Il Piercing, o body piercing, (dall’inglese to pierce, “perforare”) indica la pratica di forare alcune parti superficiali del corpo allo scopo di introdurre oggetti in metallo, spesso arricchiti con pietre preziose, osso, pietra o altro materiale, come abbellimento o pratica rituale. Il termine viene talvolta utilizzato anche per definire la pratica del play piercing o […]
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 […]
Metalli velenosi in bocca? NO GRAZIE! Molte persona hanno avuto ed hanno tuttora gravi problemi di salute a causa delle otturazioni dentali di amalgama (le così dette piombature d’argento). Anna Maria Pescatore
A considerable proportion of oral cancer and precancer is not clinically apparent and could contribute significantly to the late diagnosis and high mortality of oral cancer. A simple method to identify such occult change is needed. Patients in the Oral Dysplasia Clinics at British Columbiaare currently being examined with a simple hand-helddevice that permits the […]
Early identification of high-risk disease could greatly reduce both mortality and morbidity due to oral cancer. We describe a simple handheld device that facilitates the direct visualization of oral-cavity fluorescence for the detection of high-risk precancerous and early cancerous lesions. Blue excitation light 400 to 460 nm is employed to excite green-red fluorescence from fluorophores […]
Conventional visual examination and palpation remains the gold-standard for the identification of oral mucosal lesions. The purpose of this study was to investigate the adjunctive value of a chemiluminescent light source (ViziLite, Zila Pharmaceuticals, Phoenix, Arizona) and application of pharmaceutical grade toluidine blue (TBlue630, Zila Pharmaceuticals, Phoenix, Arizona) to further assess lesions identified during the […]
La fluorescenza è una proprietà tipica di alcune molecole, chiamate fluorofori, in grado di assorbire luce e riemetterla a una lunghezza d’onda maggiore. Nella pratica clinica, i fluorofori esogeni sono sostanze fluorescenti somministrate dall’esterno che si accumulano in specifici tessuti o si legano a specifici bersagli biologici, mentre i fluorofori endogeni sono sostanze fluorescenti normalmente […]
