Background: This case report demonstrates the value of ultrasound measurements, and immunological and toxicological diagnostics in addition to current x-ray imaging procedures to diagnose hidden oral and maxillofacial infections. Using a clear scheme shows the procedure of the authors' steps. The positive impact on the patient's dermatological clinical picture is shown. Functional regeneration using metal-free ceramic implants and autologous bone augmentation is demonstrated. After a healing period, a postoperative control took place. Question: Are chronic inflammatory and chronic toxic stressors from the oral region affecting the patient's state of health and dermatological symptoms? Patients and Methods: A 52 year old female suffering from neurodermatitis, who had been therapy-resistant for several years, was rehabilitated by oral surgery and prosthetics. Radiological examinations with orthopantomogram (OPG) and three-dimensional imaging (DVT/CBCT) were inconclusive for possible jawbone inflammatory sites. Immunological, toxicological diagnostics and trans-alveolar bone densitometry with ultrasound (TAU), were able to show immunological and toxicological stressors and areas of reduced bone density. Bone densitometry with ultrasound raised the suspicion of silent inflammations in the jawbone with potentially increased cytokine levels. Results: For the patient incompatible materials, teeth with increased toxin exposure and surrounding softened, fatty, ischaemic bone was removed. Histologies and cytokine profiles were obtained. The resulting defects were functionally regenerated using ceramic implants and autologous augmentation. The cytokine profiles showed significantly elevated RANTES/CCL5, confirming the need for surgical intervention. The patient's atopic dermatitis improved significantly in this case. Summary: Individualized immunological and toxicological diagnostics and trans-alveolar bone density bone densitometry with ultrasound (TAU) identified immunological and toxicological stressors as well as reduced bone density with increased cytokine levels. A therapy-resistant neurodermatitis improved significantly after treatment. Conclusion: This case report illustrates the need for patient-specific and individualized examinations that link dentistry more closely with other medical conditions in order to clarify possible interactions.
