Life satisfaction of Taiwanese dental graduates received residencies in the U.S.: a cross-sectional study.

BACKGROUND: Each year, more than 200 international dental graduates start U.S. specialty trainings to become specialists. It is unknown if their life satisfaction is associated with any dental career-related factor before residencies (e.g. dental school class rank, research experience, or private practice experience) and after residencies (e.g. staying in the U.S., teaching status, workplace, or board certification). This cross-sectional study aimed to identify these potential factors by surveying Taiwanese dental graduates who pursued U.S. residencies. METHODS: Life satisfaction was measured with a structured questionnaire, Satisfaction With Life Scale (SWLS), which includes five statements on a 5-point Likert scale. Online surveys were sent out to 290 Taiwanese dental graduates who were known to pursue U.S. residencies. T-test, one way analysis of variance, and multivariable adjusted generalized linear model (GLM) were used to assess the differences of mean SWLS scores from different variables. RESULTS: Surveys were completed by 158 dentists. Mean SWLS score of 125 specialists was higher (p = 0.0007) than the score of 33 residents. For the 125 specialists, multivariable adjusted GLM demonstrated better life satisfaction was positively associated with multiple independent factors, such as having research experience, being ranked in the top 26 ~ 50% of the class in dental school, starting U.S. residency within 4 years after dental school, starting residency before year 1996, and specializing in endodontics (vs. periodontics). Life satisfaction was not associated with any factors after residency (e.g. staying in the U.S. afterwards, teaching status, or workplace), but better mean life satisfaction score was significantly associated with being American specialty board certified (p < 0.001) for the specialists in the 26 ~ 75% of their class in dental school. For the 33 residents, better mean life satisfaction score was associated with better dental school class rank in both bivariate (p = 0.020) and multivariable adjusted GLM (p = 0.004) analyses. CONCLUSIONS: The life satisfaction of Taiwanese dental graduates pursuing U.S. residencies might be associated with some professional factors, such as research experience, dental school class rank, residency timing, specialty type, and specialty board certification. We hope our results may provide some objective information on making career decisions for international dental graduates/students who are preparing for U.S. residency.

Indications for root canal treatment in asymptomatic teeth with various radiographic findings: guidelines for general dental practice.

OBJECTIVES: The purpose of this article was to propose guidelines for dental practitioners facing the dilemma whether to treat, follow up, or disregard random asymptomatic radiographic findings. DATA SOURCES: Searches performed in MEDLINE, Cochrane, and EMBASE databases were followed by a manual search. Related data incorporated by experts included recommendations on asymptomatic root canal treatment, quality of the root canal, and restoration relative to outcome. Evidence tables were developed following quality and inclusion criteria assessment. RESULTS: The initial search retrieved 2,796 MEDLINE, 542 EMBASE, and 152 Cochrane articles, for a total of 3,490 potential articles. After duplicates were removed, 2,946 articles remained. Articles not related to the topic and not meeting eligibility criteria were excluded, resulting in 44 studies included in this scoping review. CONCLUSIONS: The proposed guidelines provide easy access to existing information in endodontics. The findings are common and possess clinical and medico-legal importance.

Knowing in general dental practice: Anticipation, constraint, and collective bricolage.

RATIONALE, AIMS, AND OBJECTIVES: Much of the literature concerned with health care practice tends to focus on a decision-making model in which knowledge sits within the minds and bodies of health care workers. Practice theories de-centre knowledge from human actors, instead situating knowing in the interactions between all human and non-human actors. The purpose of this study was to explore how practice arises in the moment-to-moment interactions between general dental practitioners (GDPs), patients, nurses, and things. METHOD: Eight GDPs in two dental practices, their respective nurses, 23 patients, and material things were video-recorded as they interacted within clinical encounters. Videos were analysed using a performative approach. Several analytic methods were used: coding of interactions in-video; pencil drawings with transcripts; and dynamic transcription. These were used pragmatically and in combination. Detailed reflective notes were recorded at all stages of the analysis, and, as new insights developed, theory was sought to help inform these. RESULTS: We theorized that knowing in dental practice arises as actors translate embodied knowing through sayings and doings that anticipate but cannot predict responses, that knowing is constrained by the interactions of the practice but that the interactions at the same time are a collective bricolage-using the actors' respective embodied knowing to generate and solve problems together. CONCLUSION: Practices are ongoing ecological accomplishments to which people and things skilfully contribute through translation of their respective embodied knowing of multiple practices. Based on this, we argue that practices are more likely to improve if people and things embody practices of improvement.

Assessing a training programme for primary care dental practitioners in endodontics of moderate complexity: Pilot data on skills enhancement and treatment outcomes.

