Abstract

Suvremeni postupci izbjeljivanja zubi uključuju preparate na bazi vodikovog peroksida u manjim ili većim koncentracijama ovisno o tome provodi li se izbjeljivanje kod kuće ili u ordinaciji pod kontrolom stomatologa. Preparati za izbjeljivanje najčešće dolaze u obliku gela, a mogu biti rabljeni u prisutnosti ili bez prisutnosti izvora svjetlosti. Svjetlost pri tom ima ulogu aktivatora odnosno katalizatora koji povećava apsorpciju gela i ubrzava kemijski proces oksidacije. Drugim riječima, svjetlost ubrzava i poboljšava djelovanje gela, a time i cjelokupni postupak izbjeljivanja zubi. Izvori svjetlosti mogu se temeljiti na halogenoj, LED/diodnoj i laserskoj tehnologiji. Tržište danas nudi sve veći broj profesionalnih sustava za izbjeljivanje. Neki od poznatih brendova koji koriste aktivacijski izvor svjetlosti su: ZOOM! izvor svjetlosti (metal halid svjetlost), Beyond (halogeno svjetlo), LumaCool (halogeno svjetlo), BriteSmile (gas plasma/LED), LaserSmile - biolaser, Sapphire - plasma arc svjetlost. Premda se kod svih svjetlosnih izvora oslobaña odreñena količina toplinske energije koja može imati štetan termalni učinak na vitalitet zuba; uzrokovati pojavu preosjetljivosti i termalne boli, suvremene tehnologije ugradnje filtera za infracrvenu i ultraljubičastu svjetlost smanjile su termalni učinak na minimum ili ga u nekim sustavima u potpunosti uklonile. S druge strane toplinski učinak na pulpu može se smanjiti kraćim vremenom izloženosti zuba svjetlosnom izvoru, debljim slojem sredstva za izbjeljivanje koji se nanosi na zub, te uporabom sredstva za izbjeljivanje koje jače apsorbira svjetlost zbog čega će se smanjiti prijenos svjetlosne odnosno toplinske energije kroz zub.

Abstract (english)

Current methods of teeth whitening treatments include products based on hydrogen peroxide in concentrations greater or lesser depending on how teeth whitening is carried out; at home or in office under the control of the dentist. Preparations for
bleaching usually come in the form of gels, and can be used in the presence or without light sources. The light functions as a catalyst or activator, which increases the absorption of the gel and speeds up the chemical process of oxidation, ie. light accelerates and improves the function of gel, and thus the whole teeth whitening treatments. Light sources can be based on halogen, LED/diode and laser technology. The market today offers a growing number of professional whitening systems. Some of the brands that use the activation light source are: ZOOM! light source (metal halide light), Beyond (halogen light), LumaCool (halogen light), BriteSmile (gas plasma / LED), LaserSmile - A Biolase laser, Sapphire - plasma arc light. Although in all light sources a certain amount of heat is released that can have a detrimental thermal effects on the vitality of the teeth, causing the occurrence of hypersensitivity and thermal pain, the modern technology installed filters for infrared and ultraviolet light to reduce the thermal effect to the minimum or in some systems eliminates it. On the other hand, thermal effects on the pulp of teeth can be lessened by reducing the exposure to dental light source, increasing the thickness of the
