Summary
Multiple idiopathic apical root resorption (MIARR) is a rare dental condition affecting permanent teeth. This case highlights a 16-year-old boy with MIARR, emphasizing its potential for pain and mobility.
Area of Science:
- Dentistry
- Oral Pathology
Background:
- External root resorption (ERR) in permanent teeth is a complex process with numerous known causes.
- When etiological factors are absent, it is classified as idiopathic root resorption, either cervical or apical.
- Multiple idiopathic apical root resorption (MIARR) is an uncommon manifestation of this condition.
Observation:
- This report details a rare case of MIARR in a 16-year-old male patient.
- The condition was identified radiographically.
- MIARR can affect single or multiple teeth.
Findings:
- The patient presented with multiple idiopathic apical root resorption.
- The diagnosis was made after excluding common causes of external root resorption.
- Idiopathic root resorption can manifest as apical or cervical resorption.
Implications:
- Early detection of MIARR is crucial, often identified incidentally via radiography.
- Severe cases of MIARR may lead to symptoms such as tooth pain and mobility.
- Understanding idiopathic root resorption aids in differential diagnosis and patient management.

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

03:02Primary and Secondary Growth in Roots and Shoots
Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.
01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
02:34Water and Mineral Acquisition
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.
01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
