Pink Tooth Of Mummery In The Maxillary Left Canine After Fixed Partial Denture (Fpd) Preparation, Eger V. Korolevsky, Takashi Komabayashi, Denise Foran

Dental Medicine Faculty Publications

Pink tooth of Mummery is typically found after trauma. However, this case report describes an unusual occurrence of pink tooth in a 67-year-old Caucasian male after fixed partial denture (FPD) tooth preparation. Pink tooth in this case may be due to one or more factors: tooth reduction and heat generation during tooth preparation; heat generation during polymerization of provisional material; and hyperocclusion of a provisional FPD. This case highlights the importance of choosing the appropriate materials and techniques to avoid pulpal complications after dental prosthesis work.

The Role Of Periodontal Disease In Lymphatic Function, Kristen Carlisle, Hanna Marie, Haley Taylor

Dental Hygiene Student Research Posters

Research poster addressing the question: Does periodontal disease affect lymphatic function? Gingival lymphatic vessels drain interstitial fluid and transport immune cells to lymph nodes but despite this, it is unknown how the lymphatic system impacts periodontal disease in humans. In light of this, studies have been observed on animals with the vascular endothelial growth factor C (VEGFC), a growth factor known to be increased in periodontal patients. VEGFC is involved in lymphatic hyperplasia and lymphangiogenesis, the proliferation of lymphatic endothelial cells. This growth factor is believed to affect gingival lymphatic function in periodontitis patients. When reviewing the literature, it is …

Gene Therapy In Rheumatoid Arthritis: Strategies To Select Therapeutic Genes, Mahdi Zavvar, Sara Assadiasl, Narjes Soleimanifar, Fatemeh Dadgar Pakdel, Kamal Abdolmohammadi, Yousef Fatahi, Mohsen Abdolmaleki, Hamed Baghdadi, Lobat Tayebi, Mohammad Hossein Nicknam

School of Dentistry Faculty Research and Publications

Significant advances have been achieved in recent years to ameliorate rheumatoid arthritis (RA) in animal models using gene therapy approaches rather than biological treatments. Although biological agents serve as antirheumatic drugs with suppressing proinflammatory cytokine activities, they are usually accompanied by systemic immune suppression resulting from continuous or high systemic dose injections of biological agents. Therefore, gene transfer approaches have opened an interesting perspective to deliver one or multiple genes in a target‐specific or inducible manner for the sustained intra‐articular expression of therapeutic products. Accordingly, many studies have focused on gene transferring methods in animal models by using one of …

Breast and prostate cancers are common types of cancers with various strategies, such as chemotherapy and radiotherapy, for their therapy. Since these methods have undesired side effects and poor target affinity, neoteric strategies—known as aptamer-based smart drug delivery systems (SDDSs)—have been developed in recent years to overcome the obstacles of current treatment, and investigated for a clinical trial. The high affinity and versatility of aptamers for binding to the corresponding targets make them highly noticeable agents in the drug delivery domains. In addition to their exceptional benefits, aptamers are able to overcome tumor resistance because of their high selectivity and …

Medical Dental Device: Biogeneric Implant Prototype, Ibeth Erazo, Aneeza Hussain, Renata Budny, Gaffar Gailani

Publications and Research

Teeth are lost due to tooth decay, injury, disease, or other causes. Today, dental implants extend the range of care to a variety of patients undergoing necessary prosthodontic rehabilitation. If the benefits of such treatments are to be maximized, then implants must be selected on logical basis and placed within the context of the full range of treatment modalities. However, modern dental implant systems are based on multiple components often leading to micro-movements which cause stress on the bone or bacterial infections, both of which compromise the success of osseointegration and consequently jeopardize the whole implant adaptation. Thus, a new …
