Technical note: Stafne static mandibular bone defect-further expression on the buccal aspect of the ramus

Area of Science:

• Anatomy
• Epidemiology
• Parasitology

Background:

• Stafne static mandibular bone defect (SSBD) is a common entity.
• Its precise anatomical relationship with salivary glands is not fully elucidated.
• Global prevalence and potential etiological factors require further investigation.

Purpose of the Study:

• To describe a cavitation defect on the buccal ramus of the mandible.
• To correlate the anatomical placement of SSBD with major salivary glands.
• To investigate the global latitudinal variation in SSBD prevalence and its association with parasite load.

Main Methods:

• Anatomical description of a novel SSBD variant.
• Correlation analysis between SSBD location and salivary gland proximity.
• Statistical analysis of global prevalence data in relation to latitude and parasite load.

Main Results:

• SSBD correlates precisely with submandibular and parotid salivary glands, suggesting increased salivary gland size.
• Global prevalence ranges from 10% in tropics to near 0% in the Arctic.
• A direct correlation exists between SSBD prevalence, parasite load, and diversity.

Conclusions:

• SSBD anatomical location supports its association with major salivary glands.
• Latitudinal variation in SSBD prevalence suggests environmental influences.
• SSBD may serve as a marker for historical enteric macroparasite infestation.
