title: Lip function: a study of normal lip parameters.
abstract: This paper presents a study of normal lip parameters in 500 individuals representing both sexes and all age groups. The parameters studied were intercommissural distance at rest and during activity, soft-tissue gape, oral access, elasticity of perioral tissues, and upper and lower sulcus depths as an indication of lip curtain height. The strength of the orbicularis oris was measured using the pommeter (Peri-Oral-Muscle-Meter). Lip sensation was studied by testing two-point discrimination in all four lip quadrants. Statistical analysis revealed results to be significant to a p value of 0.01.
