20.500.12556/RUL-155451 Changes in the swallowing pattern and tongue posture during the transition from deciduous to mixed dentition a longitudinal ultrasonography study Background: Given the importance that swallowing pattern and tongue posture might have in the aetiology of malocclusion, it appears important to be aware of the physiological changes of tongue function and its posture. Objectives: The study aimed to assess changes of the swallowing pattern and tongue posture during the transition from the deciduous to mixed dentition and the association between them. Materials and Methods: The study included 57 subjects aged 5.87 ± 0.5 with normal occlusion, orofacial functions, no history of trauma, or orthodontic treatment. Ultrasonography was used for the assessment of tongue posture and swallowing pattern, where the spontaneous act of swallowing was recorded. To evaluate the possible effect of incisors' eruption, the swallowing pattern and tongue posture ultrasonograms were compared at the deciduous (DD), early mixed (EMD), and intermediate mixed (IMD) timepoints. Results: A significant association between the swallowing pattern and tongue posture at the DD and IMD timepoint was found. Moreover, the visceral swallowing pattern decreases with age (odds ratio [OR] = 0.777), as well as with a prolonged phase IIa (OR = 0.071), while it increases when the tongue is postured on the mouth floor (OR = 5.020). Limitations: The young age of the investigated subjects, direct contact of the probe, and the determination of the rest phase of the tongue were considered limitations. Conclusions: No statistically significant changes in swallowing pattern and tongue posture occurred during the transition period; however, a significant association between the swallowing pattern and tongue posture among subjects with normal occlusion, regardless of the dentition phase was detected. deciduous dentition mixed dentition swallowing pattern tongue posture ultrasonography mlečno zobovje mešano zobovje vzorec požiranja položaj jezika ultrazvok true false true Angleški jezik Slovenski jezik Članek v reviji 2024-04-02 14:25:58 2024-04-02 14:26:03 2024-04-03 03:48:59 0000-00-00 00:00:00 2024 0 0 8 str. iss. 1, art. cjad066 Vol. 46 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 616.31 1460-2210 10.1093/ejo/cjad066 190867203 cjad066.pdf cjad066.pdf 1 D1E6F31DEFF87E6F746244E43FACFCED df9dc27e457195d1a58a1df38b5e424f18ca6407d072e81414ae428496f72982 7b19b558-f0ec-11ee-87d4-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182342 https://academic.oup.com/ejo/article/46/1/cjad066/7450171 0 2eaac8c9-f0ec-11ee-87d4-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182341 Medicinska fakulteta 0 0 0
