ABSTRACT

Objectives: The Aim Of Present Study Was To Assess The Vermillion Symmetry And Scar Quality In Surgical Management Of Patients With Unilateral Cleft Lip Using Orbicularis Oris Muscle Z-plasty Modified Millard?s Technique Versus Fisher?s Technique. Patients And Methods: Twenty Patients Were Selected With Primary Non-syndromic Unilateral Cleft Lip. The Patients Were Randomly Assigned In To Two Equal Groups Each Of Which Ten Patients. In Group I, Each Patient Received Unilateral Cleft Lip Repair Using Orbicularis Oris Muscle (OOM) Z-plasty Modified Millard?s Technique. While In Group II, Each Patient Received Unilateral Cleft Lip Repair Using Fisher?s Technique. In Both Groups The Vermillion Symmetry Of Repaired Cleft Side Was Evaluated And Measured In Comparison To The Non-cleft Side Of The Same Patient By Computerized Photogrammetric Lip Analysis Using ImageJ Software Version 1.50f. For Scar Evaluation, Objective Assessment Was Performed In Which The Measurements For Length And Width Were Obtained By The Same Manner Of Analysis As In Vermillion. In Addition To Scar Evaluation Using Vancouver Scar Scale At 6 Months.

Results: The Results Showed That, The Evaluation Of Vermillion Symmetry And Scar Quality Was Statistically Insignificant During The Different Follow-up Periods (1 Week, 3 Months And 6 Months) Between OOM Z-plasty Modified Millard?s Technique And Fisher?s Technique. Similarly, There Was No Significant Difference In Scar Evaluation Using Vancouver Scar Scale Between The Two Groups. Conclusion: Orbicularis Oris Muscle Z-plasty Modified Millard?s Technique Used In Surgical Treatment Of Unilateral Cleft Lip Is A Reliable Technique As Well As Fisher Technique. While Both Groups Showed Criteria Of Success, A Very Small Difference In Vermillion Notching Was Documented Favoring The OOM Z-plasty Modified Millard?s Technique.

ABSTRACT

Objectives: To Evaluate The Change In Mineral Content And Ultra-morphological Picture Of Demineralized Enamel After Being Treated With NovaMin Application With And Without Poly-acrylic Acid- Bioactive Glass Powder Air Abrasion After 24 Hours And 3 Month From The Remineralization Period.

Materials and Methods: Eleven Sound Extracted Premolar Human Teeth Were Used. Each Tooth Was Divided Into 2 Halves (22 Specimens) The Buccal For Group P1 (preconditioned Group) And The Lingual For Group P2 (no Preconditioning). Specimens Were Assessed Before (T0), After (T1) Demineralization, After 24 Hours (T2) And Three Months (T3) From The Remineralization Period And Storage In Artificial Saliva. Pre-conditioning Was Induced By Air-abrasion Using Bioactive Glass 45S5 And Polyacrylic Acid Powder Mixture. Subsequently, Specimens Were Treated By NovaMin (Restore-DR Collins-USA). Quantitative Energy Dispersive X-ray Spectroscopy Elemental Analysis Was Performed On Enamel To Determine Ca/P Ratio Levels. The Ultra-morphological Analysis Was Done Using The Environmental Scanning Electron Microscope To Determine The Interprismatic Distance.

Results: 24 Hours After Remineralization Period Group Revealed The Highest Ca/P Ratio For Both Preconditioned And Without Preconditioning Protocols. Three Months After Remineralization And Intact Enamel Showed Similar Ca/P Ratio Mean Values. The Highest Inter-prismatic Space And The Lowest Ca/P Ratio Were Recorded In The Demineralized Groups. The Lowest Interprismatic Space Was Shown In The Intact Enamel Conclusion: Enamel Preconditioning With Bioactive Glass Did Not Play A Role In Its Remineralization. Novamin Is A Successful Remineralizing Agent. Time Had No Effect On The Enhancement Of The Already Remineralized Enamel.

ABSTRACT

Objectives: Evaluate The Diagnostic Accuracy Of Planmeca ProMax 3D Mid CBCT Unit With Different Voxel Sizes (0.075 Mm, 0.2 Mm, And 0.4 Mm) In Detection Of Second Mesiobuccal Canal In Maxillary Molars As Compared To Clinical Sectioning Of The Tooth (gold Standard).

Materials & Methods: This Study Was Performed On Twenty Four Maxillary Molars Fulfilling The Inclusion Criteria. The Molars Were Inserted In Acrylic Models, With Six Teeth Embedded In Each Model Using Inlay Wax For Support. The Acrylic Cast Was Placed In A Plastic Container Filled With Water To Simulate The Soft Tissues. All Acrylic Casts Were Scanned Using Planmeca ProMax 3D Mid CBCT Machine (Helsinki, Finland). All Molars Were Radiographed Using Three Different Voxel Sizes (0.075 Mm, 0.2mm & 0.4mm). After That, The Scans Were Assessed By Two Radiologists Twice With Two Weeks Interval For Inter And Intra-observer Agreement. The Reference Standard In This Study Was The Clinical Sectioning Of The Second Mesiobuccal Root Using The Bronwill Microtome. The Mesiobuccal Root Was Cut Into Two Sections And Visually Evaluated. All Data Were Collected, Tabulated And Subjected To Statistical Analysis.

Results: From The 24 Maxillary Molars, 13 Had Two Mesiobuccal Canals After The Analysis Of The Transverse Sections (gold Standard). The Results Of This Study Revealed That The Sensitivity, Specificity And Accuracy Of CBCT Images Increase As The Voxel Size Decrease. However, Statistical Analysis Showed That There Was No Statistical Significant Difference Between The Three Voxel Sizes In The Ability To Detect The MB2 Canal (p > 0.05). Inter- And Intra-observer Agreement Showed Very Good Agreement (0.81?1) In The Detection Of MB2 Canal In Maxillary Molars. Conclusion: The Planmeca ProMax 3D Mid CBCT Unit Is Able To Detect The MB2 Canal Of Maxillary Molars Accurately. The Smaller The Voxel Size, The Higher The Image Resolution And Image Quality.
