Canadians' knowledge of cancer risk factors and belief in cancer myths.

Background: Many untrue statements about cancer prevention and risks are circulating. The objective of this study was to assess Canadians' awareness of known cancer risk factors and cancer myths (untruths or statements that are not completely true), and to explore how awareness may vary by sociodemographic and cognitive factors.

Methods: Cancer myths were identified by conducting scans of published, grey literature, and social media.

Salivary Levels of Interleukin-1β in Temporomandibular Disorders and Fibromyalgia.

Aims: To evaluate salivary levels of the proinflammatory cytokine interleukin-1β (IL-1β) in patients with temporomandibular disorders (TMD), fibromyalgia, or both conditions in comparison to healthy individuals.

Methods: A total of 69 females (18 to 84 years of age) were assigned to one of four groups: (A) healthy controls (n = 27); (B) TMD only (n = 18); (C) fibromyalgia only (n = 15); and (D) fibromyalgia plus TMD (n = 9). Clinical data and salivary IL-1β levels were evaluated.

Mandible-first sequence in bimaxillary orthognathic surgery: a systematic review.

The sequencing of bimaxillary orthognathic surgery remains controversial, although the traditional maxilla-first approach is performed routinely. The goal of this study was to present a systematic review of the mandible-first sequence in bimaxillary orthognathic surgery, to provide data that may assist in the decision as to which jaw should undergo osteotomy first in bimaxillary orthognathic surgery cases. A literature search was conducted for articles published in the English language, reporting the use of the altered sequence for bimaxillary orthognathic surgery (mandible-first), using the following descriptors: 'orthognathic' and 'double-jaw', 'orthognathic' and 'two-jaw', 'orthognathic' and 'mandible-first', 'orthognathic' and 'bimaxillary'.

Accuracy of perioperative mandibular positions in orthognathic surgery.

Mandibular position is an important parameter used for the diagnosis of dentofacial deformities, as well as for orthognathic surgery planning and execution. Centric relation (anterior and superior relationship of the mandibular condyles interposed by the thinnest portion of their disks against the articular eminencies), centric occlusion (when lower teeth contact upper teeth at centric relation), and maximal intercuspation (complete interdigitation of lower and upper teeth) are not often addressed as factors that influence the results of orthognathic surgery, although these relationships are critical to ensure accuracy during the surgery. The present study assessed occlusal measurements taken before and after the induction of general anaesthesia from consecutive orthognathic surgery subjects.

Sympathetic skin responses in adult humans during sequential swallowing.

Study Aims: Autonomic changes, especially those of sympathetic skin responses (SSR), during sequential water swallowing (SWS) have not been systematically investigated. This study aims to electrophysiologically examine these autonomic changes (SSR and heart rate) that occur during 50 ml sequential water swallowing from a cup.

Materials And Methods: Fifty-eight normal healthy adults were included in the study.
