Community-based medication disposal pilot initiative in southwest tribal communities.

BACKGROUND: Misuse and abuse of prescription drugs including opioids has been a driving force behind the drug overdose epidemic plaguing communities across the USA for more than two decades. Medication accumulation in the home environment can contribute to this issue. However, research on proper disposal in rural communities is limited. For this project, an applied public health approach was used to raise awareness and improve prescription drug disposal practices by pilot testing prescription drug disposal systems in participating communities. METHODS: A community-based disposal project was facilitated with assistance from community partners. The project centered on distribution of drug deactivation bags in homes and medication drop boxes at multiple healthcare facilities. RESULTS: The team distributed 215 drug deactivation bags to 162 community households resulting in destruction of 8011 pills, 8 medicated dermal patches and 777 mL of liquid medication. A total of 4684 pounds of medication were collected and disposed of through healthcare facility drop boxes. CONCLUSION: The strategies identified are scalable and easy to replicate to meet any community's needs in reducing potential challenges of medication diversion.

The effect of a resin-based sealer on crown retention for three types of cement.

STATEMENT OF PROBLEM: In an effort to control postoperative sensitivity, dentin sealers are being applied following crown preparation with little knowledge of how crown retention might be affected. A previous study demonstrated no adverse effect when using a glutaraldehyde-based sealer, and existing studies have shown conflicting results for resin-based products. PURPOSE: This study determined if a resin sealer applied to prepared dentin affected retention of cemented castings when using 3 common types of luting agents. MATERIAL AND METHODS: Extracted human molars (n=55) were prepared with a flat occlusal, 20-degree taper, and 4-mm axial length. The axial surface area of each preparation was determined and specimens were distributed equally among groups (n=11). A 2-step, single-bottle adhesive system (One Step) was used to seal dentin following tooth preparation. Sealer was not used on the control specimens except for the modified-resin cement (Resinomer) specimens that required use of adhesive with cementation. Using ceramometal high noble alloy (Olympia), a casting was produced for each specimen and cemented with a seating force of 20 Kg using either zinc phosphate (Fleck's), glass ionomer (Ketac-Cem) or modified-resin cement (Resinomer) with the single-bottle adhesive. Castings were thermal cycled at 5 degrees C and 55 degrees C for 2500 cycles; then removed along the path of insertion using a universal testing machine at 0.5 mm/min. A single-factor ANOVA was used with alpha=.05. The nature of failure was also recorded and the data analyzed with a chi-square test. RESULTS: Mean dislodgment stresses for unsealed and sealed conditions were 3.7 +/- 1.0 and 2.2 +/- 0.8 MPa for zinc phosphate; 2.7 +/- 1.2 and 4.2 +/- 0.9 MPa for glass ionomer, respectively (P<.001). Retentive stress of castings cemented with modified-resin cement was 6.4 +/- 1.7 MPa. With resin sealer in combination with zinc phosphate, cement resided totally on castings in 82% of the situations and was on both surfaces without sealer. The tooth failed before casting dislodgment in 9 of 11 specimens cemented with modified-resin cement. CONCLUSIONS: Resin sealer decreased casting retentive stress by 42% when used with zinc phosphate. However, sealer use resulted in 55% increased retention when used with glass ionomer. The modified-resin cement produced the highest mean dislodgment stress, nearly always exceeding the strength of the tooth.
