Evidence based Periodontology

Evidence-based dentistry (EBD) and periodontology emphasize integrating the best available scientific evidence with clinical expertise and patient preferences to improve oral health care. This approach bridges the gap between research and clinical practice through systematic reviews, critical appraisal of evidence, and structured decision-making. The document outlines the principles, development, steps, levels of evidence, and sources of EBD, contrasts evidence-based and traditional periodontology, and discusses its application in periodontal disease prevention, diagnosis, and management. Despite challenges such as information overload and barriers to implementation, EBD enhances quality of care, supports rational clinical decisions, and promotes continual updating of professional knowledge.
