Exploring the attitudes of general dental practitioners to providing dietary advice alongside oral rehabilitation for older adults.

OBJECTIVE: We aimed to capture General Dental Practitioners' (GDPs) views on delivering dietary advice to older adults in combination with treatment to replace missing teeth and identify solutions to help inform the development and implementation of future dietary interventions within primary dental care. BACKGROUND: As natural teeth are lost, older adults may need to choose softer, more manageable foods which might be of lower nutrient density. Previous research has indicated that prosthodontic rehabilitation can improve masticatory function but not the intake of nutrients, highlighting a potential need for a combined approach of oral rehabilitation and dietary counselling. MATERIALS AND METHODS: Semi-structured telephone interviews were conducted with a purposive sampling strategy of 12 GDPs. Interviews were digitally recorded and transcribed verbatim. An iterative coding process using theme-analytic methods was used. RESULTS: Twelve interviews were conducted with GDPs in the United Kingdom. The themes that emerged from the interviews included: the awareness of the importance of dietary advice among GDPs; the concerns GDPs had on patients' adherence to dietary advice; uncertainty over roles and responsibilities in the provision of dietary advice; and the limited time and remuneration for dietary advice in dental practice. A minor theme identified was the motivation of GDPs to implement dietary advice alongside oral rehabilitation. All reported that they were already providing dietary advice to their patients but that this was limited to caries prevention. CONCLUSION: The GDPs interviewed expressed positive attitudes towards providing dietary advice alongside oral rehabilitation for older adults. However, a lack of confidence, awareness, time and remuneration are barriers to its provision in primary dental care. To facilitate the implementation of dietary advice alongside oral rehabilitation, clear guidance on and training in delivering dietary advice and multidisciplinary cooperation are required.

Continuing professional development in general dentistry-experiences of an online flipped classroom.

INTRODUCTION: Continuing professional development is a lifelong learning process. One pedagogical approach that can be used is active learning. Flipped classroom is a method that has been shown to improve deeper conceptual understanding. In an online setting, the method saves travel, time, and costs. To our knowledge, flipped classroom is rarely used in continuing professional education. This study in general dentistry explored experiences of an online flipped classroom course in continuing professional development. MATERIALS AND METHODS: Fifteen dental hygienists, clinically active in general dental care, were interviewed. They were recruited from an online course on the latest classification system for periodontal diseases. The course had been conducted using an active learning and flipped classroom model. The interviews were semi-structured. Data were extracted using qualitative content analysis. RESULTS: The experiences of the dental hygienists could be summarized in three themes: Stimulation of knowledge gain through self-paced studies, The ease of virtual networking among colleagues, and Fostering of direct practical application through collaboration. CONCLUSION: New and emerging communication technology seems to open new possibilities for continuing professional development in general dentistry. Study participants felt that, in an online environment, mixing asynchronous and synchronous communication in a flipped classroom model facilitated learning in continuing professional development. Online active learning seems to work well in continuous professional development in general dentistry. After the course, the participating dental hygienists stated that they were able to use their new knowledge clinically and felt confident doing so.

[Diagnosing neuropathic orofacial pain in the general dental practice]. / Diagnosticeren van neuropathische orofaciale pijn in de algemene tandartspraktijk.

Dental pain is a common reason for patients to visit the dentist. This type of pain is usually easy to diagnose and treat. However, diagnosing and treating other forms of orofacial pain remains complicated. One of the most challenging types of orofacial pain to diagnose and treat is neuropathic orofacial pain: pain resulting from damage to nerve tissue. Recognizing this type of pain in a timely manner can prevent unnecessary invasive dental treatments and disappointment for patients who seek help for this type of pain. There are relatively simple tools for dentists to distinguish neuropathic pain from other types of orofacial pain. The treatment of neuropathic pain is primarily focused on symptom relief through medication.

The referral pattern and treatment modality for peri-implant disease between periodontists and non-periodontist dentists.

