Benign Myoepithelioma Of The Soft Palate: An Unusual Clinical Entity, Marianna Guadalupe Mireles, Angelica Julián, Fabiola Salgado-Chavarría, Guillermo Manuel González

Faculty, Staff and Students Publications

Myoepitheliomas are rare benign tumours that affect the exocrine glands and are sporadically located in the salivary glands. The most common location of myoepithelioma in the oral cavity is the parotid gland and it is seldom encountered in the palate. The diagnosis of this entity is challenging since its clinical presentation may resemble those of more common neoplasms, rendering a complex histopathological diagnosis. The aim of the present case report is to describe an unusual case of myoepithelioma of the soft palate in a male patient, which developed as an asymptomatic, slowly growing mass. The tumour was assessed with histopathological …

Strategies For Treatment Of Bilateral Impacted High Canine–Lateral Incisor Transposition: A Stepwise Approach, Yun-Yun Wu, Fu-Hui Tsai, Jui-Hsien Yang

Taiwanese Journal of Orthodontics

To achieve a satisfactory outcome for transposed impacted teeth, the esthetic assessment and functional rehabilitation should be considered from both the orthodontic and periodontic perspective. In this case, a stepwise approach was used for both surgical uncovering and orthodontic treatment to manage the soft and hard tissue of transposed high canine. The case involved a girl aged 11 years and 7 months with bilateral high impacted canine–lateral incisor transposition. The impacted canines were first uncovered with the closed eruption technique and then moved horizontally to a normal sequence in the arch. Apically repositioned flap surgery was then performed, and the …

Taiwanese Journal of Orthodontics

Maxillary canine is an essential part of teeth for smile esthetic and function. Orthodontic treatment for patient with impacted maxillary canine is considered to be more complex and require good biomechanical control during traction. This case report describes an orthodontic treatment of a 17-year old female patient with unilateral maxillary canine impaction on the left side. Orthodontic traction was used to guide the canine into normal occlusion. The orthodontic treatment had been completed within 19 months and successfully obtained favourable esthetic and stable occlusion.

Compare Two Methods Of Dental Arch Length Measurements On Digital Dental Models, Ying-Chen Chen, Carol Yi-Hsuan Chen, Ellen Wen-Ching Ko

Taiwanese Journal of Orthodontics

Purpose: Accurate space discrepancy evaluation is important in treatment planning. Straight-line segments and brass wire method are the most common methods in arch length assessment. However, using segments causes underestimation, while more reliable brass wire method shows lower reproducibility. The aim of our study is (1) to compare the difference between conventional segmental distance method (SD) and a new method, ideal arch form (IA), and (2) to assess the reproducibility and reliability of two methods by means of digital models. Materials and methods: Thirty sets of digital dental models presented full permanent dentition and Angle’s Class III malocclusion were included. …

Streptococcus Mutans Lacking Sufcdsub Is Viable, But Displays Major Defects In Growth, Stress Tolerance Responses And Biofilm Formation, Kassapa Ellepola, Xiaochang Huang, Ryan P. Riley, Jacob P. Bitoun, Zezhang Tom Wen

School of Dentistry Faculty Publications

Streptococcus mutans appears to possess a sole iron-sulfur (Fe-S) cluster biosynthesis system encoded by the sufCDSUB cluster. This study was designed to examine the role of sufCDSUB in S. mutans physiology. Allelic exchange mutants deficient of the whole sufCDSUB cluster and in individual genes were constructed. Compared to the wild-type, UA159, the sufCDSUB-deficient mutant, Δsuf::kanr, had a significantly reduced growth rate, especially in medium with the absence of isoleucine, leucine or glutamate/glutamine, amino acids that require Fe-S clusters for biosynthesis and when grown with medium adjusted to pH 6.0 and under oxidative and nitrosative stress conditions. Relative to UA159, Δsuf::kanr …

Molecular Screening And Analysis Reveal Novel Oral Site-Specific Locations For The Cariogenic Pathogen Scardovia Wiggsiae, Steven Mcdaniel, Jaydene Mcdaniel, Katherine M. Howard, Karl Kingsley

Dental Medicine Faculty Research

Introduction: Scardovia wiggsiae (SW) is a newly identified cariogenic pathogen associated with severe early childhood caries and oral disease. New studies have confirmed the presence of this organism among clinical samples from both pediatric and adult patients. However, the recent discovery of this organism has left researchers with only limited information available regarding the prevalence of this organism—and virtually no information regarding oral site-specific locations. Based upon this lack of information, the overall objective of this study was to perform an oral site-specific analysis of SW prevalence from clinical samples. Methods: Using an approved human subjects protocol, samples (n = …

