Oral appliances (OAs) represent a widespread treatment modality for patients with mild to moderate obstructive sleep apnea (OSA). OAs exist in many designs, but it is unknown if there are differences in terms of side effects between the various types. The aim of this pilot study was therefore to evaluate two OA designs, one rigid type of appliance (OAR) and a more flexible one (OAF) regarding i...

Meteorological observing networks are nearly always irregularly distributed in space. This irregularity generally has an adverse impact on objective analysis and must be accounted for when designing an analysis scheme. Unfortunately, there has been no completely satisfactory measure of the degree of irregularity, which is of particular significance when designing artificial sampling networks fo...

The purpose of this study involving a sample of children with single central incisor crossbite was to determine the relationship between clinical crown lengths of the crossbite and noncrossbite mandibular incisors, incisor irregularity, and orthodontic correction of the crossbite. In addition, for comparison, the normal maturational change in position of the labial gingival margin of mandibular...

PURPOSE To determine which US signs are important in the diagnosis of a surgically identifiable supraspinatus tendon tear. MATERIALS AND METHODS Fifty consecutive ultrasonographic (US) studies of the shoulder in patients who underwent arthroscopic follow-up were retrospectively reviewed by a musculoskeletal radiologist. US images of the supraspinatus tendon were evaluated for tendon nonvisual...

To study the seeding mechanism of ionospheric irregularity occurrences, a correlation study has been carried out between the global monthly/latitudinal (m/l) distributions of irregularity occurrences and the deep atmospheric convective clouds in the intertropical convergence zone (ITCZ) indicated by the outgoing longwave radiation (OLR) measurements. Seven longitude sectors the African, Indian,...

This study investigated the early effects on mandibular incisor irregularity and rotation together with dental arch dimensions of the extraction of four deciduous canines. Children, during early mixed dentition, were randomized into one extraction (n = 32) and one control (n = 41) group. Dental casts from baseline (T0) and 1 year follow-up (T1) were used to evaluate changes in the irregularity ...
