متن کاملAn in vitro study of the effect of spreader penetration depth on apical microleakage.
The purpose of this study was to evaluate the effect of spreader penetration depth on apical microleakage using the lateral compaction method. A total of 96 extracted maxillary central incisors were instrumented using the step-back method, and randomly divided into the following four experimental groups: A) with tug-back and spreader penetration 1 mm short of the working length; B) without tug-...
متن کاملEffect of needle insertion depth and apical diameter on irrigant extrusion in simulated immature permanent teeth.
The aim of this study was to compare the amount of irrigant extrusion in simulated immature permanent teeth when the apical diameter and needle insertion depth were varied. Thirty single-rooted maxillary incisors with straight root canals were selected. The root length was standardized to a length of 9 mm. The teeth were divided into two experimental groups according to the degree of apical enl...
متن کاملEffect of welding parameters on penetration depth in FB-TIG welding of 5083 aluminum alloy
In the present study, effect of current, welding speed and preheat temperature during FB-TIG welding of AA5083 aluminum alloy was studied. Using the Taguchi method, 9 different tests were designed to investigate the effect of welding parameters on the penetration depth. Consistent with predictions, increasing the current and preheat temperature, and reducing the welding speed led to an increase...
