This work focused on the process of bone repair of defects in standardized calvaria of Wistar rats treated with biphasic calcium phosphate (BCP), mineral trioxide aggregate (MTA), or a combination of the two. Eighty Wistar rats were divided into four treatment groups and were examined at 2 and 8 weeks. A surgical defect was created in the calvaria using a 6-mm diameter trephine drill. The cavity was treated with BCP, MTA, or BCP + MTA; untreated rats with clot formation served as controls. Samples were evaluated histologically and by immunohistochemical staining for areas of new osteoid tissue and new bone tissue ...


The Purpose And Value For Students Of Pbl Groups For Learning, Vicki J. Skinner, Annette Braunack-Mayer, Tracey A. Winning 2015 University of Adelaide

The Purpose And Value For Students Of Pbl Groups For Learning, Vicki J. Skinner, Annette Braunack-Mayer, Tracey A. Winning

Interdisciplinary Journal of Problem-Based Learning

Groups are central to problem-based learning (PBL) and educational and professional outcomes relevant to clinical education. However, PBL groups in practice may differ from theoretical conceptions of groups. Therefore, this study explored students’ understandings of the purpose and value of PBL groups for their learning. We conducted a naturalistic study with novice (first-year) students at two dental schools (Australia, Ireland), using observation and interviews analyzed thematically. Students constructed PBL learning as individual knowledge gain, and group purpose as information gathering and exchange; few students acknowledged the learning potential of group processes. Group value depended on assessment and curriculum context. Findings ...

School of Dentistry Faculty Research and Publications

Complex odontoma (CO) is considered one of the most common odontogenic lesions, composed by a miscellaneous of dental tissue such as enamel, dentin, pulp and sometimes cementum. They may interfere with the eruption of an associated tooth, being more prevalent in the posterior mandible. CO has been rarely reported as erupted, being considered an intraosseous lesion. This is a case report of a 17-year-old male with a benign fibro-osseous lesion consistent with CO that was located at the left second molar region, above the crown of the impacted mandibular second molar tooth. The lesion was surgically removed, and the tooth ...


An Assessment Of What Factors Affect The Average Number Of Caries Seen Per Visit Among Children Visiting A Mobile Dental Unit In South Central Kentucky, Breion Douglas 2014 Western Kentucky University

An Assessment Of What Factors Affect The Average Number Of Caries Seen Per Visit Among Children Visiting A Mobile Dental Unit In South Central Kentucky, Breion Douglas

Honors College Capstone Experience/Thesis Projects

Background: Dental caries is the single most common chronic childhood disease in Kentucky affecting 20% of preschoolers, 50% of second graders, and 75% of 15 year olds. Dental caries, also known as tooth decay, occurs when bacteria from salivary glands produce an acid to breakdown food. If this acid is not cleaned off the teeth, it can destroy the tooth enamel. Dental problems can be linked to the inability to pay for dental care (i.e. insurance), limited access to dental providers, and parental inability to take their children to dentists. To help address the issue with tooth decay seen ...


A Marginalized Zero-Inflated Negative Binomial Regression Model With Overall Exposure Effects, John S. Preisser, Kalyan Das, D. Leann Long, John W. Stamm 2014 University of North Carolina at Chapel Hill

A Marginalized Zero-Inflated Negative Binomial Regression Model With Overall Exposure Effects, John S. Preisser, Kalyan Das, D. Leann Long, John W. Stamm

The University of North Carolina at Chapel Hill Department of Biostatistics Technical Report Series

The zero-inflated negative binomial regression model (ZINB) is often employed in diverse fields such as dentistry, health care utilization, highway safety, and medicine, to examine relationships between exposures of interest and overdispersed count outcomes exhibiting many zeros. The regression coefficients of ZINB have latent class interpretations for a susceptible subpopulation at risk for the disease/condition under study with counts generated from a negative binomial distribution and for a non-susceptible subpopulation that provides only zero counts. The ZINB parameters, however, are not well-suited for estimating overall exposure effects, specifically, in quantifying the effect of an explanatory variable in the overall ...
