The aim of this study was to evaluate the quantity of apically extruded debris after canal shaping with three single-file systems. ⋯ WaveOne Gold showed the best results regarding apical debris extrusion. Difference between WaveOne Gold and HyFlex EDM suggests that file design and motion kinematics affect the quantity of debris extrusion.

To assess the validity of using the calibration ruler for correcting magnification of linear measurements and to explore and compare the vertical and horizontal magnification of four digital cephalometric units. ⋯ The metal millimeter calibration ruler is an accurate reference for linear measurement magnification correction. Because of unpredictability and machine specificity, the magnification and distortion of a cephalometric unit should be calibrated for the estimation of cephalometric measurement error.

Prenatal distress and fear of childbirth negatively affect the health of the mother and the fetus. Sociodemographic and pregnancy related characteristics may influence prenatal distress and fear of childbirth. ⋯ The results of this study revealed that fear of childbirth and prenatal distress were moderately and positively correlated. NUPDQ and W-DEQ can be used during pregnancy to understand if pregnant women have fear or distress. This could help to give a better support to pregnant women.

Isometric handgrip exercise training attenuates blood pressure in prehypertensive subjects at 30% maximum voluntary contraction.
Prehypertension highlights a category of subjects who are at high risk of developing hypertension. ⋯ This study has shown that isometric handgrip exercise is effective in the attenuation of blood pressure in prehypertensive subjects especially when combined with the routinely recommended lifestyle modifications. However, caution should be taken when recommending it because of acute increase in blood pressure.
