Purpose: To evaluate the effect of 3% green tea extract (GTE) on wettability, depth of penetration, and push out bond strength (PBS) of AH Plus sealer to intraradicular dentin following the use of 0.2% Nano chitosan or 17% EDTA. Materials and methods: Twenty human radicular dentin segments were used for wettability assessment. Following immersion in 2.6% NaOCl solution, samples were divided into 2 groups (n=10) according to the chelating agent used: group I: 0.2% Nano chitosan, and group II: 17% EDTA, each used for 3 min, then the contact angle (CA) was measured. The samples were further immersed in 3% GTE solution for 5 min followed by CA measurement. Twenty human mandibular premolars were prepared up to # X4 ProTaper Next files, then divided into two groups as mentioned previously. Each group was subdivided into two subgroups based on the final flush used (n=5); subgroups A and B; no treatment, and 3% GTE, respectively. Samples were obturated by cold lateral compaction using AH Plus sealer and gutta-percha. PBS was measured using a universal testing machine and sealer penetration was assessed using confocal laser scanning microscopy. Results: Using 3% GTE following the use of 0.2% Nano chitosan significantly increased the wettability and PBS of AH Plus sealer to intraradicular dentin, while its use following 17% EDTA significantly decreased the wettability and PBS of AH Plus sealer. Using GTE increased the maximum depth of AH Plus sealer penetration into the dentinal tubules. Conclusion: GTE improved the wettability, depth of penetration, and push out bond strength of AH Plus sealer to intraradicular dentin treated with Nano-chitosan. Nevertheless, it adversely affected those properties of AH Plus sealer to EDTA-treated dentin.

Purpose: The purpose of this study was to evaluate the caries removal using Er,Cr:YSGG laser and Papacarie chemo-mechanical caries removal (CMCR) method in primary teeth. Materials and Methods: Patients (4 – 8 years old) having 40 carious primary molars with dentin involvement were selected for this study. Caries was removed using two methods; Group 1 (Laser) Waterlase MD turbo Er,Cr:YSGG Laser using Quartz tips (MZ – 8) on the Gold handpiece and group 2 (CMCR) Papacarie Duo gel. Final restoration was done by Riva light cure Glass ionomer. Caries removal was assessed clinically by tactile and visual method (Ericson criteria). Time taken for the procedure was measured in minutes. Evaluation of pain perception was done using the Wong-Baker facial image. Microbiological evaluation was done by collecting dentin samples from the carious primary tooth before and after caries removal and total bacterial count was assessed. The restoration was evaluated using the United States Public Health Service (USPHS) at baseline, three months, six months and nine months. Results: The two groups showed a statistically significant difference (unpaired t test) in the time of treatment, Pain score and total bacterial count. Clinical evaluation of the restoration using the modified USPHS criteria showed no statistical significance between the two groups. Conclusion: Chemo-mechanical caries removal methods and laser irradiation are effective and efficient techniques for caries removal in children with high patient acceptance and no adverse effects.

Purpose: This study aimed to compare NiTi rotary systems of different wires namely; EdgeFiles, Profile GT series X (GTX) and ProTaper (PT) in terms of: canal transportation and centering ability. Materials and Methods: One hundred and twenty extracted human mandibular first molars were selected and randomly divided into two main groups (I&II) according to the ranges of curvature (60 teeth each), where group I: samples with 25o40o range of curvature and group II: samples with 45o60o range of curvature. Each group was subdivided into four subgroups according to the NiTi rotary system (15 teeth each): subgroup A: ProTaper, subgroup B: Profile GT Series X, subgroup C: EdgeFile X3 and subgroup D: EdgeFile X5. The root canals were scanned by i -CAT CBCT scanner before and after instrumentation at 3, 5 and 8 mm levels from the apex, to assess the canal transportation and centering ability. Results: The EdgeFile system produced the least canal transportation and remained more centered around the original canal than the other systems. While, PT system produced significantly the highest canal transportation and the least centered canal preparation than other systems. Conclusions: EdgeFile systems showed superior performance regarding maintenance of the original root canal curvature and centering ability than do other systems.

