Background: the conflict in opinions about the dental and skeletal changes induced by classII malocclusion activator therapy is still present. The aim of this study was to assess theskeletal and/or dental outcomes of treating moderate-severe skeletal class II division Imalocclusion by the activator.Materials and methods: the sample consisted of pre and post treatment records(cephalometric radiographs) of 11 iraqi adolescent patients (7 females 10-11 years old, and 4males 12-13 years old).Results: the results showed significant skeletal and dental changes that reflected significantimprovements in the cardinal features of class II (overjet, overbite, ANB angle, and loweranterior facial height).Conclusion: correlation of the overjet, overbite, and ANB angle in moderate-severe skeletalclass II I cases by the activator into normal range values may be at the expense of unfavorablelower incisors proclination and ii angle which are very important for stability of treatmentresult. The activator can induce skeletal changes that reflect improvements in the antero-posterior and vertical relationships of class II I malocclusion (downward and forward growthof the mandibule, remodeling of glenoid fossa, in addition to the rotation of maxillary andmandibular bases). Acrylic loading and acrylic trimming done in the activator are responsiblefor the dramatic dental changes that can sometimes contribute to the skeletal improvements(extrusion of lower posterior teeth,relative intrusion of incisors, overjet and overbitecorrection, and changing positions of points A and B)

The concept of environmental debt, which has several dimensions, emerged in the nineties. One of these dimensions is spatial, referring to the debts that southern countries sustain due to the extraction of natural resources and environmental damage inflicted upon northern countries. Another dimension, the temporal dimension, concerns the environmental debts that current generations owe to their predecessors. That means past generations are culpable for overuse of natural resources and mismanagement. The debt issue is complex, despite many mechanisms to resolve it. Most important are the recently introduced environmental bonds, an important step forward in the field of sustainable financing of environmental debts.
