Different Effects of Fixed Appliances and Clear Aligners on the Microbiome and Metabolome of Dental Plaque.

Objective: This study aimed to uncover the microbial and metabolic changes in dental plaque during orthodontic treatments with fixed appliances (FAs) and clear aligners (CAs).

Materials And Methods: Twenty participants were grouped by the treatment modality they received, with 10 participants each in the FA and CA groups. Supragingival plaques were collected before orthodontic treatment (T0), after 1-3 months (T1) and more than 6 months (T2) of orthodontic treatment.

Diet and nutrient intakes and risk of non-Hodgkin's lymphoma in Connecticut women.

A population-based case-control study (601 cases and 717 controls) was conducted in 1995-2001 among Connecticut women to evaluate the relation between diet and nutrient intakes and the risk of non-Hodgkin's lymphoma (NHL). When the highest quartile of intake was compared with the lowest, the authors found an increased risk of NHL associated with animal protein (odds ratio = 1.7, 95% confidence interval: 1.
