Abstract
Esthetics is one of the prosthetic treatment goals. Correct selection of anterior teeth, regarding size and appearance, results in a successful treatment. The goal of the present research was to investigate the relationship between interzygomatic width and maxillary anterior teeth width in order to find a better determinant for artificial anterior teeth selection. In this study, the interzygomatic width and maxillary central incisors width and also the width of six maxillary anterior- teeth, in 71 subjects (29females and 42 males) were measured. The results showed a significant difference in maxillary anterior teeth width, comparing men and women, (P<0.05). These measurement in people under study, are less than Europeans. The interzygomatic width was also more in men than women (PO.05), which is, less than of European race. The ratio between interzygomatic and central maxillary incisor width was 15:1 which is less than 16:1 that is used in clinic. Thus, it is recommended to pay more attention to anterior teeth selection, especially in young patients.

Abstract
Background and Aims: Posterior palatal seal is one of the most important areas to support maxillary complete denture. The aims of this study was to evaluate the dimensional accuracy of both direct and indirect relining methods on the maxillary posterior palatal seal area.
Materials and Methods: A maxillary edentulous model was selected. A 1.5 mm layer of wax was placed on the model to create a space for relining material and impression was done by the silicone material and 20 casts was prepared. By putting the wax on the casts and performed of flasking, 20 dentures were prepared. Direct reline method (as Chair side with GC reline) and indirect method (with Acrosoft-TC and firing with Acropars 100) were evaluated. The relined bases were put on the model and the spaces between them in five points (two points on the ridge , two points in the deepest part of palate and one point in the middle of palate) were calculated by the Stereo microscope and each calculations was repeated 5 times and the mean dimensional changes was measured. To compare the groups, data were analyzed using multivariate analysis.
Results: The gap of P.P.S area was between 740.86 and 2356.49 . Direct method (1011.81±60.56) had a lesser gap in comparison with indirect (2056.8±13.13), and both method showed a significant statistic variance (P<0.0001).
Conclusion: Direct method showed a lesser gap in comparison with indirect method. By direct method adaptation of the denture in the P.P.S area would be better.

Abstract
Background and Aims: Xerostomia is a clinical condition that can affect the quality and quantity of saliva. Saliva is considered an important factor in retention of edentulous patient’s denture wearers. Thus, increasing the prevalence of xerostomia in modern societies is considered a limiting factor in the quality of denture retention. This article reviews the most common techniques of denture manufacturing in edentulous patients with xerostomia and investigates the advantages versus disadvantages of each.
Materials and Methods: In this review, PubMed and google scholar search engines were searched for the following keywords: Flexible Denture, Artificial Saliva Reservoir, Hyposalivation, Hypofunction, and Xerostomia. We evaluated the flexible dentures and dentures with artificial saliva reservoirs in both jaws along with their advantages and disadvantages. 10 articles, specifically discussing complete denture fabrication in patients were selected.
Conclusion: Follow-up results showed that the flexible dentures and split dentures with saliva reservoirs to be effective in improving the quality of life of these patients and therefore can be a considered as a successful treatment option in the prosthetic rehabilitation of these patients.

Abstract
Background and Aims: Due to the very high importance of assessing the clinical performance of students, choosing the best assessment tool and method is one of the most important goals and tasks in medical education. The objective of this study was the development of a checklist for the assessment of dental students’ clinical skills of Tehran University of Medical Sciences, in the clinical complete denture course. The second aim was to determine the validity and reliability of the checklist, and The third aim was the evaluation of raters’ and students’ satisfaction.
Materials and Methods: The checklist was developed in expert panel sessions, and the validity and reliability of the checklist were assessed with CVI (content validity index) test-retest and inter-rater reliability methods, respectively. Students (n=15) were evaluated with a developed checklist. At the end of the session, the satisfaction level of staff and students were assessed. The obtained information was reported descriptively with the expression of mean and standard deviation and in the form of relative and absolute frequencies.
Results: The content validity index (CVI) of the checklist was 0.96. The reliability of the checklist confirmed with a high Intraclass Correlation Coefficient (>0.8) (between 0.82-0.97) (P<0.05). The coefficient of agreement in inter-rater reliability was 0.99 (between 0.991-0.998). Raters’ and students’ satisfaction earned a high percentage of satisfaction.
Conclusion: The designed checklist has the optimal features of a good students’ clinical performance assessment tool; it seems that using this checklist can be an excellent alternative method to a global rating scale to assess the clinical skills of dental students in the complete denture courses.
