Rasch model is a useful method for developing a new scale. This study aims to determine the fitting between data obtained from answers for a portfolio anxiety scale and Rasch model and describes how the scale can be modified to increase the fitting through different steps. ⋯ The validity and reliability of Rasch analysis portfolio scale were analyzed, and items that worked well were included in the study. The results show that Rasch model provides a more accurate analysis for developing and adapting scales. Both the fit statistics and fit graphs help improve the analyses.

The aim of this study was to evaluate the efficacy of using erbium, chromium-doped:yttrium scandium gallium garnet (Er,Cr:YSGG) laser-treated dentine in a dentine barrier test device. ⋯ Er,Cr:YSGG laser treatment was not successful enough in decreasing the cytotoxic effects of the dental materials. Different parameters of Er,Cr:YSGG laser or different laser types could be investigated as an alternative to minimizing the cytotoxic effects of dental materials.

There has been no comprehensive study on identifying the sociocultural characteristics and the factors affecting the number of relatives and/or friends accompanying patients. The purpose of this study was to identify these sociocultural characteristics and the factors affecting this. ⋯ The number of people accompanying patients increases with sociocultural factors such as gender, age, literacy, and education level. In addition, similar increase can be observed with patients coming to emergency department by ambulance or having a chronic disease or arrive with lost consciousness.

: Intestinal helminthiasis is a major public health problem in Africa. Helminthic infection in pregnant women causes loss of appetite, poor nutrient absorption, gastrointestinal impairment, iron deficiency, and iron deficiency anemia resulting in low birth weights and preterm births. The main aim of this study is to assess the prevalence of helminthic infections in pregnant women in rural and peri-urban communities of Ibadan. ⋯ These communities are classified as Category III, having a low prevalence and low intensity infection. Therefore, prophylactic anti-helminthic treatment in pregnancy is not recommended. The inverse relationship with education may be a function of better living conditions. Better hygiene should be advocated.

The objective of this study is to compare the effectiveness of final irrigation with chitosan, ethylenediaminetetraacetic acid (EDTA), and citric acid (CA) on a resin-based sealer (AH plus sealer [Dentsply DeTrey, Konstanz, Germany]) penetration into dentinal tubules using confocal laser scanning microscopy. ⋯ Chitosan, EDTA, and CA significantly improved the percentage of SP for coronal thirds.
