Objective: This case report proposes a treatment for dentin hypersensitivity (DH) using photobiomodulation (PBT) with low power diode laser. Methods and Results: Male patient, 28 years old, reporting “dental sensitivity,” diagnosed by anamnesis and intraoral examination, with non-carious cervical lesions (NCCL) and DH on teeth 15 to 25, with different pain intensities, measured with visual analogue scale (VAS). For DH treatment, a PBT was proposed, with 808nm, 100mW, 20s and 2J of energy, applied during 3 sessions, with one-week interval and reevaluation after 30 days. After the first session, the patient reported improvement of sensitivity in all teeth, except for 15, that remained sensitive even during the reevaluation. Conclusion: PBT was effective in DH treatment, with desensitization being observed for 30 days in 90% of treated teeth.

ABSTRACT Objective The evaluation of selective activation of C-fibers to record evoked potentials using the association of low-power diode laser (810 nm), tiny-area stimulation and skin-blackening. Method Laser-evoked potentials (LEPs) were obtained from 20 healthy young subjects. An aluminum plate with one thin hole was attached to the laser probe to provide tiny-area stimulation of the hand dorsum and the stimulated area was covered with black ink. Results The mean intensity used for eliciting the ultra-late laser-evoked potential (ULEP) was 70 ± 32 mW. All subjects showed a clear biphasic potential that comprised a negative peak (806 ± 61 ms) and a positive deflection (1033 ± 60 ms), corresponding to the ULEP related to C-fiber activation. Conclusion C-fiber-evoked responses can be obtained using a very low-power diode laser when stimulation is applied to tiny areas of darkened skin. This strategy offers a non-invasive and easy methodology that minimizes damage to the tissue.

Abstract A vertical cavity laser hygrometer has been developed for balloon-borne measurements. This hygrometer meets many of the specifications that are required for common weather balloon instrumentation, including weight, size, time response, and sensitivity. In addition, the system cost has been dramatically lowered relative to prior diode laser instruments. Sensitivity of 2 and 0.9 μbar at low- and high-altitude conditions, respectively, has been obtained in a 1-s measurement period, with the strong possibility of improved performance in the near future. The engineering advances that are demonstrated by this system make balloon-borne diode laser hygrometry a practical technique for more frequent use.
