Ultrasonic Tips is considered one of the common tool used in the management of separated instruments in the root canal, . , this research aimed to evaluate the temperature rise of the outer surface of the root when using ultrasonic tips to remove separated instruments from mesiobuccal canal of the lower molars.

Aim: to compare the shaping ability of NiTi hand instruments with Stainless- steel instruments in preparation of curved root canal in extracted teeth. Materials and Methods: a total of 24 of curved root canal were randomly divided into two groups. O ne group was prepared using stainless steel instruments and the other prepared NiTi instruments. Curvatures pre-and post instrumentation were registered and compared. And straightening of the canals were determined by autocad analysis system. Results: two systems were significantly changed the original canal curvature with no differences between both systems. However, the time required to finish preparation was significantly less with NiTi system. Conclusion: under the conditions of this study, it can be concluded that two hand instrumentation system changed the original canal curvature, but the time consuming to finish the preparation was less with NiTi hand system.
Residual Calcium Hydroxide dressing on the root canal is considered one of the reasons of endodontic treatment failure. So ,the removal of this dressing completely before filling is required. The aim of the study was to evaluate the efficiencies o f passive ultrasonic irrigation And increasing the instrumentation of the medicated canal to the file one size larger than MAF in removal of Calcium Hydroxide dressing.
The specimen consists of 72 extracted teeth with curved roots (15-35)degree . They were cleaned and preserved in formalin for 48 hours. Each tooth was mounted in a self curing acrylic block. The samples were divided into three groups. Each group (24 canals) was instrumented with one of the systems (WaveOne, Reciproc, OneShape).
The ideal goal of periodontal instrumentation is to effectively remove plaque and calculus without causing root surface damage and various instruments have been designed to achieve this goal. Root planing aim to create a root surface which is biolo gically acceptable to surrounding soft tissues and increase root surface roughness. Aim of study: To evaluate the increasing of root surface roughness produced by hand curettes and piezoelectric ultrasonic instrument with different power settings .
This study was carried out to evaluate the influence of a mixture of doxycycline HCl, citric acid, and polysorbate 80 (MTAD) on the smear layer formed on root surface after hand-instrumented periodontal treatment. MTAD was compared with the influence of tetracycline HCl.
