Root fractures are relatively uncommon among other dental traumas and mostly affect the anterior dentition. This case report presents the endodontic and prosthodontic management of a maxillary central incisor with a combined fracture in the middle third of the root and the crown, as well as the 7-year follow up of the case. The healing potential of a horizontal root fracture in the middle third...

The cyclic fatigue resistance of K3 and EndoSequence files was compared by rotating files against a highly polished surface inclined at 15 degrees to the horizontal. For each brand, files with a 25 tip in .04 and .06 taper and files with a 40 tip in .04 and .06 taper were tested at both 300 and 600 rpm. A 3-mm axial movement simulated a clinical pecking motion at 1 cycle per second. The number ...

Dental trauma sometimes causes fractures in the maxillary anterior teeth leading to esthetic, functional and phonetic quandaries. In this report, we describe the treatment of middle third root fracture of maxillary centrals and cervical third crown fracture of lateral incisor simultaneously fractured due to dental trauma. Treatment involved reattachment and splinting of fractured fragments with...

A youi^g Mahomedan Sowar fell from the roof of a house at night time, and sustained a compound fracture of both radius and ulna on the left side, at about two inches above the wrist joint. When admitted into the dispensary, very soon after the accident, the lower end of the upper portion of the radius projected through a jagged horizontal wound at site of fracture. There was very little haemorr...

This study proposes to collect long term production data from wells in many different shale basins and evaluate well performance using production data analysis (PDA) with both rate and pressure data where possible, and rate transient analysis (RTA) when only rate data is available. Also, we propose to request injected fracture fluid volumes in order to quantify load recoveries and horizontal we...

The criticality of ULF (Ultra-low-frequency) magnetic variations is investigated for the 2011 March 11 Tohoku earthquake (EQ) by natural time analysis. For this attempt, some ULF parameters were considered: (1) Fh (horizontal magnetic field), (2) Fz (vertical magnetic field), and (3) Dh (inverse of horizontal magnetic field). The first two parameters refer to the ULF radiation, while the last p...

Abstract A series of true axial hydraulic fracturing experiments were conducted to understand the complex fracture initiation and propagation behavior multilayered rocks. Moreover, a new convenient grid measurement method was presented describe effectiveness. The experimental results revealed that transverse vertical non-planar fractures could be created in area scanning by match indicated trad...

Gravity drainage is one of the important recovery mechanisms in fractured carbonate and conventional reservoirs. It occurs due to density difference between the gas in fracture and the oil in matrix as well as in conventional tilted reservoirs. Oil phase will form films which are produced under gravity forces (film flow). Many gas injection experiments have been done on laboratory scales with d...

The goal of this research was to find the implant which would provide a better possibility of the fractured osteoporotic bone weight bearing after trochanteric fracture fixation. The authors constructed a new implant based on the conventional condylar plate, as part of a stabile triangular system. Because of the special oblique form of the screw which absolutely stabilizes vertical and horizont...
