REVIEW OF THE LITERATURE: LOW LEVEL
LASER THERAPY IN THE TREATMENT OF
TEMPOROMANDIBULAR DISORDERS
Hadi Daia, Heidi C. Crow, Thomas S. Mang
Buffalo, NY
Background: Low level laser therapy (LLLT) has been used for
over two decades in the treatment of temporomandibular
disorders (TMD). This review of the literature evaluates the
current evidence for the use of LLLT as a treatment modality in
treating patients with TMD.
Study: The literature was searched for published clinical
trials or retrospective studies including participants with
one or more TMD diagnoses, and using LLLT in the treatment.
Twenty studies were identified, 2 retrospective studies
and 17 clinical trials. These studies were evaluated and
discussed.
Results: All retrospective studies and 9 out of the 17 clinical trials
had positive results. Studies with negative results are most likely
due to insufficient dosing or improper design.
Conclusion: LLLT can be considered as an alternative physical
medicine modality in treating patients with TMD. State of the art
dosing is suggested. More studies are needed to define the
ultimate dose specific to each TMD condition.

PORT WINE STAINS PREVIOUSLY TREATED
WITH AN INTENSE PULSED LIGHT SYSTEM.
TREATMENT WITH A DUAL-WAVELENGTH
LASER SYSTEM (595, 1,064 NM) IN 40 PATIENTS

Madrid, Spain
Background: The elective treatment for port wine stain (PWS) is
considered the pulsed dye laser. Other light devices like intense
pulsed light (IPL) systems have shown efficacy in the treatment of
PWS. In our experience only about 25–30% of the PWS treated
with IPL achieved complete clearance. To understand the effect of
the dual PDL-Nd:YAG laser on resistant PWS, 40 patients
previously treated with an IPL system received additional
treatments with the dual laser.
Study: Forty patients 28 females and 12 males, average age of
35.5 years (14–72 years) previously treated by an IPL
(Photoderm-Vasculight, Lumenis, Yokneam, Israel) were enrolled
in a study to receive treatment with the and dual PDL-Nd:YAG
laser (Cynergy with Multiplex, Cynosure, Westford, MA, USA).
The recalcitrant PWS were located: 3 on the leg, 4 on the arm, 7 on
the trunk and 26 on the face. In two patients the PWS was
associated with Sturge–Weber syndrome and in three patients
with stable hypertrophy. In six patients a CO2 laser was used to
treat the nodules. Four patients received between 1 and 5 IPL
treatments, 10 patients received 5–10, 8 patients received 10–15
treatments and 18 patients received more than 15 treatments.
Patients were subsequently treated with the dual wavelength
laser using parameters in group IV, a 7 or 10 mm spot size, PDL
fluency between 7 and 11 and YAG fluency between 40 and 60.
Twenty patients received two treatments with the dual laser, 18
patients received three treatments and 2 patients received four
treatments.
Results: Improvement with IPL treatments were as follows: two
patients had no change. Fifteen patients improved 0–25%, 11
patients had 25–50% improvement, 11 patients had 50–75%
improvement and 1 patients had > 75% improvement. After dual
laser treatments, five patients (four with facial lesions), had no
improvement. Twenty-three patients improved between 25% and
50%; 10 subjects improved between 50% and 75% and 1 patient
achieved > 75% improvement. Ten of the 40 subjects indicated
that the dual laser was more painful and 20 patients felt
equivalent pain. Eight patients had edema and crusting, 5
patients experienced persistent erythema, 2 hypopigmentation, 6
patients had textural changes and one hypertrophic scar. The
percentage of secondary effects were a result of delivering high
fluencies on resistant PWS.
Conclusion: 87.5 of patients improved after dual laser
treatment. Of patients who had no response of dual laser
treatment 80% had lesions on the face. In summary, dual
treatment might be an option in treating PWS resistant to IPL
systems.

TREATMENT OF BECKERS NEVUS WITH
MODIFIED INTENSE PULSED LIGHT IN
INDIAN SKIN

Pune, India
Background: Few reports have been published about the
treatment of Becker’s Nevus using Er:YAG, Qs-Nd:YAG, LP Ruby
and intense pulsed light without impressive results. To evaluate
the efficacy and safety of modified IPL in the treatment of Becker’s
nevus in Fitzpatrick skin type IV and V.
Study: Nine patients (four male, five female), 13–29 years of age,
and of skin phototype IV and V were treated with modified IPL
(LEO 540 on Harmony platform, Alma Lasers) with 540 nm filter,
fluence energy of 16–20 J/cm 2 , pulse width of 10–12 milliseconds,
at 1–4 months intervals for 4–6 sittings. VAS scoring (VAS 1–4)
is done two blinded dermatologists for evaluation of pigment
lightening, color matching with surrounding skin and
complications. All the patients were followed for 6–18 (average 7)
months after the last treatment session.
Results: At end of four sessions mean pigment reduction was 2.9
on VAS of four while it was 3.8 at six sessions. Color match with
surrounding skin was observed excellent ( > 75%) in 4/9, good (50–
75%) in 4/9, fair (25–50%) in 1 patient. Clearance was better and
longer lasting at fluence 19–20 J/cm 2 than 16–18 J/cm 2 and better
at 10 milliseconds than 12 and 15 milliseconds. Transient
hypopigmentation, erythema and hyperpigmentation is observed
for a variable period of 4–12 weeks while no scarring is seen in
any patient.
Conclusion: LEO 540 at narrow pulse width and high fluence
is safe and effective treatment for Becker’s Nevus in Indian
skin.
