Objectives: Dentists manage a variety of oral infections in clinical practice. Inappropriate antimicrobial prescribing by dentists occurs frequently and antimicrobial stewardship strategies should include dentistry. The aim of this retrospective analysis of the Australian Hospital National Antimicrobial Prescribing Survey (Hospital NAPS) dataset, was to describe the types of oral and dental indications where antimicrobials were prescribed, and assess the guideline compliance and appropriateness of the antimicrobials in Australian hospitals.

Objectives: Dentistry is a significant contributor to the burden of antimicrobial overprescribing and hence to the global problem of antimicrobial resistance. However, antimicrobial stewardship in Canadian dentistry is nascent, with an acknowledged need for research and coordinated stewardship efforts. This study aimed to gain insights into the perspectives of Canadian dentistry sector leaders and experts on the main drivers of dental antibiotic overprescribing and potential stewardship strategies.

Background Patients presenting with dental pain are common in general practice, despite dental infections being most appropriately managed with dental treatment to address the cause of the infection. Although antibiotics are not appropriate for the management of localised toothache without signs of systemic spread, general practitioners (GPs) often prescribe antibiotics and analgesics for the management of dental pain. The aim of this study was to explore GPs' perceptions and management of dental presentations in Australia.

This narrative review describes the oral microbiome, and its role in oral health and disease, before considering the impact of commonly used over-the-counter (OTC) mouthwashes on oral bacteria, viruses, bacteriophages, and fungi that make up these microbial communities in different niches of the mouth. Whilst certain mouthwashes have proven antimicrobial actions and clinical effectiveness supported by robust evidence, this review reports more recent metagenomics evidence, suggesting that mouthwashes such as chlorhexidine may cause "dysbiosis," whereby certain species of bacteria are killed, leaving others, sometimes unwanted, to predominate. There is little known about the effects of mouthwashes on fungi and viruses in the context of the oral microbiome (virome) in vivo, despite evidence that they "kill" certain viral pathogens ex vivo.

Article Synopsis
  • Oral mucosal conditions are prevalent and can significantly affect quality of life, leading researchers to assess how well Australian pharmacists and final-year pharmacy students recognize and manage these issues.
  • An online questionnaire featuring six case scenarios was completed by 65 pharmacists and 78 students, revealing that while most participants had encountered various oral mucosal conditions, many lacked knowledge of best practice recommendations for managing them.
  • The findings highlight the need for enhanced training programs focused on oral healthcare for pharmacists in Australia to improve their ability to provide effective treatment for oral mucosal diseases.

Aims: Medication-related osteonecrosis of the jaw (MRONJ) is an uncommon but potentially debilitating condition, characterised by nonhealing jawbone, with or without mucosal exposure, in the presence of certain drugs. Those already strongly associated with MRONJ include antiresorptives denosumab and bisphosphonates; however, a growing range of other non-antiresorptive drugs is implicated. The aim of this study was to analyse all case reports of MRONJ submitted to the publicly available Database of Adverse Event Notification from the Therapeutic Goods Administration in Australia.
