Abstract AR
الهدف من هذه الدراسة هو لتقييم و تحديد تغيرات ألشفه العليا في البعد الأفقي للوجه خلال كل من الاستراحة و الابتسامة.
شملت الدراسة ثلاثة و ثلاثين متطوع (15 رجال, 18 نساء) تتراوح أعمارهم بين 18 سنة و 23 سنة.
سجل لكل شخص 8 قياسات للشفة العليا خلال الاستراحة و خلال الابتسامة و أيضا شملت قياس طول القاطع المركزي العلوي، أظهرت النتائج بأن هناك فرق معنوي في أغلب القياسات بين الرجال و النساء فطول ألشفه العليا عند الاستراحة كان 1.8 ملم أقصر عند النساء من الرجال و كان طول القاطع المركزي حوالي 0.56 ملم أطول عند الرجال من النساء.
كانت الابتسامة المنخفضة هي السائدة بين النساء, و كانت الابتسامة المتوسطة أكثر شيوعا عند الرجال من النساء.
Abstract EN
Our objectives were to evaluate and quantify upper lip soft-tissue changes in the vertical dimensions both at rest and at maximum smile.
Methods thirty three volunteers (15 men, 18 women) aged 18 to 23 (mean, 21.5 years) were recruited for this study.
For each subject, 8 measurements of upper lip position and maxillary incisor crown height at rest and in maximum smile were recorded.
Results : A statistically significant sexual dimorphism was apparent in most of the measured variables.
Relaxed external upper lip length was 1.8 mm mm shorter in the women than in the men.
The mean maxillary central incisor length was 0.56 mm greater in the men than in the women.
A low smile line was more prevalent in the women, The average smile is more prevalent in male than female.
Conclusions : Data from this study clearly indicate sexual dimorphisms in upper lip length, maxillary incisor display, and resting external upper lip length.
Low smile patterns are more common among female patients, and also common among male patients while high smile are less common among female and male patients.
The average smile is more prevalent in male than female.
