Tooth preparation and pulp degeneration

Article Abstract:

Dentists and dental assistants need to make sure dental pulp is not injured during the placement of crowns. An old handpiece can cause trauma as can worn-out diamond burs. Tooth preparations that are too deep can injure pulp as well as improper cutting techniques and water usage. The tooth should be kept wet at all times during the procedure and the crown should be properly fitted to prevent mouth fluids and bacteria from entering the tooth. Dental assistants make most restorations, and should be properly trained in their construction. Insurance companies report that many people need root canal within 5 years of receiving a crown.

Posts and cores: state of the art

Article Abstract:

Metal posts and composite cores are used in tooth restoration and crowning of pulpless teeth. A post-and-core procedure may be required when less than half of the tooth structure remains, the tooth will support a dental prosthesis, or heavy biting force is expected. Prefabricated posts and composite resin cores are often used, and provide strong, inexpensive and predictable restoration.

Resin cements and postoperative sensitivity

Article Abstract:

Detailed instructions are presented for preventing sensitivity after placing a crown in a patient's mouth. Sensitivity seems to occur because the dentinal tubules that are opened during the etching process have not been properly sealed.
