Operator training and the technical quality of root canal treatment: a narrative review of the comparative evidence

Description

Root canal treatment either seals the tooth or it does not, and the radiograph afterwards shows a good deal about which. The filling has a length, a density and a taper, and the procedure leaves evidence when it went wrong: a ledge, a canal pushed out of shape, a perforation, a canal never found, an instrument snapped off inside. That makes this one of the few treatments in dentistry you can grade off a film, and it raises an uncomfortable question. How much of the quality is the operator? Undergraduates, postgraduate trainees and general dentists all do this work, in different settings and under different supervision, and most of what is published is a single clinic auditing itself, which cannot answer it. This project reads the studies that actually compare, whether by level of training, by years of experience, or by one way of teaching against another, and sets out what they show and where they contradict each other. Whatever the uncomfortable finding turns out to be, it stays in the paper rather than being smoothed out.

Student responsibilities

Read up on what makes a root canal filling good or bad on a radiograph. Take one comparison, read the papers already gathered for it, tabulate the studies, and write that section of the review.
