Lycopene solid lipid microparticles with enhanced effect on gingival crevicular fluid protein carbonyl as a biomarker of oxidative stress in patients with chronic periodontitis.

Lycopene (LP), a naturally occurring carotenoid in red-coloured fruits, especially tomatoes, has a pivotal role in counteracting the deleterious effect of oxidative stress on periodontal tissues. The aim of this study is to prepare solid lipid microparticles (SLMs) encapsulating LP and to assess their biochemical and clinical effects in the management of chronic periodontitis. Optimization of SLMs was performed by assessing particle size and LP entrapment efficiency.
