INTRODUCTION The present clinical trial aimed to evaluate the efficiency of paracetamol alone and in combination with 3 different nonsteroidal anti-inflammatory drugs for control of post-endodontic pain. METHODS The inclusion criteria were moderate to severe pain of irreversible pulpitis, by using the Verbal Rating Scale and a 4-10 score on the Numerical Rating Scale, on anterior or premolar ...

This study compared faculty perceptions and expectations of dental students' abilities using virtual reality simulation (VRS) to those who did not use virtual reality simulation (non-VRS) in an operative dentistry preclinical course. A sixteen-item survey with a ten-point rating scale and three open-ended questions asked about students' abilities in ergonomics, confidence level, performance, pr...

Real time GPS measurements are becoming an essential part of surveying. During the last years several real time methods have been introduced. One of the most sophisticated one, Virtual reference station (VRS) is using GPS network to mitigate errors inherent to GPS positioning. The quality of VRS was studied in such conditions that are typical in Finland and northern latitudes. The study was div...

The present study cross-validated self-report pain scales: Verbal Rating Scale (VRS), Facial Expression Scale (FACES), Color Analogue Scale (CAS) and Poker Chip Tool (PCT) in Thai children aged 5-12 years. The concordance with observational measure, Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) was also tested. Among 100 students, test-retest reliability of all self-report measures...

Vital registration systems (VRS) are important in the collection of routine data on indicators of development. These are particularly useful if they are properly built to address weaknesses in the system leading to poor data quality. For instance, routine data on health events (e.g. morbidity, mortality etc.) are crucial for rapid assessment of disease burden and mortality trends in the populat...

The use of virtual reality simulation (VRS) is a new teaching modality in dentistry, and there is scope for further research evaluating its use under different educational programs. The purpose of this study was to evaluate how VRS with or without instructor feedback influenced students' learning and skills related to porcelain fused to metal (PFM) crown preparation. In this study, forty-three ...

Background: Chronic pain is a major public health problem and 30% to 45% of sufferers experience severe depression. Acupuncture is often used to treat both depression and a range of pain disorders. We aim to conduct a systematic review of randomized controlled trials (RCTs) to evaluate the efficacy of acupuncture for patients experiencing chronic pain with depression. Methods: To identify relev...
