Objectives:
To examine the prevalence of tooth loss in Saudi adolescents, to investigate the reasons behind such loss and to identify any associated social and behavioural factors.
Methods:
A cross-sectional study was carried out in the Eastern Province of Saudi Arabia, from March 2006 through January 2007. A total of 484 subjects, aged 14-19-years of age, were included in the study. The subjects had a clinical examination and completed a self-administered questionnaire regarding their demographic, social, oral and general health attitudes. The prevalence and mean tooth loss were calculated, and a binary regression model was used to construct a risk prediction model.
Results:
A 90% response rate was achieved. The prevalence of tooth loss was 40.9% (n=198). Permanent first molars were the most frequently missing teeth (57.1%). The overall mean tooth loss was 0.83 +/- 1.18. Both the proportion and mean tooth loss were significantly associated with sweet consumption, smoking, tooth brushing, dental flossing, dental visiting pattern and self-rated oral health. In logistic regression analysis, five social and behavioural factors had significant independent effects.
Conclusions:
Several socio-behavioural characteristics have been related to the high prevalence of tooth loss among Saudi adolescents. Tooth loss should be urgently addressed through implementation of community preventive programmes in Saudi Arabia.

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.
