@entity1 @entity2522 @entity3384 @entity408
OBJECTIVES:     To evaluate age- and gender-related changes in the soft tissues, incisors, and @entity2522 during rest, speech, and posed @entity408 . MATERIALS AND METHODS:     A total of 265 @entity1 (122 @entity1 , 143 @entity1 ) ranging in age from 19 years to 60 years were recruited for this study. @entity1 were divided into one of the following four age groups: 19 to 24 years, 25 to 34 years, 35 to 44 years, and 45 to 60 years. Image capture was performed using standardized videographic methods. Each video produced pictures where measurements were performed: rest, speech, and @entity408 positions. RESULTS:     A statistically significant gender dimorphism was apparent in most of the variables. There was a significant @entity3384 and lip commissures height with aging and more markedly in @entity1 . A greater exposure of mandibular incisor with increasing age was a feature in both genders. With increasing age there was a significant decrease in maxillary incisor display, especially for @entity1 . CONCLUSIONS:     After 25 years of age there is significant difference in the aging process between @entity1 and @entity1 . Gingival and maxillary incisor display during speech and @entity408 is a youthful and feminine characteristic.
