Body<br />

Objectives: The aim of this study is to demonstrate the accuracy of the Cone-Beam Computed<br />

Tomography (CBCT) on detecting the dental root fractures in vitro.<br />

Methods: In the present study an in vitro model consisting 284 recently extracted human<br />

mandibular teeth without any root fractures w<strong>as</strong> used. The sample w<strong>as</strong> consisted of 210 teeth<br />

(60 molars, 60 premolars, 30 canines and 60 incisors). Among 210 teeth, 158 were fractured<br />

either horizontally, vertically or obliquely by a researcher and 52 were intact. All the teeth<br />

were placed randomly in the empty dental alveoli of a dry human mandible creating 15 different<br />

dental arcs by the same researcher. CBCT images of the models taken with Iluma CBCT<br />

Scanner (Imtec Corporation, Germany) were evaluated by three dentomaxillofacial radiologists.<br />

Results: Intraobserver agreements according to fracture types w<strong>as</strong> found statistically significant<br />

(kW=0.705, kW=0.862 and kW=0.844, respectively). Specificity and sensitivity of each<br />

observer according to first and second readings were calculated. CBCT images revealed higher<br />

sensitivities for the first and second readings between observers and it w<strong>as</strong> ranged between<br />

0.81–0.86 % and 0.82–0.89 %, respectively. Specificity for the first readings and second readings<br />

were between 88-99% and 94-99%, respectively.<br />

Conclusion: Even though, in this in vitro double-blind study, CBCT seems to give valuable<br />

data in detection of existence and type of root fractures, all of the root fractures could not<br />

be detected by three dentomaxillofacial radiologists. T<strong>here</strong>fore, dentomaxillofacial radiologists<br />

should reevaluate the CBCT images after clinical examination in the dentomaxillofacial trauma<br />

c<strong>as</strong>es.<br />
