2019 INFORMATICS INSERT 2

Dr Pranesh Silva is a dentist who lives and works in Ryeston, a country town in a remote part of Victoria. The town’s population is just over 20 000 people, many of whom have poor dental hygiene. Pranesh assumed that since his dental surgery has fewer than 1000 clients, residents must be visiting the only other dentist in town, Dr Carolyn Wisemann.

Recently, Pranesh and Carolyn met and chatted about the state of the town’s dental health. Pranesh was surprised to learn that Carolyn also has fewer than 1000 clients. They realised that since the nearest town and its dentist were more than an hour’s drive away, the majority of Ryeston’s residents were probably not receiving any professional dental care at all.

Carolyn wondered if the reason that people were not visiting a dentist was a lack of awareness about the importance of good dental hygiene. Pranesh suggested that they survey residents to find out. He believed that addressing this issue might boost client numbers for both businesses. To encourage participation in the survey, they would select a respondent’s name at random and offer a free teeth-whitening procedure.

Pranesh and Carolyn designed a survey that would be delivered in two ways:• online via a website, advertised in the local media and on posters around town• in person, speaking to people on the streets around town

The dentists and their staff will each carry a tablet computer and enter responses directly into the website as the residents answer their questions.Pranesh and Carolyn decided to gather data on the following items:• respondent’s name, address and phone number• how many fillings respondent has• current health of respondent’s teeth (self-assessed for online respondents)• respondent’s general health (self-assessed for online respondents)• how often respondent sees a dentist• a photograph of a smile showing respondent’s teeth, to measure tooth colour• respondent’s date of birth and age• how many times a week respondent: – brushes their teeth – flosses• how often respondent experiences toothaches

3 2019 INFORMATICS INSERT

After gathering and analysing their data, it became clear that there were residents who did not know how to care for their own or their families’ teeth, so the dentists decided to build a multimodal online solution (MMOS) to explain how to follow dental care routines and practices. As a part of this MMOS, Pranesh and Carolyn created a chart to demonstrate how awareness of dental care and the health of teeth relate to each other. They created a bubble chart like the one shown below, which displays de-identified information about each bubble when it is selected.
