It has many advantages including anti-inflammatory, anti-fibrotic and antimicrobial properties. The purpose of the present work to study the effect of lyophilized human amniotic membrane on healing of bony defect in rabbits' femur. Eighteen male rabbits were used. Four mm wide and 5 mm deep defect was created in the femur diaphysis bilaterally in each rabbit. The defect of the right side was left empty (control), while the left side was filled with the amniotic membrane (study). Six rabbits were scarified at each of the experimental periods 2, 4 &amp; 6 weeks postoperatively. The defect areas were dissected out and evaluated histologically &amp; histomorphometrically. In the control group, at 2 weeks, woven bone spicules were seen extending from the periphery of the defect boundaries. At 4 weeks, the newly formed bone became more mature. At 6 weeks, the newly formed bone was more dense with newly formed osteons were seen. However, in the study group, the newly formed bone was much less in relation to the control group. Remnants of the amniotic membrane was seen folded at the center of the defect area surrounded by inflammatory cells. Histomorphometrically, the mean percentage of bone surface area in control group was higher than the study group in all experimental periods and the difference was statistically significant (p &lt; 0.001). It was concluded that: freeze dried amniotic membrane is not suitable to enhance bone healing when used as a filling material in bone defects.</p></div>","PeriodicalId":100562,"journal":{"name":"Future Dental Journal","volume":"4 2","pages":"Pages 205-210"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.fdj.2018.07.003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91262064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Group B to be restored with light nanocomposite resin (Filtek Z350 XT, with post-restoration bleaching procedure (Experimental). Group C to be restored with microhybrid resin (Filtek 250 XT) with no post-restoration bleaching procedure (control). Group D to be restored with microhybrid resin (Filtek 250 XT), with post-restoration bleaching procedure (Experimental). The bleaching was made with 15% at home bleaching agent (Opalescence PF). Color, opacity and fluorescence were analyzed by taking digital photos for the specimens at baseline and 24 h after completion of the bleaching procedure. The color pattern was evaluated according to the CIE - L*, a* and b* color system. Bleaching according to the following equation (25) ΔE = [(ΔL) 2+(Δa) 2+(Δb) 2] 1/2 For optical analysis, the specimens were subjected to the color measurements on white and black patterns, considering only the L* coordinate, which was calculated according to the formula: Opacity = L*b/L*w, where L*b corresponds to the reading of the L* coordinate against a black background and L*w against a white background. This procedure was performed before after bleaching, and the difference in opacity between the two periods was calculated in percentage. While for fluorescence comparison, the Fluorescence parameter (FL) was calculated, at baseline and post bleaching procedure, as the difference in color (ΔE) depending on the inclusion or exclusion of the UV component according to the equation: FL = [(CIE L*100 – CIE L*0) 2 + (CIE a*100 – CIE a*0) 2 + (CIE b*100 – CIE b*0) 2] 1/2, where subscripts 100 and 0 denote the 100% UV-included and the UV-excluded conditions respectively.
