Background. Acentric double pedicle graft is an alternative to double pedicle graft, which can improve clinical outcomes by removing tension in sutures. This study examined the effect of using platelet-rich fibrin (PRF) on the success rate of acentric double pedicle graft in treating patients with Miller Class I and II recessions. Methods. A total of 16 Miller Class I and II lesions were studied in 8 patients. The samples were divided into two groups in terms of PRF use: with PRF and without PRF. Indices, including recession depth, width of keratinized gingiva and pocket depth, were measured with a standard Michigan O probe with Williams marking. Six months later, Kolmogorov-Smirnov test and Wilcoxon nonparametric test were applied with SPSS17 to analyze data. Results. The recession depth, width of keratinized gingiva, and increased root coverage exhibited a significant difference between the two groups after surgery, but no significant difference was found in pocket depths. Conclusion. Applying PRF with acentric double pedicle graft reduced the recession depth, increased the width of keratinized gingiva and enhanced the extent of root coverage when compared with the situation where PRF was not used. Therefore, this study supports the use of PRF with acentric double pedicle graft in root coverage treatments.

Background: analgesic effect of total and local cryotherapy in people older than 55 years, in respondents with various diagnoses, most often with degenerative diseases, especially with gonarthrosis, coxarthrosis, spondylosis, osteoarthritis and polyarthrosis. Objective: the aim of the survey was to process information from the field of total and local cryotherapy and to analyze the information obtained using questionnaires. We process the percentage effect of total and local cryotherapy on the intensity of painful symptoms, feeling, tolerance and satisfaction of respondents after completing ten therapies. Materials and methods: the group of respondents consisted of 35 men and 65 women aged 55 to 81 years. A total of 100 respondents qualified for the survey. 50% of respondents participated in total cryotherapy and 50% of respondents participated in local cryotherapy. Results: we processed the results using MS Excel and IBM SPSS. The Modified Laitinen Pain Questionnaire was used. Due to established hypotheses and the nature of the data, we used the Kolmogorov – Smirnov test, the non-parametric Mann – Whitney U-test and the Wilcoxon nonparametric test. The results show that with the help of local and total cryotherapy, the intensity of painful symptoms is lower. Conclusions: the performed analysis of the data by means of a questionnaire showed that local and total cryotherapy alleviates pain and has an analgesic effect.

The aim of this study is to investigate the nutritional approaches of student athletes studying at the university during the coronavirus outbreak period. Participants consisted of students studying and doing sports at the University. 446 students, 246 males and 200 females, participated in the study. Besides the personal form, students were filled the questionnaire testing questionnaire. Students voluntarily participated. The surveys were done on social media. Nutritional habits questionnaire consists of 12 questions. In the preparation of the survey questions, the questions proved validity of the researches which have been done on the subject before have been used. SPSS 23.00 package program was used in statistical analyses. Kolmogorov-Smirnov test was performed to test whether the data was normally distributed and it was determined that the data showed normal distribution. Independent t-test, paired t-test, unidirectional variance analysis and LSD tests were used in statistical operations. There was no significant difference in students' nutrition approaches by gender, both in the pre-outbreak period and in the outbreak period points (p> 0.05). Nutrition scores were significantly increased during the outbreak period (p <0.001). A significant difference was found between the students who felt bad before the epidemic and those who felt well before the epidemic and their nutritional scores according to the levels they felt (p <0.05). A significant difference was found between the pre-outbreak period and post-epidemic nutrition scores of the sports faculty students (p <0.05). During the coronavirus epidemic, university student athletes have either increased their nutritional opportunities or have changed their eating habits positively to keep their immune systems strong or both. The fact that sports faculty students have better nutrition compared to other faculty students can be attributed to their taking courses in nutrition, health and similar. It is recommended to give lectures or seminars on nutrition to athlete students. Keywords: Student, Nutrition, Sports Nutrition, Nutritional Approach, Covid-19

Objective To determine whether statistical differences occur in total cost, length of stay, ICU days, and surgical complications, depending on the volume of laryngectomy procedures performed. Methods Secondary laryngectomy data from 108 hospitals participating in the University Health System Consortium was examined. All laryngectomy surgical cases occurring from July 1, 2001, through June 30, 2005, with an ICD-9 code of 30.3 or 30.4 were analyzed (N=4,551). The cases were divided into 3 categories based on the number of surgical laryngectomy cases performed by hospital. Those volume categories were high, as defined by organizations with 100–233 cases (n=1712); medium, between 60–99 cases (n=1353); and low, between 4–59 cases (n=1458). 4 dependent variables were examined including total cost, length of stay, ICU days, and complications. Results The 4 dependent variables were analyzed for normality by performing a Kolmogorov-Smirnov test. All 4 variables were non-normally distributed. A Kruskal-Wallis test was then performed on each variable to determine if a statistically significant difference appeared between the 3 volume categories. Each variable was found to have statistical significant differences between the groups, with the high volume hospitals having the lowest cost, shortest length of stay, shortest ICU days, and smallest complication rate. Conclusions This study showed that hospitals with higher surgeon volume for total laryngectomies had reduced total cost, length of stay, number of ICU days, and complication rate for their patients.

