Study Notes

  • Evidence-based decision making in dentistry applies scientific literature to clinical practice, integrating research evidence, clinical expertise, and patient preferences for optimal care.

Applying Literature to Clinical Practice

  • Key aspects involve determining the validity and relevance of research results, presenting statistical information clearly, and understanding the clinical significance and practical translation of research findings.

Evidence Component

  • Practitioners should find relevant, up-to-date evidence, critically appraise it for validity, reliability, and usefulness using tools like CASP
  • Should understand study results and implications.

Patient Considerations

  • Practitioners consider patient preferences, specific conditions, dental goals, study population similarity, treatment qualification, affordability, whether treatment addresses the chief complaint (pain, swelling, food impaction, bleeding/sore gums, sensitivity, staining) and potential effects.

Clinical Expertise

  • Practitioner's expertise includes drawing on experience, applying judgment, understanding patient responses, and knowing when to seek guidance.

Outcome Assessment

  • Practitioners evaluate recommendation efficacy, determine success, identify failure reasons, consider modifications, and restart the process if needed.
  • The framework helps dental professionals make informed decisions by integrating evidence, expertise, and patient preferences, but burnout is a concern applying it consistently.

Understanding Appraisal

  • Critical appraisal is essential for providing evidence-based care, combining scientific evidence, clinician skills, and patient needs.
  • During appraisal, professionals determine author credibility, assess resource usefulness and validity, evaluate study quality, and identify strengths and weaknesses.

Key Evaluation Questions

  • Key questions to consider during appraisal, purpose, appropriate design, result validity, bias, balance, and relevance of studies.

Validity and Reliability Concepts

  • Validity measures how well a study evaluates its intention, including internal and external validity.

Internal Validity

  • Internal validity determines if outcomes are attributable to interventions, considering research design, sampling, protocol, data collection, and statistical analysis.

External Validity

  • External validity measures generalizability to the broader population, focusing on sample collection techniques.

Reliability

  • Reliability measures consistency of results, such as an explorer obtaining consistent pocket depths, highlighting it as reliable, even if not valid for the intended purpose.

Significance in Research

  • Statistical significance indicates the intervention effect wasn't by chance, using a p-level typically <0.05.
  • Rejection of the null hypothesis at p
