Effect of enveloping and disinfection methods on artefact formation on enveloped PSP plate images.

Objectives: To investigate the artefacts caused by different disinfection and protection methods that can be used for infection control of photostimulable phosphor (PSP) plates.

Methods: The plates that were enveloped with single or double envelopes were sprayed with an alcohol-containing solution or wiped with an alcohol-containing tissue. Four PSP groups with two plates in each group were formed (A = wiping single envelope, B = wiping double envelopes, C = spraying onto single envelope, and D = spraying onto double envelopes).

Does the horizontal condylar angle have a relationship to temporomandibular joint osteoarthritis and condylar position? A cone-beam computed tomography study.

Background: The aim of the study was to evaluate the relationship between the horizontal condylar angle (HCA), temporomandibular joint osteoarthritis (TMJ OA), and condylar position on cone-beam computed tomography (CBCT) images.

Materials And Methods: Based on TMJ OA, joints were classified as affected and the unaffected. According to the OA condition of their joints, three groups of patients were formed: control group (n = 159, 41.

Idiopathic coronal resorption in impacted permanent teeth and its relationship with age: radiologic study.

Purpose: The purpose of this study was to evaluate the relationship between idiopathic coronal resorption and age in adult patients.

Materials And Methods: 3405 digital panoramic radiographs present in the archive of the radiology department belonging to 1584 males and 1821 females aged 25 and over were assessed by two oral and maxillofacial radiologists. The patients' age, gender, number of impacted teeth, number and position of teeth with idiopathic coronal resorption and the extent of coronal resorption were recorded on standard forms.

Reproducibility and agreement of clinical diagnosis of occlusal caries using unaided visual examination and operating microscope.

Aim: To assess the reproducibility of clinical diagnosis of occlusal caries using unaided visual examination and examination with an operating microscope (16 x magnification) and to determine the agreement between these 2 methods.

Materials And Methods: Three experienced dentists used unaided visual examination and an operating microscope to grade, according to a standard caries rating scale, a total of 299 occlusal surfaces in 112 subjects (mean age 28.3 years, standard deviation 0.
