Article Synopsis
- The study aimed to evaluate how different interdental spaces and the presence of the palate affect the accuracy of maxillary scans taken with three different intraoral scanners.
- The research involved creating a virtual maxillary cast with varying interdental spaces (0, 1, 2, and 3 mm), which were then scanned using TRIOS4, iTero Element 5D, and Aoralscan2 to measure scanning accuracy through root mean square error calculations.
- Results indicated that interdental spaces of 1 and 2 mm yielded the best accuracy, while scans including the palate were significantly more accurate than those without, highlighting the important role of these factors in achieving precise maxillary scans.
Purpose: The variation in findings with regards to the accuracy and precision of intraoral scanners for shade selection are no doubt confusing for clinicians who may find it difficult to make evidence-based decisions. The aim of this systematic review is to provide a comprehensive and in-depth assessment of available studies to determine the viability of using intraoral scanners for the purpose of shade matching. The PICO-guided research question is as follows: when shade matching, are intraoral scanners as valid as visual or other digital shade measuring devices in determining tooth colors.

The objective of this study is to evaluate the accuracy of using two clinical color measuring instruments, VitaEasyshade and Spectroshade, against a referent laboratory color measuring instrument (Spectroradiometer PR670).
Methods And Materials: The validity and repeatability of the referent laboratory color measuring instrument was assessed using standard color patches with certified CIE L*a*b* values.
Purpose: The aim of this systematic review was to evaluate and compare three commonly used proportions that include the golden proportion, golden percentage, and Recurring Esthetic Dental (RED) proportion to identify which of the mathematical formulas, if any, can be used to provide predictable and repeatable esthetic clinical outcomes.
Methods: A comprehensive search of electronic databases that included EBSCO, ProQuest, SCOPUS, Science Direct, Wiley, Google Scholar and PubMed was conducted using the terms: "golden proportion," "golden percentage," and "Recurring Esthetic Dental (RED) proportions" alone or in concurrence with one or both ensuing terms: "tooth proportions" and "esthetic tooth proportions." In addition, the following journals were hand searched for relevant articles: Journal of Prosthodontics, Journal of Prosthetic Dentistry and Journal of Esthetic and Restorative Dentistry.
Cognitive decline is one of the major causes of disability among the aging population. The aim of this study was to explore the relationship between oral health parameters (number of teeth, chewing ability, and presence of a denture) and cognitive function in the elderly across the UAE. Fifty persons (age ≥ 60; 71.

Methods: Two hundred and seventy-six subjects with urodynamic stress or mixed urinary incontinence underwent retropubic midurethral slings (TVT, N = 99; SPARC, N = 52) or transobturator slings (Monarc, N = 125). All evaluable subjects had a routine office evaluation, subjective assessment of UUI, and multichannel urodynamic testing pre- and 3 months postoperatively.
