Activated Charcoal Dental Products: Evidence of Effectiveness Is Lacking.

October 2022
With society trending toward the avoidance of artificial components, so-called "natural" products have been gaining space and people's attention in recent years. Activated charcoal-based dental products are a prominent example of this movement because of their promise of removal of extrinsic stains or whitening of teeth by a natural means. Such products have gained popularity among patients, and companies have explored this market, launching charcoal-based and activated charcoal-based dentifrices, mouthrinses, toothbrushes, and whitening products that can be easily found at nearby stores and on the internet.

- The study examined how improper positioning of single-peak and multi-peak LEDs affects color change, microhardness, and surface topography in bulk fill and incremental dental composites after one year of aging.
- Results showed that single-peak LEDs caused significantly more color change under improper conditions, while multi-peak LEDs' performance was influenced by both the composite type and curing conditions.
- Overall, bulk fill composites exhibited better wear resistance and color stability compared to incremental composites, and multi-peak LEDs provided superior curing results in improper conditions, highlighting the importance of proper curing techniques for long-term dental outcomes.
Improper Light Curing of Bulkfill Composite Drives Surface Changes and Increases Biofilm Growth as a Pathway for Higher Risk of Recurrent Caries around Restorations.

Article Synopsis
- Dentists' curing methods for resin-based materials can negatively affect the materials' properties and their interaction with dental tissues.
- The study evaluated how different light-curing conditions (e.g., angle and distance of the light source) impact the degree of conversion, biofilm growth, and surface roughness of bulk-fill composites.
- Findings showed that non-optimal curing conditions decreased radiant exposure, leading to lower conversion rates, increased biofilm accumulation, and rougher surfaces, which could compromise the effectiveness of dental restorations.
Objectives: This study investigated the effects of physically damaged and resin-contaminated tips on radiant emittance, comparing them with new undamaged, non-contaminated tips using 3 pieces of spectrophotometric laboratory equipment.
Materials And Methods: Nine tips with damage and/or resin contaminants from actual clinical situations were compared with a new tip without damage or contamination (control group). The radiant emittance was recorded using 3 spectrophotometric methods: a laboratory-grade thermopile, a laboratory-grade integrating sphere, and a portable light collector (checkMARC).
Introduction: The durability and longevity of composite restoration are much dependent on the accurate delivery of the energy required to polymerise the material. This study aimed to investigate the extent to which undergraduate dental students acquire and retain light-curing skills following hands-on training.
Materials And Methods: Hands-on training comprises faculty tutoring for critical aspects of the light-curing procedure, such as distance and angulation of the light-curing tip.
