Abstract

Objectives

: The aim of this study was to make radiomorphometric measurements on panoramic images and evaluate the radiological findings of bones and teeth of patients with scleroderma.

Study Design

: Panoramic images of 49 patients with scleroderma and 51 healthy controls were assessed. Mandibular Radiomorphometric Indices (MRI) including mandibular cortical index (MCI), mental index (MI), panoramic mandibular index (PMI), gonial index (GI) and antegonial index (AI) were performed. Furthermore mandibular osteolysis, changes of periodontal ligament (PDL) space and changes of lamina dura were recorded for the scleroderma group.

Results

: Statistically significant differences were found for MCI (p = 0.003), MI (p = 0.001) and PMI (p < 0.001) between the scleroderma and control group, but not for GI or AI (p > 0.05). Widening of PDL space (79.6%), thickening of lamina dura (44.9%), limited mouth opening (71.4%) and osseous resorption of the mandible (8%) were detected in the scleroderma group.

Conclusions

: The radiomorphometric indices performed in the present study can be used on panoramic images to determine the existence of porous structure in mandibular cortical bone in patients with scleroderma. The most common prevalent oral radiographic manifestations of scleroderma were widening of the PDL space and of the lamina dura.
