The aim of this study is to the evaluate the stability of the amount of healthy tooth structure exposed after laser versus conventional technique of fiberotomy during orthodontic extrusion.
Parallel groups, two arm, superiority Randomized Controlled Clinical Trial, with 1:1 allocation.
PICO:
Population: patients with endodontically treated teeth and short clinical crown that require crown lengthening in the esthetic zone Intervention: laser fiberotomy with orthodontic extrusion Control: conventional fiberotomy using blade with orthodontic extrusion
Outcomes:
Primary outcome: Stability of the mount of healthy tooth structure exposed.
Secondary outcomes:

| conventional circumferential supracrestal fiberotomy | Procedure | The amount of tooth that need to be extruded will be measured Bonding brackets slot 0,022"x0.028" Roth prescription on piggyback for the tooth with (0.016". x 0.022 ") stainless steel main arch wire and 0.0014" nickel titanium auxiliary. • Fiberotomy After 2 days of bonding, local anaesthetic solution will be administrated. The depth of the fibrotomy should be equal to the amount of tooth that need to be extruded. supracrustal fibrotomy will be performed using 15 c blade (Carvalho, Bauer et al. 2006) |
| Measure | Description | Time Frame |
|---|---|---|
| Stability of amount of healthy tooth structure exposed | Amount of healthy tooth structure exposed: This is measured from the 6 guide marks in the acrylic stent around the extruded teeth to the healthy tooth structure using UNC periodontal probe in millimeters. | 8 weeks after retention. |
| Measure | Description | Time Frame |
|---|---|---|
| Stability of gingival Margin | This is measured from the 6 guide marks in the acrylic stent around the extruded teeth to the gingival margin using UNC periodontal probe in millimeters. | 8 weeks after retention. |
| Stability of the alveolar bone |

| laser circumferential supracrestal fiberotomy | Procedure |
|
|
This is measured from the 6 guide marks in the acrylic stent around the extruded teeth to the top of the alveolar crest using UNC periodontal probe in millimeters.
This is done after administration of local anesthesia by infiltration around the tooth
| 8 weeks after retention. |
| Rate of tooth extrusion | This is measured by calculating the average tooth extrusion per week by dividing the amount of healthy tooth structure exposed on the number of weeks. | 8 weeks after retention. |
| Sulcus depth | The distance from gingival margin to the base of the sulcus in millimetres. | 8 weeks after retention. |
| Post operative pain | VAS scale | 8 weeks after retention. |
