Abstract

Endodontsko liječenje zuba je terapijski postupak obrade korijenskog kanala u cilju uklanjanja patološki promijenjenog tkiva i patogenih mikroorganizma. Kod neuspjeha endodontske terapije pristupa se kirurškom postupku uklanjanja vrška korijena zuba zajedno s patološki promijenjenim tkivom. Na korijenskom kanalu na mjestu resekcije izrađuje se retrogradni kavitet i ispunjava se s materijalom koji hermetički brtvi, u cilju sprječavanja prodora iritirajućih tvari iz korijenskog kanala u periapikalno područje.
Za retrogradno punjenje korijenskih kanala mogu se rabiti brojni materijali, u novije vrijeme prednost imaju bioaktivni materijali. Kvaliteta konačnog punjenja korijenskih kanala bit će uspješnija ukoliko odaberemo materijal s dobrim biološkim, kemijskim i mehaničkim svojstvima. U tu skupinu spadaju Mineral trioksid agregat, Biodentin i biokeramika.
Prednost bioaktivnih materijala je njihova biokompatibilnost, potiču reparaciju i regeneraciju parodontnih tkiva, ostvaruju kemijsku vezu sa dentinom, a nakon stvrdnjavanja lagano ekspandiraju čime osiguravaju dobro brtvljenje korijenskog kanala.

Abstract (english)

Endodontic treatment of a tooth is a therapeutic procedure of root canal management with the aim to remove pathologically altered tissue and pathogenic microorganisms. Surgical removal of a root apex and pathologically altered tissue around it is applied in case of endodontic therapy failure. After the resection, root-end cavity on the root canal is prepared and filled with a material that enables hermetic sealing, with the aim to prevent penetration of irritating substances from root canal into the periapical area.
Many materials may be used for retrograde root canal filling and in recent times, bioactive materials are preferred. Final root canal filling will be all the more successful if we choose a material with good biological, chemical and mechanical properties. Among the materials with such properties are the Mineral trioxide aggregate, Biodentine and bioceramics.
The main advantage of bioactive materials is their biocompatibility and the fact that they stimulate reparation and regeneration of periodontal tissues. In addition, they form chemical bonds with dentin and after hardening, they slightly expand, thus ensuring good sealing of the root canal.