Introduction: This study aimed to investigate the effect of Mathieson Laryngeal Manual Therapy (MLMT) following a therapeutic course in patients with primary Muscle Tension Dysphonia (MTD). Materials and Methods: Twelve patients with primary MTD participated in this study. At first, videostroboscopy and perceptual voice assessment was performed, and the Persian version of Vocal Tract Discomfort (VTDp) scale was completed. After two and a half weeks that patients received no treatment, the assessments were repeated to evaluate the effect of spontaneous recovery. For studying the effect of MLMT, it was presented in five sessions. Then, all assessments were repeated. The frequency of supraglottic activity was elicited. For the perceptual evaluation and VTDp, the Wilcoxon nonparametric test was used to study and compare the effect of spontaneous recovery and MLMT. Results: After spontaneous recovery, a significant difference was observed only in strain (P<0.05). After MLMT, the frequency of supraglottic activity decreased, and perceptual voice parameters significantly changed (P<0.05), but the VTDp showed no significant difference (P>0.05). There was no significant difference between spontanous recovery and MLMT based on the paerceptual voice evaluation and VTDp scale (P>0.05). Conclusion: The MLMT can remarkably improve the supraglottic activity and perceptual characteristics of voice in primary MTD after a therapeutic course. Further studies are recommended to confirm the effectiveness of MLMT on decreasing VTD sensations.

ABSTRACT Background The purpose of this clinical trial was to compare the outcome of gingival recession technique using the coronally advanced flap (CAF) with platelet-rich fibrin (PRF) and amniotic membrane. Materials and methods About 15 patients with bilateral Miller class I buccal gingival recessions (4–5 mm) in maxillary and mandibular canines were selected. The recessions were randomly assigned to receive either the CAF with PRF or the CAF with amniotic membrane. Recession height (RH), recession width (RW), width of keratinized tissue (WKT), thickness of keratinized tissue (TKT), probing depth (PD), and clinical attachment level (CAL) were measured at baseline as well as 6 months postsurgery. Patient satisfaction with esthetics, root sensitivity, and postoperative pain was also evaluated. Results The average percentages of root coverage for CAF with PRF and CAF with amniotic membrane were 92.95% and 97.40% (p < 0.05) respectively, and the complete root coverage observed was 56.94% and 76.47% respectively. The CAF with amniotic membrane showed a statistically significant increase in TKT (p < 0.05). There were no significant differences between the two groups with regard to RH, RW, WKT, PD, and CAL. The esthetic condition after both treatments was considered satisfactory by the patients. Conclusion The outcome of this study reflects that CAF with PRF and amniotic membrane can be successfully used to treat class I gingival recession. How to cite this article Gautam A.

