Use of scientific evidence by dentists in Brazil: Room for improving the evidence-based practice.

ABSTRACT: This study investigated the use of scientific evidence and the practice of evidence-based dentistry (EBD) among dentists working in Brazil. An online questionnaire was emailed to dentists registered with Brazilian state dental councils. The questionnaire assessed the demographic, educational, and work characteristics of the sample, along with habits in reading scientific articles and other updating resources. Data were analyzed descriptively and by using Bonferroni, Kruskal-Wallis, ANOVA, and T-test statistical methods (? = 0.05). A total of 795 responses were received between June, 2015 and January, 2016. The response rate was not calculated because it was not possible to determine precisely how many dentists received these e-mails. Over 77% of the responding dentists completed postgraduate training. They referred mainly to books, scientific or clinical journals, conferences, and short-term courses for updating their knowledge. Dentists who reported having a habit of reading scientific journals (60.9%) showed a preference for reading case reports, clinical research articles, and literature reviews. Most dentists (77.5%) reported changing their clinical behaviors or procedures based on information gleaned from journal articles. The types of articles that led them to change their clinical practices were primarily clinical research articles and case reports. Working in the public sector was also associated with a lower prevalence of a habit of reading scientific journals and practicing EBD (i.e., self-reported practice). The results suggest that dentists are interested in reading journal articles, especially those addressing clinical outcomes, and that there is room for improving the practice of EBD, particularly in the public sector.

Project description:The aim of this online cross-sectional study is to identify the sources of scientific information used by Brazilian dentists in clinical decision-making and the barriers that they perceive as important to the incorporation of scientific evidence into clinical practice. A pretested questionnaire created in Google Forms which was made available to participants through links sent by e-mail or shared on Facebook® and Instagram® was used to collect the data between October 2018 and May 2019. Only dentists who were involved in direct or indirect care of patients (i.e. clinicians who performed dental procedures or dental educators who participated in the clinical training of graduate or postgraduate dental students) were asked to complete the questionnaire. The sample was comprised of 528 dentists (the response rate from the alumni database was 6.9%); their mean age was 45.2 years (±12.5) and 30.9% had an academic position. The majority were women (68.0%) and lived in Southern or Southeastern Brazil (96.0%). The sources of scientific information more frequently used by them in clinical decision-making were clinical guidelines (65.1%; 95% CI: 60.9, 69.2), scientific articles (56.8%; 95%CI: 52.5, 61.1) and bibliographic databases (48.3%; 95% CI: 43.9, 52.6). The information resource less frequently used was social media. The most important barriers to the clinical use of scientific evidence were: difficulty in determining whether scientific contents found on the Internet were reliable or not (41.8%; 95% CI: 37.6, 46.2), high cost of access to scientific papers (37.7%; 95% CI: 33.5, 41.9), and lack of time for reading scientific articles (32.4%; 95% CI: 28.4, 36.6). Although Brazilian dentists show a positive attitude towards obtaining scientific evidence from reliable sources, there still remain important barriers to the translation of evidence into practice. This can have significant implications for quality of care and should be further investigated.

Project description:BackgroundDental caries are largely preventable, and epidemiological evidence for a relationship between diet and oral health is abundant. To date, however, dentists' perceptions about the role of diet and dentists' practice patterns regarding diet counseling have not been clarified.ObjectiveTHE PURPOSES OF THIS STUDY WERE TO: (1) examine discordance between dentists' perception of the importance of diet in caries treatment planning and their actual provision of diet counseling to patients, and (2) identify dentists' characteristics associated with their provision of diet counseling.DesignThe study used a cross-sectional study design consisting of a questionnaire survey in Japan.ParticipantsThe study queried dentists working in outpatient dental practices who were affiliated with the Dental Practice-Based Research Network Japan (JDPBRN), which aims to allow dentists to investigate research questions and share experiences and expertise (n?=?282).MeasurementDentists were asked about their perceptions on the importance of diet and their practice patterns regarding diet counseling, as well as patient, practice, and dentist background data.ResultsThe majority of participants (n?=?116, 63%) recognized that diet is "more important" to oral health. However, among participants who think diet is "more important" (n?=?116), only 48% (n?=?56) provide diet counseling to more than 20% of their patients. Multiple logistic regression analysis suggested that several variables were associated with providing diet counseling; dentist gender, practice busyness, percentage of patients interested in caries prevention, caries risk assessment, and percentage of patients who receive blood pressure screening.ConclusionsSome discordance exists between dentists' perception of the importance of diet in caries treatment planning and their actual practice pattern regarding diet counseling to patients. Reducing this discordance may require additional dentist education, including nutritional and systemic disease concepts; patient education to increase perception of the importance of caries prevention; or removing barriers to practices' implementation of counseling.Trial registrationClinicalTrials.gov NCT01680848.

