An in vitro comparative study of working length changes in curved canals after coronal flaring by using rotary and hand instrumentation


Abstract in English

The aim of this study is to investigate the effect of early coronal flaring on changing the working length of curved canals by using NiTi rotary instruments and SS manual instruments. Forty five MB curved canals of upper/lower first and second extracted molars were used.
