[Effects of cocaine use on oral health and implications for dental treatment].

In The Netherlands, an increasing number of people use cocaine frequently, which may induce orofacial complications such as perforation of the nasal septum and palate, gingival lesions and dental erosion. In addition, recent use of cocaine increases the risk of cardiovascular complications during dental treatment, especially when local anaesthetics or adrenaline-impregnated retraction cords are used. Therefore, dental treatment should be postponed at least 6 to 24 hours after the use of cocaine.
