Safe Siders is an Endodontic Instrumentation System that is non-circular, non-interrupted flat sided instruments in a sequence designed to simplify the endodontic process.

It follows canal paths while cutting efficiently. SafeSiders Glide Path Kits can be used by hand or in the Endo-Express reciprocating handpiece to easily establish the glide path before instrumentation.

These flat-sided instruments are designed to easily navigate even the most curved or calcified canals. Password Forgot password. Don't have an account? Log In. About Darby. Subtotal: 0.

Number and percentage of dentinal defects. Only the difference between A and B was statistically significant. In the present study, Neolix single-file rotary system showed significantly higher dentinal micro cracks compared to the control group.

Since micro cracks were seen in all groups except for the control group , none of the systems could prevent micro cracks. According to a study by De-Deus et al. Shemesh et al. However, in our study, the control group did not show any micro cracks; therefore, we may conclude that the observed micro cracks were the result of the instrumentation. Previous studies reported that single-file systems are four times faster than the conventional rotary systems for instrumentation [ 18 , 23 ].

Higher number of micro cracks observed in the Neolix group may be the result of the sudden stress that is initially applied to dentinal walls. The mesial root of mandibular first molar has narrow canals. Introduction of 25 Neolix rotary file with 0. No previous study has been conducted regarding Neolix system according to our literature search.

The results of our study were in agreement with those of Priya et al. It may be the result of more stress concentration leading to micro crack formation.

There are also studies reporting that single-file systems can cause less dentinal damage than multi-file systems and it can be due to more manipulations in the canal that leads to more stress concentration [ 25 , 26 ]. Different methodologies can be a reason for this disagreement. Initial use of hand files 20 or 25 can provide more space for the rotary single-file instrument.

Recently, a 20 single-file was added to Neolix system that can decrease the risk of crack formation when used before The risk of micro crack formation by use of the ProTaper system has been evaluated in several studies. Some others, including the current study Also, a micro-computed tomography CT study done by De-Deus et al. According to burklein et al. In another study done by Liu et al.

Differences in apical size and taper could cause the conflicting results [ 33 ]. According to Kim et al. In the present study, the cross-sectional design varied from non-homothetic rectangular in Neolix group, to flat-sided D-shaped in SafeSider system and convex triangular cross-section in ProTaper group. Triangular or modified triangular design of ProTaper cross-section decreases the cutting efficiency and provides less space for dentine chips, thus generating stresses on root canal walls [ 18 ].

Our study showed that micro cracks mostly formed in the coronal third. According to Versluis et al. This could be the result of increased taper of the instrument toward the coronal dentinal walls. In the present study, only one complete fracture in samples of ProTaper group was seen. It seems that it may not be purely the result of instrumentation and some other factors probably play a role in this respect.

According to Wilcox et al. In the present study, there was no significant difference between SafeSider reciprocating hybrid system, NiTi and stainless-steel and ProTaper rotary NiTi system group.

However, micro cracks occurred in both groups, but with a higher rate in SafeSider system. In the study by Ceyhanli et al. The difference between our results and theirs may be due to different methodologies. Ceyhanli et al. The D-shaped and flat-sided design of SafeSider instruments have improved their elasticity [ 37 ].

According to the manufacturer, SafeSider files have 16 flutes compared to 24 flutes for files in ProTaper and Neolix groups.

It causes less binding with canal walls and decreases fatigue resistance, file fracture or micro crack formation, according to manufacturer [ 17 ]. Reciprocating movement has advantages such as more centered position of the instrument in root canal [ 38 ]. This movement provides continuous release of the instrument, while engaging the inner surface of the canal wall by repeating the clockwise and counter-clockwise rotation [ 39 ].

Blades of the instrument lose contact with dentinal wall during clockwise motion [ 40 ]. Furthermore, flexural and torsional forces on dentinal walls may decrease and reduce the screwing effect of the instrument and cause a reduction in dentinal crack formation [ 41 , 42 ]. Burklein and Schafer [ 28 ] reported that reciprocating movement may increase torsional forces by pushing debris toward the root apex.

Some studies reported more dentinal defects in rotational movement than reciprocal motion [ 25 ], while some others support the opposite idea [ 28 ]. Also, kinematics had no significant effect on crack formation [ 43 ]. Different methodologies can be the reason for this disagreement [ 25 , 28 ].

According to our study, various canal shapes may be achieved after preparation with different systems. Unlike Neolix that seems to create more symmetric and regular canal cross-sections, SafeSider system seems to make irregular and asymmetric shapes. Yoldas et al. Craze lines are defects not relevant directly to the pulp space or root canal wall. In the current study, only 2 craze lines were found and they were in Neolix group.

Yet, it is not fully known that this may be the result of stress production during canal preparation exceeding the tensile strength of the collagen matrix [ 33 ]. In the present study, acrylic blocks and silicon impression material were used to simulate periodontal ligament as a major stress absorber; this was done based on a previous study and can affect the results Despite most in vitro studies that used single-rooted teeth 18 , 21 - 26 for determining the risk of micro crack formation, the current study used both mesial canals of mandibular first molars for instrumentation.

This sample selection may also increase the rate of micro cracks. One of the limitations of the current study was difference in dentin thickness of teeth although we used only mandibular first molars.

Also, we could not detect pre-existing defects by our methodology sectioning and observation under stereomicroscope. Micro-CT has a higher resolution and may be more accurate for detection of dentinal defects in comparison with a stereomicroscope. However, according to Ceyhanli et al. Micro-CT makes hundreds of slices, which are not easy to assess and also some micro cracks may be overlooked. Neolix rotary single-file system caused more dentinal cracks compared to unprepared roots.

Except for the control group, all the instrumentation systems increased the number of micro cracks.
