Uncut Enamel For Optimizing Bonded Composite Restoration On Multiple Diastema Closure Cases, Citra Kusumasari, Meiken Hayashi, Yasushi Shimada

Journal of Dentistry Indonesia

The main advantage of using a minimal invasive strategy concept by uncut enamel technique while doing direct composite restoration is to create a color and translucency close to the natural teeth with long-term bonding durability. Objective: This case report presents an uncut enamel technique for multiple diastema closure cases using direct composite restoration. Case Reports: an 18-year-old male and a 50-year-old female patient complained of diastema in their upper front teeth and requested aesthetic correction. Digital mock-up was made prior to the uncut enamel technique for showing the expected results to the patient and as a guidance for the …

Makara Journal of Health Research

Background: The aim of this study was to compare three different pulp coverage materials with calcium silicate content considering microleakage in the cavity floor and evaluate the gaps with a stereomicroscope and scanning electron microscope SEM.

Methods: A total of 40 human molar teeth were used in this study, and class V (4 mm mesio-distal × 3 mm gingivo-occlusal × 3 mm depth) cavities were prepared. The samples were divided into four groups (N = 10), including NeoPutty(Nusmile), Biodentin (Septodont), and TheraCal PT (Bisco). All groups were restored using Single Bond Universal adhesive and Filtek Z250 (3M ESPE). …

Polymer Chemistry Of Dental Adhesives, Alia J. Rubaie, Karen A. Schulze

Pacific Journal of Health

Dental adhesives are water soluble, non-toxic materials that bind composite resins to dentin and enamel. Adhesive systems are dependent on a polymerization process at the interface and require different moieties to prepare the substrate to effectively interact with the tooth surface. Due to their critical role in restorative procedures, many chemists are interested in strengthening the adhesive bond strength at the interface. This review paper covers the evolution of dental adhesive systems over time and provides an extensive overview of what components make up a dental adhesive system. Additionally, this article explores the common issues found in adhesive systems, and …

Different Irrigant Activation Techniques In Removing Dentin Debris: An In-Vitro Study, Maya T. Eter, Roula S. Abiad

BAU Journal - Creative Sustainable Development

During endodontic treatment, the efficiency of irrigation depends on two criteria: the antimicrobial and dissolving properties of the irrigation solution and the delivery system used that dictates the flushing action of the irrigant and consequently enable it to reach complex areas. The purpose of this in-vitro study was to compare the cleaning efficiency of EDDY sonic activation with needle irrigation and passive ultrasonic activation regarding elimination of dentin debris. Forty single rooted extracted teeth were instrumented and then were split in bucco-lingual direction. A longitudinal groove was performed in the inner surface of one root half of each tooth. Grooves …

Too Much Of A Good Thing: Case Of Fluoride Toxicity, Swet Patel, John Polunin, James Espinosa, Alan Lucerna, Trent Malcolm

Rowan-Virtua Research Day

Overall, the beneficial role of fluoride for the maintenance of proper dental hygiene has been known for many decades which has been corroborated by a plethora of research. Media and culture have further highlighted how using fluoride supplementation can help with dental cavities. It is clear that just as there are benefits to fluoride usage, there also risks. Further awareness needs to be made that showcases the downfalls of excess fluoride use. Labels need to be placed on fluoride products that emphasizes the dosing. It is imperative that people are educated on the toxicity of fluoride as too much of …

Quantification Of Dental Fissures Through Occlusal Topography Analysis, Duru Erkan

Biological Sciences Undergraduate Honors Theses

Narrow, deep, and elaborate dental fissures are widely believed to increase the predisposition of enamel to develop carious lesions as these surfaces are thought to be ideal for cariogenic bacteria to adhere to. Therefore, dentists prescribe sealants as a preventative measure for patients with such fissures to avoid tooth decay. Yet to date, there is no objective data supporting the notion that fissure morphology actually affects caries susceptibility, nor is there a quantifiable, clinically practical method to characterize fissure patterns expected to increase risk of caries disease.

In this study, three new methods to quantitatively characterize fissure pattern in mandibular …

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 …

Journal of Dentistry Indonesia

Drug-influenced gingival enlargement (DIGE) among hypertensive patients is commonly associated with antihypertensive drugs such as calcium channel blockers (CCBs). Immune response alteration is one of the proposed mechanisms for DIGE. Immunoglobulin A (IgA) in saliva which involves in defense mechanism was shown to be affected in patients with DIGE. Objective: This study aimed to determine the association of salivary IgA level with DIGE. Methods: This cross-sectional study comprised 47 hypertensive patients who had consumed antihypertensive drugs for at least 3 months. Twenty-one (44.7%) males and 26 (55.3%) females had participated in this study. Data was analyzed using SPSS version 26.0. …

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].
