A Methodology For Three-Dimensional Quantification Of Anterior Tooth Width, L. Thomas Johnson, Thomas W. Radmer, Alexis D. Visotcky, Kwang Woo Ahn, Daniel D. Blinka, Thomas Wirtz

School of Dentistry Faculty Research and Publications

The use of cone-beam computed tomography (CBCT) technology has been shown to be more accurate in measuring individual incisor tooth widths than the use of wax exemplars. There were fewer differences by investigators using CBCT than others using an F-test in a mixed model of the measurement differences of investigators, wax type, and which tooth was measured. In addition, the frequency of outliers was less in the CBCT method (a total of 5) as compared to the two-dimensional measurements in ether Aluwax (a total of 8) or Coprwax (a total of 12). Both results indicate that CBCT measurements accounted more …

Giant Mandibular Condyle Osteoma, Luis Eduardo Almeida, Marco Antonio De Oliveira Filho

School of Dentistry Faculty Research and Publications

Osteomas are benign tumors composed of mature compact or cancellous bone. They represent an uncommon lesion that occurs mainly in craniofacial complex bones. In jaws, they can appear on the bone surface as a polypoid or sessile mass, characterizing a peripheral osteoma (PO), or can be a lesion in the medullar space, then it is called central osteoma. In view of the scarcely reported cases about POs, this article presents a case of PO of the maxillofacial area that was surgically resected using hemicoronal approach.

Apoptosis In Displaced Temporomandibular Joint Disc With And Without Reduction: An Immunohistochemical Study, Carla Loreto, Luis Eduardo Almeida, Paula C. Trevilatto, Rosalia Leonardi

School of Dentistry Faculty Research and Publications

Internal derangement (ID) of the temporomandibular joint (TMJ) is due to an abnormal relationship of the articular disc to the mandibular condyle, glenoid fossa and articular eminence. The two most common types of internal derangement are anterior disc displacement with (ADDwR) and without reduction (ADDwoR). Disc displacement is associated with degenerative tissue changes. The histological features of discs from patients with TMJ ID reflect a general remodelling caused by abnormal loading. A correlation has been demonstrated between TMJ ID and apoptosis. Few investigations have addressed the role of apoptosis or caspase activity in TMJ ID. The apoptosis activation process was …

New Phosphated Poly(Methyl Methacrylate) Polymers For The Prevention Of Denture-Induced Microbial Infection: An In Vitro Study, Antony Raj, Andrew R. Dentino

School of Dentistry Faculty Research and Publications

Purpose: Poly(methyl methacrylate) (PMMA) has been widely used as a denture-base acrylic resin due to its excellent physical and mechanical properties. However, the material is highly prone to microbial fouling that often leads to Candida-associated denture stomatitis. Incorporation of phosphate groups into PMMA could facilitate adsorption of salivary antimicrobials and inhibit microbial adherence on the polymer surface. An in vitro study evaluated PMMA polymers containing varying amounts of phosphate group for their efficacy to inhibit Candida albicans adhesion, adsorb salivary histatin 5, and exhibit candidacidal activity.

Methods: Six PMMA polymers containing 0%, 5%, 15%, 10%, 20%, and 25% of …

The Epithelioid Blue Nevus: A Rare Intraoral Nevomelanocytic Tumor, Atef Hanna, Swati Y. Rawal, Kenneth M. Anderson, Yeshwant B. Rawal

School of Dentistry Faculty Research and Publications

The epithelioid blue nevus (EBN) is considered a cutaneous marker of the Carney complex. Sporadic EBN has been reported in patients not exhibiting the Carney complex. The EBN does not exhibit unique clinical features that help to differentiate it from other lesions and is often provisionally diagnosed as an acquired melanocytic nevus, or a malignant melanoma. A 52-year-old African-American female had a 3-4 mm bluish macule of the left anterior hard palate. An excisional biopsy was performed to rule out an incipient melanoma. Formalin-fixed, hematoxylin and eosin-stained sections were examined microscopically. On the basis of histopathological features, a diagnosis of …

Gingival Abscess Removal Using A Soft-Tissue Laser, Soni Prasad, Edward A. Monaco, Jr., Sebastiano Andreana

School of Dentistry Faculty Research and Publications

Gingival abscess, also known as parulis, is defined as a localized, acute inflammatory lesion that may arise from a number of sources, including microbial plaque infection, trauma, and foreign body impaction. It often presents as a smooth, fluctuant, red-color swelling and can occasionally be painful. It is generally limited to marginal and interdental gingiva. Based on its location it has been classified as a type of periodontal abscess which does not involve any attachment loss. The treatment comprises of removal of the cause and, in acute situations, excision of the abscess. A typical gingival abscess is easy to diagnose; however, …

