Purpose: This study aimed to compare between Propolis and Triple Antibiotic Paste as root canal medicaments in eradication of Enterococcus faecalis. Material and Methods: for this study, 60 extracted human teeth were used. After their decapitation, they were initially instrumented to reach 20 K-file, later they were separated into 2 sets according to the medicament used; Group A1: Triple antibiotic paste Group A2: Propolis paste (30 specimens in each group). After sterilization of all samples inoculation was performed with Enterococcus faecalis (ATCC29212) over a period of 21 days. Preparation of all samples was done using Step- back technique to reach #50 file, irrigation using sodium hypochlorite solution of 2.6% concentration and EDTA, then intracanal medicaments were applied. First sample (S1) was collected after inoculation of bacteria into root canals. Second sample (S2) was collected after undergoing instrumentation and irrigation. Third sample (S3) was taken following application of medicament. Fourth sample (S4) was taken following application of sterile cotton pellet and temporary restoration for seven days. BHI agar was used for culturing of samples then went under incubation to count CFU's. Results: There was a significant difference between different samples where (p ≤ 0.05) and there was a continuous decrease of (mean ±SD) value starting from (S1) till (S4). Pairwise comparisons for both medicaments showed all samples to be significantly different from each other. Conclusion: Antimicrobial activity of Propolis against E. faecalis was found to be greater than that of TAP and can be used as a short-term intracanal medicament.

Purpose: The aim of the study was to evaluate and apply a minimal invasive approach for reconstruction of atrophic maxilla using computer-guided implant surgery by zygomatic implants combined with conventional implants. Material and methods: 10 patients with severely atrophic edentulous upper arch were included in this study, each patient had 2 conventional implants placed in the anterior maxilla, and 2 zygomatic implants on either sides placed in the zygomatic bone. In all patients a computer guided approach using a computer guided stent was used for drilling the conventional and zygomatic implants. All patients followed a clinical and radiographic follow up Result: Zygomatic Implants success was 90.0% while conventional implants success was 80.0%. The mean ± standard deviation values of coronal deviation were 3.24 ± 1.9 mm for Zygomatic implants and 2.9 ± 2.5 mm for conventional implant. The mean ± standard deviation values of apical deviation for were 4.2 ± 2.5 mm for zygomatic implants and 2.6 ± 2.5 mm for conventional implants. The mean ± standard deviation values of bone implant contact for zygomatic implant were 19.5 ± 5.3 mm, the bone covering the zygomatic implant laterally were 6 ± 2.3 mm, the minimum distance from the orbit were 5.6 ± 3.2 mm. General satisfactions for the treatment was 8.6. Conclusion: The use of zygomatic implants combined with conventional implants using virtual computer guided planning and surgery was useful for reconstruction of atrophic maxilla allowing an accurate, safe, graft less, less invasive surgery and provided a high patient satisfaction.

Purpose: the objective of the present study was to evaluate the effect of BM-MSCs on irradiated submandibular salivary glands in mice and to determine at which stage post-irradiation the cells should be transplanted. Materials and methods: 58 adult male mice were used, 10 for preparation of PKH-26-labeled BM-MSCs and the remaining 48 mice were divided into: control group (GӀ) consisted of 6 mice without radiation and experimental groups consisted of 42 irradiated mice irradiated with a single dose of 15Gy. They were randomly divided into three groups: GӀӀ (+ve control): 18 irradiated not treated mice and two treated groups each consisted of 12 irradiated mice and treated with intraglandular injection of labeled BM-MSCs, 24 hours (GӀӀӀ) and at day 11 (GΙV) post-radiation. Animals were sacrificed at day 6, day 30 and day 90 post-radiation. The submandibular glands were collected, one gland was routinely processed for histological examination using H&E staining and the other was prepared for immunohistochemical study using immunofluorescence staining with anti- α-amylase 1 antibody. Results: BM-MSCs produced marked improvement in salivary gland tissue architecture, histology of parenchymatous and stromal structures and glands function indicated by marked increase in α amylase 1 production compared with +ve control group, with GӀӀӀ showed greater improvement than GΙV. Conclusions: It could be concluded that: intraglandular transplantation of BM-MSCs could successfully regenerate radiation-induced submandibular salivary gland damage and restore the gland function. The early transplantation of BM-MSCs 24 hours post-radiation was markedly more beneficial than the transplantation at day 11 post-radiation.