Aims: To explore the impact of dedicated training to extend the skills of primary care practitioners on the quality of endodontic care, using clinical, radiographic and patient-related outcomes. Methods: The quality of endodontic treatment performed at the beginning and end of training to become dentists with extended skills (DES) in endodontics was assessed in vitro and in vivo from endo-training blocks and self-reported logbooks containing clinical notes and radiographs respectively. The quality of endodontic care delivered by DES post-training was measured using clinical and radiographic outcomes. Patient-related outcomes were assessed using a self-report questionnaire, including the Oral Health Impact Profile ­ Endodontic Outcome Measure (OHIP-EOM). Results: Data on eight dentists were examined pre-and post-training, five of whom participated in further follow-up investigations on the quality of endodontic care delivered to their patients. Significant improvements in skills were seen for all domains in vitro (p <0.05), and for all domains of the clinical treatment process, and achieving the correct working length of the root filling as seen by radiography in vivo (p <0.05). The quality of the clinical process was maintained following training. Positive patient outcome (OHIP-EOM) scores were recorded (mean score of 34.72, SD = 10.74, n = 120 pre-treatment and 25.85, SD = 7.74, n = 47 representing reduced impact at follow-up). The majority of patients reported being satisfied, or very satisfied, with the service they received (72.5%, n = 98); would use the service again (68.1%, n = 92); and would recommend the service to friends and family (74.8%, n = 101). Conclusions: Findings suggest that training for dentists working in practice can be successful in enhancing skills and changing practice, with evidence of high patient satisfaction and good clinical and patient-related outcomes. Pilot results must be interpreted with caution and further research is required.

Medical emergencies in dental practice - management requirements and international practitioner proficiency. A scoping review.

The management of medical emergencies is widely considered a requisite skill for all dentists. Timely intervention of an emergency can significantly alter the outcome for a patient's morbidity and possible mortality. This scoping review examines the prevalence of medical emergencies in dental practice, as well as dentists' attitude, confidence, and competence, of medical emergency management within a dental setting. Key findings include a lack of preparedness towards medical emergencies, despite a universal recognition of the importance and desire to improve key medical skills.

INTERVAL (investigation of NICE technologies for enabling risk-variable-adjusted-length) dental recalls trial: a multicentre randomised controlled trial investigating the best dental recall interval for optimum, cost-effective maintenance of oral health in dentate adults attending dental primary care.

BACKGROUND: Traditionally, patients at low risk and high risk of developing dental disease have been encouraged to attend dental recall appointments at regular intervals of six months between appointments. The lack of evidence for the effect that different recall intervals between dental check-ups have on patient outcomes, provider workload and healthcare costs is causing considerable uncertainty for the profession and patients, despite the publication of the NICE Guideline on dental recall. The need for primary research has been highlighted in the Health Technology Assessment Group's systematic review of routine dental check-ups, which found little evidence to support or refute the practice of encouraging 6-monthly dental check-ups in adults. The more recent Cochrane review on recall interval concluded there was insufficient evidence to draw any conclusions regarding the potential beneficial or harmful effects of altering the recall interval between dental check-ups. There is therefore an urgent need to assess the relative effectiveness and cost-benefit of different dental recall intervals in a robust, sufficiently powered randomised control trial (RCT) in primary dental care. METHODS: This is a four year multi-centre, parallel-group, randomised controlled trial with blinded outcome assessment based in dental primary care in the UK. Practitioners will recruit 2372 dentate adult patients. Patient participants will be randomised to one of three groups: fixed-period six month recall, risk-based recall, or fixed-period twenty-four month recall. Outcome data will be assessed through clinical examination, patient questionnaires and NHS databases. The primary outcomes measure gingival inflammation/bleeding on probing and oral health-related quality of life. DISCUSSION: INTERVAL will provide evidence for the most clinically-effective and cost-beneficial recall interval for maintaining optimum oral health in dentate adults attending general dental practice. TRIAL REGISTRATION: ISRCTN95933794 (Date assigned 20/08/2008).

State governance versus dentists' autonomy - the case of Swedish dental care.

OBJECTIVE: A trend towards the state governance of healthcare through quality indicators and national clinical guidelines has been observed, and it is argued that this trend can be a challenge to the autonomy of healthcare professionals. In Sweden, these regulatory tools have been implemented in combination with subsidies for adult dental care that are based on guideline recommendations which serve to ensure that dental care is evidence-based and cost-effective. This paper aims to analyse the implications of these changes regarding dentists' autonomy and whether the government's political intentions can be fulfilled. MATERIAL AND METHODS: The paper is based on documents from government authorities and professional theories. RESULTS: The financial control over Swedish dental care has been strengthened, and it can be argued that this is a step in the right direction from a societal point of view, as public resources are limited. Dentists' professional autonomy with their patients is not affected, which is appropriate, as patients should be treated according to their individual needs and expectations. CONCLUSIONS: This article shows that the state's governance does not directly detail dentists' work, which indicates a balance between state governance and dentists' autonomy. However, further research is required to get knowledge on Swedish dentists' view of the governance.

