Do We Need a New Defi nition of Dentistry? David W. Chambers, EdM, MBA, PhD Every Saturday in America thousands of men buy three- eighth-inch drill bits. No one really wants a three-eighth- inch drill bit. Those who can help it avoid buying more than one. What we want is three-eighth-inch holes. The distinction is important. Customers want benefi ts, not features. Patients want oral health, not dentistry. The American Dental Association recently proposed a defi nition of oral health as “a functional, structural, aesthetic, physiologic and psychosocial state of well-being [which] is essential to an individual’s general health and .” The FDI World Dental Federation has just developed a defi nition as well: “Oral health is multifaceted and includes the ability to speak, smile, smell, taste, touch, chew, swallow and convey a range of emotions through facial expressions with confi dence and without pain, discomfort and disease of the craniofacial complex.” The nub: There is much to like in these defi nitions. They focus on the patient; they speak to a richer life for everyone. 1. Dentistry and oral health are not The expanded ADA and FDI defi nitions represent both the same thing. an opportunity and a liability. CBCT images open the prospect for dentists to treat obstructive apnea, but they 2.

At the least, involving dentists in “functional, structural, aesthetic, physiologic and psychosocial states” of patients will require collaborative working relationships with a very large number of sister professionals. At the worst, we can expect turf wars. Further, dentists may not want to assume complete responsibility even for traditional oral health care outcomes. Patients engage in inadequate home care, spotty follow up and damaging habits. Patients refuse optimal treatment plans and insurance companies may not pay for them. How can a dentist be held accountable for less than optimal oral health outcomes under such circumstances? There is a balance between opportunity and responsibility and between proper action and outcomes. ■

Prefabricated Blood Vessels May Revolutionize Root Canals While root canals are effective in saving a tooth that has become infected or decayed, this age-old procedure may cause teeth to become brittle and susceptible to fracture over time. Now researchers at Health and Science University in Research Leads to Treatment Portland, Oregon, have developed a process by which they can engineer new blood vessels in teeth, creating better long-term outcomes for patients and clinicians. for Rare Gum Disease Their findings were published online in June in Scientific Reports.

Consumption of Cannabis and Eff ects on Periodontal Oral Health

Suellan Go Yao, DMD, and James Burke Fine, DMD

ABSTRACT Cannabis plays a role in the legal, medical and dental fi elds. With more states passing medical marijuana laws, policymakers are concerned about possible cannabis use among nonpatients. Oral health effects include periodontitis, bone loss and gingival enlargement. Its Schedule I classifi cation makes it diffi cult to run randomized controlled studies on its effects. However, further medical study will allow for better policy concerning marijuana that may affect the population as a whole.

Oral Lichen Planus Flares Triggered by Cow’s Milk in a Patient With Elevated IgE Antibodies to Milk

Nita Chainani-Wu, DMD, MS, PhD; Anuradha Nayudu, BDS; and Daniel Purnell, BA, MPH

ABSTRACT A female patient with painful oral lichen planus that required daily topical corticosteroids completely eliminated cow’s milk/milk products (CMP) from her diet. Her oral discomfort improved about two months later and had mostly resolved by eight months. Blood tests showed an elevation of total immunoglobulin E (IgE) and CMP-specifi c IgE antibody titers. Over the next seven years, she was largely asymptomatic when continuing to avoid CMP, with the occasional inadvertent ingestion that resulted in fl ares.

Pre-Eruptive Resorption in a Patient With DiGeorge Syndrome

Tory Silvestrin, DDS, MSD, MSHPE; Nasser Said Al Naief, DDS, MS; Dezhi Wang, MD, HTL, QIHC; and Leif K. Bakland, DDS

ABSTRACT DiGeorge syndrome (DGS) is associated with defects of the palate, truncus arteriosus and tetralogy of Fallot, as well as cognitive defects and neuromuscular problems. Pre-eruptive resorption (PER) is a rare resorptive entity found within the dentin in the occlusal aspect of an unerupted tooth. A literature search could not identify any previous report on a patient diagnosed with both DGS and PER. This case report details a patient with concomitant DGS and PER.
