Obturation is a step of the root canal procedure during which the pulp chamber is filled and sealed with gutta percha. During obturation, you’ll heat up the gutta percha, put it in the tooth, compact it, and seal it right up. Obturation creates the hermetical (fluid-tight) seal that prevents bacteria that resides in the oral cavity from entering into the periarticular tissue. OVO Dental supplies high quality obturation solutions such as ovo gutta percha points and obturation pen to support your endodontic work.
