This study aimed to analyse and compare apical extrusion of debris in canals instrumented with systems used reciprocating continuous motion. Sixty mandibular premolars were randomly divided into 3 groups (n = 20): the Reciproc (REC), WaveOne (WO), HyFlex CM (HYF) groups. One Eppendorf tube per tooth was weighed advance on an analytical balance. The root according manufacturer's instructions, standardised irrigation 2.5% sodium hypochlorite performed a total volume 9 mL. After...
This study aimed to perform a rigorous sample standardization and also evaluate the preparation of mesiobuccal (MB) root canals maxillary molars with severe curvatures using two single-file engine-driven systems (WaveOne reciprocating motion OneShape rotary movement), micro-computed tomography (micro-CT).Ten MB roots single were included, uniformly distributed into groups (n=5). The samples prepared WaveOne or files. shaping ability amount canal transportation assessed by comparison pre-...
The aim of this study was to analyse the potential occurrence dentinal defects after root canal preparation using three engine-driven instruments.Eighty permanent mandibular incisors were selected. Twenty teeth did not undergo preparation, and remaining divided into groups (n=20): Reciproc (REC), ProTaper Next (PTN) WaveOne Gold (WOG). samples dyed with methylene blue, sectioned perpendicularly long axis in 3-, 6- 9-mm slices finally observed under a stereomicroscope (under 25×)....
This study aims to evaluate the frequency of dentinal defects after root canal preparation with ProTaper NEXT, K3XF and WaveOne GOLD systems using microcomputed tomography.Sixty permanent mandibular incisors a single were selected. Inspection teeth was performed under stereomicroscope (15x) observe presence pre-existing cracks fractures lines. Samples divided into three experimental groups (n = 20): NEXT (PTN), (K3XF) (WOG). Specimens scanned through high-resolution tomography before canal....
Abstract This study aimed to analyze the potential occurrence of dentinal defects after removal a root canal filling with two different sealers using Reciproc (RC) or Blue (RB). The mesial roots 60 mandibular molars Vertucci type IV configuration were selected. samples initially instrumented (R25) and then divided into following four experimental groups according endodontic sealer retreatment instrument (n = 15): BC Sealer/Reciproc (BCRC); (BCRB); AH Plus/Reciproc (AHRC); (AHRB). Then,...
The aim of this study was to evaluate the effectiveness a reciprocating single-instrument system (Reciproc-REC) compared with combined continuously rotating multiple-instrument systems [D-Race (DR) and BioRace (BR)] in reducing Enterococcus faecalis (E.f.) after gutta-percha removal.Forty-six extracted human maxillary incisors were prepared contaminated E.f. strain (ATCC 29212) for 30 days. samples obturated randomly divided into two experimental groups removal (n=23): REC group (R50) DR/BR...
The chronology of COVID-19 infections shows us that the first cases were reported in December 2019. A number patients admitted to hospitals with a respiratory disease an unknown etiology Wuhan, Hubei Province, China. presented symptoms such as coughing, persistent fever, sore throat and pneumonia. infection situation got worse rapidly had very fast spread. Soon after, it was causing agent been confirmed novel Coronavirus (SARS-CoV-2), which belongs subfamily Orthocoronavirinae, family...
The aim of this study is to report a case two maxillary incisors with chronic apical abscess and through-and-through lesion submitted periradicular regenerative surgery, clinical follow-ups evaluation through cone-beam computerized tomography for 7 years. In the presentation, there was persistent sinus tract in palate sensibility touch at region central left lateral incisors. initial revealed presence an extensive radiolucent area third referred teeth, loss buccal palatal cortic es. For...
