AI Article Synopsis
- The study examined how a specific type of dental material, compomer (Dyract eXtra), affects the early development of cavities between teeth.
- One hundred sixty cylindrical and forty semispherical bovine enamel samples were tested, using both Dyract eXtra and a fluoride-free composite (Spectrum TPH), and monitored over 28 days.
- Results showed that samples in contact with the Dyract eXtra experienced significantly less caries (less fluorescence loss) compared to those with Spectrum TPH and control samples, suggesting that compomers can help reduce cavity formation.
Article Abstract
This study investigated the effect of compomer on initial interproximal caries development. One-hundred and sixty cylindrical, and 40 semispherical, bovine enamel samples (control) were prepared, polished, and sterilized. Sixty semicircular samples were prepared from each of the compomer Dyract eXtra and the fluoride-free composite Spectrum TPH. Samples were stored in water and fluoridated twice daily for 28 d. A baseline quantitative light fluorescence (QLF) image was made of each cylindrical sample. Twenty volunteers received intra-oral appliances with eight sample chambers. Each wing contained 1 control sample and either 3 Dyract eXtra or 3 Spectrum TPH samples in contact with the enamel surface of a cylindrical enamel sample. Appliances were worn for 24 h a day for 28 d except during toothbrushing (twice daily) and placement in 10% sucrose solution (five times daily). A final QLF image was made after 28 d. Caries development was analyzed as the lesion area x mean fluorescence loss (DeltaQ % mm(2)) between these and the baseline images using QLF subtract software. The median DeltaQ was significantly lower in the Dyract eXtra group (-6.1% mm(2)) than in the Spectrum TPH (-13.9% mm(2), P

Background: Maintenance of oral health, prevention, and health promotion stand as primary competencies for dental graduates. Consequently, it is necessary to promote such an approach in dental schools, which are traditionally focused on treatment, to improve the attitude and practice of students in the field of prevention, the final result of which is the reduction of oral and dental diseases in patients. The study aimed to design Integrated Oral Health Care Pathways (IOHCPs) for adults and children referred to Tehran University of Medical Sciences (TUMS), School of Dentistry.

Introduction: Early childhood caries (ECC), dental cavities in children younger than 6 years, is common, consequential, and inequitably concentrated among socially disadvantaged children. The World Health Organization and authoritative clinical and public health agencies promote 4 chronic disease management (CDM) approaches that are low-cost and can be delivered in home and community sites: pharmacologic, behavioral, monitoring, and minimally invasive dentistry (MID). The extent of adoption of these approaches among US pediatric dentists is unknown.

In this study, we evaluated the impact of Epigalocatechin-3-gallate (EGCG) on biofilm development for 24 and 46 h using high-resolution confocal laser scanning microscopy. EGCG treatment led to the formation of interspaced exopolysaccharide (EPS)-microcolony complexes unevenly distributed on the surface of hydroxyapatite disc, forming a thinner and less complex biofilm structure with significantly reduced biomass, matrix volume, and thickness compared to the NaCl treated group (negative control). At 46 h, the biofilm of the EGCG-treatment group failed to form the bacterial-EPS superstructures which is characteristic of the biofilm in the negative control group.

Article Synopsis
- Root caries pose a significant challenge in dentistry, requiring effective noninvasive preventive strategies due to poor outcomes of current restorative treatments.
- Researchers developed PAMAM-C11, a modified peptide that binds to hydroxyapatite to prevent demineralization in caries lesions and combat periodontal destruction, enhancing mineralization and resisting washout.
- PAMAM-C11 also protects against enzymatic breakdown in dentin, supports the growth of important stem cells for periodontal repair, and showed promising results in an in vivo rat model, suggesting its potential for clinical use in preventing root caries.

The aim of this narrative review is to synthesize and discuss existing evidence on the epidemiological aspects of dental pain, addressing its prevalence, risk factors, population distribution, impact on the quality of life, and implications for public health. Dental pain is a common condition that involves complex mechanisms of pain transmission and perception. Dental pain can be due to various causes, such as caries, pulpitis, periodontitis, dental trauma, and soft tissue conditions (e.
