“…However, the children groups (3–17 years) did not show any such differences in the number of chewing cycles and/or chewing sequence duration between different food hardness. It has been suggested that a lesser number of chewing cycles or shorter chewing sequence duration may not be good indicators of chewing performance [ 34 ]. A good masticatory performance could be assessed as the “right” texture of the boli and the right time where the food has been adequately pulverized, and an “ideal” agglomeration of the bolus is achieved.…”

Objective To investigate the effects of food hardness on chewing behavior in children compared with adults. Materials and methods Healthy children (3-17 years) were equally divided into five groups based on their dental eruption stages. Each participant ate soft and hard viscoelastic test food models (3 each), while the three-dimensional jaw movements and electromyographic (EMG) activity of the bilateral masseter muscles were recorded. The data from the children were compared with a control group of healthy adults (18-35 years). The data were analyzed with nonparametric tests. Results There was no significant difference in the number of chewing cycles and the duration of the chewing sequence between children groups and adults. Children with primary dentition (3-5 years) showed shorter lateral jaw movement and higher muscle activity at the end of the chewing sequence, compared with adults. Further, children's age-groups (3-14 years) failed to adapt their jaw muscle activity to food hardness. However, at the late-permanent dentition stage (15-17 years), children were capable of performing adult-like chewing behavior. Conclusions Overall, it seems that children as young as 3-year-old are quite competent in performing basic chewing function similar to adults. Yet, there are differences in the anticipation or adaption of jaw muscle activity and jaw kinematics to food hardness. Clinical relevance The study may have clinical implication in the diagnosis and management of children with chewing impairment associated with dental malocclusions and other orofacial dysfunctions.

“…The purpose of the “tick test” is two- fold: first to show the patient that as the treatment progresses, the muscles start to relax and the number of ticks reduces, the second is to show the patient that tooth contact is not necessary for normal function. Tooth contact investigation has historically been a controversial subject, but modern technology will be able to demonstrate that tooth contact does not occur in normal function [ 22 - 24 ]. Once these two messages are embedded in the subconscious, together with the fact that the patient is starting to look better, it seems that a trigger is formed which will help to stop the patient bruxing in both day and night time.…”

Background:Occlusal appliances of various designs have been described in the literature. They usually have to be worn for substantial periods including night time to have the desired effect for which they are designed. The Oralift® appliance has been designed to address the signs of facial ageing and to help stop parafunctional habits. The appliance is based on the principles of the pivot appliance and is worn for very short periods, never at night and not even every day. The maximum usage recommended is two hours every third day.Objective:This is a review of five patients who have been treated with Oralift® with the aim of assessing whether the visual changes seen by wearing the appliance can be quantified by changes in volume as measured by 3D Imaging, and if this quantification could be useful in improving the outcomes for each patient.Methods:The patients were fitted with the appliances in general practice, and 2D images were taken before, during and after treatment. Afterwards, the patient attended King’s College London, to have 3D imaging.Results:3D imaging has been proved far superior to standardized 2D photography in assessing the changes taking place on the face, and helped quantify the volume changes.Conclusion:To further improve the outcome for each patient, the 3D imaging should be done before the visit to the practitioner or ideally by the practitioner so that the results could be assessed, and the treatment adjusted accordingly. The implication of the volume changes requires a much larger study.

“…In the literature view, the following methods are commonly used in the studies investigating the chewing function (2): a-Analysis of chewing movements, b-Analysis of chewing muscle activity (Electromyography studies) (3)(4)(5)(6) or c-Analysis of chewing process results (analysis of the status just after chewing and before swallowing a food particle) (1,7). Efficiency of restorations, the status before orthodontic studies, chewing analyses during and after the treatment process may provide important information about treatment process and outcomes (8).…”

Anah tarKe li me lerÇiğneme, ortodonti, oklüzyon KeywordsMasticatory movements, orthodontic treatment, dental occlusion Amaç: Normal oklüzyonlu ve tedavi altındaki ortodontik anomalili bireylerin çiğneme hareketlerinin karşılaştırılması. Gereç ve Yöntemler: Bu çalışma, maloklüzyonlu 43 hasta ve ortalama yaşları 16,79 yıl olmak üzere, büyüme ve gelişmesi kısmen tamamlanmış, 20'si normal oklüzyonlu ve yaş ortalaması 24,77 yıl olan toplam 63 birey üzerinde yapılan prospektif bir klinik çalışmadır. Bulgular: Oklüzyon süresinde (p<0,05) ve açılma ve kapanma oranlarında anlamlı fark bulundu (p<0,01). Ayrıca, sınıf 1 (p<0,05) ve sınıf 2 (p<0,01) malokluzyonların modifikasyon sonuçlarında da anlamlı farklılıklar bulunmuştur. Sonuç: Ortodontik tedavinin başlangıcında elde edilen çiğneme hareketlerinde dişlerin yeniden konumlandırılması, maloklüzyonlu bireylerde tedavinin başlangıcından itibaren altı aylık sürenin sonunda değişme eğilimindedir. ÖzObjective: Comparison of chewing movements of individuals with normal occlusion and those with orthodontic anomalies under treatment. MaterialsandMethods:This is a prospective clinical study carried out on a total of 63 individuals, including 43 patients with malocclusion and an average age of 16.79 years, whose growth and development were partially complete and 20 individuals with normal occlusion and an average age of 24.77 years. Subjects with normal occlusion have not any orthodontic treatment history. Results: There were significant differences in chewing occlusion times (p<0.05) and opening and closing times (p<0.01). Furthermore, significant differences were also found in modification results of class 1 (p<0.05) and class 2 (p<0.01) malocclusions. Conclusion: Repositioning of the teeth in chewing movements obtained at the onset of orthodontic treatments tends to change within the end of the 6-month period from the onset of the treatment in individuals with malocclusion.
