What if the true measure of clinical success in dentistry was not how well we treat disease, but how effectively we prevent it from ever developing in the first place?
Penny Hatzimanolakis is a periodontist and prosthodontist who has been practicing evidence-informed, prevention-focused oral health care since 1994. A faculty member at the University of British Columbia's dental faculty since 2002, she is currently pursuing a doctorate in Educational Leadership. A published author, national speaker, and industry board advisor, she operates the Elevate Oral Health and Learning Centre, where she provides advanced training and individualized, patient-centred care with a strong commitment to serving underserved communities.
This episode applies the P4 medicine framework — predictive, preventive, personalized, and participatory — to oral health care, challenging dentistry's long-standing habit of measuring success by treatment volume rather than disease prevention. Penny introduces a compelling fifth P, preservation, as the overarching clinical goal that should unify all dental disciplines. The conversation spans periodontal risk management, individualized recall protocols, peri-implantitis prevention, and the role of emerging AI technologies in moving dentistry from reactive repair toward precision prevention.
Episode Highlights:
- Current dentistry measures success almost exclusively through treatment outcomes — restorations placed, pocket depths reduced, implants placed — while rarely quantifying how much disease was actually prevented. Reframing success to include avoided restorations, preserved attachment, and maintained healthy dentition would likely reveal that proactive prevention rates in most practices sit at only 10–15%, a standard no other medical discipline would accept.
- The standard twice-yearly dental recall interval has no scientific basis and originated largely from consumer advertising campaigns dating back to the 1920s and 1940s. Risk-based recall intervals — which may range from one to six months or beyond depending on the individual patient's disease activity, systemic health, and compliance — represent a more evidence-informed approach to maintenance scheduling.
- Guided biofilm therapy is an evidence-based, minimally invasive clinical protocol structured around a sequential eight-step framework that aligns directly with P4 medicine principles. The protocol incorporates disclosing agents to visualize biofilm, motivational interviewing, salivary diagnostics, nutritional counseling, and powered biofilm disruption using fine erythritol powder, allowing targeted management of biofilm as the primary etiological driver of both periodontal disease and peri-implantitis before a hand instrument is ever introduced.
- Patients with type 2 diabetes carry approximately a 50% elevated risk of developing peri-implantitis, and implant deterioration when it occurs progresses significantly faster than comparable breakdown around natural teeth due to the absence of a periodontal ligament and its associated host defense mechanisms. Thorough pre-implant risk stratification — including full medical history review, systemic disease assessment, and identification of compounding risk factors — is essential before implant placement is undertaken.
- Preservation of tooth structure is emerging as a unifying philosophy across dental specialties, exemplified in endodontics by the growing evidence base for vital pulp therapy including partial pulpotomy on mature teeth with carious pulp exposures. Using a calcium silicate-based hydraulic cement following incremental pulp tissue removal to achieve hemostasis can allow clinicians to avoid full pulpectomy and obturation, eliminating the associated costs of root canal treatment and the indirect restoration that typically follows.
Perfect for: general dentists, dental hygienists, periodontists, prosthodontists, and dental residents seeking to integrate evidence-informed prevention protocols, risk-based recall strategies, and minimally invasive principles into daily clinical practice.
If you have ever questioned whether dentistry's definition of success is truly serving your patients' long-term health, this conversation will change how you think about every patient you see.
