ABSTRACT
AIM: Different experimental approaches have demonstrated that children with sleep breathing disorders (SBD) exhibit neurocognitive and behavioural impairment. The present systematic review and meta-analysis aims to quantify neurocognitive deficit disorders in mouth breathing paediatric patients by summarising relevant case-controls studies. Neurocognitive assessment was undertaken with WISC. METHODS: A search strategy was developed on electronic databases including Medline (Pubmed), Scopus, Scileo; Cochrane library from 2000 to June 2022 for published studies analysing neurocognitive skills in children with SBD compared to healthy control groups. The review was performed according to the PRISMA protocol and articles were selected according to the established inclusion and exclusion criteria. The Weighted Mean Differences (95% Confidence Intervals) were calculated between results obtained in WISC tests in SBD patients and healthy subjects. CONCLUSION: Our results confirmed that SBD affected children performed worse than healthy children in terms of quite all the cognitive domains investigated.
ABSTRACT
OBJECTIVES: to assess the effectiveness of Distal Jet without simultaneous fixed appliance treatment. SUBJECTS AND METHODS: twenty subjects with Class II malocclusion who received the Distal Jet appliance to move maxillary molars distally. Subsequently, the canine and premolar distal movements were achieved by the use of.017 x.025 Ni-Ti sectional wires and memory power chain. RESULTS: revealed that Distal Jet is more effective with less anchorage loss when this appliance is used independent of multibracket appliances. CONCLUSION: this study showed that Distal Jet is an effective and predictable appliance. The distal movements of upper premolars, canines and incisors with sectional wires fabricated from.017 x.025 Ni-Ti were biomechanically very effective, simple in clinical application, and did not require any patient compliance.
