dentomaxillofacial radiographic changes in a group of iranian patients with end stage renal disease undergoing hemodialysis

Introduction: this study aims to evaluate the dentomaxillofacial radiographic changes in end stage renal disease (esrd) patients who were on hemodialysis. methods: parathyroid hormone (pth), calcium, phosphorus and alkaline phosphatase (alp) measurements, as well as panoramic and periapical radiographs were obtained from seventy four patients with a history of end stage renal disease (esrd). results: 74 patients examined with age range of 15 to 68 years, and a mean age of 41.4±14.6 years. the duration of dialysis ranged between 3 to 156 months with a mean duration of 40.4 months. thinning or loss of lamina dura was observed in 16 patients (51.4%) and calcification of the pulp in 28 patients (40%). changes in trabecular pattern was observed in 30 patients (40.6%), alterations in jaw bone density in 29 patients (39.2%) and bilateral calcification of stylohyoid ligaments in 13 patients (17.6%). we did not notice any non periapical origin radiolucent lesion. there was a significant relationship between bone trabecular pattern with p level, age and duration of dialysis. changes in bone density showed significant relationship with frequency and hours of dialysis per week. conclusion: no correlation was found between the radiographic changes and ca level. although changes in trabecular pattern and density were observed mostly in those who were on hemodialysis for a relatively long time, but we could not establish a definitive relation of radiographic manifestations in esrd patients with the duration and frequency of dialysis.
