Three-year clinical performance of two indirect composite inlays compared to direct composite restorations
2013
Objective: Despite the incremental build-up of resin composite restorations, their polymerization shrinkage during curing presents a serious problem. Indirect composite resin systems represent an alternative in overcoming some of the deficiencies of direct composite restorations. The hypothesis of the present study states that the clinical performance of restorations may be affected by different generation and application techniques. Study Design: Sixty restorations (20 DI system (Coltene/Whaledent AG, Altstatten, Switzerland) composite inlays, 20 Tescera ATL system (BISCO Inc. Schaumburg, Illinois, USA) composite inlays, and 20 direct composites) were applied to premolar teeth in 49 patien…
Lichenoid lesions of the upper lip: A retrospective study of 24 cases.
2017
Background Lichenoid lesions of the upper labial mucosa, without other oral or extraoral manifestations seem to be rare. The clinicopathologic features of 24 such cases are presented and the pertinent literature is reviewed. Material and Methods 24 Caucasian patients that clinically presented lichenoid features on the upper labial mucosa, with or without lichenoid lesions on the adjacent gingiva, were included in the study. Clinical features were extracted from the patients’ records, while dental plaque/calculus accumulation and composite resin restorations of the adjacent teeth were recorded. Four cases where an incisional biopsy was performed were further evaluated. Results There were 8 m…
Rehabilitation of the severely atrophied dentoalveolar ridge in the aesthetic region with corticocancellous grafts from the iliac crest and dental im…
2016
Background The aim of this study was to assess changes in bone volume after block bone augmentation and placement of dental implants and further evaluate the aesthetic outcome of the treatment. Material and Methods 9 Patients with atrophied anterior maxilla were included in this study. They received total of 21 implants. Dimensions of the alveolar ridge were measured from cone-beam computed tomography x-rays. The bone level at the implant sites was analysed from intraoral x-rays and the aesthetic outcome was assessed from clinical photographs using a pink aesthetic score (PES) scaling. Results The mean gained horizontal bone width at the marginal crest and 5 mm apically was accordingly 2.7m…
Effect of 2% Chlorhexidine Following Acid Etching on Microtensile Bond Strength of Resin Restorations: A Meta-Analysis.
2019
Background and Objectives: The aim of this systematic review was to examine the effect of 2% chlorhexidine following acid etching on the microtensile bond strength of resin restorations for different follow-up times. Materials and Methods: A thorough search of PubMed, Scopus, and Embase databases were conducted. In vitro experimental studies or in vivo studies published up to December 2018 with an experimental group treated with a 2% chlorhexidine solution following acid etching and a control group were included, wherein the final restoration used a resin composite in both the groups. Results: Twenty-one articles were identified for qualitative analysis and 18 for meta-analysis. The differe…
Leakage in root canal system during and after treatment: A review
2017
During and after a canal treatment any ingress of germs in the pulp space should be avoid because they are responsible for pulpal and periradicular diseases. Often this treatment is performed in more than one visit and amongst those visits a temporary restoration should impede the re-infection. Initially a pre-treatment (build-up) is required in order to prevent fluid leakage and allow a better isolation by rubber dam and a stabilised clamp. Several restorative materials are on the market and a correct choice is crucial to avoid failure considering several factors such as canal dressing medication, number of day between visits, extension of restoration, occlusal load, presence of parafuncti…
Indagine composizionale sulle pitture di due vasi di Centuripe
2019
Due vasi Centuripe a Palermo sono stati analizzati utilizzando XRF portatile complementare e FTIR a riflessione totale spettroscopie. Le analisi consentono di chiarire la tavolozza e la tecnica della decorazione (pittura a tempera con un legante organico), e mostrano la presenza di pigmenti sia antichi che moderni (a causa di qualche recente riverniciatura). Uno dei risultati più interessanti è stata l'identificazione di due fasi del solfato di calcio nello strato sottostante i dipinti: a causa delle condizioni che trasformano il gesso in bassanite, la presenza di il gesso o, in alternativa, la bassanite in ciascuna parte analizzata possono rappresentare un criterio per distinguere l'origin…
Fracture Resistance of Partial Indirect Restorations Made With CAD/CAM Technology. A Systematic Review and Meta-analysis
2019
Background: The aim of this systematic review and meta-analysis was to determine the fracture resistance and survival rate of partial indirect restorations inlays, onlays, and overlays fabricated using computer-aided design and computer-aided manufacturing (CAD-CAM) technology from ceramics, composite resin, resin nanoceramic, or hybrid ceramic and to analyze the influence of proximal box elevation on fracture resistance. Materials and methods: This systematic review was based on guidelines proposed by the preferred reporting items for systematic reviews and meta-analyses (PRISMA). An electronic search was conducted in databases US National Library of Medicine National Institutes of Health …
Entre destructions et reconstructions, le patrimoine sicilien pendant et après la Seconde Guerre mondiale
2020
Dans cette contribution, nous présentons les traces sur le terrain et dans les archives d’un bombardement survenu à Solonte dans la nuit du 12 décembre 1942. Le point de départ de cette recherche est une photographie conservée dans les archives du Musée archéologique régional Antonio Salinas, documentant la restauration d’une citerne de Solonte suite aux bombardements alliés. Nos recherches dans les archives ont permis de reconstituer la chronologie des faits et de mettre en lumière le rôle des Surintendants des Antiquités de la Sicile occidentale, Jole Bovio Marconi puis Vincenzo Tusa, pendant et après la guerre pour protéger le patrimoine culturel. Solonte, comme d’autres sites siciliens,…
Fracture strenght and ribbond fibers: In vitro analysis of mod restorations
2023
Ribbond fibers are supposed to be a reinforcing material in restoration of compromised teeth. This study aims to compare MOD restorations with and without Ribbond Fiber in terms of fracture strength under axial loading; to identify the minimum depth of MO
Traction test of temporary dental cements
2017
Background Classic self-curing temporary cements obstruct the translucence of provisional restorations. New dual-cure esthetic temporary cements need investigation and comparison with classic cements to ensure that they are equally retentive and provide adequate translucence. The objective is to analyze by means of traction testing in a in vitro study the retention of five temporary cements. Material and methods Ten molars were prepared and ten provisional resin restorations were fabricated using CAD-CAM technology (n=10). Five temporary cements were selected: self-curing temporary cements, Dycal (D), Temp Bond (TB), Temp Bond Non Eugenol (TBNE); dual-curing esthetic cements Temp Bond Clear…
