Diagnostic Accuracy of Three Cone Beam Computed Tomography Systems and Periapical Radiography for Detection of Fenestration Around Dental Implants.

Context: Early detection of peri-implant bone defects is highly important to prevent further bone loss and implant failure.

Aims: This study aimed to assess the diagnostic accuracy of three cone-beam computed tomography (CBCT) systems and periapical radiography for detection of fenestration around dental implants.

Methods: Thirty-one titanium implants were placed in the bovine ribs, in which peri-implant fenestration were simulated.

Efficacy of denoising and enhancement filters for detection of approximal and occlusal caries on digital intraoral radiographs.

Background And Objectives: Image processing and enhancement filters can significantly improve the diagnostic value of digital radiographs. Evidence shows that increasing the contrast and filtering improve the diagnostic accuracy for caries detection. This study sought to assess the diagnostic accuracy of original and enhanced digital radiographs for the detection of approximal and occlusal caries.

Comparing the effects of mineral trioxide aggregate and calcium enriched mixture on neuronal cells using an electrophysiological approach.

Introduction: The main goal of this ex vivo study was to assess and compare the cellular and electrophysiological effects of two dental biomaterials, white mineral trioxide aggregate (WMTA) and calcium enriched mixture (CEM) cement, on neuronal cell excitability and electrical properties.

Materials And Methods: A conventional intracellular current clamp technique was used to study the cellular effects of WMTA and CEM on the excitability, firing and the shape of action potential of neuronal soma membrane of F(1) nerve cells. The dental biomaterials were prepared according to the manufacturers' directions and were applied to the bathing media and 0.
