Immediate Dentin Sealing: A Literature Review

Area of Science:

• Dentistry
• Dental Materials Science
• Restorative Dentistry

Background:

• Immediate dentin sealing (IDS) is a technique involving the application of a dentin-bonding agent after tooth preparation and before impression-taking.
• This technique has been proposed to offer advantages in reducing bacterial microleakage, managing dentin hypersensitivity, and improving overall bonding quality in indirect restorations.

Purpose of the Study:

• To review existing literature and clarify aspects related to the application of immediate dentin sealing (IDS).
• To evaluate the benefits and potential drawbacks of IDS concerning bacterial microleakage, hypersensitivity, and bonding quality.

Main Methods:

• A comprehensive electronic literature search was conducted across major databases (MEDLINE, Cochrane, Ovid, Scopus).
• Studies published between January 1990 and December 2020, encompassing both in vitro and clinical research on the IDS technique, were included.

Main Results:

• Assessment of 88 relevant articles indicated that IDS is advantageous for bond strength, gap formation, bacterial microleakage, and dentin hypersensitivity.
• However, specific challenges related to impression material interaction, the provisional restoration phase, and pre-cementation conditioning require additional investigation.

Conclusions:

• The literature review found no documented contraindications for clinicians to adopt IDS in their daily practice.
• The IDS technique appears to offer significant benefits for indirect dental restorations, supporting its clinical application.
