Purpose : The purpose of this in-vivo study was to investigate the remineralizing effects of natural (propolis, hesperidin) versus synthetic agent (silver diamine fluoride with potassium iodide) after treatment of deep carious dentin at different time intervals. Materials and methods: Patients with deep carious class I lesions were selected according to inclusion and exclusion criteria. Class I carious lesions were randomly distributed into 4 groups according to treatment material: 1. Propolis, 2. Hesperidin, 3.Silver diamine fluoride with potassium iodide (SDF+KI), and 4. Control group (no treatment). Class I cavities were all prepared using step-wise caries removal technique. The treatment materials were then applied on the remaining carious dentin and restored with a glass ionomer (GIC) restoration. Assessment of remineralization was done by measurement of mineral-density of dentin using digital x-ray machine at baseline, 6-weeks and 12-weeks time intervals. Results: Silver diamine fluoride had a higher significant remineralizing effect than control, propolis or hesperidin. While propolis had a higher significant remineralizing effect than hesperidin. Conclusions: Both silver diamine fluoride and propolis agents have remarkable effect on remineralization of carious dental tissues.

Purpose: The purpose of this study was to evaluate the effect of diode laser-980nm on microhardness of young and old canal dentin after treatment with NaOCl, NaOCl/ EDTA and distilled water solutions. Material and Methods Forty-eight single rooted premolars were divided into three groups according to the chemical solutions used (16 each) (8 for young teeth <30 years old and 8 for old teeth >50 years old). Group I: irrigated with 5ml of 2.6% NaOCl activated with diode laser, group II: irrigated with 5ml of 2.6% NaOCl without laser activation followed by 5ml of 17% EDTA activated with diode laser and group III: irrigated with 5ml of distilled water activated with diode laser. Then microhardness was evaluated at coronal, middle, and apical thirds of each root canal. Results: In all young and old groups, the coronal third had the highest mean value, followed by the middle, and the apical third had the lowest mean value, with a statistically significant difference between thirds of the groups ( p 0.001<). There was a statistically significant difference between young and old teeth at all levels (coronal, middle, and apical) for each group (I, II, and III), with old teeth having a greater mean microhardness value than young teeth. Conclusion: Irradiation of NaOCl/EDTA solutions with 980-nm diode caused reduction in microhardness of young dentin more than old dentin, and NaOCl only or distilled water in all thirds of groups.

Purpose : The aim of the current study was to compare and contrast the effects of various smoking types. This study focused on traditional cigarettes, electronic cigarettes and heated tobacco products compared with non-smokers on the outcome of non-surgical treatment of moderate generalized periodontitis. Subjects and methods : The present study included a total of sixty (60) patients with moderate generalized chronic periodontitis. They were divided into four equivalent groups to be managed with non-surgical mechanical debridement. The clinical results of the study were evaluated using Plaque Index, Gingival Index, Pocket depth measurements, and Clinical attachment level. The clinical measurements were obtained at the baseline, 1 month, 3 months, and 6 months intervals. Samples of gingival crevicular fluid were collected from periodontal pockets at the site of periodontal treatment at the same intervals of clinical evaluation. The collected samples were analyzed for detection of interleukin 8 (IL8), and Tumor necrosis factor (TNF-α) levels. Results : Non-smoker group showed the best improvement of the clinical parameters and the lowest level of the inflammatory cytokines followed by the HTPs smokers then E-cigarette smokers’. Furthermore, traditional smokers showed the least improvement of the clinical parameters and highest level of the inflammatory cytokines. Conclusion : The present study revealed that different types of smoking affect the outcome of non-surgical periodontal therapy. Comparing between HTPs, vaping, and traditional smoking, HTPs have the least effect on periodontal therapy, vaping has the moderate effect and traditional smoking has the strongest effect.

Purpose: Diabetes mellitus (DM) has deleterious effect on various body organs es-pecially salivary glands. Therefore, this study was conducted to evaluate the therapeutic effect of curcumin on parotid salivary glands in diabetic rats. Material and methods: Fifty-six adult male albino rats weighting 150-200 g were selected and divided into two equal groups n= 28 rats each. Diabetes was induced in both groups I (Diabetic) & II (Diabetic & curcumin) with a single intraperitoneal injection of streptozotocin (STZ) at a dose of 55 mg/kg. After 2 weeks of diabetes confirmation; rats of group II received 200 mgkg of curcumin orally once daily. Both groups I and II were divided into 2 subgroups (A, B, C and D respectively) 14 rats each and were sacrificed after 15 and 20 days of curcumin administration, and the parotid glands sections were stained with Hematoxylin and Eosin, Anti-iNOS, and Anti-IL-2. Then were subjected to digital image analysis followed by two-way ANOVA statistical analysis. Results: Curcumin treated group revealed improvement in parotid glands in H&E sections es-pecially at 20 days when compared to diabetic group with reduced histomorphological alterations. While, immunohistochemically, curcumin treated group showed decreased expression in the levels of both iNOS and IL-2 with significant statistical difference with diabetic group in all time periods. Post hoc LSD test showed a significant difference between time periods of diabetic group while showed no significance between curcumin group. Conclusion: Curcumin can be possible candidate for hindering the regressive changes that affect salivary glands caused by diabetes.

