Referring Periodontal Patients: Clinical Decision Making by Dental and Dental Hygiene Students

Determinants of Clinical Decision Making under Uncertainty in Dentistry: A Scoping Review

Clinical decision-making for diagnosing and treating oral and dental diseases consolidates multiple sources of complex information, yet individual clinical judgements are often made intuitively on limited heuristics to simplify decision making, which may lead to errors harmful to patients. This study aimed at systematically evaluating dental practitioners' clinical decision-making processes during diagnosis and treatment planning under uncertainty. A scoping review was chosen as the optimal study design due to the heterogeneity and complexity of the topic. Key terms and a search strategy were defined, and the articles published in the repository of the National Library of Medicine (MEDLINE/PubMed) were searched, selected, and analysed in accordance with PRISMA-ScR guidelines. Of the 478 studies returned, 64 relevant articles were included in the qualitative synthesis. Studies that were included were based in 27 countries, with the majority from the UK and USA. Articles were dated from 1991 to 2022, with all being observational studies except four, which were experimental studies. Six major recurring themes were identified: clinical factors, clinical experience, patient preferences and perceptions, heuristics and biases, artificial intelligence and informatics, and existing guidelines. These results suggest that inconsistency in treatment recommendations is a real possibility and despite great advancements in dental science, evidence-based practice is but one of a multitude of complex determinants driving clinical decision making in dentistry. In conclusion, clinical decisions, particularly those made individually by a dental practitioner, are potentially prone to sub-optimal treatment and poorer patient outcomes.

Dental Students’ Knowledge, Confidence, Ability, and Self-Reported Difficulties in Periodontal Education: A Mixed Method Pilot Study

Evidence on periodontal education areas in which students have difficulties and their factors are limited. In this study, third- and fourth-year dental students’ knowledge was assessed as well as their confidence and ability in five periodontal educational areas using a mixed-method approach. A survey was used to collect data related to history-taking, medical examination, diagnosis, treatment planning, and follow-up. Student answers were compared to the consensual answers of an expert panel using the cosine-similarity index (CSI). Descriptive statistics assessed confidence and ability for diagnosis. Semi-structured individual interviews were used to collect data on reported reasons for difficulties in periodontal education. A content analysis was employed to analyze the interview data. Eighteen third- and fourth-year dental students completed the survey and eleven were interviewed. Students’ knowledge was adequate regarding diagnosis and treatment planning. Third-year students’ median CSI were 0.93 and 0.89, respectively. Fourth-year students’ median CSI were 0.9 and 0.93, respectively. Students felt confident in history-taking and examination but lacked confidence and ability in diagnosis and treatment planning. Reported reasons for difficulties in periodontal education were linked to both preclinical and clinical pedagogical issues. Further improvements in preclinical and clinical periodontal education are needed to address students’ lack of knowledge, confidence, and skills in key periodontal areas.

Service-Learning in undergraduate dental education: Professional competence for clinical decision-making

OBJECTIVES

The objective of the present study was to evaluate a Service-Learning activity in a dental education programme and the clinical decision-making in the development of professional competence of undergraduate dental students.

METHODS

The study consisted of a single holistic case study that involved quantitative and qualitative analyses. A total of 246 last-semester students from a School of Dentistry in southern Brazil, between the years of 2013 and 2016, answered an anonymous online questionnaire with open- and closed-ended questions (5-point Likert scale). Two thematic axes were analysed: structural and pedagogical evaluation of the internship experience and development of professional competences (theory of Ergology). The SPSS program (16.0) was used to obtain means and standard deviations for a descriptive analysis of the data. Content analysis was performed for the qualitative data.

RESULTS

The scores ranged from neutral to positive concerning pedagogical dynamics (mean scores between 3.08 and 3.82). The preceptors were evaluated with the best mean score (3.82). All the components used to assess professional competences obtained positive scores with the exception of teamwork (2.95). Adaptations to the clinical protocols learned in class were made by 44% of the students.

CONCLUSIONS

The data showed that undergraduate dental students in the Service-Learning programme acquire competencies for clinical decision-making under unusual reality conditions. Adaptation of protocols was not related to less or greater knowledge of the protocols, which would be a negative condition, but to the students' ability to formulate connections between scientific knowledge and the clinical practice.
