Evaluation of porous asphalt hydrological performances through rainfall-runoff modelling by EPA SWMM
2023
Over the last few decades, the increase in extreme weather events has caused urban floods to become more and more frequent, with increased risks for road users. Among the different types of pavement structures, permeable pavements (PPs) can effectively increase the hydraulic resilience of the cities since they are specifically designed for reducing runoff by allowing water to infiltrate and be discharged into the soil and/or by drains. This study aims at evaluating the hydrological performance of a Porous Asphalt (PA) using numerical simulations for a case study carried out using EPA SWMM (Storm Water Management Model) software. Several simulations have been carried out, considering differe…
Efficacy of removing Thermafil and GuttaCore from straight root canal systems using a novel non-surgical root canal re-treatment system : a micro-com…
2021
The present study aims to evaluate the effectiveness of an XP-endo non-surgical root canal re-treatment system in removing both GuttaCore and Thermafil gutta-percha carrier-based root canal filling materials from straight root canal systems using micro-computed tomography (micro-CT) analysis. The study was performed on 20 single-rooted upper teeth, which were randomly allocated into the following study groups: Group A, Thermafil and AH Plus sealer (n = 10)
Er:YAG laser in defocused mode for scaling of periodontally involved root surfaces: An in vitro pilot study
2005
Item does not contain fulltext BACKGROUND: The Er:YAG laser may be used on periodontally involved teeth in combination with conventional periodontal therapy in order to improve the efficacy of root instrumentation. The aim of this study was to compare the effect of hand instrumentation on root surfaces of periodontally involved teeth with Er:YAG laser application. METHODS: Thirty freshly extracted, non-carious, single-rooted, periodontally diseased human teeth from adult humans with advanced periodontal disease were used in this study. The teeth were divided into three groups of 10 specimens each. Group A was treated with scaling and root planing (SRP) with curets only (control). In group B…
Non-surgical periodontal treatment with a new ultrasonic device (Vectortm-ultrasonic system) or hand instruments. A prospective, controlled clinical …
2004
Objectives: The aim of this prospective, randomized, controlled clinical study was to compare the effectiveness of a newly developed ultrasonic device to that of scaling and root planing for non-surgical periodontal treatment. Material and Methods: Thirty-eight patients with moderate to advanced chronic periodontal disease were treated according to an “one-stage procedure” with either a newly developed ultrasonic device (VUS) (Vector™-ultrasonic system) or scaling and root planing (SRP) using hand instruments. Clinical assessments by plaque index (PlI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), gingival recession (GR), and clinical attachment level (CAL) were made …
Influence of systemic strontium ranelate on the progression and as adjunctive therapy for the nonsurgical treatment of experimental periodontitis
2021
Made available in DSpace on 2022-05-01T11:39:06Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01 Universidade Estadual Paulista Background: Strontium Ranelate (SR) presents overlapping osteoanabolic and anti-resorptive activity. However, the effects of SR on the progression of periodontitis through the alveolar bone and its potential applicability as adjunctive therapy to scaling and root planning remain poorly accessed. The aim of this study was to evaluate the effects of systemic (SR) both on the progression of experimental periodontitis (EP) and as adjunctive therapy to SRP. Material and Methods: Eighty male rats were divided into four groups (n=20): EP-PSS: EP induction and …
Evaluation of ergonomics and efficacy of instruments in dentistry
2013
Abstract: Purpose: To evaluate the ergonomics and efficacy of five instruments used in dentistry for scaling and root planing. Methods: This experimental study with a comparative cross-sectional design was carried out during a simulated scaling and root planing task. Seven female dentists and one dental hygienist aged 26–58 years participated. Five instruments were evaluated in a subjective analysis of usability and musculoskeletal strain and with measurements of muscular activity, postures of the upper limbs, and work productivity. Results: The instruments with the thickest (diameter of 12–14 mm) silicon handles caused the lowest perceived strain in both the fingers/palm and the thumb. Wor…
The influence of NiTi alloy on the cyclic fatigue resistance of endodontic files
2020
Background: The aim of this study was to analyze the influence of NiTi alloy in endodontic rotary instruments on cyclic fatigue resistance. Methods: One hundred and sixty-four (164) sterile endodontic rotary files were selected and distributed into the following study groups: A: 25.08 F2 ProTaper Universal (PTU) (n = 41)
The Efficacy of Rotary, Reciprocating, and Combined Non-Surgical Endodontic Retreatment Techniques in Removing a Carrier-Based Root Canal Filling Mat…
2020
The aim of this study is to analyze and compare the efficacy of three non-surgical endodontic retreatment techniques in removing a carrier-based root canal filling material from straight root canal systems. The study was performed on 99 single-rooted extracted teeth using the ProTaper Gold endodontic rotary system up to the F2 file (Dentsply Maillefer, Baillagues, Switzerland), which were sealed with GuttaCore (Dentsply Maillefer, Ballaigues, Switzerland) and AH plus epoxy resin sealer (Dentsply DeTrey, Konstanz, Germany) and randomly assigned to the following non-surgical retreatment techniques: ProTaper Retreatment endodontic rotary instruments (D1&ndash
Les thermes, le ski, et puis la nuit. Des stations illuminées à la valorisation des ressources environnementales nocturnes dans les territoires touri…
2015
International audience; Les réflexion engagées par le Collectif RENOIR interrogent le devenir des territoires touristiques au regard d’un processus émergent : la considération de la nuit et du paysage nocturne dans les projets de territoires. La mise en scène de ce que nous appelons des « ressources environnementales nocturnes » est appréhendée comme point de départ pour l’observation des stations touristiques en transition.Ce processus s’accompagne de mutations profondes, qui trouvent leurs sources dans la remise en cause d’un éclairage urbain (monumental, de voirie, de sécurisation, etc.) focalisé, jusque dans les années 1980, sur des aspects quantitatifs. Les différentes fonctions de l’é…