The purpose of this study was to evaluate the effect of different occlusal concepts which are bilateral balanced occlusion, canine guided occlusion on masticatory efficiency, in implant supported mandibular over denture wearers.<br />Material and methods: ten completely edentulous patients were selected for this study, aged 50 to 60 years old. All patients free from any systematic dieses. The patients were divided into three groups according to the treatment protocol; {GI} All patients wore denture with intra oral adjustment, {GII} five patients wore denture with bilateral balanced occlusion and {GIII} five patients wore denture with canine guided occlusion. All patients were submitted to masticatory efficiency test, after one month by using different textures of foods. The recordings data were analyzed using ANOVA. This was followed by Tukey’s post hoc test using LSD test. P< 0.05 was considered statistically significant. Results: with soft food, there was non-significant difference between the three groups, while with hard food; the greatest mean was recorded in occlusion after oral adjustment, whereas the lowest mean was recorded in bilateral balanced occlusion. Conclusion both bilateral balanced occlusion and canine guidance occlusion can be used successfully in implant supported overdentures without affecting masticatory function.

Aim:This study was designed to evaluate the resistin levels in GCF of patients with periodontitis and type 2 diabetes mellitus(T2DM) after non-surgical periodontal therapy and subantimicrobial dosage doxycycline(SDD).Subjects & Methods:Thirty periodontal sites within 24 patients with age ranged between(24-51) years old were selected for this study.Total of 30 periodontal sites were randomly divided into three groups;each group included ten periodontal sites:(group I):systemically healthy periodontitis patients who were received scaling and root planning (SRP),(group II):periodontitis patients with T2DM who were received SRP, and(group III):periodontitis patients with T2DM who were received SRP and SDD 20mg twice/day. All patients were examined with clinical periodontal parameters: plaque index(PI), gingival index(GI), probing depth(PD) and clinical attachment level(CAL).Patients in each groups underwent nonsurgical periodontal therapy combined with a maintenance program (including brushing with regular toothpaste). GCF samples were collected in all patients at baseline, one month as well as 3 months after periodontal therapy. Quantification of resistin in human samples was measured using resistin ELISA test. Results: Non-surgical periodontal therapy resulted in relative improvement in all clinical parameters as well as a decrease in resistin levels.In addition, GCF levels of resistin, PD , GI were greater reduction after non-surgical treatment in group III than group II.Conclusions:Non surgical periodontal therapy is found to be effective in the treatment of periodontitis patients with and without diabetes mellitus and also GCF resistin can be a useful biomarker to detect the periodontal disease condition.Also, adjunctive use of SDD showed more clinical benefit to patients with periodontitis by host response modulation.

Aim: This study was designed to evaluate the influence of pre-flaring on the apical transportation and dentinal damage after preparation of curved root canals using EndoStar (ES5), OneShape (OS) and ProTaper Next (PTN) systems. Material and Methods: Hundred and twenty human mandibular first molars were selected. Pre-operative imaging by CBCT was done for measurement of apical transportation of mesio-buccal root canals then saved. The specimens were grouped into: Group I: Instrumented by ES5 files; Group II: by OS single file; and Group III: by PTN files. Each group was subdivided into subgroups: A: Instrumented without pre-flaring; and B: pre-flared before instrumentation. After instrumentation, all specimens were scanned under the same way as the pre-operative scan and data were saved on the software for evaluation of apical transportation. Roots were sectioned perpendicular to long axis at 3, 6 and 9mm from the apex and viewed under SEM for detection of any defect arise from lumen outwards. The significance was set at P < 0.05. Results: All values of apical transportation at level 2mm from apex were positive that indicated direction of transportation toward mesial direction of root canal, whereas at level 4mm from apex were negative that indicated direction of transportation toward distal direction of root canal. In dentinal defects at 6 mm, the higher percent of cracks was noted in OS and the lowest for PTN. Conclusions: Pre-flaring of root canal reduces the apical transportation and dentinal defects when curved root canals were prepared with Ni-Ti instruments.

