AI Article Synopsis
- The study investigates the relationship between tongue pressure and masticatory performance in children with Class I and Class II malocclusions.
- Findings indicated that children with Class II malocclusion exhibited lower maximum tongue pressure, hand grip strength, and occlusal force compared to those with Class I.
- Significant correlations were found in Class I malocclusion between tongue pressure and various factors, whereas in Class II malocclusion, the correlations were primarily linked to physical attributes like height and weight.
Article Abstract
Background: The relationship between tongue pressure and masticatory performance during the mixed dentition period in cases of Class II malocclusion has not been clarified. The aim of this study was to determine differences in tongue pressure-related factors, including maxillofacial morphology and masticatory performance, between Class I and Class II malocclusions during the mixed dentition period.
Methods: A total of 56 children with Class I malocclusion (12 boys, 16 girls) or Class II malocclusion (16 boys, 12 girls) with mixed dentition were included in the present study. Height, body weight, hand grip strength, maximum occlusal force, maximum tongue pressure, masticatory performance, and the number of decayed, missing, and filled teeth were measured in all participants. Their lateral cephalograms were also evaluated. The means of all measurements were compared between Class I and Class II malocclusions. Pearson's correlation coefficients were used to determine associations between maximum tongue pressure and other variables for each type of malocclusion.
Results: The maximum tongue pressure, hand grip strength, and maximum occlusal force in the Class II malocclusion group were significantly lower than those in the Class I malocclusion group (all, p < 0.05). The maximum tongue pressure was significantly positively correlated with hand grip strength, maximum occlusal force, masticatory performance, and SNB (sella, nasion, B point) angle in the Class I group (all, p < 0.05), and with height, body weight, and labial inclination of the central incisors in the Class II group (all, p < 0.05).
Conclusions: The maxillofacial morphometric factors associated with tongue pressure were clearly different between cases of Class I and Class II malocclusion with mixed dentition. Masticatory performance and tongue pressure were significantly positively correlated in cases of Class I malocclusion, but not in cases of Class II malocclusion.

A random forest algorithm combined with correlation analysis, was employed to identify key taste compounds in Huangjin green tea by using an electronic tongue. A total of 45 commercial Huangjin green teas were analysed for their amino acids, catechins, gallic acid, and caffeine using an amino acid analyser and HPLC. In this study, taste compounds of 30 were quantified, and 16 of these compounds exhibited taste activity values greater than 1 in the tea samples, including 6 amino acids, 8 catechins, as well as gallic acid and caffeine.

The oxygen reserve index (ORi) is a novel, non-invasive parameter that estimates arterial oxygen partial pressure (PaO) during hyperoxia when the fraction of inspired oxygen (FiO) is elevated. This study aimed to assess the utility of the ORi/FiO ratio as an index for quantifying F-shunt, serving as an estimate of venous admixture. Anesthetic records were reviewed from 44 dogs undergoing general anesthesia and requiring arterial catheterization.
