Know the Dental Secrets of Edo-era Japanese Bacterial Genomes


To examine relationships between the recognized micro organism and gum illness, researchers developed a brand new methodology to diagnose periodontal illness in historic skeletons.

Study first creator Takahiko Shiba explains, “Previously, teeth would need to be extracted from the jawbone to determine the root length and quantify bone loss as an indicator of gum disease. However, with advancements in micro-computed tomography technology, we were able to accurately quantify bone loss without removing teeth from the skeletons”.

Unexpectedly, researchers detected gum illness in 5 of the 12 Edo-era skeletons (42%), thus the prevalence of gum illness amongst people within the Edo period seems to have been much like that within the trendy period; 37.3% of Japanese folks of their forties had been discovered to undergo from gum illness in 2005.
