Evaluation of Radiopacity of Calcium Silicate-Based and Resin-Based Materials Using Direct Digital Radiography Along With an Aluminium Step Wedge.

Background Radiopacity is a critical property for root canal sealers as it allows for the assessment of the material's placement and quality within the root canal system on radiographic images. The study aimed to evaluate the radiopacity of calcium silicate-based and resin-based materials using direct digital radiography, employing an aluminium step wedge according to American National Standards Institute/International Organization for Standardization (ANSI/ISO) standard protocols for testing the radiopacity of root canal sealers. This study seeks to determine the effectiveness of these materials in meeting the required standards for clinical use.

Comparative Analysis of the Efficacy of Various Retreatment File Systems in the Removal of Gutta-Percha in Retreatment Cases and Time Taken During the Procedure: An In Vitro Cone Beam CT Study.

Background Removing gutta-percha manually can be a challenging task, especially when addressing densely packed root-filling material, particularly in cases where resin-based sealers are employed for obturation. The use of nickel-titanium (NiTi) rotary instruments not only effectively shapes the root canal but also efficiently removes the endodontic filling from the curved canal during retreatment. Hence, incorporating rotary NiTi instruments in retreatment cases can alleviate fatigue for both patients and operators.

Comparison of the Microleakages of Four Root-End Filling Materials: An In Vitro Study.

Introduction: When a nonsurgical endodontic treatment is ineffective, surgery is necessary. This entails putting a retrofilling to seal the tooth's apex. Exposing the lesion, performing a curettage, exposing the root apex, resecting it, preparing the root end, and lastly filling the cavity with the proper material are all steps in endodontic surgery.

Analysis and forecasting of road traffic mortalities in Azad Jammu and Kashmir.

Objective: To analyse road traffic accident mortalities in a geographical region.

Method: The retrospective study was conducted in Azad Jammu and Kashmir based on secondary data from 2004 to 2017 collected from the police department. Duncan's multiple range test was used to assess the trends in road traffic accident fatalities with respect to districts and divisions.

Healthcare professionals' perspectives on lung cancer screening in the UK: a qualitative study.

Background: Lung cancer screening with low-dose CT has been shown to decrease mortality. Low lung cancer survival rates in the UK, driven primarily by late-stage presentation, provide the impetus for implementing screening. Nascent guidance on screening in the UK recommends primary care case-finding.

Healthcare professionals' perspectives on lung cancer screening in the UK: a qualitative study.

Background: Lung cancer screening with low-dose computed tomography (LDCT) has been shown to decrease mortality. Low lung cancer survival rates in the UK, driven primarily by late-stage presentation, provide the impetus for implementing screening. Nascent guidance on screening in the UK recommends primary care case-finding.

Biological activities of Allium sativum and Zingiber officinale extracts on clinically important bacterial pathogens, their phytochemical and FT-IR spectroscopic analysis.

The spread of bacterial infectious diseases is a major public threat. Herbs and spices have offered an excellent, important and useful source of antimicrobial agents against many pathological infections. In the current study, the antimicrobial potency of fresh, naturally and commercial dried Allium sativum and Zingiber officinale extracts had been investigated against seven local clinical bacterial isolates such as Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia, Staphylococcus aureus, Streptococcus pyogenes, Staphylococcus epidermidis, and Serratia marcesnces by the agar disc diffusion method.

Statistical study of the risk factors of myocardial infarction in the patients of district Muzaffarabad capital of Azad Jammu and Kashmir.

Coronary artery disease (CAD) is a leading cause of mortality in the developing countries. The aim of the study was to check the association of Myocardial infarction (MI) with several factors such as smoking & smoking exposure, blood pressure, sugar & cholesterol level, stress, anxiety & lifestyle. A cross sectional community based survey was conducted involving 469 patients having one or more risk factors or having complains regarding MI & already diagnosed MI, was taken using Multistage sampling technique from Sheikh Zaid Hospital & Abbas Institute of Medical Sciences.

Women's reproductive autonomy and barriers to contraceptive use in Pakistan.

Objective: To determine through the log-linear model analysis technique the impact of women's reproductive autonomy, spouses' educational background and other factors on the use of contraception in Pakistan.

Methods: Data from the Pakistan Reproductive Health and Family Planning Survey 2000 were used. In this survey a national sample of married women aged 15-49 years (n = 6579) were interviewed.
