ABSTRACT Background Impression techniques have evolved considerably during the last decade. However, it needs to be assessed whether the retention achieved with these techniques is adequate enough to establish them as an alternative to the conventional techniques. Purpose This study was planned to evaluate the retention of denture bases fabricated using the selective pressure, functional and Massad's impression techniques. Materials and methods Twenty completely edentulous patients were selected and each of them was subjected to three definitive impression techniques: selective pressure, functional and Massad's techniques. The permanent bases were fabricated and checked for retention with a custom made retention checking apparatus. The load required to dislodge the denture base fabricated using each technique, from the maxillary foundation was recorded and this data was subjected to statistical analysis. Results The statistical analysis shows that the difference between the selective pressure and the functional impression technique is statistically significant (p = 0.046) However, this result needs verification by collecting more data or designing another study, since the observed p-value is closer to the significance level (i.e. 0.05). Though the difference between the means of Massad's and functional techniques is of 39 gm, it is statistically not significant (p = 0.09). The difference between means load to dislodge denture bases for selective pressure and Massad's techniques (5.5 gm) is not statistically significant (p = 0.95). Conclusion The three impression techniques yielded adequately retentive permanent denture bases. However, retention of the denture bases obtained from the selective pressure impression technique was best, followed by the Massad's and functional techniques. Clinical implication The results of this study indicated that the denture bases fabricated using selective pressure impression technique were more retentive than the Massad's and the Functional impression technique.

In this study we have aimed to present statistical evaluation of changes in the surface roughness of the solid tone areas on CtP flexo printing plate in dependence of print run. Changes in flexo plate surface roughness is influenced by the plate-making process, printing pressure and speed, the interaction with the ink and printing substrate and by the wear of the printing plate due to long print-runs. Thus, the aim of this research was to evaluate the changes in the amplitude surface roughness parameters (Ra, Rp, Rv and Rz), between the printing plates used for different print runs. In the experiment, we have employed three sets of CtP flexo printing plates, for three colors-cyan, magenta and blue. The first set was not used for printing, the second was used to print 7 rolls of substrate and the third is used to print 11 rolls of printing substrate. The amplitude surface roughness parameters were compared by applying independentsamples t-test method using the software SPSS (Statistical Package for Social Science) with a 0.05 significance level. Statistical analysis revealed that the difference between the amplitude surface roughness parameters measured on CtP flexo printing plates are significant with a 95% confidence level, whereas the statistical significance pointed out that with the longer print runs, the difference will be strongly expressed.

This study aimed to measure the implementation of the practice in the women’s clothing course in terms of the skill variable making construction/flat clothing patterns, applying the grading pattern and making women’s clothing. This study used a quantitative approach. The research subjects were all students who programmed the women’s clothing course. 43 students of the UNESA Fashion Design Education undergraduate study program. Data analysis used 2x4 factorial ANOVA followed by a comparison of the mean using SPSS software. The honest real difference test (Tukey test) was used to test the difference between the two data at the 5% significance level. Observations were made on two things, namely the length of time for making patterns and clothes, on industrial and custom-made clothing. Industrial clothing consists of one-pieces, blouses/tunics, skirts, and pants, while costume-made clothing consists of deuce pieces, long dresses, short dresses, and modern kebaya. The method of making patterns reads into two ways, namely flat and grading. The results showed that the grading method can speed up the time for making industrial and custom-made clothing patterns. The manufacture of one-piece industry clothing takes longer than others. Meanwhile, the long costume-made dress takes longer than the others

