Abstract
A physically independent and mentally competent 61-year-old gentleman was diagnosed with left upper alveolar spindle cell carcinoma. He underwent left infrastructure maxillectomy with reconstruction and had bismuth iodoform paraffin paste packed in the post-operative cavities. The patient subsequently exhibited labile emotions and acute delirium. Further investigation showed that his urine iodine level was highly elevated. He eventually made a full recovery and returned home.

Sci Rep 2023; 13:9738.

Abstract
Calcium silicate-based materials are used to block the communication between the root canal and the periodontal ligament space. This brings the materials into contact with tissues and the potential for local and systemic elemental release and movement. The aim of the study was to evaluate the elemental release of bismuth from ProRoot MTA in contact with connective tissues after 30 and 180 days as well as any accumulation in peripheral organs using an animal model. Tricalcium silicate and hydroxyapatite containing 20% bismuth oxide (HAp-Bi) were used as controls. The null hypothesis was that bismuth migrates from tricalcium silicate-based materials when associated with silicon. The materials were examined using scanning electron microscopy, energy dispersive spectroscopy (SEM/EDS) and X-ray diffraction prior to implantation as well as using SEM/EDS, micro X-ray fluorescence and Raman spectroscopy after implantation to assess elemental presence in surrounding tissues. Histological analysis was used to evaluate the changes in tissue architecture and inductively coupled plasma mass spectrometry (ICP-MS) was used to investigate the elemental deposition. For the systemic investigation, routine blood analysis was performed and organs were obtained to evaluate the presence of bismuth and silicon using ICP-MS after acid digestion. In the histological analysis of the implantation sites, macrophages and multinucleated giant cells could be observed after 30 days which after 180 days became a chronic infiltrate; although, no major differences were identified in red and white blood cell analyses and biochemical tests. Implantation altered the materials as observed in the Raman analysis and bismuth was detected both locally and within kidney samples after both periods of analysis, indicating the potential for accumulation of bismuth in this organ. Smaller amounts of bismuth than observed in the kidney were also detected in blood, liver and brain for the ProRoot MTA and HAp-Bi after 180 days. Bismuth was released from the ProRoot MTA locally and was detected systemically and in samples without silicon; thus, the null hypothesis was rejected. The bismuth release demonstrated that this element accumulated both locally and systemically, mainly in the kidneys in comparison with brain and liver regardless of the material base.

Abstract
Amelogenesis imperfecta (AI) is a hereditary condition that affects the clinical features and structure of the enamel. The enamel formation diseases are inherited and might be X-linked, autosomal dominant, recessive, sex-related, or sporadic. Dental professionals should evaluate such patients completely, both clinically and radiographically, to detect any cysts associated with impacted or unerupted teeth. This report describes the case of a 10-year-old patient affected by amelogenesis imperfecta with a dentigerous cyst involving an impacted tooth and an unerupted tooth of the maxilla.
