“…Ni-Ti instruments have provided for safer, faster canal preparation and improved preservation of the original canal since their introduction into endodontics (13) . Instead of continuous rotation motion, a modern instrumentation technique was used, which used a single file in reciprocation motion (14) . While some research documented the reciprocating motion's superior efficiency, others demonstrated that rotary files resulted in more centralized preparations and fewer transportation (15,16) .…”

Purpose:The aim of this study was to evaluate canal transportation and centering ability ratio of 2 single Ni-Ti instruments; one shape and wave one gold using Cone Beam Computed Tomography scanning (CBCTs). Materials and Methods: Forty mesiobuccal canals of human mandibular first molars with a curvature angle that ranges from 15° to 35° were divided into 2 groups based on the type of instrument used to prepare the canal. Group I: instrumented with one shape and Group II: instrumented with Wave One Gold. Pre and post preparation, canals were scanned using CBCT scanner to evaluate the amount of canal transportation and centering ability ratio at coronal, middle, and apical parts of root canal system. Results: There was no statistical significance difference between the two tested groups (P<0.05) in canal transportation and centering ability. Conclusion: Both one shape and wave one gold systems preserving the canal's original form.

“…The canal present inside the blocks was prepared using K-Type hand files made up of NiTi (nickel-titanium) material with a 6% uniform taper across the working length. K-file is the most commonly used instrument for root canal shaping ( 12), (13) as it has got positive rake angle which results in optimum cutting efficiency. The 6% uniform taper is preferred because of its several advantages such as it allows irrigation agents to work more efficiently and also provides the cleanest possible canal post biomechanical preparation to clear the debris.…”

An earthquake has impacted the existing buildings around the area where the earthquake occurred. To maintain the safety of building occupants, it is necessary to evaluate the building's vulnerability. The most frequently used assessment methods are the Rapid Visual Screening (RVS) from FEMA and the push-over. FEMA can assess the exposure of a building quickly through visual observation but cannot provide a structural response. The push-over can explain the structural response seismic capacity and performance, collapse identification, and building strengthening strategies. However, the push-over has weaknesses; the analysis depends on modelling and structural analysis. This study aims to integrate push-over with FEMA to obtain the most appropriate assessment of buildings in earthquake vulnerability. Both assessment models have been applied to mid-rise buildings of flats after the earthquake. The building received a final score of 2.3 in the FEMA screening evaluation, indicating that it is secure. The push-over analysis shows the damage to the structure is Immediate Occupancy, which means only slight damage occurs. Overall, both methods give the same results and can be integrated to develop RVS and push-over assessments mutually when new modes of building failure are identified and as tools to assess fast, precise and accurate structural failure.

“…Microscopy and magnification: The use of dental operating microscopes and magnification devices has become a standard in modern endodontics [40]. These tools greatly enhance the visualization of the canal system, enabling the identification and treatment of complex anatomical variations, additional canals, and canal pathologies that would be challenging to manage with the naked eye [41].…”

The evolution of root canal instrumentation techniques has significantly impacted the field of endodontics, enhancing both the efficiency and outcomes of treatments. This review outlines the transition from manual to mechanical and rotary instruments, highlighting the role of nickel-titanium (NiTi) alloys and smart technologies in advancing procedural precision and reducing patient discomfort. Key historical developments and technological innovations, such as digital imaging and navigation systems, are explored for their contributions to improved clinical outcomes and patient satisfaction. Additionally, the review addresses the challenges presented by the complex anatomy of the root canal system and the advent of current instrumentation techniques. The potential of emerging trends, including artificial intelligence and advances in materials science, is discussed in the context of future endodontic practices. Despite the progress, challenges related to using advanced instrumentation methods, ethical considerations, and the cost factor of new technologies persist. The present review underscores the ongoing need for research and development to further refine root canal instrumentation techniques, ensuring that advancements in endodontic care remain patient-centered and accessible.
