Halitosis in oral lichen planus patients.

To investigate the halitosis level in oral lichen planus (OLP) patients and OLP-free participants. This cross-sectional study recruited 70 participants at the New Zealand's National Centre for Dentistry. Halitosis was determined using the objective measurements (parts per billion (ppb) volatile sulphur compounds (VSCs) in the exhaled air) and subjective measurement (self-reported halitosis questionnaire).

Construction of the chronic temporomandibular disorder patients: the association between neural and psychological pathways.

Chronic temporomandibular disorder (cTMD) as a term based on the diagnostic criteria for temporomandibular disorders (DC/TMD) classification refers, in this paper, to the condition listed that has a non-mechanical association without any obvious organic cause. Specifically, this is the condition that falls under the International Classification of Diseases 11th revision (ICD-11) classification of chronic primary and chronic secondary pains. This implies that there is increased responsiveness of nociceptive neurons in the central nervous system, a phenomenon known as central sensitisation.

In many countries, teledentistry programs were established although not much is known about the extent of incorporating teledentistry into practice and healthcare systems. This study aimed to report on policies and strategies related to teledentistry practice as well as barriers and facilitators for this implementation in 19 countries.

Effect of the Rho-Kinase/ROCK Signaling Pathway on Cytoskeleton Components.

The mechanical properties of cells are important in tissue homeostasis and enable cell growth, division, migration and the epithelial-mesenchymal transition. Mechanical properties are determined to a large extent by the cytoskeleton. The cytoskeleton is a complex and dynamic network composed of microfilaments, intermediate filaments and microtubules.

Review of taste and taste disturbance in COVID-19 patients.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is responsible for the coronavirus disease 2019 (COVID-19) pandemic that has become a significant global public health concern. The virus gains entry to cells via angiotensin-converting enzyme-2 (ACE2) receptors, which have been found to be the functional receptor for SARS-CoV-2 infection. High expression of ACE2 is found in type II alveolar cells, macrophages, bronchial and tracheal epithelial cells and in the oral cavity, particularly on the tongue.

Pathological mechanism of chondrocytes and the surrounding environment during osteoarthritis of temporomandibular joint.

Temporomandibular joint (TMJ) osteoarthritis is a common chronic degenerative disease of the TMJ. In order to explore its aetiology and pathological mechanism, many animal models and cell models have been constructed to simulate the pathological process of TMJ osteoarthritis. The main pathological features of TMJ osteoarthritis include chondrocyte death, extracellular matrix (ECM) degradation and subchondral bone remodelling.

Naringenin promotes SDF-1/CXCR4 signaling pathway in BMSCs osteogenic differentiation.

Introduction: Naringenin, a dihydro-flavonoid compound that shows chemotactic activity, may have a good application prospect in repairing bone tissue, but its specific mechanism in bone regeneration, especially the osteogenic differentiation of stem cells, needs for a further study. The aim of this study was to investigate the effect of naringenin on the osteogenic differentiation and its roles in the C-X-C chemokine receptor type 4/stromal cell-derived factor 1 (SDF-1/CXCR4) signal pathway of bone marrow-derived mesenchymal stem cells (BMSCs).

Material And Methods: BMSCs were harvested from the femurs and tibias of 4-to-6-week-old male Sprague-Dawley rats.

Quantitative and qualitative analyses of orthodontic-related videos on YouTube.

Objectives: To investigate content of orthodontic-related videos on YouTube to improve the understanding of orthodontic patients' perceptions and treatment experiences.

Oral health knowledge and practice among orthodontic clients in China and New Zealand.

Background: The oral hygiene habits of clients wearing fixed orthodontic appliances is poorly understood. Assessment of oral hygiene behavioural patterns is essential for understanding clients' oral health care needs. The aim of this study was to investigate orthodontic clients' oral hygiene behaviours, brushing techniques, and oral hygiene awareness.

Use of traditional medicine for dental care by different ethnic groups in New Zealand.

Background: There is an increasing public interest in the use of TM internationally, yet there is a paucity of research on the use of TM by the public in the dental setting. This study aimed to explore the views, use of and access to TM in dentistry among different ethnic groups residing in New Zealand.

Methods: Qualitative study and in-depth interviews were used.

Can the Measurement of Jaw-Opening Forces Assist in the Diagnosis of Temporomandibular Disorders?

Aims: To investigate the effectiveness of a novel jaw-opening-force measuring device as a screening tool to aid in the diagnosis of temporomandibular disorders (TMD).

Methods: Symptomatic TMD patients (n = 58) and control TMD-free participants (n = 56) were screened by an oral medicine specialist according to the Diagnostic Criteria for TMD (DC/TMD).

Management of oral medicine emergencies during COVID-19: A study to develop practise guidelines.

Coronavirus disease (COVID-19) pandemic has become a significant global public health concern. Since the announcement of the Public Health Emergency of International Concern, many countries have implemented lockdown and restrictive quarantines; therefore, routine dentistry, as well as oral medicine practise, have been suspended in several countries. However, urgent oral cares and emergencies are still operated and delivered by on-call dental practitioners.
