This legislation changed the way that mental health services were handled and also led to the closure of many large asylums. Many laws soon followed assisting more and more people with EBDs. 1978 came with the passing of Public Law 94- 142 which required free and public education to all disabled children including those with EBDs. An extension of PL 94–142, PL 99-457, was put into act which would provide services to all disabled children from the ages of 3-5 by the 1990–91 school year. PL 94-142 has since been renamed to the Individuals with Disabilities Education Act (IDEA). Use and development of the term
Various terms have been used to describe irregular emotional and behavioral disorders. Many of the terms such as mental illness and psychopathology were used to describe adults with such conditions. Mental illness was a label for most people with any type of disorder and it was common for people with emotional and behavioral disorders to be labeled with a mental illness. However, those terms were avoided when describing children as it seemed too stigmatizing. In the late 1900s the term "behaviorally disordered" appeared. Some professionals in the field of special education accepted the term while others felt it ignored emotional issues. In order to make a more uniformed terminology, the National Mental Health and Special Education Coalition, which consists of over thirty professional and advocacy groups, coined the term "emotional and behavioral disorders" in 1988.
Brachygnathism, or colloquially parrot mouth, is the uneven alignment of the upper and lower teeth in animals. In serious cases, the upper teeth protrude beyond the lower teeth. Problem with parrot mouth occur if the molars at the back of the mouth are also uneven, resulting in large hooks forming on the upper molars and the rear of the lower back molars. Horses with parrot mouth often require dental treatment at least every six months to remove the hooks and maintain alignment.The equivalent conditions in humans are termed retrognathism or prognathism depending on whether the lower jaw is too far back or too far forward respectively.
