Impact of Special Olympics Special Smiles Participation on Dental and Dental Hygiene Students’ Attitudes and Comfort Working with Individuals with Intellectual and Developmental Disabilities

The primary aim of this study is to evaluate the impact of participation in Special Olympics Special Smiles on dental and dental hygiene students’ attitudes toward individuals with IDD and their self-reported comfort levels in providing oral healthcare to this population. A secondary aim is to explore whether participation influences students’ perceived preparedness and interest in treating patients with IDD in their future professional practice. We hypothesize that students who participate in Special Olympics Special Smiles will demonstrate significant improvements in attitudes, comfort, and perceived readiness to work with individuals with IDD compared to their pre-participation measures.

The student researchers will assist with conducting the literature review and developing the background and rationale for the study, including drafting the introduction. Under faculty guidance, students will implement validated survey instruments by creating Qualtrics© surveys, coordinating and conducting data collection, and assisting with data management and organization. Students will also contribute to the interpretation of results by assisting with the discussion section and reflecting on the educational implications of the findings.

Because data collection can only occur during Special Olympics Special Smiles events, I anticipate that it may take another year or more to obtain a sufficient sample for a manuscript suitable for publication. Students who join the project would have opportunities to assist with data collection and Qualtrics survey administration at Special Smiles events, contribute to data management and analysis, and participate in manuscript preparation as the project progresses toward publication.

As a clinician-scientist, my research focuses on oral-systemic health interactions in older adults with complex medical histories. Specifically,  for patients with terminal illnesses, my work aims to understand their dental treatment needs and care preferences, which is essential to ensure the quality of care for this vulnerable patient population. I'm also working with OSU's palliative care and oncology teams to integrate oral health care into their practices, providing much-needed preventive care to those who otherwise have no access to regular dental care during their medical visits. For older adults with cognitive impairment, my work aims to understand how cognitive impairment affects oral self-care and other dental-related functions, and to develop functionally tailored oral health interventions to support patients and their caregivers.

Faculty Name: Brian Foster, PhD

My overarching objective as a researcher in the dental-oral-craniofacial field is to understand the molecular mechanisms driving tooth root formation and bring that insight to novel approaches for regenerating tissues and restoring function. To date, specific areas of inquiry have included phosphate/pyrophosphate metabolism and dentoalveolar development and regeneration, developmental regulators of cementum, functions of extracellular matrix proteins in dental development and mineralization, and manifestations of skeletal and endocrine diseases in the craniofacial and dental tissues. More broadly, I am also interested in how knowledge gained from the study of dental-oral-craniofacial connective tissues may also be applied to skeletal development, disease, wound healing, and regeneration.

Project 1. Using Photocatalytic Dental Materials to Control Dental Caries

Dental caries develops when the oral biofilm shifts from a healthy microbial community toward a more acid-producing and acid-tolerant community. In a healthy biofilm, some commensal bacteria help control Streptococcus mutans by naturally producing hydrogen peroxide (H2O2). However, under cariogenic conditions such as frequent high-sugar exposure, bacterial H₂O₂ production can be reduced, weakening this natural protective effect. Our project studies photocatalytic metal titanates as a way to provide an external source of H2O2 and other reactive oxygen species (ROS) to help suppress S. mutans and support a healthier biofilm environment.

Project 2. Using AI to Efficiently and Precisely Discover New Anti-Caries Probiotics

Dental caries, the most prevalent health condition worldwide, results from an ecological shift toward acidogenic, acid-tolerant microbial communities. Protective oral commensals offer an alternative to broad-spectrum antimicrobials, yet probiotic discovery remains slow, empirical, and biased toward readily cultivable, well-studied organisms. Genome sequencing expands the search space, but gene presence alone does not establish function. A major gap in probiotic development is the lack of an integrated framework to evaluate mechanism, target specificity, resilience under cariogenic stress, restoration of oral biofilm homeostasis, and host safety together.

