OBJECTIVE This study aimed to evaluate the accuracy and precision of polyurethane (PUT) dental arch models fabricated using a three-dimensional (3D) subtractive rapid prototyping (RP) method with an intraoral scanning technique by comparing linear measurements obtained from PUT models and conventional plaster models. METHODS Ten plaster models were duplicated using a selected standard master ...

INTRODUCTION The objective of this study was to evaluate the accuracy and reliability of measurements on digital models obtained by scanning impressions 5, 10, and 15 days after they were made from 2 soft putty polyvinylsiloxane (PVS) materials. METHODS Thirty volunteers were selected for making impressions of their dentitions with alginate to create a plaster model and with PVS impression ma...

Five percent lidocaine medicated plaster has been proven efficacious for the symptomatic relief of neuropathic pain in diverse pain conditions which might be attributed to a common localized symptomatology in these indications, possibly with common predictors of treatment success. To discuss potential symptoms and other factors predicting response to treatment with lidocaine plaster for the ind...

Forensic dentistry can significantly contribute to the identification of victims especially in cases of charred, decomposing, mutilated or skeletonized bodies. However, in order to make this procedure technically feasible it is necessary to find dental records produced before death. This study aims to report a case of a mummified body identified through dental traits found within a plaster cast...

BACKGROUND Post-herpetic neuralgia (PHN) is the most common and most debilitating complication of herpes zoster, and involves considerable associated costs. OBJECTIVE This paper presents results from nine health economic studies undertaken in eight European countries that compared lidocaine medicated plaster with gabapentin and/or pregabalin in PHN. It aims to support the increasing need for ...

INTRODUCTION The aim of the research was to answer the question: can 3D virtual models replace plaster models and can they improve the orthodontic treatment process and the organization of work in the orthodontic practice. MATERIAL AND METHODS The comparison analysis included diagnostic plaster and 3D virtual models of 25 patients who met the following criteria: (1) malocclusion; (2) no prior...

OBJECTIVE The aim of this study was to compare the accuracy of Bolton analysis obtained from digital models scanned with the Ortho Insight three-dimensional (3D) laser scanner system to those obtained from cone-beam computed tomography (CBCT) images and traditional plaster models. METHODS CBCT scans and plaster models were obtained from 50 patients. Plaster models were scanned using the Ortho...

When peripheral neuropathic pain affects a specific, clearly demarcated area of the body, it may be described as localized neuropathic pain (LNP). Examples include postherpetic neuralgia and painful diabetic neuropathy, as well as post-surgical and post-traumatic pain. These conditions may respond to topical treatment, i.e., pharmaceutical agents acting locally on the peripheral nervous system,...

Post-herpetic neuralgia (PHN) is neuropathic pain persisting after an acute episode of herpes zoster, and is associated with severe pain and sensory abnormalities that adversely affect the patient's quality of life and increase health care costs. Up to 83% of patients with PHN describe localized neuropathic pain, defined as "a type of neuropathic pain characterized by consistent and circumscrib...

A five-year-old boy presented with a simple undisplaced fracture of the lower end of the left radius. An above-elbow plasterwas applied and he was sent home. Twenty-four hours later a “ plaster check” revealed a swollen hand and the patient complained of intense pain. There was a rash on the left anterior abdominal wall and he was mildly febrile (38.3 degrees Celsius). The plaster was removed a...
