Objective: Currently, there is no recommendation for the minimum number of remaining walls for Zirconia endocrown. Materials and methods: Fifty resin specimens were divided into 5 main groups according to the remaining wall number; group W0 no remaining walls, group W1 1 remaining wall, group W2 2 remaining walls, group W3 3 remaining walls, group W4 no missing walls. Ten resin dies for each group were fabricated using epoxy resin and assigned to each group. Resin dies from all groups were individually scanned using an extraoral scanner. Second generation zirconia monolithic (three mol% yttria-stabilized tetragonal zirconia polycrystal (3Y-TZP) endocrowns were milled. All endocrowns were sintered according to the manufacturer’s recommendations. After trial fitting, all endocrowns were cemented to their corresponding resin dies using resin cement. After 1000 thermal cycles alternating between hot and cold baths with 20-second immersions at 55±1º C and 5±1ºC, respectively, and a 10-second delay between each immersion, each specimen was fixed to the lower fixed part of a universal testing machine with a load cell of 5 kN at a crosshead speed of 0.5 mm/min. All specimens were loaded to failure, and recorded in Newton using computer software. Data were collected, tabulated and statistically analyzed. Results: Group W1 showed higher mean values (2933±733.61) followed by W0 group (2453.5±492.48), then W4 group (2187±576) and group W2 (2108.17±451.28) and finally W3 group (1992±205.63). At a 95% of confidence level, One-Way ANOVA revealed significant differences between tested groups (P= 0.033). Conclusions: There was a significant difference in fracture resistance between groups with different numbers of remaining walls. The mean fracture resistance values were not consistent with the number of remaining walls. The number of remaining walls is not directly proportional to the fracture resistance values.

Objective: Evaluation the efficacy of 2.25% sodium hypochlorite gel and Brix 3000 in caries removal of deciduous teeth. Subjects and methods: Thirty-six primary molars (class 1) with depth of caries not more than the coronal two thirds of dentine thickness. The children were aged 4-7 years and randomly divided into three equal groups based on the method of caries removal. The time of caries removal in each tooth was calculated using a stopwatch and the mean time of each method was obtained. The physical pain was also assessed by asking the children to choose the face that express their feeling using the Wong-Baker FACES analysis scale. The children were recalled for clinical and radiographic evaluation after 1and 6 months. Results: The conventional method showed the shortest time (2.82±0.477 min.) of caries removal followed by Brix 3000 (5.47±1.35min.) and 2.25% sodium hypochlorite gel (7.24±1.45 min.). Concerning pain sensation; the conventional method showed the highest grade of pain sensation with high significant differences from the two other chemomechanical methods. The results showed no significant difference between 2.25% sodium hypochlorite gel and Brix 3000. The clinical and radiographic evaluation showed that there was no significant difference after 1 and 6 months between all groups. The success rate among these groups showed that there was no significant difference between the success rates in all groups. Conclusion: 2.25% sodium hypochlorite gel and Brix 3000 are effective chemomechanical caries removing agents.

Objective: The purpose of this study was to evaluate the stress distribution of fixed implant-supported prostheses using “all-on-four” concept for the treatment of mandibular completely edentulous ridge “in vitro study” by 3D finite elements analysis . Materials and Methods: The finite element model components as the overdenture, mucosa, implants, angled base, abutment, cortical and cancellous bones were created in “Autodesk Inventor, then exported as SAT files. These components were assembled in ANSYS environment. The model was subjected to two loading conditions of 200N, vertically unilateral and, vertically bilateral at molar regions respectively. Results: All values of deformations and stresses appeared on the model components (overdenture, implants, angled base, abutment, cortical and cancellous bones) were within physiological limits under all loads application. Conclusion: Tilted implants at molar area did not affect the system behavior (did not show peak of stresses or deformation) and all values of deformations and stresses that appeared on the model parts (cortical, spongy bone, implant, base, abutment, and overdenture) were within physiological limits under all cases of load application.

