Anticaries and Antigingivitis Properties of Cannabinoid-Containing Oral Health Products: A Review

To evaluate the anticaries and antigingivitis properties of cannabinoid-containing oral health products. A systematic research strategy was employed. Specific search terms were used, including "Cannabinoids AND dental caries," "Cannabinoids AND oral health," "Cannabinoids AND dental plaque," "Cannabinoids AND gingivitis AND periodontitis," "Cannabinoids AND S. mutans," "Cannabidiol AND oral health," and "Cannabidiol AND oral biofilm." The search was conducted in PubMed, Cochrane, and EBSCO Host databases. The search yielded a total of 73 articles, out of which 15 articles (20.5%) were relevant to the scope of this systematic review. Among the relevant articles, only eight (10.9%) directly addressed the research question. The findings from these articles suggest that cannabinoids have the potential to reduce the metabolism of cariogenic bacteria, specifically Streptococcus mutans, and decrease the number of bacterial colonies in dental plaque. In vitro studies also demonstrated a significant inhibitory effect of cannabinoids on oral biofilms and create a considerable inhibitory zone of growth when investigated on oral biofilms in vitro. Furthermore, CBD exhibited antibacterial properties against Porphyromonas gingivalis, a primary pathogen associated with periodontal disease. The current review shows insufficient data to conclude on the anticaries and antigingivitis effects of cannabinoids. Despite extensive research on their systemic therapeutic benefits, their oral health impact remains underexplored, lacking clinical trials and primary research.

The Pancreas Can Take the Cold: Lower Waitlist Times Through Importation

BACKGROUND

Our center has used a strategy of pancreas importation owing to long regional waitlist times. Here we assess the clinical outcomes and financial considerations of this strategy.

METHODS

This was a retrospective observational cohort study of patients who received a pancreas transplant at Montefiore Medical Center (MMC) from 2014 to 2017 (n = 28). Clinical parameters, including hemoglobin A_1c and complications, were analyzed. The cohort was compared with United Network for Organ Sharing (UNOS) Region 9 with the use of the UNOS/Organ Procurement and Transplantation Network database. Cost analysis of length of stay (LOS), standard acquisition (SAC) fees, and transportation was performed with the use of internal financial data.

RESULTS

Pancreas importation resulted in significantly shorter simultaneous pancreas kidney transplant waitlist times compared with Region 9: 518 days vs 1001 days (P = .038). In addition, postoperative complications and 1-year HbA_1c did not differ between groups: local 6.30% vs import 6.17% (P = .87). Patients receiving local pancreata stayed an average of 9.2 days compared with 11 days for the import group (P = .36). As such, pancreas importation was associated with higher mean charges ($445,968) compared with local pancreas recipients ($325,470).

CONCLUSIONS

Long waitlist times in Region 9 have encouraged our center's adoption of pancreas importation to address the needs of our patient population. This practice has resulted in a reduction of waitlist times by an average of 483 days. Understandably, centers have long been wary of importation owing to perceived risk in clinical outcomes. In our single-center experience, we have demonstrated equivalent postoperative glucose control and graft survival. Importantly, there does appear to be increased costs associated with importation, which are mainly driven by LOS. Curiously, importation from regions with lower SAC fees has the potential to offset costs related to transportation expenses. Notwithstanding these findings, pancreas importation does have the potential to lessen the financial societal burden through reduction in waitlist times.
