520 _aThe loads required to fracture teeth prepared using rotary nickel - titanium instruments with three different tapers were determined and Compared of these fracture loads when applied on teeth having various coronal lengths under cyclic mode of loading . Forty five premolars were collected . Five premolars were kept intact , the crowns of forty premolars were sectioned to have either 2 mm " Class 1 " or 4mm " class 2 " clinical crown length