School of Dentistry Faculty Research and Publications

To evaluate the apoptosis involvement in the angiogenesis as a self-limiting process in patients with temporomandibular joint (TMJ) degenerated disc vessels, we assessed, by immunohistochemistry, the detection of TRAIL, its death receptor DR5 and caspase 3. TRAIL, its death receptor DR5 and caspase 3 expression were studied by immunohistochemistry in 15 TMJ discs displaced without reduction and in 4 unaffected discs. These apoptosis molecules were detected in the intima and media layers of newly formed vessels affected discs. In conclusion, vessels apoptosis activation in TMJ disc with ID could be regarded as a self-limiting process that try to leads to …

Soft Tissue Grafting To Improve Implant Esthetics, Moawi M. Kassab

School of Dentistry Faculty Research and Publications

Dental implants are becoming the treatment of choice to replace missing teeth, especially if the adjacent teeth are free of restorations. When minimal bone width is present, implant placement becomes a challenge and often resulting in recession and dehiscence around the implant that leads to subsequent gingival recession. To correct such defect, the author turned to soft tissue autografting and allografting to correct a buccal dehiscence around tooth #24 after a malpositioned implant placed by a different surgeon. A 25-year-old woman presented with the chief complaint of gingival recession and exposure of implant threads around tooth #24. The patient received …

Effect Of Low-Magnitude, High-Frequency Vibration On Osteocytes In The Regulation Of Osteoclasts, Esther Lau, Saja Al-Dujaili, Axel Guenther, Dawei Liu, Liyun Wang, Lidan You

School of Dentistry Faculty Research and Publications

Osteocytes are well evidenced to be the major mechanosensor in bone, responsible for sending signals to the effector cells (osteoblasts and osteoclasts) that carry out bone formation and resorption. Consistent with this hypothesis, it has been shown that osteocytes release various soluble factors (e.g. transforming growth factor-β, nitric oxide, and prostaglandins) that influence osteoblastic and osteoclastic activities when subjected to a variety of mechanical stimuli, including fluid flow, hydrostatic pressure, and mechanical stretching. Recently, low-magnitude, high-frequency (LMHF) vibration (e.g., acceleration less than < 1 × g, where g = 9.81 m/s², at 20–90 Hz) has gained much interest as studies …

Tooth Loss, Apolipoprotein E, And Decline In Delayed Word Recall, P. S. Stein, R. J. Kryscio, M. Desrosiers, Sara J. Donegan, M. B. Gibbs

School of Dentistry Faculty Research and Publications

Our previous research suggests an association between a low number of teeth and increased risk of dementia. The aim of the present study was to determine if a low number of teeth is specifically related to memory decline as evidenced by low Delayed Word Recall scores. In addition, we examined the combined effect of a low number of teeth and the apolipoprotein E ϵ4 allele on Delayed Word Recall scores. We hypothesized that the scores of those who had the allele and a low number of teeth (0-9) would decline more rapidly over time than those participants with a greater …

Quantifying Fluid Shear Stress In A Rocking Culture Dish, Xiaozhou Zhou, Dawei Liu, Lidan You, Liyun Wang

School of Dentistry Faculty Research and Publications

Fluid shear stress (FSS) is an important stimulus for cell functions. Compared with the well established parallel-plate and cone-and-plate systems, a rocking “see-saw” system offers some advantages such as easy operation, low cost, and high throughput. However, the FSS spatiotemporal pattern in the system has not been quantified. In the present study, we developed a lubrication-based model to analyze the FSS distributions in a rocking rectangular culture dish. We identified an important parameter (the critical flip angle) that dictates the overall FSS behaviors and suggested the right conditions to achieving temporally oscillating and spatially relatively uniform FSS. If the maximal …

The Quantification Of Tooth Displacement, Thomas W. Radmer, L Thomas Johnson, Mingan Yang, Thomas Wirtz

School of Dentistry Faculty Research and Publications

By using reference points from a single pixel marker placed at the center point of the cuspid teeth and the center point on each of the incisor teeth, a polynomial curve was generated as a native curve for each dental arch studied. The polynomial curve generated from actual tooth position in each arch provides the forensic odontologist with another reference point that is quantifiable. The study represents that individual characteristics, such as tooth displacement, can be quantified in a simple, reliable, and repeatable format.
