Purpose: to restore the continuity and functions of the mandible after segmental mandibulectomy for mandibular defect reconstruction by using a technique of transport distraction osteogenesis with stem cells injection. Subjects and methods: Clinical study was conducted on eight patients suffering from mandibular deficiency after tumor resection. All steps of manufacturing of the transport distractor, tumor resection and segmental mandibulectomy of transport disc were guided by Stereolithographic (STL) model. Stem cells sample was prepared to be injected along the soft callus at the end of the activation period. Patients were followed up postoperative clinically every week and radiographically by Panoramic x-ray and computed tomography (CT) at immediate postoperatively, then by panoramic x-ray monthly along the periods of distraction and finally by multi slice CT at the end of the consolidation to evaluate the time consuming for treatment. Results: seven cases out of eight cases recorded excellent distraction regenerate and excellent soft tissue coverage and one case out of these eight cases in the control group failed at the first week of activation. Multi slice CT showed a significantly higher value in the mean of the regenerated bone density at the end of the consolidation (1163.76±111.38) in the study group than the control group (747.67±268.6). Conclusion: From our study, stem cells injection in the distraction regenerate for reconstruction of mandibular defect cases achieved short consolidation period and high regenerated bone density.

Purpose: This study was performed to evaluate the effect of PEEK reinforced mandibular implant overdenture, in comparison with metal reinforced mandibular implant overdenture on bone height. Subjects and methods: Fourteen completely edentulous patients were selected with ages ranging from 50-70 years. All the patients received two implants in the inter-foraminal area of the mandible and maxillary complete dentures, then they were divided into two groups: group (I) seven patients received PEEK reinforced mandibular implant overdentures, group (II) seven patients received metal reinforced mandibular implant overdentures. The overdentures were functionally loaded after three months of implant insertion and retained with the implants using ball and socket attachments. Evaluation of crestal bone height changes around the implants and in the distal aspect of the ridge was done by CBCT at the time of denture insertion, 6 and 12 months. Results: The results revealed that there was a statistically significant decrease in amount of crestal bone loss in PEEK group than in metal group after 6 and 12 months. The results also showed that, there was non significant difference when comparing the changes in the distal bone height after 6 months then, there was a statistically significant decrease in amount of distal bone loss in PEEK group than in metal group after 12 months. Conclusion: PEEK reinforced implant overdentures have better results than those reinforced with metal, as they recorded favorable radiographic outcomes after one year of overdenture insertion regarding crestal and distal bone height changes.

Purpose: The current study aimed to compare the efficacy of injectable hyaluronic acid gel and injectable platelet rich fibrin, either alone or combined; for the reconstruction of defective interdental papilla using clinical approaches. Subjects and Methods: A total sample size of eighteen class I and class II deficient interdental papillae sites were randomly divided in 3 groups. Group 1 included 6 sites that were treated by 0.2ml hyaluronic acid gel injection. Group 2 included 6 sites that were treated by injectable platelet-rich fibrin (i-PRF). Group 3 included 6 sites that were treated by a combination of 0.2ml hyaluronic acid gel injection and iPRF. Each deficient papilla received 3 injections; at 0, 3and 6 weeks intervals. The height of black triangles was recorded at baseline before injection procedure, at each injection interval and during follow ups. Results: A statistically significant difference in all three groups was found in the mean of the black triangle height records between the five time intervals, mainly between baseline and 6 months follow up. Conclusion: Hyaluronic acid injections and injectable platelet rich fibrin can be an alternative non-invasive treatment method for gingival black triangles.

Purpose: The aim of this study was to evaluate the marginal and internal fitness of PEEK and Zirconia crowns fabricated by three different impression techniques. Materials and methods: Thirty standardized acrylic die models were prepared. Dies were divided into two main groups (n= 15): Group 1: CAD/CAM fabricated zirconia crowns. Group 2: CAD/CAM fabricated PEEK crowns. Each group was subdivided into three subgroups (n= 5), according to the impression technique using for data acquisition: Sub-group (A): direct digital scans of the model used intraoral digital scanner. Sub-group (B): indirect digital scans of the silicon impressions using extraoral scanner. Sub-group (C): indirect digital scans of the stone casts obtained from silicon impressions using extraoral scanner. Crowns were then designed and fabricated. Marginal and internal gaps were measured using silicone replica technique and field digital microscope. Results: Independent t-test was used for comparison between groups. Comparisons between subgroups were performed by one-way analysis of variance (ANOVA) test, followed by Bonferroni’s post hoc test. In Zirconia group, the highest mean value was recorded in stone cast scan group, followed by intraoral scan, with the least value recorded in impression scan subgroup. In PEEK group, the highest mean value was recorded in stone cast group, followed by impression scan, with the least value recorded in intraoral scan subgroup. Conclusions: All tested crowns showed marginal gap distance values within the clinically acceptable levels. PEEK crowns had lower vertical marginal gap distance than zirconia crowns with different scanning techniques.

Licorice aqueous root extract rapidly rise salivary PH.","PeriodicalId":472826,"journal":{"name":"Al-Azhar Journal of Dentistry","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135628892","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}
Purpose: To evaluate the clinical and the radiographic outcomes of indirect pulp treatment (IPT) in primary molars using Calcium Hydroxide, Resin Modified Glass Ionomer and TheraCal LC. Subjects and Methods: Sample of 45 children aged from 4-8 years with deep carious one or more primary molars allocated randomly into 3 groups according to the capping material. Group I: Calcium Hydroxide (Dycal). Group II: Resin Modified Glass Ionomer (Vitrebond) and Group III: TheraCal LC. Teeth were treated then restored with EQUIA Forte HT in one visit and evaluated clinically and radiographically after three and six months. Results: The overall clinical and radiographic success rates were (88.2%) for Dycal group, (94.1%) for Vitrebond group and (100%) for TheraCal LC group. Results showed no statistically significant difference between groups in the overall clinical and radiographic success at 3 and 6 months. Conclusions: The indirect pulp treatment may be considered an appropriate procedure when applied on deeply carious primary teeth without irreversible pulpitis to achieve acceptable therapeutic results.
目的:评价氢氧化钙、树脂改性玻璃离聚体和TheraCal LC在磨牙间接牙髓治疗(IPT)中的临床和影像学效果。对象与方法:选取45例4 ~ 8岁单侧或多侧乳牙深龋患儿，根据牙盖材料随机分为3组。第一类:氢氧化钙。第二组:树脂改性玻璃离聚体(玻璃体键)和第三组:TheraCal LC。在一次访问中使用EQUIA Forte HT对牙齿进行治疗和修复，并在3个月和6个月后进行临床和影像学评估。结果:Dycal组的临床和影像学总成功率为88.2%，Vitrebond组为94.1%，TheraCal LC组为100%。结果显示，在3个月和6个月时，两组之间的总体临床和放射学成功率无统计学差异。结论:对于无不可逆性牙髓炎的深龋乳牙，采用间接牙髓治疗可获得满意的治疗效果。
