Resin Infiltration Of Incipient Interproximal Caries: A 6-Month Randomized, Controlled Clinical Trial, Purvi Vaghela

Dental caries is the most widespread of all diseases. It causes destruction of tooth structure by dissolving the enamel first, then progressing to the dentin. While it is possible to replace carious tooth structure with invasive restorations, it is highly desirable to arrest or reverse the disease process so that the restorations can be avoided. One of the most difficult areas to clean or use preventive, non-surgical treatment is the contact area between teeth. Recently treatment with resin polymers to infiltrate enamel and dentin affected by caries has been in-troduced. The infiltration technique arrests the lesion progression by penetrating and …

A PROSPECTIVE RANDOMIZED CLINICAL TRIAL TO COMPARE FREE GINGIVAL GRAFTS AND CONNECTIVE TISSUE GRAFTS AROUND IMPLANTS WITH A LACK OF KERATINIZED MUCOSA JEFFREY T HSU PERIODONTOLOGY ABSTRACT Although evidence is equivocal regarding the need for keratinized mucosa around dental implants, the consensus among researchers and clinicians is that peri-implant keratinized mucosa is beneficial to the health and stability of the implant prosthesis. An adequate width of keratinized mucosa (WKM) provides a resistant barrier to bacterial infiltration, facilitates restorative procedures, improves esthetic outcomes, patient comfort, and ease of oral hygiene. Many surgical approaches have been used to increase WKM around dental …

Comparison Of Bone Augmentation Techniques In Extraction Sockets: A Soft And Hard Tissue Wound Healing Analysis, Pragya Sharma
All ETDs from UAB
The use of bone grafting materials in sockets after tooth extraction has become a common technique for the preservation of alveolar ridge dimensions for future dental implant placement. A number of growth factors have been used to accelerate healing and shorten the healing period between extraction and implant placement. This study presents a novel application of amniotic tissue allograft used as an adjunct to bone grafting with mineralized bone allograft after tooth extraction. Amniotic tissue contains a myriad of growth factors such as Epidermal Growth Factor (EGF), Transforming Growth Factor beta (TGF-β), Fibroblast Growth Factor (FGF), Platelet Derived Growth Factor …

All ETDs from UAB
Objective: To measure and compare the retention of zirconia crowns cemented with Ceramir (Calcium phosphate-based Bioactive Cement), RelyX Luting Plus (RMGI Cement) and RelyX Unicem (Self-adhesive resin cement) to extracted teeth following thermocycling. Methods: 30 sound extracted non-carious human molars were collected following IRB approval. The selected molars were notched at the roots and mounted into PVC molds filled with acrylic resin (Yates Motloid, USA). The occlusal surface was ground flat on a model trimmer. The axial reductions were performed with a standardized crown preparation device using a Komet 5845KR (“onlay”) diamond bur. A 10 degree ramp was used to …

Retention Of Resin Composite Cam Crowns Following Different Bonding Protocols, Amir Hossein Nejat
Retention Of Resin Composite Cam Crowns Following Different Bonding Protocols, Amir Hossein Nejat
All ETDs from UAB
Objectives: Resin composite CAM materials offer more efficient milling, however, there is a high incidence of clinical debonding when this material is used for full-coverage crowns. The aim of the present study is to evaluate the effect of different surface treat-ments and primers on the crown retention of a new resin composite CAM material. Methods: 120 molars were prepared with a 24 degree taper, 1.5mm height, and axial walls in dentin. Surface area was measured by digital microscopy and preparations were scanned with an intraoral scanner. Crowns were milled from an experimental com-posite material with 4mm occlusal height. Teeth were …
An In Vitro Evaluation Of Abutment Design For Anterior Zirconia Resin Bonded Restorations, Watcharapong Aroonsang
An In Vitro Evaluation Of Abutment Design For Anterior Zirconia Resin Bonded Restorations, Watcharapong Aroonsang
All ETDs from UAB
Resin-bonded fixed partial dentures (RBFPDs) have evolved from metal frameworks to esthetic all ceramic tooth colored restorations. However these restorations frequently fail due to a loss of retention of the retainers. As the frameworks for these restorations have changed to more esthetic ceramic materials, the search for the ideal conservative preparation design providing maximum retention is critical to improve the life span of these restorations. Purpose: This in vitro evaluation measured and compared the resistance and retention created with different abutment preparation designs with a zirconia framework. Method: 21 extracted human maxillary central incisors were divided into three groups of …

Osteoblast And Chondrocyte Specific Contribution Of The Runx2 Gene During The Development Of Cleidocranial Dysplasisa, Kayla Renee King
All ETDs from UAB
The Runx2 transcription factor is essential for the differentiation of mesenchymal stem cells into functional chondrocytes and osteoblasts. In humans, the haploinsufficiency of the Runx2 gene is associated with cleidocranial dysplasia (CCD). The CCD is characterized by short stature, open sutures and fontanels in the skull, hypoplastic clavicles and supernumerary teeth. Skeletal elements disrupted in CCD patients are developed by intramembranous and/or endochondral ossification. However, the cell type specific roles of the Runx2 gene in the development of CCD-associated skeletal defects remain unknown. The main goal of this research was to define the specific role of the Runx2 gene in …
