Survey on CBCT usage among endodontists in the U.S.

---

Introduction

The aim of the study was to investigate the accessibility and frequency of cone-beam computed tomography usage (CBCT) and to assess the economic and logistical factors involved with its usage among active American Association of Endodontists (AAE) members, utilizing a web-based survey.

Methods

A survey of 19 questions was sent to 3,071 AAE members addressing participant access to, along with financial and logistical aspects of CBCT imaging. Descriptive analysis was performed and Fisher’s exact test utilized to test associations between groups (p<0.05)

Results

The overall response rate was 14.7% (n=544.) 95% of respondents (n=486) had an in-office CBCT unit, with those graduating after the year 2000 statistically more likely to have one (p<0.05.) Utilization of CBCT imaging for every case was reported by 40% of providers. 89% reported taking the scan at the consultation visit and 20% included this charge with the consultation fee. For those who charged for the scan separately, 85% charged more than $100. Providers who paid off their unit did so within 1-2 years (41%,) 3-4 years (36%,) 4-5 years (12%) and 5+ years (11%.) Limited field of view was utilized by 95% of respondents. 58% reported interpreting the scans themselves, 38% send only if pathology is expected and 3% always send their scans to a radiologist.

Conclusions

In conclusion, accessibility and utilization of CBCT imaging among U.S. endodontists has increased and acquisition of this equipment has not made a long-lasting financial burden on providers.
