Immediate dentin sealing of crown health and social care essay

It has been proposed that a resin coating can serve as a means to protect dental structure after preparation of the tooth for indirect restorations, sealing the exposed dentin. The resin coating is applied on the cut surfaces immediately after tooth preparation and before making an impression by assembling a dentin bonding system and a flowable composite.

Email Management of the dental tissues between the preparation and provisional phase of restorative treatment plays a pivotal role in the success of indirect adhesive restorations. In the development of these restorations, the exposed vital dentin immediately after cavity preparation is susceptible to insult from bacterial infiltration and microleakage during the provisional interim.

Bacterial and fluid penetration through these tubules can result in colonization of microorganisms, postoperative sensitivity, and the potential for subsequent irritation of the pulp. Remove excess water, leaving preparation visibly moist.

Apply adhesive primer to moist prep, then gently air dry. Surface should appear shiny; otherwise repeat process. Light cure for 10 seconds. Or, for self-etch method: After cleaning prep with disinfectant, completely dry prep and apply self-etch adhesive, agitate, air dry, then light cure for at least 10 seconds.

Block out any undercuts using flowable composite. Or for self-etch method: Redefine the preparation, including the enamel margins. The completed immediate dentin sealed preparation.

Remove the oxygen-inhibited layer of the freshly bonded surfaces with an alcohol-moistened pellet. Continue with impression-taking protocol.

Gently air dry for 10 to 15 seconds to evaporate solvent. Fabricate provisional, finish, and rinse separating medium off prep with water, then cement provisional. The "immediate dentin sealing" technique allows the development of a hybrid layer on vital teeth immediately after cavity preparation.

This hybrid layer is described as a polymerized resin intermingled with collagen fibers. It can be formed by using either a total-etch etch-and-rinse or self-etch protocol. Although these strategies differ in the method in which the dentin is treated and the adhesive system utilized, they are related in that both procedures provide an acid-resistant envelope.

This resin-infiltrated layer seals the dentin preventing microleakage. It also protects the pulp from mechanical trauma, thermal stimuli, and bacterial invasion; thus preventing hypersensitivity during impression taking, provisional restoration fabrication, and final cementation. An alternative variation, the "resin coating" technique, involves the application of a dentin bonding system followed by a low-viscosity microfilled resin on the prepared cavity.

This procedure reduces the oxygen-inhibition layer of the uncured resin by diffusion of the free radicals from the microfilled resin. In addition, for nonvital prepared teeth, this technique could protect the prepared dentin surface and intraradicular canal preparations from coronal microleakage.

However, it is important to remember that a fundamental requirement for successful adhesion is to achieve excellent isolation via the use of a dental dam during the restorative procedure.

Contamination of the enamel and dentin with saliva, moisture from intraoral humidity, blood, and crevicular fluid can compromise the bonding performance of the restorative materials by affecting the adhesion at the interface and reducing bond strengths.

It also demands a comprehensive knowledge of internal tooth structure and the complex interplay between its alteration and the adhesive mechanisms for its treatment.

With the continual development of adhesive technology, clinicians must take steps to ensure that their treatment and techniques are appropriate for the materials used. The following clinical illustration demonstrates this technique using total-etch technique, while self-etch protocol is provided Figures 1 to 8.
