The cause may be aseptic. Diagnosis
Diagnosis is usually apparent on MRI although plain X-rays and CT examinations can be suggestive. The MRI will reveal air changes in the disc and possibly even external involvement involving the bone or epidural regions. A biopsy may be performed and helps with diagnosis in some cases but often an organism is not obtained. C-reactive protein levels and ESR levels will be elevated and are useful for treatment. Often, the white blood cell count will be normal and the patient will be afebrile. Treatment
Treatment usually includes antibiotics, and reducing the mobility of the affected region, either with a back brace or a plaster cast. Without treatment, the patient may form an abscess which may need to be surgically corrected. Due to the poor vascularity of the disc, drugs required for treatment often include potent agents such as Ciprofloxacin along with Vancomycin. Occasionally, oral drugs can be used to treat the infection but it may fail and IV drugs may be required. If the patient is an adult many surgeons and doctors now  recommend moving little and often and within the pain limits of the medication. Discs respond to osmotic pressure therefore movement is beneficial to increase their blood flow and fluid dynamics. This is why disc patients are no longer told to bed rest. In children whether to bed rest or move a little is decided on an individual basis, depending on the site and severity of the discitis. References

Torus mandibularis is a bony growth in the mandible along the surface nearest to the tongue. Mandibular tori are usually present near the premolars and above the location of the mylohyoid muscles attachment to the mandible. In 90% of cases, there is a torus on both the left and right sides. The prevalence of mandibular tori ranges from 5-40%. It is less common than bony growths occurring on the palate, known as torus palatinus. Mandibular tori are more common in Asian and Inuit populations, and slightly more common in males. In the United States, the prevalence is 7-10% of the population. It is believed that mandibular tori are caused by several factors. They are more common in early adulthood and are associated with bruxism. The size of the tori may fluctuate throughout life, and in some cases the tori can be large enough to touch each other in the midline of mouth. Consequently, it is believed that mandibular tori are the result of local stresses and not due solely to genetic influences. Mandibular tori are usually a clinical finding with no treatment necessary. It is possible for ulcers to form in the area of the tori due to trauma. The tori may also complicate the fabrication of dentures. If removal of the tori is needed, surgery can be done to reduce the amount of bone, but the tori may reform in cases where nearby teeth still receive local stresses. References
