A conservative approach to restoration assists in preserving the remaining tooth structure of extensively destroyed vital teeth. This case report describes a single-appointment chairside technique for placement of ceramic restorations in posterior teeth. A patient presented for treatment of her mandibular right first molar, which had a fractured resin-based composite restoration.

- The study investigates the role of immediate dentin sealing (IDS) in indirect restorations, aiming to determine if it should be a standard practice based on evidence from randomized clinical trials (RCT).
- A literature review identified data from four RCTs, indicating that IDS can reduce hypersensitivity one week after restoration cementation but shows no difference in longevity of the restorations.
- The conclusion suggests that while IDS can be beneficial, especially for patients at risk of sensitivity, it should be viewed as an optional step rather than a mandatory one.
Article Synopsis
- The extract from Fill Magic Flow was found to increase mutant clone spots, indicating potential genetic damage through homologous recombination.
- Other extracts didn't show significant genetic effects, aligning with their safe use in dentistry, but raise concerns about the health risks associated with some composite resins for patients and dental staff.

Article Synopsis
- A study examined the genotoxic effects of four dental resin monomers (TEGDMA, HEMA, UDMA, and BisGMA) using the Somatic Mutation and Recombination Test (SMART) in fruit flies.
- Results indicated that UDMA and TEGDMA significantly contributed to genetic mutations and homologous recombination, with UDMA being 1.6 times more genotoxic than TEGDMA.
- In contrast, BisGMA and HEMA showed no significant genotoxic effects, highlighting the need to consider findings in relation to other bioassay data for clinical implications.
Article Synopsis
- The article discusses dental ceramics, focusing on types of failures that can occur with ceramic restorations.
- It examines factors that play a role in deciding whether to repair or replace these ceramics.
- The authors promote ceramic repair as a dependable, cost-effective, and low-risk solution.
