A fistula in dental practice is significant primarily as an effective drainage pathway from an abscess. When an abscess forms in the dental pulp area, it leads to the accumulation of pus, creating pressure that needs to be relieved. A fistula allows this pus to drain to the surface of the gums or oral cavity, thus providing a channel for the infection to escape. This drainage can help alleviate pain and prevent the spread of the infection.

In contrast, a healthy pulp would not typically be associated with a fistula, as fistulas are indicative of ongoing pathological processes. They do not point to the presence of cavities either, since cavities generally manifest differently and are unrelated to such a drainage mechanism. Furthermore, although cleaning the root canal is an essential aspect of endodontics, a fistula itself is not a tool or method employed in that procedure; rather, it is a sign of underlying issues that necessitate treatment, which may include root canal therapy. Hence, the presence of a fistula is a crucial indicator of infection and the need for clinical intervention.
