The purpose of this study was to determine whether a near‐infrared diode laser could be used as an adjunct to help identify and localise symptomatic cracks in patients with cracked tooth. An 810‐nm diode laser at 1 W continuous wave energy with a 200 micro‐fibre tip was used to scan the offending tooth. Crack identified during the laser scan was removed, restored and reviewed after four weeks and after 4 years. The laser was able to significantly (P = 0.0001) identify suspected cracked teeth from non‐cracked control teeth. Of the twelve patients examined, ten participants experienced discomfort as the laser passed over a crack line. At 4‐week and 4‐year recall, a majority of the ten treated patients responded positively to the management of crack. This study showed that diode laser could be an adjunctive tool for early detection and management of symptomatic cracks with the possibility of improving long‐term survival. 相似文献

A 64-year-old male had an awake right nasal fiber-optic intubation with an endotracheal tube for open reduction and internal fixation of bilateral displaced mandibular fractures. After induction of anesthesia, an 18 Fr nasogastric tube (NGT) was inserted through the left nostril and was secured. The patient required high flow rates to deliver adequate tidal volumes with the ventilator. A chest x-ray done in the postanesthesia care unit revealed a malpositioned NGT in the left lower lobe bronchus, which was immediately removed. The patient was extubated on postoperative day 2. Various traditional methods, such as aspiration of gastric contents, auscultation of gastric insufflations, and chest x-ray are in use to detect or prevent the misplacement of an NGT. These methods can be unreliable or impractical. Use of capnography to detect an improperly placed NGT should be considered in the operating room as a simple, cost-effective method with high sensitivity to prevent possibly serious sequelae of an NGT placed within the bronchial tree.Key words: Nasogastric tube, Misplacement, Oral surgeryPlacement of a nasogastric tube (NGT) preoperatively for decompression of the stomach is common practice to allow drainage of gastrointestinal contents in the case of bowel obstruction, or in other cases when the patient is at risk of aspiration for some other reason. This case report involves a patient who required aspiration precautions via NGT placement for mandibular surgery due to facial trauma; the NGT was later found to be misplaced in the left main stem bronchus as the misplacement was unrecognized intraoperatively. We discuss the necessity of preventing the possible intraoperative and postoperative complications of a misplaced NGT and simple measures to recognize misplacement in patients presenting for similar surgeries. 相似文献

Prosthetic Rehabilitation Following Socket Reconstruction with Blair‐Brown Graft and Conformer Therapy for Management of Severe Post‐Enucleation Socket Syndrome – A Clinical Report 下载免费PDF全文
Himanshi Aggarwal MDS Saumyendra V. Singh MDS Pradeep Kumar MDS Arun Kumar Singh M.Ch. 《Journal of prosthodontics》2015,24(4):329-333
One of the most common tumors of the eye diagnosed in childhood is retinoblastoma, which mandates enucleation with adjunctive chemotherapy and radiotherapy to save the patient's life. The most common late enucleation complication is post‐enucleation socket syndrome (PESS), which poses a management dilemma for the prosthodontist and surgeon, along with being a major esthetic concern for the patient. The reconstruction of such sockets is complex. The purpose of this clinical report is to describe the rehabilitation of such a pediatric patient with severe PESS. The patient was successfully rehabilitated by presurgical conformer therapy, socket reconstruction surgery with non‐meshed intermediate split thickness skin graft (STSG)/Blair‐Brown graft, and postsurgical conformer stent. This was followed by fabrication of a custom ocular prosthesis, to achieve favorable functional, physical, and psychological effects. 相似文献

We present a rare case of reentrant ventricular tachycardia proven by entrainment maneuvers that was successfully ablated from the noncoronary cusp. The case highlights regional anatomy, pacing maneuvers with multi‐modality images from fluoroscopy, intracardiac echo, and electroanatomical mapping. 相似文献
