Evaluation of pH, Calcium Ion Release, and Dimensional Stability of an Experimental Silver Nanoparticle-Incorporated Calcium Silicate-Based Cement
No full textAn experimental calcium silicate-based root-end filling material incorporated with silver nanoparticles intended for use in periapical surgeries was developed with the purpose to overcome the drawbacks of existing materials and to satisfy the ideal requirements of root-end filling materials. This study was designed to evaluate the physicochemical properties, pH, calcium ion release, and dimensional stability of the experimental cement, and compare the results with commercially available ProRoot MTA (Dentsply). An independent sample test was used to analyze the data. Mean initial pH (immediately after mixing) of the experimental cement was 10.42 ± 0.04 which was higher than that of MTA. However, there was a significant increase in pH of MTA at 1 day, 2 days, and 7 days. Presence of calcium chloride favored the release of calcium ions which was significantly increased in the experimental group at 24 hours. At the end of 30 days, MTA showed a significant expansion when compared to the experimental cement p<0.001. In conclusion, the experimental nanoparticle-incorporated calcium silicate-based cement showed clinically acceptable physicochemical properties
Assessment of sealing efficacy, radiopacity, and surface topography of a bioinspired polymer for perforation repair
No full textBackground Root perforation repair presents a significant challenge in dentistry due to inherent limitations of existing materials. This study explored the potential of a novel polydopamine-based composite as a root repair material by evaluating its sealing efficacy, radiopacity, and surface topography. Methods Confocal microscopy assessed sealing ability, comparing the polydopamine-based composite to the gold standard, mineral trioxide aggregate (MTA). Radiopacity was evaluated using the aluminium step wedge technique conforming to ISO standards. Surface roughness analysis utilized atomic force microscopy (AFM), while field emission scanning electron microscopy (FESEM) visualized morphology. Results The polydopamine-based composite exhibited significantly superior sealing efficacy compared to MTA (P < 0.001). Radiopacity reached 3 mm aluminium equivalent, exceeding minimum clinical requirements. AFM analysis revealed a smooth surface topography, and FESEM confirmed successful composite synthesis. Conclusion This study demonstrates promising properties of the polydopamine-based composite for root perforation repair, including superior sealing efficacy, clinically relevant radiopacity, and smooth surface topography. Further investigation is warranted to assess its clinical viability and potential translation to endodontic practice
Awareness of Symptoms and Risk Factors of Ovarian Cancer Among Healthy Women Aged 18 Years and Above: A Narrative Review
No full textIntroduction: Ovarian cancer is often termed a silent killer due to its late presentation and poor prognosis. Awareness of its symptoms and risk factors is crucial for early healthcare intervention, which can significantly increase survival rates. This review article focuses on awareness of ovarian cancer, the risk factors, symptoms and factors influencing awareness among women.
Methods: Articles published in English between 2009 and 2024 were included, focusing on awareness of ovarian cancer symptoms and risk factors among healthy women aged 18 years and above in a community-based or facility-based study setting.
Results: Overall, awareness of ovarian cancer symptoms and risk factors was low among women. Common symptoms identified included pelvic or abdominal pain, increased abdominal size, fatigue, and unexplained weight loss. Key risk factors were a family history of breast/ovarian cancer, smoking, over 50 years, and ovarian cysts. The studies also highlighted the influence of demographic factors such as education, occupation, marital status, and age on awareness levels.
Conclusion: This review highlights the critical need for impactful interventions to raise awareness about ovarian cancer symptoms and risk factors globally. Increasing awareness is essential for early detection and better management, which can reduce the disease\u27s incidence. Enhanced education and health programs for women are crucial to significantly improve survival rates and overall health outcomes
Health Insurance Awareness and its Socio Demographic Correlates among Fishermen of Dakshina Kannada District, Southern India
No full textBackground: Fishing is a substantial contributor to the Indian economy and Fishermen are subjected to a variety of occupational risks and are at high risk of injury. Health insurance (HI) is a strategy for reducing out-of-pocket expenses during times of illness. Fishermen are subjected to a variety of occupational risks and are at high risk of injury. People with limited resources often lack access to quality health care. Most people obtain healthcare from private providers. This results in catastrophic healthcare costs and the impoverishment of low- and middle-income people. Lack of information about health insurance schemes, budgetary restrictions, and the unavailability of suitable insurance plans customized to their individual needs, the fisherman community frequently struggles to secure health insurance coverage.Methodology: Community-based interventional research among fisherman in the field practice area of medical college in Dakshina Kannada District in Coastal Karnataka. The data was gathered from consented individuals.Results: The majority of the study participants 248 (75.2%) were men between the ages of 40- 50 years 101 (30.6%). A large part of study population belonged to nuclear households 260 (78.8%), with a monthly income of less than or equal to INR 10,000/- among 209 (63.3%) participants. Intervention on health insurance led to increase in awareness and entitlement among the participants.Conclusions: Enrolment in any health insurance plan would be a tool for reducing the family\u27s financial burden and accessing appropriate treatment when needed. This may be accomplished by educating communities about the need for health insurance
