Severe gum disease known as periodontitis can lead to tooth loss, and
treating it remains a challenge. But new approaches involving
silicon nitride,
a ceramic material used in spinal implants, could be on the way. The
surface of silicon nitride has a lethal effect on the bacteria that
commonly cause periodontitis. Now scientists, reporting in ACS' journal
Langmuir, are examining why this happens. Their findings could help
inform future efforts to treat the disease.
