Could the pulp be preserved in tooth with root resorption caused by embedded tooth?

Journal of Dental Sciences, 2023
At present, there are no recognized guidelines or consensus for the treatment strategy of the asymptomatic tooth with external root resorption caused by an embedded tooth (et-ERR). Most clinicians would like prophylactic or concomitant root canal therapy (RCT) along with the extraction of the embedded tooth.

A sweet tooth as the root cause of cardiac arrest [PDF]

Canadian Journal of Cardiology, 2009
A 71-year-old woman was admitted with hypotension and bradycardia. An electrocardiogram showed flattened T waves and increased U wave prominence, resulting in a long QT(U) syndrome. Her initial serum potassium level was 1.6 mmol/L (all other electrolytes, including magnesium, were normal).
