ABSTRACT
The Lack Of The Normal Values Of Physiologic Tooth Mobility For Healthy Maxillary Permanent Central Incisors With Closed Apex For Children In The Egyptian Population Urged The Need To Conduct This Study. The Periotest M Device Was Used Because Of Its So Many Merits As The Reliability& Unbiased Results. It Was The Latest Wireless Device That Was User Friendly & Could Be Easily Accepted By The Children. The Total Sample Size Was 377 Children (164 Males & 213 Females) In The Pre Pubertal Period (9-13 Years Old) To Exclude The Hormonal Influence On The Readings. The Upper 2 Central Incisors For Each Child Were Tested, Giving A Total Of 754 Teeth Tested In This Study. These Values Can Be Extremely Beneficial In Early Diagnosis Of Certain Diseases Or Problems Of The Periodontium In Pediatric Dentistry. In Traumatic Dental Injuries, Using The Periotest Can Help In Monitoring The Progress Of The Treatment Of Traumatized Teeth & The Duration Of The Splint. In Addition This Could Allow The Operators To Be More Certain About The Line Of Treatment Offered To The Traumatized Teeth. The Study Was Able To Find The Numbers To Answer The Aim Of The Study. The Results Showed That Gender Affected The Scores Of The Periotest Significantly At The Age 12.5 Years In The Studied Sample. There Was A Negative Significant Correlation Between Age And Average Periotest Reading For Males & An Insignificant Correlation Between Age And Average Periotest Reading For Females In The Studied Sample.

ABSTRACT
The Purpose Of This Randomized, Double-blind, Controlled Study Was To Assess The Effect Of Antibiotic Premedication On Pre Treatment And Post Opertive Pain After Endodontic Treatment. Forty Two Patients With Symptomatic Irreversible Pulpitis Were Randomized And Allocated To Experimental And Placebo Groups Where The Experimental Group Received The Antibiotic Premedication. Degree Of Pain Was Measured By The Number Of Analgesics Needed In Addition To A Four Step Pain Scale Before Initiation Of Endodontic Treatment And At Time Intervals Of 6, 12, 24, 48 And 96 Hours. We Found That No Statistical Significant Difference Was Detected At The Pretreatment Time Interval. Statistical Significant Difference Was Groups After 24 Hours Of Endodontic Treatment Where The Experimental Group Reported Less Degree Of Post Operative Pain Than The Placebo Group. No Statistical Significance Difference Detected At Other Time Intervals. We Concluded That Antibiotic Premedication Could Be Prescribed To Lessen The Degree Of Post Operative Pain After Endodontic Treatment.

ABSTRACT

Objectives: To Evaluate The Effect Of Using Two Different Voxel Sizes (0.4mm And 0.2mm) On The Accuracy Of Cone Beam Computed Tomography In The Detection Of Simulated Mandibular Condylar Erosions.

Materials and Methods: Twelve Dry Human Mandibles (24 Condyles) Were Selected And Simulated Erosions Were Drilled On The Five Condylar Surfaces (superior, Anterior, Posterior, Medial And Lateral Surfaces). The Mandibles Were Scanned With PlanmecaPromax 3D Mid CBCT Machine Usingnormal And High Resolution Protocols (voxel Sizes: 0.4mm And 0.2mm Respectively).

Results: Regardingthe CBCT Normal Resolution Protocol(voxel Sizes: 0.4mm) The Sensitivity Of Detection Of The Simulated Defects Ranged From 87.05% To 94.96% And The Accuracy Values From 88.9% To 95.86% Among The Observers. However, Higher Values Were Found With The High Resolution Protocol (voxel Sizes: 0.2mm) Where The Sensitivity Values Increased To The Range Of 93.53% To 97.84% And Also Did The Accuracy Values With Range Of 94.44% To 98.15%.The Percentage Agreement Between Both Protocols Were 97.53% And 93.21% For The Two Observers. Conclusion: Despite The Higher Sensitivity And Diagnostic Accuracy Values Of The CBCTsmaller Voxel Size Protocol, Both Protocols Were Comparable In The Detection Of The Simulated Mandibular Condylar Erosions.