Outcome measures for oral health based on clinical assessments and claims data: feasibility evaluation in practice.

BACKGROUND: It is well known that treatment variation exists in oral healthcare, but the consequences for oral health are unknown as the development of outcome measures is still in its infancy. The aim of this study was to identify and develop outcome measures for oral health and explore their performance using health insurance claims records and clinical data from general dental practices. METHODS: The Dutch healthcare insurance company Achmea collaborated with researchers, oral health experts, and general dental practitioners (GDPs) in a proof of practice study to test the feasibility of measures in general dental practices. A literature search identified previously described outcome measures for oral healthcare. Using a structured approach, identified measures were (i) prioritized, adjusted and added to after discussion and then (ii) tested for feasibility of data collection, their face validity and discriminative validity. Data sources were claims records from Achmea, clinical records from dental practices, and prospective, pre-determined clinical assessment data obtained during routine consultations. RESULTS: In total eight measures (four on dental caries, one on tooth wear, two on periodontal health, one on retreatment) were identified, prioritized and tested. The retreatment measure and three measures for dental caries were found promising as data collection was feasible, they had face validity and discriminative validity. Deployment of these measures demonstrated variation in clinical practices of GDPs. Feedback of this data to GDPs led to vivid discussions on best practices and quality of care. The measure 'tooth wear' was not considered sufficiently responsive; 'changes in periodontal health score' was considered a controversial measure. The available data for the measures 'percentage of 18-year-olds with no tooth decay' and 'improvement in gingival bleeding index at reassessment' was too limited to provide accurate estimates per dental practice. CONCLUSIONS: The evaluated measures 'time to first restoration', 'distribution of risk categories for dental caries', 'filled-and-missing score' and 'retreatment after restoration', were considered valid and relevant measures and a proxy for oral health status. As such, they improve the transparency of oral health services delivery that can be related to oral health outcomes, and with time may serve to improve these oral health outcomes.

Variation in caries treatment proposals among dentists in Norway: the best interest of the child.

AIM: To explore variation in treatment-related-decisions for severe caries in children among dentists in the Public Dental Service (PDS) in Norway. It was also to evaluate the treatment choices in relation to the best interest of children and a child's rights to enjoy the highest standard of health care. METHODS: A pre-coded questionnaire was sent electronically to all general dental practitioners (GDPs) working in the PDS in eight counties in Norway (n = 611). The questionnaire included two case scenarios to reflect common dental conditions related to severe caries among 5-year-old children. Paediatric dentists and paediatric students were invited to validate the different treatment options. Frequency distributions and statistical analyses were carried out using Chi square statistics. RESULTS: The response rate was 65% (n = 391) among the GDPs. A majority of the GDPs preferred a new appointment with behaviour management techniques (BMT) to a child presenting pulpitis and pain. Dentists educated outside the Nordic region would use restraint more often as a treatment alternative when the child was in pain than Nordic-educated dentists (p\0.05). Dentists with less than 10 years of experience preferred BMT and sedation more often when the child was in pain than their older colleagues, who, however, preferred a waiting approach and no immediate treatment if the child was not in pain(p\0.05) [corrected]. CONCLUSIONS: Use of BMT and sedation is related to region of education and years of experience. Awareness of ethical principles with the child´s best interest in mind, should receive increased attention.

Development of quality measurement instruments for root canal treatment.

AIM: To devise measurement instruments for 'quality' of root canal treatment to assess training and outcome of general dental practitioners working within primary care settings. METHOD: Scoring systems relating to quality of root canal treatment were developed using expert consensus and published literature. Domains scored included the Treatment Process, Quality of the Obturation, Clinical Healing, Radiographic Healing and Tooth Complexity. Scoring systems were applied to 10 clinical cases treated by each dentist at the beginning and 10 cases treated at the end of their clinical training and 135 cases treated after completion of training. The dentists recorded the treatment process and clinical healing in clinical logs. Two examiners independently scored the radiographs after undertaking calibration and training. Inter- and intra-examiner reliability of scoring radiographic outcomes was tested using Cohen's Kappa statistics. RESULTS: An instrument was created with four domains to assess quality (two for process and two for outcome of root canal treatment), and a measure of case complexity. Domains of treatment process (n = 240 teeth), outcome (n = 32 teeth) and complexity (n = 215 teeth) were scored using radiographs. The Kappa scores for intra-examiner reliability between 0.22 and 1, whilst inter-examiner reliability ranged between 0.18 and 0.99. CONCLUSION: Evidence-based scores for assessment of the quality (process and outcome) and complexity (structure) of root canal treatment were devised. They were reliable, provided that clinicians were trained in record keeping and examiners have in depth training and calibration in the use of the instruments.

