Gender pay differences and inequalities among UK General Dental Practitioners

Gender pay differences and inequalities among UK General Dental Practitioners

Wimpole Timings study.

Introduction Studies show that changes to dental incentive structures and treatment timings impact behaviour among UK general dental practitioners (GDP). Since 1980, the British Dental Association (BDA) has conducted panel inquiries to understand the time taken to complete dental treatments, the most recent of these being the 1999 Heathrow Timings study.Aims Given significant changes to the UK general dental service (GDS) since 1999, this research aims to gain a refreshed understanding of the time involved to complete clinical treatments in the UK and gain insight into working hours.Materials and methods This study adopted a mixed-method research design, adapted from the BDA's Heathrow Timings study. Averages for 34 adult and 12 children's treatments were found using an online survey and group discussion with 15 GDPs.Results Overall, GDPs worked 35.23 hours per week, at an hourly rate of £39.94. Comparison to the Heathrow study in 1999 shows an increase in time to deliver multiple treatments, including clinical examinations, root canals, extractions, composite fillings, porcelain veneers, acrylic full dentures and children's extractions.Conclusion Overall, this study provides a current and updated insight into dental treatment times performed by GDPs in the UK and highlights a decrease in working hours and real-term earnings of GDPs over the past 20 years.

Exploring deep caries management and barriers to the use of vital pulp treatments by primary care dental practitioners.

The European Society of Endodontology outlines best practices for the management of deep caries and the pulp. Despite evidence supporting vital pulp treatments (VPTs) as predictable alternatives to conventional endodontic treatment, studies have shown they are not widely adopted in the UK. This study aimed to explore the barriers to implementation of VPTs by primary care general dental practitioners (GDPs). Qualitative one-to-one semi-structured online interviews were conducted with purposively sampled UK GDPs. Interview transcripts were analysed using reflexive thematic analysis. Recurring themes were iteratively refined as additional transcripts were reviewed. Eleven participants were interviewed. A range of barriers to the provision of VPTs were identified, which aligned with two core themes: 'Motivational barriers to service provision' and 'Educational access & opportunities'. Sub-themes included lack of access to materials and equipment, deficiencies in knowledge of treatment (including protocols, outcomes and prognosis), lack of confidence (in treatment efficacy and clinical ability), time constraints and public dental service funding and remuneration. This study identifies barriers to the widespread adoption of VPTs among primary care GDPs in public and private settings. Economic constraints, practitioner confidence, time limitations and educational gaps are key challenges. Addressing these may require systemic changes such as policy interventions, education and improved resource allocation.

Supportive periodontal care in dental practice: Part 2 - perceptions of locally referring UK general dental practitioners.

Background Supportive periodontal care (SPC) is important in maintaining periodontal treatment outcomes. Hospital services provide specialist periodontal care at high costs. On completion of treatment, patients are discharged back to the general dental practitioner (GDP) to provide SPC. This project aimed to evaluate the change in GDPs' understanding of SPC over more than 20 years.Method A validated questionnaire about SPC was sent to GDPs during 1996 (397) and 2020 (300), with a response rate of 74% and 52%, respectively. The anonymous data were entered on a Microsoft Excel spreadsheet for analysis.Results In total, 98.5% of the GDPs in 1996 and 97% in 2020 perceived SPC to be highly important. Additionally, 49% in 2020 had a better understanding of SPC when compared to 1996 (42%). Finally, 70-74% (1996, 2020) of the GDPs indicated that they were responsible for SPC; however, 13-16% said that they were not.Conclusion and clinical relevance Notwithstanding the lower response rate in 2020, there has been an improvement in understanding and awareness of responsibility of SPC among GDPs. Reported challenges of provision were related to education and funding. If GDPs are to effectively deliver SPC, education and current funding should be addressed to prevent compromised treatment outcomes for patients.

Opinions of UK General Dental Practitioners on the Restoration of Posterior Root Filled Teeth: a Vignette Survey.

To investigate factors which influence UK general dental practitioners (GDPs) when restoring posterior root filled teeth. An electronic survey was designed to explore current strategies of treatment of posterior root filled teeth by UK-based GDPs working in primary care. Three vignette cases included in the questionnaire explored a variety of tooth, patient, and financial factors. The survey was distributed by email and social media platforms between December 2018 and February 2019. A total of 528 valid responses were collected. The majority of participants (84.1%) regularly restored posterior root filled teeth with an indirect restoration. Presence of persistent symptoms post root canal treatment (RCT) completion would impact the management of 85% of the surveyed respondents. Referral to a specialist, deferral of provision of the definitive restoration, and fear of litigation were reported by the GDPs as influencing factors. This survey highlights that decision making regarding restoration of root filled teeth is a multifactorial process. Tooth, patient, and financial factors were all shown to influence the restorative management of the posterior root filled teeth.

