Removable orthodontic appliances are known to be the cause of various complaints related to oral handling of food and beverages, phonation and vocalization. To evaluate the complaint regarding appliance and its effect on taste and flavor perception ,100 volunteers were selected for the study. Two groups (I and II) of 50 children each were divided as study and control groups between the age group of 8- 13 years. Selected volunteers were given taste and flavor stimuli and were asked to score as per their perception in different testing sessions. The overall results revealed that volunteers from both study and control groups, irrespective of the use of removable orthodontic appliances showed marked variation in the estimation of the taste and flavor stimuli in different testing sessions. However, the results obtained were statistically not significant.

ABSTRACT Background The sense of smell is very influential in the taste of foods. If the smell pleases us, we anticipate the taste of the food with a great deal of relish. If our sense of smell is impaired, so is our taste. The effect of appliance on taste perceptions has always had a controversial subject. Materials and methods The present study was designed to analyze the change in taste perception in children using removable orthodontic appliances. All the selected volunteers were given different taste stimuli and were asked to score as per their perception. The verbal score was calculated based on the correct and incorrect taste stimuli given to them. Visual analog scale was used to assess intensity and hedonic (palatability) estimation of the volunteers. Results The volunteers from both study and control groups scored different values for taste stimuli. The majority of stimuli were estimated correctly by both groups. There was no statistically significant difference between the study and control groups. Conclusion In different testing sessions, the scoring of the volunteers was nearly constant, indicating that an appliance does not play a major role in the alteration of taste stimuli. Clinical significance The appliance brings about transient change in taste perception, we should educate the patient before delivering the appliance about the transient change in taste perception and encourage full-time wear of the appliance, including during meals, without fear of affecting taste sensations.

Objective: Peer social functioning difficulties characteristic of ADHD persist into adolescence, but the efficacy of interventions for this age group remains unclear. Method: A systematic search of nonpharmacological interventions for adolescents with ADHD (10–18 years) identified 11 trials addressing social functioning, of which eight were included in meta-analyses. Results: Random effects meta-analyses of four randomized trials found no differences in social functioning between treatment and control groups by parent- ( g = −0.08 [−0.34, 0.19], k = 4, N = 354) or teacher-report ( g = 0.17 [−0.06, 0.40], k = 3, N = 301). Meta-analyses of nonrandomized studies indicated participants’ social functioning improved from baseline to postintervention by parent-report, but not teacher- or self-report. All trials had a high risk of bias. Conclusion: These results highlight the paucity of research in this age group. There is little evidence that current interventions improve peer social functioning. Clearer conceptualizations of developmentally relevant targets for remediation may yield more efficacious social interventions.

Khat (Catha Edulis Forskal) is widely cultivated in Yemen and East of Africa. The habit of chewing tender leaves and twigs of khat is deep-rooted in Yemen. Our study investigates the chronic khat chewing and smoking effect on oral mucosa. The sample (n=79) consists of two main groups, khat chewers (n=54) and control groups (n=25). Khat chewers group is divided into 4 subgroups according to duration of khat chewing and smoking habit. The control group is divided into 2 subgroups according to smoking habit. Whitening with mild corrugation, frictional keratosis and frictional keratosis with mild or sever corrugation were the clinical findings. One hundred percent of clinical findings were present on buccal mucosa of chewing side of both smokers and non-smokers whatever the duration of khat chewing period. On the vestibular and mucobuccal fold mucosa, (100 % and 73.3 %) and (60 % and 43.7 %) of the khat chewers group had clinical findings on chewing side of smokers and non-smokers according to khat chewing duration respectively. There was clinical relationship between these lesions and khat chewing, but not smoking. Khat chewing causes oral white lesions on the chewing side and it is found that smoking, clinically, does not exacerbate such lesions.

