title: An improved abrasive enamel microsampling device.
abstract: An improved enamel abrasive microsampling technique with an electronic preset counter and comparator has been designed. In vivo enamel microsamples were obtained from 30 incisors and premolars. The results showed low coefficients of variations for both enamel fluoride concentrations and depths of microsamples in vivo.
