Changes in jawbones of male patients with chronic renal failure on digital panoramic radiographs

Abstract

Objective:To compare the existence of gonial cortical bone thickness, antegonial index, mandibular canal bone resorption and gonial angle values and pathologies like ground-glass appearance in jawbones and brown tumor in male patients undergoing dialysis due to chronic renal failure and men from the healthy control group on panoramic radiographs.Materials and Methods:Panoramic radiographs were taken from 80 male individuals in total (40 normal and 40 dialysis patients). Values obtained from the right and left sides of the mandible were summed and their means were calculated. Gonial cortical thickness, antegonial index and gonial angle values were assessed with the Student's t-test, mandibular canal wall resorption with the Chi-square test, and pathologies such as ground-glass appearance and Brown tumor as “available” or “not available.”Results:Statistically significant differences were observed among the antegonial index (P < 0.001), gonial cortical bone thickness (P < 0.001), and gonial angle (P < 0.001) values of study and control groups. Besides, mandibular canal wall resorption (P < 0.001) was also statistically significant. In the study group, pathologies with ground-glass appearance were encountered in mandible, but no radiographic findings were observed similar to brown tumor.Conclusions:Compared to the control group, decreases were found in gonial cortical bone thicknesses, antegonial index values, mandibular canal wall resorption, and gonial angle values of the patients receiving dialysis treatment due to chronic renal failure. Although it is not statistically significant, pathology with ground-glass appearance was detected in a patient, but no pathologies like brown tumor were observed. These findings from patients with chronic renal failure must be evaluated in panoramic radiography.

Evaluation of mandibular inferior cortex changes in patients candidate for liver and kidney transplantation using panoramic view

“…Dagistan et al found a significant decrease in antegonial index, gonial cortical bone thickness, and gonial angle values in chronic renal failure patients. Additionally, mandibular canal wall resorption was also statically significant (18). Similarly, in this study we found a significant difference between cases and controls in mandibular cortical thickness.…”

“…Incidence of CKD is 377 per million in the United States. CKD increases with age and males are more commonly affected than females (18). The dialysis patient's number in Iran is almost 13 000 and the renal transplant patient's number is almost 17 000.…”

“…The frequency of bone disease in cirrhotic patients was reported to be 12% to 55% by Patel et al (17). In the study by Dagistan et al, pathologic defects with ground-glass appearance were seen in the mandible (18). Although many aspects of CKD and CLF have been searched, there are few studies about the effect of these diseases on jaw bones in literature.…”

Correlation of Radiomorphometric Indices of the Mandible and Biochemical Parameters in Patients with Secondary Hyperparathyroidism Due to Chronic Kidney Disease

“…However, there is no consensus among researchers regarding the use of panoramic radiograph as a reliable tool for the diagnosis of osteoporosis. 4 8 10 19 In this respect, studies indicate the MI and MCI to be the best parameters for the identification of osteoporosis on panoramic radiographs and reference values for mandibular cortical thickness of 3.0, 3.15, and 3.5 mm have been suggested for the study of osteoporosis. 2 4…”

Penilaian kualitas kortikal mandibula pasien diabetes mellitus tipe 2 dengan analisis radiomorfometrik pada radiograf panoramik

“…Penilaian dilakukan secara visual dengan mengklasifikasikan bentuk morfologi korteks inferior mandibula sepanjang foramen mentalis hingga regio antegonial ke dalam tiga kategori: C1, margin endosteal dari korteks terlihat tajam dan tegas pada kedua sisi, menandakan bahwa korteks dalam kondisi normal dan tidak terjadi perubahan; C2, margin endosteal memiliki defek semilunar atau membentuk residu (satu hingga tiga lapisan) pada satu atau kedua sisi (mild to moderately eroded cortex); C3, lapisan kortikal membentuk endosteal dengan residu yang lebih tebal dan berporus dengan ketebalan yang berkurang (severely eroded cortex). 8,9,10 Pengukuran ketebalan kortikal mandibula menggunakan Antegonial Index dilakukan pada area yang terletak pada anterior sudut gonial, yakni berupa garis yang tegak lurus terhadap korteks pada garis yang menghubungkan batas anterior dari ramus ascendens hingga batas bawah mandibula. Pengukuran dilakukan pada sisi kanan dan kiri mandibular, yang kemudian diambil nilai rata-rata sebagai hasil akhir menggunakan software Image-J (National Institute of Health, Bethesda, MD, USA).…”
