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
/ studio
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 […]
Use of Long Pulse Nd:YAG 1064nm Laser for Treatment of Rosacea Telangiectatica
/ studio
A clinical study was performed in which 23 female patients were treated with long pulse Nd:YAG laser light (DualisSP, Fotona, Slovenia) for rosacea teleangiectatica. Patients were treated in one, two or three sessions, depending on facial telangiectasia clearance success. The time interval between sessions was 6 weeks. Treatment parameters were set according to the treated […]
Clinical Results in Thermolytic and Sub-Thermolytic Q-Switched Nd:YAG Skin Rejuvenation
/ studio
Thermolytic and sub-thermolytic Q-Switched Nd:YAG treatment are able to rejuvenate the skin safely and effectively. It is more and more common for practioners (especially in Asia) to use Q-Switched Nd:YAG laser on indications other than pigmented lesions and tattoos, which are the application areas in which Nd:YAG has traditionally been used. Recent clinical results in […]
Low level Laser in Dentistry
/ studio
A wide range of different lasers are used in modern dentistry. The Erbium:YAG laser has a potential of replacing the drill in selected situation; the carbon dioxide laser is a valuable tool in oral surgery; the Argon laser is used in minor surgery and composite curing; the Nd:YAG is used in pocket debridment, tissue retraction […]
A Magic Wand for the Community Dental Office? Observations from the British Columbia Oral Cancer Prevention Program
/ studio
Oral cancer is a deadly disease. It is often diagnosed late with considerable spread, resulting in a high mortality rate and treatment-associated morbidity. New devices entering the market have stimulated a renewed interest in oral cancer screening among dental professionals. The British Columbia Oral Cancer Prevention Program (BC OCPP) is actively involved in research related […]
Evidence-Based Decision-Making: Should the General Dentist Adopt the Use of the VELscope for Routine Screening for Oral Cancer?
/ studio
The VELscope (Visually Enhanced Lesion Scope) is currently being marketed to general dentists. Advertisements claim that this handheld device visually enhances a clinician’s ability to detect oral cancer. The technology is based on the premise that normal cells will glow when exposed to fluorescent light, whereas abnormal cells (not necessarily only cancer or precancerous cells) […]
Früherkennung von Mundhöhlenkrebs mittels Gewebefluoreszenz
/ studio
Plattenepithelkarzinome der Mundhöhle entstehen zum Teil aus Vorstufen, die klinisch als Erythro- oder Leukoplakie imponieren. In Deutschland erkranken nach Daten des Robert Koch-Institutes jährlich rund 7 700 Männer und 2 300 Frauen. Dies entspricht einem Anteil von knapp fünf Prozent an allen bösartigen Neubildungen bei Männern, beziehungsweise einem Prozent bei Frauen. Zur Diagnostik wird neben […]
Tracing the “At-Risk” Oral Mucosa Field with Autofluorescence
/ studio
A new paradigm in the way we envision tissue change during carcinogenesis has evolved in recent years. From a clinical standpoint, this paradigm has altered how we view “at-risk” tissue. Rather than focusing on clinical lesions, we often discuss “field” changes involving the expansion of genetically and epigenetically altered cells within a tissue, and not […]
