Despite its practical importance in image processing and computer vision, blind blur identification and blind image restoration have so far been addressed under restrictive assumptions such as all-pole stationary image models blurred by zero or minimum-phase point-spread functions. Relying upon diversity (availability of a sufficient number of multiple blurred images), we develop blind FIR blur...
reconstructive techniques through dynamic and static tests. Forty human anterior teeth were divided into 4 groups (n=10): GNW (non-weakened) – root restored with glass fiber post (GFP), GW – weakened root restored with GFP, GDA weakened root restored with direct anatomic GFP, and GIA weakened root restored with indirect anatomic GFP. The teeth were endodontically treated considering that experi...
Statement Problem: A few studies have been conducted about bioglass posts.Aim: The aim of this study was to compare bioglass posts with prefabricated metallic posts in clinical performance of extensive composite restorations for anterior endodontically treated teeth. Materials and Methods: Sixty endodontocally maxillary anterior teeth, with horizontally or vertically destruction, were selected....
Immediate Dentin Sealing or pre-hybridization implies the application of resin adhesive to freshly cut dentin after teeth preparation, before impression. has been suggested as an alternative delayed sealing (DDS), a technique in which is applied just final bonding indirect restorations. universal i.e used inlays, onlays, veneers, crowns and well documented clinically experimentally. Various typ...
The aim of this in vitro study was to compare microleakage of orthodontic brackets between enamel-composite and composite-bracket interfaces at the occlusal and gingival margins, bonded using indirect bonding systems with that of a conventional direct bonding method. Forty freshly extracted human maxillary premolar teeth were randomly divided into two groups. In group 1, the brackets were bonde...
BACKGROUND The ferrule effect in root treated teeth requiring cast posts and cores has been shown to greatly improve fracture resistance. Studies have also shown that in the case of a cast post and core, the longer the ferrule, the greater the fracture resistance. However few studies have considered the effect of different ferrule designs on prefabricated post and composite core systems. AIM ...
introduction: in restorative dentistry, selecting the proper material is an important factor for clinical success. the objective of this study was clinical evaluation of survival time of three tooth color materials in primary anterior teeth. methods: in this interventional clinical trial study, 94 deciduous anterior teeth (36 teeth in boys, 58 teeth in girls) belonging to 3-5 year old children ...
Esthetic restorations always play an important role for emotional and psychological well being of the patient. A beautiful smile quickly radiates excitement, passion, and charisma among the people. The fracture of anterior teeth always becomes cosmetic problem in many cases. Before closing the space, proper diagnosis of the cause, knowing the hope and expectation of patient, available treatment...
This study was carried out to evaluate the microleakage of Class II cavities restored with various types of lining materials. Four types of composite resins (Esthet-X-Denstply, USA, FiltekTMZ350-3M ESPE, USA, BeautifilShofu, Japan and Solare P-GC, Japan) were used and the lining were the Fuji IXGP (GC, Japan), the Beautifil flow (Shofu, Japan), the FiltexTMZ350 flow (3M ESPE, USA) and the Esthe...
statement of problem: the bond strength between restorative material and tooth structure is so important for conduction of durable restoration. considering the recent attention to low shrinkage composite resins, evaluation of micro tensile bond strength of these materials would be valuable. objectives: to compare the microtensile bond strength of silorane composite resin (filtek p90) with the c...
