Those with<unk>  would usually begin suffering painful toothaches and swelling of the gums. The pain was characterized as "persistent yet progressive ... spreading to neighboring teeth and<unk> bone". Over time, pus formation developed penetrating the oral mucosa with the formation of fistula, tooth loss, and recurrent abscesses. Further progression led to the formation of sequestrum (dead bone that has separated from living bone) after three months and necrosis of the<unk>  within six months. The distinguishing feature of this disease was the eventual separation of the sequestrum which was described as porous and light in weight. The lower<unk>  was more commonly affected than the upper<unk> . Affected bones glowed a greenish-white colour in the dark. The condition also affected the brain, provoking seizures in some chronic cases.
