Macroscopic and radiographic analysis of primary teeth with hyperbilirubinemia in children with chronic liver disease and liver transplantation
Aim: is to identify, through macroscopic and radiographic analysis, structural changes in dental tissues affected by hyperbilirubinemia, usually seen from the clinical sign of icterus and causes the development of intrinsic greenish pigments in dental structure. Materials and Methods: The sample con...

| Resumo: | Aim: is to identify, through macroscopic and radiographic analysis, structural changes in dental tissues affected by hyperbilirubinemia, usually seen from the clinical sign of icterus and causes the development of intrinsic greenish pigments in dental structure. Materials and Methods: The sample consisted of 31 primary teeth divided into a control group (n=7) and an experimental group (n=24). Macroscopic analyzes were performed using standardized individual photographs and radiographic ones obtained by image acquisition at 9 mA, 70 kVp, 8cm distance, 0.4 seconds exposure and with XDR Sensor®. The images were converted by XDR Brasil 3.1.6 software and standardized by GIMP 2.10.22 software. The Histogram’s simple mean data were analyzed by T-Student and Mann-Whitney tests (p<0.05). Results: showed intensity of pigmentation in the cervical region of the root, with a statistically significant difference in the root portion between the experimental and control groups (p=0.043. In the analysis of radiographic density of the root structure of the experimental group, there was a statistically significant difference (p= 0.016) between the cervical and apical thirds. Discussion: The data showed that teeth pigmented by hyperbilirubinemia do not have changes in mineral density in the coronary thirds. Conclusion: Greenish pigments teeth have differences in radiographic density only in the root structure. |
