# A retrospective cone beam computed tomography investigation of incidental findings in the maxillo-facial region

## TL;DR

This study examines how often unexpected findings appear in dental CT scans and their characteristics.

## Contribution

The study reports a high prevalence of incidental findings in CBCT scans for dental diagnostics.

## Key findings

- 90.7% of 342 CBCT scans showed incidental findings unrelated to the primary diagnostic purpose.
- A total of 631 incidental findings were recorded across the maxillo-facial region.
- Scans were analyzed using fixed parameters and a maximum FOV of 8 x 9cm.

## Abstract

The current retrospective study was intended to assess the prevalence, type and location of incidental findings on CBCT images taken
for various dental diagnostic desired outcomes. The scans were taken using the CS 8100 3D Select scanner with fixed parameters (60-90 kV,
2- 15 mA and exposure time 07-15 seconds). The maximum field of view (FOV) was 8 x 9cm, with a grey scale of 16384-14 bits. The archived
retrospective CBCT scanned images chosen for the study were classified according to gender. Out of the 342 CBCT scans evaluated, a
remarkable 300 (90.7%) indicated a total of 631 incidental results that were unrelated to the primary reason for the CBCT scan.
