ABSTRACT
BACKGROUND: Several Patients Notice The Value Of Completely Edentulous Mandibular Ridge Therapy Through Complete Overdenture Implants To Be On The Far Side Their Money Scope, Mandibular Overdentures Reatined By One Implant Are Reported To Be More Leisurely And Function Better Than Conventional Complete Dentures. The Goal Of The Current Study Were To Analyze The Clinical Outcomes In Comparison Between Two Types Of Attachments, The Locator Attachment Versus The Equator Attachment Used With Immediately Loaded Single Implant Retained Mandibular Overdenture Opposing Conventional Complete Denture. METHODS: Ten Completely Edentulous Patients Were Managed With A Single Implant Inserted Into The Midline Of The Mandible, Followed By Rehabilitation With Complete Dentures And Divided Into Two Equal Groups: Group I Patients Receive Locator Attachment, While Group II Receive Equator Attachment. Immediately After Implant Placement The Implant Stability Quotient (ISQ) Reading Of A Minimum Of 60 Was Measured Before Considering Connection Of The Attachment. Then The Denture Was Relieved In The Midline Providing Adequate Space For Female Housing Of The Attachment And Then The Denture Was Picked Up Directly In The Mouth. The Clinical Outcome Evaluated Two Weeks, Three Months And Six Months After Implant Insertion. RESULTS: The Peri-implant Soft Tissues Assessment Results Showed No Statistically Significant Difference Within Each Group And Between Two Groups At Different Evaluation Period, But The Result Of The Probe Depth In The Present Study Showed Statistically Significant Increase Within The Pair Groups, But There Is No Significant Variation Between The Pair Groups. CONCLUSION: Immediately Loaded Single Midline Implant Retained Mandibular Overdenture Treatment With Locator Attachment Could Be An Alternative And Cost Effective Treatment Option And Relatively Simply Treatment.

ABSTRACT
Horizontal Ridge Deficiency In The Anterior Maxilla Represents One Of The Challenging Situation In Bone Regeneration. Guided Bone Regeneration (GBR) Has Become A Major Treatment Option For Such Deficiency To Provide Optimal Bone Quantity For Installation Of Endosseous Dental Implants. However, There Is A Good Prognosis For This Treatment, As The Residual Ridge Height Can Be Used To Stabilize A Bone Graft, Making It Less Subjectable To Move Which Is One Of The Factors That May Lead To Graft Failure. Numerous Technique In Guided Bone Regeneration Have Been Introduced Using A Varies Types, Combinations Of Grafting Materials And Different Types Of Barrier Membranes Either Rigid, Non-rigid Or Resorbable, Non-resorbable Materials.

ABSTRACT


Aim: The Present Study Was Performed To Evaluate The Post-operative Pain Reduction After Application Of Three Intracanal Medicament Within Necrotic Root Canals. Material And Method: Thirty Three Medically Free Patients With Necrotic Single Rooted Teeth Were Randomly Assigned Into Three Groups According To Intracanal Medicament Used; Conventional Calcium Hydroxide Paste, Calcium Hydroxide Nanoparticle And Combined Calcium Hydroxide With Silver Nanoparticle. After Opening Access Cavity And Completing Mechanical Preparation, Proper Irrigation And Dryness Of The Canals, Application Of Intracanal Medication Was Done. Patients Were Instructed To Record Their Postoperative Pain Level In Pain Chart (Numerical Rating Scale (NRS)) After 6, 24 And 48 Hours.

Results: There Was No Statistically Significant Difference Between The Three Groups At 6 And 24 Hours But There Was A Statistically Significant Difference Between Them After 48hours. Conclusion: The Combination Of Calcium Hydroxide With Silver Nanoparticle As Intracanal Medication Could Be Used As An Alternative For Reduction Of Postoperative Pain.

ABSTRACT
Purpose To Evaluation The Effect Of Deep Marginal Elevation Technique On Fracture Force Of CAD-CAM-fabricated Overlay Restorations Using Hybrid Ceramic Material (VITA Enamic). Materials And Methods Twenty Overlay Restorations Were Constructed In This Study. The Samples Were Divided Into Two Main Groups According To The Ceramic Material (n=10). The Type Of Ceramics That Was Used Is (vita Enamic). The First Group: VITA ENAMMIC Hybrid Ceramic Overlays Without Deep Marginal Elevation (DME). The Second Group: VITA ENAMMIC Hybrid Ceramic Overlays With Deep Marginal Elevation (DME). The Two Main Groups Was Cemented By RelyX Ultimate Clicker Resin Cement.