We are developing an AI platform that models the complexity of the oral environment and connects genomic information, laboratory experiments, microbial interactions, environmental conditions, and safety. The goal is to move more efficiently from genes → predicted function → laboratory validation → clinically useful probiotic candidates, reducing trial-and-error and accelerating the development of anti-caries probiotics.

Faculty Name: Justin Kaspar, PhD

Microbes exist within complex communities, often referred to as a microbiome. The human oral microbiome contains upwards of 700 different species, living within different niches of the oral cavity. One of those niches are supragingival biofilms, or microbial biofilms attached to the exposed surfaces of teeth. While several species that live in these communities can promote the host’s oral health, others, such as Streptococcus mutans, convert dietary carbohydrates into acid that erodes the tooth’s enamel causing the formation of carious lesions. The goal of our research project(s) are to eliminate disease-associated bacteria like Streptococcus mutans through microbial ecological engineering — utilizing antagonistic exchanges between microbes to our advantage to specifically target a pathogen of interest, leaving intact health-associated bacteria to promote microbiome homeostasis and the maintenance of the host’s health.

My research has concentrated on two key areas within integrative oral bioengineering: the biomaterials and biomechanics involved in craniofacial bone remodeling and regeneration, and the application of advanced technology in clinical settings. A significant aspect of my work spans from foundational studies in material synthesis and alveolar bone remodeling- aimed at enhancing our understanding of the underlying biophysical principles—to clinically relevant investigations. These include the use of 3D imaging and artificial intelligence (AI), the study of implant osseointegration, osteoclastogenesis related to bone homeostasis, and the processes of tooth movement.

Faculty Name: Kyulim Lee, DMD, MS, PhD 

My research program investigates how oral microbial communities influence oral and systemic health across pediatric populations. Integrating clinical, translational and microbiome-based approaches, our work seeks to understand how shifts in the oral ecosystem contribute to disease development, treatment complications and recovery. Current studies focus on medically vulnerable children, particularly those undergoing hematopoietic cell transplantation, to investigate how changes in oral health and the oral microbiome influence oral mucositis, bloodstream infections and graft-versus-host disease. In parallel, I also study the microbial and environmental factors that contribute to dental caries, including diet-associated microbial changes and the role of oral bacteriophages in shaping microbial community structure and disease susceptibility. 

Faculty Name: Diana Leyva del Rio, DDS, MS, PhD

My research is focused on evaluating the mechanical performance of dental biomaterials, with particular emphasis on resin-based composites, denture and impression materials, liners, and 3D-printed polymers. My work explores how the material composition, polymerization protocols, fabrication methods, aging, and surface characteristics influence key physical, mechanical, and optical properties, including depth of cure, microhardness, flexural strength, fatigue and fracture resistance, adhesion, wettability, surface roughness, and color matching. Through in vitro experimentation, my research aims to better understand material behavior under clinically relevant conditions and identify factors that may improve the longevity, reliability, and overall clinical performance of contemporary restorative and prosthodontic materials. 

Faculty Name: Miaomiao Li, PhD

Dr. Li's research mainly focuses on understanding the role of heparan sulfate in bone health and inflammation, with the goal to develop novel therapy towards osteoporosis, rheumatoid arthritis and periodontitis. Heparan sulfate is an essential polysaccharide universally expressed at the cell surface and in the extracellular matrix. By interacting with hundreds of proteins, heparan sulfate plays significant roles in human health and disease, which makes it represent a class of biomolecule of great pharmaceutical interests. Dr. Li has extensive experience studying how heparan sulfate works with specific proteins like osteoprotegerin, RAGE, and sclerostin, which are important for bone health and inflammation. The long-term goal of the Li lab is to use this knowledge to develop new treatments that can target heparan sulfate–protein interactions and help treat bone and inflammatory diseases.

