Effect of Low Level Laser on Orthodontic Canine Retraction

NCT04381442 | Completed

• 1 other identifier: Laser Effect Canine Movement
• Study Type: interventional
• Target: 15
• Locations: 0 countries
• Sites: N/A

Brief Summary

The aim of this study was to determine whether orthodontically moved maxillary canines exposed to two different protocols and dosage of LLLT exhibited differences in amount and rate of orthodontic tooth movement.

Conditions

Dental Malocclusion

Keywords

Low Level Laser Therapy; Orthodontic Tooth movement; Canine Retraction; Two Protocols and Energy Doses

Outcome Measures

Primary Outcomes (1)

• Evaluation the rate of maxillary canine retraction

  Evaluation and comparison of amount and monthly rate of distal movement of maxillary canine, in both groups, that were determined by direct intraoral measurements and indirect measurements of 3D scanned study models

  6 Months

Secondary Outcomes (1)

• Evaluation of anchorage loss

  6 Months

Study Arms (2)

Buccal &palatal low level laser therapy

EXPERIMENTAL

In group I,low level laser therapy was delivered at 10 points; 5 from buccal and 5 from palatal aspects with a total dose of 8 Joule (J) per session that distributed as follows; 2 cervical, 1 middle, 2 apical. Maxillary canines were irradiated with a gallium aluminum-arsenide diode laser in continuous mode with 635 nm, 100 mW, 25 J/cm2, 8 seconds/ point, 0.8 J/point.Maxillary canines were distalized by a standard protocol with uniform 150 gm retraction force via a nickel-titanium closed coil spring.Laser regimen was applied on days 0, 3, 7, and 14 in the 1st month, and thereafter on every 15th day until 6-month observation period of canine retraction phase.

Buccal low level laser therapy

ACTIVE COMPARATOR

In group II, low level laser therapy was delivered at 5 points; from buccal palatal aspects only with a total dose of 4 Joule (J) per session that distributed as follows; 2 cervical, 1 middle, 2 apical. Maxillary canines were irradiated with a gallium aluminum-arsenide diode laser in continuous mode with 635 nm, 100 mW, 25 J/cm2, 8 seconds/ point, 0.8 J/point.Maxillary canines were distalized by a standard protocol with uniform 150 gm retraction force via a nickel-titanium closed coil spring.Laser regimen was applied on days 0, 3, 7, and 14 in the 1st month, and thereafter on every 15th day until 6-month observation period of canine retraction phase.

Eligibility Criteria

• Age: 15 Years - 25 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17), Adult (18-64)

You may qualify if:

• Complete permanent dentition (3rd molars excluded).
• The age was ranged from 15 -25 years.
• Malocclusion that required extraction of at least maxillary first premolars, followed by canine retraction.
• Good oral hygiene and periodontal health.

You may not qualify if:

• Patients who diagnosed to have an indication for non-extraction approach.
• Serious systemic diseases and/or long term medications that could interfere with OTM.
• Previous orthodontic treatment.
• Poor oral hygiene or periodontally compromised patients.
• Craniofacial anomalies or history of parafunctional habits.