ABSTRACT
The Mesio-distal Crown Diameter Of Teeth Is An Important Factor Which Affects The Alignment Of Teeth In The Bony Arches And The Development Of Occlusion During Transition Of The Dentition. This Study Was Concerned With The Mesio-distal Width And Dental Arch Dimensions In Egyptian Children In Rural Areas Of Al Giza Governorate Which Will Be Helpful To Overcome Obstacles Which May Be Faced In Different Fields Of Dentistry (orthodontics, Pedodontics, Prosthodontics And Oral Surgery).
Objectives: Determine The Combined Mesio-distal Width Of The Permanent Mandibular Incisors And That Of The Maxillary And Mandibular Canines And Premolars In A Group Of Egyptian Children In Rural Areas Of Al Giza Governorate. And To Find The Correct Relationship Of The Total Mesiodistal Widths Of Teeth Under Study. Methods: A Sample Of 280 Egyptian Childeren With An Age Range From 12-15 Years Attending Schools In Rural Areas Of Al Giza Governorate. The Children Were Referred From These Schools (Almansorya, Berkash, Nekla And Abdelsamad?s) To The Local Medical Health Unit In Al Giza Governorate To Be Examined.

Results: In This Study The Results Showed That The Teeth Size Of Male Subjects Was Slightly Larger Than That Of The Female Subjects. There Was No Statistical Significant Difference In The Mean Of Mesiodistal Tooth Width Between Right And Left Sides For Almost All Teeth Under Study. And A Positive Correlation Exists Between The Sum Of The Mesiodistal Width Of Upper Right Canine And Premolars & The Sum Of The Mesiodistal Width Of The Lower Incisors Among Both Genders Combined. Conclusion: The Mesiodistal Width Of Upper And Lower Canines And Premolars Can Be Predicted By Measuring The Mesiodistal Width Of Lower Incisors, Clinicians Can Rely On The Meisodistal Tooth Width Of One Side If The Contra Lateral Was Missing And Separate Data Regarding Sex While Treating Egyptian Children Has To Be Used.

ABSTRACT
Background: Pedicle Flap Design Is Reported To Enhance Wound Healing And Decrease Incidence Of Dry Socket. However, Limited Data Are Available In The Literature About Its Effect Following The Removal Of Impacted Mandibular Third Molar.

Purpose: To Compare The Post-operative Complications Of The Traditional Triangular Flap And The Pedicle Flap After Surgical Extraction Of Mandibular Third Molars.

Materials and Methods: This Study Was Conducted On Forty Impactions Presented In Twenty Patients With Bilateral Impacted Mandibular Third Molars, Divided Into Two Equal Groups; Group A: The Study Group, In Which Pedicle Flap Design Was Performed And Group B: The Control Group, In Which Triangular Flap Was Performed. Postoperative Pain Was Evaluated Using Visual Analogue Scale (VAS) On 2nd And 7th Postoperative Days, Swelling Was Evaluated On 2nd And 7th Day Postoperatively Using Tape For Measurement Of Two Facial Dimensions, Trismus On 2nd And 7th Days Postoperatively By Using Digital Vernier Was Evaluated Calipers, Wound Dehiscence And Dry Socket Were Evaluated On 2nd And 7th Postoperative Day. Result: There Was No Significant Difference Between The Two Flap Designs Regarding Postoperative Swelling, Trismus And Pain. The Wound Dehiscence Was Lower In The Pedicle Flap Group Compared To The Triangular Flap Group As Recorded In Second Day (P<0.001) And Seventh Day (P=0. 01). The Dry Socket Was Lower In The Pedicle Flap Group Compared To The Triangular Flap Group As Recorded In Second Day(P=0.047) While No Statistical Significance Difference Between Both Groups In The Seventh Day (P=0. 102). Conclusion: There Is No Significant Difference Between The Pedicle Flap Design And The Triangular Flap Regarding Postoperative Pain, Trismus And Swelling After Impacted Third Molar Surgery. However, This Study Reported That Pedicle Flap Design Had Lower Incidence Of Wound Dehiscence And Dry Socket.

ABSTRACT
The Aim Of This Randomized Clinical Trial Was To Evaluate The Retention Of Single Implant Mandibular Over-dentures Retained By Locator And Ball Attachments. 14 Completely Edentulous Patients Were Included In The Study. They Received Single Midline Implants To Support A Mandibular Over-denture. Implants Were Allowed To Osseo-integrate For 12 Weeks. Patients Were Randomized Into 2 Equal Groups; Six Patients In Each One. Group I Received A Ball Attachment While Group II Received Locator. Retention Was Measured Using A Force Meter At Day Of Pick Up, 1 Month, 3 Months And 6 Months. Group II Locator Showed Higher Initial Retentive Force With A Mean Of (380.25 Gm. �258.19) Than Group I Ball With An Initial Retention Of (229.71 Gm. � 73.42). The Retention Of Both Attachments Decreased With Time Was No Statistically Significant Difference In Percentage Of Change In Retention Between Them. However, The Locator Remained More Retentive At The End Of The Follow-up Period Of 6 Months. As A Conclusion, The Locator Showed Higher Retentive Values For The Single Implant Over-denture Hen Compared To The Ball Attachment.

