Background

Syphilis is a sexually-transmitted infectious disease caused by Treponema pallidum. Cases of primary and secondary syphilis are on the rise in the United States, with a 14.4% increase in new cases noted from 2017 to 2018 and an escalation of 71% between the years 2014 and 2018. Fulfilling its nickname of “the great imitator,” oral manifestations of syphilis may mimic a variety of infectious, neoplastic, or immune-mediated processes, both clinically and histopathologically. This large spectrum of appearances can create a diagnostic challenge to the clinician and/or pathologist, leading to delay in diagnosis or misdiagnosis.

The Case For Shifting Clinical Dentistry Toward Regenerative Biological Treatment Using Stem Cells: A Life-Changing Impact On The Profession’S Future, Merna Gress

English Language Institute

The conventional current procedures targeting the periodontal treatment for the diseased teeth and gums are based on arresting the destruction of these supporting structures and limiting the number of bacteria present. However, an ideal treatment would be regenerative in nature and should be accompanied with the reconstruction of these periodontal tissues back to normal. The application of Regenerative Dentistry is achieved through using the concept of cell and molecular biology to empower dental treatments that target a repair process for oral tissues instead of utilizing synthetic materials. One of the main applications of this concept is adult tissue-derived Mesenchymal Stem …

Objective Physiological Measures Of Lingual And Jaw Function In Healthy Individuals And Individuals With Dysphagia Due To Neurodegenerative Diseases, Megan E. Cuellar, Elizabeth Oommen

Faculty Research, Scholarly, and Creative Activity

Swallowing is a neuromuscular process that involves a complex sequence of sensorimotor events, which are executed to efficiently and safely transport food and liquid from the mouth to the stomach. Safe oropharyngeal swallowing involves the activation, modulation, and coordination of oral, pharyngeal, laryngeal, and esophageal structures and musculature. Impaired or atypical patterns of swallowing are considered characteristic of a swallowing disorder, otherwise referred to as dysphagia, and affect the performance of all stages, i.e., oral preparatory, oral transit, pharyngeal, and esophageal. Lingual and jaw musculature play critical roles in mediating swallowing function, particularly during the oral preparatory and oral transit …

Oral Health Science Faculty Publications

BACKGROUND: The purpose of this study was to identify pretreatment factors associated with the stability of early class III treatment, since most orthodontists start the treatment with their uncertain hypotheses and/or predictions. Subjects consisted of 75 patients with a class III skeletal relationship (ANB < 2° and overjet < 0 mm) who had been consecutively treated with rapid maxillary expansion and facemask and followed until their second phase treatment. The patients were divided into two groups according to whether they showed relapse in follow-up. The stable group maintained their positive overjet (n = 55), and the unstable group experienced relapse with a zero or negative overjet (n = 20). Two general, three dental, and 13 cephalometric pretreatment factors were investigated to determine which factors were associated with stability.

RESULTS: Sex, pretreatment age, and anteroposterior functional shift, which were hypothesized as associated factors, were not related to …
