10-Minute Ebd: Charcoal Toothpastes Pose Risks With Few Benefits, Kelly Lemke Dds, Ms

The Journal of the Michigan Dental Association

The rising popularity of charcoal toothpaste, fueled by social media influencers and claims of teeth-whitening benefits, prompts an investigation into its effectiveness and potential risks. The article explores the evidence through a PICO (Population, Intervention, Comparison, Outcome) question focused on patients seeking whiter teeth. A literature review reveals limited scientific validation for the cosmetic or health benefits of charcoal-containing oral products. The abrasiveness of charcoal toothpaste poses risks, potentially leading to enamel loss, dentin exposure, and hypersensitivity. Lack of fluoride in many charcoal toothpaste formulations raises concerns about caries risk. The article emphasizes the importance of dental providers conducting due …

Evaluation Of The Effect Of Two Polishing Techniques And Thermocycling Process On Surface Roughness, Hardness, And Color Stability Of Composites, Muhammet Fidan, Zeynep Dereli

Journal of Dentistry Indonesia

Simulating Implant Procedures In Dentistry, Brandon Patterson

Frameless

The School of Dentistry in partnership with the health sciences library at the University of Utah developed VR simulations for dental implants. The benefits of using the technology included providing endless scenarios, evaluation measures, and experiential learning experiences for students [1]. The school administration found that the simulations kept pace with the requirements of regulatory authorities, helped reduce costs in dental education, and found that students who trained in VR scored significantly better than traditional methods largely due to their ability to repeat tasks and receive instant feedback [2, 3].

Knowledge And Awareness Regarding Uses Of Extracted Natural Tooth In Clinical Practice, Momina Anis Motiwala, Shizrah Jamal, Karshma Devi, Rabia Ghafoor

Section of Dental-Oral Maxillofacial Surgery

Restoration of aesthetics is one the major patients’ concern in dentistry which may be disrupted due to tooth-loss secondary to trauma, or as part of orthodontic treatment or periodontal problem. A number of treatment options are available for the replacement of teeth, but they may be expensive, and time-consuming, involving artificial teeth. For immediate tooth replacement, patient’s own intentionally extracted or unintentionally avulsed tooth maybe used. The current narrative review was planned to discuss various techniques for the use of natural tooth pontic, which preserves the original contours, size and colour of the replaced tooth. Before using these teeth in …