ABSTRACT


Introduction: Zygomaticomaxillary Complex (ZMC) Fractures Are One Of The Most Frequent Injuries To The Facial Skeleton Due To Its Position And Facial Contour. Although A Great Volume Of Literature Exists On Treatment Of These Injuries, There Is No Consensus. Computed Tomography; Being The Gold Standard For Evaluation Of Maxillofacial Fractures, Is An Indispensable Modality For Diagnosis And Evaluation Of The Fractures Both Pre- And Post-operatively. This Prospective Study Presents An Investigation Of The Quality Of Reduction Of ZMC Fractures Using Multi-detector Computed Tomography (MDCT). Patients And Methods: Fracture Reduction Quality Was Assessed By Comparing Between Pre- And Post-operative Radiographs Using MDCT. Other Variables Examined Included The Demographics, Etiology, And Treatment Modalities. Data Were Collected From Four Egyptian Hospitals, During The Year 2016.

Results: A Total Of 30 Patients Were Presented In Our Study, During The Year 2016. The Higher Incidence Was In Males At Their 2nd Decade Of Life. Road Traffic Accidents Was The Most Common Cause Of Injuries. Fixation Of The Fractured ZMC Was Mainly Achieved Through Open Reduction And Rigid Internal Fixation. As For The Pre- And Post-operative Radiographic Analysis; A Total Of 20 Fractures Were Considered Acceptably Reduced, While An Equal Amount Of Fractures Was Considered Sub-optimally Reduced. Conclusion: ZMC Fractures Are A Common Injury In Young Males Following Road Traffic Accidents In Egypt. Radiographic Analysis Using Multi-detector Computed Tomography Can Accurately Determine Quality Of Fracture Reduction And Drastically Improve Treatment Outcome.

ABSTRACT


Introduction: The Zygomaticomaxillary Complex (ZMC) Is Essential In Defining Facial Aesthetics Due To Its Prominence And Convex Shape. It Also Serves As Major Functional Buttress Of The Face. The Paired Zygomas Are Two Cornerstones That Are Of Surgical Importance In Restoring Lost Orbital Volume And They Serve As References In Midface Fractures Reduction. Primary Goals Are Both Restoration Of Facial Projection & Symmetry And Restoration Of Orbital Volume & Globe Position. Management, However, May Range From Observation To Extensive Reconstruction Of The Zygoma, Orbital Frame, Orbital Floor, And Zygomatic Arch. This Prospective Study Presents An Analysis Of ZMC Fractures Reduction Quality Through Post-operative Clinical Evaluation And Patient Satisfaction From The Overall Treatment Outcome. Patients And Methods: ZMC Fractures Reduction Quality Was Assessed By Analyzing Data From Post-operative Clinical Evaluation As Well As Comparing And Contrasting This Data With The Patients? Satisfaction From The Final Outcome Of Treatment. Other Variables Examined Included The Demographics, Etiology, Radiographic Analysis, And Treatment Modalities. Data Were Collected From Four Egyptian Hospitals, During The Year 2016.

Results: A Total Of 30 Patients Were Presented In Our Study, During The Year 2016. Several Post-operative Clinical Parameters Were Evaluated To Assess The Treatment Quality; The Most Common Finding Was Palpation Of ZMC Articulation Which Occurred In 14 Patients, Followed By Abnormal Ocular Movement Which Occurred In 10 Patients. Post-operative Trismus Was Seen In 10 Patients, Whereas Facial Asymmetry Affected 7 Patients. Comparing The Patient Satisfaction Score By Time, A Gradual Increase In Score Was Noted In Both Unilateral And Bilateral Cases. Conclusion: The Diversity Of Injury Patterns In The Maxillofacial Region Makes Each Fracture Unique, Which Adds Difficulty To The Surgeons In Always Reaching A Standard Outcome. One Parameter Or Even More Are Sometimes Inconclusive To Evaluate The Outcome Of Trauma Treatment.
