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 ...

Odontogenic Keratocyst Mandible An Interesting Case Report And Literature Review, Balasubramanian Thiagarajan, Geetha Ramamoorthy 2014 Stanley Medical College

Odontogenic Keratocyst Mandible An Interesting Case Report And Literature Review, Balasubramanian Thiagarajan, Geetha Ramamoorthy

Balasubramanian Thiagarajan

The term odontogenic keratocyst was first described by Philipsen in 1956. This cyst actually arises from the cell rests of dental lamina. It can occur anywhere in the jaw but is commonly seen in the posterior part of the mandible. Since the clinical features and radiological appearance are not characteristic this condition is commonly misdiagnosed. This is more so when the lesion is related to the nonvital tooth. Odontogenic keratocyst has been rechristened as keratocystic odontogenic tumor by WHO working group in 2005. This was necessitated to differentiate this lesion from its orthokeratinizing variant which is currently considered as odontogenic ...