Purpose: The aim of this study was to compare between the effects of using two different designs of extra coronal precision attachments on supporting structures of the abutment teeth in unilateral free end saddle partial denture. Material and Methods: Ten Kennedy class II partially edentulous patients with the last second premolar which is lasting abutment tooth were selected. The patients were divided into two groups (each group five patients), group I; patients were received unilateral partial denture retained by OT unilateral extra coronal attachment, group II; patients were received partial denture retained by OT cap extra coronal attachment with bilateral cross arch stabilization. Clinical evaluation including pocket depth measurements at four sides of last abutment tooth and radiographic evaluation using cone beam computed tomography (CBCT) was done at time of partial denture delivery, after 6, 9 and 12 months. Results: Inspection of radiographic evaluation revealed non-statistical significant difference between the two groups at the time of insertion, 6 and 9 months while after 12 months group II showed more bone loss than group I. Regarding the clinical evaluation showed non-statistical significant difference in pocket depth between two groups at time of insertion, 6 and 9 months and more pocket depth in group II at 12 months. Conclusions: Using special design of extra coronal castable precision attachment (OT unilateral) exerts less stresses on the abutments and their supporting structures in comparison with OT cap attachment, in addition to it is simple and more comfortable to the patients.

Purpose: to study the effect of different implant abutment sizes on fracture resistance of two ceramic monolithic crown systems. Material and Methods: Research Ethics committee approval of faculty of Dental Medicine for Girls was obtained (REC18-065). Forty (40) Titanium implant supported abutments were fabricated and divided into2 groups (n=20 each) according to abutment diameter; Group (1): implant abutment diameter 4mm and Group (2): implant supported abutment diameter 4.5mm. Samples of each group were divided into 2 sub-groups (n=10 each) according to type of monolithic ceramic crowns. Subgroup(A): zirconia ceramic crowns, Subgroup(B): vita suprinity crowns. All crowns were cemented to implant abutments by Rely X resin cement, then subjected to thermal cycling and seated on a universal testing machine and subjected to fracture resistance test. Data were statistically analyzed . Results: It was found that the highest mean ± SD values of fracture resistance were recorded for large diameter Zirconia subgroup (1032.2±174.78 N) followed by large diameter Vita suprinity subgroup mean ± SD values (935.7±83.71 N) then small diameter Zirconia subgroup (930.3±69.53 N), meanwhile the lowest mean ± SD values were recorded with small diameter Vita suprinity (815.9±101.52 N). Conclusion: The mean fracture values of zirconia were higher than that of vita suprinity crowns, while the crowns were supported on large implant abutment diameter had higher fracture resistance than that supported on smaller implant abutment diameter.
目的:研究不同种植基台尺寸对两种陶瓷全冠系统抗断裂性能的影响。材料和方法:获得女口腔医学院伦理委员会批准(REC18-065)。制作钛种植体支撑基牙40个，根据基牙直径分为2组，每组20个;组(1):种植体基台直径4mm;组(2):种植体支撑基台直径4.5mm。每组样本按整体瓷冠类型分为2个亚组，每组n=10。亚组(A):氧化锆陶瓷冠;亚组(B): vita superity冠。所有冠用Rely X树脂水泥与种植基台粘合，热循环后置于万能试验机上进行抗断裂测试。对数据进行统计学分析。结果:大直径Zirconia亚组的骨折阻力平均值±SD值最高(1032.2±174.78 N)，其次是大直径Vita超优亚组的平均值±SD值(935.7±83.71 N)，其次是小直径Zirconia亚组的平均值±SD值(930.3±69.53 N)，而小直径Vita超优亚组的平均值±SD值最低(815.9±101.52 N)。氧化锆牙冠的平均断裂值高于优质牙冠，而种植基牙直径大的牙冠比种植基牙直径小的牙冠具有更高的抗断裂能力。

Purpose: To evaluate the effect of different horizontal condylar guidance registration methods and articulators on bilateral balanced occlusion of complete denture. Materials and Methods: Twelve completely edentulous patients with ages ranging from 50-60 years old were selected from the outpatient clinics of the Removable Prosthodontic Department, Faculty of Dental Medicine for Girls, Al-Azhar University. Twelve complete dentures were constructed according to the balanced occlusal concept and then duplicated for experimental work. Horizontal condylar guidance angles were measured using three different methods; the protrusive interocclusal wax record method, tracing method, and Cone Beam Computed Tomography (CBCT) scan. The angles were adjusted on two types of articulators; Arcon and non-Arcon articulators. The effect of each method and the effect of the two types of articulators on bilateral balanced occlusion were studied. Results: The result of this study showed that there was no significant difference in bilateral balanced occlusion when using different types of articulators or different horizontal condylar guidance registration methods during the construction of complete denture. Conclusion: Within the limitation of this study, it can be concluded that the Hanau system with the wax protrusive record may be the most practical way to obtain the desired relative horizontal condylar angle.
