Comparing laser and conventional techniques for tooth crown lengthening
Laser Verses Conventional Circumferential Supracrestal Fiberotomy in Orthodontic Extrusion for Crown Lengthening: A Randomized Controlled Clinical Trial
This study is testing whether using a laser or traditional method for lengthening tooth crowns works better for keeping teeth stable and reducing pain after treatment.

What this trial studies
This clinical trial evaluates the effectiveness of laser versus conventional circumferential supracrestal fiberotomy techniques in orthodontic extrusion for crown lengthening. It involves a randomized controlled design with two parallel groups, where one group receives laser treatment and the other conventional treatment. The primary focus is on the stability of healthy tooth structure exposure post-treatment, alongside secondary outcomes such as gingival margin stability and pain levels. Participants will be monitored for eight weeks following the procedure to assess these outcomes.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 to 50 with endodontically treated teeth in the esthetic zone that require crown lengthening.
Not a fit: Patients with poor oral hygiene, uncontrolled diabetes, or other specified exclusion criteria may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could improve the techniques used for crown lengthening, leading to better patient outcomes and enhanced aesthetic results.
How similar studies have performed: While there is limited data on the specific comparison of laser versus conventional fiberotomy techniques, similar studies in dental procedures have shown promising results with laser applications.
Eligibility criteria

Inclusion Criteria: * Age between 18 and 50 years old * Teeth in the esthetic zone * Restorable teeth with successful endodontic treatment * Adjacent teeth with clinical attachment of at least two-thirds of the root length, thus permitting adequate support for orthodontic movement * Crown root ratio after extrusion of the needed ferrule amount not less than 1:1 Exclusion Criteria: * Patients with bad oral hygiene or Periodontally affected teeth * Uncontrolled diabetic patients * Pregnant females * Medications that could affect tooth movement (bisphosphonate) radiation therapy less than 2 years * Moderate-to-heavy daily smokers (who report consuming at least 11 cigarettes/day) * Teeth with periapical inflammation, ankylosis or vertical root fracture * Teeth with probability of furcation exposure after extrusion. * The level of the root is 3 mm or more apical to the level of the bone
