Aim of Study: The objective of this study was to compare the shaping ability of ProTaper Rotary instruments (Universal, Next), Hand ProTaper instruments and traditional hand instruments in long oval-shaped root canals. Methods and materials: Forty human teeth with long oval-shaped root canals were sectioned at 3 levels in the coronal, middle and apical third. A modified Bramante technique was used and analyzed changes in root canal maximum buccolingual and mesiodistal canal dimensions (ΔBL ,ΔMD) and changes in surface area (ΔA) , under (10X) magnification. Where the sample was divided into four groups each one contains (N=10) teeth and prepares by one of the four instrumentation systems. The morphological changes were analyzed by software Program (Auto Cad 2013).

Research summary
تهدف هذه الدراسة إلى مقارنة فعالية أربعة أنظمة لتحضير الأقنية الجذرية ذات الشكل البيضوي الطويل، وهي: ProTaper Next (PTN)، ProTaper Hand (PTH)، Hand NiTi K-file (Tpre)، والنظام اليدوي التقليدي. تم استخدام 40 سنًا بشريًا مقلوعًا، وقُسمت الأسنان إلى أربع مجموعات، كل مجموعة تحتوي على 10 أسنان. تم تحضير الأسنان باستخدام الأنظمة الأربعة المدروسة، وتم تحليل التغيرات في الأبعاد والمساحة باستخدام برنامج AutoCAD 2013. أظهرت النتائج وجود فروق معنوية في التغيرات في القطر الدهليزي اللساني والأنسي وحشي والمساحة في الثلث التاجي، بينما لم تكن هناك فروق معنوية في الثلثين المتوسط والذروي. خلصت الدراسة إلى أن الأنظمة اليدوية (Tpre وPTH) كانت الأفضل في إحداث التغيرات في الأبعاد والمساحة في الثلث التاجي، ولكن لم يكن هناك أي نظام قادر على تحضير كامل جدران القناة الجذرية بشكل كافٍ.
Critical review
تعتبر هذه الدراسة مهمة في مجال تحضير الأقنية الجذرية، حيث تقدم مقارنة شاملة بين أنظمة التحضير المختلفة. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل استخدام عينة أكبر من الأسنان للحصول على نتائج أكثر دقة وشمولية. ثانيًا، لم يتم التطرق إلى تأثير هذه الأنظمة على مدة العلاج أو راحة المريض، وهو جانب مهم يجب مراعاته. ثالثًا، كان من الممكن استخدام تقنيات تصوير أكثر حداثة مثل التصوير المقطعي المحوسب للحصول على قياسات أكثر دقة. وأخيرًا، كان من المفيد تضمين تحليل للتكلفة والفائدة لكل نظام من الأنظمة المدروسة لتقديم توصيات أكثر شمولية للأطباء.

Aim of Study : The objective of this study was to compare the shaping ability of ProTaper Rotary instruments(Universal,Next) ,Hand ProTaper instruments and traditional hand instruments in long oval-shaped root canals. Methods and materials: Forty human teeth with long oval-shaped root canals were sectioned at one level in the apical third far 3 mm at the apical root . A modified Bramantetechnique was used and analyzed changes in root canal in surface area (ΔA), under (10) magnification. Where the sample was divided into four subgroups each one contains (N=10) teeth and prepares by one of the four instrumentation systems. The morphological changes were analyzed by software Program (Auto Cad 2013).
Aim: to compare the shaping ability of two rotary systems (Protaper Universal and Protaper Next) and K-file hand instruments in curved root canals of extracted human molars. Materials and methods:Thirty extracted molars with curved canals were cho sen. The curvature of root canals was determined (15-40o) then the sample was randomly divided into three groups: n1=n2=n3=10. Group(1): was prepared using K-file hand instruments (Stand), group(2): prepared by Protaper Universal (PTU), whereas group3: prepared by Protaper Next (PTN).The curvature after preparation and Time preparationwere evaluated. Data were collected and statistical analysis was conducted. Results: The three instrument systems (PTU, PTN, Stand) have caused significant change in original canal curvature(P<0.05). On the other hand, there were no significant differences between systemsin straightening of canal curvature (P>0.05). However, both systems: PTN, Stand were significantly faster than PTU during preparation of curved canals (P<0,001).Conclusion: under the conditions of this study, it can be concluded thatall instruments caused changing in original canal curvature. However, the new generation PTN was faster than old one PTU.
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.
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.
Aim: to compare NiTi hand instruments with Stainless- steel instruments according to separation, deformation and changing of working length during preparation of curved root canal in extracted teeth. Materials and Methods: 24 of curved root canal we re randomly divided into two groups. One group was prepared using stainless steel instruments and the other prepared by NiTi instruments. Separation and deformation of the two hand instrument systems were determined and the changing of working length during preparation were registered and compared. Data were collected and stastical analysis were conducted. Results: Stainless steel system showed more separated and deformed instruments, but there were no significant differences between two systems. Also, change of working length was happened with stainless steel only but without significant differences with NiTi. Conclusion: under the conditions of this study, it can be concluded that two hand instrumentation systems separated and deformed with no differences . However, working length was changed during use stainless steel but without differences between two system.
