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?
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
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
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 […]
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 […]
Theory of laser
The name LASER is an acronym for Light Amplification by the Stimulated Emission of Radiation. Light is really an electromagnetic wave. Each wave has brightness and color, and vibrates at a certain angle, so-called polarization. This is also true for laser light but it is more parallel than any other light source. Every part of […]
10/02 – Parodontosi
La parodontosi, o piorrea, è un processo infettivo causato da batteri. Questo processo infettivo è caratterizzato in una prima fase da gengivite (infiammazione delle gengive) con presenza di edema (gonfiore), rossore e sanguinamento delle gengive, accumulo di placca batterica e tartaro. Nella seconda fase l’azione dei batteri determina riassobimento osseo e la formazione di una […]
Scanner Optimized Efficacy (SOE) Hair Removal with the VSP Nd:YAG Lasers
In laser hair removal, it is preferred for many clinical and technical reasons to use small to medium size laser spotsizes. However, manually aiming a small laser beam hundreds of times to cover a larger skin area can lead to uneven coverage and can result in missed areas and excess heating due to pulse stacking. […]
FRAC3: Three Dimensional Non-Ablative Fraction Laser Skin Rejuvenation
A novel self-indiced non-ablative three-dimensional fractional FRAC3 method for skun rejuvenation is described. The method utilizes short pulse duration/high peak power density of Nd:YAG Accelera mode laser pulses. The Accelera pulses produce a three-dimensional fractional pattern in the epidermis and dermis, with demage islands located predominatly at the sites of skin imperfections. Thermal measurements in-vivo […]
Sensitivity of direct tissue fluorescence visualization in screening for oral premalignant lesions in general practice
Various specialty clinics and research centers have conducted studies of direct tissue fluorescence visualization as a screening technique for oral premalignant lesions and early oral squamous cell carcinoma (OSCC). The effectiveness of the VELscope in a private practice setting is unknown. This pilot study is the first report to assess the VELscope system as a […]
