808-nm laser therapy with a flat-top handpiece photobiomodulates mitochondria activities of Paramecium primaurelia (Protozoa)Lasers in Medical Science - Tập 31 - Trang 741-747 - 2016

Photobiomodulation is proposed as a non-linear process, and only low-level laser therapy (LLLT) is assumed to stimulate exposed cells, whereas high powered laser and fluences can cause negative effects, exhausting the cell’s energy reserve as a consequence of excessive photon-based stimulation. In our work, we investigated and compared the effects of 808-nm diode laser (CW) with a new flat-top han...... hiện toàn bộ
Comparison of visual outcomes between 120-µm and 140-µm cap thicknesses 12 months after small incision lenticule extractionLasers in Medical Science - Tập 37 Số 6 - Trang 2667-2673 - 2022
Gülmez, Mehmet, Ural Fatihoğlu, Özlem, Tekçe, Abdülhakim
To compare visual and refractive outcomes as well as changes in high-order aberrations in patients with 120- versus 140-µm cap thicknesses 12 months after small incision lenticule extraction. Ninety-four patients were randomized to receive small incision lenticule extraction with either a 120-µm cap thickness (n = 47) or a 140-µm cap thickness (n = 47) to treat myopia or myopic astigmatism, i...... hiện toàn bộ
New evidence from hyperspectral imaging analysis on the effect of photobiomodulation therapy on normal skin oxygenationLasers in Medical Science - Tập 37 - Trang 1539-1547 - 2021

The aim of this study was to assess the changes induced by photobiomodulation therapy in oxygenation of normal skin and underlying tissue using hyperspectral imaging combined with a chemometric regression approach. Eleven healthy adult volunteers were enrolled in this study. The dorsal side of the left hand of each subject was exposed to photobiomodulation therapy, while the correspondent side of ...... hiện toàn bộ
Mast cell concentration in the wound healing process of incisions made by different instrumentsLasers in Medical Science - Tập 24 - Trang 585-590 - 2008

The aim of this study was to compare the concentration of mast cells (MCs) in the healing process of incisions. Thirty rats were submitted to six linear incisions each, performed in the dorsal skin by carbon dioxide (CO2) and diode lasers, electrocautery and conventional scalpel. The animals were euthanized at intervals of 0 h, 24 h, 48 h, 72 h, 7 days and 14 days after the incisions had been made...... hiện toàn bộ
Dispersion of near-infrared laser energy through radicular dentine when using plain or conical tipsLasers in Medical Science - Tập 33 - Trang 251-255 - 2017
Christine Yi Jia Teo, Roy George, Laurence J. Walsh
The aim of this study was to investigate the influence of tip design on patterns of laser energy dispersion through the dentine of tooth roots when using near-infrared diode lasers. Diode laser emissions of 810 or 940 nm were used in combination with optical fiber tips with either conventional plain ends or conical ends, to irradiate tooth roots of oval or round cross-sectional shapes. The lasers ...... hiện toàn bộ
