ABSTRACT
Osteoporosis Is A Medical Condition Characterized By Low Bone Density And Micro-architectural Deterioration Of Bone. Antiresorptive Drugs And Estrogens Are Considered The Common Traditional Therapy For Post-menopausal Osteoporosis.

Aim: The Aim Of This Study Was To Evaluate The Action Of Red Clover And Chickpea On The Alterations Of The Mandibular Alveolar Bone And Periodontal Ligaments Induced By Ovariectomy In Albino Rats. Methods: 35 Adult Female Albino Rats Were Divided Into 5 Groups Each Of 7 Rats: The Negative Control Group (group I) That Were Only Subjected To Sham Operation And Did Not Receive Any Intervention, The Positive Control Group (group II) That Were Subjected To Ovariectomy Without Any Treatment, The Alendronate Sodium (bisphosphonate) Experimental Group (group III) That Were Subjected To Ovariectomy And Received Fosamax Daily For 3 Months One Month Postoperative, The Chickpea Experimental Group (group IV) That Were Subjected To Ovariectomy And Received Chickpea Extract Daily For 3 Months One Month Postoperative. And The Red Clover Experimental Group (group V) That Were Subjected To Ovariectomy And Received Red Clover Extract Daily For 3 Months One Month Postoperative. After Rats Were Terminated, Mandibular Molar Regions Were Excised And Stained For H&E Stain And Anti-fibronectin (FN) Immunohistochemical Stain. Specimens Were Also Examined For Bone Mineral Density (BMD).

Results: Histological And Immunohistochemical Examination Showed Inflammatory Reaction In Alveolar Bone And Oblique Fibers That Decreased Over The Course Of Treatment With Phytoestrogens. Statistical Results Showed That There Was No Significant Difference Between Phytoestrogens And Alendronate Sodium Drug (bisphosphonate) And There Was A Significant Difference Between Group II And All Experimental Treated Groups As Well As Between Group I And Experimental Treated Groups. Conclusion: Alternative Hormone Replacement Therapy Using Phytoestrogens Was Associated With Variable Grades Of Statistically Significant Reduction Of Osteoporosis And Periodontitis.

ABSTRACT
This Study Was Conducted To Evaluate The Effect Of Fiber Meshwork Reinforcement On The Fracture Of Maxillary Complete Dentures. Two Groups Of Dentures Were Fabricated. Five Dentures In Each Group. The First Group Had Conventional Non-reinforced Maxillary Complete Dentures. The Second Group Had Fiber-meshwork Reinforced Maxillary Complete Dentures. All Samples Were Individually Mounted On A Computer Controlled Materials Universal Testing Machine, Where Load Was Applied Bilaterally Using T-shaped Load Applicator. Initial Crack Load, Fracture Load And Fracture Pattern Were Recorded For Each Tested Denture. There Was No Statistical Significant Difference In Both Initial Crack And Fracture Loads Of Both Groups, On The Other Hand The Fracture Pattern Of The Fiber-meshwork Reinforced Group Was More Favorable And Less Extensive Compared To The Fracture Pattern Of The Non-reinforced Group. In The Clinical Situation, Both Conventional And Fiber-meshwork Reinforced Maxillary Complete Dentures Are Expected To Be Strong Enough To Resist Fracture Under Maximum Biting Forces, With The Fiber-meshwork Reinforced Dentures Having A More Favorable And Less Extensive Fracture Pattern Compared To The Conventional Non-reinforced Dentures.

ABSTRACT
Background: Forensic Odontology Is Described By The Federation Dentaire Internationale As ?that Branch Of Dentistry Which, In The Interest Of Justice, Deals With The Proper Handling And Examination Of Dental Evidence And The Proper Evaluation And Presentation Of Dental Findings?. This Study Aimed To Investigate And Analyze The Difference Between Egyptian Males And Females In Mandibular Indices? Measurements And Mental Foramen Position Using Cone Beam Computed Tomographic Images.

Materials and Methods: Thirty Six Patients Were Included In This Study. They Were Divided Equally Into Two Groups. The First Group Included Eighteen Females And The Second Group Included Eighteen Males. All Of The 36 Participants Were Scanned Using CBCT Scanner Then Six Indices Were Obtained From The Reformatted Panoramic Images Of Each Mandible (superior Index Of Mental Foramen Position, Inferior Index Of Mental Foramen Position, Mental Index, Gonial Angle, Antegonial Index And Ramus Height).

Results: It Was Found That There Was Statistical Significant Difference Between Males And Females Regarding Three Parameters Namely Superior Index Of Mental Foramen Position, Inferior Index Of Mental Foramen Position And Ramus Height However, There Was No Statistical Significant Difference Between Males And Females Regarding Three Parameters Namely Gonial Angle, Mental Index And Antegonial Index. Assessment Of Intra-observer And Inter-observer Reliability Regarding All Linear And Angular Measurements Showed Highly Significant Agreement Between Observers. Conclusion: Certain Mandibular Indices As: Superior Index Of Mental Foramen Position, Inferior Index Of Mental Foramen Position And Ramus Height Of Mandible Are Rendered As Reliable Gender Discriminators In Forensic Odontology. The Mean Values Of Males Are Higher Than Females Regarding The Superior Index Of Mental Foramen Position, Inferior Index Of Mental Foramen Position And Ramus Height. Certain Mandibular Indices As: Mental Index, Gonial Angle And Antegonial Index Are Rendered As Non-reliable Gender Discriminators In Forensic Odontology. Cone Beam Computed Tomography Is Considered As The Imaging Modality Of Choice To Assess The Role Of Mental Foramen Position And Mandibular Parameters In Gender Determination.
