1 A portable multi-channel instrument is developed for measuring perioral force, which is based on micro electronic technology and automatic control techniques.

2 Fig 3 - 18 Importance of the perioral musculature. Note the marked labiomental groove.

3 Perioral muscle pressure is a kind of force acting on dental arch from surrounding soft tissues, such as lip, cheek, tongue, and muscles.

4 In nonsmokers, creases around the mouth, or "perioral rhytids, " usually arrive with advanced age.

5 Methods:106 patients with perioral dermatitis were enrolled in the study. 89 cases infected with HP were divided into two groups.

6 AIM: To study the changes of perioral muscle pressure in the patients with skeletal crossbite before and after orthodontic and surgical treatment.

7 Methods Since 2002, 15 perioral scar patients have been operated on for the repair by using"free skin grafting, transferring of local skin flap,[] transferring of distant tubed flap".

8 After 30 days, the mean in the periorbital wrinkle score decreased by 9%, whereas the mean in the perioral wrinkle score decreased by 8%.

9 Objective: To summarize experiences of nursing care of malignant brain neurogliocytoma patients undergoing perioral temozolomide as chemotherapy.

10 Objective To generalize a better repair from the experiences on the repair of perioral scar contracture-caused deformities.

11 Objective:To study the relationship between helicobacter pylori(HP) infection and perioral dermatitis.

12 The wrinkle scores further improved after 60 days; the periorbital wrinkles decreased by 17% and the perioral wrinkles by 13%.
