Abstract

Objective:The aim of the present study was to assess the efficiency of dental volumetric tomography (DVT) radiomorphometric indices to detect osteoporosis in post-menopausal females, compare them with the osteopenic and normal groups and to assess the correlations of the DVT findings with the bone mineral density values measured by dual X-ray absorptiometry (DEXA).
Methods:This study consisted of 120 post-menopausal females, with age ranging from 48 to 67 years. Based on their DEXA results, they were classified into osteoporotic, osteopenic and normal groups. Dental volumetric tomographical radiomorphometric indices were measured and compared with dual energy x-ray absorptiometry parameters of the patients.
Results:Dental volumetric cortical thickness (DVT-CT) displayed significant differences between the groups and decreased in osteoporotic individuals. The mean values of dental volumetric tomographic mandibular index superior (DVT-MIS) and dental volumetric tomographic mandibular index inferior (DVT-MII) for osteoporosis group was significantly lower than osteopenic and normal groups. In both normal and osteopenic patient groups, there were significant correlations between the spine t score and DVT-MIS (p<0.05). Osteoporotic patient group displayed statistically significant relationship between spine t score and DVT-CT.
Conclusion:DVT-CT parameter which was found to be associated with the spine DEXA measurements, can be used to diagnose osteoporotic patients. Dental volumetric tomography can help clinicians as a useful tool to evaluate osteoporotic patients.

Osteoporoz Teşhisinde Dental Volümetrik Tomografiden Üretilen Radyomorfometrik İndekslerin Etkinliği

Abstract

Giriş/Amaç:Bu çalışmanın amacı post-menapozal hastalarda osteoporozu saptamak için dental volumetrik tomografi (DVT) radyomorfometrik indekslerinin etkinliğini saptamak, bunları osteopenik ve normal gruplarla karşılaştırmak ve çift enerjili X-ışını absorpsiyometrisi (DEXA) ile ölçülen kemik mineral yoğunluğu değerleri ile DVT bulgularının korelasyonlarını değerlendirmektir.
Gereç ve Yöntemler:Bu çalışmaya, yaşları 48- 67 arasında değişen 120 post-menopozal hasta dahil edildi. Çalışma grubu DEXA sonuçlarına göre osteoporotik, osteopenik ve normal olarak sınıflandırıldı. Dental volumetrik tomografik radyomorfometrik indeksler ölçüldü ve hastaların çift enerjili X-ışını absorpsiyometri parametreleri ile karşılaştırıldı.
Bulgular:Dental volumetrik kortikal kalınlık (DVT-KK) gruplar arasında önemli farklılıklar gösterdi ve osteoporotik bireylerde azaldı. Osteoporoz grubunda dental volümetrik tomografik mandibular indeks superior (DVT-MIS) ve dental volümetrik tomografik mandibular indeks inferior (DVT-MII) ortalama değerleri, osteopenik ve normal gruplara göre anlamlı olarak düşüktü. Hem normal hem de osteopenik grupta, omurga t skoru ile DVT-MIS arasında anlamlı korelasyon vardı (p <0.05). Osteoporotik hasta grubu, omurga t skoru ile DVT-KK arasında istatistiksel olarak anlamlı ilişki gösterdi.
Sonuç:Omurga DEXA ölçümleri ile ilişkili olduğu bulunan DVT-KK parametresi, osteoporotik hastaları teşhis etmek için kullanılabilir. Dental volümetrik tomografi, klinisyenlere osteoporotik hastaları değerlendirmek için yararlı bir araç olarak yardımcı olabilir.
