Polishing Esthetic Restorative Materiai, Caren M. Barnes

College of Dentistry: Faculty Publications

When esthetic dental restorations are encountered during charting, they should be included in the treatment plan for the specific polishing procedures that are required. If the brand and type of esthetic restoration are known through the patient chart, the polishing procedures and products used should be those recommended by the manufacturer. If not possible, alternative polishing procedures should be used. A cleaning agent containing feldspar and rubber polishing cup can be used on all esthetic restorative materials with no chance of damage to the surface characterization.

The principles for polishing esthetic restorations are the same as for natural teeth. If …

Synthesis Of Urethane Acrylate Macromer From Palm Oil-Based Polyol And Its Application As A Resin For Dental Composite., Fadheel A. A. Alsanabani

Student Works (2010-2019)

A slightly branched urethane acrylate macromer (UAM) was synthesized by reacting palm oil-based polyol with excess amounts of polymeric methylene diphenyl diisocyanate (MDI) to form urethane prepolymer, then reacted with 2-hydroxyethyl methacrylate (HEMA) and FT-IR spectroscopy confirmed the urethane and grafted acrylate groups. 0.2% by weight of camphoroquinone (CQ) and 0.8% by weight of ethyl-4-N,N-dimethylamino-benzoate (4EDMAB) by weight were added to render the experimental resins light-curable. Their viscosity, percentage of degree of conversion (%DC) and cross-linking density (CLD), percentage of volumetric polymerization shrinkage (%VPS), water sorption and solubility, flexural strength, modulus of elasticity and toughness were determined and compared to …

Diversity, Commonality, And Stability Of Mutans Streptococci In High Caries Risk Children, Kyounga Cheon

All ETDs from UAB

Mutans streptococci (MS), Streptococcus mutans and Streptococcus sobrinus are associated with the initiation of dental caries in humans. Initially, a single S. mutans genotype has been shown to colonize primary molars soon after eruption. More genotypes can be acquired with age and further dental development. Current methods used to genotype isolates from an individual have not systematically determined the minimum number required to demonstrate an individual's genetic diversity. The purpose of this study was to determine the optimum number of oral isolates of MS (i.e., from plaque samples) to genotype in order to demonstrate diversity. This study also initiated a …

Genotyping Of Streptococcus Mutans Using Multilocus Sequence Typing, Stephanie Momeni

All ETDs from UAB

ABSTRACT The role of Streptococcus mutans has been extensively studied using a variety of genotyping techniques. Repetitive extragenic palindromic polymerase chain reaction (rep-PCR) is an effective tool for screening large-scale epidemiological studies with high discriminatory power and reproducibility. For this study, multilocus sequence typing (MLST) analysis is used to evaluate genotypes previously identified as unique using rep-PCR. Twenty-two unique S. mutans rep- PCR genotypes were selected from a longitudinal study. Four additional isolates were selected from each genotype group of the 6 most commonly occurring genotypes (n=30) for further analysis. Real-time PCR was performed using eight housekeeping S. mutans gene …

The Quantification Of Tooth Displacement, Thomas W. Radmer, L Thomas Johnson, Mingan Yang, Thomas Wirtz

School of Dentistry Faculty Research and Publications

By using reference points from a single pixel marker placed at the center point of the cuspid teeth and the center point on each of the incisor teeth, a polynomial curve was generated as a native curve for each dental arch studied. The polynomial curve generated from actual tooth position in each arch provides the forensic odontologist with another reference point that is quantifiable. The study represents that individual characteristics, such as tooth displacement, can be quantified in a simple, reliable, and repeatable format.

Collagenous Myofibroblastic Tumor Of The Mandible: Case Report Of A Unique Locally Aggressive Neoplasm, Jason W. Nash, Amy C. Hessel, Nadarajah Vigneswaran, Adel K. El-Naggar

Faculty, Staff and Student Publications

We report a locally aggressive collagenous myofibroblastic neoplasm of the mandible in an 18-year-old male. Clinically, the lesion presented with rapid growth and irregular mandibular bone destruction. Grossly, the tumor was 10 cm in greatest dimension, light-tan, firm, and involving the posterior one-thirds of the body and inferior half of the left mandibular ramus. Histologically, the lesion was composed of a loose spindle cell proliferation interspersed with periodic dense bands of collagen. The spindle cells reacted positively to smooth muscle actin, calponin, and focally to desmin and were negative for S-100, pan-cytokeratin, CD99, CD34 and caldesmon, supporting myofibroblastic derivation. At …

Pulp Polyp Associated With A Natal Tooth: Case Report, Brian D. Hodgson, Rodney Vergotine, Lance Lambert

School of Dentistry Faculty Research and Publications

Natal teeth are an infrequent occurrence at birth. Often these teeth are extracted because they are very mobile and pose a risk of aspiration. This is a rare case in which a natal tooth was extracted by the pediatrician with his fingers. A root fragment remained and out of this developed a large pulp polyp. This relationship has not been previously reported.

Adding Dental Therapists To The Health Care Team To Improve Access To Oral Health Care For Children, David A. Nash

Oral Health Science Faculty Publications

Oral Health in America: A Report of the Surgeon General, and the subsequent National Call to Action to Promote Oral Health, contributed significantly to raising awareness regarding the lack of access to oral health care by many Americans, especially minority and low-income populations, with resulting disparities in oral health. The problem is particularly acute among children. The current dental workforce in the United States is inadequate to meet the oral health care needs of children. It is inadequate in terms of numbers of dentists, as well as their geographic distribution, ethnicity, education, and practice orientation. Dental therapists, paraprofessionals …

Quantification Of The Individual Characteristics Of The Human Dentition, L Thomas Johnson, Thomas W. Radmer, Thomas S. Wirtz, Nicholas M. Pajewski, David E. Cadle, James Brozek, Daniel D. Blinka

School of Dentistry Faculty Research and Publications

The considerations for admissibility suggested by the Daubert trilogy challenge forensic experts to provide scientific support for opinion testimony. The defense bar has questioned the reliability of bitemark analysis. Under an award from the U. S. Department of Justice, via the Midwest Forensic Resource Center, a two-year feasibility study was undertaken to quantify six dental characteristics. Using two computer programs, the exemplars of 419 volunteers were digitally scanned, characteristics were measured, and frequency was calculated. The study demonstrates that there were outliers or rare dental characteristics in measurements. An analysis of the intra-observer and inter-observer consistency demonstrated a high degree …

Killing Of Treponema Denticola By Mouse Peritoneal Macrophages, P. Gaibani, C. Vocale, S. Ambretti, F. Cavrini, Jacques Izard, L. Miragliotta, M. T. Pellegrino, V. Sambri

Department of Food Science and Technology: Faculty Publications

Treponema denticola has been identified as an important cause of periodontal disease and hypothesized to be involved in extra-oral infections. The objective of this study was to investigate the role of T. denticola cell length and motility during mouse peritoneal macrophages in vitro uptake. Macrophages, incubated under aerobic and anaerobic conditions, produced a similar amount of TNF-α when stimulated with Escherichia coli LPS. The uptake of FlgE- and CfpA-deficient mutants of T. denticola was significantly increased compared with the wild-type strain, due to cell size or lack of motility. Opsonization with specific antibodies considerably improved the treponemes’ uptake. …
