Risk Assessment Models in Preventive Dentistry (Caries and Periodontal Disease): A Review

Background Preventive dentistry is shifting from a “one-size-fits-all” approach toward personalized care, driven by the recognition that individual risk factors dictate disease susceptibility. This review examines the evolution of risk assessment tools, transitioning from basic clinical observations to complex, multi-factorial analyses that include genetic, microbial, behavioral, and socioeconomic determinants.Method The article provides a critical evaluation of various risk assessment models specifically targeting dental caries and periodontal disease. It analyzes the predictive validity of these tools, their clinical utility, and the existing evidence regarding their implementation during routine dental visits.Results These models enable clinicians to move beyond reactive treatment by creating tailored prevention plans and specific interventions, which ultimately foster higher patient engagement. However, the review identifies several persistent barriers to widespread success, including a lack of universal standardization across tools, difficulties integrating complex models into routine clinical workflows, and the dynamic nature of risk factors, which change over time and require constant monitoring.Conclusion While risk assessment models are essential for optimizing oral health outcomes, their effectiveness depends on a clinician’s ability to apply them judiciously. To fully realize the potential of personalized preventive dentistry, future efforts must focus on standardizing these tools and accounting for the evolving health profiles of patients.Practical Implications For dental professionals, the shift toward risk-based care changes the ”chairside” approach from reactive to proactive. By identifying high-risk patients, clinicians can schedule more frequent recalls and apply intensive preventive therapies (like high-fluoride varnishes or antimicrobial treatments) where they are most needed.Risk models serve as a visual aid to help patients understand why certain treatments are recommended, improving treatment plan acceptance.Practitioners should view risk assessment as a continuous process rather than a one-time event, updating a patient’s profile as their lifestyle or health status changes.
