Abstract

Endodontski prostor čini središnji dio zuba, a sastoji se od pulpne komore i jednog ili više korijenskih kanala. Morfologija korijenskih kanala često je iznimno složena i kao takva predstavlja veliki izazov u endodontskom liječenju. Vertucci je opisao osam tipova mogućih morfoloških varijacija korijenskih kanala koji daju osnovne informacije o njihovom broju te mogućem spajanju ili račvanju na svom putu od dna pulpne komore do vrha korijena. Ipak, suvremenim tehnikama istraživanja morfologije kanalnog sustava utvđeno je da je njegova konfiguracija puno kompleksnija. Preduvjet je svakog endodontskog liječenja temeljito poznavanje unutarnje anatomije pojedinog zuba, a u to spadaju položaj pulpne komore, broj i položaj korijenskih kanala, oblik njihovog poprečnog presjeka i smjer, ali i moguće varijacije koje se u pojedinom zubu mogu naći. Nepronalaženje prisutnog kanala često je uzrok lošeg ishoda terapije. Neprepoznavanje zahtjevne anatomije može biti uzrok brojnim proceduralnim greškama za vrijeme endodontskih postupaka. Uspjeh endodontskog liječenja ovisi o učinkovitoj kemomehaničkoj obradi i oblikovanju kanala, kao i o potpunom trodimenzionalnom punjenju kojim se taj prostor brtvi. Tim se postupcima eliminiraju mikroorganizmi kao glavni uzročnici bolesti pulpe i periapeksa i sprječava se reinfekcija kanala. Mikroorganizmi, osim glavnog korijenskog kanala, nastanjuju i teže dostupna područja kao što su istmusi, ramifikacije, dentinski tubulusi i recesusi, što značajno otežava učinkovitu obradu kanala. Pridržavanjem učinkovitih protokola za čišćenje tih područja, broj mikroorganizama se smanjuje ispod kritične razine, a adekvatnim punjenjem do apikalnog stopa i dobrim koronarnim brtvljenjem sprječava se dotok hranjivih tvari i njihovo posljedično preživljenje i umnažanje.

Abstract (english)

The endodontic space forms the central part of the tooth and consists of a pulp chamber and one or more root canals. Root canal morphology is often extremely complicated and such as presents a major challenge in endodontic treatment. Vertucci described eight types of possible morphological variations of root canals that provide basic information about their number and possible merging or branching on their way from the bottom of the pulp chamber to the root apex. Nevertheless, according to recent researches of root canal system it has been established that its configration is much more complex. A prerequisite for any endodontic treatment is a thorough knowledge of the internal anatomy of each tooth, including the position of the pulp chamber, the number and the position of root canals, their cross-sectional shape and direction, but also possible variations that can be found in each tooth. Missed root canal is often the cause of a poor therapy outcome. Not recognizing a demanding anatomy can be the cause of many procedural errors during endodontic procedures. The success of endodontic treatment depends on efficient chemomechanical treatment and canal shaping, as well as on the complete three-dimensional filling by which this space is sealed. These procedures eliminate microorganisms as the main causes of pulp and periapical disease and prevent canal reinfection. Microorganisms inhabit not only the main root canal, but also hard-to-reach areas such as isthmuses, ramifications, dentinal tubules and recessions, which significantly complicates the efficient treatment of the canal. By adhering to effective protocols for cleaning these areas, the number of microorganisms is reduced below the critical level, whereas adequate filling to the apical stop and good coronary sealing prevents the influx of nutrients and their consequent survival and multiplication.
