Design outcomes
Primary
| Measure | Time frame |
|---|---|
| gingival margin changes at baseline and at 1 month, 3 months, 6 months, and 12 months following surgery compare gingival margin changes as measured by clinical periodontal probing and digital intraoral scanning | — |
Secondary
| Measure | Time frame |
|---|---|
| gingival margin changes at baseline and at 1 month, 3 months, 6 months, and 12 months following surgery evaluate the longitudinal changes in gingival margin position following esthetic crown lengthening surgery,levels of patient satisfaction, quality of life associated with esthetic crown lengthening surgery at baseline and at 3 months, 6 months, and 12 months following surgery Oral Health Impact Profile (OHIP-14), Patient satisfaction questionnaire,anticipated pain levels at 24 hours, 48 hours, and 1 week following surgery visual analog scale (VAS) for pain | — |
