Space Maintenance In The Primary And Mixed Dentitions, Giovana Anovazzi Medeiros Dds, Msc, Phd, Chia-En Tsai Dds, James R. Boynton Dds, Ms

The Journal of the Michigan Dental Association

Primary teeth serve many critical functions in the growing child: they allow for proper chewing function for appropriate diet and nutrition, help in speech production and development, promote self-esteem, and importantly preserve space for eruption of the succedaneous permanent dentition. Premature loss of a primary molar can cause a loss of arch perimeter and negatively impact the normal eruption path of premolars. Space maintenance is an approach to minimize or prevent untoward consequences after unavoidable loss of a primary molar. Several types of space maintainers can be used to preserve arch length, including fixed unilateral space maintainers, such as the …

Probing The Porphyromonas Gingivalis Nitrosative Stress Response Network, Alexandra Galina

Theses and Dissertations

Objective: To persist in the oral cavity, the perio-pathogen Porphyromonas gingivalis must have an efficient nitrosative stress response mechanism. To better understand how P. gingivalis responds to nitrite (NO₂^-) we must determine what genes are involved in the nitrosative stress response network.

Methods: Through genomic screening, a list of genes was generated that were hypothesized to be part of the nitrosative stress response network and believed to be involved in nitrate/nitrite metabolism or redox state of the cells. Protein coding regions were replaced with the ermF sequence by allelic exchange mutagenesis. 15 mutants were created …

A Flash Of Inspiration: Enhancing Dental Student Drug Recognition, Benjamin D. Zeitlin

All Dugoni School of Dentistry Faculty Articles

Students preparing for exams often retain the complexities of a subject but instant recognition and recall is something that, for most, takes time and consistent, repeated study to establish. This can happen through well-managed spaced learning (iterative study) prior to examination; given the preponderance of massed study (cramming for a subject),1 however, many students require long-term exposure in the clinic to patients’ medical histories to achieve instant recall. Understanding the applied pharmacology of common drugs is a current American Dental Association accreditation standard. Ideally, dental students should demonstrate a consistent level of basic drug recognition and the ability to retrieve …
