Carlos Menezes Aguiar Rua Aristides Muniz, 70/501 Boa Viagem Recife PE 51020-150 Brazil telefon: 55 81 3467 6821 [email protected] Sažetak Svrha istraživanja: Željela se procijeniti učinkovitost sustava ProTaper Universal RetreatmentTM i ručnih instrumenata kod endodontske revizije korištenjem dvaju otapala gutaperki – Orange Oila i Eucalypthola. Materijali i metode: Odabrano je 40 meziobukalnih korijena. Podijeljeni su u četiri skupine po 10 uzoraka: I. skupina – punjenje je uklonjeno sustavom ProTaper Universal RetreatmentTM i otapalom Orange Oilom; II. skupina – korijeni su očišćeni sustavom ProTaper Universal RetreatmentTM i otapalom Eukaliptolom; III. skupina – uporabljene su pilice Hedström i K-proširivači te otapalo Orange Oil; IV. skupna – punjenje je uklonjeno pilicama Hedström i K-proširivačima te otapalom Eukaliptolom. Uzorke su pregledala tri endodonta ne bi li pronašli ostatke materijala za punjenje. Statistička analiza obavljena je testovima Fisher Exact, Hi-kvadrat i Mann-Whitney. Postavljena granica značajnosti bila je 0,05. Rezultati: I. skupina – uklonjeno je 73,3 posto materijala iz koronarne trećine, 46,7 posto iz srednje i 23, 3 posto iz apikalne; II. skupina – uklonjeno je 83,3 posto materijala iz koronarne trećine, 43 posto iz srednje i 40 posto iz apikalne; III. skupina – uklonjeno je 90 posto materijala iz koronarne trećine, 80 posto iz srednje i 70 posto iz apikalne; IV. skupina – uklonjeno je 100 posto materijala iz koronarne trećine, 80 posto iz srednje i 63,3 posto iz apikalne. Zaključak: K-proširivačima i pilicama Hedström postignuti su bolji rezultati negoli sustavom ProTaper Universal RetreatmentTM u uklanjanju materijala za punjenje, bez obzira na to koje se otapalo upotrijebilo.

Comparison of debris extruded apically and working time used by ProTaper Universal rotary and ProTaper retreatment system during gutta-percha removal
OBJECTIVE The aim of this study was to evaluate the in vitro action of ProTaper retreatment files and ProTaper Universal in the retreatment of mandibular premolars. MATERIAL AND METHODS The amount of debris extruded apically was measured and the time to reach the working length and to complete the removal of gutta-percha was observed. Thirty teeth had their canals prepared using ProTaper Univ...

AIM To test the efficacy of a two-stage retreatment method in which the Self-Adjusting File (SAF) is used to remove root canal filling residue left in the canal after using ProTaper Universal retreatment files. METHOD One of the curved mesial canals of 25 extracted mandibular molars was instrumented up to ProTaper F2, followed by NiTi K-files up to size 45 and filled. Radiographs of these can...
متن کاملComparison of WaveOne and ProTaper Universal Preparation Systems in the Amount of Smear Layer/Debris Production: an in-vitro SEM Study
Background and Aim: Debris and the smear layer that remain after root canal preparations may result in failure of root canal therapies. The aim of this study was to compare the smear layer formation and the amount of residual debris following the use of WaveOne and ProTaper rotary files in mesiobuccal root canals of upper first molars by scanning electron microscopy (SEM). Materials and Method...
متن کاملEfficacy of 2 reciprocating systems compared with a rotary retreatment system for gutta-percha removal.
INTRODUCTION The maximum removal of root canal filling material is essential for successful endodontic retreatment. The purpose of this study was to assess the efficacy of 2 reciprocating systems (Reciproc [VDW, Munich, Germany] and WaveOne [Dentsply Maillefer, Ballaigues, Switzerland]) compared with a nickel-titanium (NiTi) rotary system (ProTaper Universal Retreatment [Dentsply Maillefer]) in...
