Is this trial a fit for you?

Likely a good fit

Adults 18–75 requiring a crown lengthening procedure in maxillary or mandibular teeth, without uncontrolled diabetes, smoking at or above 10 cigarettes/day, pregnancy, or other uncontrolled systemic conditions.

Probably not a fit

Patients with conditions that affect healing or those who do not respond to laser therapy may not see benefit.

What this trial studies

This interventional study compares a laser-assisted, flapless Er:YAG crown lengthening procedure with conventional surgical crown lengthening. It targets adults aged 18 to 75 who require crown lengthening in either jaw and excludes those with uncontrolled systemic conditions, heavy smoking, or other healing risks. Outcomes will focus on periodontal parameters after treatment to determine if the laser approach offers similar or improved results and recovery. The study takes place at Gulf Medical University in Ajman, led by a primary sponsor with no listed collaborators. The aim is to assess whether laser-assisted techniques can provide a less invasive option with comparable efficacy.

Why it matters

Potential benefit: If successful, patients could experience less invasiveness and comparable or improved periodontal outcomes with the laser approach.

How similar studies have gone: Laser-assisted crown lengthening has shown promise in some dental procedures, but direct, head-to-head data with conventional methods in this exact indication remain limited.
