“…The LPs recorded in this study were higher in men than in women. This agrees with previous findings . Tsuga et al reported LPs of approximately 10 and 5 kPa in a group of male and female subjects, respectively, by using a balloon probe.…”

“…The last values lay approximately in the range recorded using the CS in our study. Ueki et al recorded a lip‐closing force of 12.7 ± 1.1 N in healthy adult women (age = 29.5 ± 4.9 years) and 15.0 ± 1.8 N in healthy adult men (age = 25.4 ± 7.9 years) by using a lip holder device (Lip De Cum, Cosmos Inst.

Objective To test a novel sensor for assessing lip function. Methods The electromyographic (EMG) activity of the upper orbicularis oris muscle (OOM), lip‐closing pressure (LP) and intraoral baro‐pressure (IP) were simultaneously recorded in 20 healthy subjects (10 women and 10 men) by using a novel composite sensor (CS). Subjects performed the lip‐closure, blow and suck tasks. EMG activity of the upper and lower OOMs was recorded using conventional surface electrodes to evaluate the accuracy of CS electrodes. The subjects also rated the user‐friendliness of the CS. Results Integrated EMG signals recorded using the CS and conventional electrodes from the upper OOM were highly correlated (r = 0.77 ± 0.12 in women and r = 0.81 ± 0.10 in men). The signal‐to‐noise ratio was higher with the CS than with the conventional electrodes. The mean LP during maximum lip closure, blowing and sucking ranged between 2 and 6 kPa in women and between 5 and 7 kPa in men. The corresponding IPs in women were 0.0 ± 0.5, 3.2 ± 1.4 and −4.4 ± 2.6 kPa, respectively, and in men were −0.5 ± 1.4, 4.9 ± 1.8 and −5.6 ± 2.8 kPa, respectively. All subjects rated the recording technique as excellent or good. Conclusion The CS was highly user‐friendly and accurate in recording the EMG activity of the OOM and could simultaneously measure the LP and IP. Therefore, it could be an effective tool for evaluating lip function.

Summary Background Tongue plays an important part in oral and maxillofacial system. Measurement of tongue pressure helps to evaluate the performance of tongue movement. Objectives To establish a system for measuring tongue pressure against hard palate and to preliminarily explore pressure distribution of individual normal occlusions and the relationship with dental arch form. Methods A total of 19 volunteers of individual normal occlusions out of 189 dental students met inclusion criteria (nine males, ten females, aged 25.53 ± 0.96 years). A force‐sensing resistor device was used to measure tongue pressure at rest and functional state (swallowing). We observed tongue pressure of four channel (anterior, posterior and lateral sides of hard palate) in sitting, supine position and swallowing. We analysed pressure differences according to gender and explored correlation relationship between tongue pressure and dental arch width and length using 3D digital maxillary image. Results In rest, tongue pressure against hard palate increased from front to back in both sitting and supine position, without gender differences. When swallowing saliva, the pressure at lateral sides of females was found significantly higher than that of males. Bivariate correlation analysis revealed duration of swallowing was positively correlated with BMI and weight at posterior region and positively correlated with palatal length at anterior palate. The greater the dental arch width, the smaller the pressure of swallowing in the anterior and lateral region. Conclusion In rest, there was consistent pressure of tongue against hard palate. The pressure increased significantly during swallowing, especially in females. Tongue pressure was related to dental arch length, width, BMI and weight.
