BACKGROUND There have been no quantitative standards for volumetric and surface measurements of the mandibular condyle in Caucasian population. However, the recently developed cone-beam computed tomography (CBCT) system allows measurement of these parameters with high accuracy. METHODS CBCT was used to measure the condylar volume, surface and the volume(More)
AIM The aim of this study is to assess if, and to what extent, myotonic dystrophy can affect the craniofacial growth pattern. MATERIALS AND METHODS The research was conducted on a sample of 27 patients with Steinert's myotonic dystrophy (study group). Each subject underwent a clinical examination with impression-taking and intra- and extraoral(More)
AIM The authors evaluated radiation and skin doses absorbed by the eye lens, as well as the parotid and thyroid glands, during a low dose maxillary spiral computed tomography (CT). METHODS Three spiral CTs were carried out, one after the other, changing from time to time MAS, pitch factor, Kv and consequently, CTDI/Vol, until the minimum values detectable(More)
BACKGROUND During orthodontic treatment, a low resistance to slide (RS) is desirable when sliding mechanics are used. Many studies showed that several variables affect the RS at the bracket-wire interface; among these, the design of the bracket slot has not been deeply investigated yet. This study aimed to clarify the effect of different slot designs on the(More)
BACKGROUND The aim of this study was to evaluate the amount of radiation doses absorbed by soft tissues (entrance skin dose) with a low-dose spiral computed tomography (CT) protocol compared to conventional X-ray techniques commonly used in orthodontics. METHODS The amount of skin dose has been evaluated using a tissue-equivalent head-neck radiotherapy(More)
Dysphagia is defined as difficulty in swallowing food (semi-solid or solid), liquid, or both. Difficulty in swallowing affects approximately 7% of population, with risk incidence increasing with age. There are many disorder conditions predisposing to dysphagia such as mechanical strokes or esophageal diseases even if neurological diseases represent the(More)
OBJECTIVE To investigate the resistance to sliding (RS) in self-ligating and conventional ligation bracket systems at 5 different second-order bracket angulations by using low-stiffness alignment wires in a 3-bracket experimental model and to verify the performance of the main RS components in both systems when these wires are used. METHODS Interactive(More)
OBJECTIVES This in vitro study evaluated the friction (F) generated by aligned stainless steel (SS) conventional brackets, self-ligating Damon MX(©) brackets (SDS Ormco, Glendora, California, USA), Time3(©) brackets (American Orthodontics, Sheboygan, Wisconsin, USA), Vision LP(©) brackets (American Orthodontics), and low-friction Slide(©) ligatures (Leone,(More)
