Diagnostically Based Protocol for Tooth Preparation

Histological preparation of teeth and tooth growth

Background: Traditional techniques for preparation of teeth for histological analysis include: 1) Ground section of non-decalcified tooth and view by polarized light. 2) Decalcify the tooth and then section and stain as per soft tissue. 3) Cryomicrotomy -non-decalcified tooth is immersed rapidly in liquid nitrogen and sectioned with a cryostat using a heavy-duty freezing microtome. Objectives: ...

Restoration of the Severely Decayed Tooth Using Crown Lengthening with Simultaneous Tooth-Preparation

This clinical case describes a treatment approach that combines, in a single appointment, a crown lengthening procedure and the final crown preparation for the restoration of a severely decayed tooth. This approach allows for a more accurate placement of the crown margin in relation to the bone crest while reducing treatment time.

Rectifying the Tooth Preparation Errors in All-Ceramic Restorations

All-ceramic restorations have been used for long as restorative material in dentistry. However, the recent advances in both the material and technology of all-ceramic have made them a more viable treatment option. Several practitioners hesitate in giving this option to patient for fear of failure. This article describes all the failures of all-ceramic material and how to prevent them. In partic...

Tooth Preparation Using Guide Pin Instruments and the Biological Width

Previous surveys have shown that subgingival restoration margins generally lead to significant inflammation of the marginal periodontium 6, 13, 16, 17 and, inter alai, trauma of the “biological width”. This term is defined as the area of the coronal periodontium of the limbus aleovaris, which consists of the connective tissue and epithelial attachment as well as the gingival sulcus (Figure 1a)....
