*3.2. Gingivitis*

Table 4 shows the prevalence of gingivitis in the Australian dentate adult population. Overall, 28.8% of Australian dentate adults aged 15 years and over had gingivitis. Although the prevalence of gingivitis was decreasing with age across the four age groups, the differences were not statistically significant. Among all age groups, males had the highest prevalence of gingivitis (34.7%) and females the lowest (23.1%). In addition, those who usually visited a dentist for a dental problem (33.2%) had a greater prevalence of gingivitis than their counterparts.