Project description:ObjectiveThe purposes of this study were to (1) quantify dentists' practice patterns regarding caries prevention and (2) test the hypothesis that certain dentists' characteristics are associated with these practice patterns.DesignThe study used a cross-sectional study design consisting of a questionnaire survey.ParticipantsThe study queried dentists who worked in outpatient dental practices who were affiliated with the Dental Practice-Based Research Network Japan, which seeks to engage dentists in investigating research questions and sharing experiences and expertise (n=282).MeasurementDentists were asked about their practice patterns regarding caries preventive dentistry. Background data on patients, practice and dentist were also collected.Results38% of dentists (n=72) provided individualised caries prevention to more than 50% of their patients. Overall, 10% of the time in daily practice was spent on caries preventive dentistry. Dentists who provided individualised caries prevention to more than 50% of their patients spent significantly more time on preventive care and less time on removable prosthetics treatment, compared to dentists who did not provide individualised caries prevention. Additionally, they provided oral hygiene instruction, patient education, fluoride recommendations, intraoral photographs taken and diet counselling to their patients significantly more often than dentists who did not provide individualised caries prevention. Multiple logistic regression analysis suggested that the percentage of patients interested in caries prevention and the percentage of patients who received hygiene instruction, were both associated with the percentage of patients who receive individualised caries prevention.ConclusionsWe identified substantial variation in dentists' practice patterns regarding preventive dentistry. Individualised caries prevention was significantly related to provision of other preventive services and to having a higher percentage of patients interested in caries prevention, but not to the dentist's belief about the effectiveness of caries risk assessment.

Project description:OBJECTIVES:This study quantified and compared practice patterns of treatment for deep occlusal carious lesions among Japanese dentists, and tested the hypothesis that dentist characteristics are significantly associated with the decision to choose an indirect pulp capping (IPC), a form of selective carious tissue removal that involves leaving a thin layer of demineralized tissue over the pulp, that is then covered with a protective liner. METHODS:This cross-sectional study was conducted using a questionnaire survey of dentists affiliated with the Dental Practice-based Research Network Japan (n?=?297). Dentists were asked to indicate what percentage of time they use three treatment options when treating patients with deep occlusal caries and possible mild pulpitis on a posterior tooth. Response options were "1. Stop before removing all caries and perform an IPC", "2. Remove all caries and proceed with a direct pulp cap", and "3. Remove all caries and proceed with endodontic-related procedures". Percentages of options 1-3 were compared by multiple comparison. Associations between dentist characteristics and a higher percentage of IPC provision (option 1) were analyzed via logistic regression. RESULTS:Responses were obtained from 206 dentists. Median percentages (interquartile ranges) of options 1, 2 and 3 were 30% (10-59%), 10% (0-30%), and 40% (19-80%), respectively. The differences between option 3 and options 1 and 2 were significant (p?<?0.001). In logistic regression analysis, a higher frequency of obtaining evidence from English-language scientific articles was significantly associated with a higher percentage of IPC, with an odds ratio of 2.28 (95%CI: 1.14-4.54). CONCLUSIONS:Endodontic-related procedures remain the most frequent treatment option for deep occlusal caries. Frequent use of evidence-based information in English-language scientific articles was associated with Japanese dentists' preference toward IPC. CLINICAL SIGNIFICANCE:Japanese dentists would most frequently choose endodontic-related procedures, followed by IPC and direct pulp capping for treatment of patients with deep occlusal caries with possible mild pulpitis on posterior teeth. Significant association was identified between use of evidence-based information in the English-language scientific literature and Japanese dentists' preference for IPC.
