概要	Enamel pearls are sometimes seen on the root surfaces of molar teeth. Although this abnormality is realtively common,the histological and radiological characteristics of enamel pearls have not been studied in detail. T herefore, we used micro-computed tomography to study extracted teeth bearing enamel pearls on their root surfaces,with particular focus on the mineral density of the enamel in these pearls. We conclude that this type of mineral denstiy analysis may be useful in studying the etiology of tooth malformations,and the micro-CT is useful for measuring mineral denstiy in small tooth structures.
