Introduction

Dental assistants assist dentists during the examination and treatment of patients and perform clerical functions.

Note: Each essential skills task is followed by a number in brackets, e.g. (2), which is the estimated complexity level for that task. Tasks are assigned levels, ranging from Level 1 (basic task) to Levels 4 or 5 (advanced task), and are listed in increasing order of complexity. The complexity levels may vary based on the requirements of the workplace.

Additional Information

Other Essential Skills:

Working with Others

Dental assistants perform some tasks independently but coordinate their work with that of dentists, dental hygienists and receptionists. They spend most of their time working with dentists, assisting with dental procedures. They spend part of each day working independently, mixing materials, preparing instruments and completing housekeeping related tasks.

Continuous Learning

Dental assistants have an ongoing need to learn. They learn about new products and dental procedures. Some obtain continuing education credits through training offered by colleges and universities. Some obtain new information by attending courses or meetings conducted by dental associations, private companies or dental study clubs.

Impact of Digital Technology

All Essential Skills are affected by the introduction of technology in the workplace. Dental assistants’ ability to adapt to new technologies is strongly related to their skill levels across the Essential Skills, including reading, writing, thinking and communication skills. Technologies are transforming the ways in which workers obtain, process and communicate information, and the types of skills needed to perform in their jobs. For example, specialized software and electronic equipment is now commonplace in dentistry. Dental assistants require specialized skills to operate this equipment. They also need computer skills to access information over the Internet and to communicate with co‑workers and suppliers. Moreover, in addition to reading manuals to learn how to operate machines, such as extractors, workers can learn by viewing self‑help tutorials and multimedia presentations available in DVD and online formats.

Technology in the workplace further affects the complexity of tasks related to the Essential Skills required for this occupation. Dental assistants need the skills to use increasingly complex technology, such as dental management software and computerized equipment. For example, they may operate electronic dentistry systems - which include air and water syringes, saliva ejectors and evacuators - and handle electronic sanitization equipment, such as dry heat sterilizers and cage washers. Tasks previously done manually, such as entering dates, times and amounts into bills, calculating material requirements or determining the amount of change to provide on cash transactions, are completed with speed and accuracy using specialized dental software applications, calculators and point‑of‑sale equipment. In addition, the use of electronic databases and keyword search functions can assist in locating product information, such as prices and inventory counts.
