OMS study guide
OMS · Work through your exam, one topic at a time.
The OMS exam is a multiple-choice assessment built around oral and maxillofacial surgery and the disciplines that surround it in everyday practice. Candidates are typically dentists preparing for a scope-of-practice or specialty-adjacent credential, or clinicians who want an independent check of their knowledge across surgical, medical, and restorative topics. The OMS study guide has 10 sections and about 2,731 words.
01Oral and Maxillofacial Surgery
The OMS section tests surgical judgment rather than memorized procedures: when to operate, how infection and trauma behave anatomically, and how to protect the airway and inferior alveolar nerve. Questions often present a radiograph description, a swelling, or a trauma scenario and ask for the next safest step.
327 words, about 2 min02Anesthesia and Pain Management
Anesthesia and pain management tests pharmacology, block selection, sedation depth, and rescue from local anesthetic systemic toxicity (LAST). The exam favors dose calculations and 'what went wrong' scenarios over drug lists.
300 words, about 2 min03Pathology and Oral Medicine
Pathology and oral medicine tests pattern recognition plus the discipline to biopsy when a lesion does not behave. Expect mucosal ulceration, white and red patches, vesiculobullous disease, odontogenic cysts and tumors, salivary disease, and oral manifestations of systemic disease.
292 words, about 1 min04Radiology and Imaging
Radiology and imaging tests justified image selection, systematic interpretation, and recognition of what each modality cannot show. The exam emphasizes panoramic and CBCT limitations, caries and periapical diagnosis, and incidental findings.
284 words, about 1 min05Periodontics and Implantology
Periodontics and implantology tests diagnosis by staging and grading, nonsurgical and surgical therapy, implant site assessment, and long-term maintenance. The exam expects risk-based decisions, not just pocket depths.
254 words, about 1 min06Endodontics
Endodontics tests diagnosis, shaping and disinfection, obturation, restoration, and retreatment decisions. The exam rewards a clear pulpal and periapical diagnosis and safe management of complex anatomy.
261 words, about 1 min07Prosthodontics and Restorative Dentistry
Prosthodontics and restorative dentistry tests material selection, preparation design, occlusion, and treatment sequencing for crowns, bridges, removable prostheses, and implant restorations. Preparation follows retention, resistance, and preservation of tooth structure.
247 words, about 1 min08Orthodontics and Pediatric Dentistry
Orthodontics and pediatric dentistry tests growth, eruption, space management, interceptive treatment, behavior guidance, and prevention. The exam connects timing to the developing dentition.
266 words, about 1 min09Patient Assessment, Diagnosis, and Treatment Planning
Patient assessment, diagnosis, and treatment planning tests whether you can gather data, form a prioritized problem list, and sequence care safely. The exam favors cases with medical comorbidity, conflicting findings, and consent issues.
256 words, about 1 min10Medical Emergencies and Infection Control
Medical emergencies and infection control tests recognition, immediate action, and prevention. The exam expects you to distinguish common vasovagal events from true emergencies and to apply standard precautions consistently.
