Background. To determine the demographic profile and practising arrangements of general dentists in New Zealand. Methods.
A questionnaire comprising 19 sections with 125 questions was distributed via mail to 351 general dentists in New Zealand
who were selected, at random, from the Dental Council of New Zealand’s 2016 register. Results. Two hundred and four
questionnaires were returned, of which 188 were usable giving a response rate of 53.5%. e majority of the respondents

a wide geographic distribution. Sole practitioners accounted for 24.1% of respondents, with the mean number of dentists per
practice being 3.2. e majority of respondents (71.6%) attended five or more continuing professional development courses in
the past year. Ninety-one percent of respondents used a computerized management system, and 95.3% used the Internet. e
use of nickel-titanium endodontic files (83.9%) and digital imaging (82.2%) was the most frequently cited clinical innovations.
Articaine was the most popular local anaesthetic of choice. Conclusions. Dentistry is an ever-changing profession, with
evidence that NZ dentists continue to develop, learn, and embrace advancements in technologies to supply high-quality
evidence-based treatment.
1. Introduction
Patterns of dental disease have changed dramatically over
the past quarter century. Public awareness of the benefits
of good oral health has increased, and the impact of ad-
vances in personal and public prevention strategies, in-
cluding fluoride toothpaste and fluoridated water supplies,
is now being realised. Although the amount of simple
treatment provided is declining, the amount of complex
treatment required and provided is correspondingly in-
creasing [1]. With the increase in average life expectancy,
adults are retaining more of their natural dentition for
longer, guiding the strategic vision for oral health to be
focused on “good oral health, for all, for life” [2, 3]. e
changing oral health needs of the population highlight the
task at hand for the dental profession in treating dental
disease and maintaining oral health and quality of life for
patients. In addition, patients now have a greater aware-
ness of dental aesthetics and expect to remain dentate
throughout life.
Dentistry is a commercialised profession, which is re-
flected in a number of ways such as the growing number of
postgraduate courses, business aspects of dentistry, and
marketing of alternative forms of treatment and materials.
With the proliferation of digital technology over the past ten
years, a new “communication culture” has also emerged.
Due to the attractiveness and popularity of social media,
many dental schools also use social media to promote their
courses and communicate with their students [4]. In ad-
dition, social media have been used to promote new dental
technologies and advertise private dental practices, as well as
to share dental research [5]. e degree to which social
media is used by general dentists is an area that has to date
been poorly investigated.
