Comparative evaluation of intraoral scanners and a spectrophotometer for percent correct shade identification in clinical dentistry.

Objectives: The study aimed to assess the percent correct shade identification of four intraoral scanners (IOS) and a spectrophotometer, focusing on how reliably each device selects the correct tooth shade compared to a visual observer's selection. The research question addresses how much clinicians can trust the device-selected shade without visual verification.

Materials And Methods: Sixteen participants with natural, unrestored teeth were included.

Exploring the Relationship Between Public Social Media Accounts, Adolescent Mental Health, and Parental Guidance in England: Large Cross-Sectional School Survey Study.

Background: Although associations between social media use and adolescent mental health have been described, more information is needed on the potential components characterizing this complex exposure, in particular, those related to maintaining a public social media account.

Objective: This study aims to investigate the association between having a public social media account and anxiety and depression in school-going adolescents.

Methods: Overall, 80 secondary schools and further education colleges in England were sampled using a cross-sectional web-based survey as part of the 2023 OxWell Student Survey.

High-resolution dendrometer measurements reveal different responses of Douglas-fir to extreme drought in 2018 depending on soil and rooting characteristics.

Introduction: Douglas-fir ( (Mirb.) Franco) is considered an important non-native substitute tree species in Europe, especially for Norway spruce ( (L.) Karst.

Caregiver Psychopathology, Resilience, and Their Associations with Social-Emotional Challenges of Young Children Affected by Armed Conflict in Colombia.

We examined the social and emotional challenges (SEC) of young children and the mental health of their caregivers in areas affected by armed conflict and displacement in Colombia. Anxiety, depression, and PTSD symptoms were assessed in 1,133 caregivers. Caregivers also reported on the SEC of their children aged 21-53 months.

A novel approach for the replacement of accuracy and precision measurements with the visual instrument agreement scale (VIAS) in evaluating the performance of four intraoral scanners and one shade measurement device.

Objectives: The terms 'accuracy' and 'precision' are tightly defined in color science but are often used ambiguously in dental research. This study introduces the visual instrument agreement scale (VIAS), a new method for determining visual-instrumental agreement in dental colorimetry by comparing visually perceived and measured color differences.

Materials And Methods: In-vivo tooth color measurements were taken from 16 participants using four intraoral scanners (Primescan, Medit i700, Carestream CS3700, Trios 3) and one spectrophotometer (Vita Easyshade V).
