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, …

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 …

Strategies To Encourage Recall And Prevent Relapse After Full Mouth Rehabilitation Under General Anesthesia In Children, Claire Koukol

Capstone Experience: Master of Public Health

Background: Dental caries are preventable. Dentists utilize many prevention strategies in the office and provide at-home education to families. However, once a child develops Early Childhood Caries (ECC), especially in more severe cases, they may need general anesthesia (GA) to complete treatment. While this is an effective way to achieve full mouth dental rehabilitation (FMDR), this burdens the healthcare systems and families and does not come without risk to the patient. Patients with high caries experience remain at high risk of caries relapse after FMDR under GA, sometimes necessitating additional FMDR under GA. While there has been a significant amount …

Nutrition Needs Assessment For A Produce Prescription Program In The Pediatric Dental Setting, Zachary Houser

Capstone Experience: Master of Public Health

More than half of young people in the U.S. aged 2-19 have a poor-quality diet, including low fruit and vegetable (FV) intake (Liu et al., 2020). Poor nutrition increases health risks, including chronic diseases such as dental caries and obesity, low-income households experience higher rates of poor nutrition and subsequent health burdens (AAPD, 2022b). Produce prescriptions (PPR) are a type of financial incentive program that can improve FV intake among low-income populations (Ridberg et al., 2019). PPR programs are often conducted in a primary medical setting (Little et al., 2022); however, no literature describes PPR programs conducted in a dental …

Occlusive Membranes For Guided Regeneration Of Inflamed Tissue Defects., Woojin Choi, Utkarsh Mangal, Jin-Young Park, Ji-Yeong Kim, Taesuk Jun, Ju Won Jung, Moonhyun Choi, Sungwon Jung, Milae Lee, Ji-Yeong Na, Du Yeol Ryu, Jin Man Kim, Jae-Sung Kwon, Won-Gun Koh, Sangmin Lee, Patrick T J Hwang, Kee-Joon Lee, Ui-Won Jung, Jae-Kook Cha, Sung-Hwan Choi, Jinkee Hong

Henry M. Rowan College of Engineering Departmental Research

Guided bone regeneration aided by the application of occlusive membranes is a promising therapy for diverse inflammatory periodontal diseases. Symbiosis, homeostasis between the host microbiome and cells, occurs in the oral environment under normal, but not pathologic, conditions. Here, we develop a symbiotically integrating occlusive membrane by mimicking the tooth enamel growth or multiple nucleation biomineralization processes. We perform human saliva and in vivo canine experiments to confirm that the symbiotically integrating occlusive membrane induces a symbiotic healing environment. Moreover, we show that the membrane exhibits tractability and enzymatic stability, maintaining the healing space during the entire guided bone regeneration …

Vaping Is More Dangerous Than You Think, Chantel Perreault, Jodi Poirier, Chantelle Vazquez, Kaelyn Gallipeau

Dental Hygiene Student Research Posters

It is predicted that cigarette smokers and users of electronic nicotine delivery systems (ENDS) have poor periodontal health and greater levels of the inflammatory cytokines IL-15 and IL-18 in their saliva, compared to nonusers. Electronic cigarettes heat the liquid within the cartridge at a level that permits the individual to inhale. The inhalation within the lungs leads to tooth decay, gum disease and even oral cancer. The studies included in this review revealed that e-cigarette users had a higher risk of periodontal disease, tooth loss, and bone loss. This is due to vapor leaving a residue behind on teeth, known …

Periodontal Disease And Alzheimer’S Disease, Lexis Labonte, Jaycee Cole

Dental Hygiene Student Research Posters

There is a direct correlation between patients with periodontal disease and negative cognitive decline or Alzheimer’s disease. Research has proven that those who suffer from Alzheimer’s/dementia have a reduced dentition which negatively impacts masticatory function. With impaired masticatory function, it leads to poor nutrition which has a direct effect on cerebral stimulation and blood flow which worsens the effects of Alzheimer’s. The bacteria that is present during periodontitis, causes a spike in inflammatory cytokines. These cytokines invade the brain and trigger CNS inflammation which leads to cognitive decline.

Dentistry And The Law: Problems With Referral Incentives Explained, Dan Schulte Jd

The Journal of the Michigan Dental Association

Incorporating referral incentives in dentistry, like gift cards or raffles, can present ethical and legal issues. The MDA's ethical rule 4.E prohibits rebates or fee splitting, extending to any referral source, including patients. Gift cards may be perceived as rebates. Raffle tickets are less problematic, but only the winner gains something of value. State law (MCL 333.16221) deems fee division unethical. For insurance and dental plan agreements, check for clauses mandating specific fee schedules and discouraging referral fees to ensure compliance. Federal laws might also apply if incentives are used for Medicaid or Medicare patients.
