Background: Inflammatory bowel disease, which includes ulcerative colitis (UC), is an inflammatory disorder with potential impact on periodontal disease, but evidence to date for this association is limited. The primary aim of this study was to investigate the prevalence of periodontitis according to the 2017-classification in a cohort of subjects with UC. The secondary aim was to assess a potential correlation of periodontal status with previous UC disease parameters and to assess oral health-related quality-of-life.

Orthodontic treatment as triggering factor of Medication Related Osteonecrosis of the Jaw in a breast cancer patient. Report of a rare case.

Background: Orthodontic treatment in adult patient is widely accepted nowadays. Therefore, orthodontists are needed to interact with more complex medical histories that may interfere with the orthodontic treatment. Antiresorptive medication is a widely used treatment for osteoporosis or malignancies that may affect the orthodontic movement and planning.

Expanding on the professional role of dental hygienists as key managers of medical-dental and hospital-dental clinic collaboration in a local Japanese hospital without a dentistry department: From a questionnaire survey after a web seminar.

Introduction: Perioperative oral management (POM) was introduced into the Japanese universal health insurance system in 2012. Collaboration with dental clinics is important for hospitals without a dentistry department. A dental hygienist newly assigned as a member of the patient flow management centre led a seminar to promote collaboration via the web.

Oral hygiene and infective endocarditis: a case control study.

Objective: To determine if oral hygiene is associated with infective endocarditis (IE) among those at moderate risk for IE.

Characterization of visual processing in temporomandibular disorders using functional magnetic resonance imaging.

Background And Purpose: Many patients with chronic pain report hypersensitivity not only to noxious stimuli, but also to other modalities including innocuous touch, sound, and light, possibly due to differences in the processing of these stimuli. The goal of this study was to characterize functional connectivity (FC) differences between subjects with temporomandibular disorders (TMD) and pain-free controls during a visual functional magnetic resonance imaging (fMRI) task that included an unpleasant, strobing visual stimulus. We hypothesized the TMD cohort would exhibit maladaptations in brain networks consistent with multisensory hypersensitivities observed in TMD patients.

APOBEC3B Is Co-Expressed with PKCα/NF-κB in Oral and Oropharyngeal Squamous Cell Carcinomas.

The enzymatic activity of APOBEC3B (A3B) has been implicated as a prime source of mutagenesis in head and neck squamous cell carcinoma (HNSCC). The expression of Protein Kinase C α (PKCα) and Nuclear Factor-κΒ p65 (NF-κΒ p65) has been linked to the activation of the classical and the non-canonical NF-κB signaling pathways, respectively, both of which have been shown to lead to the upregulation of A3B. Accordingly, the aim of the present study was to evaluate the expression of PKCα, NF-κΒ p65 and A3B in non-HPV related oral and oropharyngeal squamous cell carcinomas (SCC), by means of immunohistochemistry and in silico methods.

Consideration of mouth opening when using positioning stents during radiotherapy for tongue cancer: a retrospective study.
