The Relationship Between Manual Dexterity and Toothbrushing Efficiency in Preschool Children: A Crossover Study.

Aim: The aim of this study was to evaluate the relationship between oral hygiene (OH) efficiency and manual dexterity skills in Spanish five-year-old children using two fine motor tests.

Methods: A cross-sectional study with a pre-post evaluation was designed. The children's OH was measured according to the Silness and Löe plaque index (PI) before toothbrushing upon arrival at school (pre) and after supervised toothbrushing (post).

Unraveling the Anti-Aging Properties of Phycocyanin from the Cyanobacterium Spirulina ().

In recent years, marine natural products have become one of the most important resources of novel lead compounds for critical diseases associated with age. , a dietary supplement made from blue-green algae (cyanobacteria: scientific name ), is particularly rich in phycocyanin, a phycobiliprotein, which accounts for up to 20% of this cyanobacterium's dry weight and is considered responsible for its anti-cancer, anti-inflammatory and antioxidant activities. Although the anti-aging activity of phycocyanin has been investigated, how exactly this compound works against aging remains elusive.

The impact of osteogenesis imperfecta severity on oral health-related quality of life in Spain: a cross-sectional study.

Background: Osteogenesis imperfecta (OI) affects dental and craniofacial development; therefore, it can influence oral health-related quality of life (OHRQoL). The objective of this study was to explore the influence of the severity of OI on OHRQoL in adults older than eighteen years residing in Spain.

Method: Adults with OI were recruited from the Spanish Association of Crystal Bone (AHUCE) foundation.
