Bridging The Gap In Dentistry: Harnessing Behavioral Health To Improve Oral Health Outcomes For Autistic Youth, Serenity Richardson

2026 Research Poster Competition

Background: Autistic children have unique dental healthcare needs. Oral complications stemming from poor tongue and motor coordination, high sensitivity to toothpaste and flossing, and sensory reactions to fluoride, amalgam, and other dental products are common. Autistic youth are also prone to dental-related emotional (e.g., dental fear and anxiety) and behavioral (e.g., noncompliance, disruptive behavior, avoidance) symptoms. There is also a substantial gap in pediatric and autism-focused training for dental providers, and caregivers report significant challenges in finding dental practitioners who treat autistic children. Taken together, autistic youth and their families face barriers to accessing timely, equitable oral healthcare. Unfortunately, delayed …

Embracing Imperfection And Stress As The Foundation For Growth, Excellence, And Well-Being In Dentistry, John W. Claytor Jr., Dds, Magd-Llsr, Facd

Influence Of Serum Vitamin D Levels On Marginal Bone Loss Around Unsplinted Mandibular Implant Overdentures: A Retrospective Study, Rahma El Hussany Mohammed El Desouky, Fatma Ahmad El-Waseef

Mansoura Journal of Dentistry

Objective: To investigate the impact of serum vitamin D levels on marginal bone loss (MBL) in patients restored with unsplinted-mandibular-implant overdentures using LOCATOR attachments. Materials and Methods: Thirty participants rehabilitated with three-implant-mandibular overdentures were included. Based on serum vitamin D at the time of prosthetic loading, participants were categorized into two equal groups: a test group with deficient vitamin D (< 20 ng/mL) and a control group with sufficient levels (≥30 ng/mL). Patients with borderline levels (21–29 ng/mL) were excluded. Peri-implant vertical (VBL) and horizontal bone loss (HBL) were measured at baseline (T0), 6 months (T6), and 12 months (T12). Results: The vitamin D-deficient group exhibited significantly elevated VBL and HBLover the sufficient group at all-time points (P

Cephalometric Norms And Sexual Dimorphism In The Tanzanian Population: A Comparative Study With Caucasian And West African Norms, Ali K. Hamad, Ferdinand M. Machibya, Matilda M. Mlangwa, David N. Ngassapa

Mansoura Journal of Dentistry

Objective: This study aimed to establish cephalometric norms for the Tanzanian population, assess sexual dimorphism in cephalometric measurements, and compare these findings with established Caucasian and West African norms to enhance orthodontic diagnosis and treatment planning. Materials and Methods: A crosssectional study was conducted on 309 subjects (142 males, 167 females) at Muhimbili University Dental Clinic. Cephalometric radiographs were digitally traced using Quick Ceph Studio. Reliability was assessed using the inter-class correlation coefficient. The Kolmogorov-Smirnov test checked normality, while one-sample t-tests and Student’s ttests (p < 0.05) were used for comparisons. Data were analyzed with RStudio. Results: Tanzanians showed significantly smaller craniofacial measurements than Caucasians. Males had larger skeletal dimensions than females. Compared to West Africans, Tanzanians had generally higher values, with a few exceptions. Conclusion: Tanzanians display distinct craniofacial characteristics, differing from both Caucasians and West Africans. These findings support the need for population-specific cephalometric norms to guide accurate orthodontic diagnosis and treatment.

Molar-Incisor Hypomineralization: Diagnosis, Management, And Treatment, Giovana Anovazzi Medeiros Dds, Msc, Phd, Bahareh Enghiad Dmd, James R. Boynton Dds, Ms

The Journal of the Michigan Dental Association

Molar Incisor Hypomineralization (MIH) is a qualitative developmental enamel defect affecting at least one permanent first molar. Characterized by high porosity and reduced mineral content, MIH leads to hypersensitivity, post-eruptive breakdown, and increased caries susceptibility. The etiology is multifactorial, typically occurring between birth and four years of age. Management depends on severity, ranging from topical fluorides and sealants for mild cases to stainless-steel crowns or extractions for severe instances. Because porous enamel facilitates bacterial penetration and pulpal inflammation, achieving effective local anesthesia is often difficult, necessitating individualized behavioral management and early intervention to preserve tooth structure.

What About Our Teen-Age Patients?, Michelle C. Dziurgot

The Journal of the Michigan Dental Association

This editorial advocates for "mentally treating" teenage patients, specifically those around 14 years of age, as adults. By respecting their concerns and allowing age-appropriate decisions, clinicians can enhance a teen's dental IQ and self-esteem. This approach fosters confidence, communication, and independence, encouraging patients to take accountability for their treatment outcomes. Respectful dialogue leads to better compliance with home care, such as using rotary brushes or wearing retainers. Ultimately, treating teenagers with empathy and valuing their opinions helps them blossom into responsible adults while building lasting professional bonds.

Pediatric Dentists’ Best Practices When Treating Children With Autism Spectrum Disorders: A National Survey, Samita Gumber Bds, Mds, James R. Boynton Dds, Ms, Larry B. Salzmann Dds, Rodney J. Vergotine Bchd, Msc(Dent), Faapd, Fiadt, Fabpd, Ficd, Marita R. Inglehart Dipl. Psych., Dr. Phil., Dr. Phil. Habil

The Journal of the Michigan Dental Association

This national survey evaluates how pediatric dentists manage patients with Autism Spectrum Disorder (ASD). While most practitioners collect data on oral hygiene and verbal communication, fewer assess social interaction or sensitivity-related characteristics. The study suggests using supplemental intake forms to plan appointments based on individual needs and functioning levels. Key accommodations reported include behavior guidance, modified appointment times, and operatory adjustments. Results indicate that increased professional experience with ASD correlates with more comprehensive data collection and a higher perceived value of that information. Ultimately, partnering with parents is vital for creating successful dental encounters for children with ASD.

Modulating Oran Nitrate-Reducing Bacteria To Enhance Nitric Oxide Bioavailability As A Therapeutic Target For Atherosclerosis, Donovan C. Davidson

CMC Senior Theses

Atherosclerosis remains the primary driver of global cardiovascular disease, yet clinical interventions are largely restricted to high-cost, invasive procedures only after it has reached a critical stage. Recent research has identified a connection between the oral microbiome and vascular health via the enterosalivary nitrate-nitrite-nitic oxide (NO) pathway. Oral nitrate-reducing bacteria (ONRB) drive the synthesization of NO by reducing dietary nitrate into nitrite, which is then converted into bioavailable NO. NO is a potent vasodilator that maintains endothelial health by suppressing inflammation through inhibiting the expression of adhesion molecules VCAM-1 and ICAM-1. However, this pathway is easily compromised by dysbiotic oral …
