Crown or root fractures are the most commonly encountered emergencies in the dental clinic. Root fractures occur in fewer than eight percent of the traumatic injuries to permanent teeth. They are broadly classified as horizontal and vertical root fractures. Correct diagnosis of root fractures is essential to ensure a proper treatment plan and hence, the best possible prognosis. Indication of th...

We have administered aerosolized pentamidine (AP) to 48 AIDS patients for secondary prophylaxis of Pneumocystis carinii pneumonia (PCP). Pentamidine 60 mg was administered by ultrasonic nebulization (Fisoneb) five times during the first two weeks and then every two weeks. The mean follow-up was 343 +/- 22 days. PCP recurred in ten patients, 297 +/- 33 days after starting AP therapy. All respond...

Sucrose concentration of sugarbeets (Beta vulgaris L.) grown in the U.S. varies over a wide range of 10 to 20 percent. Within a climatic zone such as tration varies over a narrower 20 percent. This variation in southern Idaho, sucrose concenbut still wide range of 14 to sucrose concentration is due to many factors that include variety (19, 24, 26), nitrogen (N) level (18, 23), growth patterns o...

Cementoblastoma is characterized by the formation of cementum-like tissue in direct connection with the root of a tooth. It is a rare lesion constituting less than 1% of all odontogenic tumors. We report a unique case of a large cementoblastoma attached to the lateral root surface of an impacted permanent mandibular third molar in a 33 year old male patient. The association of cementoblastomas ...

Introduction 3TRV \0 A method was developed to manipulate available soil water on large trees by intercepting thrufall with gutters placed under tree canopies and irrigating the intercepted thrufall onto other trees. With this design, trees were exposed for 2 years to either 25 percent less thrufall, normal thrufall, or 25 percent additional thrufall. Undercanopy construction in these plots mod...

OBJECTIVE The aims of this study were to understand if practicing dentists appreciate the difference in criteria for success used in the endodontic and implant literature, to evaluate the perceived outcome of implant therapy compared with endodontic treatment, and to evaluate current and projected utilization of implant and endodontic treatment. STUDY DESIGN A 16-question survey was distribut...

From 1995 to 1998, more than 90 percent of mid-range IPOs were charged underwriter fees, or spreads, of exactly seven percent, even though evidence suggests that economies of scale in the size of the offering should allow for lower fees. Chen and Ritter (2000) offer collusion as a possible explanation based on empirical analysis and observation. Alternatively, we investigate whether the spreads...

Slow and unreliable infection in the greenhouse has been a barrier to research on Armillaria root disease. The existing infection assay takes 7-18 months for detectable infection, during which time the inoculum often dies, resulting in unequal challenge among plants. Because symptom expression and mortality are rare, presence or absence of infection, determined by culturing, is the only datum d...

OBJECTIVE To determine the percent gutta-percha-filled area in the apical third of root canals after filling with 2 different root filling techniques. MATERIALS AND METHODS Thirty extracted human lower premolars were instrumented with ProTaper rotary files (Dentsply Maillefer) and then randomly divided into 2 groups of 15 teeth each. The first group was filled using the single-cone technique ...

PURPOSE Composite sacropelvic resection for locally advanced recurrent rectal cancer is a high-risk procedure that benefits select patients. We reviewed our recent institutional experience to evaluate case selection, morbidity, and outcomes. METHODS Between 1987 and 2004, 29 patients underwent composite resection for recurrent locoregional rectal cancer (17 females; median age, 60 years). Cli...
