Abstract

Svrha je ovog diplomskog rada navesti uzroke obojenja zubi te prikazati sredstva i tehnike za
izbjeljivanje avitalnih zubi. Izbjeljivanje zubi je postupak kojim se posvjetljuje prirodna boja zubi
ili se uklanjaju stečene diskoloracije na zubima. Uzroci obojenja zubi mogu biti ekstrinzični
(vanjski), intrinzični (unutarnji) i kombinirani. Ekstrinzična, odnosno vanjska obojenja nastaju
prilikom konzumacije obojene hrane i pića te starenjem. Većina diskoloracija koje su uzrokovane
vanjskim obojenjima uspješno se uklanjaju profesionalnim čišćenjem zubi, korištenjem pasti za
izbjeljivanje ili vanjskim izbjeljivanjem zubi. Intrinzična, odnosno unutarnja obojenja možemo
podijeliti na lokalna i sistemska. To su diskoloracije koje mogu nastati tijekom odontogeneze ili
nakon erupcije zuba. Glavni uzroci lokalne intrinzične diskoloracije su endodontski materijali u
pulpnoj komorici, nekrotični nusprodukti i neodgovarajuće ispiranje korijenskog kanala nakon
ekstirpacije pulpe. Sistemski uzroci intrinzičnog obojenja nastaju pod utjecajem okolišnih faktora
za vrijeme ili nakon razvoja zuba ili kao rezultat genetskih čimbenika. Intrinzične se diskoloracije
uklanjaju unutarnjim, odnosno avitalnim izbjeljivanjem zubi. Unutarnje izbjeljivanje zubi
minimalno je invazivna, konzervativna, relativno jednostavna i učinkovita metoda za izbjeljivanje
endodontski liječenih zubi. Postoji nekoliko tehnika unutarnjeg izbjeljivanja, a najčešće se
upotrebljava walking bleach tehnika. Ostale tehnike uključuju termokatalitičku tehniku i tehniku
unutarnjeg/vanjskog izbjeljivanja. Prije obavljanja zahvata potrebno je uzeti sve anamnestičke
podatke te obaviti temeljiti klinički pregled s obzirom na to da su preduvjeti zdrava parodontna
tkiva i pravilno zabrtvljen i s podlogom zaštićen korijenski kanal kako bi se spriječile posljedične
komplikacije ako sredstvo za izbjeljivanje dođe u kontakt s parodontnim ili periapikalnim tkivom.

Abstract (english)

The aim of this graduation thesis is to describe causes of tooth discoloration and show products
and techniques for non-vital teeth whitening. Teeth whitening is a process in which a natural tooth
color is whitened or existing teeth discoloration removed. Causes of tooth discoloration can be
extrinsic (external), intrinsic (internal) or combined. Extrinsic or external discoloration is caused
by consumption of colored foods and drinks as well as aging. Majority of discolorations caused
by external colorations can be successfully removed by professional teeth cleaning, by using
whitening toothpastes or by external teeth whitening. Intrinsic or internal discolorations can be
divided into local and systemic. These are discolorations that can occur during odontogenesis or
after tooth eruption. The major causes of local intrinsic discoloration are endodontic materials in
pulp chamber, necrotic byproducts and inadequate root canal irrigation after pulp extirpation.
Systemic causes of intrinsic discolorations occur under the influence of environmental factors
during or after tooth development or as a result of genetic factor. Intrinsic discolorations are
removed by internal or non-vital tooth whitening. Internal tooth whitening is minimally invasive,
conservative, relatively easy and effective method of whitening endodontically treated teeth. There
are a few techniques of internal whitening and “the walking bleach” technique is the one most
often used. Other techniques include thermocatalytic technique and internal/external whitening.
Before tooth whitening, it is necessary to collect anamnestic data and perform thorough clinical
examination because healthy periodontal tissues and properly sealed root canal are prerequisitesfor
prevention of potential complications if whitening agent comes in contact with periodontal or
periapical tissues.
