The combination of different methods has been advocated to increase sensitivity in detecting secondary caries lesions. This cross-sectional study compared the detection of caries lesions around posterior restorations and treatment decisions using bitewing radiographs alone or in combination with clinical information from patient records. The radiographs (n = 212) were randomly distributed into two sequences for assessment across two phases, with a wash-out period of two weeks.

- - Repeated-sprint ability is crucial for football performance, with hamstring injuries commonly occurring during sprints when players are fatigued.
- - A study with 14 semiprofessional soccer players implemented 8 weeks of repeated-sprint training (RST), which involved multiple sets of short sprints with brief recovery periods.
- - Results showed significant improvements in sprint times and kinematic patterns, indicating that RST enhances sprint performance and promotes safer running mechanics, especially when players are fatigued.
Skin wound treatments require efficient and targeted delivery of therapeutic agents to promote fast tissue regeneration and prevent infections. Hydrogels are one of the most popular products in the wound care market, although their use as medicated wound dressings remains a massive challenge when hydrophobic drugs are needed due to the hydrophilic nature of these soft materials. In this study, we developed innovative, dynamic hydrogels based on polyvinyl alcohol (PVA), pyrogallol as a hydrogen bond crosslinker, and casein micelles as hydrophobic reservoirs of silver sulfadiazine (SSD) for enzyme-activated smart delivery at wound sites.

- A novel convolutional neural network (CNN) algorithm was developed for detecting and staging secondary caries in bitewings, as limited research exists in this area.
- The algorithm was trained using data from a Dutch dental practice, with a dataset of 2,612 restored teeth and various analytical methods to assess detection accuracy and lesion severity.
- Results showed high specificity for detecting lesions, with a correlation coefficient indicating a good agreement between the algorithm's severity scores and expert evaluations, suggesting potential for clinical use.
A novel assay was developed based on a turn-off fluorescent probe using the in situ generation of carbon dots (CDs) by means of UV/HO advanced oxidation of carbohydrates for the detection of bisphenol A (BPA) in food. Different parameters involved in the synthesis of CDs for the direct recognition of BPA have been optimised and a sensing mechanism is outlined. The presence of HO during CD synthesis causes a fluorescence enhancement due to the action of highly oxidant HO radicals formed throughout the photochemical reaction.
