Caries Lesion Assessment Using 3D Virtual Models by Examiners with Different Degrees of Clinical Experience.

: Dental caries is a preventable, reversible disease in its early stages. This study evaluated the intra-rater agreement of International Caries Assessment and Detection System (ICDAS) scores with Medit i500 and Omnicam scanners versus traditional clinical examinations and the inter-rater agreement using the Omnicam among senior dentists and dental students and between these two groups. : A total of 24 patients aged between 21 and 34 years, randomly selected from dental students and interns, underwent four examinations (three intraoral scans and one clinical examination), and the corresponding ICDAS scores were recorded by a randomly selected rater out of the 31 available examiners.

Recent Trends in Hydroxyapatite Supplementation for Osteoregenerative Purposes.

Bone regeneration has gained attention in the biomedical field, which has led to the development of materials and synthesis methods meant to improve osseointegration and cellular bone activity. The properties of hydroxyapatite, a type of calcium phosphate, have been researched to determine its advantages for bone tissue engineering, particularly its biocompatibility and ability to interact with bone cells. Recently, the advantages of utilizing nanomolecules of hydroxyapatite, combined with various substances, in order to enhance and combine their characteristics, have been reported in the literature.

Evaluation of smartphone dental photography in aesthetic analysis.

Aims To investigate the influence of the system used for digital photography upon the aesthetic analysis in dental medicine.Materials and methods The aesthetic parameters were evaluated on photographs taken with different systems: two DSLR camera set-ups (DSLR + ring flash and DSLR + twin flash) and a smartphone-based system using a five-point Likert scale questionnaire.Results Generally, the DSLR camera + twin flash photographic method performed the best with an overall average score of 4.

Solid Plasmonic Substrates for Breast Cancer Detection by Means of SERS Analysis of Blood Plasma.

Surface enhanced Raman spectroscopy (SERS) represents a promising technique in providing specific molecular information that could have a major impact in biomedical applications, such as early cancer detection. SERS requires the presence of a suitable plasmonic substrate that can generate enhanced and reproducible diagnostic relevant spectra. In this paper, we propose a new approach for the synthesis of such a substrate, by using concentrated silver nanoparticles purified using the Tangential Flow Filtration method.