Assessment Of Microrna (Mir)-365 Effects On Oral Squamous Carcinoma Cell Line Phenotypes, Jeffery Coon, Karl Kingsley

Dental Medicine Faculty Research

miR-365 is a microRNA that regulates transcription and has been demonstrated to promote oncogenesis and metastasis in some cancers while suppressing these effects in others. Virtually no information is known about the presence or function of miR-365 in oral cancers. Based upon this information, the primary goal of this project was to evaluate the expression of miR-365 in existing oral cancer cell lines. Five commercially available oral cancer cell lines (SCC4, SCC9, SCC15, SCC25, and CAL27) were obtained and cultured. RNA was then screened by PCR using primers specific for miR-365, as well as matrix metalloproteinase (MMP-2) and a downstream …

Microbial Screening Reveals Oral Site-Specific Locations Of The Periodontal Pathogen Selenomonas Noxia, Jaydene Mcdaniel, Steven Mcdaniel, Beanca Jhanine Samiano, Matthew Marrujo, Karl Kingsley, Katherine M. Howard

Dental Medicine Faculty Research

Introduction: Selenomonas noxia (SN) is an important periodontal pathogen, associated with gingivitis and periodontitis. Many studies have found associations between SN and indicators of poor health outcomes, such as smoking, low socioeconomic status and obesity. However, less is known about the prevalence of this organism and more specifically about other oral site-specific locations that may harbor this organism. Methods: Using an existing patient repository (n = 47) of DNA isolated from saliva and other oral sites (n = 235), including the dorsum of the tongue, lower lingual incisor, upper buccal molar and gingival crevicular fluid (GCF), molecular screening for SN …

Immunotherapies For Neurodegenerative Diseases, Ibrahim Mortada, Raymond Farah, Sanaa Nabha, David M. Ojcius, Youssef Fares, Wassim Y. Almawi, Najwane S. Sadier

All Dugoni School of Dentistry Faculty Articles

The current treatments for neurodegenerative diseases are mostly symptomatic without affecting the underlying cause of disease. Emerging evidence supports a potential role for immunotherapy in the management of disease progression. Numerous reports raise the exciting prospect that either the immune system or its derivative components could be harnessed to fight the misfolded and aggregated proteins that accumulate in several neurodegenerative diseases. Passive and active vaccinations using monoclonal antibodies and specific antigens that induce adaptive immune responses are currently under evaluation for their potential use in the development of immunotherapies. In this review, we aim to shed light on prominent immunotherapeutic …

Longitudinal Curricular Assessment Of Knowledge And Awareness Of Intimate Partner Violence Among First-Year Dental Students, Charles Buchanan, Karl Kingsley, Rhonda J. Everett

Dental Medicine Faculty Research

Background: Intimate partner violence (IPV) has previously been recognized as a major public health issue. Oral healthcare providers, such as dentists, are crucial to the screening and identifying of individuals experiencing IPV, since most injuries occur in the head and neck region. A lack of knowledge and awareness regarding teaching and learning about IPV in dental school curricula has been identified. Based upon the overall lack of knowledge, the objective of this study was to conduct a longitudinal assessment of knowledge, awareness, and beliefs regarding IPV among dental students in their first year of education.

Does Alcohol Consumption Protect Against Late Dental Implant Failures?, Brian R. Carr, William J. Boggess, John F. Coburn, Peter Rekawek, Sung Kiang Chuang, Neeraj Panchal, Brian P. Ford

School of Dentistry Faculty Publications

Purpose: Social factors have been implicated in the development of peri-implant pathologies, including implant failure. This study aims to investigate whether alcohol consumption affects late dental implant failures. Methods: A retrospective cohort study evaluated implants placed between 2006 and 2012 at the Philadelphia Veterans Affairs Medical Center. The primary predictor variable was alcohol consumption, measured as nonconsumption and mild, moderate, and heavy consumption. The primary outcome variable was late dental implant failure. Univariate, bivariate, and multivariate statistics were applied, with P <.05 used to define statistical significance. Results: Our cohort consisted of 103 patients and 295 implants with a 5-year minimum follow-up. Most patients were male (93%) with an average age of 60 at the time of implant placement. Late implant failure was associated with 30 implants. Compared to nonconsumption, mild consumption was associated with a 75% decrease in late implant failure (P =.0494), moderate consumption was associated with a 60% decrease (P =.3826), and heavy consumption was associated with a 200% increase (P <.1782). Compared to mild consumption, heavy consumption was associated with an 847% increase in late failure (P =.0135). Conclusions: Results from this retrospective cohort analysis suggest that mild alcohol consumption is associated with a decrease in late dental implant failures.