Tibial tuberosity advancement is a surgical technique to restore the dynamical stability in the knee by advancing the insertion of the patellar ligament, for which it is necessary to advance the tibial crest, being maintained in the desired position usually by a cage and metallic implants. The purpose of this study was to replace the cage with a polylactic acid biodegradable scaffold designed for each patient by 3D printing, inserting platelet-rich in growth factors (PRGF) to demonstrate its osteoinductive properties. To this end, we used the modified Maquet technique to reduce the amount of metal to a minimum. Fifty-three dogs finished the study. The control and PRGF groups did not present any statistically significant differences in terms of ossification degree (p > 0.001) but they demonstrated satisfactory ossification compared to previous publications, although in the PRGF group three of the scaffolds suffered complete reabsorption. The PRGF and control groups did not show any statistically significant differences in terms of lameness degree (p > 0.001). However, the PRGF group showed at the first control some analgesic and anti-inflammatory properties but they were not enough for reducing the functional recovery time in a significant way. The PRGF group did not show any complications or negative results associated with their use.

The contribution describes the effect of the fixed and removable orthodontic appliances on spectral properties of emotional speech. Spectral changes were analyzed and evaluated by spectrograms and mean Welch’s periodograms. This alternative approach to the standard listening test enables to obtain objective comparison based on statistical analysis by ANOVA and hypothesis tests. Obtained results of analysis performed on short sentences of a female speaker in four emotional states (joyous, sad, angry, and neutral) show that, first of all, the removable orthodontic appliance affects the spectrograms of produced speech.

Abstract: Malocclusion problem is often found in the community. Z spring, one of the springs of the active component of removable orthodontic appliances, is divided into two types, namely Z spring with coil and without coil. Both can move teeth in a labial direction, therefore, they can be used to correct simple cases of malocclusion such as malposition of individual tooth. The addition of coil can increase the resilience and effective length of the spring which further increases the force, hence the malposition of the tooth can be corrected more quickly. This study was aimed to analyze the differences between the effectiveness of Z spring with coil and of Z spring without coil in correction of individual tooth malposition. This was a pre-experimental study with a one-shot case study method. There were two treatment groups, namely Z spring with coil and without coil. Each sample was activated by 1 mm per activation to correct tooth with 5 mm linguoversion in typodonts. After that, the number of activations required and the average value of the measurements of both groups were compared. The independent sample T-Test test on the average value of the displacement distance of each tooth showed that there was a significant difference in effectiveness between the Z spring with coil and the Z spring without coil groups (p=0.000; p<0.05). The Mann Whitney test showed that there was also a significant difference in the value of the number of activations for each Z spring sample between the two groups (p=0.000; p<0.05). In conclusion, Z spring with coil is more effective in correction of malposition of individual tooth than Z spring without coil.Keywords: removable orthodontic appliance; Z spring with coil; Z spring without coil Abstrak: Maloklusi merupakan permasalahan kesehatan gigi dan mulut yang banyak dijumpai dalam masyarakat. Z spring merupakan salah satu pegas dari komponen aktif alat ortodontik lepasan yang terbagi menjadi dua, yakni Z spring dengan coil dan Z spring tanpa coil. Keduanya dapat memindahkan gigi ke arah labial sehingga dapat digunakan untuk mengoreksi kasus maloklusi sederhana seperti malposisi gigi individual. Penambahan coil dapat meningkatkan kelentingan dan panjang efektif spring yang meningkatkan gaya sehingga malposisi gigi dapat terkoreksi lebih cepat. Penelitian ini bertujuan untuk menganalisis perbedaan efektivitas Z spring dengan coil dan tanpa coil dalam mengoreksi malposisi gigi individual. Jenis penelitian ini pre-experimental dengan metode one-shot case study. Terdapat dua kelompok perlakuan, yakni Z spring dengan coil dan tanpa coil. Masing-masing sampel penelitian diaktivasi sebesar 1 mm per aktivasi untuk mengoreksi gigi dengan linguoversi 5 mm pada typodont kemudian dibandingkan jumlah aktivasi yang dibutuhkan dan nilai rerata perpindahan gigi kedua kelompok. Hasil uji independent sample t-test pada nilai rerata jarak perpindahan masing-masing gigi menunjukkan terdapat perbedaan efektivitas yang bermakna antara kelompok Z spring dengan coil dan tanpa coil (p=0,000; p<0,05). Hasil uji Mann Whitney terhadap nilai jumlah aktivasi tiap sampel menunjukkan terdapat perbedaan bermakna pula antara kedua kelompok penelitian (p=0,000; p<0,05). Simpulan penelitian ini ialah Z spring dengan coil lebih efektif dalam mengoreksi malposisi gigi individual dibandingkan Z spring tanpa coil.Kata kunci: alat ortodontik lepasan; Z spring dengan coil; Z spring tanpa coil

