Abstract:

Macrophages play a fundamental role in driving both inflammatory and immunosuppressive conditions of the oral mucosa. Periodontitis, a chronic inflammatory condition affecting the supporting structures of the teeth, is widely prevalent, affecting a large proportion of the global population, and has been linked to the development of systemic inflammatory diseases. Oral squamous cell carcinoma (OSCC) is placed sixth in the WHO rankings of cancer incidence worldwide, and despite continuing research into underlying mechanisms, incidence is on the rise. Aberrant macrophage function has been implica

Abstract:

An exciting alternative to the current methods for bone regeneration is osseous tissue engineering. One such method focuses on enhancement of osteoblast differentiation through rotary cell culture techniques. The response of osteoblast aggregates to periodontal microorganisms and their by-products will ultimately be important in their success as a method of bone regeneration. In this study, I hypothesize that human embryonic palatal mesenchymal (HEPM, ATCC 1486) pre-osteoblast cells produce different cytokine responses depending upon whether they are grown in a 2-dimensional tissue culture fla

Abstract:

Objectives: Tooth extraction initiates a cascade of biological events leading to the reduction of alveolar ridge volume. Alveolar ridge preservation (ARP) is a surgical treatment which aims at minimizing hard and soft tissue changes following tooth extraction. Several techniques and materials have been studied and used clinically in ARP. The selection of the biomaterials used for this technique is determined by several factors, such as features of the extraction site, inherent biomaterial properties and handling preferences by the surgeon, among others. The purpose of this study was to evaluat

Abstract:

Long-chain bases (sphingosine, dihydrosphingosine, and phytosphingosine) are present in the oral cavity and have potent antimicrobial activity against oral pathogens. However, little is known about their cytotoxicity for oral cells, an important step in considering their potential as future antimicrobial agents for oral infections. In this study, primary oral keratinocytes, primary oral fibroblasts, dendritic cells, and oral squamous cell carcinoma cells were exposed to 10.0-640.0 µM long-chain bases and glycerol monolaurate (GML) in cell culture medium containing resazurin (e.g., Alamar Blue,

Abstract:

Objectives: Extraction of a tooth leads to a series of healing events that are intimately associated with dimensional changes in the alveolar ridge that typically result in a net volume loss. Previous studies have evaluated the extent and pattern of those resorptive changes, however it remains challenging to predict the degree of change that will occur, as numerous local and systemic factors may play a role in the biologic events that follow tooth extraction. The purpose of this study was to assess the role that phenotypic characteristics of the periodontium play in the alveolar ridge remodeli

Bisphosphonates are non-metabolized compounds with high affinity for bone mineral hydroxyapatite. These compounds are used in diagnosis and treatment of malignancies metastatic to bone.

Biofilm accounts for 65%-80% of microbial infections in humans. Considerable evidence links biofilm formation to oral disease and consequently systemic infections. Eradication of biofilm-associated infections is important. Streptococcus sanguinis, a Gram-positive bacterium, is one of the most abundant species in oral biofilm. It contributes to biofilm development in oral cavities and is one of the recognized causes of infective endocarditis. To study and identify biofilm genes in S. sanguinis, biofilm formation of 51 mutants was compared with the wild type SK36 strain using crystal violet (CV)

Abstract:

>Magister Scientiae - MSc<br>Periapical lesions are fairly common pathology associated with the apex of a non-vital tooth. Some chronic lesions develop without an acute phase with no recollection of previous symptoms. It is known that maxillary odontogenic infections can breach the sinus floor with succeeding complications. Pantomography, a widespread conventional radiographic technique, provides a generalized view of the maxillofacial region. Advanced modalities like CBCT may facilitate in navigating complex anatomy, which would otherwise be obscured.

Abstract:

Research suggests that speech and language disorders are among the most prevalent childhood disabilities in many countries. Identification and intervention for children with communication disorders are sought at an early stage, to avoid the consequences of untreated childhood speech and language problems that can lead to academic underachievement and even persist into adulthood. However, no study has been reported on the prevalence of speech and language disorders in the general population in Cameroon. Despite the published literature on the national burden of disease suggesting that a signifi

Abstract:

The facultative anaerobe, Escherichia coli and the obligate anaerobe, Porphyromonas gingivalis are two bacteria that reside in our body. Although they reside in separate environments, they are both subject to hydrogen peroxide stress and have mechanisms to regulate the stress. OxyR is the primary transcriptional regulator/sensor of oxidative stress response caused by hydrogen peroxide. OxyR in P. gingivalis is not well-characterized compared to OxyR in E. coli. We sought to characterize and compare the two forms of OxyR in order to gain a better understanding of the protein. We determined the

Abstract:

Antimicrobial peptides are among the repertoire of host innate immune defenses. In mucosal immunity, the health-disease balance can be greatly modulated by the interplay between host immune factors and colonized microflora. Microbial ecology within dental plaque is constantly shaped by environmental factors present within the oral cavity. Several antimicrobial peptides are detected in saliva and their bactericidal activities against oral bacteria, including Streptococcus mutans, the primary etiologic agent of dental caries, have been clearly demonstrated. However, the role of these antimicrobi

Abstract:

The prevalence of obesity is continually rising in developed countries like the United States. Based on the association between periodontitis and obesity and the relationship between periodontitis and peri-implantitis, it is important to understand the implications of obesity on peri-implant health. A potential relationship between obesity and peri-implant health has practical, biological and financial implications. The primary objective of this study was to determine the association between obesity as measured by the body fat indices (body mass index (BMI), waist circumference (WC), and body

Abstract:

Background Anxiety experienced by individuals visiting the dental office to receive treatment is prevalent in the population. The clinical manifestation of these anxieties is considerable; it is estimated that approximately between 14 and 30 million people in the United States do not seek routine dental care due to dental anxiety. Dentists and other scientists have explored many techniques and procedures in attempts to ameliorate these anxieties and improve patient care. Biofeedback is a process that involves measuring a person's specific bodily functions such as blood pressure, heart rate, sk

Abstract:

Sphingoid bases (sphingosine, dihydrosphingosine and phytosphingosine) have been recently found in the oral cavity where they may serve to fortify innate immunity against commensals and periodontal pathogens. In fact, sphingoid bases have potent antimicrobial activity against Gram- positive and Gram- negative bacteria including oral pathogens like Porphyromonas gingivalis. It is not known whether these lipids are cytotoxic or alter the chemokine and cytokine responses of human dendritic cells, a finding important to their
