AbstractCone beam computed tomography (CBCT) provides multiplanar cross-sectional imaging and three-dimensional reconstructions and can be used intraoperatively in a hybrid operating room. In this study, we investigated the feasibility of using a CBCT-scanner for detecting residual stones during percutaneous nephrolithotomy (PCNL). Intraoperative CBCT-scans were made during PCNL procedures from November 2018 until March 2019 in a university hospital. At the point where the urologist would have otherwise ended the procedure, a CBCT-scan was made to image any residual fragments that could not be detected by either nephroscopy or conventional C-arm fluoroscopy. Residual fragments that were visualized on the CBCT-scan were attempted to be extracted additionally. To evaluate the effect of this additional extraction, each CBCT-scan was compared with a regular follow-up CT-scan that was made 4 weeks postoperatively. A total of 19 procedures were analyzed in this study. The mean duration of performing the CBCT-scan, including preparation and interpretation, was 8 min. Additional stone extraction, if applicable, had a mean duration of 11 min. The mean effective dose per CBCT-scan was 7.25 mSv. Additional extraction of residual fragments as imaged on the CBCT-scan occurred in nine procedures (47%). Of the follow-up CT-scans, 63% showed a stone-free status as compared to 47% of the intraoperative CBCT-scans. We conclude that the use of CBCT for the detection of residual stones in PCNL is meaningful, safe, and feasible.

Abstract Introduction Percutaneous nephrolithotomy (PCNL) is the standard surgical treatment method for large kidney stones. Its aim is to achieve a stone-free status, since any residual fragments (RFs) after PCNL are likely to cause additional morbidity or stone growth. Enhancing intraoperative detectability of RFs could lead to increased stone-free rates and decreased re-intervention rates. Cone beam computed tomography (CBCT) has recently been introduced in urology as a feasible method for intraoperatively imaging RFs. The aim of this trial is to determine the added value of CBCT in percutaneous nephrolithotomy, by measuring differences in stone-related morbidity for patients with procedures in which a CBCT is used versus patients with procedures without the use of CBCT. Methods The CAPTURE trial is an investigator-initiated single-center, randomized controlled trial (RCT) in adult patients who have an indication for percutaneous nephrolithotomy. A contemporary percutaneous nephrolithotomy is performed. Once the surgeon is convinced of a stone-free status by means of fluoroscopy and nephroscopy, randomization allocates patients to either the study group in whom an intraoperative CBCT scan is performed or to the control group in whom no intraoperative CBCT scan is performed. The main endpoint is the stone-free status as assessed four weeks postoperatively by low-dose non-contrast abdominal CT, as a standard follow-up procedure. Secondary endpoints include the number of PCNL procedures required and the number of stone-related events (SREs) registered. The total study population will consist of 320 patients that undergo PCNL and are eligible for randomization for an intraoperative CBCT scan. Discussion We deem a randomized controlled trial to be the most effective and reliable method to assess the efficacy of CBCT in PCNL. Though some bias may occur due to the impossibility of blinding the urologist at randomization, we estimate that the pragmatic nature of the study, standardized circumstances, and follow-up methods with pre-defined outcome measures will result in a high level of evidence.

ABSTRACT Internal resorption in the permanent dentition is a rare pathologic condition. Clinical differentiation of perforative cervical internal resorption from cervical external resorption is considered to be a challenging task. Advanced imaging techniques, such as cone beam computed tomography (CBCT) have proven vital diagnostic tools in the detection and management of these lesions. Management of a perforated internal resorption needs comprehensive endorestorative and periodontal approach. This article describes 1 year follow-up of the successfully managed perforative cervical internal resorption in permanent mandibular first molar. The affected tooth was endodontically treated, and the resorptive defect was restored with resin-modified glass ionomer cement (RMGIC) through periodontal flap surgery.

Severe atrophy of the maxillary anterior region may make implant placement difficult and as a result, iatrogenic complications such as nasal floor perforation may occur.  The purpose of this case report is to present radiographic and nasal endoscopic features in the anterior nasal floor when dental implants were inadvertently perforated into nasal cavities. Between 2003 and 2018, four patients recorded with anterior nasal floor perforation with dental implants were followed and reviewed with panoramic radiographs and cone-beam computed tomography. Also, nasal endoscopic examinations were performed by one otolaryngologist. Four implants in four patients were included in this case report. All implants achieved osseointegration and survived for 5-23 years without clinical complications. Three implants did not show any mucosal thickening and only one had minor mucosal thickening as visible on the radiographs.  Nasal endoscopy examinations revealed that three implants were covered with mucosa and one had threads exposed. Intraorally, only one had clinical signs of peri-implant mucositis. Dental implants that perforated into the anterior nasal floor did not show clinical, radiographic, and nasal endoscopic complications during the long-term follow-up period. Nasal endoscopy was a better diagnostic tool to evaluate the implants perforated into the nasal cavity than conventional panoramic or cone-beam computed tomography.

Crown Lengthening

Excessive gingival display is a common clinical presentation that often requires surgical intervention. This report is for a patient for whom esthetic crown lengthening is indicated due to altered passive eruption. Cone beam computed tomography (CBCT) scan and an intraoral scan were used to design and print a single surgical guide which provided a reference for both gingivectomy and osteoectomy. A satisfactory outcome was obtained 6 months after surgery. The present technique provided a simplified method of generating a surgical guide with predictable results by relying on the existing tooth anatomy rather than diagnostic waxing. This technique is particularly useful when crowns or veneers are not indicated.
