Background:
Due to anemia in thalassemia major (TM) and thalassemia intermedia (TI) patients, bone changes occur, especially in the broad bones like jaw and skull, which are the main sites of hematopoiesis. Therefore, the dentist should be aware of the disease to prevent complications. The aim of this study was to evaluate the radiographic findings of the jaw and teeth in TM and TI patients and to compare the two groups.
Methods:
50 TM patients and 50 TI patients in Amirkola Thalassemia Center, whose thalassemia were definitively diagnosed by a hematologist, were selected as the study group and the control group consisted of 50 healthy individuals. In patients` panoramic radiographs, dental anomalies (microdontia, root shortening etc.) and bone disorders (bone marrow hyperplasia, maxillary sinus invisibility etc.) were assessed. A p<0.05 was considered.
Results:
Dental anomalies were (42.84%) in TI patients and (23.46%) in the control group, the difference was significant. Dental anomalies in TM patients were (38.76%) and in the control group (23.46%) and a significant difference was observed (p<0.001). Bone disorders were (47.94%) in TI patients and in the control group (32.64%). Bone disorders in TM patients were (44.88%) and in the control group was (32.64%) that showed a significant difference.
Conclusion:
This study showed that in thalassemia patients, bone and dental disorders frequency were higher than healthy individuals. Bone disorders were also more common than dental anomalies. Dental and bone disorders were more common in TI.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
01:27Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
