Does dental rehabilitation under general anaesthetic contribute to the development of temporomandibular disorders in children and adolescents? A scoping review.

BACKGROUND: Temporomandibular disorders (TMDs) have multiple aetiological factors. Although some evidence suggests invasive and lengthy dental procedures may contribute towards TMD development, there is a relative paucity in the literature regarding an association between elements of paediatric dental general anaesthesia (pDGA) and TMDs. This review aims to consider the impact of dental rehabilitation (and its constituent elements) performed under general anaesthesia on the development of TMDs in childhood and adolescence and identify theories and/or gaps in knowledge which may benefit from future research. METHODS: Due to the need to preliminarily examine the nature and extent of the current evidence base, a scoping review approach was chosen. The review was conducted based on the framework provided by the methodological working group of the Joanna Briggs Institute (JBI) for conducting systematic scoping reviews. Electronic databases MEDLINE, Embase, Scopus, Web of Science and Cochrane Library were searched as well as the grey literature using OpenGrey, Nexis, Ethos, Google Scholar and ProQuest, with eligible studies uploaded onto Zotero (Mac Version 5.0.96.2). RESULTS: A total of 810 records were identified. After removing duplicates and those not available in English, 260 were identified for title and abstract screening. Seventy-six records underwent full-text review of which only one met the broad inclusion criteria. The most common reasons for exclusion were no specific relation to general anaesthesia, not specifically relating to dental treatment and only being concerned with TMD management. The included study found that while development of TMDs following dental rehabilitation under GA did occur in children, whether the problems caused by treatment were exacerbated by other elements of the pDGA process remains unknown. CONCLUSION: This review has confirmed a distinct paucity of research in this field. While there is no current tangible scientific evidence that common and routine dental procedures lead to TMD, the literature shows that alterations to any one or a combination of critical factors can contribute to TMD development, which may be collectively exacerbated by iatrogenic macrotrauma during the pDGA process. We have highlighted elements of pre-, peri- and post-operative pDGA, alongside biopsychosocial factors, which may contribute to TMD development in childhood and adolescence and may benefit from future research.

Dental foundation training in the COVID-19 era - the national recruitment lottery.

National recruitment has radically transformed the selection and allocation of dental graduates to dental foundation training (DFT) schemes across England, Wales and Northern Ireland, with recruitment in Scotland via a separate, independent process. It has been reported as a mostly positive change to the previous deanery-led model, in which nepotism allegedly featured too widely. A candidate's ranking is typically based on performance across two face-to-face assessments and a situational judgement test (SJT). The COVID-19 pandemic, however, has created a recruitment 'lottery' of sorts, in which ranking for 2021 is now solely based on the SJT. Subject matter experts assert that neither preparation nor revision for the SJT is required; yet, following the announcement of the adaptation to DFT recruitment for September 2021, a rapid rise of exorbitantly priced SJT question banks, mock papers, workshops and courses has ensued - a shameless monetisation of the collective angst and increased pressure faced by dental students. Preparation courses present a conceivable risk of SJT 'coaching' and 'faking'. Where medicine leads, dentistry usually follows and future selection to DFT needs to strongly consider the introduction of academic performance measures. SJTs remain one of the most well-accepted, reliable and cost-effective means of selection into healthcare roles, however, only when part of a wider selection process.
