Analysis of mandibular changes using panoramic-based indices in patients with chronic renal failure

Abstract

Introduction

Chronic renal failure (CRF) is a progressive disease affecting many systems and causing dental and periodontal problems, in particular a decrease or loss in the amount of cortical bone that is visible on radiographs. Panoramic radiography is useful for determining these changes. The aim of this study was to evaluate cortical parts of the mandible using panoramic-based indices in patients with CRF.

Methods

70 subjects with CRF were included in the study. The measurements of panoramic indices were made according to the visibility (mandibular cortical index, MCI) and thickness (mental index, MI) of the inferior cortex of the mandible. Then, these indices, obtained from 70 healthy controls of the same age and gender, were assessed and the results were compared. The effects of dental status and hemodialysis duration on MCI and MI were also investigated.

Results

The frequency of an eroded cortex was significantly elevated in patients with CRF (p<0.05). The mean MI was lower in patients with CRF than in healthy subjects (5.53 ± 1.62 and 5.73 ± 1.31 mm, respectively), but the difference was not statistically significant (p>0.05). No correlation was found between hemodialysis duration and mandibular indices (p>0.05). Dental status was not associated with mandibular indices (p>0.05).

Conclusions

These results suggest that MCI might be a useful radiographic parameter for evaluating changes occurring in the cortical parts of the mandible in CRF patients. Clinicians should be aware of these changes while planning invasive dental treatments in CRF patients.
