ABSTRACT
AIM: The Aim Of This Study Is To Evaluate Implant Stability, Radiographic Bone Changes In Terms Of Horizontal And Vertical Bone Loss And Pink Esthetic Score In Immediate Implant Installation And Immediate Provisionalization With And Without Grafting The Jumping Gap With A Mixture Of 1:1 Autogenous And Xenograft Particulates.Methodology: Twenty- Four Patients With Non-restorable Single Tooth In The Maxillary Anterior Region Indicated For Extraction Were Enrolled In This Study, All Received Immediate Implant Placement With Immediate Temporization. These Patients Were Randomly Selected From The Outpatient Clinic Of The Oral And Maxillofacial Department Of Cairo University And Equally Divided Into Study And Control Group. The Twelve Patients In The Study Group Received A Treatment Of Grafting The Jumping Distance Created After Implant Placement. This Graft Was A Mixture Of 1:1 Xenograft To Autogenous Bone Particulates. The Autogenous Bone Was Collected By Low-speed Drilling From Within The Socket. The Twelve Patients Of The Control Group Did Not Receive The Graft. Outcome Measures Were: Secondary Implant Stability, Amount Of Marginal Bone Loss (Horizontal And Vertical), PES After 6 Months.

Results: The Mean Implant Stability Quotient For Study Group Was 68.5?3.1 And Increased To 77.6?3.7 After 6 Months, While For The Control Group It Was 66.3?5.4 And Increased To 74.2?4.5 After 6 Months. Mean Results Regarding Horizontal Bone Loss At Platform Level For Study Group Was 0.09? 0.06 And Was 0.26?0.27 For Control Group, At Mid-implant Level Was 0.5?0.26 For Study Group And 0.43?0.48 For Contro1 Group, At Apex Level Mean Results Were 0.42?0.25 For Study Group And 0.59?0.52 For Control Group. While Mean Results Of Vertical Bone Loss At Labial Implant Surface Were 1.41?0.4 For The Study Group And 1.37 ? 0.38 For The Control Group, And Were -0.1?0.34 For Study Group And 0.21?0.24 For The Control Group At Palatal Implant Surface.This Clearly Shows The Difference In Tissues Stability Between Grafted & Graft-less Jumping Gap In Immediate Implant Placement. The Mean Pink Esthetic Score For The Study Group Was 11.58?1.16 And Increased To 12.42?1.44 After 6 Months And Was 11.75?1.71 And Decreased To 11.17?1.53 After 6 Months For The Control Group. Conclusion: Within The Limitations Of The Study, It Is Impossible To Prevent Bone And Soft Tissue Changes After Tooth Extraction Even When A Graft Is Attempted To Be Placed At The Immediate Implant?s Jumping Gap. However, Grafting The Jumping Distance While Using The Immediate Implant Placement And Immediate Temporization Technique Has Superior Results Than Not Grafting In Terms Of Secondary Stability And Marginal Bone Loss As Well As Pink Esthetic Score.

ABSTRACT
This Study Aims To Evaluate The Correlation Of Head And Neck Postural Changes In Sagittal Profilein Skeletal Class III Patients After Orthognathic Surgery By Using 2D Measurements. 10 Adults With Class III Malocclusions Were Examined, And Three Angular Parameters Were Determined Using Cephalometric X-Ray In Natural Head Position Taken Before And After 6 Months Of The Operation, With The Mandibles Occluding At The Centric Relation For Evaluating The Head And Neck Postural Changes After Orthognathic Surgery, The Patients 2D Database Were Imported To Measure The Cranio-cervical Angles, Cervico Horizontal Angles And Cranio Vertical Angle. The Results Showed That There Is No Statistically Signifiant Changes In Cranio-cervical Angles, The Analysis Showed That The Correlation Coefficient Were Similar In The Two Head Positions Investigated And No Distinction Is Made Therefore Between The Findig In The Two Head Position. The Findins, Particularly With Regard To The Use Of 2D As A Diagnostic Aid For Subjects Affected By Dentofacial Deformity, Do Not Support Existence Of Clinically And Statistically Relevant Correlations Between Skeletal Class III Traits And Head And Neck Posture.

