| Popis: | Objective: To discuss possible relationships between class III malocclusion and perioral forces by measuring the pressure from the lips and the tongue of children with class III malocclusion. Methods: Thirty-one children with class III malocclusion were investigated and their perioral forces were measured at rest and during swallowing under natural head position by a custom-made miniperioral force computer measuring system. Results: The resting pressures exerted on the labial side and palatine side of the upper left incisor, as well as the labial side and lingual side of the lower left incisor, were 0 g/cm2, 0 g/cm2, 0.57 g/cm2 and 0.23 g/cm2, respectively. Correspondingly, the swallowing forces were 2.87 g/cm2, 5.97 g/cm2, 4.09 g/cm2 and 7.89 g/cm2, respectively. No statistical difference between muscular pressure and gender existed. During swallowing, the lingual forces were significantly higher than the labial forces (P |
