Randomized trial demonstrates a new micro-sampling method for various tissues, suggesting improved sampling techniques.
An attempt has been made to develop a technique for the serial sampling of porous enamel, mesenchymal tissues, ectopic mineral deposits, developing tissues and other material not amenable to the established technique of sampling by acid etching. The samples are removed by abrasion and the layer thickness of the samples measured using a Mikrokator. The determination of fluoride distribution across various tissues has been used to illustrate the scope of the method.
