Loss of anterior tooth causes aesthetic and functional disharmony. Although no restorative material can approach the appearance of intact tooth enamel, glass ceramic, at the increased risk of brittle fracture, can mimic original tooth color better than the other restorative options. The newest zirconia material comes with unparalleled individualization in aesthetics and optimal physical propert...

The purpose of this study was to evaluate cuspal flexure in posterior primary teeth following restoration with three different materials. Twelve primary second molars were obtained. A precision strain gage was attached to the buccal surface of each tooth and balanced at zero. The teeth were mounted and then loaded with a 10 kg force; the strain appearing on the strain gage indicator was recorde...

Reattachment of tooth fragment is a simple, conservative, and noninvasive procedure, and it is the most currently acceptable treatment option. This article presents management of two accidentally damaged maxillary incisors using direct composite resin restoration and fractured tooth fragment. With the advancements in adhesive dentistry, tooth fragment reattachment procedure has become simpler a...

When an abutment tooth is endodontically treated and is intact except for the access opening, the amount of tooth structure remaining after tooth preparation must be carefully assessed. If only a thin peripheral shell of tooth remains after reduction (which occurs frequently in incisors, canines and premolars), a cast post and core should be fabricated. In this article, the use of a prefabricat...

Restoration of endodontically treated teeth is one the major challenges faced in field operative dentistry. In tooth, most part tooth structure lost because dental caries, conventional access cavity preparation and biomechanical during root canal therapy. They become very weak brittle also more prone to fracture compared vital

There are at least two different techniques for preparing teeth prior to bonded porcelain restorations. The first involves using depth cutters guided by the existing tooth structure. A more recently developed approach integrates an additive wax-up that represents the final volume of the teeth, with indices used to guide the preparation design. This article illustrates in detail a clinical case ...

introduction: the purpose of this study was to evaluate external root surface temperature rise during post space preparation using la axxess bur, beefill pack system, and peeso reamer drill. materials & methods: the distal canals of forty-five extracted human permanent mandibular first molars were instrumented in crown-apical manner and obturated with lateral condensation technique. teeth were ...
