Lesions of the jaws

Area of Science:

• Oral and Maxillofacial Pathology
• Developmental Biology
• Skeletal Biology

Background:

• Jaw bones possess unique embryological origins, primarily from cranial neural crest ectomesenchyme, distinguishing them from other skeletal elements.
• The presence of teeth within the jawbones is a key factor leading to specialized pathologies not found in other bones.

Purpose of the Study:

• To provide a comprehensive review of jaw bone lesions.
• To focus on odontogenic cysts and tumors as the primary topic.
• To include other significant jaw-confined lesions such as giant cell lesions, fibro-osseous lesions, and melanotic neuro-ectodermal tumor of infancy.

Main Methods:

• Literature review of existing studies on jaw bone pathologies.
• Classification and discussion of various odontogenic and non-odontogenic jaw lesions.
• Emphasis on the unique characteristics and origins of these lesions.

Main Results:

• Odontogenic cysts and tumors represent a significant category of jaw bone lesions due to the presence of teeth.
• Other notable jaw lesions include giant cell lesions, fibro-osseous lesions, and melanotic neuro-ectodermal tumor of infancy.
• The embryological derivation of jaw bones influences the types of lesions observed.

Conclusions:

• Jaw bones exhibit a unique spectrum of lesions, predominantly odontogenic in nature, stemming from their distinct developmental pathways and dentition.
• Understanding these specialized pathologies is crucial for accurate diagnosis and management in oral and maxillofacial regions.
• This review consolidates knowledge on key jaw bone lesions for researchers and clinicians.
