CASE I (Courtesy of Dr. A. Peschke)

Tooth with broken edge

Tooth with broken edge- A front tooth with broken edge. The fracture is confined to enamel. The dentist has cut the enamel and created "a scalloped bevel". The tooth is then treated (etched) with a special acid, before the adhesive and restorative material (composite resin) are placed.

 

Final restoration made with composite resin.

Tooth Slice

Tooth Slice

Tooth Slice- The tooth is made out of a very hard and brittle outer shell called ENAMEL. It is mainly inorganic containing 96% hydroxyapatite crystals. The enamel is firmly bonded to the inner part, called DENTIN, which is an organic/inorganic composite (30% collagen, 50% hydroxyapatite, 20% water). Dentin is a vital tissue since it contains string-like processes from the cells lining the dentin in its inner surface (odontoblasts). The center of the tooth (white and black in picture) is filled with living tissue (connective tissue, blood vessels and nerve fibers). Courtesy of Dr. A. Peschke.

Patient presents himself with old, discolored large restorations and fractures.

The operative field is insulated from the oral cavity to prevent contamination of the adhesive interfaces. The old restorations are removed and bevels placed.
