In vitro radiographic density of dental posts measured by digital radiography

Oral Radiology, 2013
This study evaluated the radiopacity of seven commercial root canal posts. Digital radiographs of the seven commercial posts and of the same commercial posts and four artificial aluminum posts inserted in lower canines were obtained with a CCD-based digital sensor.

Guided transpositional bone blocks in esthetic zone: Surgical technique and case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background The ultimate objective of implant dentistry is to position the implant in a three‐dimensional, prosthetic‐driven location. This case highlights a guided approach for harvesting and positioning an autogenous bone block to restore a horizontal bone defect in the anterior maxilla.

Automatic Recognition of Landmarks on Digital Dental Models [PDF]

arXiv, 2020
Fundamental to improving Dental and Orthodontic treatments is the ability to quantitatively assess and cross-compare their outcomes. Such assessments require calculating distances and angles from 3D coordinates of dental landmarks. The costly and repetitive task of hand-labelling dental models impedes studies requiring large sample size to penetrate ...

A simplified method to obtain perceptibility curves for direct dental digital radiography

Dentomaxillofacial Radiology, 1999
OBJECTIVES To derive and test a simplified method to construct Perceptibility Curves (PCs) for dental digital detectors. METHODS Mathematical expressions were derived to make it possible to construct PCs from viewer data obtained at two exposures, one low and one high. PCs were constructed applying these expressions and compared with data previously

Diagnostic yield of dental radiography and digital tomosynthesis for the identification of anatomic structures in cats

Frontiers in Veterinary Science
IntroductionDigital tomosynthesis (DT) has emerged as a potential imaging modality for evaluating anatomic structures in veterinary medicine. This study aims to validate the diagnostic yield of DT in identifying predefined anatomic structures in feline cadaver heads, comparing it with conventional intraoral dental radiography (DR).MethodsA total of 16 ...
