Salivary Diagnostics: Your Molecular X-Ray

According to Merriam-Webster, one of the definitions of technology is a manner of accomplishing a task especially using technical processes, methods, or knowledge. This definition rings true for the introduction of clinical laboratory testing for the health care professions. It was noted in research by the NIH, “…it was not until 1896 that the first clinical laboratory was opened, a twelve-foot-by-twelve-foot room equipped at a cost of $50 at Johns Hopkins Hospital.”1 So for over a century, ...

My Visit to OralDNA® Labs

Have you ever wondered what happens to your patient’s saliva sample once it arrives at OralDNA® Labs?  Many PDS®-supported offices have been using OralDNA® Labs to analyze the saliva of their patients, relative to the patient’s periodontal infection.  This service gives them more information about the types and severity of a patient’s infection, which is the cause of periodontitis.  Additionally, however, it tells us something about the bacterial load and a patient’s inflammatory response, w...

Caries Risk Assessment Duo: The Canary System® and OraRisk® Caries

In the past, controlling or treating dental caries meant restoring all areas of decay. After which, the patient was believed to be “caries controlled” until something new developed.  We now know that this thinking is flawed.  Filling or restoring caries does not treat the disease, only its effects on the tooth.  In 2001, the National Institute of Health defined caries as a disease resulting in the destruction of tooth structure by acid forming bacteria found in dental plaque in the presence ...

OraRisk® Caries: Identifying Bacteria for Risk Assessment

Dental caries is defined as the progressive destruction of a tooth and is considered a major health issue in both adolescents and adults, in which reportedly 90% of the population is affected(1). Cavities are formed when acid erodes the hard tissues of the teeth (enamel, dentin and cementum). Acid is produced in the mouth when certain bacteria, such as Streptococcus mutans, ferment sugars into acid. For decades, S. mutans was believed to be the main bacteria involved in caries initiation ...

Life & Death and a Saliva Test

Sometimes I get so frustrated with the profession of dentistry. Here is my case in point: Five oral originating pathogens have been identified as causative in the development of atherosclerosis by the BaleDoneen™ peer reviewed study published in the British Medical Journal. Wait a minute, so they concluded that these oral bacteria are causative of atherosclerosis? Seriously? Yes!! And in the last one hundred years, atherosclerosis has killed more Americans than any other disease. Atheroscler...

Definition: Collecting a Salivary Diagnostic Specimen

According to an article written in the Journal of Clinical Microbiology, January 2009, “Saliva is a representative diagnostic specimen for an overall view of the oral microbiota, since bacteria from various sites and surfaces of the oral cavity are found in saliva and mouth rinses.”1 The OralDNA® salivary diagnostic collection is based on this principle, among several others, supporting saliva as a testing medium. Over the past decades, cumulative research has been instrumental in elevating ...

Definition: CLIA certified? CAP accredited? What does this mean?

In simple terms, being CLIA certified and CAP accredited ensures your test results are meeting and exceeding industry standards for clinical laboratory testing. The Clinical Laboratory Improvement Amendments of 1988 (CLIA) are federal regulations for United States based clinical laboratories to provide industry standards for testing of human samples for diagnostic purposes. These amendments were added to the laboratory requirements outlined in the Code of Federal Regulations, 42 CFR 493. ...

Case Study: Class II Periodontitis

Background: The patient is a 54 year old female who presented with the chief complaint “My gums bleed when I brush, there are possible cavities and I don’t like the tooth crowding.” Her last dental visit was about 6 years ago. There is a family history of diabetes, cardiovascular disease, stroke and cancer. The home care consisted of manual tooth brushing 1-2 times per day with occasional antibacterial mouth rinse. During the clinical assessment, it was discovered that several amalgam restor...

The True Cost of Clinical Lab Testing

As an in-office coach I often hear the following objection, “Clinical laboratory testing is too expensive. My patients won’t want to spend the money.” Taking into consideration the latest research, released in the online British Medical Journal November 29, 2016, which states that periodontal disease with high risk pathogens (Aa, Pg, Tf, Td, Fn) is causal for arterial sclerotic vascular disease, the patient can’t afford NOT to test for the presence of these dangerous bacteria. (1) As a pr...

What is “Differential Diagnosis”?

There is an old adage in medicine that says “When you hear hoof beats, think horses. Don’t think zebras.” This phrase can be applied to every patient and case; your eyes don’t tell the whole story. It is usually good advice to confirm the obvious, rather than spending time and resources investigating rare things. Consider the virtue of the “differential diagnosis”. In medicine, the differential diagnosis is a process by which the consideration of diagnosing one disease is distinguished fr...
