Materials and methods: In this study 18 posterior teeth in 9 New Zealand white rabbits were involved and simple randomization design was used. All of the experimental teeth were subjected to direct pulp capping procedures. Eighteen teeth were divided into 3 groups, each one consisted of 6 teeth. In group I, calcium hydroxide (CH) was used, while TDMP and TDM powder impregnated with BMMSCs were used in group II and group III respectively. Modified glass ionomer was used as a sealing restoration. After four weeks, animals were euthanized and experimental teeth were demineralized and processed for histological examination to see if a hard tissue barrier was formed. Results: TDMP presented the best results where a continuous reparative dentin bridge with homogenous tubular structure was formed. On the other hand, CH stimulated the formation of non-continuous irregular hard tissue masses while seeding BMMSCs on TDM powder resulted in defect closure with a bone like material and dentin like islands were formed inside the adjacent pulp. Conclusion: pulp capping with TDMP without adding stem cells from other sources like bone marrow is more effective in producing a high quality dentin bridge through its effect in stimulating the resident cells inside the pulp < /p>https://adjg.journals.ekb.eg/article_294755_fe5d96156dffd367f88f35e207428794.pdfAl-Azhar University, Faculty of Dental Medicine, Girls BranchAl-Azhar Dental Journal for Girls2537-030810120230101Evaluation of the Effect of Hyaluronic Acid Gel Loaded with Simvastatin on the Osseointegration and Stability of the Dental Implants39340029477210.21608/adjg.2023.101955.1421ENWesam S.IbrahimOral and Maxillofacial Resident at Al-ahrar Teaching Hospital, Zagazig , Egypt0000-0001-6602-3246Fatma I.MohammedProfessor of Oral and Maxillofacial Surgery Department, Faculty of Dental Medicine for Girls, Al-Azhar University, Cairo,

Subjects and methods: Twelve implants were inserted in mandibular posterior edentulous region that required rehabilitation with fixed implant-supported prosthesis were included in this study. The patients were divided into 2 groups: Group A; the edentulous sites were treated by 6 implants which were inserted with the application of Hyaluronic acid (HA) gel loaded with Simvastatin (SMV) in the drilling site. Group B; Six dental implants were placed in edentulous sites without the use of HA gel containing SMV. The clinical follow-up was done at three and six months, whereas the radiographic follow-up was done at three and twelve months. Treatment changes were evaluated for each group and a comparison was done between the 2 groups. Data were analyzed to assess difference and association of qualitative variable by Chi square test (X2 ), paired by sign test and Differences between quantitative independent groups by paired t test. Results: Radiographically; at 3 and 12 months, there was a statistically significant difference in bone density between two groups. While, there was no statistically significant difference in implant stability between two groups immediately and after 3months.Conclusion: Application of HA gel loaded with SMV around dental implant improves the implant stability and bone density around the implant which enhances the osseointegration of implant.https://adjg.journals.ekb.eg/article_294772_5459651eac29ba7f31f129f4f88ea5ef.pdfAl-Azhar University, Faculty of Dental Medicine, Girls BranchAl-Azhar Dental Journal for Girls2537-030810120230101Evaluation of Controlled Release Simvastatin around Dental Implant in Controlled Type II Diabetic Patient40141129484710.21608/adjg.2023.103233.1429ENSalma M.BaheirDentist at Medical Administration Center, Al-Azhar University, Cairo, EgyptMai S.AttiaProfessor of Oral Medicine, Periodontology, Oral Diagnosis and Radiology, Faculty of Dental Medicine for Girls Al-Azhar

