Aims: To evaluate in vivo the biocompatibility of newly prepared calcium oxide based nanosealer. Materials and Methods: Twenty albino healthy male rabbits were used, each received three polyethylene tubes; one filled with BioRoot sealer (+ve control), one received the newly prepared nanosealer, and the last left empty served as (-ve control) were implanted in the corresponding skin pockets made at the dorsal skin of the anesthetized rabbits. Then the rabbits divided into four equal groups according to the observation periods. Tissue biopsies were collected at (3, 7, 14, and 28) day after the implantation. The specimens were processed and stained with hematoxylin and eosin and examined microscopically. Statistical analysis was performed by Kruskal Wallis and Mann-Whitney tests for analyses the inflammatory tissues response of each group at observation times. Results: Histopathologically; at 3 days (-ve) and (+ve) control groups revealed sever inflammatory reaction, while the experimental group represented moderate tissues inflammation. These inflammatory tissues reactions were reduced over times for all group until subsided completely at 28 days but still faster for experimental sealer. All groups revealed thin full organized fibrous capsule at 28 days representing the tissues tolerance of implanted materials. Statistically the experimental nanosealer represented the least inflammatory tissue reaction among groups. There were no statistically significance differences in fibrous capsule thickness among the groups. Conclusions: The prepared nanosealer represented high biocompatibility than other groups.

The management of patients with severe worn dentition due to bruxism often necessitates an esthetic and functional approach. It is often challenging for the dentist, the dental technician, and the patient because of the loss of occlusal vertical dimension, loss of tooth structure, incorrect plane of occlusion, and para-functional habits.Bruxism has a considerable negative impact on teeth and increases odds of failure for ceramic restorations, especially fracture and chipping failures. The choice of an appropriate material is essential to improving treatment prognosis and should be guided by mechanical and aesthetic properties. In This clinical report, we describe the successful use after two years of a CAD/CAM monolithic Zirconia as a permanent solution for a female patient with severe bruxism.

Aims: The current study aimed to evaluate and compare the effects of the herbal medicaments (Neem, Ginger, Green tea, Clove oil, and peppermint oil) and traditional fluoride gel on the surface roughness of the eroded enamel samples of permanent teeth in vitro study. Materials and methods: A total of (80) sound maxillary permanent first premolars were used in the study. Enamel blocks were prepared and divided into eight groups: Negative control group (C-ve) (n=10) not exposed to Pepsi drink. The remaining samples exposed to Pepsi drink then subdivided into (7) subgroups: Positive control group (C+ve) (Pepsi group), the remaining groups representing different experimental remineralizing agents used as follows: Group 3 (NaF gel), Group 4 (Neem), Group 5 (Ginger+ Manuka honey), Group 6 (Green tea), group 7 (Clove oil) and group 8 (Peppermint oil). The Roughness of enamel surface blocks was measured before and after the PH cycle by using a measurement machine. Results: The surface roughness of all study groups was increased after eroding by Pepsi drink due to the demineralization, then decreased after treatment with remineralizing agents but the highest decrease of the surface roughness measurements belonged to the NaF group followed by Neem and Ginger +manuka honey groups, while the control negative group of deionized water which not exposed to Pepsi drink had no change in the surface roughness measurements. Conclusions: NaF gel group was significantly better than other groups against demineralization and preserving enamel roughness.

Aims: Assessment of Biphasic Calcium Phosphate mixed with injectable platelet rich fibrin (i-PRF) on healing of surgically created bone defects in a sheep animal model. Materials and Methods: In each tibia / radius of five sheep, three defects each measuring 7mm in diameter and 4mm in depth were created. The defects were filled with study materials and in the following order: from a proximal to distal orientation; first defect was filled with biphasic calcium phosphate alone, second left empty to be filled by physiological clot and the third with i-PRF mixed with biphasic calcium phosphate. Histological examination of bone defects was made to assess bone formation at fourtime intervals (two, four, six and eight weeks) post-surgically. Results: Regarding bone formation, histological findings showed the presence of a significant difference within the time intervals in the BCP+i-PRF group and in the BCP group when compared with control group with the highest mean being at eight weeks post-surgery in the BCP+i-PRF group. Conclusions: Both BCP and i-PRF, enhanced bone formation when compared to the control group and throughout the period of study and as disclosed by histological findings.

