Abstract:
Objective: To obtain the parameters related to the width of periodontal membrane from tooth mobility signal. Methods: Signals elicited from a tooth model of human maxillary central incisor, periodontal membrane made of silicone rubber and alveolar bone made of resin,were processed utilizing FX-1 tooth mobility measurement system. Results: R value of wave range,slope K and time parameter t2 in the tooth mobility signals were reduced with the increase of the width of periodontal membrane; time parameter t1 was increased with the increase of the width of periodotal membrane;R value and time parameter t2 were negatively correlated. Conclusion: R value and t2 may be the paticular indications reflecting the changing of width of periodontal membrane.
