root surfaces were inspected under a stereomicroscope to exclude the possibility of any external defects or cracks. Radiographs taken from the buccolingual and mesiodistal angles verified that the teeth had a similar width to that of the root canals at 9 mm from the
Evaluation of microcrack formation during root canal preparation …
Cleaning and shaping of the canals damage the root dentin, leading to dentinal cracks. Newer techniques for root canal preparation, including Ni-Ti rotary files and SAF system, have been developed for use in pediatric endodontics to overcome the drawbacks of conventional methods.
precipitate vertical root fractures. This endangers the prognosis of an endodontically treated tooth or can even lead to tooth extractions. Aim: To compare dentinal microcrack formation during biomechanical preparation by different Nickel-Titanium rotary endodontic instruments, Reciprocating single file system and
Radicular dentinal microcracks during biomechanical root canal ...
Vertical root fracture (VRF), is an appalling outcome of endodontic treatment, which often leads to tooth extraction [1]. Biomechanical preparation of root canal complex is an integral step in root canal procedure, however, research has shown it can lead to formation of craze line, fractures or incomplete cracks [2].
Dentinal Microcracks after Root Canal Preparation in Primary Root…
There is a possibility of dentinal crack formation in primary teeth after root canal preparation using rotary files. To evaluate and compare the effect of ProTaper-Gold and Kedo-S rotary files on crack formation after root canal preparation in primary molars.
Dentinal Microcrack Formation after Root Canal Instrumentation …
Microcomputed tomography (micro-CT) is the method of choice to evaluate and assess dentinal defects and microcracks induced by root canal instrumentation with different systems. It allows the investigators to evaluate hundreds of axial sections per tooth to accurately detect the exact location of a microcrack [6].
Incidence of Dentinal Microcracks during Root Canal Preparation …
Microcrack formation could be a serious side effect of mechanical root canal preparation that influences the integrity of the remaining hard tooth tissues and reduces its ability to withstand the functional and parafunctional forces.
Comparative Evaluation of Dentinal Microcrack Formation …
2021年8月1日 · This study aimed to compare root dentinal microcrack formation after root canal shaping using rotary, reciprocating, and adaptive instruments at different working lengths using micro–computed tomographic imaging.
dentinal microcracks, a clinical problem that reduces tooth resistance and facilitates vertical root fracture (VRF).3,4 VRF is one of the most frustrating complications of root canal treatment, which often results in tooth extraction.5 Root fracture might occur as a result of a microcrack that propagates with repeated stress application by occlusal
Root fractures in teeth that have undergone root canal therapy represent a highly frustrating complication, often leading to the extraction of the tooth due to its severe consequences. Given the catastrophic impact, it becomes crucial to identify the causative factors of root fractures to enhance preventive measures effectively.3