Subjects and methods: 100 Subjects were divided equally into five groups with reference to new classification of periodontitis. Clinical parameters including probing pocket depth (PPD), clinical attachment level (CAL) gingival index (GI) and plaque index (PI) were measured. Samples of subgingival plaque were taken for microbiological analysis and bacterial DNA extraction. Bacterial identification was done using polymerase chain reaction (PCR) for 5 bacteria (Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Treponemadenticola (Td), Tannerellaforsythia (Tf), Fusobacterium nucleatum (Fn) in all samples for the study population. Results: The mean plaque index, gingival index, PD, and CAL were calculated, and the prevalence of P.g, T.d, T. f,A.a and F.n was also identified. Conclusion: for all kinds of bacteria the mean of real time increased by increasing the stage number. The difference between the healthy group and all stages was statistically significant. We can arrange the bacteria sequence as follows based on the overall mean of real time PCR for each type of bacteria: T.f,P.g, T.d,F.n,A.a. It was also clear that the relationship between PD and CAL and other bacterial microbiota was statistically significant.https://adjg.journals.ekb.eg/article_294858_1f471c312741204da8c9326e5a27b1b5.pdfAl-Azhar University, Faculty of Dental Medicine, Girls BranchAl-Azhar Dental Journal for Girls2537-030810120230101Molecular Assessment of Kallikrein 3 in Ameloblastoma and Odontogenic Keratocyst11312128189710.21608/adjg.2022.73151.1353ENKholoud R.AhmedOral pathology, faculty of dentistry, Ahram candian university, 6th of October city, EgyptMohamedEl SebieLecturer of medical biochemistry, Faculty of Medicine, Cairo University, Cairo, Egypt.NadiaRadiAssociate Professor of Oral and Dental Medicine for Girls, Al-Azhar University, Cairo, Egypt.Amal H.Abd El RahmanProfessor of Oral and Maxillofacial Pathology, Faculty of Dentistry, Cairo University, Cairo, EgyptEman A.AboHagerProfessor and Head of Oral and Dental pathology Department Faculty of Dental Medicine for Girls, Al-Azhar University,

Material and methods: 30 paraffin embedded blocks of AB, OKC and Dentigerous Cyst (DC) as a control were included. Immunohistochemical staining technique with KLK3 antibody was applied to all the tissue blocks and RT-PCR KLK3 gene were done for all specimens. Results: The mean area percent of KLK3 expression was significantly greater in AB and OKC compared with DC. According to the current study, presence of significant difference between AB and OKC in relation to control indicates that KLK3 antibody is related the aggressive biologic behaviour of AB and OKC. Conclusion: Increased expression of KLK3 protein and gene expression in AB and OKC suggests that KLK3 may have a role in the intrinsic and limitless growth potential of these lesions.https://adjg.journals.ekb.eg/article_281897_5685b47ede4bb1986b0f37b696087f70.pdfAl-Azhar University, Faculty of Dental Medicine, Girls BranchAl-Azhar Dental Journal for Girls2537-030810120230101The Effect of Human Demineralized Dentin Matrix Scaffold Alone and Combined with Concentrated Growth Factor on Bone Repair in Rabbits12313028189510.21608/adjg.2022.73763.1357ENSomayaMostafaAssistant Lecturer at Oral and Dental Biology Department, Faculty of Dental Medicine, Al-Azhar University, Cairo, Egypt.Mena F.Abd AllahLecturer at Oral and Dental Biology Department, Faculty of Dental Medicine, Al-Azhar University, Cairo, EgyptHeba A.AdawyProfessor and Head of Dental Biology Department, Faculty of Dental Medicine, Al-Azhar University, Cairo, Egypt.Journal Article20210524Purpose: This study aimed to evaluate the potential effect of Human Demineralized Dentin Scaffold (HDDS) alone and when combined with Concentrated Growth Factor (CGF) on repair of bony defects in the tibia of rabbits, histologically, by using scanning electron microscope and computed tomography. Materials and Methods: Ten adult male rabbits (weight 2 to 2.5 kg) were used in this study. Ethics committee approval of Faculty of Dental Medicine For Girls as obtained with code number (REC-BI-19-01). In each rabbit two holes were created (one in each tibia). In five rabbits, the first control hole was left empty and the second was packed with CGF. In the other five rabbits, one hole was packed with DDM slices from anonymous human permanent teeth without carious lesion or other pathology and the second was packed with DDM and CGF. The rabbits were euthanized at 1 and 6 weeks postoperatively and the bone samples were processed for histological analysis. Results: Faster bone repair was occurred in the experimental groups. In all groups, Osteoid tissue formation was occurred at one week, and osseous tissue formation was seen filling the bone defects at 6 weeks. The best results after 6 weeks appeared in surgical bone defects grafted with HDDS and CGF where the new bone showed better organization than the HDDS alone and CGF alone and most of the formed osteons were fully compacted. Conclusion: Combining Human Demineralized Dentin Scaffold (HDDS) with concentrated growth factor (CGF) improved graft biomaterial when used as xenograft and it became more effective through inducing a faster bone repair.https://adjg.journals.ekb.eg/article_281895_47cc0ec77bcf944a3826f1573597eb7c.pdfAl-Azhar University, Faculty of Dental Medicine, Girls BranchAl-Azhar Dental Journal for Girls2537-030810120230101Correction of Gummy Smile by Surgical Lip Repositioning with Myotomy versus Botox Injection Technique13113728188610.21608/adjg.2022.76210.1383ENKarima M.AliMaster Degree in periodontology Cairo University, Cairo, Egypt.NaglaaEl-KilanniProfessor and Head of Oral Medicine, Periodontology Department Faculty of Dental Medicine for Girls, Al-Azhar