An internet-mediated investigation into the reported clinical use of rubber dam isolation by GDPs in the UK - part 2: clinical applications.

Aims To investigate the reported clinical applications of rubber dam isolation by UK general dental practitioners (GDPs) using an internet-mediated approach.Methods The data were collected in 2019, using an online (SurveyMonkey) questionnaire that was distributed to GDPs in a private group on Facebook. The percentages are based on the number of respondents who answered each question.Results The response rate was 61% with 403 valid completed questionnaires. The majority (395; 98%) of respondents reported using rubber dam in clinical practice. Undergraduate training in rubber dam use was received by 382 (98%) respondents, with greater training reported by younger, more recently qualified graduates. The main clinical applications of rubber dam included its use for composite restorations, endodontic treatments and internal bleaching procedures, while for other clinical procedures, the majority of respondents did not use rubber dam. For posterior and anterior composites, 332 (82%) and 298 (74%) respondents, respectively, reported using rubber dam isolation at least rarely. At least 98% (395) of the respondents used rubber dam for endodontic procedures, irrespective of tooth type and position. Over 70% (281) of respondents reported using rubber dam at least rarely for internal bleaching. Rubber dam was used by 99% (392) and 67% (262) of respondents on adults and paediatric patients, respectively.Conclusions The main clinical applications agree with previous reports, but highlight an increase in rubber dam use. This study investigated a wider range of clinical applications compared to previous studies, adding to the literature surrounding rubber dam use.

An internet-mediated investigation into the reported clinical use of rubber dam isolation by GDPs in the UK - part 1: factors influencing rubber dam use.

Aims To investigate the reported use of rubber dam isolation by UK general dental practitioners (GDPs), utilising an internet-mediated (SurveyMonkey) questionnaire reporting the demographic profile of respondents and the attitudes and factors influencing rubber dam use.Methods A piloted questionnaire was distributed to a random sample of GDPs in a private Facebook group, investigating respondent demographics, clinical applications, and attitudes towards and factors influencing rubber dam use. The data were analysed using descriptive statistics along with chi-squared and pairwise Mann-Whitney U tests.Results The response rate was 61%, with 403 valid completed questionnaires. Of these, 218 (54%) were female and 185 (46%) were male, with an age range of 23-72 years. Most of them (248; 62%) worked in mixed practices. The majority agreed that rubber dam aids placement of posterior restorations (311; 78%), provides clearer access (308; 76%), enables a higher clinical standard (355; 89%) and increases restoration longevity (257; 65%). Most agreed that proper isolation for root canal/operative procedures cannot be achieved without rubber dam use (329; 82%). Respondents disagreed with the following statements: root canal therapy completed without rubber dam isolation is as successful as those completed using rubber dam (338; 85%), rubber dam is difficult to apply (292; 73%) and rubber dam is disliked by patients (257; 64%). Respondents agreed that rubber dam use is influenced by clinical setting (259; 64%), procedure (390; 97%), choice of material being placed (382; 95%) and ease of application (337; 84%). Furthermore, 218 (54%) of the respondents expressed an interest in further training in rubber dam use.Conclusions This study provides greater insight into the attitudes and factors influencing rubber dam use, while demonstrating an interest in further training.

Current trends in endodontic irrigation amongst general dental practitioners and dental schools within the United Kingdom and Ireland: a cross-sectional survey.

