Materials and Methods : In this study, fifty extracted premolars were allocated evenly into five groups of 10 teeth each. Group A: teeth treated with 0.5% Ashwagandha-based mouthwash (n=10); Group M: teeth treated with 0.5% Maca-based mouthwash (n=10); Group G: teeth treated with 0.5% Ginger-based mouthwash (n=10); Group F: teeth treated with Fluoride-based mouthwash as a positive control group (n=10); and Group C; negative control group: teeth not exposed to any treatment and stored in artificial saliva. All teeth were evaluated using the DIAGNOdent pen® at baseline, after demineralization, and after 14 days with different remineralizing materials. The antimicrobial properties of fluoride and plant extracts against Streptococcus mutans and Lactobacillus acidophilus were quantitatively evaluated by an antimicrobial susceptibility test. The data were statistically analyzed using an ANOVA test. Results: All experimental treated groups confirmed a reduction in DIAGNOdent pen® values. Group G showed the most significant decrease (-8.3±2.16), followed by Group M (-7.3±0.82), and Group A (-7.3±1.25), then Group F (-6.5±0.53). The lowest reduction was observed in the control group (-3.60.97). The distinction between groups was statistically significant (p=0.000). All used mouthwashes had antibacterial properties against Streptococcus mutans and Lactobacillus acidophilus bacteria, with no statistically significant difference. Conclusion: Herbal-based-mouthwashes of 0.5 % Ashwagandha, Maca, and Ginger are effective remineralizing agents on initial enamel carious lesions with antimicrobial activity against Streptococcus mutans and Lactobacillus acidophilus.","PeriodicalId":11504,"journal":{"name":"Egyptian dental journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140797196","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}

Twenty files of each system were used. Ten of them were used at room temperature and ten were used at body temperature. Dynamic cyclic fatigue testing was performed with a specific device, which allowed the instruments to rotate freely inside a Stainless-Steel artificial canal while providing an axial movement with amplitude of 3mm up and down movement. The time was calculated until instrument fracture occurred. A Sample with weight 10 to 15 grams of each instrument was evaluated using Differential Scanning Calorimetry (DSC).The DSC analyses were conducted over a temperature range from 0°C to 60°C . The results showed that HyFlex CM exhibited higher cyclic fatigue, followed by Fanta(AH wire), while soco showed the lowest values for both room and body temperatures. Temperature showed an effect (between body and room temperature) on cyclic fatigue resistance of some of CM wire type of instruments (Fanta and soco files).The differential scanning calorimetry confirmed the presence of the martensitic R-phase in Hyflex CM in both body and room temperatures which improved the cyclic fatigue resistance of this file, while presence of the martensitic phase only in room temperature for Fanta and Soco files not in body temperature which significantly decreases their cyclic fatigue resistance.","PeriodicalId":11504,"journal":{"name":"Egyptian dental journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140768435","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: Twelve identical models, fabricated by 3D printing, representing Kennedy class I mandibular partially edentulous cases with bilateral first premolars as primary abutments were used. Each model had four removable dies; canines and first premolars bilaterally. On these dies, bilateral splinted crowns were fabricated and grouped according to the extra coronal attachment material used (PEEK/BioHPP, zirconia and metal). Each group included four models, each model was designed having four slots for strain gauges (two on each side). These slots were positioned 1mm distal to the 1 st premolar (SG1 and SG3) and at the edentulous ridge (SG2 and SG4) 1 cm away from the first one. Removable partial dentures were fabricated, and a universal testing machine was employed to assess the strain induced under unilateral and bilateral loading conditions. This assessment was conducted both prior to and after clinical simulation for one year. The clinical simulation involved chewing simulator sessions and cycles of insertion and removal for the denture. Results: PEEK (BioHPP) group exhibited the least strain induced, both prior to and after clinical simulation for one year, under both unilateral and bilateral loading conditions. Conclusions: PEEK (BioHPP) extra coronal attachment used for retaining removable partial denture provides more favorable stress dissipation in comparison to zirconia and metal attachments.","PeriodicalId":11504,"journal":{"name":"Egyptian dental journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140757038","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: This study was conducted on 18 patients. The patients were distributed in two groups. All patients were with mandibular completely edentulous arch and were rehabilitated with five intra-foraminal implants which were restored by implant supported fixed hybrid prosthesis. For the first group: (C) canine guided occlusal scheme was used. As for the second group: (G) group function occlusal scheme was used. The amount of marginal bone loss in each group was measured by CBCT at 0, 6 and 12 months after delivery. Results: Within both intervals, for left implant (1) and right implant (2), distal bone loss values measured in group function group were significantly higher than those in canine guided group (p<0.05). While for other implants the difference was not statistically significant (p>0.05) at the end of the study. There was no significant difference between total bone loss values measured in both groups (p>0.05) at the end of the study. Conclusion: Both canine guided and group function occlusion are accepted occlusal schemes for fixed implant prosthetics, but canine guided occlusion tends to distribute the forces more evenly leading to more even bone loss than group function which concentrates stresses on the distal implants threatening the longevity of the distal implant.","PeriodicalId":11504,"journal":{"name":"Egyptian dental journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140771577","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}

Methodology : 45 systemically healthy individuals were subdivided into three groups: Group I: 15 Healthy participants without any oral lesions. Group II: 15 Patients having atrophic/erosive oral lichen planus (OLP). Group III: 15 Patients having oral leukoplakia. Enzyme linked immune-sorbent assay (ELIZA) kit was used to evaluate the level of LL-37 in whole unstimulated salivary samples collected from all participants. To reveal AUC, sensitivity, specificity, and diagnostic accuracy of LL-37 receiver operating curve (ROC) analysis was done. Results : The highest salivary level of LL-37 was revealed in OLP patients followed by oral leukoplakia patients whereas it was the lowest in healthy controls. ROC analysis exhibited excellent diagnostic accuracy of salivary LL-37 in differentiating both OLP and leukoplakia from control and OLP from leukoplakia. Conclusions : LL-37 appears to have a potential role in potentially malignant lesions (OLP & leukoplakia). The remarkable diagnostic accuracy of salivary LL-37 in differentiating potentially malignant lesion and healthy control could confirm its utilization as an innovative marker to early diagnose potentially malignant lesions. Salivary LL-37 being non-invasive accurate marker could be a chair-side diagnostic method that detect potentially malignant lesions.
