Alternative Terms for Dental Mass
A dental mass is most commonly referred to as an "odontogenic tumor," "odontogenic cyst," or "jaw lesion" in clinical practice and pathology reporting. 1, 2
Primary Terminology Categories
Odontogenic Lesions
The umbrella term "odontogenic lesions" encompasses all masses arising from tooth-forming tissues and includes both cystic and solid variants. 2, 3, 4
- Odontogenic cysts: Fluid-filled lesions derived from odontogenic epithelium (reduced enamel epithelium, epithelial cell rests of Serres, epithelial cell rests of Malassez) 5
- Odontogenic tumors: Solid or mixed lesions arising from dental developmental tissues 2, 3
- Odontogenic neoplasms: Used interchangeably with odontogenic tumors to emphasize the proliferative nature 4
Anatomic Descriptors
When location is emphasized, alternative terms include:
- Jaw mass: Generic term for any mass in the mandible or maxilla 3
- Mandibular mass or maxillary mass: Site-specific designations 1
- Intraoral mass: When the mass is accessible through the oral cavity 1
- Dentoalveolar mass: When involving both teeth and alveolar bone 1
Pathology-Specific Terms
Cystic lesions are described as:
- Jaw cyst 2
- Dentigerous cyst (when associated with unerupted tooth crown) 5
- Odontogenic keratocyst (for specific aggressive variants) 2
Solid lesions may be termed:
- Odontoma (when composed of dental tissues) 6
- Ameloblastoma (for epithelial tumors) 4
- Fibroosseous lesion (when involving fibrous and bony components) 2
Clinical Context Matters
The American Academy of Otolaryngology-Head and Neck Surgery guidelines emphasize that when a dental mass presents as part of a neck mass, it should be distinguished from metastatic disease or lymphadenopathy. 1 The 2017 guidelines specifically note that masses originating from "mandibular or dental pathology" require separate management algorithms from other neck masses. 1
Important Caveat
Never confuse a dental mass with a neck mass from head and neck squamous cell carcinoma (HNSCC). 1 While both may present in the oral cavity or jaw region, dental masses arise from odontogenic tissues, whereas HNSCC arises from mucosal epithelium and may invade bone secondarily. 1 The distinction is critical because HNSCC carries significant mortality risk and requires urgent oncologic management. 1
Reporting Standards
According to Modern Pathology guidelines for oral cavity specimens, pathology reports should specify: 1
- Tumor description: Size (three dimensions), shape (ulcerating, exophytic, polypoid), color, necrosis 1
- Anatomic designation: Specific oral cavity/oropharynx subsites involved 1
- Relationship to dental structures: Involvement of cortical bone, tooth socket, or alveolar ridge 1
The term "dental mass" itself is relatively informal; formal pathology and radiology reports favor precise terminology like "odontogenic cyst" or "odontogenic tumor" with specific subtype classification. 2, 3, 4
