The mean ± SD maximum RSS recorded with XPS and HCM were 165.71 ± 86.57, and 132.14 ± 97.26 respectively with no statistical difference between them (p>0.05). Post-instrumentation microcracks were observed in only two canals prepared by XPS (10%) versus one canal prepared by HCM (5%), and this difference was also statistically non-significant (P>0.05). The inter-evaluator reliability for microcrack detection using ESEM had a Kappa value of 0.98 (p<0.001), while the intra-evaluator reliability had a Kappa value of 0.99 (p<0.001). The maximum RSS obtained during canal shaping was poorly correlated with the number of microcracks found (R2=0.090). \u0000Results: Increased baseline RSS from strain accumulation during canal shaping was observed in both groups.

The maximum RSS obtained during canal shaping was poorly correlated with the number of microcracks found (R2=0.090). \u0000Conclusions: Within the limitations of this study, canal shaping by the two systems was confirmed to strain the tooth structure. However, the measured RSS was poorly correlated with the development of apical microcracks.

A treatment option for young permanent teeth with necrotic pulps is pulp regeneration, whose advantage lies in the stimulation of new tissue formation within the root canal. Pulp revascularization is based on the disinfection of the root canal system, often performed with irrigating solutions and intracanal medicaments, accompanied by induction of periapical bleeding and formation of a blood clot that will fill the root canal.

Thus, new agents that effectively eliminate endodontic pathogens are needed. The aim of this study was to assess the antibacterial properties of two synthetic peptides, namely KP and L18R, against planktonic cells and biofilms of the endodontic pathogen Enterococcus faecalis. \u0000Methodology:KP and L18R bactericidal activity against E. faecalisATCC 29212 was evaluated by colony forming unit assays and the half maximal effective concentration (EC50) was calculated. The effect of peptides on E. faecalis biofilm formation onto polystyrene plates was also assessed by the crystal violet assay. Confocal laser scanning microscopy (CLSM) analysis was carried out to compare the effects of KP, L18R, and a Ca(OH)2saturated solution in an in vitro model of dental infection consisting in 2-day-old E. faecalisbiofilms grown on hydroxyapatite disks. \u0000Results: Both KP and L18R showed strong bactericidal activity against planktonic E. faecalis. L18R proved to be 10-folds more effective than KP (KP and L18R EC50values = 4.520 × 10‑6 Mand 3.624 × 10-7 M, respectively). Peptides inhibited E. faecalis biofilm formation in a dose-dependent manner and L18R resulted more effective than KP.CLSM images showed that Ca(OH)2, KP and L18R remarkably impaired E. faecalis biofilms pre-grown on hydroxyapatite. \u0000Conclusions: KP and L18R effectively inhibited E. faecalis, both in planktonic and biofilm form. L18R demonstrated a more potent antibacterial activity than KP. These preliminary results suggest that antimicrobial peptides may represent a promising new strategy for endodontic infection control.","PeriodicalId":42221,"journal":{"name":"Giornale Italiano di Endodonzia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89039367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Glide path was performed with ProGlider and shaping with ProTaper Next (PTN) X1, X2 and X3 up to working length (WL). The specimens were randomly divided into three groups (N=10) for the final 3D filling step: Buchanan’s continuous wave of condensation (Group 1, G1), Thermafil® (Group 2, G2) or TotalFill® BC Points™ combined with TotalFill® BC Sealer (Group 3, G3). \u0000Micro-CT scans were performed after the obturation step and the slices were 3D reconstructed with standardized parameters. Afterwards, the filled area and the associated radiographic translucencies were computer-isolated, and their volumes were calculated. The statistical analysis was performed using one-way ANOVA and the post-hoc Student-Newmann-Keuls (P<0,05). \u0000Results: The mean percentage of translucency areas in the warm vertical condensation group was 1,23%, whereas in the carrier-based group was 4,22% and in the single cone with bioceramic sealer group was 10,44%.

Canals were filled with organic paste to simulate the organic pulp tissues. With both devices, irrigation was performed using 5% sodium hypoclorite and two activation times of 30 seconds each. Sodium hypochlorite was replaced every 30 seconds. After a photographic exam, debris removal was evaluated by a software and assessed in terms of percentage of cleaned canal.

The duration of using ultrasonic vibrations (and the number of surfaces where the vibration was applied) led to less time spent and less force needed to dislodge a metal post. Dentist’s expertise (more than 10 years) was also related to easier post removal.
