Mandibular tori, also known as torus mandibularis (singular) or tori mandibulares (plural), are bony growths that develop on the lower jaw, specifically on the lingual (tongue) surface of the mandible. These growths are benign, non-cancerous, and typically slow-growing. Here are some key characteristics and facts about mandibular tori:

1. Location:

   • Mandibular tori are most commonly found on the inner surface of the lower jaw, near the premolars and above the location of the mylohyoid muscle attachment.

2. Appearance:

   • They often present as bony, rounded protrusions or lumps.
   • Mandibular tori can vary in size and shape, and some individuals may have multiple tori.

3. Symmetry:

   • Tori are often symmetrical, meaning they appear on both sides of the lower jaw in a similar location.

4. Prevalence:

   • The prevalence of mandibular tori varies among populations. They are more commonly seen in adults and are often asymptomatic.

5. Causes:

   • The exact cause of mandibular tori is not fully understood. They are believed to have a genetic component, as they tend to run in families.

6. Gender and Ethnicity:

   • Mandibular tori are more common in certain populations and ethnic groups.
   • There is some evidence to suggest that mandibular tori are more prevalent in females than males.

7. Asymptomatic Nature:

   • In many cases, mandibular tori are asymptomatic and do not cause any pain or discomfort.
   • They are usually discovered incidentally during routine dental examinations or radiographic studies.

8. Challenges in Oral Care:

   • Mandibular tori may pose challenges in oral care, as they can make it difficult for individuals to wear dentures or dental appliances comfortably.

9. Treatment:

   • In most cases, no treatment is required for mandibular tori unless they interfere with oral function or cause discomfort.
   • If necessary, surgical removal can be considered, but it is typically performed only when the tori significantly impact oral health.

10. Differential Diagnosis:

    • Mandibular tori should be differentiated from other oral conditions, such as exostoses (bony growths) or other pathologies.

It’s important to note that while mandibular tori are generally benign and do not pose a health risk, any unusual growths or changes in the oral cavity should be evaluated by a dentist or oral healthcare professional. Regular dental check-ups can help monitor the presence and condition of mandibular tori and ensure overall oral health.
