Quantitative Assessment of the Efficacy of Two Irrigation Activation Systems
Bu çalışma, kök kanal tedavisinde kullanılan iki farklı irrigasyon (kanal yıkama) aktivasyon sisteminin (XP-endo Finisher ve EndoActivator) etkililiğini karşılaştırmıştır. Çalışmaya, daha önce kök kanal tedavisi görmüş ancak kök ucunda kronik iltihabi lezyon (chronic apical periodontitis) bulunan ve yeniden tedavi gereken dişler dahil edilmiştir. Faz uygulanmayan bir çalışma olup tamamlanmıştır.

Inclusion Criteria: * root canal-treated teeth exhibiting clinical and radiographic evidence of chronic apical periodontitis lesions. * Teeth with post-treatment apical periodontitis had endodontic therapy completed more than 2 years earlier and required retreatment. * Radiographically, the diameter of the periapical radiolucency ranged from 2 to 7 mm. * Termini of the root canal fillings ranged from 0-4 mm short of the radiographic apex, with no overfilling. * The teeth had intact coronal restorations, with no obvious exposure of the root-filling material to the oral cavity. * Selected teeth had enough crown structure for adequate isolation with a rubber dam and showed an absence of periodontal pockets or attachment level deeper than 4 mm. Exclusion Criteria: * teeth from patients who had received antibiotics within the previous 3 months or who had any general disease, teeth that could not be properly isolated with rubber dam, teeth with absence of coronary sealing, teeth with periodontal pocket depth \>4 mm; and teeth with crown/root fracture. Only one tooth was included from each patient.
