Near-IR reflectance spectroscopy has been used to study the curing of ethyl cyanoacrylate adhesive on polished dental glass and microscope slide substrates. The effects of changing the glue film thickness and the type of substrate on the curing rate have been investigated whilst maintaining a constant humidity. The FTIR spectral data has been used to calculate and plot the extents of cure versu...

In this study, dose area product measurements have been performed to propose diagnostic reference levels (DRLs) in intraoral dental radiology. Measurements were carried out at 60 X-ray units for all types of intraoral examinations performed in clinical routine. The third quartile values calculated range from 26.2 to 87.0 mGy cm(2). The results showed that there exists a large difference between...

It is difficult to take intraoral radiographs in some patients who are intolerable to place the film in their mouth. For these patients, Newman and Friedman recommended a new technique of extraoral film placement. Here we report various cases that diagnostic imaging was performed in patients using the extraoral periapical technique. This technique was used to obtain the radiographs for the pati...

The microbiologic contamination can occur in all the steps of an intraoral conventional or digital radiographic examination, unless some measures to avoid the cross-infection are applied. Scientific articles have shown that during the radiograph taking procedure, there is contact with the patient’s oral fluids (saliva and blood) and, consequently, the contamination of the film or digital sensor...

A basic study was made to examine what extent of radiographic changes pertaining to early periodontal disease. The standardized radiography was used to assure geometrically identical radiographs. Artificial bone defects were produced by stages at the proximal bone crest using humane dry mandible. And as to when changes occurring in the bone on dental film can be recognized, visual assessment wa...

abstract introduction. recently, the ariadent zinc phosphate cement has been introduced to market with low cost. some dentists purchase this product because of low cost and others avoid buying it because of unreliable quality. the two important properties of ideal dental cement are to have the minimum film thickness (less than 25 micron) and to have favorable compressive strength. the purpose o...
