Effect of Mathieson Laryngeal Manual Therapy in Patients With Muscle Tension Dysphonia After a Therapeutic Course

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.

The effect of cryotherapy on pain during local and total application

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.

Comparison of electronic systems with sensory analysis for the quality evaluation of parenica cheese

The applicability of electronic systems for the quality evaluation of parenica cheese was investigated in fresh smoked and unsmoked cheeses and after seven days of storage. These data were then compared with sensory evaluation results. Fresh samples had stable colour profiles determined by the electronic eye, while the differences in brown colour intensity were confirmed by sensory evaluation. A significant difference in the aroma profiles of samples was recorded by the electronic nose in samples produced in February, April, December (unsmoked cheese) and September (smoked cheese). Based on sensory analysis results using the Wilcoxon nonparametric test, a significant difference was confirmed in February (smoked cheese) and March (unsmoked cheese), when stored cheese had a stronger aroma than fresh cheese (P &lt; 0.05). The suitability of electronic nose and electronic eye for monitoring of parenica cheese quality was confirmed.

EFFECTS OF RULE CHANGES ON PERFORMANCE EFFICACY: DIFFERENCES BETWEEN WINNERS AND LOSERS TABLE TENNIS PLAYERS

The goal of this study was to analyze the differences in table tennis games between winning and losing players, considering changes of rules. The data taken from four major rule changes in 122 games between 244 players in the period 1996-2015 were analyzed. Performance indicators were 30 technical and tactical activities (type, total number, and stroke outcome) as well as serve and return activities (type, total number, serve outcome, and return outcome). A Mann-Whitney-Wilcoxon nonparametric test (p≤0.05) was done. The results showed that the number of strokes per points considering change of rules varied, while domination of forehand play remained. The existence of statistically significant differences between winners and losers in all the analyzed periods: playing with a 38 mm ball to 21 points in eight activities, playing with a 40 mm ball till 21 points in one activity, playing with a 40 mm ball till 11 points in seven activities, and playing with new racket coverings in 14 activities were noted. The results showed the existence of different playing patterns, styles of play, and performance profiles for winning. Nowadays, players use, to a larger extent, different ways to win, but the effectiveness of the serve and return play gained importance.

Clinical evaluation of the effect of acentric double pedicle graft with and without the use of platelet-rich fibrin (PRF) on root coverage outcomes in class I and II Miller root recessions: A randomized clinical trial

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.

Radiopacity of 28 Composite Resins for Teeth Restorations

ABSTRACT Aim Radiopacity is a fundamental requisite to check marginal adaptation of restorations. Our objective was to assess the radiopacity of 28 brands of light-cured composite resins and compare their radiopacity with that of enamel, dentin, and aluminum of equivalent thickness. Materials and methods Composite resin disks (0.2, 0.5, and 1 mm) were radiographed by the digital method, together with an aluminum penetrometer and a human tooth equivalent tooth section. The degree of radiopacity of each image was quantified using digital image processing. Wilcoxon nonparametric test was used for comparison of the mean thickness of each material. Results All of the materials tested had an equal or greater radiopacity than that of aluminum of equivalent thickness. Similar results for enamel were found with the exception of Durafill, which was less radiopaque than enamel (p < 0.05). All the specimens were more radiopaque than dentin, except for P90 (which was equally radiopaque) and Durafill (which was less radiopaque). The thickness of the specimens may influence the similarity to the enamel's radiopacity. All of the composite resins comply with specification #27 of the American Dental Association. The radiopacity of Amelogen Plus, Aph, Brilhiante, Charisma, Concept Advanced, Evolux X, Exthet X, Inten S, Llis, Master Fill, Natural Look, Opallis, P60, Tetric, Tph, Z100, and Z250 was significantly higher than that of enamel (p < 0.05). Conclusion With these composites, it is possible to observe the boundaries between restoration and tooth structure, thus allowing clinicians to establish the presence of microleakage or restoration gap. Clinical significance Suitable radiopacity is an essential requisite for good-quality esthetic restorative materials. We demonstrate that only some composites have the sufficient radiopacity to observe the boundaries between restoration and tooth structure, which is the main cause of restoration failure.
