A survey was administered to 168 parents and their children at the end of mixed dentition treatment for Class II correction utilizing bionators and headgears to investigate attitudes of parents and patients toward bionators and headgears and to elicit factors associated with compliance. Directional differences between parent and child responses occurred frequently with agreement ranging from 41 to 100%, averaging 69% overall. The results indicate that the orthodontic patient population has medical and dental health as a priority. While parental and child reasons for seeking treatment may be different, it appears that both groups seek care for perceived benefits of health, decreased present and future oral problems, peer influences, and dental self image improvement. Additionally, children who are undergoing treatment perceive that others do not understand what they are going through, they may be embarrassed, and some may break their appliances to annoy the parent or orthodontist. Pain, decreased ability to speak, and difficulty chewing were reported to decrease appliance wear. Patient understanding of the treatment goals was reported to increase compliance. The bionator caused more instances of speech problems and associated non‐compliance than the headgear. The headgear caused more instances of pain, but did not cause significantly less associated compliance than the bionator. The results suggest that bolstering the patient‐orthodontist relationship, informing the patient about the treatment goals, methods, and their individual role, and offering immediate short term rewards can potentially increase patient compliance.
Objective: To determine whether swept-source optical coherence tomographic angiography (SS-OCTA) can demonstrate choroidal perfusion abnormalities seen on fluorescein angiography (FA) in giant cell arteritis (GCA).
Design: Observational case series.
Participants: Six eyes of 3 patients with bilateral ischemic optic neuropathy secondary to GCA, and one control patient without ocular involvement from biopsy-confirmed GCA.
Methods: En face SS-OCTA (DRI OCT Triton, Topcon, Tokyo, Japan) and FA centered on the macula were obtained at presentation. SS-OCTA was segmented into superficial and deep retinal capillary plexuses and the choriocapillaris laminae. SS-OCTA images were independently analyzed for perfusion abnormalities and compared with corresponding FA images.
Main Outcome Measures: Correspondence of choroidal angiographic abnormalities on SS-OCTA and FA.
Results: SS-OCTA showed decreased angiographic signal within the choriocapillaris in 5/6 eyes and corresponded to hypoperfusion abnormalities on FA in similar geographic distributions in 5/5 eyes. SS-OCTA also showed dilation of the deep retinal capillary plexus overlying the area of choroidal hypoperfusion in one eye. In the one eye without angiographic signal abnormalities on SS-OCTA, no perfusion changes were noted on FA. One control patient without ocular involvement from biopsy-confirmed GCA did not show choroidal perfusion changes on SS-OCTA or FA.
Conclusions: This case series demonstrates comparability between SS-OCTA and FA in detection and characterization of choroidal hypoperfusion secondary to GCA. As a rapid and non-invasive tool, SS-OCTA may serve as a viable alternative to FA in the diagnostic evaluation of GCA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
