Abstract: Aims : The aim of the current study was to evaluate dentists and patients choices of type of restorative materials applied in fillings and their knowledge about the mercury content in amalgam restorations. Methods: a cross sectional descriptive study based on two types of questionnaire, one for the dentists(119) and the other specific for the patients (500) were distributed to determine the knowledge and awareness, preference of amalgam and composite restorations. Results: showed that the of awareness of the dentists about the amalgam controversy came from different sources, half of the dentists sample stated amalgam restorations were safe, were as 21% stated it unsafe. Placement of the selected restoration(either type) was influenced by different factors, recall appointments of patients complaining from several complaint was mostly from composite. For patients 67.6 % didn’t have any knowledge about harmful effect of mercury release from amalgam with the majority of the patients stating that they preferred composite or a tooth colored restoration. Conclusion: with in the limitations of this study awareness of safety of dental amalgam among the dentists was low, with a large agreement that postoperative complications were mainly due to composite restorations. For the patients the majority did not know anything about issues related to the mercury content of the amalgam and majority of them favored the placement of composite restoration similar to the color of their teeth.

Abstract: The purposes of the suggested research are to assess the effectiveness of different protocols in decreasing oedema and aching post extraction of third wisdom teeth. Materials and Methods: The research involved thirty patients whom had impacted mandibular wisdom teeth of different local anatomical locations. Kinesiology adhesive tape put for one week only for 15 cases and Dexamethasone 8 mg submucosaly injected directly post operatively for other 15 cases. swelling was calculated by a tape scale means from known points and mean taken also pain evaluated by VAS using ribbon gauge degreed from 1 to 10. Calculations had been applied for the first day of surgical intervention, 3rd day and seventh day. Results: There was no significant statistical differences were documented statistically for oedema readings concerning two study methods on the reading day one, three and seven following the operation, and there were highly significant readings related to pain parameters. Conclusions: Usage of Kinesiology adhesive tape clinically was closely with a same advantageousness with Dexamethasone injection submucosaly in dropping the oedema and pain parameter, although clinically dexamethasone was better in both parameters than Kinesiology tape, so it can be used additionally in contraindicated cases of prescribing steroids for alleviating ache, oedema following to wisdom teeth surgery.

Abstract: Abstract Objectives: direct the surgeons to solve the problem of insufficient posterior alveolar ridge height for successful dental implants.Materials and Methods: Case series: Four patients underwent inferior alveolar nerve translocation operation with dental implant, One male and 3 females. Intervention and outcome: Cases divided to 2 groups, group A in which surgery done under local anesthesia were the bony windows not involve the mental nerve (the window done distal to mental nerve). Group B underwent surgery under general anesthesia with bony window involve mental nerve. Result: Survival rate of the I.A.N. were 100% with 9 succeed dental implants inserted with the translocation of the nerve. Fixed prosthesis delivered with good satisfaction of these patients. Parasthesia extend between 3 weeks up to 8 weeks with complete recovery after 6 months. Patients followed for 6 years. Conclusion: IAN Lateralization and Transposition is the most appropriate choice for dental fixture replacement in atrophied posterior mandible rather than other choices as bone augmentation or short implants. Although skill, precise and experience challenges must available in the surgeon for optimal and long term success result. Avoidance of permanent injury to the IAN should be avoided by accurate clinical and radiographical examination. Patient choice for local or general anesthesia has no effect on surgeries itself.

Abstract: Aims : This study aimed to investigate the histopathological effect of cytarabine drug on liver and buccal mucosa in mice. Materials and Methods: Sixteen male albino mice were randomly assigned to two experimental groups and housed as eight animals /cage as a group.Control Group: was given daily I.P distilled water   for 5 days. Cytarabine Group: was given daily Cytarabine at dose (100mg/kg/ I.P) for 5 days. At the end of experiment, all animals were sacrificed and liver in addition to the  buccal mucosa were excised and placed in 10%  buffered formalin solution for histological preparation and evaluation. Results: histopathological study of cytarabine treatment group showed multiple changes in liver like defused vacuolar swelling with abnormal hepatic cords patterns, congested sinusoids and multiple foci of apoptotic cells while in buccal mucosa sections revealed a severely shrinkaged and atrophied appearance of mucus-salivary glands, vacuolation of the stratified squamous epithelium and interstitial edema.

Abstract: Aims: The aim of the current study is to compare the impact of using different drilling protocols on the dental implants primary stability inserted in the low-density bones. Materials and Methods: Out of twenty-two, ten oxen ribs were used in this in-vitro study. Using computed tomography (CT) scan, the most proximal three centimeters (cm) of the rib was confirmed to be a low-density bone comparable to human edentulous jaw bones. Forty dental implants were inserted, each rib received four dental implants using four different techniques that are arranged into four study groups:Group (I): includes a number of ten dental implants where the drilling burs and implants have the same size. Fit-size technique (F.G).Group (II): includes a number of ten dental implants where the diameter of the drilling burs is less than the implant diameter. Under-sized technique (U.G) Group (III): includes a number of ten dental implants where the simplified drilling protocol (Drill bypass) (D.G) was used for insertion.Group (IV): includes a number of ten dental implants where combined drilling protocols (C.G) (Undersized U.G+ Drill bypass D.G) were used for insertion. Results: Results revealed a statistically significant difference in the mean of insertion torque values (IT) between combined group (C.G) (65.000 N.cm) and fit-sized group (F.G) (45.0000 N.cm).Concerning Periotest M, a statistically significant difference was found in the mean of (PTV) between combined group (C.G) (-6.4500) and fit-sized group. A statistically highly significant correlation was found between insertion torque values (ITs) and Periotest M values (PTVs). Conclusion: Dental implant insertion in low-density bones using simplified drilling protocol (Drill bypass) (D.G) is better to be combined with undersized implant bed preparation (U.G) to enhance implant primary stability and with less time.Keywords: Kinesiology adhesive tape, Swelling, Pain, Dexamethasone, lower third molar teeth removal.