OBJECTIVES: This study is to investigate the referral pattern and treatment modality of dentists in the management of peri-implant diseases between periodontists and non-periodontist dentists (NPDs). MATERIALS AND METHODS: A total of 167 validated questionnaires were obtained from periodontists and NPDs, who had experience of placing implants for at least one year. Question I to IV asked how the dentist would respond if a patient came for treatment of their peri-implant diseases with four different scenarios according to resource of patient and disease severity. For each Scenario, dentists also replied which treatment procedures they would use if they decide to treat the patient. RESULTS: Periodontal training, resource of patient, and disease severity were shown to significantly influence the referral pattern and treatment modality in the management of peri-implant disease (p < 0.05). Periodontists were more likely to use variable treatment procedures, including occlusal adjustment (OR = 2.283, p < 0.01), oral hygiene instruction (OR = 3.751, p < 0.001), topical antiseptic agent (OR = 2.491, p < 0.005), non-surgical mechanical therapy (OR = 2.689, p < 0.001), surgical therapy (OR = 2.009, p < 0.01), and remove implant (OR = 3.486, p < 0.001) to treat peri-implant diseases, compared to NPDs. CONCLUSION: The periodontal specialty training, resource of patient, and disease severity significantly influenced the referral pattern and treatment modality of dentist treating an implant diagnosed with peri-implant disease. This study also highlighted the importance of educating basic periodontal and peri-implant disease-related knowledge to all dentists regularly performing dental implant treatments. CLINICAL RELEVANCE: Peri-implant diseases are highly prevalent among patients with dental implants. Periodontal specialty training could enhance using variable treatment procedures to treat peri-implant diseases for dentists.

Knowledge and practice towards early orthodontic problems among general dentists and paediatric dentists.

OBJECTIVES: To assess the knowledge, practice and challenges faced by general dental practitioners (GDPs), paediatric dentists (PDs) and postgraduate paediatric dentistry students (PGPDSs) in diagnosing and managing early orthodontic problems. DESIGN: Cross-sectional study. METHODS: A total of 159 dentists were enrolled in this study (121 GDPs, 21 PDs and 17 PGPDSs). Data were collected using a self-administered questionnaire involving two sections. Section A included questions regarding demographic features and orthodontic practice. Section B included photos of 12 orthodontic cases that needed early intervention. Knowledge and practice were assessed using six questions for each case that was then rated using predefined scores of poor (score <50%), average (score 50%-75%) and good (score >75%). RESULTS: The knowledge scores regarding the identification of early orthodontic problems were average among the three groups with GDPs having the lowest score (P = 0.0001). The knowledge scores regarding the selection of optimal treatment time were average among the PDs and PGPDSs, and poor among GDPs. GDPs tended to refer most of their cases to an orthodontist except for cases of thumb sucking. PDs and PGPDSs were more confident in treating anterior crossbite, thumb sucking habits and delayed eruption of incisors. All participants scored 'poor' regarding the selection of an appropriate orthodontic appliance. There was no significant correlation between knowledge and practice (P > 0.05). CONCLUSION: PDs and PGPDSs showed higher knowledge and practice scores when compared to GDPs. For all three groups included in this study, lack of clinical skills was the main reason for not treating early orthodontic problems.

Present status and future directions: Managing endodontic emergencies.

Endodontic emergencies are common in both general dental practices and specialist Endodontic practices. The aim of this review is to provide an overview of endodontic emergencies. Endodontic emergencies can be a result of many different conditions of the pulp, root canal and periradicular tissues. They may occur before endodontic treatment has been started, between appointments when treatment is being performed over multiple visits, or after endodontic treatment has been completed. In the latter situation, the emergency may be very soon after the treatment or it may occur many years later, in which case it is usually a new disease process as a result of the root canal system becoming infected. An emergency can be a stressful situation for both the patient and the dentist (or endodontist) as it is usually an unexpected event. It is incumbent on dental professionals to provide timely assistance to patients who have an emergency, and it is also important to allow sufficient time to manage the situation comprehensively. Management of endodontic emergencies should follow the principles of the 3D's-Diagnosis, Definitive dental treatment and Drugs-and in that sequence. An accurate diagnosis, the first "D", is essential so the appropriate treatment can be provided. Diagnosis requires a thorough understanding of the various conditions that can cause the emergency and this can be helped by having a comprehensive classification of the various conditions. The diagnosis should also direct the clinician to the appropriate Definitive dental treatment, the second "D". Root canal treatment will not always be required as some cases can be managed conservatively. Other cases may require root canal re-treatment. The specific details of how the treatment are done can also vary, according to the diagnosis. The final "D" is Drugs-the use of drugs should also be dependent on the diagnosis and the dental treatment. Drugs should only be an adjunct following the treatment. The clinician must also differentiate between inflammation and infection in order to provide the appropriate treatment and to prescribe the appropriate medication for effective pain relief and resolution of other symptoms or signs such as swelling.

Dental pedagogy in the 'new normal' COVID-19 era: a transition template of teaching protocols.

