Conclusion the MTA products were effective for the root canal obturation and appeared to contribute to the significant reduction or complete regression of periapical lesions in teeth treated. A statistically significant decrease in the sizes of periapical lesions was consistently observed at follow-up periods (p 0.05). Results the positive clinical outcome was recorded in 24 (88.9%) cases, while radiographic success was present in 26 (96.3%) cases.

Control follow-ups were done three, six, 12, and 24 months following the completion of treatment. Definitive obturation was performed with ProRoot MTA (Dentsply Tulsa Dental Specialties, Tulsa, OK, USA) or MTA+ Cerkamed (Cerkamed, Stalowa Wola, Poland).

Methods Twenty-seven traumatized single-rooted permanent teeth diagnosed with necrotic pulps and chronic periapical lesions were treated with non-surgical procedure using a tri-antibiotic paste and calcium hydroxide as intra-canal medication. Adobe Photoshop CS (San Jose, CA, USA) image-analysis software was used for healing assessment. Introduction/Objective the purpose of this study was to assess effectiveness of endodontic root canal procedures in traumatized permanent teeth with necrotic pulps and chronic periapical lesions after definitive obturation with mineral trioxide aggregate (MTA) products. Prikazana metodologija može biti predložena za svakodnevnu kliničku praksu. Zaključak MTA proizvodi su efikasni u opturaciji korenskih kanala i čini se da doprinose značajnom smanjenju ili potpunoj regresiji periapikalnih lezija u tretiranim zubima. Statistički značajno smanjenje veličine periapikalnih lezija primećeno je u svim periodima (p 0,05). Rezultati Pozitivan klinički ishod zabeležen je u 24 (88,9%) slučaja, dok je radiografski uspeh bio prisutan u 26 (96,3%) slučaja. Kontrolni pregledi obavljeni su tri, šest, 12 i 24 meseca posle završetka lečenja. Definitivna opturacija izvedena je pomoću ProRoot MTA ili MTA+ Cerkamed. Metode Dvadeset i sedam traumatizovanih jednokorenih stalnih zuba sa nekrotičnom pulpom i hroničnim periapikalnim lezijama tretirani su nehirurškim procedurama pomoću triantibiotske paste i kalcijum-hidroksida kao intrakanalnog medikamenta. Softver za analizu slike Adobe Photoshop CS korišćen je za procenu regeneracije. Uvod/Cilj Svrha ove studije bila je procena efikasnosti endodontskog tretmana traumatizovanih stalnih zuba sa nekrotičnom pulpom i hroničnim periapikalnim lezijama posle definitivne opturacije mineralnim trioksidnim agregatom (MTA).
