Dental assistants who want to perform expanded duties need to complete an appropriate course of training or education and then apply for certification in their specific area of expanded expertise through the Texas State Board of Dental Examiners:

  • Pit and Fissure Sealant
  • Nitrous Oxide Monitoring
  • Coronal Polishing
  • Registered Dental Assistant X-Rays

Dental assistants who have never taken x-rays before are permitted to take x-rays during their first year of employment. After their first year, or if they have previously taken x-rays in another state, dental assistants must register with the Board and obtain an X-Ray Certificate.

To perform expanded and advanced duties dental assistants have the option of obtaining the following certificates:

Pit and Fissure Sealant Certificate This certificate will allow a dental assistant to place pit and fissure sealants as well as cleanse the smooth and occlusal surfaces of teeth in preparation for this task or for the placement of orthodontic bonding resin. To obtain this, dental assistants will need to meet the following eligibility requirements:

  • Work as a dental assistant for at least two years
  • Complete a course in basic life support
  • Complete a course that is approved by the Board and accredited by the American Dental Association in pit and fissure sealants that is at least eight hours in length and includes study of the following subjects:
    • Infection control
    • CPR
    • Microbiology and chemistry
    • Dental anatomy
    • Jurisprudence and ethics related to pit and fissure sealants
    • Clinical lab for the application of sealants

There are currently eight dental assistant schools in Texas offering pit and fissure sealant training. Once dental assistants have completed these requirements they may fill out an Application for Pit and Fissure Sealant Certification and submit this along with a $30 application fee to the Texas State Board of Dental Examiners in Austin.

Coronal Polishing CertificateThere are three pathways to becoming eligible for this certificate, and all require dental assistants to have at least two years of work experience:

    • Complications, contra-indications, and indications of coronal polishing
    • Infection control procedures

Pathway 3

Once candidates have qualified they can complete an Application for a Coronal Polishing Certificate and return this plus a $12 application fee to the Texas State Board of Dental Examiners.

Nitrous Oxide Monitoring Certificate – Holding this certificate will allow dental assistants to monitor the administration of nitrous oxide. To be eligible, candidates must complete an approved course of education and submit an Application for a Nitrous Oxide Monitoring Certificate along with a fee of $12 to the Texas State Board of Dental Examiners.

  • Texas jurisprudence
  • Radiology
  • Infection control

Candidates who hold a current CDA (Certified Dental Assistant) credential from the Dental Assisting National Board may substitute this credential for a Board-approved class, however they must then also pass the Texas Jurisprudence Exam.

Once candidates have become eligible they can submit a Dental Assistant Registration Application along with a $36 application fee to the Board. This will be processed and if everything is complete and valid then the applicant will be issued an Activation Form with an accompanying pro-rated fee based on the applicant’s birth date. Once this Activation Form is returned and the fee paid, an applicant will become a Registered Dental Assistant with an X-Ray Certification. This must be renewed annually and expires on the dental assistant’s birthday.
