What the Course Entails and Exam Details

The certification requires completion of a state-approved course, often consisting of 14 hours of combined didactic and clinical training. The curriculum covers a wide range of essential topics, including:

• The properties and formation of plaque, calculus, and dental stains (intrinsic vs. extrinsic).

• Detailed tooth anatomy and oral morphology, specifically concerning coronal polishing.

• The characteristics and indicators of healthy gingival tissue.

• Various polishing agents, their abrasiveness, and indications and contraindications for use.

• The full coronal polishing procedure: armamentarium, tray set-up, equipment care, and technique (handpiece speed, fulcrum use, and patient positioning).

• Rigorous infection control protocols.

• Patient management, health histories, and handling medically compromised patients.

• Patient education regarding oral hygiene.

What to Expect in the Final Exam

The final exam is a written review of the core knowledge acquired. Students should expect:

• Format: The exam typically features multiple-choice and true/false questions. It assesses the candidate's understanding of theory, safety, and correct procedure.

• Passing Score: While specific percentage requirements can vary by course provider, students are generally expected to pass with a score that demonstrates competency, often in the range of 70-75% or a "Pass" designation.

• Time Limit: The duration for the final exam varies but is designed to allow students adequate time to complete the multiple-choice assessment. It is not an excessively long exam but requires a systematic approach.

• Rules: The exam focuses on legalities, such as understanding what procedures are legal for dental assistants versus hygienists, the direct supervision required by a dentist, and adherence to infection control.

How to Study and Exam Centers

How to Study

Success on the Oklahoma Coronal Polishing State Exam relies on both academic review and practical skill. Follow these strategies:

• Review Course Materials: Go over textbooks, lecture notes, and provided handouts from your state-approved course. Focus on stain classification, contraindications, and anatomical landmarks.

• Engage in Practice: Practice the technique on a manikin or classmate under instructor supervision. Perfect your fulcrum and handpiece control.

• Form Study Groups: Collaborating with peers allows you to quiz each other and discuss tricky topics like patient scenarios and emergency procedures.

• Take Mock Exams: Utilize practice exams or flashcards to familiarize yourself with the question types and formatting. This is one of the most effective ways to identify weak areas.

Exam Centers

The written exam component is typically proctored in person, following the completion of your clinical course. For specific information about exam centers and online portals, consider the following options:

• Authorized Training Schools: The exam is often administered at the CODA-accredited or Oklahoma Board-approved schools and technology centers where you complete the coronal polishing course.

• Authorized Proctoring Locations: Testing centers at various universities and colleges throughout Oklahoma, such as Rose State College or Oklahoma State University (OKC), may offer proctoring services for expanded function exams. Always confirm with your course provider and the testing site for scheduling and required proctoring fees.