AIMS: Delivery of clinical dental education, as opposed to clinical medicine, is particularly challenging due to the obligatory aerosol-generating procedures (AGPs) used in dentistry, which are known to facilitate the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Hence, using AGPs and working in close proximity to patients for extended periods in dental hospital/university settings with multiple teaching clinics have been a formidable prospect for all stake holders. Therefore, several professional and governmental organizations have promulgated variations of infection control guidelines for general practice dentistry in the pandemic era to mitigate SARS-CoV-2 transmission. MATERIALS AND METHODS: In the absence of unified guidelines for modified infection control/clinical procedures for dental education. We implemented a clinical protocol template and modified operating procedures (MOP) for teaching clinical dentistry to fit the infection control requirements during the pandemic/post-pandemic period at the Sharjah University, College of Dentistry, UAE. MOPs ranged from various engineering control measures (e.g., negative-pressure ventilation systems in operatories) to administrative control measures featuring post-procedure fallow periods of treatment-abeyance between patient sessions. RESULTS: The new MOPs for clinical dentistry in the COVID-19 pandemic era, trialled in a UAE dental teaching hospital, have successfully eliminated infection transmission amongst the students, clinicians, ancillary staff, or attending patients, thus far. CONCLUSIONS: The proposed MOPs that complement the standard operating protocols in clinical dentistry were an attempt to mitigate nosocomial infection transmission and protect four different groups of stakeholders, i) the patients, ii) the dental students, iii) the clinical academics, and iv) the para-dental personnel/assistants. Due to the endemicity of the COVID-19 in many regions of the World, the suggested MOPs need periodic review and revision, to fit the emerging data on the disease. Finally, as there are no studies to date comparing the relative efficacy of the MOPs in various dental academic institutions, there is an urgent need for future workers to address this issue.

Influence of dental education on adoption and integration of technological aids in the delivery of endodontic care by dental practitioners: a survey.

OBJECTIVE: To investigate adoption and integration of technological aids during endodontic treatment and where dental practitioners (DPs) learnt to use this technology. MATERIALS AND METHODS: An electronic questionnaire was distributed to all 459 dentists who graduated from University of Bergen between 2008 and 2018. The respondents were divided into two cohorts, older graduates (2008-2013) and newer graduates(2014-2018). RESULTS: A total of 314(68.4%) DPs answered the questionnaire. Magnification in the form of dental operating microscopes (DOM) and dental loupes was used by 180 (59.6%), electronic apex locators (EAL) by 271(89.7%) and motor-driven files by 281 (93.4%) DPs. The most frequent response, as to where they learnt to use them was: during undergraduate dental (UG) education. Significantly more newer graduates (90.7%) performed instrumentation based on what they learnt during UG education (p < .001). Older graduates based their instrumentation method equally on what they learnt during UG education (51.9%) and continuing dental education(42.6%). Rubber dam was used during all treatment procedures by 93% of the DPs. CONCLUSIONS: UG education is a communication channel with long-lasting importance for adoption and integration of technology by DPs. Exposure to innovations (awareness) during UG education is adequate for integration of technology. Continuing dental education is as valuable as UG education for adoption of technology for older graduates.

General dentists' attitudes and perceived barriers in providing domiciliary dental care to older adults in long-term care facilities or their homes in Northern Ireland: A descriptive qualitative study.

OBJECTIVE: Many older patients, housebound or living in long-term care facilities (LTCFs) have limited access to dental care. This descriptive qualitative study aimed to understand general dental practitioners (GDPs) attitudes and perceived barriers to undertaking Domiciliary Dental Care (DDC) for those patients in Northern Ireland (NI). METHODS: Semi-structured telephone interviews were conducted with a purposive sample of 12 GDPs in Northern Ireland. Interviews were digitally recorded and transcribed verbatim. An iterative coding process using theme-analytic methods was used. RESULTS: The data were characterised into four major themes-risk of professional litigation, remuneration for those undertaking DDC, complexity of treatment, and the overall framework of the dental care system in NI. Two minor themes identified were practice culture and reasons for undertaking DDC. The GDPs in the study identified a number of barriers to undertaking DDC including a legal requirement to transport oxygen, lack of organisation and limited oral hygiene care provision in LTCFs, and confusion around their responsibilities for provision of DDC. Those GDPs who were providing DDC indicated that they did so out of kindness and a sense of loyalty to their long-standing patients. CONCLUSION: The GDPs in this study identified a number of significant barriers to provision of DDC at organisational, structural and clinical levels. The GDPs indicated that they required clarification of their responsibilities around DDC with clear guidelines necessary given the increase in demand for this service.

