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 ±â€…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.

Experiencing infertility--social work dilemmas in child adoption procedures.

The research deals with experiencing infertility and its consequences in the adoption of a child and focuses on infertile couples that have wished to adopt a child and joined a program preparing them to be foster parents. The results show that most of the infertile couples experience infertility very much as being different from couples with children as well as having to cope with the feelings of deep emotional loss resulting from the inability to reproduce biologically. There is therefore the question whether these facts should be taken into account by the profession (i.e. social workers) when dealing with child adoption as, according to most of the respondents of our survey, the process of coming to terms with infertility and its consequences is an important factor in establishing healthy family relationships and the child's identity within the adoptive family. We concluded from the results of the research that the infertile couples preparation program for adopting a child carried out by the Society of Adoptive Families "Deteljica", is a comprehensive autopoietic social workers' answer to the needs of participants for a successful adoption of a child, as it makes it possible to supply these future adoptive parents with the requisite information and experience and provides support to the entire family upon accepting a child in its midst, while its fundamental attribute is offering help to couples in overcoming the traumas resulting from their infertility.
