The Dental Safety Net In Montgomery County: A Status Report, Sequoia Y. Butcher

Master of Public Health Program Student Publications

Background: Adult oral health has been identified as a major public health problem by the United States Surgeon General. A substantial number of adults between the ages of 20 and 64 have untreated tooth decay. There are limited treatment options for adults without dental insurance. Low-income adults must turn to free/low cost clinics, or private dentists that accept Medicaid to receive dental care. However, these resources are often limited. When the resources are not available these adults are left to deal with untreated tooth decay which can lead to worsening conditions and other health issues.

Methods: Eleven key-informant interviews were …

Effect Of Voxel Size On The Accuracy Of 3d Reconstructions With Cone Beam Ct., Delphine Maret, Norbert Telmon, Ove A. Peters, B. Lepage, J. Treil, J. M. Inglèse, A. Peyre, Jean-Luc Kahn, Michel Sixou

All Dugoni School of Dentistry Faculty Articles

OBJECTIVES: The various types of cone beam CT (CBCT) differ in several technical characteristics, notably their spatial resolution, which is defined by the acquisition voxel size. However, data are still lacking on the effects of voxel size on the metric accuracy of three-dimensional (3D) reconstructions. This study was designed to assess the effect of isotropic voxel size on the 3D reconstruction accuracy and reproducibility of CBCT data.

METHODS: The study sample comprised 70 teeth (from the Institut d'Anatomie Normale, Strasbourg, France). The teeth were scanned with a KODAK 9500 3D® CBCT (Carestream Health, Inc., Marne-la-Vallée, France), which has two voxel …

Intra- And Inter-Examiner Reliability Of Direct Facial Soft Tissue Measurements Using Digital Calipers, Nikolay Mollov, Jose A. Bosio, Jessica E. Pruszynski, Thomas S. Wirtz

School of Dentistry Faculty Research and Publications

Background: The objective of this study is to determine if facial soft tissue measurements using digital calipers can be reliably taken by the same examiner and by a large group of examiners.

Materials and Methods: Ten examiners performed a set of 18 in-clinic measurements on 10 female and 10 male dental students using a digital caliper twice over a 3-week period. The intra-class correlation coefficient and the Shrout-Fleiss method were used for the statistical analysis.

Results: Anthropometric intra-examiner reliability was high for all measurements (none fell below R = 0.934). However, inter-examiner reliability exhibited a wide range of values, some …

Intraoral Phaeohyphomycosis, Yeshwant B. Rawal, John R. Kalmar

School of Dentistry Faculty Research and Publications

Phaeohyphomycosis is an infection caused by pigment-producing saprophytic fungi. Systemic infections may occur in the immunocompromised patient. Infection in healthy individuals may result in subcutaneous abscess formation. Oral lesions appear to be rare. A case of intraoral phaeohyphomycosis presenting as a well-demarcated, painful nodule of the anterior hard palate in a 12-year-old healthy male is described. The mass was excised and the diagnosis was established following histopathologic examination of the tissue.

Etiology Of Noncarious Cervical Lesions, Caren M. Barnes

College of Dentistry: Faculty Publications

As the number of older adults in the United States continues to grow, this change in patient demographics will profoundly affect the practice of dental hygiene. Not only are there more older adults, but they are also retaining more of their natural teeth than ever before. The risk of alveolar bone loss; gingival recession, which can lead to exposed cervical and root areas of the teeth; and tooth wear all increase with age. The confluence of these factors raises the risk of noncarious cervical lesions (NCCLs).

The prevalence of NCCLs is growing, largely due to the rising numbers of older …

Expression And Localization Of Aquaporin‐1 In Temporomandibular Joint Disc With Internal Derangement, Carla Loreto, Concetta Galanti, Luis Eduardo Almeida, Rosalia Leonardi, Giuseppe Pannone, Giuseppe Musumeci, Maria Luisa Carnazza, Rosario Caltabiano

School of Dentistry Faculty Research and Publications

Background: Internal derangement is the most frequent arthropathy affecting the temporomandibular joint, where its commonest form is anterior disc displacement with or without reduction. Despite the frequency of the disorder, the biochemical features of displaced discs are still unclear.

