This in vitro study evaluates the marginal sealing ability of three different flowable composite systems at enamel and dentin margins, using sealants. Class V preparations were made on the facial surfaces in enamel and dentin/cement of 60 freshly extracted teeth, which were allotted randomly into six groups of ten. The control groups (I, II, and III) showed leakage in the majority of cases. However, Groups IV and V had very limited microleakage scores (2 of 30) in comparison to Group VI (p < 0.001, Mann-Whitney Test)

Diagnosing periodontal diseases involves determining the classification of the disease and the recognition of disease severity at the time of the clinical examination. Traditional diagnostic methods, such as radiographs and periodontal probing, have several limitations. Newer diagnostic techniques have been developed that could help determine whether specific sites are actively breaking down or if the site will experience future active disease. The newest technique is a genetic susceptibility test to identify patients who are at an increased risk for periodontal disease before problems develop. The screening of at-risk patients after initial therapy with these newly developed monitoring tests may lead to improved treatment and prevention of periodontal disease

Ceramic materials provide an alternative when choosing a tooth-colored restoration. Currently, posterior composite restorations can be used to achieve esthetic restorations; however, they have many disadvantages with regard to wear, polymerization shrinkage, discoloration, marginal leakage, and technique sensitivity. The use of CEREC CAD/CAM enables the dentist to place feldspathic porcelain (Vitablocs Mark II) and machinable glass ceramic (Dicor MGC) restorations in a single visit. When compared to composite materials, these materials closely approximate the physical properties of enamel in compressive and tensile strength and wear resistance. This study evaluated 50 CEREC CAD/CAM restorations after 4 years in service. Restorations ranged from Class I to 7/8s crown preparations

This article describes the fabrication of two fiber-reinforced poly-glass ceramic three-unit fixed prostheses. A second-generation laboratory-processed polymer-glass ceramic material (Sculpture) that utilizes a resin-impregnated translucent fiber framework (Fiberkor) was used to fabricate two fixed resin-bonded prostheses. The abutment teeth of one appliance required the use of a full coverage preparation and an inlay design. The other prosthesis required an inlay preparation and onlay configuration. Two three-unit provisional prostheses were fabricated and inserted using eugenol-free temporary cement. With the fabrication of the fixed appliances, they were bonded to the abutment teeth with resin cement. The insertion of the two fixed appliances using the polymer-glass ceramic material provided the esthetic advantage of translucency, while avoiding the appearance of metal
