<jats:title>Objectives</jats:title>
<jats:p>To compare the efficacy of fiber post removal using conventional (CONV) versus guided endodontics (GE) in terms of dentin loss, residual resin material, procedural errors, and working time in vitro.</jats:p>

<jats:title>Material and methods</jats:title>
<jats:p>Ninety human central incisors were root-filled and scanned by micro-computed tomography (CT), then restored with fiber posts and composite. Twenty-four sets of teeth with up to four human maxillary central incisors were fabricated and divided into three groups: conventional post removal by a general dentist (CG) or endodontology specialist (CS) and guided endodontics (GE) by a general dentist, yielding 30 teeth per operator and group. After treatment, the prepared access cavities were volumetrically assessed by micro-CT. Statistical significance was evaluated by one-way analysis of variance followed by post hoc comparisons with Tukey's HSD test and Pearson's chi-squared test for independence.</jats:p>

<jats:title>Results</jats:title>
<jats:p>Both CONV and GE resulted in dentin loss and residual resin material. CS resulted in more dentin loss and less residual resin material than CG and GE (p < .05). All groups had some deviations from the original root canal but no perforations. The shortest working time was observed in the GE group.</jats:p>
</jats:sec><jats:sec>
<jats:title>Conclusions</jats:title>
<jats:p>Compared to the conventional freehand technique, GE resulted in significantly less radicular dentin loss, a few deviations but no perforations.</jats:p>
</jats:sec><jats:sec>
<jats:title>Clinical relevance</jats:title>
<jats:p>Guided endodontics can improve the speed and safety of fiber post removal without root perforation.</jats:p>
