Conclusions
malocclusion, sores
Both at baseline and Two-months (adjusted to the baseline scores), participants in the malocclusion group showed compromised socio-emotional quality of life and reported the poorest total OHRQoL. At the baseline, better socio-emotional and total OHRQoL was reported by the fixed appliance group compared to the Twin-Block group but, after two months both groups gave similar sores. Therefore; patients’ perceptions about their experience with the orthodontic appliance might change. Just after finishing the treatment, patients in all groups had similar functional well-being, while after two months; the best functional well-being was in the Twin-Block group followed by the fixed appliance group, and then the malocclusion group.
