Abstract
Eruption Sequestrum generally produces no symptoms, while it shows discomfort or pain during mastication in some cases, and then it will spontaneously fall off. We described the clinical and histopathological findings of eruption sequestrum appearing in the lower first molar region of 2 children, both 6-year-old boys. The patients complained of indefinite discomfort. Clinical examination showed fibrous binding of a part of a small hard tissue fragment to the gingiva. Histopathological examination of the small hard tissue revealed that osteocytes had disappeared from the bone lacunae, showing sequestrum. On the surface of the sequestrum, bacterial aggregation had been formed. Slight inflammation was observed in the gingiva around the sequestrum. Which seemed to be caused by difficulty in cleaning of the area of the fragment.