Purpose: This study was conducted to compare between maxillary implant-supported overdentures retained by telescopic and ball and socket regarding retention. Material and Methods: seven male patients had completely edentulous maxilla free from any systemic disease that might affect bone metabolism was selected to participate in this study. Each patient received four dental implants in the edentulous maxilla using computer guided surgical stent. Implants had enough antero-posterior spread so that load can be distributed equally. Once the implant osseointegration appears to be satisfactory, the maxillary four implants were loaded with two different attachments as follow; Group I: All patients received maxillary single denture retained with ball and socket attachments and used it for three months. Group II: After a wash up period of two weeks, all patients received another newly constructed maxillary single denture retained with telescopic attachments and used it for another three months. Retention of both groups was measured using universal testing machine. The assessment was made at time of insertion, one month and three months follow-up period. Results: Group II showed higher retention values compared to Group I. Conclusion: ball and socket attachment as well as telescopic attachment showed decrease in retention but telescopic attachment revealed a higher score than ball attachment due to frictional retention.

• Purpose: evaluation the surface roughness of root canal surface and its correlation with Resin Sealer Bond Strength following final irrigation by apple vinegar. Materials and Methods: Fifty extracted lower premolars were prepared then the samples were equally distributed into 2 main groups . Group I: Apple vinegar , Group II: 17 % (EDTA), Control group : sterile saline. Each group was further distributed into .Subgroup A: For surface roughness evaluation(Ra). Subgroup B: For push out bond strength evaluation. Surface roughness was evaluated using digital microscope that is one of non contact optical microscope. The push out test was carried on using universal testing machine. The sealer penetration inside the dentinal tubules was evaluated using (SEM) . Results: the highest value of Ra was recorded in samples treated with 17% EDTA, while the lowest value was recorded with the control group . The highest value of bond strength was recorded in samples treated with 17% EDTA, while the lowest value was recorded with the control group . SEM observation of sealer/ dentin interface revealed few traces of sealer penetration with samples treated with 17% EDTA and AV. Conclusion: EDTA 17% as a final rinse produced higher value of surface roughness compared to AV. The effect of AV on the push out bond strength was comparable to that of 17%EDTA when used as a final rinse. There is a linear relation between Ra and the push out bond strength of resin sealer in Groups I, II.

Purpose: This study was designed to evaluate and compare the efficiency of piezoelectric device for implant site preparation clinically and radiographically. Materials and methods: The study included 12 patients divided into two groups. The group A received implants prepared with the conventional drills (CDs), while, group B, the piezoelectric devices (PEDs) were used. The stability of implant was measured, immediately, at 2 months, and 4 months after the implant insertion. Also, the drilling time was recorded. While, the Marginal bone loss (MBL) and Bone mineral density (BMD) were recorded immediately, at 3, and 6 months after implant insertion. Results: Group B had a significant higher ISQ values all over the follow up periods. The drilling time of ISP was significantly higher in group B. Regarding the MBL, there was no a statistical significant difference. The BMD increased significantly in group B immediately, and at 3 month. Conclusion: The osseointegration of implants prepared with PED was significantly greater than that of implants which prepared with the CDs all over the time points, but the PEDs need significantly longer surgical time than the CDs

