TUESDAY, June 12, 2012 (MedPage Today) — Poor oral hygiene may be associated with increased risk of cancer and premature death, researchers found.
Among healthy adults in Sweden plaque build-up increased the relative risk of premature death 79 percent, Birgitta Söder, PhD, of the Karolinska Institutet in Huddinge, Sweden, and colleagues reported in BMJ Open.
The finding, the authors wrote, suggests that increased plaque and associated toxins and enzymes, may be released from the built-up biofilm and enter the bloodstream through the gingival crevice, thus increasing the risk of malignancies.
In 1985 Söder and colleagues initiated a longitudinal study of 1,390 randomly selected, healthy Swedish adults ages 30 to 40, who had no signs of periodontitis at baseline. The participants were followed with periodic checkups including smoking habits and oral health through 2009.
Dental plaque measures were taken at baseline and in 1996, 1998, 2000, 2001, and 2009.

Over the 24-year study period, 58 patients died, including 35 deaths due to malignancies.
Individuals still alive at the end of follow-up had a significantly lower dental plaque index than those who died.
After multiple logistic regression analysis, Söder and colleagues found age, male gender, as well as the amount of dental plaque were principal independent predictors of mortality at follow-up. Age and male gender almost doubled the risk of dying prematurely.
They added that there were statistically significant differences between dead and living patients "regarding the amount of dental plaque, gingival inflammation, and dental calculus, indicating a significantly poorer dental status in the subjects who died when compared with survivors."
Söder and co-authors said their hypothesis will require additional studies to determine whether any causal relationship can be derived from the association between poor oral hygiene and cancer mortality.
Reading Michael Bloomberg’s latest editorial regarding his tips for success got me thinking about all the lessons I’ve learned in the past 18 years as a practicing dental hygienist. As an educator I have the privilege of passing these lessons along to all the students entrusted to my care. Some pay attention and listen. Others… not so much. Declaring myself an expert on all things dental hygiene (*chuckle*) or, at the very least, a successful dental hygienist, I offer these tips to you, the future of my profession, in no particular order:
1. Keep your private business off The Facebook and The Twitter, et al No one enjoys The Facebook more than I, with all its socializing and picture gazing, but there is a price to pay. Be very careful about the information and images you share, because the world is a small place and there is no shortage of people, “friends” and otherwise, who are watching and judging you. It is human nature. Your image – your reputation – is more valuable than gold. Respect it.
2. Continue your education The practice of dental hygiene is at a very exciting time. Your professional organization, ADHA, is working diligently every day across the nation to expand the duties you are permitted to perform. These expanded functions, however, will only be performed by hygienists who are properly educated. Do not become complacent. Get your local anesthesia certification. Get a bachelor’s degree, if you only have an associate’s degree. Get a master’s degree if you have a bachelor’s degree. There are many programs and institutions to choose from – and a plethora of delivery methods. Don’t hesitate. Go now!
3. VOLUNTEER Your skills and education are needed everywhere by everyone. There are many organizations that run programs abroad in countries across the world in every continent. These programs require a commitment of time and money, though. If that’s too much, then look in your own communities. Organize a charitable event, participate in a health fair, volunteer to perform an oral health presentation at your children’s school, convince your boss to do a “public health day,” etc. I traveled to the Dominican Republic last year with Somos Amigos Medical/Dental Missions. This year participated in the Missions of Mercy event at the ADA convention in New Orleans. The people who participate in these events are inspirational, the people you treat are grateful. The return on this investment? Pride in humanity. Priceless.
4. Stay connected When I graduated from hygiene school, I was focused on finding work. Staying connected to my alma mater and my hygiene school friends was not on my list of priorities. I regretted that years later when, working through a divorce, I realized I needed to support myself and my children. The prospect of working full time in one office was not appealing to me at all. So I had to form new professional relationships and do a lot of research about colleges. It was a very difficult time, personally, and not the best time to explore new employment possibilities. I will always be grateful to those friends and colleagues who helped me get through that time. I now devote time to maintaining those relationships and cultivating new ones.
5. Stick to your guns I graduated hygiene school in 1995 and one thing has remained unchanged since then: too many in and outside of the field are not aware of how much dental hygienists know. Dentists, dental students, receptionists, office managers, patients – too many! It now becomes your responsibility to educate them. Do not be disturbed or discouraged by this; they do not mean to offend. They do not know part of our coursework included histology and embryology, microbiology, human anatomy I and II, oral pathology, and organic chemistry (the course that brought me great misery), nor that we can identify all the parts of a cathode and anode, know the active ingredients in every mouth rinse in existence, and know the qualifying criteria for the patients in the NERB exam. How could they? Could anyone ever dream of such a thing?! Be patient with them, show them what you know, and don’t back down if you know you’re right.
6. Be humble and gracious Sometimes I see new graduates complain about their working environments. I guess it comes from the trauma of surviving hygiene school. Anyone who passes hygiene school and the licensing exams necessary to become a registered dental hygienist is both smart and tough. But there is a lot to be said for experience. While I received a quality education at New York City College of Technology, a great deal of what I know I learned from others – dentists, dental hygienists, and dental assistants. I thank them all for taking the time to show me how to pour impressions, take a PA freehand, diagnose decay around the margin of a crown, recognize a cracked tooth, and how to properly scale and root plane. You all made me what I am, and I am grateful.

As easy as it is to renew a license, half of dental hygienists view the process as being a “rubber stamp” rather than “ensuring updated skills and competence among dental professionals,” according to a survey conducted by RDH eVillage in May 2015.