Aims: To assess bone density means with Biphasic calcium phosphate alone or mixed with injectable platelet rich fibrin in bone defects created surgically in sheep’s tibia / radius using standard radiographic assessment. Materials and Methods: Three bony defects of 4mm full and 7 mm in diameter were created in every tibias/radius of five sheep. The defects were stuffed within the following order: from a proximal to distal orientation; 1st defect was full of biphasic calcium phosphate alone, second left empty to be filled by physiological clot and also the third with i-PRF mixed with BCP and covered with absorbable collagen membrane for tissue guiding and then sutured. Densitometric analysis of bone defects was made to measure density of bone at four-time intervals (two, four, six and eight weeks) post-surgically. Results: Densitometric analysis results showed a major distinction within the BCP+i-PRF group and BCP group compared with the control one and at all-time intervals with the best density being in the 1st group followed by the BCP alone group and least in the control group. Conclusions: BCP and i-PRF, both of them increased and sustained bone density (synergistic effect) throughout the study period and as revealed by densitometric data.

Aims: To evaluate the efficiency of Er,Cr: YSGG laser in debonding of veneers made of lithium disilicate (E-max®) as measured with the shear bond strength(SBS), determine the impact of two laser powers on the SBS required to debond veneers, and finally determining the mode of failure for each group. Materials and methods: Thirty ceramic discs (1mm in thickness and 5mm in diameter) were prepared according to the manufacturer’s instructions. The facial surfaces of enamel for thirty bovine teeth were prepared smooth and the discs cemented onto these prepared surfaces by using G-Cem™ veneer light cure adhesive cement. Specimens were stored in distilled water for 48hours, after which they were divided randomly into three equal groups (n=10) according to the laser power used as follows: Cont.: Control group that wasn't subjected to laser irradiation; L3: Group irradiated at 3 watt (60 sec.); L5: Group irradiated at 5 watt (60 sec.). SBS was measured by “Instron universal testing machine” and the mode of failure was assessed using stereomicroscope. Results: Both laser irradiated groups showed significant difference in reducing the SBS (p=.000), some of discs debonded during laser irradiation. However, there was no significant difference between the two laser powers used (p=.418). Conclusions: Er, Cr: YSGG could be a safe, effective, fast, and harmless method for reducing SBS of bonded E-max® laminate veneers, without affecting the tooth and the veneer itself. Since there was no significant difference between the two laser powers used, it is advocated to use 3 watts.

Aims: Evaluation of the surface hardness of heat-treated acrylic resin after modifying it with three different techniques. Materials and Methods: Heat cured acrylic resin was modified by: (a) The copolymerization of acrylic resin with 5% and 10% of acrylic acid (AA), (b) The addition of 5% and 10% thermally activated zinc oxide (ZnO) and (c) The chemical bonding or engagement of Zinc ions into the polymer chain by an organic link, zinc diacrylate (ZDA) in 5% and 10%, to get a copolymer. The acrylic specimens have dimensions of (30, 15 and 3) ± 0.2 mm. Surface hardness was determined using a Durometer (Shore D) hardness tester. Results: There was general increase of the surface hardness of the experimental (modified) groups. A statical significant increase in the hardness of both acrylic groups modified by 10% ZnO and 10% ZDA compared to the control group and the remaining modified samples. Conclusion: Two techniques had significantly improved the hardness of heat cured acrylic resin; either by adding 10% by weight of thermally activated ZnO or by copolymerizing it with 10% by weight of ZDA to get poly (methyl methacrylate -co-zinc acrylate) copolymer.
