Objective:
Knowledge of oral disease prevention should lead to better oral health outcomes. The aims were to assess the association of dental knowledge and oral health.
Methods:
A random sample of 45-54 year-olds from Adelaide, South Australia, was surveyed in 2004/05. Oral examinations provided data on caries.
Results:
A total of 879 persons returned questionnaires (response=43.8%) with 709 (80.7%) examined. The majority rated 'seeing a dentist regularly' (63.0%), 'regular brushing of teeth' (92.5%) and 'using fluoride toothpaste' (52.2%) as 'definitely important' in preventing tooth decay. The percentage of persons who had a high knowledge of tooth decay prevention was 59.9%. Multivariate analysis controlling for sex, place of birth, education and income showed (p<0.05) associations of high dental knowledge of tooth decay prevention with fewer decayed teeth (β=-0.19) and more filled teeth (β=1.13).
Conclusions:
Dental knowledge was associated with oral health status.
Implications:
Conveying of information should be one part of oral health promotion actions to improve oral health.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
Assessment of the Mouth
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Oral Cavity
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
