Herbal medicaments in endodontics – Current guidelines for in vivo studies in India

Elimination of bacteria from infected root canal systems is a challenging task. Various techniques have been described to reduce the number of bacteria within the root canal system, which include chemomechanical instrumentation, use of various irrigants to remove or dissolve organic and inorganic debris, and to destroy bacteria. The intracanal medicament plays a key role in the success of root canal treatment. With the rise in bacterial resistance to antibiotics, there is considerable interest in the development of other classes of antimicrobials for the control of infection. Natural products are known to play an important role in human life. The use of herbal products as mouthwash has been tried and tested in the literature. However, the use of herbal intracanal medicament has been shown promising results when used under in vitro conditions, but in vivo studies are very scarce. This may be due to the limited supporting literature available to use it as intracanal medicament in patients due to the ethical concern. Hence, the purpose of this review is to highlight the current guidelines (laid by the drugs and cosmetics act as per the Gazette of India) regarding the use of herbal medicaments for the clinical trials in endodontics.
