Tooth-Mobility-Tester

Tooth mobility and periodontal therapy.

Data collected as part of an 8-year longitudinal study on periodontal therapy involving 82 patients and 1974 teeth were analyzed to determine if tooth mobility influenced the result of treatment. For each patient, pocket depth, attachment level and tooth mobility were scored clinically at the initial appointment, and once a year for 8 years following periodontal therapy. The treatment consisted...

Development of a device to simulate tooth mobility.

OBJECTIVES The testing of new materials under simulation of oral conditions is essential in medicine. For simulation of fracture strength different simulation devices are used for test set-up. The results of these in vitro tests differ because there is no standardization of tooth mobility in simulation devices. The aim of this study is to develop a simulation device that depicts the tooth mobil...

Uw Vlsi Chip Tester

We present a design for a low-cost, functional VLSI chip tester. It is based on the Apple Macintosh II personal computer. It tests chips that have up to 128 pins. All pin drivers of the tester are bidirectional; each pin is programmed independently as an input or an output. The tester can test both static and dynamic chips. Rudimentary speed testing is provided. Chips are tested by executing C ...
