Assessment of dental caries lesion activity status using quantitative parameters obtained from the quantitative light-induced fluorescence method and difference of microbial distribution in primary molars.

Background: This study aimed to assess differences in quantitative measures obtained from the quantitative light-induced fluorescence method and microbial composition of carious dentin and saliva according to the activity status of caries lesions in primary molars.

Methods: A total of 34 teeth from 34 children were evaluated in this study. The activity status of carious lesions was classified using the International Caries Classification and Management System criteria (active or inactive).

Treponema denticola as a prognostic biomarker for periodontitis in dogs.

Periodontal disease is one of the most common disorders in the oral cavity of dogs and humans. Periodontitis, the irreversible periodontal disease, arises progressively from gingivitis, the reversible inflammatory condition caused by dental plaque. Although the etiology of periodontitis has been widely studied in humans, it is still insufficient for the etiological studies on periodontitis in dogs.

Arabidopsis annexins AnnAt1 and AnnAt4 interact with each other and regulate drought and salt stress responses.

Annexins are Ca2+--and phospholipid-binding proteins that form an evolutionarily conserved multigene family throughout the animal and plant kingdoms. Two annexins, AnnAt1 and AnnAt4, have been identified as components in osmotic stress and abscisic acid signaling in Arabidopsis. Here, we report that AnnAt1 and AnnAt4 regulate plant stress responses in a light-dependent manner.
