The perceptions of dental practitioners of their role as clinical teachers in a UK outreach dental clinic

A retrospective clinical study on the survival of posterior composite restorations in a primary care dental outreach setting over 11years

OBJECTIVES

To investigate the survival in terms of time to re-intervention of composite restorations in posterior teeth among patients attending for treatment at a primary care dental outreach setting over an 11-year period and to determine whether dental, patient or operator factors influenced this.

METHODS

Electronic primary dental care data were collected on individual patients, including information on their dental treatment and socio-demographics as well as service provision, key performance indicators and student activity.

RESULTS

A total of 1086 patients had at least one posterior composite placed between 2007 and 2018. This amounted to 3194 restorations placed of which 308 had a re-intervention within the 11-year period. For all restorations, the annual failure rate at 1 year was 5.73 %, at 5 years was 16.78 % and at 10 years was 18.74 %. A logistic regression showed that when compared to the least deprived 5^th quintile, the most deprived 1^st and 2^nd quintiles were significantly less likely to have a re-intervention, being 49.2 % (p = 0.022) and 53.2 % (p = 0.031) less likely, respectively.

CONCLUSIONS

The survival rates of posterior composite restorations placed at a single outreach centre providing undergraduate dental training in the South of England, mirrors other studies. The new findings presented suggest similar re-intervention rates between dental students and dental hygiene-therapy students. This study's findings around patient deprivation and rate and time of re-intervention raises important questions related to the need for targeted dental and after care for certain groups in the population.

CLINICAL SIGNIFICANCE

Understanding the factors associated with re-intervention of restorations provided to patients has an impact on patients and dental practices. Also, as we consider widening use of skill mix in dentistry to increase access to care, parity in provision of treatments within the dental team increases opportunities for delegation of tasks.

Experiential learning without prior vicarious learning: an insight from the primary dental care setting

The vicarious learning method (by observation) is used to help learners emulate their teachers' behaviours. The experiential learning method (by experience) is traditionally used thereafter, so that learners can apply these behaviours to a given situation. Both methods are widely utilised within clinical skills training. A clinical teacher may well face the question of whether a learner can complete a certain clinical task without having seen it performed before. Therefore, clinical teachers will need to determine which method, vicarious or experiential, is most effective for their learners. To help explore this, the author reflects on two examples from dental teaching practice, followed by discussion of the need to also observe soft skills; provide meaningful feedback; be a good role model; facilitate deep learning; know our learners, and implement learner-centred learning. Collectively, this reveals that although experiential learning may be possible and beneficial by itself, further research is required to fully support this.
