Gummy smile caused by a short or hyperactive upper lip Oral Health
Conditions
Interventions
The study is designed to evaluate the effectiveness of the conventional surgical lip repositioning (the removal of a partial thickness flap) with a surgical scalpel compared to a carbon dioxide laser

Eligibility
Sex/Gender
All
Inclusion criteria
Inclusion criteria: 1. 4-6 mm of gum showing when smiling 2. Aged between 18 to 35 years old 3. The gummy smile is caused by soft tissue disorders only (shortness of the upper lip - hyperactivity of the muscles that lift it) 4. Healthy patients or those with controlled systemic diseases that do not prevent them from undergoing a surgical procedure 5. Good gingival and periodontal health
Exclusion criteria
Exclusion criteria: 1. Smoking 2. Pregnancy 3. Breastfeeding 4. A gummy smile of more than 6 mm of gum showing when smiling 5. Attached gingiva of less than 3 mm thick, which makes slide design and stability difficult
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Pain measured using a visual analogue scale (VAS) on the first day post-surgery 2. Edema measured using a VAS; the number 0 indicates the absence and the number 1 indicates the presence of edema on the third day post-surgery | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. The amount of gingival coverage after completion of treatment and the stability of the results measured from the edge of the lower lip to the midpoint of the gingival margin in each tooth in the smile position in mm before surgery and after 1,3, and 6 months 2. Patient satisfaction measured using a scale after 6 months post-surgery 3. The following clinical changes in the dimensions of the upper lip are measured using a millimeter scale ruler, specially designed to conduct research and hollowed out at the upper lip frenum after delineating the solar images in the lateral position at the first session before surgery and 1,3, and 6 months post-surgery: the external length of the upper lip from the base of the nose to the lower edge of the upper lip; the internal length of the upper lip; the length of the oral philtrum measured by placing the ruler on one of the sides of the oral philtrum and measuring the extension from the base of the nose to the upper edge of the upper lip; width of the red area of ??the upper lip from the upper edge to the lower edge of the upper lip; and, the amount of protrusion of the upper lip by measuring the distance between the upper lip and the nasolabial E-line (the line between the tip of the nose and the most prominent point on the soft tissues of the chin). 4. The following radiological measurements of the upper lip measured using cephalometric images before surgery and 6 months post-surgery: for upper lip thickness a horizontal line is drawn from the most prominent point of the upper lip towards the socket of the front teeth; the external length of the upper lip is measured from the base of the nose to the lower edge of the upper lip (interlabial cleft point); the internal length of the lip is measured from the deepest point in the groove of the upper lip to the edge of the incisive border of the teeth. | — |
