Root Canal Preparation Does Not Induce Dentinal Microcracks in Vivo

Journal of Endodontics, 2019
This in vivo study aimed to evaluate the development of dentinal microcracks after root canal preparation of contralateral premolars with rotary or hand instruments using micro-computed tomographic technology.Sixty contralateral intact maxillary and mandibular premolars in which extraction was indicated for orthodontic purposes were selected and ...

Preexisting Dentinal Microcracks in Nonendodontically Treated Teeth: An Ex Vivo Micro–Computed Tomographic Analysis

Journal of Endodontics, 2017
This study evaluated the prevalence, location, and pattern of preexisting dentinal microcracks in roots of extracted teeth without endodontic treatment in patients from 2 age groups using micro-computed tomographic imaging.Six hundred thirty-three nonendodontically treated teeth extracted using an atraumatic procedure because of reasons unrelated to ...

Detecting Dentinal Microcracks Using Different Preparation Techniques: An in Situ Study With Cadaver Mandibles

Journal of Endodontics, 2017
This study assessed the frequency of dentinal microcracks using a cadaver mandible model in teeth instrumented with TRUShape (TS; Dentsply Sirona, York, PA), WaveOne Gold (WO, Dentsply Sirona), or K-files (KF) compared with an uninstrumented control group (CG).Fifteen human mandibles with 95 single-rooted teeth were randomly distributed into the ...

Detection of Dentinal Microcracks Using Infrared Thermography

Journal of Endodontics, 2013
It is difficult to make a definite diagnosis of a cracked tooth solely based on an inspection within the root canal, especially in case of microcracks. At present, there seems to be no established method to detect dentinal microcracks in roots; therefore, the current detection techniques need to be improved.

The impact of long‐term storage conditions on the development of experimental dentinal microcracks

Australian Endodontic Journal, 2023
AbstractThis study evaluated the impact of long‐term storage conditions (medium and time) on the development of experimental dentinal microcracks through micro‐computed tomography. Sixty freshly extracted premolars were stored in formalin, water, or dry conditions (n = 20) and scanned after 72 h, 30 days, 6 months and 3 years of extraction.
