Evaluating Radiomorphometric Indices and Fractal Dimension of the Pediatric Oncology Patients on Panoramic Images

Completed

• Conditions: Bone Loss; Oncology
• Interventions: Radiation: Panoramic Radiography

• Registration Number: NCT04213482
• Lead Sponsor: Nuh Naci Yazgan University

Brief Summary

This study evaluated pediatric oncology patients in terms of quality of bone and determine any relation between bone quality and radiotherapy/chemotherapy. The alternative hypothesis is that the bone quality of the oncology patients who received radiotherapy/chemotherapy is lower than the control group.

Detailed Description

Cancer is the abnormal and uncontrolled proliferation of certain tissues in the body for a reason that cannot be determined yet. Childhood cancers occur between 0-17 years of age, and follow-up and treatment of these patients are performed in pediatric oncology services. Diagnosis in childhood cancers can be made by clinical examination as well as blood tests and examination of tissue samples. There are also some imaging methods used for diagnosis; ultrasonography, computed tomography, magnetic resonance imaging, positron emission tomography / computed tomography (PET / CT).

Treatment methods in childhood cancers are as follows; surgery, chemotherapy, radiotherapy and stem cell transplantation. Once diagnosed, oncologists and surgeons may choose one of these treatment options by mutual consultation or decide on a treatment method. Fractal analysis is a numerical as fractal dimension. Trabeculae are thin columns with numerous large spaces that give a honeycomb or spongy appearance of cancellous bone, which is also called trabecular bone or spongy bone. Previously, fractal analysis has been reported as a useful method to detect various diseases that affect the trabecular bone structure. Particularly in the field of dentistry, studies have shown that fractal analysis by the box-counting method can successfully evaluate trabecular changes in the mandible of patients with osteoporosis and periodontal diseases and in lactating women.

Arm && Interventions

Group	Intervention	Description
healthy	Panoramic Radiography	panoramic images of patients(pediatric) who have no systemic disease were collected from the archive of dental radiology clinic of the university hospital.
oncology patients	Panoramic Radiography	For this study, panoramic images were taken from pediatric patients who received radiotherapy and/or chemotherapy because of any oncologic disease.

Primary Outcome Measures

Name	Time	Method
Bone Mineral Density (BMD)	Participants to undergo a single assessment; to be measured at least 1 year after completion of oncologic therapy	Fractal Dimension of the mandibular bone in patients with pediatric oncologic diseases will be measured on dental panoramic images to asses bone mineral density of mandibula. Image J software will be used to Fractal Analysis measurements.
