Variations over time in horizontal tooth mobility measured by an automatic diagnostic system

Abstract

We investigated variations over time in the viscoelastic properties of the periodontium of three men and five women. Horizontal (labio-lingual) tooth mobility of the maxillary central incisors was measured once each day between 11:30 am and 12:30 pm for 30 days in the men and for 50 days in the women, using an automatic diagnostic system. Basal body temperature was also recorded for the women. Horizontal tooth mobility was determined for three parameters related to viscosity and elasticity. We found variations over time in each of the parameters in both sexes. In addition, horizontal tooth mobility was greater during the luteum phase of the menstrual cycle than during the follicular phase.
