EVALUATION OF MICROCRACK FORMATION AFTER ROOT-END PREPARATION WITH TWO DIFFERENT TYPES OF ULTRASONIC RETROTIPS AND CONVENTIONAL BUR: A STEREOMICROSCOPIC STUDY

Introduction: The aim of this in vitro study is to evaluate and compare the root-end cavities for the presence of microcracks after cavity preparation using two different ultrasonic (US) retrotips read more and conventional bur.Materials and Method: Thirty single-rooted teeth were instrumented and obturated.Three millimeters of apices were resected

Target detection by means of space-based passive radar sensors generally requires the adoption of long integration time strategies to reinforce sufficiently the signal strength.These are usually based on the recovery of the target Doppler-rate to cope with the range and Doppler migration experienced over the long dwell considered.In this work, we p
