Randomized Controlled Trial
Impact of cowpea fortified cookies on anthropometric and micronutrient status of primary school children: A randomized, single-blind controlled trial.
Micronutrient deficiencies are public health problems among school children. Food-to-food fortification may reduce the prevalence of these deficiencies. ⋯ Consumption of cowpea fortified cookies had significant positive effects on hemoglobin, serum ferritin, and vitamin A levels of school children and should be encouraged at household and industrial levels.

Randomized Controlled Trial
The effectiveness of erbium: Yttrium-aluminum-garnet laser on enamel conditioning: An In vitro study.
The purpose of this in vitro study was to investigate the effect of three different enamel surface conditioning procedures on the bonding strength of two resin-based filled fissure sealants. ⋯ As a result of the study, it has been concluded that the laser application alone has no additional benefit to the acid application in terms of bonding strength.
