Purpose:
To investigate oral health behaviour and smoking habits among academic staff members in Iran's dental schools in relation to their personal and academic background characteristics.
Materials And Methods:
Out of 15 state dental schools, seven were selected randomly as clusters. All of the educators who were present (total n = 363) were asked to voluntarily fill in a self-administered pre-tested questionnaire. In addition to background and academic characteristics, the questionnaire requested information on smoking habits, oral self-care, and dental check-ups. Recommended oral self-care was defined as brushing at least twice a day and frequent use of fluoridated toothpaste. Chi-square test and binary logistic regression model served for statistical analyses.
Results:
A total of 291 educators filled in the questionnaire (response rate = 80%). Women reported higher frequencies of brushing (p = 0.001), use of fluoridated toothpaste (p = 0.002), flossing (p < 0.01) and eating sugary snacks (p = 0.01) compared with men. Habitual cigarette and pipe smoking was reported by 22% and 3% of male educators respectively. Familiarity with the field of oral public health correlated to higher frequencies of brushing (p = 0.05) and flossing (p = 0.03). Smoker educators reported less favourable oral self-care habits than non-smokers. Female gender (p = 0.002, OR = 2.7) and familiarity with the oral public health field (p < 0.01, OR = 2.5) were associated with recommended oral self-care criteria.
Conclusion:
Dental educators should have positive attitudes towards and beliefs in effectiveness of preventive dentistry in order to increase public awareness of its importance.

Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
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.
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...
