The purpose of this pilot study is to conduct a interventional prospective clinical trial to evaluate the efficacy of three different xenografts for ridge preservation by comparing the quality of newly formed bone using histomorphometric and micro CT analysis.The three xenograft materials under investigation are Bio-Oss® (bovine derived xenograft), Equimatrix® (equine derived xenograft), and Endobon® (bovine derived xenograft). There are no prospective studies comparing the effectiveness of these three materials, Bio-Oss®, Endobon® and Equimatrix®, when placed in extraction sockets. Participants will be recruited from patients in the TUSDM clinics that require extraction of single rooted non-molar tooth and are treatment planned to receive dental implants in the future. Participants will be randomized to receive one of the three xenograft materials after tooth extraction. The percentage of newly formed bone and bone density will be compared between the three materials 4-6 months after ridge preservation.

The purpose of this research study is to find out whether Maca Root is effective for treating sexual dysfunction in females that is caused by the treatment for bipolar disorder. An additional aim of the study is to document the safety and tolerability of maca root, as well as any potential side effects that it causes. We suspect that Maca Root will result in a significant reduction in sexual dysfunction when compared to a placebo group.
