Article Synopsis
  • The study aimed to identify and compare factors contributing to the evidence-practice gap (EPG) in dentistry between Japan and Brazil as perceived by dentists and explore mechanisms to address the gap.
  • A web-based questionnaire was used to collect data from 136 Japanese and 110 Brazilian dentists, focusing on factors causing the EPG.
  • Results showed common issues in both countries, like prioritizing personal experiences over evidence, but also highlighted country-specific challenges, with recommendations for improving evidence-based dentistry (EBD) education and resources tailored to each country's context.

Objectives: This study was designed to: 1) evaluate and compare the evidence-practice gap (EPG) in minimal intervention dentistry (MID) in Japan and Brazil by measuring concordance between dentists' clinical practice and published evidence; and 2) identify dentists' factors associated with the EPG in both countries.

Methods: We performed a cross-sectional study using a web-delivered questionnaire among 136 Japanese and 110 Brazilian dentists. The questionnaire consisted of three questions concerning "restoration diagnosis and treatment," "deep caries diagnosis and treatment," and "caries risk assessment" regarding MID.

Objectives: To identify causes of the evidence-practice gap (EPG) in dentistry in Japan and analyze whether these causes are associated with: (a) improvement of EPG in minimal intervention dentistry (MID) following an educational intervention and (b) specific dentist characteristics.

Methods: We conducted a mixed-methods questionnaire survey among 197 Japanese dentists that integrated both quantitative and qualitative data. Causative factors for the EPG identified in the quantitative survey were clarified by qualitative analysis.

Objectives: To understand patients' comfort with health risk assessments (HRAs) and patient and dentist factors associated with the provision of HRAs.

Methods: In this cross-sectional study, 857 patients seen by 30 dental practitioners in the United States National Dental Practice-Based Research Network reported their comfort receiving HRA for six risk factors (tobacco use, alcohol use, dietary sugar intake, human immunodeficiency virus risks, human papillomavirus risks and existing medical conditions) and whether they discussed any of the risk factors during their visits. Multi-level logistic models were used to examine the impacts of patient, practitioner, practice characteristics on the (1) number of risk factors patients were comfortable discussing and (2) number of risk factors assessed in the current dental visit.

Objectives: To determine whether: the evidence-practice gap (EPG) in minimal intervention dentistry (MID) can be improved by a tailored web-based intervention, and specific clinical situations might impede implementing MID.

Methods: We conducted a before-after intervention study and a qualitative study. Two web-based questionnaire surveys were conducted among 197 Japanese dentists.

Article Synopsis
  • The study aimed to analyze the treatment and monitoring outcomes of cracked posterior teeth over three years, involving 2,858 patients treated by 209 dentists across the USA.
  • Results showed a high survival rate of over 98% for cracked teeth, with a low failure rate (14%) for those that were treated restoratively.
  • The study concluded that dentists can successfully assess whether cracked teeth should receive treatment or simply be monitored, with around 80% continuing to be monitored without requiring additional treatment during the study period.

Objectives: To evaluate the status of teaching of repair of defective resin-based composite restorations in dental schools in the Middle Eastern and North African (MENA) countries.

Methods: A validated 14-item questionnaire was mailed to the directors of the operative/restorative dentistry department in 40 MENA dental schools. Data were collected on teaching, including whether the repair of resin-based composite restorations was part of the dental school curriculum; the rationale behind the teaching; how techniques were taught, indications for repair, operative techniques, materials used, patient acceptability and expected longevity of the repair procedure.

Article Synopsis
  • The study assessed the risk of tooth fractures and crack progression over three years in patients with cracked posterior teeth.
  • Two hundred and nine dentists participated, observing 2,601 patients, and data was collected on patient, tooth, and crack characteristics during annual follow-ups.
  • Findings revealed that only 3.0% of cracked teeth fractured and 12.3% of untreated cracks progressed, with specific tooth and patient characteristics influencing these outcomes, but no overlap in factors linked to fractures and crack progression.

Background: An important step in integrating dental and medical care is improving understanding of the frequency and characteristics of dental practitioners who conduct health risk assessments (HRAs).

Methods: From September 2017 through July 2018, active dentist and hygienist members of the South Atlantic region of The National Dental Practice-Based Research Network (N = 870) were invited to participate in a survey evaluating their HRA practices (screening, measuring, discussing, referring patients) for 6 health conditions (obesity, hypertension, sexual activities, diabetes, alcohol use, tobacco use). For each health condition, the authors used ordinal logistic regression to measure the associations among the practitioner's HRA practices and the practitioner's characteristics, barriers, and practice characteristics.

Data on dental practices related to caries risk assessment (CRA) are scarce among Brazilian dentists. This study aimed to determine the prevalence of CRA use by dentists and factors associated with its use, as well as to quantify dentists' ratings of the importance of specific factors when treatment planning. Dentists registered at the Regional Council of Dentistry of São Paulo State - Araraquara region were sent two paper questionnaires that comprised: a) characteristics of dentists themselves, their practices, and their patients; and b) the translated version of the "Assessment of Caries Diagnosis and Caries Treatment" Questionnaire from the U.

Purpose: To 1) quantify practitioner activities of the National Dental Practice-Based Research Network (Network) for which Continuing Education (CE) credits were received (study training, videos, webinars, meetings, and symposia); 2) quantify practitioner coauthoring Network publications and presentations; and 3) test whether practitioner characteristics were associated with participation in these activities.

Methods: A retrospective analysis of 4361 practitioners who enrolled in the Network between April 12, 2012 and October 12, 2018.

Results: Overall, 59% (n = 2586) of practitioners earned CE credit from the Network; among these, 68% (n = 1757) from a video, 38% (n = 993) attended an annual Network meeting, 31% (n = 798) due to training for a Network clinical study, 9% (n = 226) attended a national symposium, and 7% (n = 170) participated in a Network webinar.

Objectives: This study aimed to 1) quantify the evidence-practice gap (EPG) between dental clinical practice and published evidence on Minimal Intervention Dentistry (MID) among dentists in Japan; and 2) examine the hypothesis that dentist characteristics have a significant association with the EPG.

Methods: We conducted a cross-sectional study via use of a web-based questionnaire survey of dentists who were affiliated with the Dental Practice-based Research Network Japan (n = 297). To quantify the EPG on MID, we used a questionnaire that included 10 clinical questions or scenarios to assess concordance between dental practice and published evidence on MID.

Objectives: The study objective was to: (1) quantify symptom (pain) and crack changes during one year of follow-up, among teeth that had at least one visible crack at baseline but which did not receive treatment for those cracks; (2) identify any patient traits/behaviors and external tooth/crack characteristics correlated with these changes.

Methods: In this observational study, 209 National Dental Practice-Based Research Network dentists enrolled a convenience sample of 2858 subjects, each with a single, vital posterior tooth with at least one observed external crack; 1850 teeth remained untreated after one year of follow-up and were the cohort for analyses. Data were collected at the patient-, tooth-, and crack-level at baseline, one-year follow up (Y1), and interim visits.
