This is a list of definitions of commonly used terms of location and direction in dentistry. This set of terms provides orientation within the oral cavity, much as anatomical terms of location provide orientation throughout the body. Most of the principal terms can be combined using their corresponding combining forms such as mesio- for mesial and disto- for distal. They provide names for directions vectors and axes; for example, the coronoapical axis is the long axis of a tooth. Such combining yields terms such as those in the following list.
Purpose: To evaluate the effect of direction of first cure and the presence or absence of a facial margin bevel on the adaptation of facial margins of Class III resin-based composite RBC restorations. Materials and methods: Custom polyvinyl siloxane PVS light shields were fabricated for both the mesial and distal surfaces of 20 extracted incisors. Class III cavities were prepared in the mesial and distal surfaces of the incisors. On the facial, lingual, and gingival margins of 20 of the preparations a 0. The lingual and gingival, but not the facial, margins were beveled on the other 20 preparations. The PVS light shield was adapted to the tooth and trimmed to allow mm of the facial margin to be exposed on 10 of the beveled and 10 of the non-beveled preparations. For the remaining 20 preparations the PVS light shield was trimmed to allow access of the curing light only from the lingual.
Smile Form. Tooth Structure. Composite bonding and esthetic recontouring produce a nice smile. Composite diastema closure is performed on the mesial of the central incisors combined with esthetic recontouring of the distal embrasures and line angles. Composite is bonded to the mesial of the lateral incisors to form and improved silhouettes and faces of these teeth.
