On account of the morphological variations of lingual dental surfaces, indirect bonding systems have been used for bonding lingual orthodontic brackets. Improvements in bracket seating and bonding systems have enabled the development of KommonBase, a precise direct bonding system. KommonBase is characterized by a large bonding base, which can achieve a good bracket fit and precise bracket positioning while also enhancing bond strength. Furthermore, transfer trays are not required because of its self-positioning shape. KommonBase offers an advantageous alternative to conventional indirect bonding systems for the bonding of lingual orthodontic brackets.

In this study, a novel phenomenon is identified where precise control of topology and generation of polyglycerol induce the retention of Na ions in biological buffer systems, effectively inhibiting ice crystal growth during cryopreservation. Unlike linear and hyperbranched counterparts, densely-packed hydroxyl and ether groups in 4th-generation dendritic polyglycerol interact with the ions, activating the formation of hydrogen bonding at the ice interface. By inhibiting both intra- and extracellular ice growth and recrystallization, this biocompatible dendritic polyglycerol proves highly effective as a cryoprotectant; hence, achieving the cell recovery rates of ≈134-147%, relative to those of 10% dimethyl sulfoxide, which is a conventional cryoprotectant for human tongue squamous carcinoma (HSC-3) cell line and human umbilical vein endothelial (HUVEC) cells.

Umami peptides have the ability to enhance food flavours and have potential health benefits. The objective of this study was to conduct a comprehensive investigation into the umami intensity, taste mechanism, and antioxidant activity of six umami peptides derived from wheat gluten hydrolysates (WGHs) and fermented WGHs. The e-tongue analysis demonstrated that the peptides exhibited a direct proportionality in terms of umami value and concentration, and were capable of enhancing the umami of commercially available condiments.

Breastfeeding is vital for infant nutrition, bonding, and overall health. However, challenges can arise with the presence of tethered oral tissues, commonly known as labial (lip) tie or lingual (tongue) tie, otherwise known as ankyloglossia. This case study explores the differential resolution of breastfeeding symptoms in a one-month-old infant with both labial and lingual ties.