Methods: We investigated the expression pattern and localization of aquaporin‐1, an important channel protein involved in plasma membrane water permeability, in patients with anterior disc displacement (both with and without reduction), with a view to assessing the characteristics of local tissue responses to the microenvironmental changes induced by abnormal mechanical loading of the displaced disc. Protein expression was studied by immunohistochemistry …

Titanium Nitride And Nitrogen Ion Implanted Coated Dental Materials, Youssef S. Al Jabbari, Jennifer Fehrman, Ashley C. Barnes, Angela M. Zapf, David W. Berzins, Spiros Zinelis

School of Dentistry Faculty Research and Publications

Titanium nitride and/or nitrogen ion implanted coated dental materials have been investigated since the mid-1980s and considered in various applications in dentistry such as implants, abutments, orthodontic wires, endodontic files, periodontal/oral hygiene instruments, and casting alloys for fixed restorations. Multiple methodologies have been employed to create the coatings, but detailed structural analysis of the coatings is generally lacking in the dental literature. Depending on application, the purpose of the coating is to provide increased surface hardness, abrasion/wear resistance, esthetics, and corrosion resistance, lower friction, as well as greater beneficial interaction with adjacent biological and material substrates. While many studies have …

Empowering The World Through Dentistry, Charles W. Vittitow

Mahurin Honors College Capstone Experience/Thesis Projects

Dentistry is a very specific trade that one develops after years of education and training. With this skill comes a great amount of power and opportunity to serve, and with great skill comes great responsibility. Many dentists have decided to answer the call of third world countries that lack proper health care and specifically dental care. They do this in a variety of ways from sending supplies, supporting a local clinic financially, or traveling to the country for a short-term trip where they provide dental care to as many patients as they are physically able to for 7 to 10 …

Post-Traumatic Apexogenesis Of Immature Non-Vital Permanent Incisors, Robia Ghafoor

Section of Dental-Oral Maxillofacial Surgery

Injury to an immature permanent tooth may result in cessation of dentin deposition and root maturation leaving an open root apex and thin dentinal walls that are prone to fracture. Endodontic treatment is often complicated and protracted with an uncertain prognosis frequently resulting in pre-mature tooth loss. There are several advantages of promoting apexogenesis in immature teeth with open apices. It encourages a longer and thicker root to develop thus decreasing the propensity of long term root fracture. This case report highlights the role of Hertwig root sheath and dental papilla in continued root formation of immature permanent tooth, even …

Dmft And Its Possible Determinants In The Honduran Population, Patrick T. Cooper

Honors Scholar Theses

Objectives: This study was designed to investigate the dental health status of several communities in Honduras in terms of the DMFT index (decayed missing and filled teeth). Specifically the study focused on comparisons of the Garifuna (a maroon community in Tela) with the people of San Jose, Copan, and others who traveled from other regions to come to a medical clinic. These results were also compared to other populations of developing and developed countries. Through looking at each participant’s DMFT score, many possible correlations to oral health were explored including region, age, gender, snacking, tobacco use, and oral hygiene. …

Remarkable Resilience Of Teeth (How Are Teeth So Brittle Yet So Resilient), Paul J. Constantino

Biological Sciences Faculty Research

Tooth enamel is inherently weak, with fracture toughness comparable with glass, yet it is remarkably resilient, surviving millions of functional contacts over a lifetime. We propose a microstructural mechanism of damage resistance, based on observations from ex situ loading of human and sea otter molars (teeth with strikingly similar structural features). Section views of the enamel implicate tufts, hypomineralized crack-like defects at the enamel–dentin junction, as primary fracture sources. We report a stabilization in the evolution of these defects, by ‘‘stress shielding’’ from neighbors, by inhibition of ensuing crack extension from prism interweaving (decussation), and by self-healing. These factors, coupled …
