Abstract
Childhood developmental disorders have serious adverse impacts on the
psychological and social well-being of children and their families. Despite the burden
that developmental disorders impose on children and adolescents, most countries do
not provide satisfactory care to those in need. These developmental disorders can either
be present as a single finding or as a part of syndrome. This chapter focuses on the
developmental disorders affecting the teeth, tongue, and lip. The spectrum of these
developmental disorders varies widely. In each case, the anomaly is first described,
followed by diagnostic information, including the availability of various treatment
options. Early diagnosis is often crucial for the effective treatment of functional and
developmental aspects. This will improve the prognosis for better functional and
aesthetic outcome for these patients and lead to a better quality of life, not only for the
patients themselves but also for their families.
