Aims And Objectives:
This study was designed to evaluate dental conditions, factors contributing to these conditions, and treatment needs among a population from different places in Chad, as part of a general assessment of their oral health.
Patients And Methods:
A cross-sectional nationwide survey was conducted with 1,011 participants. The survey consisted of a brief health interview (conducted by dental students and public health specialists) followed by a 1-2 minutes oral examination (conducted by dental students and dentists).
Results:
Sixty four per cent of the subjects had experienced dental pain, 66.7% had decayed teeth, and 56.6% had gum diseases. Dental pain was found to be distributed according to age, gender and locations (p<0.001). Only 25% of the participants had ever visited a dentist. Males were show to engage in more tobacco use than females (19.2% vs. 0.3%), while females were more likely to have visited a dentist than males (30.8% vs. 22.8%). Brushing of teeth occurred more often in urban than in rural locations (p<0.001), while date, sugar cane and cola nut intake were statistically significant in the older generation compared to the younger subjects (p<0.001).
Conclusion:
There was a significant need for dental treatment and care in the sample population. In addition, the availability of sugar, combined with poor knowledge, utilisation of preventive and restorative oral health care services have been contributed to have several dental conditions.

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...
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...
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...
