RESUMO
Background: In the Visakhapatnam District, this study compares the quality management procedures used by public and private hospitals. Knowing how these practices are similar and different from one another can help inform policy decisions and improve the quality of health care. Materials and Methods: A cross-sectional study design was used, and 100 hospitals from both public (50 hospitals) and private (50 hospitals) were included in the sample size. A standardized questionnaire that evaluated different aspects of quality management practices was used to gather the data. Descriptive statistics and inferential tests were used in the quantitative analysis. Results: Significant variations in quality management procedures between public and private hospitals were found. In terms of patient happiness, service responsiveness, and technological use, private hospitals scored better. Regarding accessibility, cost, and equity of healthcare services, public hospitals fared better. Conclusion: The report emphasizes the necessity of focused initiatives to improve quality management procedures in both public and commercial institutions. Collaboration between the two sectors can make it easier to deploy evidence-based tactics and share best practices to raise overall healthcare quality in the Visakhapatnam area.
RESUMO
AIM: This study aims to evaluate the amount of apical extrusion of bacteria during root canal instrumentation using K3XF, Protaper Gold, Edge taper platinum, and Hyflex CM Rotary systems. MATERIALS AND METHODS: Sixty freshly extracted maxillary incisors teeth collected in saline. Access cavity prepared and canals were made free of bacterial and pulp. The teeth were mounted on the bacteria collecting apparatus. Root canals were contaminated with the Fusobacterium Nucleatum (ATCC25586) and dried at 37°C for 24 h. In Group 1 (Control group): No instrumentation was done and biomechanical preparation done in all other groups with Group 2: Hand K-files, Group 3: Protaper gold, Group 4: K3XF, Group 5: Edge taper platinum, and Group 6: Hyflex CM rotary file systems. Then, the extrude was collected, and it is incubated in Mueller-Hinton agar for 24 h and the number of colony forming units were counted and statistical comparison was done using Kruskal-Wallis test and Mann-Whitney U test. RESULTS: Hand K-files extruded more bacteria when compared to other four rotary systems, K3XF file system extruded least number of bacteria. CONCLUSION: All instrumentation techniques extruded intracanal bacteria apically. However, engine-driven nickel-titanium instruments extruded less bacteria than the manual technique. The K3XF rotary file system comparatively extruded less bacteria than other rotary file systems.
