During infancy and preschool age, movement is an integral part of human life. This book
discusses the correlation between cognitive and  motor functioning in preschoolers, as well as
the motor performance differences between boys and girls. Additionally, oral health problems
affect  children's  quality  of  life  by  impairing  their  physical  and  psychological  and  social
functioning  well-being.  The  main  oral  health  related  problem  in  preschool  children  is
associated  with  dental  pain  that  may  affect  sleep,  cause  difficulty  in  eating  and  affect
learning. This book explores how the mouth affects quality of life and the epidemiology of
dental  pain  including  the  determinants  of  oral  diseases.  In  addition,  the  authors  review
strategies  to  promote  oral  health  in  preschool  children.  Other  chapters  show  methods  and
techniques used for evaluation of lung function status in preschool children. Those techniques
are commonly used in preschool age and make possible not only to help in diagnosis, but also
in controlling and monitoring the disease progress or efficacy of the treatment.
