Aim and objective: Assess the effect of anti tar toothpaste (X TAR) and its impact on calculus prevention. X tar toothpaste provides better action in calculus prevention when compared to mechanical removal alone. Background: Dental calculus is composed of inorganic components and an organic matrix. Different calcium phosphates which include hydroxyapatite make up the mineral components of dental calculus. Mineralization of dental plaque can be delayed by the presence of crystallization inhibitors, such as pyrophosphate .The X TAR toothpaste consists of pyrophosphates which prevents the calculus formation. Our current study includes usage of anti tartar toothpaste in gingivitis patients after scaling and evaluated after 1 month Result: This study showed that the use of x TAR toothpaste has its own action in calculus prevention with the help of pyrophosphates present in it.
