PLACEMENT OF PREFORMED METAL CROWNS ON CARIOUS PRIMARY MOLARS BY DENTAL HYGIENE/THERAPY VOCATIONAL TRAINEES IN SCOTLAND: A SERVICE EVALUATION ASSESSING PATIENT AND PARENT SATISFACTION.

Abstract

The utility and acceptability of preformed metal crowns (PMC) for management of carious primary molars has been established in the literature and published guidance. The role of dental hygienist and therapists (DHT) in the evolving team model in primary care has been recognised as requiring further investigation. The importance of patient and parental acceptance is acknowledged in recent healthcare research. This study focuses on patient and parent acceptance of preformed metal crowns placed by DHTs. Prescription format is investigated and the availability of bitewing radiographs considered. Reflective assignments at the end of training gave an indication of DHTs views on increased professional autonomy and the issue of direct access. Patient and parent satisfaction following placement of PMCs by DHT vocational trainees (DHTVT) were evaluated. Data was collected in two audit rounds from 2013 to 2014 using a 'faces' scale for children and a Likert scale for parents following placement of PMCs on carious primary molars. 133 PMCs were placed (110 children) by 10 DHTVTs over an eight-month period. Overall, radiographs were available for 10.5% of cases. The data showed high levels of patient and parent acceptance of the use of PMCs. Low availability of radiographs may represent a missed diagnostic opportunity. PMC placement by DHTVTs resulted in high patient and parent satisfaction, comparable to other studies. Although caries has been declining over the last decade in Scotland, evidence shows that inequalities and a social gradient in experience of caries in children remain. There is a need for tools and strategies for the prevention, recognition, risk assessment, diagnosis, and management of caries in the primary dentition. These must be accessible, acceptable to children and their parents/carers, cost effective, affordable and applicable in the primary care general dental practice environment where most families are likely to be registered. The emerging theme of dentistry being provided in a team model with dental care professionals (DCPs) taking on an expanded role is under continuing review following the General Dental Council (GDC) announcements on 'direct access'. The Scottish Dental Hygiene and Therapy Vocational Training (DHTVT) programme is a one-year, elective, post-qualification training programme for Dental Hygiene and Therapy graduates run by NHS Education for Scotland (NES). In 2013-2014, DHTVTs were employed across six Scottish health board areas in hospital, salaried and independent settings in urban and rural locations. The elements of the programme involve a blend of clinical mentoring, web-based learning, case presentations, critical reading, reflective assignments and face-to-face theoretical and practical teaching across a number of modules. The aim of this project was to collect data to indicate patient and parental response following the placement of PMCs, collect data on the use of radiographs in children having PMCs placed and to investigate the role of dental therapists in the dental team. The data, once collated, was presented to DHTVTs to inform reflection on the management of carious primary molars and to raise awareness of issues relating to cost effectiveness of providing treatment in a primary care environment and critically appraise perceived barriers to the use of PMCs in the treatment of carious primary molars. Collated data has been presented to trainers in future cohorts to inform discussion amongst the group of trainers at induction days around dental team working, effective detection, diagnosis, risk assessment and prescription to DHTs.
