Standard discs of freshly mixed materials (n=10 samples per material) will be prepared. Compressive strength, solubility in distilled water, setting time, flow, radiopacity, and adhesion of Bromelain with Biodentine and Biodentine in isolation will be evaluated and compared in accordance with the International Standard ISO 6876:2001. Results will be analysed using Tukey's Honest Significant Difference (HSD) posthoc test, one-way Analysis of Variance (ANOVA), and student's t-test. [ABSTRACT FROM AUTHOR]

Introduction: Composite resins are considered the pinnacle of esthetic restorations, but they have their own disadvantages, such as polymerization shrinkage, low fracture toughness, and the formation of microcracks, all of which eventually results in failure of the restoration. Fracture toughness is an important factor for failure. Warming the same composites to certain temperatures will show drastic improvements in the above-mentioned flaws, especially the fracture toughness. Need for the study: Therefore, the objective of this study is to evaluate and compare the fracture toughness of three different types of composite resin systems at two different pre-heating temperatures. The study aims to provide valuable information to clinicians in choosing the most appropriate restorative material for posterior composite restorations, which can ultimately improve the treatment's success rate and reduce the risk of complications such as secondary caries, postoperative sensitivity and ultimately restoration failure. Objective: In summary, this study will compare and evaluate the fracture toughness of nanohybrid, micro-hybrid, and bulk-fill composite resins pre-heated at 50 degrees Celsius and 60 degrees Celsius. Methodology: The methodology involves dividing 72 freshly extracted premolars with intact occlusal anatomy and fully developed apical foramina into three main groups based on three different composites and further dividing each group into two sub-groups based on two different pre-heating temperatures, with 12 teeth in each group. Each tooth will then be prepared with a Class-II Mesio-Occlusal-Distal (MOD) cavity and receive pre-heated composite restoration according to its assigned group and sub-group. The prepared samples will be tested for fracture toughness using a universal testing machine. [ABSTRACT FROM AUTHOR]
