“…The infrared scanner captured images can be influenced by external light illumination and unwanted reflection that can interfere with the device accuracy [7,14]. Thus, it is possible that this minimal errors observed in our results could be reduced with real patient computed tomography images.…”

“…Despite the usefulness of this technique, the process of occlusal plane transfer from patient to dental articulator has numerous of non-controllable errors, such as plaster contraction, that are inherent to the technique [4,5]. With the development of Computer Tomography Scans (CT), patient's 3D representations created important anatomical evidence for surgical applications, as well as for others areas of dentistry [6,7] and medicine [8]. This 3D images analysis allowed surgeons to analyze anatomical patterns of each patient in a customized way.…”

“…However, according to Patel et al, these results should be interpreted with caution since the simulated VRFs in some previous studies have been potentially wide enough to be detected clinically and/or radiographically in a clinical setting (14). In addition, ex vivo studies do not take into account subtle patient movements during CBCT scan acquisition; these movements have a negative effect on the reconstruction algorithms and cause motion artifacts that blur the image (15).…”

“…Further clinical studies are required to quantify and assess the value of CBCT in diagnosing root fractures, especially in endodontically treated teeth and with a proper control group. However, CBCT may reveal subtle signs of periradicular bone loss associated with an undetected VRF (14). For these reasons, in the current study, VRFs were artificially created to simulate in vivo conditions.…”

Effect of Time Lapse on the Diagnostic Accuracy of Cone Beam Computed Tomography for Detection of Vertical Root Fractures

Accurate and early diagnosis of vertical root fractures (VRFs) is imperative to prevent extensive bone loss and unnecessary endodontic and prosthodontic treatments. The aim of this study was to assess the effect of time lapse on the diagnostic accuracy of cone beam computed tomography (CBCT) for VRFs in endodontically treated dog's teeth. Fortyeight incisors and premolars of three adult male dogs underwent root canal therapy. The teeth were assigned to two groups: VRFs were artificially induced in the first group (n=24) while the teeth in the second group remained intact (n=24). The CBCT scans were obtained by NewTom 3G unit immediately after inducing VRFs and after one, two, three, four, eight, 12 and 16 weeks. Three oral and maxillofacial radiologists blinded to the date of radiographs assessed the presence/absence of VRFs on CBCT scans. The sensitivity, specificity and accuracy values were calculated and data were analyzed using SPSS v.16 software and ANOVA. The total accuracy of detection of VRFs immediately after surgery, one, two, three, four, eight, 12 and 16 weeks was 67.3%, 68.7%, 66.6%, 64.6%, 64.5%, 69.4%, 68.7%, 68% respectively. The effect of time lapse on detection of VRFs was not significant (p>0.05). Overall sensitivity, specificity and accuracy of CBCT for detection of VRFs were 74.3%, 62.2%, 67.2% respectively. Cone beam computed tomography is a valuable tool for detection of VRFs. Time lapse (four months) had no effect on detection of VRFs on CBCT scans.

“…CBCT extend to endodontic treatment, as shown by Tyndall and Rathore 2 and Patel et al 3 demonstrating that CBCT imaging could potentially replace 2-D intraoral imaging, especially for endodontic applications. The usefulness of CBCT for therapeutic decision-making in endodontics was indicated by Mota de Almeida et al 4 , whereby differences in endodontic treatment planning were compared before and after CBCT examination.…”

: This retrospective study used cone beam computed tomography CBCT to evaluate various radiographic prognostic indicators that affect the outcome of root canal retreatment. The study population was selected from consecutive patients examined in the endodontic department from June 1 to December 31, 2013. In total, data were collected for 143 patients mean age 47.7 years ; female : 89, male : 44 who underwent CBCT examination, including 276 roots with periapical radiographs of 158 teeth. CBCT images were re-interpreted independently by one oral radiologist for cases of periapical root resorption and periapical hypercementosis. Nonsurgical endodontic retreatment was indicated for 125 roots, and was subsequently performed by one of four certi ed endodontists. Each case was followed up and the prognosis was assessed in October 2014. Of 125 root canal-treated cases, 96 were deemed to have a satisfactory prognosis, 27 were considered questionable and 2 were considered unsatisfactory . In the 96 satisfactory cases, 15 showed periapical hypercementosis, and 51 showed periapical root resorption. The chi-squared test was used to analyze differences between groups. A value of P 0.05 was considered signi cant. There was a signi cant difference in the prognosis between the hypercementosis cases and the other groups. Several studies suggest that the presence of root resorption may worsen the prognosis of endodontic treatment. In this study, the presence of root resorption did not affect prognosis. This study provides evidence that CBCT is helpful in evaluating the prognosis of endodontic retreatment cases.
