Diagnosis of Decreased Bone Density by Dental Cone Beam Computed Tomography
Diagnosis of Decreased Bone Density by Dental Cone Beam Computed Tomography
The purpose of this study is to elucidate the role of Dental Cone Beam Computed Tomography
 (CBCT) in assessment of bone density. The study population contains men and women above the
 age of 60 years, eligible for Bone Density Testing in accordance with their health insurance,
 who underwent a Dental CBCT recommended by their Dental Practitioner. Any patient (eligible
 for bone density screening by age criteria) undergoing CBCT of either one of the jaws (or
 both) due to dental reasons, will be sent to a bone mineral density DEXA Scan, and for blood
 testing for PTH, Phosphor, Calcium ,Vitamin D and Creatinine levels.

 Density measurements will be done in specific sites on the CBCT's of the jaws. These
 measurements will be correlated with the blood tests and DEXA scan results.
The purpose of this study is to elucidate the role of Dental Cone Beam Computed Tomography in
 assessment of bone density.

 The study population contains men and women above the age of 60 years, eligible for Bone
 Density Testing in accordance with their health insurance, who underwent a Dental CBCT
 recommended by their Dental Practitioner. Any patient (eligible for bone density screening by
 age criteria) undergoing CBCT of either one of the jaws (or both) due to dental reasons, will
 be sent to dual energy x-ray absorptiometry (DEXA) Scan, and for blood testing for
 parathormone (PTH), Phosphor, Calcium ,Vitamin D and Creatinine levels.

 The investigators estimate thousands of Dental Cone Beam Computed Tomographies are being
 ordered every year, due to dental needs in Israel. In this preliminary prospective pilot
 study the investigators will evaluate 50 subjects who underwent both Dental CBCT and DEXA
 scan as a preliminary testing.

 Density measurements will be done in specific sites on the CBCT's of the jaws. These
 measurements will be correlated with the blood tests and DEXA scan results.

 The outcomes of this study are:

 1. Bone density measurement on Dental CBCT can be used for diagnosis of low bone mass
 conditions.

 2. There is an association between bone density DEXA results, blood tests for Calcium,
 Phosphor, PTH and Vitamin D and Bone density measurements on Dental CBCTs.
Inclusion Criteria:

 1. Men and women above the age of 60 years.

 2. Underwent Dental Cone Beam Tomography for dental reasons, up to three months before
 screening.

 3. Patients underwent bone density examination at Soroka Medical Center only, during the
 last year prior commencing the research will be eligible for participation without the
 need for an additional bone density scanning.

 Exclusion Criteria:

 1. Patients with current or past treatment of any osteoporotic medication: Alendronate
 (Alendronate teva, Fosamax, Maxibone , Fosalan, Fosavance), Residronate (Actonel.
 Ribone), Zoledronic acid (Aclasta, Zomera), Denosumab (Prolia), Teriperatide
 (Forteo),Raloxifen ( Evista), Stronsium Ranelate (Protelos).

 2. Patients taking Corticosteroid Therapy.

 3. Patients with history of Head and Neck Neoplasia or Head and Neck Irradiation or Bone
 Metastasis.

 4. Patients with hard tissue pathology of the jaws.

 5. Patients after laminectomy and or fixation of lumbar vertebrae or after bilateral hip
 replacement.

 6. Diagnosis of primary hyperparathyroidism.
