Introduction:
Bad breath is a disease affecting 25% of the world's population. Despite the widespread nature of this problem, people's knowledge about this condition is poor.
Objective:
The purpose of this study was to determine the prevalence of halitosis in a cohort of 62 Senegalese subjects with dental prostheses.
Methods:
Breath analysis was based on measurement of volatile sulfur compounds (VSC) using a halimeter. Halitosis was diagnosed ifVSC level was > or = 125 ppb.
Results:
Mean VSC level was 157.7 +/- 152.6 ppb. The prevalence of halitosis was of 35.4% overall, 72.7% in persons with fixed dentures and of 27.3% in persons with removable prostheses.
Conclusion:
The relatively high prevalence of halitosis observed in this study indicates a need to enhance patient awareness of daily hygiene measures for dental prosthesis.

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