  Dental Hygienists
  • Decide which instruments to use to conduct dental procedures using well-defined dental hygiene practice standards. (1)
  • Decide which dental treatments to administer. for example, they may decide to apply sealants to children's molars to prevent tooth decay. although sealants are helpful to prevent tooth decay, they should not be applied unnecessarily since they are costly and once initiated, must be reapplied regularly. dental hygienists follow standard criteria for applying sealants and consider their previous experience to guide decision making. (2)
  • Decide the type, intensity and frequency of treatments. for example, they decide whether to schedule cleanings at three, six, or nine month intervals depending on patients' oral health, oral hygiene and financial means. they are guided by their professional training and practical experience when determining recall and treatment schedules. (2)
  • May decide where to place the brackets for braces on patients' teeth according to well-defined dental hygiene practice standards. if dental hygienists place brackets incorrectly, there could be significant loss of money, time and credibility of the dental hygienists as well as their practices.

  • Use spreadsheet software. for example, they may use excel spreadsheets to prepare schedules or to present fee guides for their patients. (2)
  • Use database software. for example, they use dental management practice software to enter patient data such as dental treatments provided, dental caries noted and patient appointments scheduled. (2)
  • Use communications software. for example, they use e-mail to correspond with co-workers and colleagues about patient and professional development matters. they communicate with members of professional development committees to plan continuing education workshops. (2)

  Note: This is an important skill
  Dental Hygienists
  • Evaluate patients' oral and dental health and identify treatment needs. they examine the anatomy of the mouth and look for calcium deposits, bleeding and infections. they examine the status of the gums, tongue, mouth floor, lymph nodes and glands to identify abnormalities and changes from previous visits. they note any changes, discuss them with patients and communicate any immediate concerns to both patients and dentists. accurate assessments are important so that patient dental problems are identified and addressed as soon as possible. dental hygienists in community settings may conduct dental risk assessments to target the most high-risk children for treatments. (2), (daily)
  • Evaluate the appropriateness and risks of particular anaesthetics, antibiotics and fluoride treatments for patients. they consider patients' overall health, the length of appointments and the location of the teeth being treated before conferring with dentists to confirm their assessments. (2)
  • May make preliminary assessments of patients' suitability for orthodontic treatments. they consider the results of orthodontic evaluations, patients' oral hygiene and patients' motivation to undergo treatment. dental hygienists share their findings with dentists who make the final assessments of patients' suitability for orthodontic treatments. (2)
  • Assess the need for fluoride applications. they consider patients' past restorative histories and the amounts of root exposure to determine if fluoride should be applied at home as well as in dentists' offices. fluoride treatments are important for preventive dental care. (2)
  • May assess the effectiveness of community dental health programs. they may analyze and monitor service utilization and dental status statistics to determine if there are changes in children's dental risk level scores. they may also consider input from parents, teachers, dentists and colleagues. gathering and assessing quantitative and qualitative data is essential to the continued support of many public health programs.

Dental hygienists work with dentists to provide oral care and dental hygiene. they assess patients' oral health and conduct dental hygiene treatments independently; however, assessment conclusions are often approved and confirmed by dentists. dental hygienists in some community health programs coordinate work teams, such as school dental clinic teams and work with other health professionals to provide health education sessions. dental hygienists may be assisted by dental assistants and administrative staff.



Continuous Learning

Desired Skill Level Range: 3

Dental hygienists set their own learning goals and take advantage of a variety of continuing education activities. they take continuing education courses offered by their professional associations or learning institutions and may participate in accredited study groups. they read medical textbooks, clinical journals and newsletters and access medical, dental hygiene and dental hygiene supplier web sites. dental hygienists are registered by their provincial regulatory bodies. in some provinces and territories they must complete mandatory continuing education credits to maintain certification.



Other Information

Desired Skill Level Range: N/A

Dental hygienists sometimes work in uncomfortable positions, sitting on high chairs for long periods, leaning over patients and performing many repetitive hand movements. they must pay attention to posture and correct body position in order to avoid neck and shoulder strain. fine dexterity and hand-eye coordination are required to perform precise oral dental hygiene interventions using instruments and equipment. they require upper limb co-ordination to perform dental hygiene functions, to place radiation protective aprons over patients and adjust overhead lights and multiple limb co-ordination to roll about on stools. in some situations they carry medium loads such as display boards, handouts and portable dental equipment such as chairs, stools, supply kits and instruments. dental hygienists use their olfactory senses to identify potential health conditions such as diabetes. they also need visual acuity to identify suspicious soft tissue conditions in patients' mouths.

Dental hygienists must be patient, friendly, non-judgemental, compassionate, empathetic and relate to other people well.

Increased use of computers and improved diagnostic technologies may increase the importance of computer skills. ongoing changes in dentistry will require continued emphasis on continuous learning. increases in naturopathic treatments for oral and overall health will also require continuous learning and updating of skills.
