Normal, inflammation and necrosis pulp radiograph image using 3D cone beam computed tomography

Abstract

Introduction: Abnormalities of the dental pulp can have several different diagnoses. Therefore, the dental pulp characteristics must be known in more detail and clear so that diagnosis be established more precisely and accurately. One characteristic of the pulp can be seen from the density value through the 3D Cone Beam Computed Tomography (3D CBCT). Methods: The study was conducted with a simple descriptive method. The population is all the data 3D CBCT of patients who visited the Universitas Padjadjaran Dental Hospital (RSGM Unpad) in 2012. Samples of the research were 75 pulps with normal, inflammation, and necrosis conditions and calculate the average density value. Results: Density values for dental pulps in the normal teeth between 465 - 775 HU, the inflammation teeth between 243.5 - 396 HU, and necrosis teeth between - 461.5 - -170 HU. Conclusion: There are differences in dental pulp density between the normal pulp, inflammation and necrosis through 3D CBCT.

Assessment of Pulpal Status in Primary Teeth Following Direct Pulp Capping in an Experimental Canine Model

“…Pulp density measurements performed comparatively on the axial CT images in the DPC teeth and their corresponding control groups ( Figure 5 ) revealed the following average values (Hounsfield units, HU): 804 = 328.87 HU, 704 = 506.25 HU; 806 = 579.12 HU, 706 = 698.37 HU; 807 = 694.37 HU, 707 = 622.62 HU ( Table 2 ). According to the reference intervals for normal/inflamed/necrotized pulp by Pramanik et al (2016) [ 27 ] and Marzook et al (2010) [ 28 ], six out of eight teeth in the CH group (804) and two out of eight teeth in the MTA group (806) exhibit pulp inflammation, while the Biodentine TM group (807) and all control groups (704, 706 and 707) exhibit normal pulp.…”

“…HU is the standard numeric value representing the relative density of body tissues according to a calibrated grey-level scale based on values for air (−1000 HU), water (0 HU) and bone density (+1000 HU) [ 41 ]. The density of the dental pulp ranges from −461.5 HU to −170 HU in the case of pulp necrosis, 243.5 HU −396 HU in pulp inflammation and 465 HU −775 HU when the pulp is healthy (with an average of 520 HU for coronal pulp and 892 HU for radicular pulp) [ 27 , 28 ]. The values obtained in our study are indicative for pulp inflammation in most of the CH-capped teeth, and all Biodentine TM -capped teeth and all the teeth in the three corresponding control groups are indicative for healthy pulp in most of the MTA-capped teeth.…”
