objectives: repairing composite restorations is a challenging procedure especially when two different types of composites are used. this study aimed to compare the repair strength of silorane-based composite (sc) (filtek p90) with that of preheated sc, methacrylate composite (mc)(z250), flowable mc (filtek supreme plus) and different adhesive/composite combinations. materials and methods : eigh...
objective: selection of an appropriate shade of composite is critical in achieving an esthetic restoration. different systems are used to assess and describe color parameters. this study aimed to assess the effect of color and thickness of filtek supreme (fs) and premise (p) composite resins on correction of tooth discoloration. methods: in this in vitro experimental study, 10 anterior teeth ...
With conventional fixed dental prostheses, the interim restoration is a valuable diagnostic tool in the evaluation of esthetics and function. To achieve predictable definitive esthetic results, information about the subgingival and the supragingival contour of a properly designed restoration should be communicated to the dental laboratory technician. The technique described enables the accurate...
1. Discusses the properties of enamel and dentin and their role in adhesive dental restoration;2. Chapters also examine the wear properties of dental ceramics, glasses and bioactive glass ceramics for tooth repair and replacement;3. Dental composites and antibacterial restorative materials are also considered;4. Provides a concise overview of non-metallic biomaterials for dental clinicians, mat...
In literature, the primary function of a dental cement is to fill the space between restorative material (definitive or provisional) and tooth preparation (or implant abutment), as well as to enhance the resistance to restoration dislodgement during function [1,2]. Of utmost importance, the long-term success of a restoration is heavily dependent on the proper selection and manipulation of denta...
We have used synchrotron x-ray diffraction to study the crystal orientation in human dental enamel as a function of position within intact tooth sections. Keeping tooth sections intact has allowed us to construct 2D and 3D spatial distribution maps of the magnitude and orientation of texture in dental enamel. We have found that the enamel crystallites are most highly aligned at the expected occ...
AIM The purpose of this study was to assess the knowledge, attitude, and practice of dental implantology among dentists practicing in Nigeria. MATERIALS Self-administered questionnaires to assess the knowledge, practice, and attitude of dental implantology were sent to dentists practicing in all the 6 geopolitical zones of Nigeria (i.e., all tertiary dental institutions, and selected general ...
objective: there is no definitive data on the strength of glass fiber and cast posts with different length. this in vitro study was designed to investigate and compare the effect of length on the retentive strength of glass fiber and cast posts. materials and methods: sixty recently extracted intact maxillary canine teeth were cut 1mm above the cej. the specimens were endodontically treated and...
The objective of this study is to share cost analysis methodology and to obtain cost estimates for posterior restorations in public sector dental clinics. Two urban and 2 rural dental clinics in Selangor state were selected. Only cases of 1 posterior restoration per visit by dental officers were included over 6 months. One capsulated amalgam type, 1 capsulated tooth-colored, and 1 non-capsulate...
