Secondhand Smoke Proves to Be No "Joke" on Oral Health

Secondhand smoke may be associated with bone loss in subjects with periodontitis

A study published in this month's issue of the Journal of
Periodontology found that subjects with periodontitis who were
exposed to secondhand smoke were more likely to develop bone loss,
the number one cause of tooth loss.


Researchers studied rats that were induced with periodontal
disease. One group was not exposed to cigarette smoke while the
other two groups were exposed to either 30 days of smoke inhalation
produced by non-light cigarettes (cigarettes containing higher tar,
nicotine and carbon monoxide levels) or light cigarettes
(cigarettes containing lower tar, nicotine and carbon monoxide
levels). Results showed that bone loss was greater in the subjects
exposed to secondhand smoke regardless of if it was smoke from
light or non-light cigarettes than those who were exposed to no
smoke at all.


"Previous clinical research has proven a strong positive
correlation between smoking and gum disease. However, this study is
unique in that it evaluated the impact of secondhand smoke on
periodontitis," explained study author Getulio da R. Nogueira- Filho, DDS.


"This study really drives home the fact that even if you don't
smoke the effects of secondhand smoke can be devastating. Part of
maintaining a healthy lifestyle should include avoiding smoke
filled places such as nightclubs, bars and even some restaurants,"
said Preston D. Miller, Jr., DDS and AAP president. "The Academy
applauds the cities that are taking steps to make their hospitality
industries smoke free so all patrons can enjoy not only a good time
but also good overall health."