Objective: The objective of this in vitro study was to compare modulus of elasticity of CAD /CAM milled, 3D printed and flexible pressed resins. Materials and Methods: eighteen rectangular specimens with specific measurement (65mm X 10mm X 3 mm) were constructed from different resin denture base materials and divided into 3 groups (6 specimens for each group). Group I contained the CAD/CAM milled resin specimens, Group II contained 3D printed specimens and Group III contained polyamide flexible resin. The specimens were evaluated by the three-point bending test on universal testing machine (INSTRON) to calculated modulus of elasticity. Data was analyzed with ANOVA and Tukey’s pair-wise post-hoc tests. Results: The modulus of elasticity values of all groups ranged from 845.5 MPa to 2962.3 MPa. There were significant differences among the tested resin denture base materials. CAD/CAM milled materials had the highest modulus of elasticity, while the polyamide pressed materials had the lowest. The 3D-printed acrylics materials had lower modulus of elasticity values than CAD/CAM milled materials. Conclusion: The CAD/CAM milled and 3D printed denture base resins showed higher modulus of elasticity when evaluated with polyamide pressed materials.

Objective: This study aimed to assess the effect of diode laser irradiation (980 nm) and warm air drying (50°C) on shear bond strength between Lithium di-silicate and human dentin using both Etch & Rinse (ER) adhesive, Adper Single Bond 2 and Self-etch (SE) adhesive, Single Bond Universal before adhesive polymerization. Materials and methods: One hundred and eight sound lower molars were sectioned perpendicular to the long axis to obtain flat dentinal surfaces. Specimens were divided into 2 equal groups (n=54): Group 1 (ER) and Group 2 (SE) according to bonding approach. Each group was subdivided according to dentin moisture elimination technique into 3 equal subgroups (n=18): Control (Co), Diode laser irradiation (L) and Warm air drying (W). All specimens were adhesively cemented to IPS e.max® CAD discs using RelyX™ Ultimate Clicker™ (3M ESPE) resin cement. Half of the samples were then subjected to pre-loading in a thermodynamic manner (C=9). Afterwards, all samples were tested for shear bond strength using computer-controlled material testing machine. Results: Data analysis was performed using three-way (ANOVA) (p< 0.05) followed by pair-wise Tukey’s post-hoc tests. Three-way ANOVA showed significant difference between moisture elimination techniques in both groups, except ERNC. Also, for both groups, subgroup (W) had the highest shear bond strength values followed by (Co) subgroup and the least was (L) subgroup. Conclusion: Warm air drying for both bonding approaches increased shear bond strength of IPS e.max to human dentin and can be introduced to enhance bonding to dentin.
目的:在胶粘剂聚合前,采用蚀刻与冲洗(ER)胶粘剂Adper Single bond 2和自蚀刻(SE)胶粘剂Single bond Universal,研究激光辐照(980 nm)和热风干燥(50℃)对二硅酸锂与人牙本质剪切结合强度的影响。材料和方法:将108颗健康的下磨牙垂直于长轴切面,获得平整的牙釉质表面。按粘接方式将标本分为2组(n=54): 1组(ER)和2组(SE)。根据牙本质祛湿技术将各组再分为3组(n=18):对照组(Co)、二极管激光照射组(L)和热风干燥组(W)。所有标本均使用RelyX™Ultimate Clicker™(3M ESPE)树脂胶粘剂与IPS e.max®CAD椎间盘进行粘接。然后,一半的样品以热力学方式进行预加载(C=9)。然后,使用计算机控制的材料试验机对所有样品进行剪切粘结强度测试。结果:采用三向方差分析(ANOVA) (p< 0.05)进行数据分析,然后进行双配对的Tukey事后检验。三因素方差分析显示,除ERNC外,两组的除湿技术存在显著差异。两组剪切强度值均以W亚组最高,Co亚组次之,L亚组最低。结论:两种粘结方式的热风干燥均可提高IPS e.max与人牙本质的剪切粘结强度,可用于增强与牙本质的粘结。
