Mitochondrial Function and Root-Filled Teeth - Detrimental and Unknown Interfaces in Systemic Immune Diseases

Area of Science:

• Biochemistry
• Immunology
• Dental Medicine

Background:

• Mitochondriopathy is increasingly linked to immune system disorders.
• The potential for root-filled teeth (RFT) to release toxins has been debated, but their impact on mitochondrial adenosine triphosphate (ATP) activity is under-researched.
• Limited methods exist for assessing toxin release from teeth.

Purpose of the Study:

• To investigate toxin release from RFTs.
• To determine the effect of RFT-derived toxins (Tox-sol) on mitochondrial ATP activity in patients.

Main Methods:

• Root-filled teeth (RFTs) were extracted and placed in an aqueous solution for 24 hours to create a toxin solution (Tox-sol).
• Toxin release was assessed using a volatile sulfur compound indicator (VSCI).
• Peripheral blood mononuclear cells (PBMCs) from patients were exposed to diluted Tox-sol (1:100), and changes in mitochondrial ATP activity were measured.

Main Results:

• Exposure to Tox-sol reduced overall ATP activity by approximately 10% in the study population (n=30).
• Three distinct patient responses were observed: significantly reduced ATP activity (n=16), neutral effect (n=10), and increased ATP activity (n=4).
• Non-disease-specific inhibition of ATP activity was noted in patients with rheumatism, neurological disorders, allergies, and tumors.

Conclusions:

• Toxins from RFTs can inhibit mitochondrial ATP activity, potentially contributing to mitochondriopathies.
• A practical VSCI effectively indicated toxic sulfur compounds released from RFTs.
• While disease-specific effects were not identified within the study's limitations, RFT toxins warrant further investigation as a factor in disease development.
