Dental Public Health and Policy Publications
Non-Hispanic Black (NHB) and Hispanic and low-income US children have a higher prevalence of untreated caries than their higher-income and non-Hispanic White (NHW) counterparts. Due to the COVID-19 pandemic, many dental offices and school sealant programs closed beginning March 2020. We examine the effect of reduced access to restorative care and sealants on the oral health of children from low-income households overall and by race/ethnicity and how increased sealant delivery in September 2022 could mitigate these effects. We used Markov chain Monte Carlo simulation to model COVID-19’s impact on first permanent molar (1M) caries incidence and loss in quality of …

Peri-Implantitis Incidence And Effect Of Supportive Periodontal Therapy On Outcomes: Retrospective Cohort Study, Michael Ha
Theses and Dissertations
Purpose: Management of peri-implantitis is becoming an increasing component of dental practice. Dental implants can develop peri-implantitis lesions which occur in a non‐linear and accelerating pattern compared to a gradual periodontitis lesion. It is crucial to diagnose and treat this disease early, or ideally prevent it. Contemporary implants have a rough surface texture which is difficult to properly decontaminate as a crucial component for treatment prognosis. Evidence on the long-term effects of Periodontal implant maintenance therapy (PIMT) on implants is limited. This study aims to investigate the effect of periodontal maintenance on peri-implant tissue health.

Aims: Platelet rich plasma (PRP) has been used in tissue repair to treat numerous inflammatory pathophysiologies. Recent studies have elucidated that the bioactive lipid fraction of PRP significantly contributes towards the resolution of inflammation. There has been great interest in how therapeutics could modulate the PRP lipidome to formulate a more pro-resolving matrix. Many of the pathways used to produce either pro-resolving or pro-inflammatory lipids are shared between ω-3 and ω-6 polyunsaturated fatty acids (PUFA). Here, we explored the separate and interacting effects acute exogenous ω-3 PUFA supplementation and aspirin had on the lipidome of PRP within 6 hours.
