An evaluation was made of the sterilizing effects of the Erbium:YAG laser at different power ratings upon dental structures in vitro. An in vitro study was made of 47 single-root teeth removed for periodontal reasons in the Oral and Maxillofacial Surgery Teaching Unit (Department of Medicine and Orofacial Surgery, Madrid Complutense University Dental School, Spain). […]
Clinical Uses of the Erbium Laser
Dentistry has a new weapon in the fight against tooth decay. This “light saber” of dentistry is the Erbium laser. The dental laser is the latest in modern innovations for the 21st Century. The Erbium lasers have proven safe and effective for the removal of tooth decay and cavity preparation in addition to many soft […]
A Novel Technique of Er:YAG Laser-Enhanced Early Implant Stability for Implant Dentistry: A Pilot Clinical Case Report
Over the years in implant dentistry, developments have been concentrated on implant design and surface treatment of titanium, and successful sseointegration is now considered as the minimum standard for all implants. To avoid bone necrosis, preparation of the osteotomy site is commonly achieved with a series of drills and copious water irrigation. Studies show that […]
Photodynamic Antimicrobial Chemotherapy in the General Dental Practice
Laser photonic energy can be absorbed by target tissue and molecular elements. In the surgical excision of tissue, such energy is rapidly converted into thermal energy that causes physical disruption and possible vaporization. Relative to each target tissue and corresponding incident laser wavelength exists a thermal threshold, below which the incident photonic energy values are […]
Fiber-tip drilling of hard dental tissues with Er:YAG laser
Specifics of fiber-tip ablation of hard dental tissues with mid infrared laser radiation are investigated in vitro. articolo completo Autori Boris Majaron Tatjana Prosen Dusan Sustercic Matjaz Lukac
Erbium lasers in dentistry
The first lasers were developed in 1964 and, almost immediately, the desire to use this new technology in medical applications began. The evolution and growth of the use of lasers in medicine during the last 2 decades occurred initially within the disciplines of ophthalmology, dermatology, and general surgery. The general acceptance today of the role […]
Il trattamento Laser In Medicina e Patologia Orale
I raggi laser, le più intense sorgenti luminose naturali o artificiali oggi conosciute, possono avere effetti estremamente potenti sui sistemi biologici. L’unicità del laser deriva da numerose e speciali proprietà quali l’alta intensità, la coerenza che permette di concentrarsi su un punto anche inferiore ad un micrometro, la collimazione, l’estrema mono-cromaticità e la possibilità di […]
Principi base del laser
I laser sono dispositivi che producono intensi fasci di luce che sono monocromatici, coerenti e altamente collimati. La lunghezza d’onda (colore) della luce laser è estremamente pura (monocromatica) rispetto ad altre fonti di luce, e tutti i fotoni (energia) che compongono il raggio laser hanno una relazione fissa di fase (coerenza) rispetto gli uni agli […]
Apparati laser in ambienti di lavoro: utilizzo in sicurezza
I LASER (Light Amplification by Stimulated Emission of Radiation) sono sorgenti di radiazione ottica con caratteristiche peculiari. A differenza delle normali sorgenti luminose, le emissioni laser sono di tipo monocromatico (una o pochissime lunghezze d’onda) e coerente (elevata collimazione del fascio radiante). Il laser ha ormai raggiunto un elevato grado di diversificazione tecnologica e numerosissime […]
Indications and limitations of Er:YAG laser applications in dentistry
Since the early 1960s, lasers have been used in medicine and dentistry. Research and studies have prepared the pathway for cavity preparation without pain and discomfort. Different wavelengths have been tested with variable results and several lasers have shown serious side-effects which could cause damage to dentin and enamel while insufficiently cutting dental hard tissues.
