The Oklahoma Pit and Fissure Sealants certification is an expanded duty permit designed specifically for Dental Assistants (DAs) and Certified Dental Assistants (CDAs) currently practicing in the state of Oklahoma.
This certification empowers dental assistants to take on higher-level responsibilities, specifically the placement of preventative sealants on the occlusal (chewing) surfaces of teeth.
This course and the subsequent exam are intended for dental professionals looking to advance their careers, increase their value to a dental practice, and play a more direct role in preventative patient care.
Earning this permit demonstrates proficiency in identifying eligible teeth and correctly applying sealant material to prevent dental caries (cavities).
The expanded duty course focuses on both the theoretical knowledge and practical skills required for safe and effective sealant placement. The curriculum is approved by the Oklahoma Board of Dentistry.
Key areas of study typically include:
Dental Anatomy and Physiology: Detailed review of tooth morphology, specifically focusing on the structure of pits, fissures, and occlusal surfaces.
Caries Formation and Prevention: Understanding the process of tooth decay and the role sealants play in cavity prevention.
Patient Selection and Evaluation: Learning the specific indications and contraindications for sealants (when they should and should not be placed).
Materials Science: Knowledge of different types of sealant materials (filled vs. unfilled, light-cured vs. self-cured) and their properties.
Clinical Technique: Step-by-step instruction on the correct application process, including:
Tooth preparation and cleaning
Isolation techniques (e.g., rubber dam, cotton rolls)
Etching and rinsing protocols
Sealant application and curing
Checking occlusion (bite) and adjusting as necessary
Infection Control and Safety: Adhering to strict sterilization and safety standards required in Oklahoma.
The final examination for the Oklahoma Pit and Fissure Sealants permit usually consists of two components:
This is a comprehensive, multiple-choice exam designed to test your theoretical knowledge of the course material.
You can expect questions covering anatomy, indications/contraindications, the scientific rationale behind each step of the process, infection control, and Oklahoma dental law relevant to expanded duties.
The passing score is typically 75% or higher.
The practical component requires candidates to demonstrate proficiency in applying sealants. This may be performed on a typodont (dental model) or, in some approved course settings, on a live patient under direct supervision.
Candidates are evaluated on their ability to isolate the tooth, etch correctly, apply the sealant material without voids or bubbles, cure the material properly, and check the final occlusion. The clinical portion is often graded on a pass/fail basis.
Success on the Oklahoma Pit and Fissure Sealants exam requires a combination of academic study and hands-on practice:
Review Course Materials Thoroughly: Your primary study resource should be the syllabus and textbooks provided during your Board-approved expanded duty course.
Utilize Practice Exams: Take advantage of practice questions that simulate the format and content of the written exam. Focus on understanding the rationale behind the correct answers.
Anatomy Drill: Dedicate time to reviewing dental anatomy, specifically mastering the identification of pits and fissures on different types of teeth.
Practice the Clinical Steps: If you have access to a typodont, practice the entire application sequence—isolation, etching, application, curing—until the movements are fluid and correct.
Infection Control Review: Do not neglect standard infection control protocols; they are critical for both the exam and daily practice.
In Oklahoma, the examination process is closely tied to the approved expanded duty course providers.
You must first complete a course approved by the Oklahoma Board of Dentistry. These courses are typically offered by:
Dental Assisting Schools: Many accredited dental assisting programs offer expanded duty certifications.
Community Colleges or Vo-Tech Centers: Institutions with established dental auxiliary programs often host these courses.
The Oklahoma Dental Association (ODA): The ODA or local dental societies sometimes provide these continuing education opportunities.
Upon successful completion of the course, the written and practical exams are usually administered by the same educational institution on behalf of the Board. Always verify the specific testing location and procedure with your course instructor.
Obtaining the Pit and Fissure Sealants expanded duty permit significantly enhances a dental assistant's professional standing in Oklahoma.
