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 ...

Tooth wear is generally an age-related phenomenon, often assumed to occur at similar rates within populations of primates and other mammals, and has been suggested as a correlate of reduced offspring survival among wild lemurs. Few long-term wild studies have combined detailed study of primate behavior and ecology with dental analyses. Here, we present data on dental wear and tooth loss in olde...

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...

PURPOSE Using a population-based sample of the cross-sectional epidemiologic "Study of Health in Pomerania" (SHIP), this study evaluated whether certain occlusal and sociodemographic factors besides age and gender are risk factors for high dental wear. MATERIALS AND METHODS Medical history and dental and sociodemographic parameters of 2,529 dentate subjects selected representatively and accor...

The aim of this work was to study the wear affecting the almost complete dentition of a Sao individual fossil from Cameroon prehistory (XIVth century). Occlusal surfaces of the fossil fragile pieces were plaster replicated with an original technique adapted from usual dental impression methods (silicon elastomer polymerising by addition). Axial macro-photographs of both sectional dental casts a...

Tooth wear (attrition, erosion and abrasion) is perceived internationally as a growing problem .The loss of tooth substance at the cementoenamel junction because of causes other than dental caries has been identified as non-carious cervical lesions (NCCLs) or cervical wear. NCCLs can lead to hypersensitivity, plaque retention, pulpal involvement, root fracture and aesthetic problems. Hence stud...

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...

Recent research demonstrates that silica phytoliths of dietary origin are associated with microwear of human teeth. Previous research has shown that severe enamel microwear and dental wear characterizes Archaic hunter-gatherers in the lower Pecos region of west Texas. Calcium oxalate crystals are especially common in Archaic coprolites. The vast majority are derived from prickly pear and agave,...

Objective: The aim of the present study was to evaluate the effects of the hard plate used for the treatment of bruxism, on the growth of the alveolar base of the maxillary bone during a 6 month period. Methods: All the subjects were three to six year old, were healthy and presented dental wear. The children were included as bruxist when their anxiety level was above 0.75%, according to Conners...
