The most frequent reason for failure of laminate veneers made of glass ceramics (feldspathic, leucite based and lithium silicate based ceramics) was fracture of the ceramic, Therefore, ceramic materials that have higher fracture resistance, especially for patients suffering from abnormal occlusion, are needed.

When restoring teeth with IPS Empress laminate veneers, fracture of restorations may occur. So, material with higher mechanical properties is required. Celtra Duo is a new material with gl...
The purpose of this study was to compare the whitening effect of a toothpaste containing blue pigment with a conventional toothpaste and with at-home tooth bleaching; evaluate the subject'...
This investigation will be a clinical trial to study the performance of a newly developed high strength ceramic material for crowns. The ceramic has been approved by the FDA for patient tr...
- To evaluate and compare the degree of tooth discoloration in tooth crowns induced by Neo MTA versus white MTA over time. - Evaluation of the effectiveness of Neo MTA as coronal...
The purpose of this clinical study was to evaluate, the effectiveness and sensitivity post-treatment of a 6% hydrogen peroxide with nitrogen-doped titanium dioxide light activated bleachin...
Fabricating a ceramic restoration for a discolored anterior tooth presents a clinical challenge. The dental technician is often hampered by being unaware of the shade of the discolored tooth preparati...
Because orthodontic tooth movement is dependent upon osteoclast-mediated resorption of alveolar bone adjacent to the pressure side of tooth roots, biologic mediators that regulate osteoclasts can be u...
This manuscript summarises the reasons behind choosing indirect restorations in the treatment of tooth wear. The purpose of this article is to discuss the use of crowns as a restorative treatment opti...
Tooth loss is a significant health issue currently affecting millions of people worldwide. Artificial dental implants, the current gold standard tooth replacement therapy, do not exhibit many properti...
This case series describes a treatment method in which the natural tooth was used as the temporary and permanent reconstruction after immediate implantation in the esthetic zone of periodontally compr...
Any change in the hue, color, or translucency of a tooth due to any cause. Restorative filling materials, drugs (both topical and systemic), pulpal necrosis, or hemorrhage may be responsible. (Jablonski, Dictionary of Dentistry, 1992, p253)
The pathologic wearing away of the tooth substance by brushing, bruxism, clenching, and other mechanical causes. It is differentiated from TOOTH ATTRITION in that this type of wearing away is the result of tooth-to-tooth contact, as in mastication, occurring only on the occlusal, incisal, and proximal surfaces. It differs also from TOOTH EROSION, the progressive loss of the hard substance of a tooth by chemical processes not involving bacterial action. (From Jablonski, Dictionary of Dentistry, 1992, p2)
The wearing away of a tooth as a result of tooth-to-tooth contact, as in mastication, occurring only on the occlusal, incisal, and proximal surfaces. It is chiefly associated with aging. It is differentiated from TOOTH ABRASION (the pathologic wearing away of the tooth substance by friction, as brushing, bruxism, clenching, and other mechanical causes) and from TOOTH EROSION (the loss of substance caused by chemical action without bacterial action). (Jablonski, Dictionary of Dentistry, 1992, p86)
Mechanical removal of a small amount of tooth structure (not more than a few tenths of a millimeter in depth) to eliminate superficial enamel discoloration defects not successfully removed by bleaching techniques. A common abrasive is a mixture of pumice and hydrochloric acid.
The upper part of the tooth, which joins the lower part of the tooth (TOOTH ROOT) at the cervix (TOOTH CERVIX) at a line called the cementoenamel junction. The entire surface of the crown is covered with enamel which is thicker at the extremity and becomes progressively thinner toward the cervix. (From Jablonski, Dictionary of Dentistry, 1992, p216)
Osteoporosis is a disease in which the bones become extremely porous, are subject to fracture, and heal slowly, occurring especially in women following menopause and often leading to curvature of the spine from vertebral collapse. Follow and track&n...
