Charting and treatment planning basics (Case study): Dental assisting

Alejandra is a dental assistant working in a general dental practice with dentist Fred and is caring for Quinn, a 46-year-old patient who presents with intermittent sensitivity of the teeth on the lower right side. When caring for Quinn, Alejandra understands that charting and recording treatment are essential skills for dental assistants because accurate documentation supports patient safety, legal compliance, and continuity of care.

As part of the dental team, Alejandra promotes patient safety and quality care by observing and gathering information, preparing for and anticipating the needs of the patient and dentist, assisting the dentist chairside, monitoring patient responses, and documenting care.

In addition to these responsibilities, Alejandra ensures that all personal health information, or PHI, is handled confidentially and in compliance with the Health Insurance Portability and Accountability Act, or HIPAA for short. HIPAA is a federal law that protects PHI, which refers to any information about a patient’s past, present, or future health, as well as any information that can identify a patient, such as their name, birthdate, and contact information. Alejandra understands that the dental record is a confidential legal document, and that all entries must be accurate and complete, and that only authorized personnel may access or update them.

Alejandra begins observing and gathering information by reviewing Quinn’s dental record before the exam. She updates the health history by confirming that Quinn continues to take lisinopril daily for hypertension, and that there are no known allergies, health changes, or new medical alerts. When asked about his dental health, Quinn reports he has occasional sensitivity of the teeth on the lower right side. Alejandra documents the occasional sensitivity as his chief complaint in his dental history.

Alejandra then explains that she will be taking his vital signs before the clinical exam as part of standard patient assessment. After taking his blood pressure, pulse, temperature, and respirations, she enters this information into the dental record.

Next, Alejandra prepares and anticipates the clinical exam by reviewing the dental record and anticipating the need to document existing restorations and any areas that may need future treatment. She ensures the operatory setup supports efficient documentation by confirming that the correct charting system is open and that infection control protocols are in place for moving between chairside assisting and documentation tasks.

Then, she anticipates and organizes the sterilized instruments and equipment needed for Quinn’s exam. She prepares the mouth mirror, explorer, periodontal probe, and, due to Quinn’s report of sensitivity, cotton pliers, cold test materials, and a cotton roll. Before dentist Fred enters the operatory, she ensures Quinn is comfortably positioned semi-supine in the dental chair with the operator’s light on.

Now, to assist and implement safely, Alejandra ensures all the equipment is readily available for dentist Fred, listens carefully throughout the exam, and enters information into the dental chart using correct terminology, tooth numbers, and surfaces as dentist Fred dictates his findings. Alejandra understands that her role is not to diagnose the cause of Quinn’s sensitivity, but to accurately recognize and capture the information being discussed.

Dentist Fred: “Quinn, Alejandra told me you’re having some tooth sensitivity on the lower right side.”
