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.

ABSTRACT
Visible Head And Neck Skin Scars Have A Negative Psychological Impact On Patients, Thus Many Trials Were Achieved To Minimize It. The Aim Of The Present Study Was To Compare Between The Effect Of Botulinum Toxin Type A (BTA) And Silicone Gel Patch On Scar Formation. Twelve Patients With Condylar And/or Angle Fracture Were Treated By Open Reduction And Internal Fixation Through Retro-mandibular Incisions. They Divided Randomly Into Two Groups. Group A Received Botulinum Toxin Type A (BTA) Injection While Group B Were Treated With Silicone Gel Patch. Nine Patients Completed The Trial. According To OPSAS, VSS And VAS, The Difference Between The Two Groups At One Month, And Six Months Was Statistically Insignificant, Meanwhile, There Was A Statistically Significant Difference In The Improvement Of The Scar Appearance That Treated By Either BTA Or Silicone Patch. According To This Study, We Concluded That BTA And Silicone Patch Has The Same Effect On Prevention Of Scar Formation.

ABSTRACT
Objective: This Study Aimed To Assess The Accuracy Of Linear Measurements Achieved Using Planmeca Promax 3D MID? CBCT Scanner In Both Standard And Different Head Positions.

Materials and Methods: Eleven Dry Human Skulls Were Selected Where Gutta Percha Markers Were Located To Define 3 Dimensions (occluso-apical, Bucco-lingual And Mesio-distal Dimensions) In 5 Regions For Each Jaw: Anterior, Bilateral Premolar And Bilateral Molar. Real Measurements Were Taken Using A Digital Caliper. Then, The Skulls Were Imaged In Standard And Four Accurately Adjusted Different Head Positions (forward Tilt, Backward Tilt, Lateral Tilt And Rotation). Linear Measurements Were Performed On CBCT Images By Two Radiologists Separately And Independently.

Results: Statistical Analyses Revealed Excellent Inter And Intra Observer Agreement Between The Linear Measurements Performed By Both Observers On CBCT Images In Each Skull Position And Moreover, An Excellent Agreement Of These Measurements And The Real Measurements. The Absolute Measurement Error Did Not Exceed 0.52 Mm In All The Study Regions Of All The Skull Positions, And No Statistically Significant Difference Was Found Between This Error In All CBCT Linear Measurement Performed In Any Skull Position. Conclusion: Within The Limitations Of The Current Study, Linear Measurements Performed Using Planmeca Promax 3D MID? Are Accurate And Reliable, And Their Accuracy Is Not Influenced By Minor Changes In The Patient?s Head Position.

ABSTRACT
Objective: The Purpose Of The Present Study Was To Assess Anesthetic Efficacy Of 4% Articaine Infiltration Versus 2% Lidocaine Nerve Block After Premedication By Ibuprofen In Endodontic Treatment Of Acute Irreversible Pulpitis In A Randomized Clinical Trial (RCT). Participants And Methods: Fifty-two Emergency Patients Diagnosed With Symptomatic Irreversible Pulpitis In Mandibular First Molar, Were Equally And Randomly Divided In Lidocaine And Articaine Groups. Patients Were Given A Tablet Of Ibuprofen 600 Mg Premedication One Hour Before Administration Of Local Anesthesia. Root Canal Treatment Was Performed In A Single Visit Using Revo-S Rotary System And Sodium Hypochlorite Irrigation For Cleaning And Shaping. Obturation Was Carried Out Using Lateral Compaction Technique And Resin Sealer. Patients Were Instructed To Rate Any Discomfort On The Numerical Rating Scale Through Access Preparation, Pulp Extirpation And Postoperatively. Pain Intensity Was Assigned Into 4 Categorical Scores: Score 1: None (0); Score (2): Mild (1-3); Score 3: Moderate (4-6); And Score 4: Severe (7-10). In The Current Study, The Primary Outcome Was The Pain Felt During Access Cavity Preparation And Secondary Outcomes Were Pain Felt In Radicular Pulp Extirpation And Postoperative Pain. Success Was Defined As No/mild Pain During Access Cavity Preparation. Chi Square Test And Mann Whitney U Test Were Used For Statistical Analysis. The Significance Level Was Set At P � 0.05.

Results: There Was No Statistically Significant Difference In The Number Of Cases That Reported Success In Lidocaine (n=10/26, 38.5%, N=16/26, 61.5%) Versus Articaine (n=13/26, 50%, N=19/26, 73.1%) During Access Cavity Preparation And Cleaning And Shaping, Respectively, With P Value �0.05. Postoperatively, There Was No Statistically Significant Difference Between The Two Groups At 6, 12 And 24 Hours; With P Values 0.884, 0.871 And 0.31, Respectively. Conclusion: Articaine Mandibular Buccal Infiltration Can Be An Alternative To Inferior Alveolar Nerve Block During Emergency Access Cavity In Mandibular Molars With Irreversible Pulpitis. None Of These Treatments Provides Satisfactory Profound Pulpal Anesthesia For For Mandibular Molars With Symptomatic Irreversible Pulpitis.
