Registered outcomes9
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | The primary outcome was clinical crown lengthening. | Baseline, 1 week, 3 months and 6 months post-operatively. | The primary outcome was crown lengthening confirmed by measuring the increase of the relative gingival margin (RGM) in mm from the incisal edge of the vacum stent to the gingival margin before and after the treatment modalities. |
| Secondary | Secondary outcome was comparing the morbidity of the open flap group to the minimally invasive flapless group | 24 hours and one week after the surgery. | Secondary outcome was comparing the morbidity of the open flap group to the minimally invasive flapless group, using visual analog scale (VAS score) ranging from 0 (no pain) to 10 (worst pain imaginable) at 24 hours and one week after the surgery. |
| Secondary | Bleeding on probing | Baseline, 1 week, 3 months and 6 months post-operatively. | Measurement of bleeding on probing using the Binary system: 0= no bleeding 1= bleeding on probing |
| Secondary | Gingival Index | Baseline, 1 week, 3 months and 6 months post-operatively. | Gingival index (GI): according to (Löe, 1967) index system Scores (0-3) 0= Normal gingiva Natural coral pink gingiva with no inflammation 1. Mild inflammation, Slight changes in color, slight edema. No bleeding in probing. 2. Moderate inflammation, Redness, Edema and glazing. Bleeding upon Probing 3. Severe inflammation, Marked redness and edema/ ulceration/ tendency to bleed spontaneously |
| Secondary | Plaque Index | Baseline, 1 week, 3 months and 6 months post-operatively. | using (Löe, 1967) index system, scores (0-3) 0= Absence of microbial plaque 1. Thin film of microbial plaque along the free gingival margin 2. Moderate accumulation of plaque in the sulcus 3. Large amount of plaque in the sulcus or pocket along the free gingival margin |
| Secondary | Clinical attachment level (CAL) | Baseline, 1 week, 3 months and 6 months post-operatively. | Clinical attachment level (CAL) was measured in mm from the cemento enamel junction to the base of the gingival sulcus following the marked grooves. |
| Secondary | Pocket depth (PD) | Baseline, 1 week, 3 months and 6 months post-operatively. | Pocket depth (PD) was measured in mm from the gingival margin to the base of the gingival sulcus following the marked grooves |
| Secondary | Width of keratinized tissue (WKT) | Baseline, 1 week, 3 months and 6 months post-operatively. | Width of keratinized tissue (WKT) was measured in mm from the free gingival margin to the muco-gingival line following the marked grooves |
| Secondary | Relative bone level (RBL) | preoperative and immediately post-operative. | Relative bone level (RBL) was measured in mm from the incisal end of the vacuum stent to the bone crest, guided by the fixed grooves. And was recorded preoperative and immediately after the surgery by bone sounding technique. |
