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 […]
A Novel Quantum Square Pulse (QSP) Mode Erbium Dental Laser
Recently, a novel quantum square pulse (QSP) modality has been added to the range of treatment parameters of variable square pulse (VSP) Er:YAG dental lasers. In this paper, physical mechanisms enabling the QSP technology are reported. One of the major advantages of the QSP mode is that it significantly reduces undesirable effects of laser beam […]
L’utilizzo del laser nelle varie branche odontoiatriche. Valutazioni tecniche e cliniche
La radiazione Laser: dalla fisica alle applicazioni cliniche Tra i vari incipit di una introduzione all’argomento il più comune fa riferimento all’acronimo laser, ossia “light amplification by stimulated emission of radiation” (amplificazione della luce attraverso l’emissione stimolata di radiazione). E’ decisamente una estrema ma efficace sintesi di un percorso storico scientifico e tecnologico che ha […]
Dental Laser Drilling: State of the Art with the Latest Generation of variable Square Pulse Erbium Dental laser Systems
The most recent technological breakthroughts incorporated in the latest generation of Variable Square Pulse (VSP) Er:YAGdental lasers involve two additional features: SSP (Super Short Pulse) mode for extremely fine and minimal invasive laser ablation; and MAX mode for maximum optical drilling speeds. The objective of this study was to make a comparision between the two […]
Laser Profilometry for the Characterization of Craters Produced in Hard Dental Tissues by Er:YAG and Er,Cr:YSGG Lasers
A new, highly accurate and repeatable methodology based on the principle of optical triangulation to measure ablation rates in hard dental tissues is introduced. Using this methodology, a comparison is made between the two leading laser wavelengths for hard tissue procedures in dentistry, Er:YAG (Fidelis Plus III, Fotona) and Er,Cr:YSGG (Waterlase MD, Biolase). In-vitro measurements […]
Dental laser drilling: Achieving optimum ablation with the latest generation Fidelis laser systems
This paper provides an overview of the scientific principles of hard dental tissue laser procedures and discusses the influence of laser wavelength, pulse duration and pulse energy. Erbium lasers have been found to be a safe and efficient technological solution for the manipulation of hard dental tissues. The ability to precisely control laser pulse duration […]
Lasers in Endodontics
This paper describes and discusses the use of the Nd:YAG and diode lasers in endodontics. Clinical studies clearly show advantages of laser treatments over currently-used conventional methods and techniques. The most important advantages are improved disinfection efficacy, more effective root canal cleaning, reduction of permeability, reduction of micro-leakage, and elimination of the need to use […]
State of the Art in Lasers for Dentistry
Lasers have been used in dentistry since 1964. The idea was to be able to treat both soft tissues and hard tissues, including bone, without direct contact, vibrations and pain. Since the early 90’s lasers have been applied in a wide variety of dental application areas. In this paper Prof. dr. Norbert Gutknecht, President of […]
