Materials and Methods: A four groups of 10 disc-shaped specimens (10 mm × 1.2 mm) were made from the following CAD/CAM Zirconia blocks: first-generation Zirconia (Ceramill Zi LT) as a control, and three brands of third-generation Zirconia (Ceramill Zolid FX UT, Katana UTML, and Cercon XT) as the experimental groups. Ten discs from each group were subjected to the color measurement using a Spectrophotometer (Hunterlab, EasyMatch QC. Ver 4.90). Then, same discs were subjected to AAA for 3500 cycles. The data were analyzed with the one-way analysis of variance (ANOVA) and Tukey's post hoc test. Data analyses were evaluated at a statistically significance level of P < 0.05. Results: Statistically significant differences were detected in the L*, a*, and b* values among the four groups both before and after AAA. One-way ANOVA was used, which showed statistically significant differences among the groups (P < 0.001). The Ceramill ZI LT showed the greatest change in color (ΔE = 2.74 ± 0.23), followed by Katana UTML (ΔE = 1.91 ± 0.23), Ceramill Zolid FX UT (ΔE = 1.52 ± 0.43), and least change in color was seen in Cercon XT (ΔE = 1.44 ± 0.25). Tukey's post hoc test showed a statistically significantly difference among the test materials, except between Ceramill Zolid Fx UT and Cercon XT, where there was no significant difference seen in ΔE. Conclusion: The AAA protocols used in this study resulted in a significant effect in the (ΔE) of the four-tested Zirconia materials. The Ceramill ZI LT (First Generation) showed the greatest change in color and the least change in color was observed with Cercon XT (third generation).

Objective: The objective of this study was to assess the impact of dental esthetics on the psychological well-being of adult patients attending a university hospital in Saudi Arabia. Materials and Methods: A total of 613 patients attending university hospitals participated in this study by answering the online and printed version of the questionnaires. A Psychosocial Impact of dental aesthetics questionnaire was used in self-assessment for satisfaction with dental esthetics, and a self-perceived dental treatment needs. Collected data were analyzed using descriptive statistics and Chi-square tests. Results: The participants reported smile satisfaction with satisfied (52.4%) and highly satisfied (22.8%), while only 24.8% reported dissatisfaction. Tooth color was the most common cause of dissatisfaction (49.3%). Conclusions: The majority of the participants were satisfied with their smiles, however, a large percentage are still in need of further esthetic dental treatments as their smiles have a major impact on their social and psychological well-being. Hence, more public awareness programs should be directed to educate our community to make better choices of cosmetic dental procedures.","PeriodicalId":32335,"journal":{"name":"Saudi Journal of Oral Sciences","volume":"17 1","pages":"189 - 193"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84986805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study has been carried out with an aim of assessing 3rd year dental student's perception of PBL as a teaching and learning method over a 5-year period based on problem-solving and self-directed learning, cooperative learning, role of facilitator and product discussion. Methodology: The perception of 3rd year students from year 2014 to 2018 was assessed at the end of PBL sessions using a self-administered, structured questionnaire. Their responses were recorded using a five point Likert scale and data collected retrospectively was analyzed. Students' open feedback regarding the PBL process was also recorded and analyzed. Results: A total of 376 participants responded to the questionnaire (female = 250 [65%], male = 126 [35%]). Majority of students agreed that PBL improved problem-solving skill, self-directed learning and perceived that it had a positive impact on cooperative learning. Students also felt that PBL product discussion prepared them for future presentation and helped to clarify concepts. Conclusion: The results suggested that students had a positive attitude toward PBL and it improved their problem-solving skills as well as motivated them to learn and participate actively. Some students felt that PBL was time consuming, yet it was a fun and interesting way to learn.","PeriodicalId":32335,"journal":{"name":"Saudi Journal of Oral Sciences","volume":"37 1","pages":"194 - 198"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89501820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this case report is to add regenerative endodontic cases to the existing literature about the use of plateletrich fibrin (PRF). Three clinically and radiographically diagnosed necrotic immature permanent teeth were treated using PRF as a scaffold for revascularization. The therapeutic protocol involved accessing the pulp chamber, irrigating copiously with sodium hypochlorite, applying a triple antibiotic paste as intracanal dressing, and then provisionally sealing it. After 3–4 weeks, the canal was cleaned and PRF was introduced in the canal that would serve as a scaffold for pulp revascularization. Mineral trioxide aggregate was used to seal the chamber and finally restored with composite. All the cases treated with PRF as a scaffold showed magnificant healing and apical end closure along with thickening of dentinal walls. On the basis of the results obtained in our case reports, we conclude that the revitalization of necrotic infected immature tooth is possible under conditions of total canal disinfection, and PRF is nearly an ideal biomaterial for pulp–dentin complex regeneration.","PeriodicalId":32335,"journal":{"name":"Saudi Journal of Oral Sciences","volume":"21 1","pages":"210 - 215"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77703033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study purpose was to investigate the released levels of fibroblast growth factor-2 (FGF-2) in standard PRF (S-PRF) and low-speed centrifugation concept known as advanced PRF (A-PRF and A-PRF+). Measurements were done at five times interval over 42 days. The aim was to assess the FGF release and the relation between initial platelet counts and the concentrations of FGF-2 release using the following technique: (1) S-PRF, (2) A-PRF, and (3) A-PRF+. Materials and Methods: Twenty-four blood samples were taken from eight random Saudi Arabian national healthy subjects enrolled in the investigation. Blood samples were processed using S-PRF, A-PRF, and A-PRF+ centrifugation protocols. Protein quantification was performed using enzyme-linked immunosorbent assay at 1, 7, 14, 28, and 42-day intervals. Results and Discussion: A statistically significant difference in the mean of FGF-2 measurement between protocols at the 7th day where both S-PRF and A-PRF were significantly higher than A-PRF+ (P < 0.012). Initial platelets' significant count for S-PRF, A-PRF, and A-PRF+ was on day 1, day 7, and 7th day, respectively. Both protocols S-PRF and A-PRF yielded significantly higher release of the FGF-2 when compared to A-PRF+ in Saudi healthy subjects.","PeriodicalId":32335,"journal":{"name":"Saudi Journal of Oral Sciences","volume":"1 1","pages":"169 - 173"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90513913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
