Pressure Differences from Clear Aligner Movements Assessed by Pressure Sensors.

Objectives: In this study, a clear aligner was moved at intervals of 0.25 mm and pressure variations were assessed using a sensor.

Methods: The model used for producing the clear aligner was created using a 3-dimensional printer.

Accuracy of 3-unit fixed dental prostheses fabricated on 3D-printed casts.

Statement Of Problem: Three-dimensional (3D)-printed casts are used successfully as diagnostic casts in orthodontics. However, whether 3D-printed casts are sufficiently accurate to be used as definitive casts for fixed dental prostheses (FDPs) is unclear.

Purpose: The purpose of this in vitro study was to evaluate the fit of 3-unit FDPs fabricated on 3D-printed casts made by digital light processing and to investigate the clinical applicability of 3D printing.

Evaluation of the marginal and internal fit of a single crown fabricated based on a three-dimensional printed model.

Purpose: To evaluate the fit of a crown produced based on a 3D printed model and to investigate its clinical applicability.

Materials And Methods: A master die was fabricated with epoxy. Stone dies were fabricated from conventional impressions (Conventional stone die group: CS, n=10).

A comparison of different thicknesses of mouthguards according to the groove shape of sheets.

Background/aims: Previous studies have compared the thickness of the device with and without grooves. The result was a difference in thickness of the device along the groove. The aim of this study was to assess the differences in thickness of mouthguards that result from different groove shapes of ethylene vinyl acetate sheets used to make these appliances.

Comparing the accuracy (trueness and precision) of models of fixed dental prostheses fabricated by digital and conventional workflows.

Purpose: This study aimed to evaluate and compare the accuracy.

Methods: A reference model was prepared with three prepared teeth for three types of restorations: single crown, 3-unit bridge, and inlay. Stone models were fabricated from conventional impressions.

Evaluation of shear bond strength of veneering ceramics and zirconia fabricated by the digital veneering method.

Purpose: The purpose of this study was to evaluate the shear bond strength (SBS) of veneering ceramic and zirconia fabricated by the digital veneering method.

Methods: A total of 50 specimens were fabricated, i.e.

Transcriptional and translational expression of calbindin-D9k in the duodenum, kidney and uterus of a female canine model.

Calbindin-D9k (CaBP-9k) is a cytosolic calcium-binding protein expressed in tissues in the intestine, uterus, placenta, kidney, pituitary gland and bone. Its exact function is unknown, but it is considered to regulate intracytoplasmic concentration and transport of free ions (Ca(2+)). CaBP-9k protein is involved in intestinal calcium absorption in the intestine and in the regulation of myometrial activity by intracellular calcium in the uterus.

Panax ginseng enhances cognitive performance in Alzheimer disease.

Recent experimental evidences suggest protective and trophic effects of ginseng in the memory function of Alzheimer disease (AD). Thus, we investigated the clinical efficacy of Panax ginseng in the cognitive performance of AD patients in an open-label study. Consecutive AD patients were randomly assigned to the ginseng (n=58) or the control group (n=39), and the ginseng group was treated with Panax ginseng powder (4.
