    CONSIDERATION OF THE THERAPEUTIC POTENTIAL OF IRRIGANTS IN ENDODONTIC THERAPY
    (Sciendo, 2018) Nogo-Zivanovic, Dajana; Bjelovic, Ljiljana; Ivanovic, Vladimir; Kanjevac, Tatjana; Tanaskovic, Irena
    Th e main objective of endodontic treatment is to remove vital and necrotic remnants of pulp tissue and microorganisms and their toxic products from the root canal. During chemo-mechanical endodontic preparation, a smear layer is formed on the wall of the canals. Due to an inability to remove all tissue remnants and the smear layer from the root canal by mechanical instrumentation, it is necessary to use irrigation to ensure suffi cient cleaning and disinfection of the largest part of the root canalicular system. The most commonly used irrigants are sodium hypochlorite (Na-OCl), ethylenediaminetetraacetic acid (EDTA), citric acid and chlorhexidine (CHX). Recently, the irrigants QMix and MTAD have been introduced to the market. Th ey are a mixture of diff erent components having antimicrobial, organolytic and mineralytic eff ects on canal detritus and the smear layer. Th is review article investigates irrigants in terms of the nature of their eff ect, their effi ciency, optimal concentration, and method of use, and the interactions between the irrigants most commonly used in endodontic therapy are discussed, with special emphasis on QMix and MTAD.

    Evaluation of permeability of root dentin after different irrigation protocols
    (Serbian Medical Association, 2018) Bjelović, Ljiljana; Krunić, Jelena; Stojanović, Nikola; Erić, Jelena; Kanjevac, Tatjana
    Introduction/Objective This study was aimed at evaluating dentin permeability after irrigation with sodium hypochlorite (NaOCl) and final rinse with chlorhexidine (CHX), ethylenediamine tetraacetic acid (EDTA) + CHX, and new combination products: QMiX or MTAD. Methods Roots of 60 maxillary incisors were randomly divided into five groups (n = 12) before instrumentation and irrigation with NaOCl according to the final irrigation regimen: CHX (2% CHX), EDTA + CHX (17% EDTA + 2% CHX), QMiX, MTAD, and control group (distilled water). After final irrigation, ten roots of each group were horizontally sectioned and dye penetration was evaluated in the coronal, middle, and apical thirds. Remaining samples were subjected to scanning electron microscopy. Data were analyzed with ANOVA/Tukey’s test. Results Less dye penetration was found in CHX group compared with control as well as with QMiX and MTAD group in all thirds (p < 0.05). A significant difference between the control and EDTA + CHX, QMiX or MTAD group was observed only in the apical root third (p < 0.05). Conclusion Dentin permeability was significantly reduced after final irrigation with CHX, but not after use of other final irrigation solutions, except in the apical third of the root canal.

    QUALITY OF ROOT CANAL FILLINGS IN A BOSNIAN ADULT POPULATION TREATED IN PUBLIC AND PRIVATE DENTAL CLINICS
    (University of Kragujevac, Faculty of Science, Serbia, 2016) Nogo-Zivanovic, Dajana; Kulic, Ljiljana; Tanaskovic, Irena; Ristic, Vladimir; Kanjevac, Tatjana
    The aim of this study is to examine the technical quality of root canal fillings in an adult population in the Republic of Srpska, Bosnia and Herzegovina, who were treated in public dental institutions and private dental clinics. Radiographs of faculty patients, aged 25-60 years old, who came for the first time were examined for the technical quality of root canal fillings. Patients with endodonticallytreated teeth were invited for an interview to reveal the providers of the endodontic treatment. The percentages of teeth with adequate length (p<0.01) and taper (p<0.01) in institutions of public health cases were significantly greater than those in private clinic cases. In addition, the frequency of teeth with adequate root canal fillings in patients treated in public dental institutions was significantly greater than those treated in private dental clinics (p<0.01). A significantly higher percentage of adequate canal fillings is present in teeth where endodontic treatment was performed in public dental institutions compared to private dental clinics. This result indicates the need to improve the quality of endodontic treatment through more intensive training for dentists in private practice.