Maintaining acrylic denture hygiene is a necessary to prohibit the growth of several oral fungi such as Candida albicans. Candida albicans are the main etiological microorganism of denture stomatitis. One of the ways to clean denture is by immersion on synthetic denture cleaner liquid such as oxygenizing denture cleaners. However, synthetic denture cleaner have several limitation due to its biocompatibility on human body especially oral tissue. Chitosan is a derivate of chitin, a natural compound of sea creature exosceleton. Chitosan have antifungi and antibacterial nature. The objective of this study is to evaluate the antifungi efectifity of chitosan 2% on acrylic heatcured and compare it with oxygenizing denture cleaner. Aquades is used as a control. The sample consists of 15 acrylic heatcured bars (10x10x2 mm) prepared by contamination on Candida albicans suspensions at temperature 37°C for 24 hours and immersed on 3 different treatments wich are chitosan 2%, oxygenizing denture cleanser, and aquades as control and then, the solutions are being vibrate and put into sabouraud dextrose agar medium. The colony of Candida albicans counted manually. Result shows, highest mean of Candida albicans colony on aquades group (365,66 CFU/plate), followed by oxygenizing denture cleanser treatment (178,33 CFU/plate). The smallest number colony of Candida albicans are found at chitosan 2% treatment (45,33 CFU/plate). Statistical analysis using ANOVA one way shows F=9.826 and p=0, this means, there is minimal one pair of groups with very significant differential (p<0,01) which are chitosan 2% and oxygenizing denture cleanser compared to aquades as control. The difference between those two treatments also significant. Conclusions of this study is that chitosan 2% solution have a sifnificant effect on prohibiting the growth of Candida albicans colony on acrylic heatcured denture base materials. The effectivity of this solution is significantly higher than oxygenizing denture cleanser treatment.

Background: Early breast cancer patients admitted in the surgical oncology department of Savera Cancer and Multispeciality Hospital. Patients were divided in two treatment arms; Arm A and Arm B. Arm A patient went through MRM and Arm B patients went through BCS. This study included prospective cases of 1 year from June 2019 to June 2020. Method: In all MRM group patients all breast tissue, skin, nipple areola complex and level 1, 2, 3 lymph nodes removed. In all BCS group patients lump was removed with an envelope of normal appearing breast tissue. In all resected specimens free surgical margin was ensured via histopathology reports (HPR). Patients were reviewed in early post operative period for complications and follow up done at the end of 1st, 3rd, 6th and 12th month for recurrence. In treatment Arm A (MRM) 08 patients developed arm ede Result: ma; 05 patients developed shoulder dysfunction; 07 patients developed ap necrosis; 07 patients developed arm dysesthesia. Whether in treatment ARM B (BCT) 04 patient had Seroma formation; 13 patients developed wound infection & wound contracture. Complications were reported in 35% of MRM group (35 out of 100 cases), while they were absent in 65% (65 out of 100). However, in the BCS group, complications were reported in 6.66% cases only (15 out of 100 cases), while were absent in 93.33% (75 out of 100). P value by statistical analysis being 0.283, the difference being statistically insignicant. Recurrence were present in 6.66% of MRM group (8/100) while they were absent in 92.34 % (92/100). However in BCS group recurrences were present in 3.33 % (3/100) and were absent in 97.67% (97/100). P value by statistical analysis being 1, the difference being statistically insignicant. Grading of complications has been captured from CTCAE Version 5.0 (Common Terminology Criteria for Adverse Events). Conclusion: There is slight signicant difference in the recurrence rate, whether the patient had undergone BCS or MRM based on our short term follow-up. However a long term follow-up is required.

EEG happens to be an important tool for brain study providing a non- invasive and cost effective method to detect the effects of alcohol on the human brain. This paper highlights the importance of statistical analysis to determine the usefulness of spectral entropy features for discriminating alcoholics from healthy subjects. The open source EEG database consisting of 10 alcoholic and 10 control subjects recordings under visual stimulus is considered for the study. The EEG signal is preprocessed to remove eye blink artefact using independent component analysis (ICA) and the gamma sub band is extracted by using an elliptic band pass filter to obtain the visually evoked pattern (VEP) signal. The spectral entropy (SEN) coefficients are computed on all the 61 VEP signals of each subject. To obtain a statistical measure of SEN coefficients suitability for classifying the alcoholic EEG, ANOVA tests are performed. Results show that the test exhibits interesting observations in the form of p-value <0.05 (accepted significance level) for most of the channels and p-value >0.05 for the remaining channels. This study may help in identifying those significant channels (p<0.05) which contribute to the classification of both the groups.

