Background: Recently, extra-pulmonary tuberculosis (EPTB) has been increasingly reported in Bhutan, rising from 26% in 2001 to 39% in 2010. In 2016, almost half (49%) of all reported TB cases were classified as EPTB. Thus, this study was conducted to understand the epidemiology and identify risk factors contributing to increasing notification of EPTB in Bhutan.

Materials And Methods: The Adper Single Bond 2 adhesive (3 M Oral Care) was applied on moist dentin etched with PA (control) or on air-dried dentin etched with 3% aluminum nitrate + 2% oxalic acid (AN), 6.8% ferric oxalate + 10% citric acid (FO), or 10% citric acid (CA).
Purpose: To evaluate the effect of tooth brushing and dentifrice fluoride (F-) concentration on changes in color and translucency (ΔE00 and ΔT00, respectively), surface gloss (GS), surface roughness (Sa), and microstructure of a glazed CAD/CAM ceramic.
Materials And Methods: Ceramic blocks (e.max/CAD) were sectioned into rectangular plates (14 x 12 x 1 mm), and one surface of each sample was glazed.
Article Synopsis
- The study aimed to assess how the orientation of 3D-printed provisional resins affects factors like gloss, surface roughness, and color difference.
- Various 3D printers and resin types were used to create samples in different orientations, which were subjected to cleaning and testing after simulating wear from toothbrushing.
- The results indicated that the orientation of the 3D-printed resins did not have a significant impact on gloss, surface roughness, maximum profile valley depth, or color difference.