Why do patients with X-linked hypophosphatemia (XLH) develop frequent dental abscesses, pulp infections, and periodontal disease, even when receiving current therapies? XLH is a genetic disorder caused by mutations in the PHEX gene that disrupt phosphate and vitamin D metabolism, leading to chronically low phosphate levels, impaired vitamin D regulation, and defective mineralization of bones and teeth. While these mineralization defects have traditionally been considered the primary cause of oral complications, our lab is investigating a novel hypothesis that altered immune responses also contribute significantly to dental and periodontal disease in XLH. Using the Hyp mouse model (an animal model that replicates this disease), we are examining how PHEX mutations affect immune cells, inflammatory pathways, and interactions with the oral microbiome that may increase susceptibility to pulp and periodontal infections. This highly interdisciplinary project combines dentistry, immunology, genetics, microbiology, and translational research, offering students opportunities to gain hands-on experience with animal models, histology, molecular biology, flow cytometry, microbiome analysis, and scientific communication. Beyond improving our understanding of XLH, the knowledge gained from this work may have broad implications for the general population, as inflammation, immune dysregulation, and host-microbe interactions are central drivers of common dental diseases such as endodontic infections and periodontitis. By uncovering fundamental mechanisms linking different disciplines, this research has the potential to identify new therapeutic targets that directly benefit rare disease patients. Indirectly, we believe that we can add knowledge to the field and bring benefits to the general population affected by oral inflammatory diseases. Dental students interested in understanding the biological basis of oral disease are encouraged to join our team.

Faculty Name: Sarah B. Peters, MS, PhD

I study the dentin-pulp complex through all stages of life including how teeth develop, how the dental pulp tissue responds to injury and/or inflammation,  how tooth healing can be enhanced to prevent secondary caries, and how teeth age on a molecular level. The dental pulp contains the most versatile stem cells of the body and the most sensory innervation of the body, and yet we our tooth restorations most often lead to extractions several years down the road. With our lifespans expanding, we need to develop treatment plans that last longer if we want to help our patients keep their teeth. We believe that our cellular and molecular studies of the dentin-pulp complex will pave the way to personalized treatments for each patient that will help us keep our natural teeth by creating cellular and material treatment plans that promote tooth vitality at all stages of life.

Faculty Name: Peter Reiser, MS, PhD

Potential Projects: CRANIOFACIAL MUSCLE SPECIALIZATIONS. The lab has a focus on the analysis of craniofacial muscles, at the molecular and cellular levels. Jaw-closing, extraocular and laryngeal muscles constitute a group of muscles that have highly specialized motor function. These muscles are recognized to also have complex patterns of sarcomeric protein isoform expression, which are much more elaborate that the patterns that exist in limb muscles. The challenge is to understand how specific sarcomeric proteins, and their individual isoforms, drive the broad repertoire of motor functions that are executed daily by craniofacial muscles. The approach is to study individual isolated muscle fibers by analyzing their contractile properties and the protein composition of the same fibers. The results are used to understand how sarcomeric proteins drive specific contractile properties and motor functions in vertebrate craniofacial muscles.

Student Skills: Students working in the laboratory must have the ability to isolate individual muscle fibers, by fine dissection, and be able to conduct analyses of single fiber protein composition. Extensive training is provided to promote the student's ability to successfully contribute to ongoing projects.

Student Restrictions: There are currently no restrictions in this laboratory on students for participation in the SRP.

Faculty Name: Hillary Schiff, PhD

Potential Projects: My research program focuses on postnatal development of the neural circuits that underlie taste-based behaviors such as sensation, perception, reward, and feeding. We examine maturation of inhibitory neurons and synaptic transmission, plasticity, and microcircuitry in the cortical sensory region for taste, the gustatory cortex. In addition, we study the mechanisms by which taste and nutrient-sensing modulate one another and how these processes shape taste preferences, especially for sugars. Because our taste preferences play an outsized role in determining diet, these research questions have profound implications for nutritional status and diseases around eating including eating disorders, obesity, and type 2 diabetes. In the lab, we use patch clamp electrophysiology, animal behavior, neural tracing, and fiber photometry imaging to probe these questions.

Student Skills: Preferred skills include experience handling mice, pipetting, basic data analysis.