Aims To investigate current trends in endodontic irrigation amongst general dental practitioners (GDPs) and dental schools within UK and Ireland. Secondly, to evaluate if significant differences exist between the irrigant practices of National Health Service (NHS) and private GDPs.Methodology In 2019, an online questionnaire was distributed to the 18 dental schools within the UK and Ireland and 8,568 GDPs. These surveys explored current trends in teaching and usage of endodontic irrigants. Chi-squared tests were performed to make comparisons between NHS and private GDPs (α <0.01).Results All 18 dental schools (100%) and 495 GDPs (6%) returned valid questionnaires. Three hundred and thirty (66.7%) practitioners were NHS and 165 (33.3%) were private. There was strong consensus on irrigation teaching amongst dental schools. These results aligned with GDP responses in terms of irrigant selection (sodium hypochlorite [NaOCl]); NaOCl concentration (≤3%); ethylenediaminetetraacetic acid (EDTA) contact time (>0-5 minutes); final rinse protocols (penultimate EDTA rinse); irrigant temperature (room); and agitation techniques (manual dynamic activation; >0-60 seconds). There was, however, considerable variation in NaOCl contact time and GDPs infrequently used chelating agents or agitation techniques. Compared with private practitioners, NHS GDPs used significantly lower NaOCl contact times and concentrations, less EDTA and activation techniques, and more chlorhexidine (P <0.01).Conclusions Overall, irrigation teaching within the UK and Ireland is consistent and evidence-based. Furthermore, trends in irrigant usage amongst UK GDPs are now more aligned with these teaching practices. Significant differences were, however, observed between NHS and private practitioners.

Management of compromised first permanent molars in children: Cross-Sectional analysis of attitudes of UK general dental practitioners and specialists in paediatric dentistry.

It is unclear on how children with compromised first permanent molars (cFPMs) are currently managed in the UK by either general dental practitioners (GDP) or specialists in paediatric dentistry (SPD). Explore the current attitudes to the management of compromised first permanent molars amongst UK general dental practitioners and specialists in paediatric dentistry. Self-completed online questionnaire including three clinical vignettes of 7, 9, and 15years old with cFPM. All registered SPDs (n=236), as of May 2017, 500 randomly selected GDPs from England, selected from a national performers list, and 52 Scottish GDPs, part of Scottish dental practice research network, were invited to complete the questionnaire. About 71.6% (n=53) of SPDs agreed that children with cFPM should be referred to a paediatric specialist for treatment planning, whereas the reverse for GDPs is true, as 86.8% (n=138) believe they have a responsibility to treat these teeth. Responses to clinical vignettes suggest a slight preference amongst GDPs to restore cFPM, including root canal treatment, whereas SPDs have a slight preference towards extraction. Current pathways for cFPM, amongst UK general dental practitioners and specialists in paediatric dentistry, vary greatly between and within each professional group.

An analysis of stress and burnout in UK general dental practitioners: subdimensions and causes.

Dentistry is well documented as a stressful profession. The majority of UK dentists work in general practice, which can carry multiple sources of stress. Previous research has acknowledged the propensity of these sources of stress for general dental practitioners (GDPs) when undertaking clinical, administrative and managerial tasks. The results of these accumulative stress sources can lead to burnout among GDPs. Understanding the environmental drivers of stress is an important step in high, and in some reported cases, unsustainable levels of stress and burnout.

Use of lining materials under posterior resin composite restorations in the UK

ObjectivesTo investigate opinions on, and current use of lining materials prior to the placement of posterior resin composite restorations by general dental practitioners (GDPs) in the UK. A further objective was to investigate aspects of posterior resin composite restoration placement techniques employed by UK GDPs. MethodsA questionnaire was devised to gain the information sought. It was sent to 500 UK dentists, chosen at random from the register of the General Dental Council. ResultsThree hundred and fifty four replies were received, which gave a response rate of 71%. Eighty two percent of respondents reported placing lining materials in deep cavities to be restored with resin composite. Regarding moderately deep cavities, half of the respondents indicated a preference to place a lining material, whilst 44% were not sure if a lining was required. The remaining 6% did not respond to the question. Of the respondents, 39% reported that they did not place lining materials in shallow cavities. Regarding techniques for posterior resin composite placement, two-step etch and rinse systems were the most common adhesive bonding systems used (60%). The majority of respondents (80%) reported not using rubber dam when restoring posterior teeth with resin composite. ConclusionsThere was considerable confusion about the need to place a lining prior to resin composite restorations placement in moderate depth and shallow cavities, whilst most favoured the placement of a lining in deep posterior cavities. The majority of GDPs may not routinely use rubber dam for the placement of posterior resin composite restorations. Clinical significanceDecision making and operative techniques for cavity linings under posterior composite restorations in moderately deep and deep cavities is contentious among dentists, resulting in a need to generate more convincing, practice-relevant data on the use of lining materials to inform the dental profession.

Molar incisor hypomineralisation: experience and perceived challenges among dentists specialising in paediatric dentistry and a group of general dental practitioners in the UK.

