Study of mandibular movements during speech.
We recorded the mandibular movements produced during the reading of a text, in Spanish, using a kinesiograph in a random sample of 71 people aged 24 to 35. In each recording we measured nine variables and did a descriptive analysis of each variable. Our findings support that the mandibular movement during speech has some definite characteristics. The most important fact is that it could be a high percentage of occlusal contacts at incisal level during speech. This has to be taken into account when exploring an occlusal trauma of unknown etiology.