Purpose: This study was assessed the efficacy of Apple vinegar as final irrigating solution in removing smear layer using XP-Endo Finisher File by scanning microscope. Material and Methods: Fifty single rooted lower premolars were selected and prepared using Universal ProTaper rotary files. Samples were divided into two main groups (I,II) regarding the final rinse used (20 samples each) and control group (10 samples): Group I: rinsed with 17% EDTA, Group II: rinsed with Apple vinegar and Control group: irrigated with sterile saline. Each group was subdivided into two subgroups (A,B) regarding the agitation file. Subgroup A: Conventional irrigation, Subgroup B: agitated with XP Endo Finisher. Samples were grooved longitudinally and smear layer was assessed. Results: no statistically significant difference in the median scores of smear layer produced by 17% EDTA and Apple Vinegar at coronal, middle and apical root levels when conventional irrigation or XP Endo Finisher were used. There was a significant difference between two irrigating techniques at apical level when 17% EDTA used as final rinse, where XP Endo Finisher showed statistically significant lower median score (P≤ 0.05). Conclusions: Apple vinegar presented similar smear layer removal efficiency from intraradicular dentin compared to 17% EDTA when used as final rinse. XP-Endo Finisher is a successful agitation system for removal of smear layer from intraradicular dentin.

Objectives: This study was designed to evaluate and compare Fluoride versus Bioactive Glass effect on Enamel after Cold Light Activated Bleaching and Chemical Bleaching. Materials and Methods: Forty specimens obtained from ten sound bovine central incisors were numbered from 1 to 40 and subjected to EDAX &SEM analysis. Specimens were divided into two main groups, the first group was subjected to chemical bleaching using 35% hydrogen peroxide gel and the second group was subjected to cold light activated bleaching using 25% hydrogen peroxide gel. After bleaching, EDAX & SEM analysis for all specimens was done. Each main group was subdivided into two groups according to the remineralizing agent used. The first subgroup was treated by fluoride gel and the second was treated by bioactive glass gel for 3 minutes twice daily for 10 consecutive days. EDAX and SEM were done for all Specimens after remineralization. Results: Calcium and phosphorus levels were significantly decreased after bleaching with both chemical and cold light bleaching techniques. Ca &p levels were significantly increased after using fluoride or bioactive glass. Higher remineralization results were obtained with bioactive glass. Bleached enamel appeared porous with multiple surface irregularities which disappeared after using fluoride or bioactive glass. Conclusion: In-office bleaching has deleterious effect on enamel surface causing decrease of calcium and phosphorus which can be reversed by using remineralizing agents. Bioactive glass has superior effect than fluoride in restoring enamel minerals.

Purpose: The aim of the present study was to evaluate the effect of artificial aging on the optical properties and flexural strength of ultra-translucent tetragonal/cubic zirconia. Materials and Methods: A total of 30 (N=30) ultra-translucent cubic zirconia discs (DD cube X2) were fabricated. Samples were divided into 3 equal groups (n=10) according to the aging protocol followed including Group (1): (control), samples were not subjected to hydrothermal aging protocol, (n=10), Group (2): Samples were subjected to one-hour hydrothermal aging protocol, (n=10), Group (3): Samples were subjected to 3 hours hydrothermal aging protocol, (n=10). Samples of each group were subjected to optical properties determination using spectrophotometer including (Translucency parameter TP, Contrast ratio CR, Change in color ΔE) and biaxial flexural strength determination using universal testing machine. Obtained values were statistically analyzed. Results: Statistical analysis using ANOVA test revealed no significant difference between the three tested groups. The highest mean value of translucency and biaxial flexural strength were recorded at the control group. While group (3) samples recorded the lowest mean values. Color change (ΔE) was performed for groups (2 and 3) to detect the amount of color change from control group. Group (3) samples recorded higher mean values than group (2) samples. Conclusions: Hydrothermal aging has no effect on the optical properties and flexural strength of tetragonal / cubic zirconia (DD cube X2).

Abstract:<br /> <br /> In order to simplify bonding procedures, self-etching adhesive systems have been implemented. It has less acidity than phosphoric acid, so there is a doubt whether these systems are strong enough for enamel bonding. This study is aimed at comparing the shear bond strength of various adhesive systems for pre-etched and non-etched enamel. This study used 60 human molars. Analysis of variance (ANOVA) has been used to assess whether the shear bond strength between the various groups have been significantly differing. The post hoc test of tukey’s had been evaluated. The p value was