To assess the views and experience of the UK dentists specialising in paediatric dentistry (trainees) about molar incisor hypomineralisation (MIH) and compare the findings with the responses from a group of UK general dental practitioners. A web-based questionnaire was sent to dentists undergoing specialist training in paediatric dentistry. The same questionnaire was completed by a group of general dentists who stated an interest in treating children, with various levels of experience. The questionnaire sought information on clinical experience and the views of the dentists on the impact of MIH on children and families. Specialty trainees (37) from different paediatric dental departments in the UK completed the online survey, giving a total response rate of 71%. The questionnaire was also completed by 31 general dental practitioners. There was difficulty in distinguishing MIH from other conditions for both groups. Increased sensitivity of affected teeth was the most frequently encountered problem with 51% of the trainees and 76% of the dentists saying this was often or always a challenge. The trainees were particularly concerned about the pain children experienced and about the appearance of the condition. Both groups felt that parental anxiety occurred in almost all cases. Both groups felt that MIH presents several clinical challenges and has a negative effect on the quality of life of the affected children and their families. There were significant differences in the views and perceptions between the two groups.

The Ability to Identify Early Apical Pathology: A Comparison between UK's General Dental Practitioners and Endodontists

Objectives: To investigate the ability of endodontists and general dental practitioners (GDPs) to interpret early periapical pathology and to examine effect of age, undergraduate education and attendance at courses upon radiographic interpretation. The hypothesis was that there would be no significant difference between GDPs and endodontists. Methods: General dental practitioners (n=603) and endodontists (n=132) had access to high quality images of 12 periapical radiographs. The images had been previously scanned to obtain the same resolution as the original radiograph. Each was presented to observers as an exact replica of the size of a size 2 periapical film. Six radiographs demonstrated the presence of an early periapical lesion on a specific tooth whilst the remaining six radiographs showed normal periodontium. Each radiograph was printed on high quality paper. Each participant was asked to examine a specific tooth for the presence/absence of apical pathosis. Results: The mean sensitivity and specificity for the endodontists was 0.65 and 0.73 respectively and, for the GDPs, mean sensitivity was 0.53 and specificity 0.66. The independent T-test found a significant difference (p<0.001) for both sensitivity and specificity between GDPs and the endodontists. The study also found a significant difference between the sensitivity and specificity of GDPs and their undergraduate education (p-value of 0.01 and <0.001 respectively). GDPs also recorded a significant difference between attending continuing education courses in radiology and their specificity (p< 0.004). Conclusions: Endodontists were more able than GDPs in recognising apical pathology. Attending postgraduate courses in radiology interpretation increased the specificity of GDPs

Five-year clinical evaluation of zirconia-based bridges in patients in UK general dental practices

ObjectivesThis study reported the results at 5 years of fixed-fixed all-ceramic bridges, constructed in a yttria oxide stabilized tetragonal zirconium oxide polycrystal (Y-TZP) substructure, placed in adult patients in UK general dental practices. Materials and methodsFour UK general dental practitioners recruited patients who required fixed bridgework and, after obtaining informed written consent, appropriate clinical and radiographic assessments were completed. The teeth were prepared and bridges constructed in accordance with the manufacturer's instructions. Each bridge was reviewed annually within 3 months of the anniversary of its placement by a calibrated examiner, together with the clinician who had placed the restoration, using modified USPHS criteria. ResultsOf the 41 bridges originally placed, 33 bridges were examined at 5 years. All Y-TZP frameworks were intact and no bridge retainers had debonded. Eight chipping fractures in the veneering ceramic were noted over the 5-year period. In five cases the patients were unaware of these and these cases were polished. Of the remaining three cases, in one a repair was attempted but was unsuccessful, but the bridge remained in satisfactory service. However, in the case involving a chipping fracture of the mesial–incisal angle of a central incisor, it was considered that replacement of the bridge was necessary. Conclusion97% (n=32) of the 33 Lava Y-TZP fixed-fixed bridges, evaluated in patients attending UK general dental practices, were found to be performing satisfactorily. Clinical relevanceThe use of Y-TZP frameworks holds promise.

