ABSTRACT In three patients with unintentional extrusion of cold ceramic beyond the root apex, favorable clinical and radiographic outcomes were observed over 2–4 years. These descriptive observations do not establish the safety or biological effects of extruded material, but support careful clinical and radiographic follow‐up when patients remain ...

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement
ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like

Designed and Testing of the Positive Displacement Motor Driven Rotary Percussion Drilling Device
The stability and service life of common rotary percussion drilling downhole tool is influenced by poor working conditions and is far from the field requirement. In view of this,a PDM driven drill string reciprocating percussion concept has been proposed,

The Sanitization of the Night: Gentrification and the Everyday Temporal Politics in Belgrade
ABSTRACT Urban scholarship increasingly recognizes that processes such as gentrification unfold not only through spatial transformations, but through shifts in sensory environments and everyday rhythms. In this paper, drawing on twenty‐three months of fieldwork in Belgrade, I examine how urban redevelopment (re)organizes time for middle‐class people ...

A Stepwise Approach to Managing Bilateral Maxillary Sinus Tracts: A Case Report
ABSTRACT This case report describes a rare presentation of bilateral intraoral sinus tracts of odontogenic origin associated with a maxillary right first molar (Universal #3). A key diagnostic challenge was differentiating an endodontic infection from vertical root fracture (VRF) in a previously treated tooth; no J‐shaped probing defect was detected ...
