Photo-thermal ablative and non-ablative fractional resurfacing and remodeling have become extremely popular due to the lower rate of complications and side effects compared to conventional full-face procedures. Clinical results are nevertheless quite different and have prompted researchers to find new strategies to improve treatment outcomes. Sequential laser layering techniques have been successfully used in PWS […]
Narrow band (light) imaging of oral mucosa in routine dental patients.
/ studio
The purpose of this investigation was to determine the value of adding narrow band (light) imaging (NBI) to the standard oral soft tissue examination process used to detect mucosal change. A total of 620 dental patients who came to the clinic for regular dental evaluation or for treatment of acute dental problems were given a […]
Beyond Customary Paradigm: FRAC3® Nd:YAG Laser Hair Removal
/ studio
VSP (Variable Square Pulse) Nd:YAG laser devices hold the most prominent position among all available laser sources for hair removal. This is due to the long wavelength (1064 nm) which Nd:YAG devices produce. Light with a wavelength of 1064 nm lies in a biological absorption region that allows light to penetrate deep into the skin, […]
Treating Melasma with Sub-Thermolytic Q-Switched Nd:YAG
/ studio
The successful treatment of melasma by sub-thermolytic Q-Switched Nd:YAG laser therapy has been demonstrated by several investigators. The minimization of side-effects and reoccurence in high phototype patients is a major topic of current research. The approaches taken and the results obtained are reviewed in this paper. articolo completo Autore Tomaz Bevec
Teoria del laser
/ studio
Il Laser è un dispositivo le cui applicazioni si stanno diffondendo in un ampio ventaglio di settori. Laser è l’acronimo di Light Amplification by Stimulated Emission of Radiation, cioè amplificazione di luce mediante emissione stimolata di radiazione. Il primo amplificatore di radiazione elettromagnetica fu realizzato con ammoniaca nella zona delle microonde, e venne chiamato Maser, […]
From laser cooling to Bose-Einstein condensation
/ studio
Importance of the quantum statistics (BE orFD) Bose-Einstein condensation, coherence, Fermi sea, superfluidity, quantum phase transitions… Links with condensed matter physics A wide range of applications: High precision spectroscopy (Doppler-free lines) Quantum information and quantum computation Metrology (fountains, optical clocks…) New insights in condensed matter physics: Bloch oscillations, superfluid-insulator transitions, Cooper pairing, search for Anderson […]
Lasers in Implantology
/ studio
Implants are one of the most widely accepted and innovative applications in dentistry. The possibilities to save healthy tooth structure without grinding the teeth for prosthetic bridge treatments, or to give back the ability to chew to a patient who has missing or even no teeth is almost miraculous. Implant restorations have played significant roles […]
Comparison of Heat Deposition of Er:YAG and Er,Cr:YSGG Lasers in Hard Dental Tissues
/ studio
This paper describes a comparative study of residual heat deposition of Er:YAG and Er,Cr:YSGG lasers during ablation of hard dental tissues. Residual heat deposition was obtained from measured irradiated hard tissue temperature decay characteristics immediately following Erbium laser pulses. The measured residual heat was larger in enamel than in dentine for both Er:YAG and Er,Cr:YSGG […]
A Novel Er:YAG Laser-Assisted Tooth Whitening Method
/ studio
In this paper we describe a novel, erbium laser-assisted whitening method, TouchWhiteTM, which pertains to chemical strategies for removing tooth stains by means of laser-activated aqueous gels or pastes. The TouchWhiteTM method makes use of the fact that the Er:YAG laser wavelength has a water absorption peak in the vicinity of 3 μm. Since water […]
