Juglans regia, commonly known as the Walnut tree, is a type of a deciduous tree. The tree has many important parts, the seed, bark, husk, leaves, oil, shell of the fruit and the kernel. The plant has been used in its crude form since ages. The kernel holds nutritional value. The leaves contain an essential oil which is extracted and used. The husk contains steroids and vitamins amongst other useful compounds. The leaves are used topically as antipyretic, analgesic, antidandruff and to heal burns. The bark is tough and has been used for mechanical tooth cleaning due to its tough fibrous texture. It contains Juglone as its main and most important constituent. Juglone works as an anti-viral, anti-parasitic, anti-fungal, anti-bacterial, anti-inflammatory, and anti-cancerous agent. In dentistry it poses as an effective anti-plaque, anti-fungal, anti-bacterial, anti-cariogenic and tooth whitening material. It was concluded that in recent years, scientists and researchers have shown increasing interest towards the in depth understanding of the chemicals and compounds of the bark and its utilization in dental products towards improving dental treatment.
