OBJECTIVES: The objective of this study was to determine whether use of a root resorption pictogram, the Three-Dimensional Leeds Orthodontic Root Resorption Target Scale (3D-LORTS), in addition to cone beam computed tomography reports was associated with a change in orthodontic extraction decisions in cases with impacted maxillary canines and associated root resorption of adjacent teeth and to assess orthodontists' experiences using the pictogram.
STUDY DESIGN: Orthodontists completed a web-based survey in which they selected their preferred treatment plan for 6 cases. Each case was randomly presented twice, initially without and then subsequently with the pictogram. Statistical analysis was conducted to assess differences in extraction decisions with and without the pictogram and the participants' experiences using the 3D-LORTS.
RESULTS: A total of 194 orthodontists completed the survey. Significant differences in treatment decisions were found for 3 individual cases (P < .05) and for the 6 cases overall (P < .05). The majority of participants had positive perceptions of the pictogram, particularly with respect to ease of use, effect on understanding of root resorption location and severity, and usefulness as a communication aid.
CONCLUSIONS: Inclusion of the pictogram in cone beam computed tomography reports was associated with an overall change in orthodontists' extraction decisions. The majority of orthodontists reported positive experiences using the 3D-LORTS.
