ABSTRACT


Aim: To Evaluate The Success Rate Of Hall Technique And Indirect Pulp Capping For Managing Primary Molars With Deep Carious Lesions In A Group Of Egyptian Children. Subjects & Methods: A Total Sample Size Of 74 Mandibular Primary Molars. Patients Were Randomly Divided Into 2 Equal Groups, Group A (Hall Technique) And Group B (Indirect Pulp Capping). Indirect Pulp Capping In The Current Study Was Performed Then Teeth Were Finally Covered By Preformed Metal Crowns. Clinical And Radiographic Assessments Were Performed At 3, 6 And 9 Months Postoperatively. Hall Technique Was Performed, And Clinical And Radiographic Assessments Were Performed At 3, 6 And 9 Months Postoperatively.

Results: The Results Of The Study Showed Insignificant Difference Between Both Groups Regarding Postoperative Pain. On Comparing The Overall Clinical Success Of The Two Groups At 3, 6 And 9 Months Group B (IPC) Showed Higher Clinical Success Than Group A (HT). However, There Was No Statistically Significant Difference Between The Two Groups. While, When Comparing The Overall Radiographic Success Between Group A And Group B At 3, 6 And 9 Months; Both Showed 100% Radiographic Success With No Difference Between The Two Groups.

Conclusions: The Hall Technique Appears To Offer An Effective Treatment Option For Carious Primary Molars And It Is A Simplified Method And Considered Easier Than Conventional Restorative Treatment Of Carious Lesions. The Clinical And Radiographic Success Of The Hall Technique Is Comparable To Indirect Pulp Capping.

ABSTRACT
Background: There Is Little Number Of Studies That Address The Inter-relationship Of Gestational Diabetes Mellitus (GDM) And Periodontitis During Pregnancy. Hence, This Study Was Conducted To Provide Further Evidence In The Possible Association Between Chronic Periodontitis And GDM By Evaluating The Level Of Tumor Necrosis Factor-alpha (TNF-�) Of Chronic Periodontitis Patients With GDM After Phase I Periodontal Therapy. Subjects And Methods: This Study Was Conducted On 40 Subjects Divided Into 2 Groups: 20 Pregnant Females Suffering From Gestational Diabetes Mellitus Associated With Moderate To Severe Chronic Periodontitis And 20 Systemically Free Pregnant Females Suffering From Moderate To Severe Chronic Periodontitis. The Periodontal Status Of The Subjects Was Assessed At Baseline Before Phase I Periodontal Therapy And 2 Months After Completion Of The Treatment: All Subjects Have Been Screened By Comprehensive Periodontal Examination And Full Periodontal Charts Were Obtained. The Following Clinical Parameters Were Assessed To Determine The Clinical Periodontal Status Of Patients: Plaque Index (PI), Gingival Index (GI), Probing Pocket Depth (PPD), And Clinical Attachment Level (CAL). Gingival Crevicular Fluid (GCF) And Serum Samples Were Collected From Both Study Groups To Detect TNF-� Levels. Regarding The Assessment Of TNF-�, Real-time Reverse-transcriptase Polymerase Chain Reaction (RT) PCR Technique Was Used.

Results: Results Of The Present Study Observed Statistically Significant Reduction In TNF-� Levels After 2 Months From Phase I Periodontal Therapy. The Current Study Showed That, There Was A Statistically Significant Positive (direct) Correlation Between TNF-� Level, PI, GI, PPD And CAL Measurement At Baseline And After 2 Months From Phase I Periodontal Therapy. Conclusion: It Is Shown That The Levels Of TNF-� In GCF And Serum Before Treatment Were Higher In GDM Group (group 1) Than In The Control Group. Thus, The Examination Of TNF-� May Enhance The Understanding Of Pathogenesis Of Periodontitis And GDM And Its Assessment In The Treatment Process May Result In Better Control Of The Disease.

ABSTRACT


Purpose: This Preliminary Study Was To Evaluate Clinically And Radiographically The Volume Changes Of Alveolar Bone Grafting Guided By Resorb-x Membrane. Patients And Methods: A Total Of Six Patients With Maxillary Anterior Localized Alveolar Ridge Defects � 3 Mm Were Selected. The Alveolar Ridges Were Reconstructed With Xenogeneic Bone Graft Particles Guided By Resorb-x Membrane. Linear Measurements And Volume Analysis Of The Changes In Alveolar Ridge Were Obtained Pre-operatively And Four Months Post-operative Using Cone Beam Computed Tomography (CBCT).

Results: Four Months Postoperatively, All Treated Defect Sites Exhibited Satisfactory Bone Formation. Clinical Results Showed Absence Of Any Foreign-body Reactions To Biodegradation Of Resorb-x Membrane And SonicPin Rx?. Measurements Made On CBCT, Four Months Postoperative Showed Statistically Significant Increase In Bone Width With Mean � SD: 2.37 � 1.77 Mm At 2 Mm, 2.46 � 1.56 Mm At 4 Mm, 2.36 � 1.05 Mm And 1.63 � 0.83 Mm At 8 Mm From Crest Of Alveolar Ridge Respectively. There Was Statistically Significant Increase In Bone Volume By 36.15% In The Area Of Newly Formed Bone. No Statistical Significant Changes Was Found In The Density Of Newly Formed Bone When Compared To The Density Of The Native Bone Four Months Post-operatively. Conclusion: The Resorb-x Membrane Is An Improvement In The Search For A Mechanically Strong And Stiff As Well As A Biodegradable System. With Such Modifications In Properties, This Gives Resorb-x Membrane More Promising Chances To Be Used In Guided Bone Regeneration.