ABSTRACT Purpose Simulation of jaw movements in an articulator requires one of the important condylar parameters, i.e. horizontal condylar inclination (HCI) to be registered in the patient and transferred to a mechanical device (articulator). The most popular and commonly used technique to determine horizontal condylar inclination (HCI) is by use of interocclusal records. Clinical studies comparing the effects of different interocclusal recording materials on reproducibility of protrusive settings in semiadjustable articulators have not been studied much. Hence, the present clinical study was conducted to comparatively assess the effects of three commonly used interocclusal recording materials; namely wax, polyvinylsiloxane, polyether in obtaining HCI values in two commonly used semiadjustable articulators; namely Hanau Wide-Vue (arcon) and Dentatus ARH type (non-arcon). Materials and methods One healthy female patient with intact dentition and no signs and symptoms of TMJ problems was selected for the study. With the help of a custom-made protrusive guide, 10 individual protrusive records for each of the interocclusal recording materials were made. These records were used for programming the two articulators and the respective HCI values were noted. The results obtained were tabulated and subjected to statistical analysis. Results The HCI values obtained using each of the interocclusal recording materials in both the semiadjustable articulators was found to be statistically significant. Among the materials polyether gave the highest values with less variability and wax gave low values with greater variation. Conclusion The results of this study indicate that HCI values vary both according to the type of interocclusal recording material employed and the articulator selected.

BACKGROUND: Fournier gangrene (FG) is an urological emergency in the form of progressive necrotizing fascitis caused by polymicrobial infection which affects the perineum and external genitalia. FG that is not diagnosed and treated properly will result in severe morbidity and even mortality for the patient. The assessment of FG becomes clearer with the creation of a scoring system that predicts patient prognostic and therapeutic outcomes, known as the Fournier ganggreen severity index (FGSI). This FGSI includes clinical and laboratory examinations, namely, temperature, pulse, respiratory rate, levels of sodium, potassium, leukocytes, hematocrit, and blood serum bicarbonate. AIM: We aimed to present descriptive retrospective study, which examined the relationship between age and DM with FGSI in FG patients at the Regional General Hospital. METHODS: Data were taken from January 2017 to December 2020 at the Urology Department, dr. Moewardi Hospital Surakarta. There were 32 cases of FG patients, consisting of 20 patients with diabetes mellitus (DM) and 12 non-DM patients. RESULTS: This study found that FG patients with an FGSI score <9 were 24 patients (75%), FG patients with an FGSI score of >9 were 8 patients (25%). Judging by the distribution of the FGSI score according to the age of the FG patient using the chi-square technique, the value p = 0.045. The p-value <0.05 means that at the 5% significance level the difference in the proportion of FGSI scores between age categories of FG patients is significant. The distribution of the FGSI score according to the DM comorbid showed that there were nine patients with an FGSI score of >9 (45.5%) with comorbid DM and no patients without the DM comorbid. Result of statistical test using the Chi-square technique was p = 0.036. The p-value < 0.05 means that at the 5% significance level the difference in the proportion of FGSI scores between patients with and without comorbid DM is significant. CONCLUSION: Judging by the distribution of the FGSI score, it can be concluded that there is significant relationship between the age of the FG patient and the FGSI score and there is a significant relationship between the DM comorbid and the FGSI score in FG patients at dr. Moewardi Hospital Surakarta in the period January 2017 to December 2020.

Covid19 may cause experiences of psychological disorders such as anxiety and depression, stress in families and children. The psychological impact of the coronavirus in all patients should be considered in addition to physical symptoms. Method: In the training intervention group, 4*45 min sessions per week, was conducted by telephone and online. Items such as how the disease occurs, the factors that cause its symptoms and complications, treatment of the disease, the need for treatment of the disease, lifestyle changes, the need for preventive activities such as masking, use of alcohol spray, quarantine, avoid touching contaminated surfaces and avoid losing with friends and relatives and follow proper nutrition tips, advise to calm and stress caused by corona, should be receptive and listened and managed. Support the child. Provide a suitable environment during quarantine. Ask for help from support centers if needed. Have a flexible but regular daily schedule to teach your child to keep a safe distance. Have family coordination at home. Results: According to the obtained results, we found that the distribution of Beck anxiety scores in the pre-examination, post- examination and follow-up stages is normal and the p- value is greater than 0.05 (p 0.00.05). It can be concluded that corona education to parents has been significantly effective in reducing their mean anxiety. scores in the post-examination stage is greater than the significance level (p 0.0 0.05). Therefore, it can be concluded that the difference between the mean adjustment scores at different times is different according to the studied variables. Conclusion: The results of the present research demonstrated that after training anxiety and adjustment in the two groups, information support of patients' families will help them to better adapt in the face of stressful situations. Thus, educating the patients and their family increases the level of information and reduces the anxiety of the patient and the family and reduces the problems facing of the disease. Although families experience high stressors from the corona, but providing the necessary training for parents and increase supports may be necessary to be successful.