Subjects and Methods: A sample of 10 female patients with age range (19-42) yearold with excessive gingival display greater than 2 mm were randomly allocated into 2 groups, Group I: patients were treated with surgical lip repositioning with myotomy. Group II: patients were treated with Botox injection. Treatment changes were evaluated for each group and compared between groups. Data were collected and analyzed using paired t-test for each group and student t-test to compare between groups at baseline, 3, 6 and 9 months. Results: Results of intragroup comparisons of gingival display revealed a significant difference between values at 3, 6 and 9 month intervals (p < 0.001). When compared at baseline, 6 and 9 months time points, the results at 3 months were better. Both groups showed deterioration of the outcomes obtained over time. Botox group values in gingival display had returned to base line at 9 months in contrast to surgical repositioning suggesting that the surgical lip repositioning combined with myotomy resulted in a more stable outcome. The amount of post-operative pain measured in Botox injection group (0.60±0.89) was significantly lower than that of surgical lip repositioning group (5.40±1.14) (p < 0.001). Conclusion: surgical lip repositioning with myotomy and Botox injection give satisfactory results in gummy smile patients in terms of reducing gingival display. However, surgical lip repositioning has more stable results for more than 9 months.https://adjg.journals.ekb.eg/article_281886_8a75a7ea33d332721631fec10683736b.pdfAl-Azhar University, Faculty of Dental Medicine, Girls BranchAl-Azhar Dental Journal for Girls2537-030810120230101The Effect of Psychological Stress on Periodontal Disease during COVID-19 Virus Threat: Relation to Salivary Prostaglandin (PGE2)13915028188110.21608/adjg.2022.95954.1408ENSamah M.HelmyDentist at Al -Azhar medical administration Girls branch.Hamdy A.NassarProfessor of Oral medicine, periodontology, Oral Diagnosis and Radiology Faculty of Dentistry for Girls, Al-Azhar University, Cairo, Egypt.Omnia E.AhmedLecturer of Oral medicine, periodontology, Oral Diagnosis and Radiology Faculty Dentistry for Girls, Al Azhar University,

Materials and methods: A total of 30 participants who had particularly high scores on the perceived stress scale (PSS) were involved in this study. Psychological stress was assessed via the PSS questionnaire. The Clinical periodontal evaluation included assessment of gingival index (GI), probing depth (PD) and clinical attachment level (CAL). Biochemical quantification of serum cortisol concentrations and S-IgA levels was performed using the enzyme-linked immunosorbent assays method (ELIZA). Every step was performed at the baseline during the lockdown, 3 and 6 months follow up after lockdown. Results: An increase in stress levels was detected over the course of the study and was statistically significant. Clinically, worsening of GI, PD and CAL records was observed over the follow-ups, yet this increase is non-significant for all indices (P>0.05). The correlation between serum cortisol and stress was positive and statistically significant over the three pickups (P<0.05). A weak negative correlation between stress and S-IgA was reported and wasn’t statistically significant. Conclusion: The impact of stress caused by lockdown and fear of pandemic was a continuous process where the time factor was very crucial in this study. High cortisol levels as a stress response and consequently S-IgA diminution were associated with worsening of the periodontal condition. Prolonged periods of stress may have an exaggerated impact on the periodontal condition of the subjects.https://adjg.journals.ekb.eg/article_281878_7972458a2f3d2f23dbba7f865228faff.pdf
