Abstract

Endodontsko liječenje zubi je terapijski postupak čija provedba podrazumijeva uklanjanje upalno promijenjene pulpe, smanjenje broja mikroorganizama u endodontskom prostoru, adekvatno trodimenzionalno punjenje korijenskih kanala te pravovremenu postendodontsku opskrbu. Mehaničko oblikovanje i čišćenje korijenskih kanala provodi se ručnim i strojnim instrumentima. Strojne tehnike instrumentacije inovativni su pristup u provedbi endodontske terapije zuba. Strojne endodontske sustave dijelimo na: rotacijske, recipročne, adaptivne i vibracijske. Rotacijski sustavi koriste pokret stalne rotacije uz manje brzine, reciprocitetni sustavi izmjenjuju pokret instrumenta u smjeru suprotnom od smjera kazaljke na satu, adaptivni sustavi prilagođavaju smjer kretnje instrumenta u korijenskom kanalu, a vibracijski sustavi koriste pokrete unutra-van. Rotacijski sustavi F360 i F6 SkyTaper upotrebom superelastične NiTi legure i novog dizajna instrumenta koji u poprečnom presjeku imaju oblik dvostrukog slova S, pokazali su visoku učinkovitost u uklanjanju zaostatnog sloja, fleksibilnost, veću otpornost na ciklički zamor i lom te dobru prilagodbu različitim anatomijama korijenskih kanala. Primjenom strojne instrumentacije tijekom čišćenja i širenja korijenskih kanala skraćuje se vrijeme potrebno za provedbu endodontske terapije, smanjuje se učestalost transportacije te povećava efektivnost terapije. Inovativnim tehnikama i materijalima, dijagnostičko-terapijski postupci u endodontskoj terapiji ostvaruju napredak i sugeriraju njihovu svakodnevnu kliničku primjenu.

Abstract (english)

Endodontic dental treatment is a therapeutic procedure the implementation of which involves the removal of inflammatory pulp, reduction of the number of microorganisms in the endodontic space, adequate three-dimensional filling of the root canals and timely postendodontic supply. Mechanical shaping and the cleaning of root canals is performed using hand and machine tools. Machine instrumentation techniques are an innovative approach in the implementation of endodontic tooth therapy. Machine endodontic systems are divided into: rotary, reciprocal, adaptive and vibrational. Rotary systems use constant rotation at lower speeds, reciprocal systems rotate the instrument counter-clockwise, adaptive systems adjust the direction of the movement of the instrument in the root canal and vibration systems use inward-outward movements. The F360 and F6 SkyTaper rotary systems, using a superelastic NiTi alloy and a new S-shaped cross-sectional instrument design, have shown high efficiency in residual backbone removal, flexibility, greater resistance to cyclic fatigue and fracture and good adaptation to different root canal anatomies. The use of machine instrumentation during root canal cleansing and expansion shortens the time required to perform endodontic therapy, reduces the frequency of transport and increases the effectiveness of therapy. With innovative techniques and materials, diagnostic and therapeutic procedures in endodontic therapy make progress and suggest their daily clinical application.