Latar Belakang: Upaya peningkatan derajat kesehatan pada sektor lingkungan salah satunya dengan pengadaan sarana lingkungan fisik yang sehat seperti jamban keluarga. Berdasarkan data Laporan Kemajuan Akses Sanitasi Kumulatif Nasional Tahun 2019, penduduk Jawa Timur yang masih menumpang ke jamban sehat sebanyak 879.969 Kepala Keluarga dan yang berperilaku Open Deficiation (OD) sebanyak 969.663 KK.Tujuan: Menganalisis perbedaan faktor enabling terhadap praktik buang air besar antara desa belum ODF dengan desa ODF.Metode: Jenis penelitian observasional analitik kuantitatif dan kualitatif dengan desain penelitian Cross Sectional. Dianalisis secara univariate menggunakan uji One Sample Kolmogorov-Smirnov test dan bivariat menggunakan uji Mann-Whitney U test”. Dari uji ini diperoleh kemungkinan hasil uji yaitu signifikan atau bermakna α = 0,05 maka terdapat perbedaan yang bermakna antara variable yang diuji. Hipotesa diterima apabila p value ≤ 0,05.Hasil: Uji statistik Mann Whitney U test menyatakan adanya perbedaan pada praktik buang air besar antara desa belum ODF (Kelurahan Jagir) dan desa ODF (Kelurahan Ketintang) dimana pada kepemilikan lahan pada Kelurahan Jagir masyarakat tidak memiliki lahan sendiri dan lahan yang ditempati merupakan milik PT. KAI yang berpengaruh pada ketersediaan jamban sehat, sekalipun memiliki jamban tetapi tidak dilengkapi dengan septic tank, sedangkan pada Kelurahan Ketintang rata-rata masyarakat memiliki lahan sendiri, sehingga mempermudah masyarakat memiliki jamban yang dilengkapi dengan septic tank. Hal ini dikarenakan nilai p-value = 0,000 < dari α (0,05), dimana jika p-value < α, maka H0 ditolak dan Ha diterima.Kesimpulan: Lahan yang ditempati  masyarakat Jagir bukan milik sendiri sehingga mempersulit warga untuk membangun jamban sehat, serta jamban yang ada tidak memenuhi persyaratan jamban sehat, sedangkan masyarakat Ketintang yang rata-rata tinggal di dekat sungai tetapi telah menerapkan praktik buang air besar yang benar dengan menggunakan jamban sehat.AbstractBackground: One of the efforts to improve health status in the environmental sector is the provision of a healthy physical environment such as family toilet. Based on data from the 2019 National Cumulative Access to Sanitation Progress Report, the population of East Java who still uses healthy latrines is 879,969 households and those who have Open Deficiation (OD) behavior are 969,663 families. Objective: Intervention of possible factors needs to be done because these factors are supporting/enabling factors, where if we do a certain intervention it will be difficult if the facilities and infrastructure are not available/ not supported. Methods: This type of research is observational analytic quantitative and qualitative whith a cross sectional research design. The data analysis technique was univariate using the One Sample Kolmogorov-Smirnov test and bivariate analysis using the Mann-Whitney U test. From this test, it is obtained that the test results are signicant or significant α = 0.05, so there is a significant difference between the tested variables. The hypothesis is accepted if the p value is ≤ 0.05. Results: The statistical  test of the Mann Whitney U test states that there is a differences in the practice of defecating between Kelurahan Jagir and Kelurahan Ketintang where in land ownership in Kelurahan Jagir, the community does not own their own land and the land occupied is owned by PT.KAI has an effect on the availability of healthy latrines, even though it has a latrine but is not equipped with a septic tank, while in Ketintang Village the average person has their own land, making it easier for the community to have a toilet equipped with a septic tank. Conclusion: The land occupied by the Jagir community is not their own, making it difficult for residents to build healthy latrines, and the existing latrines do not meet the requirements for healthy latrines, while the Ketintang community who mostly live near the river but have implemented the correct practice of defecating using healthy latrines.

The basic motivation and primary goal of this paper is a qualitative evaluation of the performance of a new weighted statistic for a nonparametric test for stochastic dominance based on two samples, which was introduced in Ledwina and Wyłupek [TEST 21 (2012) 730–756]. For this purpose, we elaborate a useful variant of Kallenberg’s notion of intermediate efficiency. This variant is general enough to be applicable to other nonparametric problems. We provide a formal definition of the proposed variant of intermediate efficiency, describe the technical tools used in its calculation, and provide proofs of related asymptotic results. Next, we apply this approach to calculating the intermediate efficiency of the new test with respect to the classical one-sided Kolmogorov–Smirnov test, which is a recognized standard for this problem. It turns out that for a very large class of convergent alternatives the new test is more efficient than the classical one. We also report the results of an extensive simulation study on the powers of the tests considered, which shows that the new variant of intermediate efficiency reflects the exact behavior of the power well.

Abstract Objective SARS-CoV-2 can be carried by aerosols and droplets produced during dental procedures, particularly by the use of high-speed handpieces, air-water syringes, and ultrasonic scalers. High-volume evacuators (HVEs) and extraoral vacuum aspirators (EOVAs) reduce such particles. However, there is limited data on their efficacy. This study aimed to determine the efficacy of HVE and EOVA in reducing aerosols and droplets during ultrasonic scaling procedures. Materials and Methods Three ultrasonic scaling simulations were conducted on mannequins: 1. saliva ejector (SE) was used alone (control); 2. SE was used in combination with HVE; and 3. SE was used in combination with HVE and EOVA. Paper filters were placed on the operator's and assistant's face shields and bodies, and the contamination of aerosols and droplets was measured by counting blue spots on the paper filters. Statistical Analysis All data were analyzed for normality using the Kolmogorov–Smirnov test. The differences between each method were analyzed using a two-way ANOVA, followed by a posthoc test. The differences were considered statistically significant when p < 0.05 Result Using HVE and EOVA reduced aerosols and droplets better than using SE alone or SE and HVE: the posthoc test for contamination revealed a significant difference (p < 0.01). The assistant was subjected to greater contamination than the operator during all three ultrasonic scaling procedures. Conclusion The usage of HVE and EOVA significantly reduced aerosols and droplets compared with using SE solely. Using these techniques together could prevent the transmission of airborne disease during dental cleanings, especially COVID-19. Further studies of aerosol-reducing devices are still needed to ensure the safety of dental workers and patients.
