An audit of pre-operative dental radiographs in patients who received no pre-operative dental input before cardiovalvular surgery.

Purpose To radiographically characterise dental disease burden and related characteristics of referred patients awaiting cardiovalvular surgery (CVS) in the context of infective endocarditis (IE) risk.Methods Radiographic evidence of dental disease levels was assessed for patients referred for dental assessment pre-CVS using available orthopantomographs (OPTs) prescribed by the cardiology team. This group did not receive any pre-CVS dental intervention or treatment.Results The majority of OPTs were Quality Standard 2 (87.5%). There was radiographic evidence of dentoalveolar disease in those patients proceeding to CVS. Periodontal disease was most prominent, with 79% of patients having advanced bone loss. The mean number of apical lesions was 0.71. Overall decayed, missing, and filled teeth score was 16.4, along with mean missing teeth scores of 7.9. None of the patients have so far developed IE at a minimum of six-month follow-up.Conclusions In our context, the quality of the radiographs requested by non-dental clinicians and delivered by non-dental-school-based radiographic departments is suboptimal and needs to be addressed. This audit should help to inform the debate around the timing and delivery of evidence-based, specialist dental care for CVS patients.

Infective endocarditis and oral surgery input before cardiac surgery: time to prick the paradigm of pre-cardiac surgery assessments?

Purpose To review current practice regarding oral surgery input for patients awaiting cardiac valvular surgery and who are at risk of infective endocarditis (IE) in the context of the COVID-19 pandemic, and to stimulate debate around the indications for pre-operative oral surgery assessment. It also opens the way to developing a new research-based approach which is patient-centred, safe, effective and efficient.Methods A desk-top based patient review was undertaken between 27 March 2020 and 1 July 2022 to record the outcome of patients undergoing cardiac valvular surgery in Northern Ireland, following the revision of the referral guidelines for oral surgery intervention. Data were collected for all cardiac referrals to the oral surgery on-call service in the Royal Victoria Hospital, Belfast. Complications were recorded at two weeks, two months, and six months post-surgery, using Northern Ireland Electronic Care Records.Results In total, 67 cardiac patients were identified between 27 March 2020 and 1 July 2022: 65.7% of patients were male and had an average age of 68, while the female patients had an average age of 61. The mean interval of date of cardiology referral to surgery date was 9.7 working days, with 36% of patients referred within five days of the planned surgery date. Moreover, 39% had valvular surgery in combination with another type of cardiac surgery. No complications linked to dental aetiology were noted.Conclusions This paper raises questions about the advisability of oral surgery input before cardiac surgery for anything other than pain relief, management of acute dental sepsis, or IE whose source has been identified as an oral commensal. The COVID-19 pandemic has presented an opportunity to review current practice and open the way to developing a new approach which is patient-centred, safe, effective and efficient.

Delivering teaching in dentistry at Queen's University, Belfast for 100 years.

Dental education has been delivered in Queen's University for just over 100 years, with the Dental School celebrating its centenary in 2020. During that time, the undergraduate curriculum has evolved greatly, through innovations in the delivery of teaching and assessment driven by changes in educational practice, developing technologies and, most recently, the COVID-19 pandemic. Throughout all of these changes, our focus remains on our students, their wellbeing, and their development as lifelong learners for a career in the dental profession.
