Fiber-reinforced composite resin bridges: an alternative method to treat root-fractured teeth

The replacement of missing teeth, especially in the anterior region, is an essential part of dental practice. Fiber-reinforced composite resin bridges are a conservative alternative to conventional fixed dental prostheses or implants. It is a minimally invasive, reversible technique that can be completed in a single visit. The two cases presented herein exemplify the treatment of root-fractured anterior teeth with a natural pontic immediately after extraction.

Debris removal efficiency depend on different ultrasonic irrigation protocols

Purpose@#The purpose of this study is comparing the efficiency of debris removal of passive ultrasonic irrigation depend on different protocols. @*Materials and Methods@#Forty-eight mandibular premolars were randomly divided into 2 groups depend on vibration power (Weak and Strong, n = 24). And then two groups were subdivided into 3 groups depend on the number of times that PUI used (1, 2 and 3, n = 8). After standardization, teeth were split into two halves. On the wall of one half of root canal, three depressions were cut at 1, 3 and 5 mm from the apex and in the same way two depressions were cut on the other half of root canal at 2, 4 mm from the apex. Each depression was filled with mixture of dentine and NaOCl. After irrigation, images of the root canal wall were taken, and then the amount of remaining dentine debris was evaluated. @*Results@#There was no significant difference between weak and strong power of vibration groups. Weak vibration groups did not show significant difference depend on the different number of times PUI used. But in the strong vibration groups, twice and three times used groups show better removal efficiency. @*Conclusion@#The removal efficiency of dentine debris is not significantly different depend on the power of vibration. And multiple use of PUI could have better irrigating effects at the apical third area in the strong vibration group.

Surgical Fitness for Trochanteric Fracture in Elderly: Prospective Study

PURPOSE: The purpose of this study was to evaluate the risks of undergoing intramedullary nailing with minimum surgical optimization (fast-track) for geriatric trochanter fracture due to fall from a standing height. MATERIALS AND METHODS: From May 2006 to August 2013, 48 fractures were enrolled in fast-track, and were an average age of patients was 77.6 years (range, 62-97 years). They underwent primary testing for anesthesia, including basic body fluid test, arterial blood, electrocardiography, and chest radiographs. The time from visit to surgery was 28.9 hours (range, 1-96 hours). RESULTS: During hospitalization, there was one case of stress-induced cardiac arrest; however, other complications, infection, and 30-day mortality did not occur. According to preoperative classic test, the average albumin was 3.45 g/dl, blood sugar, 169 mg/dl, blood urea nitrogen, 20.5 mg/dl, Cr, 1.5 mg/dl, Na, 135.3 mEq/L, and K, 4.21 mEq/L. The average PaCO2 of arterial blood was 37.6 mmHg. CONCLUSION: We found that the fast-track for trochanteric fracture due to slip-down was relatively safe, and could be considered as a therapeutic approach.

A Case of Tramadol Induced Asthma Attack in a Patient with Samter's Triad / 대한이비인후과학회지

Samter's triad is a well known syndrome and is characterized by a triad of asthma, aspirin or NSAID sensitivity and chronic sinusitis with nasal polyp. Chronic sinusitis with Samter's triad is difficult to treat completely and has poor prognosis. Tramadol is a non-opioid analgesic that rarely shows respiratory suppression and is known to be relatively safe because it does not inhibit prostaglandin synthesis. For that reason, patients with asthma may avoid drug-induced exacerbations of the disease by substituting Tramadol for NSAIDs. We experienced a case of asthma attack in a patient with Samter's triad after Tramadol injection.