Purpose: This study was conducted to evaluate the biological pulp response to Pulpine and Polyamidoamine Dendrimer and their combination in dogs and comparing their remineralizing potentials on human caries affected dentin. Materials and Methods: Forty-five teeth in 3 mongrel dogs were randomly divided into 3 groups according to the applied pulp capping material; group A1: Pulpine NE, group A2: PAMAM G3 and group A3: Pulpine and PAMAM. Class V cavities were prepared; the pulps were mechanically exposed and finally restored with resin modified glass ionomer. Histological evaluation was performed after 2 weeks, 1 and 2 months. The in vivo study was designed as a randomized, unicenter, parallel, two arms, double– blind split mouth clinical trial with 1:1 allocation ratio. The subjects who fulfilled the eligibility criteria were asked to participate and signed informed consent. Twenty-eight adhesive occlusal cavities were prepared; infected dentin was removed leaving carious affected dentin at the pulpal floor and divided into 2 groups; P1 (Pulpine) and P2 (Pulpine and PAMAM). Remineralization was assessed radiographically at base line, 1, 3 and 6 months. Results: In the animal study, there was no statistically significant difference among the tested direct pulp capping materials regarding the inflammation intensity, dentin bridge continuity or morphology. For the clinical trial, P2 group showed statistically significant higher dentin density at all study intervals. Conclusion: Pulpine and PAMAM enhanced pulp tissue repair. PAMAM could induce biomimetic remineralization of caries affected dentin.

Purpose: This study was conducted to evaluate the effect of four different hard candies on salivary Streptococcus mutans count and change in salivary pH in a group of Egyptian college students. Materials and Methods: Forty-eight healthy dental students, aged 16 -22 years were randomly allocated into 4 different study groups each of 12 students: sucrose free hard candies with licorice extract group, sucrose free hard candies with xylitol extract group, sucrose free hard candies group, and sucrose containing hard candies group (control). Unstimulated saliva was collected from the participants at baseline, following which the participants were given respective hard candies twice daily for 10 days and the subsequent salivary samples were collected at intervals of 14 days and 6 months. The samples were analyzed for Streptococcus mutans count in terms of CFU and pH using pH meter. Results: Regarding baseline – 14 days interval, there was a statistically significant decrease in mean percentage change on bacterial count in licorice and xylitol group Moreover there was also a significant difference in salivary pH between different hard candies Conclusion: Addition of licorice or xylitol to sucrose free hard candies enhances its effect on streptococcus mutans and can shift salivary pH to a neutral value.

Purpose: To evaluate histopathologically the dental pulp response to bioactive glass nanoparticles in the resin composite restoration and the adhesive as a direct pulp capping material regarding inflammatory cell infiltrate, hard tissue formation and Pulp tissue disorganization. Material and methods: Four mongrel male dogs were selected for this study with a total of 40 teeth were divided into two groups (n=20) according to the treatment protocol (P); (P1) treated with light cured calcium hydroxide (control group) and (P2): treated with resin composite and its adhesive containing bioactive glass. The histopathological findings were studied for each specimen at two times intervals (T); (T1) fourteen days and (T2) sixty days. Split mouth technique was followed. The manufacturer’s instructions were followed during applying the materials. Animals were sacrificed at each time interval and teeth were collected for histopathological finding. Results: adhesive and resin composite restoration containing bioactive glass group showed significantly less inflammatory cell infiltrate, less pulp tissue disorganization and better calcific bridge formation than Calcium hydroxide group. When the effect of time was considered, inflammation was significantly decreased from fourteen days to sixty days while hard tissue formation was significantly increased for both materials. Also pulp tissue disorganization was decreased significantly and showed more normal pulp tissue morphology from fourteen days and to sixty days. Conclusion: resin composite restoration and its adhesive containing nanoparticles of bioactive glass could be used as a direct pulp capping material.

Purpose: To investigate the effect of Glycogen Synthase Kinase-3 (GSK3) antagonist on pulp tissue repair in rabbits. Materials and Methods: 24 adult healthy male rabbits were used in this study divided into three main groups: Group I (control): 2 rabbits with normal teeth without pulp exposure. Group II (TG): The exposed pulps of right posterior teeth of 22 rabbits were capped with KolSpon in association with 34 nM Tideglusib. Group III (MTA): The exposed pulps of left posterior teeth of 22 rabbits were capped with Mineral Trioxide Aggregate (MTA). The 2 rabbits with normal teeth and 6 rabbits with pulp capped posterior teeth were euthanized after one day. Their DNAs were extracted and tested for expression of Axin2 and β-actin by qPCR. 8 rabbits were euthanized after 4 weeks, and another 8 was euthanized after 6 weeks. The teeth were collected and prepared for immunohistochemical study using antiβ-catenin antibody. Results: The qPCR results showed the higher expression of Axin2 in the Tideglusib group than control group (without treatment) by about 5 folds and about 1.5 fold in the MTA group. The immunohistochemical results revealed the increase intensity in the Tideglusib group than MTA at four weeks with no significance difference (p>0.05).Whilst after 6 weeks the higher expression was in Tideglusib group with significance difference (p<0.05). Conclusion: The Tideglusib drug stimulates the expression of Axin2 transcription factor gene which is known to play a key role in regulation of odontoblast and osteoblast differentiation.