Results: There Was A Significant Difference Between The Vita Enamic Material With DME And Without DME Technique. The First Group Was Higher Than The Second Group. Conclusion: Although The Deep Marginal Elevation Technique Has A Lower Fracture Strength But It Is Considered A Promising Treatment.

ABSTRACT


Aim: The Present Study Aimed To Evaluate And Compare Of The Incidence And Propagation Of Apical Cracks After Root Canal Obturation Using Lateral Compaction And Vertical Compaction Technique.

Materials and Methods: A Total Of 20 Human Mandibular Single Rooted Premolars With Single Straight Root Canals Were Used In This Study. After Decoronation, One Millimeter From The Apex Of Each Tooth Was Ground Perpendicular To The Long Axis To Remove Apical Ramifications.Instrumentation Was Done Using Fanta Rotary Filesto File40 Taper 4%. Samples Were Randomly Divided Into Two Experimental Groups (n = 10) According To The Obturation Technique Used Either Lateral Compaction Or Warm Vertical Compaction Using Totalfillbioceramic Sealer. Four Digital Images Of The Resected Apical Root Surface Were Recorded For Each Specimen, Baseline, After Preparation, Immediately After Flling, And After 14 Days. The Images Were Then Inspected For The Presence Of Any New Apical Cracks And Propagation. Mann-Whitney U Test Was Used To Compare Between The Two Groups. Friedman?s Test Followed By Dunn?s Test Was Used To Study The Changes Within Each Group

Results: After Instrumentation; There Was No Statistically Significantdifference Between Incidence Of Cracks In The Two Groups (P-value = 1, Effect Size = 1). Both Groups Showed The Same Incidence Of Cracks (80%). After Obturation As Well As After 14 Days; There Was No Statistically Significantdifference Between Incidence Of Cracks In The Two Groups (P-value = 0.474, Effect Size = 2.25) And (P-value = 0.474, Effect Size = 2.25), Respectively. Warm Vertical Compaction Group Showed Higher Incidence Of Cracks Than Lateral Condensation Group (100% And 80%, Respectively). Warm Vertical Compaction Technique Is 2.25 Folds Prone To Crack Compared To Lateral Condensation Technique. After Obturation As Well As After 14 Days; Lateral Condensation Group Showed Statistically Significantlyhigher Crack Propagation Measurements Than Warm Vertical Compaction Group (P-value = 0.039, Effect Size = 1.099) And (P-value = 0.039, Effect Size = 1.099), Respectively.

Conclusions: Dentinal Defects Were More Significantlyattributed To The Role Of Root Canal Instrumentation Rather Than The Type Of Obturation Technique.

ABSTRACT


Aim: This Study Was Conducted To Evaluate And Compare The Thickness Of Calcificbridge Formed By Indirect Pulp Capping Using Light Activated Calcium Silicate Versus Light Activated Calcium Hydroxide, Immediately After Restoration And One Year Later Using Digital Radiography.Methodology: 30 Participants Were Recruited In This Study For Having 60 Molars With Deep Occlusal Carious Lesions. Molars Of Each Patient Were Randomly Divided Into Two Groups Treated With Partial Caries Removal Technique The Firstgroup Represented Teeth Treated With Application Of Light Activated Calcium Silicate (TheraCal) Prior To Finalpermanent Resin Composite Restoration, The Second Group (comparator Group) Represented Teeth Treated With Light Activated Calcium Hydroxide. Radiographic Images Were Obtained And Radiographic Dentin Bridge Thicknesses Were Evaluated Using Digora For Windows Computer Software At Baseline Immediately After Restoration And After One Year.

Results: The Formed Dentin Bridge Thickness Was Thicker In The Calcium Hydroxide Group Than Calcium Silicate Group (0.24%mm And 0.16%mm Respectively) And The Percentage Of Change In Dentin Bridge Thickness After One Year Was Thicker In Calcium Hydroxide Group Than Calcium Silicate (TheraCal) Group (24% And 16.26% Respectively).

Conclusions: Calcium Hydroxide Is Still Effective As A Pulp Capping Material Compared To Resin Modified Calcium Silicate
