determination of the relative frequency of oral and maxillofacial pathological lesions among the Egyptian children and compare it with the global reports.

Oral and maxillofacial pathology in pediatric patients differs from the general population, as the nature of lesions in children changes with growth and development. Oral and maxillofacial pathology encompasses a wide spectrum of diseases, some of which (i.e. aphthous ulceration, geographic tongue, and herpes labialis) can be diagnosed on clinical presentation alone. For other soft tissue diseases and for pathology with bony components, incisional or excisional biopsy is mandatory to establish a definitive diagnosis .

Several studies illustrated that oral and maxillofacial pathology in pediatric populations varies based on the geographic location of the population as racial and environmental specificities and the lifestyle of each population may influence the prevalence of these diseases .

Although there is increasing literature regarding the incidence and prevalence of pediatric oral and maxillofacial pathology, there is no study investigating the range and frequency in Egyptian children.
