The Head of Oberstown says standards are improving at the detention campus.
Politicians are discussing findings by the health watchdog this afternoon.
In August, a report found that only 2 of 10 standards at the Children Detention Campus in Oberstown were compliant.
It showed young people were isolated for up to nine days with little detail on the reasons why. In one case the boy spent eight days in separation without access to fresh air.
"In October 2017, the board adopted a statement on restrictive practices to underscore the importance of using single separation and other restrictive practices as a measure of last resort", Director of Oberstown, Pat Bergin told the committee.
"The number of physical restraints have substantially decreased in Oberstown because people are spending an awful lot more time talking" he added.
