Effects Of Non-Surgical Periodontal Therapy On Dental Plaque Microbiome, Qingguo Wang, Bing-Yan Wang, Derek Wilus, Hua Xie

Faculty, Staff and Student Publications

Periodontitis, a chronic inflammatory disease affecting approximately 40% of U.S. adults aged 30 years and older, is characterized by dysbiosis of the dental plaque microbiome. However, although scaling and root planing (SRP) is the cornerstone of periodontal treatment, its effects on the taxonomic composition and functional potential of the dental plaque microbiome remain incompletely understood. In this study, we used whole-metagenome shotgun sequencing to characterize taxonomic composition and functional potential in dental plaque microbiomes collected from 39 patients with Stage II or III generalized periodontitis before and 3–4 months after SRP. Consistent with clinical improvement, periodontal therapy significantly reduced probing …

Management Of Skeletal Class Iii Malocclusion With Deep Bite And Moderate Overjet Using Improved Super-Elastic Ti-Ni Alloy Wire (Isw), Wen-Hsuan Lin, Ching-Yu Yang, Yuan-Hou Chen, Jian-Hong Yu

Taiwanese Journal of Orthodontics

A 20-year-old female presented with concerns about poor dental alignment and a tendency to bite on her lip easily. Clinical examination revealed a concave and brachy facial profile, accompanied by a deep overbite and a moderate overjet. Radiographic examination showed skeletal Class III with a low mandibular plane angle. Correction of the deep bite was achieved by using the Improved Super-elastic Ti-Ni alloy Wire (ISW) and Intermaxillary elastics (IMEs). To correct the moderate overjet, interproximal reduction (IPR), the Multi-bend Edgewise Archwire (MEAW) technique, and arch lengthening of the lower arch were applied. The active treatment duration took approximately 54 months, …

Palatal Expansion Using The Invisalign Palatal Expander, Hassan Chihab

ETDs from 2020-2029

Palatal expansion has been used in orthodontics to treat a narrow maxilla and to primarily correct posterior dental crossbites. In younger patients, palatal expansion can readily be achieved through opening of the mid-palatal suture, as it is not fused at that age. As the mid-palatal suture matures, expansion will gradually be difficult to achieve, and more dental expansion is obtained rather than skeletal. In addition, there is a tendency to get more dental tipping. Palatal expansion has been recommended not only to correct crossbites but also to improve breathing in patients with sleep disorders such as obstructive sleep apnea (OSA). …

Deep Learning Single-Cell Analysis For Cytologic Evaluation Of Oral Potentially Malignant Disorders, Michael P Mcrae, Kritika S Rajsri, Nadarajah Vigneswaran, A Ross Kerr, Spencer W Redding, Martin H Thornhill, Craig Murdoch, Paul M Speight, Nancy Ruel, Rachelle Wolk, Ryan R Ruff, John T Mcdevitt

Faculty, Staff and Student Publications

Oral potentially malignant disorders (OPMDs) such as leukoplakia and erythroplakia may harbor dysplasia or progress to oral squamous cell carcinoma (OSCC), yet visual inspection alone is unreliable for risk assessment. Cytology offers a minimally invasive adjunct, but conventional approaches depend on manual feature extraction and subjective review. Herein we report a deep learning (DL) object detection model that directly classifies four cell phenotypes: differentiated squamous epithelial (DSE) cells, small round (SR) cells, leukocytes, and lone nuclei. The DL model produced cytology-derived parameters that correlated strongly with histopathologic diagnoses across 692 subjects with OPMDs, OSCC, and healthy controls, including declining DSE …
