There is an increasing interest in curcumin (Curcuma longa L.) as a cardiovascular disease (CVD) protective agent via decreased blood total cholesterol and low-density lipoprotein-cholesterol (LDL-cholesterol) level. The aim of this study was to investigate further the potential mechanism in the hypocholesterolemic effect of curcumin by measuring cholesterol 7a-hydroxylase (CYP7A1), a rate limiting enzyme in the biosynthesis of bile acid from cholesterol, at the mRNA level. Male Sprague-Dawley r

PURPOSE: To assess if color measurement with intraoral scanner correlates with digital colorimeter and to evaluate the possibility of application of a digital scanner for shade selection. MATERIALS AND METHODS: The L*a*b* values of the five shade tabs (A1, A2, A3, A3.5, and A4) were obtained with an intraoral scanner (TRIOS Pod) and a colorimeter (ShadeEye). Both devices were calibrated according to the manufacturer's instructions before measurements. Color measurement values were compared with

BACKGROUNDS: Despite the rapid development of digital dentistry, the use of digital intraoral scanners remains limited. The aim of this study was to evaluate the changes in views on intraoral scanners among dental hygienists after training. METHODS: Thirty-four dental hygienists with >3 years of clinical experience participated and were divided into 2 groups : iTero and Trios groups. Participants of each group practiced the usage of both intraoral scanners, for total 12 times over 4 sessions, Qu

AIM: . Four study models were prepared; bonded with ceramic, metal, and resin brackets, respectively, and without brackets. Reference images were taken by scanning the models with an industrial scanner. Study models were then applied with an artificial saliva and scanned 10 times, respectively, with the above 4 intraoral scanners. All images were converted to STL file format and analyzed with 3D analysis software. By superimposing with the reference images, mean maximum discrepancy values and me

This study aims to compare the impact of buccal and lingual brackets on the accuracy of dental arch data acquired by 4 different digital intraoral scanners. Two pairs of dental casts, one with buccal brackets and the other with lingual brackets, were used. Digital measurements of the 3D images were compared to the actual measurements of the dental models, which were considered standard values. The horizontal measurements included intercanine widths and intermolar widths. The Mann–Whitney<mml:mat

In this study, we evaluated the effects of mandibular anterior interdental space on the accuracy of intraoral scanners. Four models of mandibular arch with varying distances of anterior interdental space were analyzed; incisors were evenly spaced out between the two canines by 0 mm, 1 mm, 3 mm, and 5 mm. The full arch of each model was scanned 10 times with iTero® and Trios®. The images were superimposed with those from the reference scanner (Sensable S3) and compared using Geomagic Verify. Stat

The occlusal registration of virtual models taken by intraoral scanners sometimes shows patterns which seem much different from the patients’ occlusion. Therefore, this study aims to evaluate the accuracy of virtual occlusion by comparing virtual occlusal contact area with actual occlusal contact area using a plaster model in vitro. Plaster dental models, 24 sets of Class I models and 20 sets of Class II models, were divided into a Molar, Premolar, and Anterior group. The occlusal contact areas

위기 상황에서 다수의 공중들이 소셜미디어를 통해 정보를 공유하고, 이를 활용하여 커뮤니케이션을 하는 경향이 증가하고 있음에도 불구하고, 수용자 측면에서 소셜미디어의 영향력을 실증적으로 규명하고자 하는 연구가 거의 없었다. 따라서이 연구는 소셜미디어가 조직의 위기관리에서 어떠한 영향력을 발휘할 수 있는지를 알아보는데 그 목적이 있다. 이를 위해 미디어 유형에 따라 조직－공중 관계성과 조직이 위기 상황에서 내세우는 이미지회복전략의 차이가 공중의 위기커뮤니케이션 수용에 미치는 영향을 알아보고자 하였다. 이를 검증하기 위해 신문과 트위터를 중심으로 구체적인 위기 상황을 제시한 후 실험을 진행하였다. 삼원변량분석(3-way ANOVA) 결과, 미디어 유형과 이미지회복전략 변인은 공중의위기인식에서 상호작용 효과가 나타났다. 또한 미디어 유형, 조직－공중 관계성, 이미지회복전략 세 변인은 공중의 위기커뮤니케이션 수용에서 상호작용 효과를 나타냈다. 결과적으로 미디어 유형에 따라 공중의 위기인식과

BACKGROUND: This study aimed to develop evidence-based clinical imaging guidelines to assess the proper implant location following implant surgery and identify potential complications during follow-up. METHODS: The guideline development process employed an adaptation methodology in accordance with the Korean clinical imaging guidelines (K-CIG).
