What does the term 'orthograde' refer to in relation to root fillings?

The term 'orthograde' specifically refers to the process of filling a root canal from the crown of the tooth downward toward the root. This method ensures that the filling material is placed in a manner that follows the natural direction of the canal, providing optimal sealing and reducing the risk of complications such as leakage or reinfection. This technique contrasts with 'retrograde' techniques, which involve access from the root end. By filling from the crown down, dental practitioners can better control the flow of the material into the canal, ensuring a more effective treatment outcome in endodontics. Understanding this terminology is crucial in dental practice as it impacts how procedures are performed and the outcomes achieved for patients.
