Purpose: The aim of this observational study is to assess the radiographic distribution and presentation of simple bone cysts (SBCs) in the jaws along with its effects on adjacent structures.

Methods: This retrospective study includes 42 cone-beam computed tomography (CBCT) scans with a radiographic diagnosis of SBC. The inclusion criteria consisted of CBCT scans acquired between 2008 and 2023 and sent to a dental school radiology department where a board-certified Oral and Maxillofacial Radiologist reviewed the images and arrived at the diagnosis of SBC. Study investigators assessed the scans using CS 3D Imaging (CareStream) and OnDemand3DApp (Cybermed) software with multiplanar reconstruction (MPR) views for measurement analysis and reviews. The lesions were analyzed at 0.5mm increments along the long axis of the defect based on size, location and effects on adjacent structures. Descriptive statistics of means, averages and calculations were employed to assess data distributions.

Conclusions:
Understanding the radiographic characteristics & distribution patterns of SBCs helps in decision-making regarding diagnosis, need for intervention, effective surgical planning, leading to better patient outcomes.
A Spearman’s rank correlation did not find a significant relationship between lesion size & scan age, although larger lesions were not noted in older scans.
Additional studies are needed to obtain a greater insight and perhaps the use of AI can help compare radiographic presentations of similar jaw cysts.