A New Home for Dentistry and Dental Qualifications in the United Kingdom.

The first dental qualification in the UK was awarded by the Royal College of Surgeons of England in 1860. From then on dentistry was closely aligned with, and partly under the thumb, of the medical profession. It thus differed from the USA. Over the years there was slow separation, resulting in 2021 in a new College of General Dentistry.

Ontario Dentists' Practice of Sedation and General Anesthesia: Barriers to Access and Use.

BACKGROUND: To investigate, among Ontario dentists, (1) self-reported barriers to access to sedation and general anesthesia (GA) services and (2) their current use of sedation and GA. METHODS: Of Ontario dentists practising, 3001 were randomly selected to complete a 16-question survey by mail or online in 2011. Mixed analysis of variance (ANOVA) followed by independent-sample t tests or 1-way ANOVA evaluated the relation between dentists' views and demographic variables including sex, clinical experience and size of primary practice. RESULTS: Of the participants (n = 1076; 37.9% response rate), 69.7% were male, 84.4% were general practitioners, mean time in practice was 20.6 years (0.5-42 years) and 42.2% were in cities of over 500 000 people. Most dentists (60.2%) provided anesthesia services, although 38.2% indicated lack of training and the belief that there is no patient demand (25.3%) as reasons not to use anesthesia in their offices. Nitrous oxide was used 17.5% of the time for all dental procedures except implants. Barriers to referral of patients for anesthesia services included high costs associated with sedation/GA (72.2%) and patient fear of anesthesia (33.5%). CONCLUSION: This study identified a perceived lack of patient demand, lack of dentist training, high costs of sedation/GA and patient fear of sedation/GA as primary barriers to use of sedation/GA in Ontario dental practices. The use of various anesthesia modalities is diverse, with 60.2% of dentists providing sedation/GA.

Effects of an individualised training course in endodontics on the knowledge and insights of dentists in Public Dental Service in Norway.

OBJECTIVE: To evaluate the knowledge and insights of general dental practitioners regarding endodontic diagnosis and treatment principles before and after attending a 2-days continuing education course. MATERIALS AND METHODS: Sixty-seven dentists employed in the Public Dental Service in Møre and Romsdal county, Norway, were invited to a continuing education course in endodontics. Before and after the course, they answered a questionnaire weighing the importance of factors influencing the prognosis of endodontic treatment. The same questionnaire was answered by specialists in endodontics (n = 56; Spec Group) and a reference group consisting of general dental practitioners from both private and public practice (n = 21; Ref Group). The Test Group answered both before and after the course, while the Spec and Ref Groups completed the questionnaire once. The responses were compared using the Wilcoxon Sign test and Mann-Whitey U test. RESULTS: Of the 67 dentists in the Test Group, 49 (73%) completed the course and answered both questionnaires. Before attending the course, the Test Group differed significantly from the Spec Group in 18 out of 27 prognostic factors (p ≤ .05). After the course, there was only moderate improvement in the Test Group responses. On only three factors, they agreed significantly more with the specialists than before attending the course (p ≤ .05). After the Test Group participants had attended the course, their responses were comparable to the responses of the Ref Group. CONCLUSIONS: A two-days continuing education course only marginally improved dentists' level of knowledge and insights regarding the influence of prognostic factors in endodontics.

Survival of root filled teeth in general dentistry in a Swedish county: a 6-year follow-up study.

OBJECTIVE: The purpose of the present study was to investigate the survival rate of root filled teeth in general dentistry in a Swedish county and to identify risk predictors with a significant influence on the survival rate. MATERIALS AND METHODS: This is a retrospective 6-year follow-up study on 1642 recall patients with 1720 teeth root filled in general dentistry in the Public Dental Service in the county of Stockholm, Sweden. Background variables were collected from the database at baseline as potential predictors of tooth loss. The outcome variables were extraction during the 6-year follow-up period and the reason for the extraction. Stepwise Cox regression analysis was adopted in order to investigate the influence of the potential risk predictors on the risk for tooth extraction. RESULTS: Nine percent of the root filled teeth were lost after 6 years. The most frequent reason for tooth loss was fracture and/or cracks (58%). The survival rate of the root filled teeth increased significantly for younger patients, root filled teeth with metal crowns (96%) and high quality of the root filling (93%). The survival rate differed significantly between tooth groups with the lowest survival for molars (83%). Composite fillings were significantly associated with lower quality of the root fillings. CONCLUSIONS: Ninety-one percent of the root filled teeth survived after 6 years. The survival rate was significantly higher for teeth with root-fillings of high quality and metal crowns as well as for root filled teeth in younger patients. The lowest survival rate was found for molars.

