Evaluating Laser and Piezocision vs. Piezocision Alone on Root Resorption and Gingival Health During Tooth Retraction

Syria66 participantsStarted 2023-05-06

Plain-language summary

This trial aims to determine whether using a special laser (low-level laser therapy, or LLLT) in combination with a minor surgical procedure (piezocision) can safely accelerate orthodontic treatment. We are looking at its effect on two main safety issues: root shortening (root resorption) and gum health. We will compare three groups of patients who have their front teeth pulled back: one group receives the surgery and the laser, one receives the surgery alone, and one receives standard braces. We will measure root length on X-rays and check gums at the start, before the retraction phase, and after all the space is closed.

Inclusion criteria

✓. Healthy patients aged 17-28 years.
✓. Diagnosed with a Class II division 1 malocclusion, indicated for extraction of the upper first premolars, with an overjet of 4-10 mm and a normal or increased facial height assessed clinically and cephalometrically using three angles (MM= 23ᵒ-33ᵒ, Jarabak Ratio ≤ 64%, and Y-axis angle= 66ᵒ-75ᵒ)
✓. A skeletal Class II relationship, confirmed by a cephalometric ANB angle between 4° and 7°
✓. An overbite of 0%-33%
✓. Good oral hygiene, defined by a probing depth of ≤3 mm and no radiographic evidence of alveolar bone loss
✓. Absence or a mild level of crowding
✓. A full complement of teeth, excluding third molars.

Exclusion criteria

✕. A history of previous orthodontic treatment
✕. Any systemic disease or medication known to interfere with orthodontic tooth movement.

What they're measuring

Change in external apical root resorption

Timeframe: (T1) one day before treatment commencement, (T2) at the end of the levelling stage (expected to occur within 3 - 4 months), (T3) one day after the end of retraction (expected to occur within 6 months).

Change in the Gingival Index

Change in the Dental Plaque Index

Change in the Bleeding Index

Change in Gingival Width
