PURPOSE To investigate the sealing properties of root fillings with resin-coated gutta-percha cones and a methacrylate-based resin endodontic sealer with and without an accelerator component in root canals subjected to immediate or delayed post space preparation. METHODS Forty-eight extracted human teeth with single straight root canals were treated endodontically. Specimens were then assigne...

Objectives To examine the surface topography of intact WaveOne (WO; Dentsply Sirona Endodontics) and WaveOne Gold (WOG; Dentsply Sirona Endodontics) nickel-titanium rotary files and to evaluate the presence of alterations to the surface topography after root canal preparations of severely curved root canals in molar teeth. Materials and Methods Forty-eight severely curved canals of extracted ...

BACKGROUND We have previously reported on the variation of total fructooligosaccharides (FOS), total inulooligosaccharides (IOS) and inulin in the roots of burdock stored at different temperatures. During storage at 0°C, an increase of FOS as a result of the hydrolysis of inulin was observed. Moreover, we suggested that an increase of IOS would likely be due to the synthesis of the IOS by fruct...

The paper considers the possibilities of using vegetable raw materials - burdock root flour with addition psyllium and a gluten-free mixture in manufacture enriched bread, their influence on quality indicators obtained samples. To achieve this goal samples introduction various concentrations from containing seed husk, were studied. Flour was added amount 5-15% by weight directly replacement dur...

Successful Endodontic treatment depends upon Adequate knowledge about the morphology of root canal system and diagnosing the anatomic variants to avoid missed canals. Maxillary second molars usually present with two buccal and one palatal root. Occurrence of an extra palatal root is a rare scenario with prevalence of around 1.4%.. The following case report describes endodontic management of max...

External root resorption was recognized as a late complication of traumatic injuries to the teeth, which usually occurs after orthodontic treatment, orthognatic or dentoalveolar surgery, bleaching techniques or other similar conditions. The purpose of our paper is to discuss the predisposing factors and to present treatment options for teeth with cervical resorption, with emphasys on surgical e...

OBJECTIVE The aim of this study was to compare the fracture resistance of roots obturated with different materials. STUDY DESIGN Sixty root canals were instrumented and divided into 4 equal groups (n = 15 each). The root canals in group 1 were filled with AH26 sealer and gutta-percha, in group 2 with Resilon and Epiphany, and in group 3 with Ketac-Endo Aplicap and gutta-percha. Fifteen root c...