Radiographic outcome of root canal treatment in general dental practice: tooth type and quality of root filling as prognostic factors.

OBJECTIVE: This study evaluated the radiographic outcome of root canal treatments (RCTs) performed by general dental practitioners (GDPs) with focus on tooth type and quality of root filling. MATERIALS AND METHODS: The target population included all patients receiving root filling by GDPs in City of Helsinki in 2010-2011. Equal numbers of each tooth type (anteriors, premolars, molars) by jaw were included, resulting in 426 teeth. Pre- and post-operative periapical radiographs were assessed to evaluate periapical status and quality of root filling. Statistical evaluation utilized Chi-squared tests, Cohen's kappa and logistic regression modelling. RESULTS: The overall success rate of RCT was 67.4%, being 76.8%, 69.7% and 55.6% (p < .001) for anteriors, premolars and molars, respectively. The quality of root fillings varied by tooth type (p < .001); optimal fillings were least frequent (43%) in molars. In multifactorial analysis, RCTs were more likely to succeed in non-molars (OR = 1.8), in teeth with optimal root fillings (OR = 3.6) and in teeth without apical periodontitis (OR = 3.2). CONCLUSION: The quality of root fillings and radiographic outcome of RCTs varied considerably according to tooth type; success was least likely in molars. Improvement is needed in quality of RCTs by GDPs.

What non-clinical factors influence the general dentist-specialist relationship in Canada?

BACKGROUND: The general dentist-specialist relationship is important for effective patient care and the professional environment. This study explores the non-clinical factors that may influence the general dentist-specialist relationship in Canada. METHODS: A cross-sectional web-based survey of a sample of general dentists across Canada was conducted (N ≈ 11,300). The survey collected information on practitioner (e.g., age, gender, years of practice) and practice (e.g., location, ownership) factors. Two outcomes were assessed: not perceiving specialists as completely collegial and perceiving competitive pressure from specialists. Binary and multivariable logistic regression analysis was conducted. RESULTS: A total of 1328 general dentists responded, yielding a response rate of 11.7%. The strongest associations for perceiving specialists as not completely collegial include being a practice owner (OR = 2.15, 95% CI 1.23, 3.74), working in two or more practices (OR = 1.69, 95% CI 1.07, 2.65), practicing in a small population center (OR = 0.46, 95% CI 0.22, 0.94), and contributing equally to the household income (OR = 0.47, 95% CI 0.26, 0.84). The strongest associations with perceiving medium/large competitive pressure from specialists include having a general practice residency or advanced education in general dentistry (OR = 2.00, 95% CI 1.17, 3.41) and having specialists in close proximity to the practice (OR = 2.52, 95% CI 1.12, 5.69). CONCLUSION: Practitioner and practice factors, mostly related to business and dental care market dynamics, are associated with the potential for strained relationships between general dentists and specialists in Canada. This study points to the need for dental professional organizations to openly discuss the current state of the dental care market, as it has important implications for the profession.

[The oral health of frail home-dwelling elderly in the general practice]. / De mondgezondheid van kwetsbare thuiswonende ouderen die de huisarts bezoeken.

The number of frail home-dwelling elderly is increasing, and they are likely to retain their own dentition longer when ageing. With increasing age, the number of dental visits declines, while the number of visits to the general practitioners' (GP) clinics increases. The aim of this study was to assess the oral health status and dental visits of frail home-dwelling elderly that visit their GP. The study consisted of questionnaires and an oral examination. Subjective and objective oral health was determined by the Geriatric Oral Health Assessment Index-NL and the Oral Health Assessment Tool. Almost half of the frail elderly had not visited the dentist for over 2 years and a quarter had objective oral health problems. The educational level and the dental status were of influence on the dental visits and on their oral health. In about a third of the subjects, a subjective oral health problem was observed, which was influenced by the extent of the subject's frailty. A multidisciplinary approach can improve the oral health status of frail home-dwelling elderly.

Perceptions and practices of general practitioners on providing oral health care to people with diabetes - a qualitative study.

