Aim: This report highlights successful management of a rare case of a mandibular premolar with Oehler's Type IIIb Dens Invaginatus (DI) and peri-invagination periodontitis with guided intentional replantation (IR) without root canal treatment.
Methods: A 22-year-old female patient reported with discomfort and a sinus tract associated with tooth #21. Clinical examination and cone beam computed tomography revealed tooth #21 had an Oehler's Type IIIb DI with peri-invagination periodontitis.

Takayasu arteritis is a well-established medical entity involving inflammatory changes in large arteries. We describe a characteristic case of Takayasu arteritis, in a young woman with significant renal artery stenosis, presenting with hypertensive urgency. Unsuccessful guide wire passage due to fibrotic septae in lumen of the left renal artery necessitated an innovative interventional approach, using an IMA-guide catheter and a UB3 coronary guidewire to cross the lesions, followed by placement of a coronary drug eluting stent, with an aim to avoid restenosis.

Background: Severe vessel tortuosity may prevent a microcatheter from reaching a distal vessel. However, the Double-Wire Technique (DWT) may facilitate the procedure. The present study evaluated the feasibility and safety of guiding a 0.

The transportation and carrying behavior of underwater bubbles have been widely used for an underwater microactuator, cargo displacement assembly, and drug delivery. This study explores a method for underwater cargo transportation using sliding bubbles as a vehicle with directionally guided superhydrophobic wires. By exploitation of the adhesion between superhydrophobic surfaces and bubble interfaces, a bubble is able to transport a superhydrophobic O-ring along a superhydrophobic wire, effectively delivering the O-ring to the water surface.

Background: Although fractional flow reserve (FFR) is the contemporary standard to detect hemodynamically significant coronary stenosis, it remains underused for the need of pressure wire and hyperemic stimulus. Coronary angiography-derived FFR could break through these barriers. The aim of this study was to assess the feasibility and performance of a novel diagnostic modality deriving FFR from invasive coronary angiography (AccuFFRangio) for coronary physiological assessment.
