## Brief Summary

1. Prevalence of non-nutritive sucking habits (NNSH) in a group of Egyptian children aged 3-8 years old in Giza Governorate.
2. Assessment of factors associated with NNSH.

## Detailed Description

Several studies have reported on the prevalence of non-nutritive sucking behaviors among infants and young children in different populations. Non-nutritive sucking is regarded as a normal part of development, and early studies of its prevalence generally found that 70-90% of children had some history of a non-nutritive sucking habit. Like these early studies, most recent studies have used retrospective methods to assess the prevalence of non-nutritive sucking habits.

Prolonged duration of non-nutritive sucking behaviors may have consequences in regard to the developing orofacial structures and occlusion. Little is known as to why some children have sucking habits beyond the first 2 to 3 years of life.

Prevalence of NNSH and associated factors in Egyptian children might be different.