ABSTRACT


Aim: The Study Was Conducted To Assess The Fracture Resistance Of Zirconia Reinforced Lithium Silicate All Ceramic Material ?Celtra Press? Compared To Lithium Disilicate One ?IPS E-max Press? Under Simulated Oral Conditions.Methodology: Fourteen Ceramic Crowns Were Fabricated On Epoxy Dies Which Were Duplicated From Stainless Steel Master Die And Divided Into Two Equal Groups (n=7) According To The Material Of Construction; Group A: Crowns Fabricated With IPS E-max Press Material And Group B: Crowns Fabricated With Celtra Press Material. The Crowns Were Then Cemented Onto Their Corresponding Dies With A Self-adhesive Resin Cement And Subjected To Thermocycling And Cyclic Loading. Then They Were Loaded To Fractur In A Universal Testing Machine. The Results Were Tabulated And Statistically Analyzed Using Kolmogorov-Smirnov And Shapiro-Wilk Tests. Student T-test Used To Compare Mean Values. The Significancelevel Was Set At P ? 0.05 And 95% Confidenceinterval. Statistical Analysis Was Performed Using Graph Pad Instat (Graph Pad, Inc.) Software For Windows

Results: The Mean ? SD Values Of Fracture Resistance Were Recorded For Lithium Disilicate Group (1706.01 ?154.32 N) Meanwhile The Mean ? SD Value Recorded With Celtra Group Were (1550.67?196.71 N). Conclusion: Zirconia Reinforced Lithium Silicate Ceramic Crowns Produced Comparable Fracture Resistance Values To Lithium Disilicate Ceramic Crowns And Both Tested Materials Are Within The Clinically Acceptable Values In The Posterior Area.

ABSTRACT
The Aim Of The Present Study Was To Compare The Uses Of PRP And The Hyaluronic Acid (HA) In Treatment Of Temporomandibular Joint (TMJ) Internal Derangement.Patients Meeting The Research Diagnostic Criteria For TMJ Internal Derangement Were Assigned To 1 Of 3 Study Groups That Received Either PRP, HA Or Arthrocentesis Alone. The Outcome Variables Were Maximum Non-assisted Mouth Opening (MVMO), Joint Sounds, And Pain Index Scores. Descriptive And Bivariate Statistics Were Computed.Thirty Patients With TMJ Internal Derangement Were Enrolled In The Study. In Group I, 10 Patients Received Three Injections Of 1 ML Of PRP After Single Needle Arthrocentesis. In Group II, 10 Patients Received Three Injections Of 1 ML Of Low Molecular Weight HA After Single Needle Arthrocentesis. In Group III 10 Patients Received Single Needle Arthrocentesis Alone.Between-group Comparisons Of The Outcome Variables Over Time Revealed Significantimprovements In Group I The PRP Group Exhibited Better Performance Compared With The HA Group In Terms Of The Pain And Joint Sounds. The Improvements Obtained With The PRP Injections In Group I Were Maintained During The Follow-up Period, And At The End Of This Period, The Median MVMO Was Better Than Group II.The Results Of This Study Suggest That Autologous Intra-articular Injections Of PRP Performed Better Than HA And Lavage Only In The Treatment And They Both Better Than The Simple Lavage Alone (Arthrocentesis). The Results Of This Study Were Supported By The Results Of Studies Conducted By K?t?k Et Al, Hegab Et. Al, M. Hanc? Et Al, Kilic Et Al.

ABSTRACT

Objectives: The Aim Of This Prospective Randomized Clinical Trial Was Compare Between 2% Mepivacaine And 4% Articaine For Inferior Alveolar Nerve Blocks In Patients With Symptomatic Irreversible Pulpitis In Mandibular Molars As Regards To Their Anesthetic Efficiency;during Access Cavity Preparation And Instrumentation.Subjects And Methods: Sixty-six Patients Diagnosed Clinically And Radiographically With Symptomatic Irreversible Pulpitis In Mandibular Posterior Teeth Received Single-visit Root Canal Treatment Using ProTaper Universal Rotary System For Canal Preparation, They Were Randomly Divided Into Two Groups (n=33) According To The Anesthetic Solution Used, Either Group M (3.6 Ml Mepivacaine Hydrochloride 2% With 1:100000 Epinephrine) Or Group A (3.4 Ml Articaine Hydrochloride 4% With 1:100000 Epinephrine). The Pain Was Assessed Using Numerical Rating Scale (NRS) During Access Cavity Preparation And Instrumentation, Then The Need For Supplemental Anesthesia Was Also Recorded.

Results: There Was No Statistically Significantdifference In Pain Level Between Both Groups At The Different Observation Times. The Success Rates Were Similar In Both Groups (54.5% And 63.4% In Mepivacaine And Articaine Groups Respectively) With No Difference In The Need For Supplemental Anesthesia In Both Groups.Conclusion: The Anesthetic Efficacyof Mepivacaine And Articaine Seemed To Be Similar, Although Both Did Not Provide Acceptable Rate Of Anesthetic Success.