BACKGROUND: Poorly controlled diabetes leads to multiple complications including oral health problems. General practitioners (GPs) are at the forefront of management of chronic diseases in primary health care. Diabetes guidelines encourage a proactive role for GPs in oral health complications management in people with diabetes, yet little is known about this area of care. This study aimed to explore current practices, perceptions and barriers of GPs towards oral health care for people with diabetes. METHODS: We employed a qualitative research method utilising telephone interviews. Purposive and snowball sampling were used to recruit 12 GPs from Greater Sydney region. A thematic analysis involving an inductive approach was used to identify and analyse contextual patterns and themes. RESULTS: A majority of participants were males (n = 10), working in group practices (n = 11) with a mean ± SD age of 55 ± 11.4 years and 25 ± 13.6 years work experience. Three major themes emerged: oral health care practices in general practice settings; barriers and enablers to oral health care; and role of diabetes care providers in promoting oral health. Most GPs acknowledged the importance of oral health care for people with diabetes, identifying their compromised immune capacity and greater risks of infections as risk factors. GPs reported 20-30% of their patients having oral health problems, however their current oral health care practices relating to education, risk assessment and referrals were reported as very limited. GPs identified several barriers including time constraints, absence of referral pathways, and limited knowledge and training in promoting oral health care. They also reported patient barriers including oral health care costs and lower oral health awareness. GPs perceived that resources such as education/training, a standardised assessment tool and patient education materials could support them in promoting oral health care. GPs also perceived that other diabetes care providers such as diabetes educators could play an important role in promoting oral health. CONCLUSIONS: Despite current recommendations, GPs' current oral health care practices among people with diabetes are limited. Further strategies including capacity building GPs by developing appropriate oral health training programs and simple risk assessment tools along with accessible referral pathways are needed to address the current barriers.

Dentists' perceptions of their professional roles regarding referrals within primary dental care in England: a qualitative study.

OBJECTIVE: To describe dentists' perceptions of their professional roles, including the reasons why they make, accept or decline patient referrals within primary dental care in England. BASIC RESEARCH DESIGN: Qualitative semi-structured interviews, conducted via Skype, telephone or face-to-face. Transcripts were analysed using thematic analysis and typologies were developed. PARTICIPANTS: Ten general dental practitioners (GDPs) and 12 community dentists working in England. RESULTS: Five main themes were identified: professional independence, the nature of dental care, the business of dentistry, obscure rules and 'no man's land'. This final theme described a notional gap between GDPs' and community dentists' responsibilities towards vulnerable people, who were perceived by participants to include frail older people, anxious and socially marginalised adults and children with high levels of disease. Three typologies of dentists were generated. 'Entrepreneurs' felt no allegiance to the National Health Service and no obligation to treat vulnerable patients. 'Altruistic carers' were committed to caring for exceptionally deserving patients. 'Pragmatic carers' tried to provide relational dental care (time and emotional support) for vulnerable patients but encountered discouraging systemic barriers. CONCLUSION: Dentists' perceptions of their roles may influence whether and how they provide access to primary dental care for vulnerable people through referral systems. Access issues may exacerbate the oral health inequalities experienced by vulnerable groups. Based upon the findings, approaches are proposed that may encourage and enable the dental workforce to support vulnerable people actively to receive primary dental care.

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.

Knowledge Translation Among General Dental Practitioners in the Field of Periodontics.

INTRODUCTION: Evidence-based practice (EBP) is an expectation of medical professionals and is positively received in the dental community. Investigations of evidence-based dentistry (EBD) have discussed its use in broad terms and daily clinical practice, but there is only limited information about its use and barriers with respect to particular dental specialities. METHODS: A cross-sectional questionnaire was developed to survey implementation and obstacles to EBP; EBD specific to periodontics; and preferences for types of dissemination of evidence. The target population was active general dentists in Nova Scotia (n = 446). An email link to the questionnaire was distributed to dentists, and reminders were sent 4 and 10 days later. RESULTS: The response rate was limited (16.6%). Most respondents were comfortable evaluating the growing body of research, although many reported use of low-level evidence, including that from other health professionals or expert opinion. A common barrier to use was insufficient time. Respondents who found strong evidence for certain periodontal procedures were more likely to refer these procedures, which included tissue regeneration and periodontics related to endodontics. On-site lecture-based dissemination was preferred by most respondents. CONCLUSION: General evidence-based concepts and use were similar to EBD results reported elsewhere, although external validity is limited by our low response rate and narrow target population. Specific data related to periodontics may be useful in directing a modified questionnaire to a broader target population. Respondents who are truly interested in EBD and responded to our questionnaire may ultimately benefit the most from our results, where further educational opportunities can be tailored to overcome the identified barriers and aid in more effective translation of evidence-based periodontal decisions in a general dental practice.
