Abstract: This invention concerns a system to update encoded data stored in a memory of a data processing device such as a smartcard. In this system, the data is represented by a tree structure in directories and files according to an object representation. According to the invention, the update system comprises a specific referencing object able to reference all or some of the attributes of the encoded data in memory. A microcontroller is then programmed to extract from the referencing object the information required to locate the memory block occupied by this attribute, and update this block, replacing it by the new previously encoded data.

Abstract: A dental instrument with interchangeable roller tips for distributing restorative materials on a tooth surface quickly, precisely and homogeneously with little adherence of the restorative material to the instrument. The instrument has an elongate body with a handle portion and one or two working ends extending therefrom with a roller tip rotatably mounted on each working end. The roller tip may be removable from the working end, such that differently shaped tips may be used interchangeably during the restoration of the tooth, as necessary. The roller tip may rotate directly about the working end, or alternatively, a bushing or bearing may be rotatably mounted on the working end between the working end and the roller tip, such that the roller tip is rotatable on the working end by means of the rotatable bushing or bearing.
