The identification and quantification of tire and road wear particles in Osaka Bay, Japan, by two analytical methods.

Tire and road wear particles (TRWP) are generated at the frictional interface between tires and the road surface. This mixture of tire tread and road pavement materials can migrate from roads into nearby water bodies during precipitation events. The absence of mass-based measurements in marine environments introduces uncertainty in environmental risk assessments and fate and transport models.

Bridging the gap - Establishing a dental-oncology service in a cancer centre.

Dental disease remains the most common non-communicable disease worldwide. It predisposes patients to significant morbidities following bone modifying agents or radiation therapy to the head and neck. Preventative dental regimes effectively reduce the risk of both medication-related osteonecrosis of the jaw (MRONJ) and osteoradionecrosis (ORN) in these patients.

World Workshop on Oral Medicine VIII: Development of a core outcome set for oral lichen planus: the patient perspective.

Objective: This study aimed to explore the lived experience of patients with oral lichen planus (OLP) and investigate what treatment-related outcomes are the most important to them and should be included in a core outcome set (COS) for OLP.

Study Design: A qualitative study involving focus group work with 10 participants was conducted. Interviews with each focus group were held twice: session 1 explored the lived experience of patients with OLP, and session 2 allowed patients to review a summary of the outcome domains used in the OLP literature to date.

Broken needle: a rare complication of inferior alveolar nerve block - a report of two cases.

Introduction Needle fracture during the delivery of local anaesthesia is a rare complication in modern dentistry. While there has been a decline in its occurrence with the advent of disposable flexible alloys, it still occurs and it is important for all clinicians to know how to deal with this complication. The management of a lost needle in the pterygomandibular space when giving an inferior alveolar nerve block has proven a dilemma in the past.
