Burton line
From Self-sufficiency
The Burton line is a clinical sign found in patients with lead poisoning. It is a thin, grey-blue line visible along the margin of the gums, at the base of the teeth.[1]
The sign was described in 1840 by Henry Burton:[2]
| “ | The edges of the gums attached to the necks of two or more teeth of either jaw, were distinctly bordered by a narrow leaden-blue line, about the one-twentieth part of an inch in width, whilst the substance of the gum apparently retained its ordinary colour and condition. | ” |
