Bottom Line: Maximum number of ties for LD in anteriors was seen in coronal section (16) and in posteriors with sagittal section (17).Assessing PDL space in anteriors, high number of ties was seen with coronal section (25) and sagittal section (21), while for posteriors showed a high number of ties in all sections.LD could be observed and reported in coronal section for anteriors and in sagittal section for posteriors and PDL space in all the sections for both anteriors and posteriors.

ABSTRACT

Objectives: To retrospectively evaluate the subjective quality of images of cone beam computed tomography and compare with periapical radiographs (PR) to determine whether lamina dura (LD) and periodontal ligament (PDL) space can be detected and reported.

Study design: Sixty scans for anterior and posterior teeth with PR were included and scored on four point subjective scale. Scores assessed using Wilcoxon Signed rank test with the level of statistical significance P < 0.05.

Results: Maximum number of ties for LD in anteriors was seen in coronal section (16) and in posteriors with sagittal section (17). Assessing PDL space in anteriors, high number of ties was seen with coronal section (25) and sagittal section (21), while for posteriors showed a high number of ties in all sections.

Conclusions: LD could be observed and reported in coronal section for anteriors and in sagittal section for posteriors and PDL space in all the sections for both anteriors and posteriors.

Figure 1: Lamina dura (white arrow) and PDL space (blackarrow) observed in the anterior teeth as on the (a) periapicals and on the sections of cone beam computed tomography (b) coronal, (c) axial and (d) sagittal

Mentions: Periapical radiographs [Figure 1] were recorded on size 1 film (Ektaspeed Plus, Eastman Kodak, Rochester, USA) using Uni Bite holder (Dentsply India,). A Sirona dental unit (Heliodent Plus, Sirona Dental, Wasserfeldstraße 30, A-5020 Salzburg, Austria) operated at 65 kVp, 7.5 mA and 0.21 s, was used to exposing the films. The unit had a 0.7 mm focal spot and a 2 mm aluminum filter. The exposed films were processed in an automatic processing machine at 27°C with a 4.5 min processing cycle. The radiographs were viewed using a ×2 magnification with a constant light intensity.
