Effect Of Expansive Force On Mesenchymal Stem Cells Isolated From The Mid-Palatal Suture Of Mice, Samaneh Mojarrad 2018 University of Pennsylvania

Effect Of Expansive Force On Mesenchymal Stem Cells Isolated From The Mid-Palatal Suture Of Mice, Samaneh Mojarrad

Dental Theses

Understanding the mechanisms by which craniofacial sutures respond to mechanical force is essential for improving orthodontic treatment strategies. However, the innate ability to regenerate bone from calvarial stem cells is still unknown. Therefore, we have initiated a study to isolate cells from the mid-palatal suture of mice. The aim of our study is to evaluate mesenchymal stem cell (MSC) characteristics of cells isolated from the mid-palatal suture and their ability for osteogenic differentiation when subjected to cyclic tensile force in vitro. A total of 10, 6-week old male C57BL/6 mice were used to obtain mid-palatal suture cells. Cultured cells ...

Using The Rat Grimace Scale To Detect Orofacial Pain In Mechanically-Induced Temporomandibular Joint Pain In Rats, Ya-Hsin Yu, Megan M. Sperry, Beth A. Winkelstein, Eric J. Granquist

Dental Theses

Introduction: Orofacial pain in animal models of TMJ disorders is typically evaluated by measuring evoked reflexive responses. Since the rat grimace scale (RGS) was adopted recently to assess spontaneous pain in other pathologies, this study evaluated its effectiveness for TMJ pain in the rat. RGS was evaluated using a well-defined pain model of TMJ loading.

Material and Methods: Female Holtzman rats were assigned to separate groups: loading (n=10); sham (n=4); loading with naproxen (n=4) or vehicle (n=3) on days 4 and 5 after pain developed. Jaw loading was imposed for 7 consecutive days under anesthesia by ...

Department of Oral and Maxillofacial Surgery Posters

Obstructive sleep apnea (OSA) is a well-recognized disease entity affecting approximately 2% to 4% of the population. Maxillomandibular advancement (MMA) surgery is a highly successful surgical alternative to poorly tolerated CPAP therapy and achieves a success rate of 89% in the current literature. Our present study evaluates the effectiveness of MMA surgery in the treatment of patients with moderate to severe OSA based on Shers criteria of 50% reduction in AHI and AHI < 20. Radiographic and clinical treatment variables were evaluated in determining predictors of success for MMA in individuals with OSA.

Variation In And Assessment Of Inferior Alveolar Nerve Block Landmarks In Children And Adolescents, Soi Park, Younjin Lee, Younyoung Lee, Tiffany Tran, Gary D. Richards

Excellence Day

OBJECTIVES: In earlier work (Lambert et al., 2017) we demonstrated the efficacy of new landmarks for inferior alveolar nerve (IAN) block injections. While the latter study focused on adult morphology, the landmarks were shown to be effective in cases where the M3/3 were present but unerupted. Based on these result a question arose as to their applicability of the landmarks to children and adolescents, given the known changes in mandibular foramen position during growth. Here we quantify the position of the mandibular foramen relative to standard landmarks during growth and assess the new landmarks applicability for IAN injections ...

Posterior composites have long had a reputation for being difficult and time consuming in clinical practice. In addition to this reputation, it has been noted that recurrent caries and in general failure of these restorations prematurely has been a problem. Relative to amalgams, posterior composites have vexed even good clinical dentist. This video presentation illustrates techniques that not only save time but also create more predictable high-quality restorations.


Genes Associated With Mandibular Prognathism In The Chinese Population, Jacqueline Payne, Marie Tolarova M.D., Ph.D., D.Sc. 2018 University of the Pacific Dugoni Dental School

Genes Associated With Mandibular Prognathism In The Chinese Population, Jacqueline Payne, Marie Tolarova M.D., Ph.D., D.Sc.

Excellence Day

Mandibular prognathism (MP) is the relationship of the mandible anteriorly positioned in relation to the cranial base. The prevalence of MP in Asians is estimated to be 15%, whereas American and European descent exhibit a 5% prevalence. Orthodontic treatment is lengthy and challenging, and severe cases require surgical intervention. However, when a treatment is planned well, the outcomes are predominantly successful. It has been known that genetics are involved in the etiology of prognathism and that greater genetic contribution corresponds to greater challenges to treatment. Thus, there is a desire to determine genes involved in the etiology of prognathism.

The Role Of Aryl Hydrocarbon Receptor (Ahr) Signaling Pathway In Oral Squamous Cell Carcinoma (Oscc): Preliminary Results., Renee Lee, Cui Xu, Leticia Ferreira, Ana Carolina Morandini, Erivan Ramos-Junior

Excellence Day

OBJECTIVES: A large number of experimental and clinical studies suggest that the origin of oral squamous cell carcinoma (OSCC) is linked to environmental carcinogenesis (tobacco, alcohol). Among these environmental factors, cigarette smoking is the most studied and has been associated with increased susceptibility to OSCC by activating signaling pathways responsible for cancer initiation and progression. Besides nicotine, cigarette smoke also contains aryl hydrocarbon receptor (AhR) agonists, such as dioxin and benzo(a)pyrene. Aberrant AhR expression and AhR pathway activation are involved in several types of cancer. However, the relationship between AhR pathway activation and oral cancer progression is still ...

Root Analogue Implant Creation: Establishing Procedures For The General Dentist, Alicia Hazdovac, Sarah Osborne, Gary D. Richards

Excellence Day

The possibility of replacing damaged teeth with custom-made root analogue implants was initially suggested around 1969 and reintroduced by Lungren et al. in 1992. The latter authors created custom implants in titanium and reported good osteointegration and aesthetic results. Following this effort there has been an increasing focus on custom root analogue implants as a replacement for ‘screw-type’ implants. Given the availability of software to manipulate 3D image data and the rapid rise of 3D printing technology, the question arises as to whether a general dentist can produce their own implants. Here we test the feasibility of practitioners producing custom ...
