Negative Pressure Wound Therapy For Complex Oral Wounds, Mykaihla Sternick, James Gates, Allen Champion, Andrew Yampolsky

Department of Oral and Maxillofacial Surgery Faculty Papers

Negative pressure wound therapy provides a nonsurgical treatment option for many types of complex wounds. This therapy utilizes the vacuum-assisted closure device, which decreases air pressure, removes fluid that accumulates within the wound, and aids to facilitate changes that promote healing. Despite the increased use of negative pressure wound therapy in the head and neck region, there is substantially less data available on the management of transoral vacuum-assisted wound closure. Herein, we present a case of a novel approach for the creation and use of a transoral wound vac for a patient with a refractory orocutaneous wound in the setting …

Genetically Engineering Gingipains For High Yield Large Scale Purification., Andrew E. Fuchs

Electronic Theses and Dissertations

Porphyromonas gingivalis is a keystone oral pathogen in the progression of periodontal disease and has been implicated in the etiology of many other systemic human diseases. P. gingivalis produces primary virulence factors termed the gingipains, a group of cysteine proteases. There is a high demand for high purity gingipains for downstream in vitro studies where P.g. is implicated, both oral and systemic. Gingipain production candidate mutant P.g. strains were generated to isolate each gingipain for large scale purification and the purified gingipains characterized. Two mutants were determined not to be viable for large scale purification of gingipains, each for different …

Endodontic Therapy, Crown Amputation, And Soft Tissue Advancement To Treat A Hopeless Tooth, Timothy Daws Dds, Thomas Bolten Dds, Md

The Journal of the Michigan Dental Association

Managing patients with a history of intravenous bisphosphonates and antiresorptive medications poses challenges in clinical decision-making. Extractions are generally discouraged in these patients due to the risk of medication-related osteonecrosis of the jaw (MRONJ). This case study presents an 89-year-old female with metastatic breast cancer on Xgeva, facing a non-restorable tooth (#30). A collaborative approach involving the general dentist, endodontist, and oral surgeon employed endodontic therapy, crown amputation, and soft tissue advancement, avoiding extraction. The technique, akin to coronectomy, mitigates MRONJ risk by preserving bone integrity. Follow-up assessments indicate successful treatment without complications, highlighting the efficacy of this approach in …

Root And Canal Morphology Of Mandibular Second Molars In An Egyptian Subpopulation: A Cone-Beam Computed Tomography Study, Shehabeldin Mohamed Saber Prof.Dr.

Dentistry

Background: This study was using Cone beam computed tomography (CBCT) to examine the anatomical variations in mandibular second molars in an Egyptian sub-population. Methods: A total of 350 CBCT images (215 females and 135 males, aged 15–65 years) of mandibular second molars were evaluated. Samples were evaluated in terms of: number of roots, number of root canals, roots’ cross section as well as prevalence and configurations of C-shaped canals. Statistical analysis was done to highlight differences between different categories and their prevalence among genders (significance level was set at p < 0.05). Data were presented as frequency and percentage values and were analyzed using chi square test followed by pairwise comparisons utilizing multiple Fisher’s exact tests with Bonferroni correction. The significance level was set at p < 0.05 within all tests. Results: Of the 350 mandibular second molars evaluated, 87.2% were non-C-shaped while 12.8% were C-shaped with no gender-based statistically significant differences (χ2 = 0.19, p = 0.656). Most samples had three root canals (80%) followed by two (16%), then one (3.2%), and finally four (0.8%) root canals. Among the non-C-shaped molars, presence of two roots was most common (83.4%) followed by presence of a single root (16.2%), and only one sample (0.2%) had three roots, and this had no correlation with gender (χ2 = 1.86, p = 0.431). In the mesial roots Type IV Vertucci was the most common configuration found (68.8%), while Type I was the most prevalent in the distal roots (91.8%). The long oval configuration was the most commonly found cross section in mesial roots while “oval” was the most prevalent in distal roots. Conclusion: Egyptian sub-population shows highly variable morphological features in mandibular second molars, hence, CBCT is highly recommended on case-to-case conditions.

Effects Of Antiresorptive Medications On Tooth Root Formation And Tooth Eruption In Paediatric Patients, Yuki Arai, Jeryl D English, Noriaki Ono, Wanida Ono

Faculty, Staff and Student Publications

Tooth eruption is a pivotal milestone for children's growth and development. This process involves with the formation of the tooth root, the periodontal ligament (PDL) and the alveolar bone, as the tooth crown penetrates the bone and gingiva to enter the oral cavity. This review aims to outline current knowledge of the adverse dental effects of antiresorptive medications. Recently, paediatric indications for antiresorptive medications, such as bisphosphonates (BPs), have emerged, and these agents are increasingly used in children and adolescents to cure pathological bone resorption associated with bone diseases and cancers. Since tooth eruption is accompanied by osteoclastic bone resorption, …

Multi-Omics Analysis In Developmental Bone Biology, Yuki Matsushita, Azumi Noguchi, Wanida Ono, Noriaki Ono

Faculty, Staff and Student Publications

Single-cell omics and multi-omics have revolutionized our understanding of molecular and cellular biological processes at a single-cell level. In bone biology, the combination of single-cell RNA-sequencing analyses and in vivo lineage-tracing approaches has successfully identified multi-cellular diversity and dynamics of skeletal cells. This established a new concept that bone growth and regeneration are regulated by concerted actions of multiple types of skeletal stem cells, which reside in spatiotemporally distinct niches. One important subtype is endosteal stem cells that are particularly abundant in young bone marrow. The discovery of this new skeletal stem cell type has been facilitated by single-cell multi-omics, …
