Coronal caries experience in dentate Jordanian adults

Objective:
To assess the coronal caries experience and associated risk indicators among a sample of Jordanian adults.
Participants And Methods:
A random sample of 1,096 dentate Jordanian adults in Irbid region were interviewed and clinically examined for coronal caries using the DMFS index. Descriptive summary statistics, bivariate, and regression analyses were employed.
Results:
Findings revealed that the mean numbers of coronal decayed surfaces (DS), missing surfaces because of caries (MS), filled surfaces (FS), decayed and filled surfaces (DFS) and DMFS were 6.3, 20.6, 8.0, 14.3 and 34.9 respectively. All subjects had coronal caries experience and 93% had untreated lesions. Subjects of older age, with less education, urban residence, lower incomes, no dental insurance, a smoking habit and irregular oral hygiene practices had a significantly higher coronal caries experience (p < 0.05). Age, income, education, residence, smoking, brushing and flossing collectively explained 45% of the variance for the mean number of coronal DMFS.
Conclusions:
This study provided useful information on the coronal caries status of Jordanian adults. Modifications of several social factors could potentially reduce coronal DMFS, to improve oral health status and function in adults.

Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
01:21Tooth 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.

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...

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...
