Effects of food supplements on periodontal status and local and systemic inflammation after nonoperative periodontal treatment.

The present study aimed to assess the effects of a multimicronutrient food supplement on periodontal clinical parameters and systemic/local inflammatory markers. Thirty patients with severe chronic periodontitis who adhered to the Mediterranean diet (MD) underwent non-surgical therapy and daily took either the micronutrient complex (group-A) or olive oil (group-B) from baseline (T0) to 3 months (T2). Supragingival debridement was performed at T0.

Skin permeation study of dehydroepiandrosterone (DHEA) compared with its alpha-cyclodextrin complex form.

Several studies have shown that dehydroepiandrosterone (DHEA) has promising uses in a large range of pathologies including age-related illnesses (osteoporosis, atherosclerosis), immune dysfunctions, and cancer. A long-term oral dosage form would be favorable, but this type of medication has not been developed yet because of the important first-pass effect and low and variable bioavailability. A proposed alternative strategy is the preparation of DHEA for transdermal permeation, allowing direct absorption in the systemic circulation.