A clinical evaluation of all-ceramic bridges placed in patients attending UK general dental practices: Three-year results

ObjectivesTo report the results at year three of an evaluation of fixed–fixed all-ceramic bridges, constructed in a yttria oxide stabilized tetragonal zirconium oxide polycrystal (Y-TZP) substructure, placed in adult patients in UK general dental practices and luted using a self-adhesive resin-based cement. MethodsEthical approval was obtained. Four UK general dental practitioners were asked to recruit patients in accordance with the trial protocol. After obtaining informed written consent, appropriate vitality and radiographic assessments were completed and the pre-operative status of the gingival tissues noted. The teeth were prepared and bridges constructed in accordance with the manufacturer's instructions. Each bridge was reviewed annually within 3months of the anniversary of its placement by a calibrated examiner, together with the clinician who had placed the restoration. The examiners evaluated the integrity of the restoration, its anatomic form, marginal adaptation, surface quality, sensitivity, the condition of the adjacent gingivae, and the presence or absence of secondary caries. ResultsA total of 34 bridges were examined at the three-year review. All Y-TZP frameworks were intact and no bridge retainers had debonded. Two veneering ceramic chips, in total, were detected over the three-year period of observation: the patients in whom this had occurred were unconcerned. A further abutment tooth had been successfully endodontically treated, through an occlusal access cavity, in addition to the two already reported at year one. SignificanceAt year three, the 34 Lava Y-TZP fixed–fixed bridges, placed in patients attending UK general dental practices, were found to be performing satisfactorily.

Summary of: The use of clinical photography by UK general dental practitioners

Aim The aim of this study was to assess by means of a postal questionnaire the numbers of general dental practitioners (GDPs) who used clinical photography and for what application. Method The questionnaire was distributed to 1,000 randomly selected dentists in the UK with an explanatory letter and reply paid envelope. The data collected was computerised and analysed statistically. Results Five hundred and sixty-two replies were received. Of the respondents, 48% used clinical photography, with 59% using a digital camera, 34% a 35 mm camera and 19% a video camera. Principal uses of clinical photography were treatment planning (84%), patient instruction/motivation (75%), medico-legal reasons (71%) and communication with the laboratory (64%). Conclusion Clinical photography was used by 48% of general dental practitioner respondents.

A clinical evaluation of all-ceramic bridges placed in UK general dental practices: first-year results

To report the results at year one of a three-year evaluation of the performance of fixed all-ceramic bridges, constructed with a yttrium tetragonal zirconia polycrystal substructure placed in adult patients in UK general dental practices and cemented using a self-adhesive resin-based cement. Ethical approval was obtained. Four UK general dental practitioners were asked to recruit patients complying with the trial criteria and protocol. After obtaining informed written consent, appropriate vitality and radiographic assessments were completed and the pre-operative status of the gingival tissues noted. The teeth were prepared and bridges constructed using the same technician and laboratory procedures. Each bridge was reviewed within three months of the anniversary of its placement by a calibrated examiner together with the clinician who had placed the restoration. The examiners evaluated the integrity of the restoration, its anatomic form, marginal adaptation, surface quality, sensitivity, the condition of the adjacent gingivae, and the presence or absence of secondary caries. All the bridges (n = 38) examined at the first-year review were present, intact and performing well, though one small chip of the veneering porcelain was detected and in two cases an abutment tooth had been endodontically treated through an occlusal access cavity.

Summary of: Evaluation of dentists' perceived needs regarding treatment of the anxious patient

Background With regard to the management of dental anxiety in general dental practice, it has been considered that general dental practitioners (GDPs) are well placed to treat adults with mild forms of dental anxiety. However, little is known about the specific anxiety management techniques being used by GDPs in the UK. Aim To determine the views and experiences of dental practitioners in their current use of anxiety management techniques, their undergraduate and post-graduation training in these techniques and future training needs. Methods A postal questionnaire was sent to a sample of GDPs working in the Midlands region (n = 750) in the UK. Dentists were randomly selected using lists provided by the primary care trusts for each locality. Results The response rate was 73% (n = 550). Of these, 90 were not included in the final analysis due to exclusion criteria set prior to questionnaire release. This left 460 questionnaires for analysis. Eighty-five percent of respondents agreed that dentists had a responsibility to help dentally anxious patients (n = 391). Dentists were asked their reasons for not using anxiety management techniques in practice. Psychological techniques, sedation (oral, inhalation, or intravenous) and hypnosis were reported as not having been used due to the paucity of time available in practice, a shortage of confidence in using these techniques and the lack of fees available under the NHS regulations. Also, 91% reported feeling stressed when treating anxious patients. When asked about the quality of teaching they had received (undergraduate and postgraduate), 65% considered that the teaching was less than adequate in the use of psychological methods, whereas 44% indicated that they would be interested in further training in psychological methods if financial support was available. Conclusion The need for further training in managing the dentally anxious patient is supported by dentists' lack of confidence and inadequate training in treating such patients, as determined from the results of a postal questionnaire to UK GDPs.
