PURPOSE Statistical studies conducted in various languages on both infants and adults have revealed an intersyllabic preference for initiating words with a labial consonant-vowel-coronal consonant sequence. Speech motor constraints have been proposed to explain this so-called labial-coronal effect. This study was designed to test for a possible perceptual correlate of the labial-coronal effect ...

The aim of this study was to assess the prevalence and risk factors of apical periodontitis in endodontically treated teeth in a selected population of Brazilian adults. A total of 1,372 periapical radiographs of endodontically treated teeth were analyzed based on the quality of root filling, status of coronal restoration and presence of posts associated with apical periodontitis (AP). Data wer...

OBJECTIVE To evaluate the increased value of using coronal reformation of a transverse computed tomography (CT) scan for detecting adnexal torsion. MATERIALS AND METHODS This study included 106 woman suspected of having adnexal torsion who underwent CT with coronal reformations and subsequent surgical exploration. Two readers independently recorded the CT findings, such as the thickening of a...

I propose that solar coronal heating is a self-regulating process that keeps the coronal plasma roughly marginally collisionless. The self-regulating mechanism is based on the interplay of two effects. First, plasma density controls coronal energy release via the transition between the slow collisional Sweet– Parker regime and the fast collisionless reconnection regime. This transition takes pl...

introduction: this in vitro study aims to evaluate the coronal and apical sealing ability of gutta-percha (gp) root filling used with either mineral trioxide aggregate (mta), new endodontic cement (nec) or ah26 as filler/sealers. materials and methods: forty eight single-rooted extracted teeth were selected, decoronated and then instrumented. samples were randomly divided into three experimenta...

introduction: the purpose of this study was to evaluate the sealing ability of gray-colored mineral trioxide aggregate (gmta), white-colored mta (wmta), and resilon as root filling materials. materials and methods: sixty-six human maxillary central incisors were used in the present study. in the group a, 20 teeth were filled with gmta. in the group b, 20 teeth were filled with wmta and in the g...

Introdouction: It is important for the clinician to be aware regarding the necessary thickness of materials used as intra-orifice coronal barriers to prevent microleakage. The purpose of this in vitro study was to compare coronal microleakage of three different thicknesses of white and gray Angelus mineral trioxide aggregate (WAMTA, GAMTA). Materials and methods: A total of 66 canals of extrac...

BACKGROUND Linear headache (LH) has recently been described as a paroxysmal or continuous head pain restricted in a linear trajectory of 5-10 mm in width, linking one endpoint in occipital or occipitocervical region with another endpoint in ipsilateral nasion or forehead region. The sagittal line-shaped pain area of LH is close and parallel to a sagittal venous sinus, the superior sagittal sinu...
