School of Dentistry Faculty Research and Publications

Periodontal diseases, a group of complex conditions marked by an excessive immune response and periodontal tissue destruction, are a global health concern. Since 1990, the incidence of these diseases has doubled, with Western sub-Saharan Africa experiencing the highest burden. Accurate diagnosis and case identification are crucial for understanding the etiology, features of disease, research, treatment and prevention. Modern perspectives on periodontal disease classification are based on commonality among those affected. However, current literature is often plagued by methodological inconsistencies and focused on disease mechanisms in European populations. Health inequalities in low- and middle-income countries (LMICs) are exacerbated by these challenges, …

Runx2 Is Essential For Maintaining Synchondrosis Chondrocytes And Cranial Base Growth, Shawn A Hallett, Ashley Dixon, Isabella Marrale, Lena Batoon, José Brenes, Annabelle Zhou, Ariel Arbiv, Vesa Kaartinen, Benjamin Allen, Wanida Ono, Renny T Franceschi, Noriaki Ono

Faculty, Staff and Student Publications

The cranial base synchondroses, comprised of opposite-facing bidirectional chondrocyte layers, drive anteroposterior cranial base growth. In humans, RUNX2 haploinsufficiency causes cleidocranial dysplasia associated with deficient midfacial growth. However, how RUNX2 regulates chondrocytes in the cranial base synchondroses remains unknown. To address this, we inactivated Runx2 in postnatal synchondrosis chondrocytes using a tamoxifen-inducible Fgfr3-creER (Fgfr3-Runx2cKO) mouse model. Fgfr3-Runx2cKO mice displayed skeletal dwarfism and reduced anteroposterior cranial base growth associated with premature synchondrosis ossification due to impaired chondrocyte proliferation, accelerated hypertrophy, apoptosis, and osteoclast-mediated cartilage resorption. Lineage tracing reveals that Runx2-deficient Fgfr3+ cells failed to differentiate into osteoblasts. Notably, Runx2-deficient chondrocytes showed …

Control Of Alveolar Bone Development, Homeostasis, And Socket Healing By Salt-Inducible Kinases, Nicha Tokavanich, Byron Chan, Katelyn Strauss, Christian D Castro Andrade, Yuki Arai, Mizuki Nagata, Marc Foretz, Daniel J Brooks, Noriaki Ono, Wanida Ono, Marc N Wein

Faculty, Staff and Student Publications

Alveolar bone supports and anchors teeth. The parathyroid hormone-related protein (PTHrP) pathway plays a key role in alveolar bone biology. Salt-inducible kinases (SIKs) are important downstream regulators of PTH/PTHrP signaling in the appendicular skeleton, where SIK inhibition increases bone formation and trabecular bone mass. However, the function of these kinases in alveolar bone remains unknown. Here, we report a critical role for SIK2/SIK3 in alveolar bone development, homeostasis, and socket healing after tooth extraction. Inducible SIK2/SIK3 (Ubq-creERt;Sik2f/f;Sik3f/f) deletion led to dramatic alveolar bone defects without changes in tooth eruption. Ablating these kinases impairs alveolar bone formation due to disrupted osteoblast …

Comparison Of Hand-Wrist And Cvms Methods For Craniofacial Growth Spurt Assessment, Ardita Ajvazi

Master's Theses (2009 -)

Objective: Hand-wrist (HW) radiographs are considered the most accurate method for assessing pubertal growth spurts in orthodontics but have declined in use due to added radiation exposure and the expertise required. Cervical vertebral maturation staging (CVMS) is now commonly used, given the routine availability of lateral cephalograms. However, the validity of CVMS remains uncertain. A recent study reported only 66% inter-observer reliability across time periods (Ingersoll, 2024). This follow-up study aims to evaluate CVMS as a predictor of growth to guide clinical decision-making. Methods: With protocol approval (MU HR-4695), this retrospective study followed a design modeled after a prior study …

Cone Beam Ct Assessment Of The Zygomatico-Maxillary Buttress For Bone Thickness And Clinical Implications For Miniscrew Insertion, Zachary Hendrickson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Temporary anchorage devices (TADs) have changed the way many orthodontists practice orthodontics. TADs are mini-screw temporary implants made of titanium or stainless steel that are placed in the patient's bone in different locations to aid in complex biomechanical movements. This complete anchorage aids in distalization, intrusion, protraction, etc. with less reliance on patience compliance. While TADs have made many movements easier, there are limitations such as choice of where to place it, skill at placing them and patient individual physiology and anatomy that can limit the use of TADs.Objectives: Infrazygomatic crest (IZC) TADs are particularly useful for distalization and …

Torque Efficacy Of Cadmus Bracket Design Using Clear Aligners, Joseph Soderberg

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Clear aligner therapy (CAT) is an alternative option for clinicians to use for orthodontic treatment as opposed to fixed appliances. Many patients prefer clear aligner therapy due to its esthetic looks, removability, ease of oral hygiene, and comfort. Clear aligner companies boast to clinicians that it can be used more efficiently and effectively than fixed appliances in many orthodontic cases. Although these claims have been made, there is a lack of evidence to prove that clear aligner therapy is more efficient or effective. This research will focus on torque control. This project is designed around a new, pre-manufactured attachment …