Abstract Objective: To assess the prevalence, intensity, and extent of the impacts on daily performances related to wearing different types of orthodontic appliances. Materials and Methods: A total of 1657 students, 15 to 16 years old, were randomly selected from those attending all secondary schools in Bauru, São Paulo, Brazil. Only those wearing orthodontic appliances at the time of the survey were included. Face-to-face structured interviews were done to collect information about impacts on quality of life related to wearing orthodontic appliances, using the Oral Impact on Daily Performances (OIDP). Adolescents were also clinically examined to assess the type of orthodontic appliance they were wearing. Comparisons, by type of orthodontic appliance and covariables, were performed using nonparametric statistical tests. Results: Three hundred fifty-seven adolescents (36.1% boys and 63.9% girls) undergoing orthodontic treatment participated in the study. The prevalence of condition-specific impacts related to wearing orthodontic appliances was 22.7%. Among adolescents with impacts related to wearing orthodontic appliances, 35.8% reported impacts of severe or very severe intensity and 90.1% reported impacts on only one daily performance, commonly eating or speaking. The prevalence, but not the intensity or the extent, of condition-specific impacts differed by type of orthodontic appliance (P = .001). Conclusions: One in four Brazilian adolescents undergoing orthodontic treatment reported side effects, specific impacts on daily living, related to wearing orthodontic appliances. Such impacts were higher among adolescents wearing fixed rather than removable or a combination of fixed and removable orthodontic appliances. This information could help to inform patients about the frequency and intensity of sociodental impacts during the course of their treatment.

Abstract Objective: To determine the immune response related to nickel and nickel-free orthodontic appliances using cellular (total and differential leukocytes) and humoral (IgA) quantification. Materials and Methods: Thirty-five Wister rats were randomly distributed into three groups (A, B, and C). In the A group, the animals were subdivided into three subgroups (A1: control, without brackets; A2: nickel-free brackets; and A3: nickel brackets) with seven animals in each group; the animals were sacrificed after 14 days. Groups B and C received only nickel brackets and were kept for 14 days. After this period, the implants were removed and the rats were sacrificed. In group B, the animals were sacrificed 2 days after the appliance removal (16 days in total); and in group C, the animals were sacrificed 7 days after the brackets removal (21 days in total). Total and differential leukocyte number, IgA quantification and histopathologic analysis were done. Histopathologic analysis of subcutaneous tissue related to the orthodontic brackets was done as well. Results: There were significant differences between the number of leukocytes for the nickel-implanted animals and the nickel-free and control groups after 14 days of implantation (P &lt; .05). However, there was no significant difference among groups A1, A2, and A3 for the differential number of leukocytes and for the IgA quantification, except for the number of monocytes, which was three times higher in the nickel group (A3). The histopathologic findings did not show differences between groups. Conclusions: Nickel did not promote significant adverse biological effects.

Good Retention

The success of removable orthodontic appliance mainly depends upon good retention of the appliance. Adequate retention of a removable orthodontic appliance is achieved by incorporating certain wire components, called clasp, which engages the undercuts on the teeth. Clasps are the retentive components of removable orthodontic appliances. There are various designs of clasps advocated for various clinical situations. This article presents an overview of various clasp designs with advantages and disadvantages of each type and their uses in particular clinical situations.
