candida-associated-denture-stomatitis (CADS) is the most common oral infection, affecting approximately 60% of denture wearers in some populations which have a high recurrence rate in spite of medical treatments . Recently, much attention has been paid to the use of natural antimicrobial compounds. The purpose of this study was to compare the effect of punica granatum linn gel(PGLG) with the use of nystatin on growth of Candida albicans.

We prepared 32 patients with CADS divided into 2 groups of 16 patients. nystatin group and PGLG -treated group. Participant PGLG-treated groups were requested to rinse for two weeks, four times a day, 20 drops for 2-3 minutes each day, and then for 30 minutes to avoid eating and drinking. Amount of inflammation and number of colony-forming units (CFU/ml) for each group was counted and compared. Analysis of covariance considering the size of the primary lesion as co-variate was used (software spss 22).

Both Inflammation and number of  Candida colonies in the nystatin group were less than the PGLG -treated group (p=0.049, p=0.024).

Although Punica granatum linn gel led to a decrease in inflammation and Candida colonies; Nystatin was more effective both in reduction of inflammation and colony counts for the treatment of CADS.

The objective of this study was to compare the Von-Mises-stress (VMS) distribution applied to the edentulous ridges from a Polyamide RPD (PRPD) with those from a Cobalt-Chrome RPD (CCRPD).

A patient with mandibular Kennedy Class I, Mod I was selected. The patientchr(chr('39')39chr('39'))s CBCT was cut off at 1 mm sections from the axial dimension. DICOM files were created. A three-dimensional-bone-model was prepared by segmenting the DICOM files and loading them in MIMICS software and the necessary modifications were applied on them using Geomagic software.The three-dimensional-designs were first developed using Exocad2016 CAD software. An extensive force equivalent to 150N was applied. Abaqus Software was used in order to meshing.  Then the stresses applied on the left and right sides of the edentulous ridges were measured.

In both models, the highest distribution of VMS in the edentulous ridges was observed exactly distal to the abutment teeth adjunct to the distal-extension-areas. In CCRPD, the mean stress on the left-edentulous-ridge was 220kPa and on the right-edentulous-ridge was 100kPa. In PARPD, the mean stress on the left-side-edentulous-ridge was 950kPa and on the right-side-edentulous-ridge was 600kPa. The amount of stresses on the edentulous ridges in the PARPD model (form 280Pa to 950PA) were too much less than those of CCRPD model (from 50kPa to 220kPa).

The polyamide bases can be flexed due to the applied forces and the forces can be distributed in them. So that PRPD can transfer very slight stresses to the underneath surfaces compared to CCRPD.

The main purpose of this study is to identify the social responsibilities of universities in Khuzestan province and analyze their current status in 1398. The current research is a theoretical-applied research in terms of purpose and in terms of data collection, it is a mixed (qualitative and quantitative) asynchronous exploratory type. The qualitative method is based on a phenomenological-interpretive perspective and in the quantitative part is the descriptive-survey method. Using a targeted (chain) approach, 32 academic experts were selected. In the quantitative part, by stratified-random quota method, 280 people were selected from 1038 faculty members based on Cochran's formula. The tool of the qualitative section is a deep semi-structured interview and in the quantitative section is a researcher-made questionnaire on university social responsibilities. The content validity and reliability of the interviews were confirmed by experts and the construct validity and content validity of the questionnaire were also confirmed. Cronbach's alpha coefficient in the University Social Responsibility Questionnaire was 0.92. Findings showed that, 20 central categories of social responsibilities of the university were identified, which were categorized using the logic of the Carol model. Also, one-sample t-test showed that the status of the components of social responsibility of the university in the general scale of the average of 2.92 was higher than the hypothetical average of the study (2.5) and the value of T was calculated to be 15.69 which is in good condition and satisfaction.

Full mouth rehabilitation in patients with ectodermal dysplasia (ED) is challenging to accomplish, especially because the affected individuals are quite young when they are assessed; therefore, esthetics is an imperative concern. This clinical report explains the oral rehabilitation of two sisters diagnosed with ED, which shows the optimistic effects on the physical, emotional, and social life of the patients. Case Report: In this clinical report, two treated sisters had anodontia that made difficulties in their eating and speaking. The two sisters had been treated with fixed partial dentures and implants supported prostheses after extracting nonrestorable deciduous teeth. The present permanent teeth were maintained to preserve the Periodontal ligament (PDL) and increase the patient occlusal awareness.

Elements that are necessary to be focused in designing dental treatments for ED patients include age, existent teeth, oral hygiene, psychosocial environment, Occlusal vertical dimension (OVD), bone volume, skeletal growth and development, orthodontics and/or orthognathic surgery, implants, time required for the procedure, maintenance, and cost of treatment.
