Dentistry in the Era of P4 Medicine

December 4, 2019

A decade ago, Leroy Hood proposed that medicine should move from reactive disease management to proactive care that is predictive, preventive, personalized and participatory.1 The tenets of this philosophy are now referred to as P4 Medicine. Combining technology, biology and a wellness approach, medicine is capable of providing care on a molecular, cellular and organ level to personalize each individual’s unique health experience. This information will make medical care radically more cost effective by personalizing care to each person’s unique biology and by treating the causes rather than the symptoms of disease. It will also create the environment for consumers to improve their heath as they make behavior and lifestyle changes. Working together, the health care system and patients should be able to reduce the incidence of complex chronic diseases. But this movement also comes at the risk of overutilization of technology and tests without a prior consideration of the patient’s individualized risk for a given disease. In addition to primary prevention, which involves measures to prevent a disease from occurring, and secondary prevention which attempts slow or reverse progression of a disease, and tertiary prevention which involves active treatment of the disease, P4 medicine now includes quarternary prevention, which considers patient risk and possible overtreatment.2  

In this changing model of medicine, how does this affect dentistry? The dental profession has traditionally been built on the surgical model of disease management.3 However, that model rapidly changing too. With the overdue recognition that the mouth is connected to the rest of the body, healthcare is starting to recognize that oral diseases have an impact on systemic health.4 Long gone are the days of scraping roots to treat periodontal disease, drilling holes in teeth to treat dental caries.

Just looking at dental caries risk management in light of the P4 medical model, this new approach includes care that is predictive, preventive, personalized and participatory. The surgical dental model fails on each point. The best practice of care for dental caries today is a risk management based philosophy. Caries risk assessment had been demonstrated to be predictive in clinical trials.5 It also focuses on preventive strategies, identifying risk factors and developing a regimen to prevent future disease.6 The prevention approach has a long history in dentistry. Today’s preventive dentistry should include not only primary, secondary and tertiary  prevention, but also quarternary prevention. Quarternary prevention strives to mitigate unnecessary or excessive intervention of the health care system while guidelines for non-surgical approaches are improving.

Caries risk management is also personalized as it identifies the specific risk factors contributing to an individual’s disease.7 This leads to a new conversation. Damaged teeth still need to be restored, but now professionals can discuss what’s causing the patient’s disease. The process then becomes participatory as the professional utilizes wellness coaching techniques to help the patient create personalized strategies for behavioral change to decrease specific caries risk factors.8

The new models of P4 Medicine and the Quarternary Prevention create new challenges but also new opportunities for the dental profession. As we continue to grow and change, new systems like Caries Risk Management allow us to create predictable and better outcomes for our patients in the 21st century, which has always been our goal.9
