Objective: To investigate the influence of sonic agitation or laser-activated irrigation techniques on the removal chlorhexidine (CHX) and modified triple antibiotic paste (mTAP) on the sealer penetration depth and dislocation resistance of Guttaflow Bioseal. Methods: Single-rooted mandibular premolars (n=96) were prepared with rotary nickel titanium instruments and randomly divided into two groups (n=48) based on the intracanal medicaments used: Group 1, mTAP; Group 2, CHX gel. After 7 days, the specimens in each group were divided into three subgroups (n=16) based on the supplementary irrigation technique used to remove the medicaments: laser activated irrigation (Er, Cr: YSGG laser, Waterlase MD, Biolase Technology Inc., San Clemente, CA, USA), sonic agitation (EndoActivator, Dentslpy Sirona Endodontics, PA, USA) and syringe-and-needle irrigation (control) techniques. Canals were filled with single matched-taper gutta-percha cone and a calcium silicate-based sealer (GuttaFlow® Bioseal, Coltène/Whaledent, Langenau, Germany). At the end of three weeks, sealer penetration was investigated using confocal microscopy (n=6), and dislocation resistance was calculated by measuring the push-out bond strength (n=10). Statistical analysis was performed using three-way analysis of variance (ANOVA) and Tukey post-hoc test (P=0.05). Results: Laser activated irrigation resulted in significantly higher depth of sealer penetration compared to sonic agitation and syringe irrigation (P<0.01). The average sealer penetration depths were recorded as 846.6 µm, 786.5 µm and 505 µm in the Er, Cr: YSGG laser, EndoActivator and control groups, respectively. The mean bond strength obtained in group 3 (syringe-and-needle irrigation) was significantly less than the other groups (P<0.05). The mean values were 9.08 in the Er, Cr: YSGG laser group, 8.44 in the EndoActivator group and 5.08 in the needle group. Conclusion: Er,Cr;YSGG laser irrigation to remove the medicaments was advantageous to other irrigation techniques in sealer penetration and dislocation resistance of the sealer.
Aim: This review examines the studies on resin composites within the past decade and evaluates the materials’ application methods and success through Fédération Dentaire Internationale (FDI) scores. Materials and Methods: Search results from three databases (a total of 3295 studies) were transferred to Mendeley Desktop (Mendeley, London, UK) software and deduplicated (2638 studies). Eight studies were included in this meta-analysis after scanning the title, abstract, and full-text screening. Risk of bias analysis was performed using the Cochrane Handbook tool. Shapiro–Wilk, Kolmogorov–Smirnov, Kruskal–Wallis, and post hoc Tamhane’s T2 were used for statistical analysis. Results: Conventional composite’s surface staining FDI score was higher than flowable and silorane composites (no difference between these two). Also, conventional composite has the highest score in terms of staining. Conventional composite + two-step self-etch adhesive and bulk fill composite + two-step self-etch adhesive have lower FDI scores in marginal staining. In noncarious cervical lesions (NCCL), conventional composite + two-step total-etch adhesive has a higher score than flowable composite + two-step self-etch adhesive. Flowable composite + two-step self-etch adhesive and conventional composite + single-step self-etch adhesive have the highest FDI scores for marginal adaptation (no statistical difference between them). Conventional composite + two-step self-etch adhesive and bulk fill composite + two-step self-etch have the lowest scores (no statistical difference between them). For recurrence of caries, all groups have Score 1, the best score, and there is no significant difference between them. Conclusions: Each restorative material and adhesive system has different advantages, and the practitioner must choose the most appropriate.
ABSTRACT:Biomedical applications generally needs measurement the human body parts in motion. On the other hand, the analysis of the human motion includes mobile measurements. The mobile measurement is complicated task because it needs two or more sensor combination, specific measurement techniques and huge computation. Thus, it is actual research topic in photogrammetry and computer sciences community. Time-of-flight (ToF) camera can make measurement the moving object. It can be used for robotic and simultaneous localization and mapping applications. Human motion capture is recent application area for ToF camera. In this study analysis of the body motion were made with time-of-flight camera. We made measurement to runner on treadmill. The motion was analysed with computing the angle between body parts.
