School of Dentistry Faculty Publications

Rubber dam isolation is crucial in providing sterility and a controlled environment when performing root canal therapy. Rubber dam clamps have been controversial due to their rigidity and composition, which is thought to cause damage to zirconia full coverage crowns. This study evaluated three types of zirconia crowns anterior 5Y, premolar 4Y, and molar 3Y to assess their resistance to damage from rubber dam clamps. Of the 30 total zirconia crowns that were tested for damage following the usage of rubber dam clamps, no fractures or chips were observed. There was no significant difference between the negative control group, and …

Evaluation Of Different Resin-Based Barriers In Reducing Microleakage In Restoratively Compromised Posterior Teeth During Rubber Dam Isolation: An Ex Vivo Study, Carolina Becerra, Albert F. Mcmullen Iii, Joon Koh, Thomas E. Lallier

School of Dentistry Faculty Publications

Introduction: The rubber dam has been a standard in endodontic practice for over 140 years, providing critical isolation to prevent microbial contamination during root canal therapy. However, studies indicate that microleakage between the rubber dam and tooth structure may still occur, potentially leading to bacterial infiltration. Various resin-based barriers have been introduced to enhance isolation and minimize leakage. This study aimed to evaluate the efficacy of four resin-based barriers in reducing microleakage during endodontic procedures. Methods: Forty extracted human mandibular molars were selected, stored in distilled water, and standardized for experimental conditions. Standard endodontic access was created, and the mesiobuccal …

Comparing Gutta Percha Backfill Leakage Over Multiple Heating Cycles, Hannah Battle, Thomas E. Lallier, Landon Boenke, Albert F. Mcmullen Iii

School of Dentistry Faculty Publications

Introduction: Warm vertical compaction of gutta-percha is a commonly used obturation technique due to the material’s thermoplastic properties. However, gutta-percha in backfill systems is often heated, cooled, and reheated multiple times before use, potentially altering its physical properties. This study investigated whether repeated heat cycling affects the sealing ability of gutta-percha, as measured by coronal dye leakage. Methods: Forty extracted single-rooted human teeth were cleaned, shaped, and randomly divided into four groups (n = 10) based on the number of heating cycles the gutta-percha underwent prior to obturation: Group A (1 cycle), Group B (3 cycles), Group C (5 cycles), …

Carbon Footprint Of Inhaled Anesthetics – Do The Risks Outweigh The Benefits?, Liam Kerrick, Joseph Moschella

Rowan-Virtua Research Day

Global warming presents many challenges to the healthcare system. Not only does the increasing global temperature have detrimental health effects itself, but the healthcare sector is also a huge contributor to global warming. One big contributor to global warming is the use of inhaled anesthetics, which possess global warming potentials up to 2,000 times greater than carbon dioxide. Recent proposals, such as a prospective ban of desflurane in 2026 by the European Commission, demonstrate the need to reevaluate many of the common practices within anesthesiology. This review looks to investigate the environmental impact, cost, and clinical efficacy of various anesthetic …

Pseudomonas Aeruginosa Exoenzyme Y Enzymatic Activity Inhibits Exoenzyme S-Induced Caspase Activation But Not Cytotoxicity In Pulmonary Microvascular Endothelial Cells, Connor Holm

Honors Theses

Pseudomonas aeruginosa (P. aeruginosa) is the most common cause of ventilator-associated pneumonia in intensive care unit patients. P. aeruginosa utilizes a type III secretion system that injects exoenzymes U, S, T, and/or Y into the host cell cytosol. A majority of clinically isolated P. aeruginosa strains express ExoY often in combination with ExoU and ExoT, or ExoS and ExoT. Host signaling mechanisms in response to intoxication with individual exoenzymes have been extensively studied, yet little is known about host cell response to co-intoxication. In this study, pulmonary microvascular endothelial cells (PMVECs) were infected with P. aeruginosa strains expressing different combinations …

Serendipitous Supernormality, Behzad B. Pavri, Eitan Frankel

Division of Cardiology Faculty Papers

We describe a patient who underwent AV node modification to create complete heart block in the setting of incessant, ablation-and-drug-refractory, symptomatic atypical atrial flutter. His dual chamber defibrillator (previously implanted for resuscitated cardiac arrest) was programmed to the VVIR mode at a faster pacing rate of 85 bpm. Serendipitously, this rate was an almost exact factorial of his flutter rate of 250-260 bpm. This resulted in every 6th flutter wave falling in the supernormal period, resulting in fixed-coupled supraventricular bigeminy and trigeminy in the setting of complete heart block. Reprogramming the pacing rate to 75 bpm abolished bigeminy and trigeminy.
