'Phossy jaw' is a condition that results from exposure to phosphorus, particularly white phosphorus. This condition is characterized by severe bone necrosis and can lead to the inflammation and destruction of the jawbone. Workers in industries that utilized phosphorus, such as match manufacturing or in certain chemical processes, were often at risk for developing this condition. The symptoms of phossy jaw often included pain, swelling, and advanced oral infections, leading to significant morbidity.

The historical context underscores the importance of understanding the health risks associated with chemical exposures and highlights the need for effective industrial hygiene practices to mitigate such risks.
