ABOP Diplomate study guide
ABOP Diplomate · Work through your exam, one topic at a time.
The ABOP Diplomate Examination is the board certification pathway for dentists who have completed advanced training in oral and maxillofacial pathology and who wish to be recognized as diplomates of the American Board of Oral Pathology. It is intended for specialty-trained oral pathologists preparing for a career in diagnostic services, academic pathology, or hospital and reference-laboratory practice, and it tests whether a candidate can function as a consultant-level diagnostician rather than simply recall textbook lists. The ABOP Diplomate study guide has 10 sections and about 2,488 words.
01Oral and Maxillofacial Surgical Pathology
Surgical pathology of the head and neck requires a systematic approach: describe the specimen, orient it, sample margins, and correlate with imaging. Know the classic histologic features of squamous cell carcinoma variants (verrucous, spindle cell, basaloid, papillary), the distinction between dysplasia grades, and the significance of depth of invasion and worst pattern of invasion.
299 words, about 1 min02Oral and Maxillofacial Medicine and Mucosal Disease
Mucosal disease diagnosis rests on lesion morphology, duration, and systemic associations. Master the classification of white lesions (leukoplakia, lichen planus, frictional keratosis, chronic hyperplastic candidiasis, hairy leukoplakia), red lesions (erythroplakia, erythroleukoplakia), and ulcerative conditions (aphthous, herpes, pemphigus, mucous membrane pemphigoid, drug reactions).
258 words, about 1 min03Odontogenic Cysts and Tumors
Separate developmental from inflammatory cysts and benign from malignant odontogenic tumors. Key entities: radicular and dentigerous cysts, odontogenic keratocyst (OKC), lateral periodontal cyst, calcifying odontogenic cyst, and glandular odontogenic cyst.
270 words, about 1 min04Salivary Gland Pathology
Salivary neoplasms are organized by site and cell type. Benign: pleomorphic adenoma (most common, PAX3/PLAG1), Warthin tumor (parotid tail, smokers), oncocytoma, and basal cell adenoma.
265 words, about 1 min05Bone and Fibro-osseous Lesions of the Jaws
Distinguish fibro-osseous lesions from odontogenic and metastatic disease. Entities: fibrous dysplasia (GNAS), ossifying fibroma (conventional, juvenile trabecular, juvenile psammomatoid), cemento-osseous dysplasia (focal, periapical, florid), and osteosarcoma.
240 words, about 1 min06Head and Neck Soft Tissue Pathology
Soft tissue lesions of the head and neck span reactive, benign, and malignant entities. Know nodular fasciitis, fibromatosis, myofibroma, lipoma variants, schwannoma, neurofibroma, hemangioma, vascular malformations, and sarcomas (synovial sarcoma, rhabdomyosarcoma, angiosarcoma).
263 words, about 1 min07Hematolymphoid and Dermatologic Pathology of the Head and Neck
Recognize lymphoid proliferations and dermatologic lesions of the head and neck. Lymphoid: reactive hyperplasia, follicular hyperplasia, lymphoma (DLBCL, MALT, mantle cell, Hodgkin), and plasmacytic lesions.
229 words, about 1 min08Microscopic and Immunohistochemical Diagnosis
IHC is a tool for lineage confirmation, not a substitute for morphology. Understand antibody panels by lineage: epithelial (CK, p63, p40), mesenchymal (vimentin, SMA, desmin), neural (S100, SOX10), vascular (CD31, CD34, ERG), lymphoid (CD3, CD20, CD5, CD10, BCL2, cyclin D1), and melanocytic (S100, SOX10, Melan-A).
218 words, about 1 min09Laboratory Management, Quality Assurance, and Regulatory Compliance
Laboratory management covers quality control, quality assurance, proficiency testing, and regulatory compliance (CLIA, CAP). Know the difference between internal quality control (daily controls, calibration) and external quality assessment (proficiency testing).
228 words, about 1 min10Research Methodology, Biostatistics, and Evidence-Based Practice
Understand study designs (cohort, case-control, cross-sectional, RCT), measures of association (odds ratio, relative risk, hazard ratio), and measures of diagnostic accuracy (sensitivity, specificity, PPV, NPV, likelihood ratios). Know p-values, confidence intervals, and the difference between statistical and clinical significance.
