Background:
This study was taken to assess the prevalence of deleterious oral habits among 6-12 year old school going children.
Materials & Methods:
A sample size of 832 children was finalized with simple random sampling technique including 444 males and 388 females. To get the demographic information and presence of harmful oral habits a closed-ended questionnaire was developed. Clinical evaluation was also done using mirror and water tests. Chi-square test was done to compare the prevalence of oral habits among different age groups and gender at p<0.05.
Results:
Bruxism (17.3%) was most commonly seen followed by bottle feeding (10.1%), thumb sucking (8.7%), nail biting (5.8%), tongue thrusting (4.9%) and mouth breathing (4.3%). Prevalence of all deleterious habits were more among female children and it also showed significant differences according to age.
Conclusion:
The data showed high prevalence of these oral habits. This highlighted the need for preventive orthodontic treatment at early age of life so that future occurrence of malocclusion can be avoided.

Development of 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...
Assessment of the Mouth
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...

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...
