Effect of Delayed Scanning and Scanning Resolution Using Photostimulable Phosphor Plates On Detection of Vertical Root Fracture

Abstract

Abstract Objectives Detecting vertical root fractures(VRFs) can be challenging in dentistry due to their subtle and often concealed nature.This study aimed to assess the impact of varying resolutions and delayed scanning times of PSP plates on the diagnosis of VRFs. Can different resolutions and/or delayed scan times enhance the diagnosis of VRFs? Materials and Methods Forty extracted single-rooted premolar teeth were utilized. The crowns of all teeth were removed, and root canals were prepared.The teeth were divided into two groups:20 study teeth with VRFs and 20 teeth without VRFs. VRFs were created using an Instron machine. All tooth roots were positioned in the premolar region of a dry human mandible. Subsequently, periapical radiographs were taken using a parallel technique. Radiographs were scanned at four different times post-exposure:immediately, 30 minutes later, 2 hours later, and 4 hours later, and at three different resolutions:high speed, high resolution, and super high resolution.Statistical analyses were conducted using IBM SPSS Statistics 26.0. Results Intra- and interobserver agreement exhibited substantial to almost perfect ranges of agreement. Statistically significant differences were not observed in the diagnosis of VRFs when comparing different resolutions and scanning times. Conclusions Varying resolutions and/or delayed scan times did not improve the diagnosis of VRFs. In clinical practice, a comprehensive detection of VRFs might necessitate a combination of different imaging techniques, incorporation of artificial intelligence technology, and clinical assessment. Clinical Relevance: Engaging with an oral and maxillofacial radiologist or endodontist and taking into consideration their expertise and clinical judgment can prove to be advantageous for achieving precise diagnosis and effective treatment planning.