Changes in division of labour and tasks within public dentistry: relationship to employees work demands, health and work ability.

OBJECTIVE: By 2023, fewer dentists are expected in Sweden, at the same time as the demand for dental care is expected to increase. Older people, in particular, are expected to require more dental health than previous generations. To meet this demand, the public sector dentistry in Sweden is moving towards changes in division of labour among dental professionals, including dentists, dental hygienists and dental nurses. However, the impact of this reallocation on the physical and psychosocial wellbeing of employees is unknown. The aim of this study was to compare workplaces with an equal or larger proportion of dental hygienists than dentists (HDH) with workplaces with a larger proportion of dentists than dental hygienists (HD) on the physical and psychosocial work load, musculoskeletal and psychosomatic disorders and sickness presence. MATERIAL: A total of 298 persons employed in the Public Dental Service in a Swedish County Council participated in this study. CONCLUSION: The medium large clinics HDH reported 85% of employee's with considerably more high psychosocial demands compared to employees in medium HD (53%) and large HD (57%). Employees in medium large clinics HDH also reported sleep problems due to work (25%) compared with employees in medium large clinics HD (6%), large clinics HD (11%) and small clinics HDH (3%). Clinic size does not seem to influence the outcome of the HD and HD clinics to any great extent. Of all employees, about 94-100% reported high precision demands and 78-91% poor work postures.

Periodontal diagnosis in private dental practice: a case-based survey.

BACKGROUND: Despite the prevalence of periodontitis in Australia, there are few reports regarding periodontal diagnosis and therapies in the general dental practice setting. This study aimed to assess the degree of diagnostic accuracy in periodontal cases of Victorian general dental practitioners. METHODS: Following ethics approval, dentists were invited to complete a scenario-based questionnaire on the Australian Dental Association Victorian Branch (ADAVB) website. Five text-based clinical scenarios (from a total of 10) were randomly presented, representing patients with a range of disease levels from periodontal health/gingivitis to severe periodontitis, and respondents were asked what examinations they would usually perform. Based upon the presented results of periodontal and radiographic examinations, a periodontal diagnosis was requested. RESULTS: One hundred and thirty-five dentists attempted the survey. Most were in group practice and based in Melbourne; 22.5% of respondents worked in a practice employing a hygienist. The clinical parameters most commonly measured to diagnose periodontal disease were pocket depth and mobility. The majority of respondents diagnosed health, gingivitis and mild periodontitis correctly compared to American Academy of Periodontology guidelines. However, moderate periodontitis tended to be diagnosed as severe. CONCLUSIONS: Dentists in Victoria used appropriate clinical parameters when assessing periodontal disease and were generally accurate in their diagnoses. There is a need for consensus regarding diagnostic definitions.

Long-term validity and reliability of a patient survey instrument designed for general dental practice.

AIM: To consider the extent to which the validity and reliability of the Denplan Excel Patient Survey (DEPS) has been confirmed during its development and by its use in general dental practice and to explore methods by which any survey instrument used in general dental practice might be validated and tested for reliability. METHODS: DEPS seeks to measure perceived practice performance on those issues considered to be of greatest importance to patients. Content validity was developed by a literature review and tested in a pilot study. Criterion validity was tested by comparing patient retention in a payment plan for practices achieving the highest DEPS scores with those attaining the lowest scores over a two year period (surveys completed between 2010 and 2012). Reliability was assessed using the test/re-test method for 23 practices with approximately a three year time interval between tests. Internal consistency was tested by comparing Net Promoter Scores (NPS - which is measured in DEPS) attained by practices with their Patient Perception Index (PPI) as measured by the ten core questions in DEPS. RESULTS: Practices in the pilot study strongly endorsed the content validity of DEPS. The 12 practices with the highest scores in the DEPS slightly increased their number of patients registered in Denplan payment plans during a two year period. The 12 lowest scoring practices saw 7% of their patients de-register during the same period. The 23 practices selected for the test/re-test study averaged more than 250 responses for both the test and re-test phases. The magnitude and pattern of their results were similar in both phases, while, on average, a modest improvement in results was observed. Internal consistency was confirmed as NPS results in DEPS closely mapped PPI results. The higher the measurement of perceived quality (PPI) the more likely patients were to recommend the practice (NPS). CONCLUSION: Both through its development and use over the last four years The DEPS has demonstrated good validity and reliability. The authors conclude that this level of validity and reliability is adequate for the clinical/general care audit purpose of DEPS and that it is therefore likely to reliably inform practices where further development are indicated. It is important and quite straightforward to both validate and check the reliability of patient surveys used in general dental practice so that dental teams can be confident in the instrument they are using.
