Comparative Evaluation Of Bone Thickness In Infrazygomatic Crest Region For Optimal Insertion Of Bone Screws : A Cbct Study, Kavya Mp

Annual Research Symposium

Infrazygomatic crest (IZC) is a palpable bony ridge running between the alveolar ridge and the zygomatic process of maxilla. IZC bone dimension is an important factor in the safety and stability of bone screws. IZC thickness depends on the site of insertion, angulation and height from the occlusal plane. This study embarks on a comprehensive Cone Beam Computed Tomography (CBCT) exploration, to assess infra zygomatic Crest bone thickness.

Geranylgeraniol (Ggoh), Incorporated Into A Bone Cement Pellet Promotes Osteoclast Function And Healing In A Model Of Medication-Related Osteonecrosis Of The Jaw, George J Feldman, David Young, Theresa Freeman, Lauren Israel, Daniel Taub, Robert Diecidue

Department of Oral and Maxillofacial Surgery Faculty Papers

INTRODUCTION: There is no cause -based treatment for Medication-Related Osteonecrosis of the Jaw (MRONJ). MRONJ is a morbid condition including exposed, infected bone and mandibular fractures in osteoporotic individuals and metastatic cancers patients treated with nitrogen containing bisphosphonates (NBP). NBPs inhibit farnesyl diphosphate synthase (FDPS) in the mevalonate pathway, depriving osteoclasts and other bone cells of small GTPases necessary for their function and survival. We test the hypothesis that geranylgeraniol (GGOH),a metabolite downstream of FDPS, when incorporated into a bone cement pellet, enhances osteoclast function and promotes local bone healing in

METHODS:

RESULTS: The release of GGOH from bone cement …

Analysis Of The Soft Tissue Chin Profile In Acceptable Aesthetic Profiles Using A 3-Dimensional Camera Facial Scan System Compared To Normative Values Based On 2-Dimensional Radiographic Analysis, Sasawat Putpinij

Chulalongkorn University Theses and Dissertations (Chula ETD)

Chin profile plays a critical role in determining lower facial aesthetics, significantly affects perceptions of facial balance and attractiveness. Conventional assessment methods, which primarily rely on two-dimensional cephalometric norms, are limited by projection errors and a reduced capacity to accurately evaluate soft tissue contours. The development of three-dimensional facial scanning technology has facilitated more accurate assessment of facial morphology; nevertheless, aesthetic evaluation in acceptable aesthetic profile using 3-dimensional camera facial scan remains no evidence. Hence, this study aimed to investigate soft tissue chin profiles in clinically acceptable facial aesthetics using a three-dimensional camera system, comparing with traditional two-dimensional cephalometric values. …

The Effect Of Multimedia Information About Computer-Assisted And Freehand Dental Implant Surgery On Patients’ Knowledge, Anxiety, And Decision-Making, Veerawit Lukkanasomboon

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study aimed to evaluate the impact of multimedia and verbal information on patients' knowledge, anxiety, and decision-making regarding dental implant surgery, focusing on comparing computer-assisted and freehand techniques. This randomized controlled trial involved 100 patients divided into two groups: one receiving multimedia information (n=50) and the other receiving verbal information (n=50). Data were collected through self-administered questionnaires assessing patients' baseline information, knowledge, anxiety, and decision-making before and after receiving information about dental implant surgery techniques. Results showed significant increases in knowledge scores for both groups, with the multimedia group improving from 1.96 to 3.90 (p<0.001) and the verbal group from 2.0 to 3.98 (p<0.001). Anxiety levels decreased significantly in both groups, with reductions from 12.76 to 11.48 (p=0.001) in the multimedia group and from 13.92 to 12.16 (p<0.001) in the verbal group. The proportion of patients who decided to proceed with dental implant surgery increased from 70% to 78% in the multimedia group and from 54% to 66% in the verbal group. After receiving the information, more patients in both groups opted for computer-assisted implant surgery, though treatment costs remained a significant concern for some, leading to declines in surgery acceptance. Despite these findings, no significant differences were observed between the multimedia and verbal groups regarding knowledge improvements, anxiety reduction, or decision-making. In conclusion, multimedia and verbal information effectively enhanced patient knowledge and reduced anxiety about dental implant surgery, and both methods may influence patients' decisions regarding their preferred implant technique, with no significant differences between the two methods.

Anatomical Analysis Of Inferior Alveolar Nerve Relation To Mandibular Posterior Teeth Using Cone Beam Computed Tomography: A Retrospective Radiographic Analysis Study, Shehabeldin Mohamed Saber Prof.Dr.

Dentistry

Introduction: Cone beam computed tomography (CBCT) is reliable in the assessment of structures related to teeth. The assessment of the inferior alveolar neurovascular (IAN) bundle location using CBCT is considered one of its prime uses in different mandibular surgeries. Methodology: Retrospective CBCT data of patients presented to the institute were assessed to measure relations of IAN. Measurements were taken to assess the bone thickness adjacent to IAN, the superior-inferior dimension between the canal and the teeth, and the dimension between the canal and the inferior border of the mandible. Results: Out of the 170 patients the root apices nearest to …

Pdgfra And B Copositive Fibroblasts Drive Fibrosis In Mouse Salivary Glands Through Tgfβ Signaling, Renae Williams Atkinson

Electronic Theses & Dissertations (2024 - present)

Fibrosis is of significant concern to the medical community as numerous disease processes are characterized by progressive fibrosis leading to organ damage. We begin the process of examining the mechanism of fibrosis to salivary gland hypofunction and briefly consider Sjögren’s Disease (SjD). Method: We employed single-cell RNA sequencing data from a reversible mouse salivary gland injury model and from NOD/ShiLtJ mice, a model of secondary SjD. We performed treatment comparisons with the help of Seurat dotplots and UMAPS. Using differential gene expression analysis and the publicly available R packages: clusterProfiler, WikiPathways and Cytoscape, we identified the processes and pathways …
