LED phototherapy
significantly attenuates pain after insertion of
the elastic tooth separator and during other orthodontic procedures.
Recent advancements in dentistry are developing ways to
reduce chronic dental pain. One such approach is the LED phototherapy that
presents significant efficacy in pain management after the introduction of the
elastic tooth separators. The LED photography has a similar response but is
cost-effective as compared to laser lights. The study conducted after approval
of Institution Ethics Committee and evaluated the efficacy of IR LED
phototherapy (λ846 ± 20 nm) in managing the dental pain during tooth
separation.
A total of 40 patients including ten males and 30 females
between 20 to 30 years who met the inclusion criteria were introduced with four
sets of visual analog scales (VAS) after the insertion of the separating
elastics to measure pain instantly, at 48 h, 72 h, and seven days. Patients
were categorised into control and experimental groups. The experimental group
went through 180 mW, 22 s, 4 J, 8 J/cm2, 0.36 W/cm2, spot of 0.5 cm2, spot
diameter 0.8 cm LED phototherapy at the
corresponding times to which VAS performed. Both groups exhibited an elevation
in pain 48 h after the elastic tooth separator insertion, a reduction in pain
72 h after its establishment and after 7 h attained the lowest level of pain.
The experimental group always presented a statistically significant lower level
of pain (p < 0.05), excluding the time of installation (T1) when compared to
the control group.
The outcomes reflected a significant role of LED
phototherapy in reducing pain associated with orthodontic procedures.
