The lower dentures were subjected to microwave radiation 700 Watt for three minutes once a week for four successive weeks in a dry condition. Twenty maxillary denture bases were constructed and lined with soft liner, the gap between the lined denture base and the stone cast was measured at the posterior palatal seal area at three different points, as well as the occlusal pattern before and after exposure to microwave radiation. Results: there were no significant effect for using microwave radiation on the lined denture regarding occlusal force distribution and dimensional changes. Conclusion: lined denture disinfection by microwave energy at 700watt for three minutes has no statistically significant effect over the dimensional changes and occlusal force distribution.","PeriodicalId":7493,"journal":{"name":"Al-Azhar Dental Journal for Girls","volume":"1995 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82444240","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}

Materials and Methods : one human upper first premolar was prepared and duplicated using epoxy resin to produce twenty one dies. Accordingly, a total of (N=21) provisional crowns were constructed. The Constructed provisional restorations were divided into 3 groups according to the method of construction (n=7 for each group), Group 1: Provisional crowns were constructed using conventional manual technique, Group2: Provisional crowns were constructed using CAD/CAM milling technique, Group3: Provisional crowns were constructed using 3D Printing technique. All Provisional crowns were bonded to their corresponding epoxy resin dies by using CharmTemp ZONE temporary cement and subjected to thermocycling procedure simulating approximately one month of clinical situations Results: Statistical analysis showed that the fracture resistance of CAD/CAM samples (group 2), recorded the statistically significant highest mean fracture resistance value (910.20 ± 118.95), followed by 3D Printing samples (group 3) (720.80 ± 129.57), while the lowest value was recorded for Conventional samples (group 1) (626.71 ± 103.23). ANOVA test showed that there was no significant difference between 3D Printing samples (group 3) and Conventional samples (group 1).

Material and Methods: 48 adult male albino rats were used in this study throughout the experimental period (2 weeks). 12 rats were left as negative controls (G I) and the remaining experimental 36 rats were treated with 5-fluo-rouracil (chemotherapeutic agent) in a dose of 50 mg/kg/dose to induce oral mucositis. Moreover, acetic acid was injected in the buccal mucosa to produce ulcers and then the rats were subdivided into three subgroups, (G II) in which 12 rats received no treatment, (G III) in which 12 rats received a direct injection of a single dose of adipose-derived stem cells, (G IV) in which 12 rats received an intravenous injection of a single of adipose-derived stem cells. All rats were euthanized; cheek epithelium was dissected and processed for hematoxylin & eosin evaluation. Results: Group III produced better healing than group IV where the ulcer appeared covered with a continuous layer of regenerated epithelium after one week in group III while the regenerating epithelium failed to cover the ulcer in group IV. After two weeks, the epithelium covered the ulcers in both groups but the C.T. architecture appeared better in group III. Conclusion: The direct injection of ADSCs in oral mucositis produces faster healing potentiality than intravenous injection.","PeriodicalId":7493,"journal":{"name":"Al-Azhar Dental Journal for Girls","volume":"138 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80267404","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 aim of the study was to evaluate patient satisfaction with two maxillary complete dentures constructed for each patient, one using the windows impression approach with a custom-made dual tray and the other using the conventional impression technique with a custom single tray. The time interval for using each set was about 3 and 6 months. Patients’ satisfactions were assessed at every time interval. Data was analyzed to determine the patient satisfaction with the different complete dentures using the SPSS.ver.23 and Wilcoxon signed rank test at (α = 0.05). Results: Patients’ satisfaction survey showed that the 2 different maxillary dentures were not statistically equivalent, where the maxillary complete denture constructed with windows technique using the dual custom tray demonstrated greater patient satisfaction. Conclusion: Within this study, complete denture constructed with windows technique using the dual custom tray improves the denture function and subsequently the patient satisfaction.","PeriodicalId":7493,"journal":{"name":"Al-Azhar Dental Journal for Girls","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85928592","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}

After three months of osseointegration, each patient received two mandibular overdentures; one was metal reinforced (Group I) , and the other was PEEK reinforced (Group II) . Masticatory efficiency for both groups (I & II) was carried out. Masticatory efficiency was measured by two colored chewing gums test at time of each overdenture insertion (T0). Thereafter, masticatory efficiency was evaluated subsequent to three months of using metal and PEEK reinforced overdentures (T3). Results: In regard to masticatory efficiency, no significant difference was noted between the studied groups reinforced with metal or PEEK at (T0) and three months after insertion (T3). Among chewing strokes, significant differences were revealed between varied chewing stroke counts among both groups (increased chewing efficiency with an increased number of chewing strokes). Conclusion: Respecting single midline implant overdenture, there was no significant difference between (Metal & PEEK) reinforcement regarding masticatory efficiency.

Materials and methods: Periodontal ligament fibroblasts were obtained from 30 freshly extracted sound premolars and cultured in Dulbecco’s Modified Eagle Medium (DMEM). Cell viability was determined by storing the cells in Hank’s balanced salt solution (Group I), Green tea extract (Group II) and fresh Dulbecco’s Modified Eagle Medium (DMEM) (Group III) as positive control, for 1,3,6,12,24 and 48h at 37 o C using MTT assay (3-[4,5- dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide). Results: Statistical analysis was performed by one-way analysis of variance (ANOVA) and post hoc tests. The findings of this study revealed that there was no significant difference between groups at 1h and 3h time intervals, while GTE showed considerably better protective effect than HBSS at 6 hrs.
