Six weeks later, animals were treated with tamoxifen (15\u00a0mg\/kg) or saline, with further subdivisions receiving cisplatin (5\u00a0mg\/kg or 2.5\u00a0mg\/kg) or saline. A non\u2010ovariectomized group served as a negative control. Animals were euthanized at 30 and 90 days after treatment initiation. Tibiae were harvested for histometric analysis of bone\u2010to\u2010implant contact (BIC) and bone ingrowth (BIN), histology, and immunohistochemistry (tartrate\u2010resistant acid phosphatase [TRAP], osteocalcin [OCN], and runt\u2010related transcription factor [RUNX2]). Additionally, scanning electron microscopy (SEM) and energy\u2010dispersive X\u2010ray spectroscopy (EDS) were used for ultrastructural and elemental analyses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The groups that received TAM showed higher BIC and BIN, increased expression of RUNX\u20102 and OCN, and a lower number of TRAP\u2010positive cells. At 30 and 90 days, almost all spaces were filled with vital, well\u2010vascularized bone tissue without inflammatory foci. TAM groups also exhibited an increased calcium\/phosphate (Ca\/P) ratio compared to their respective controls, and a progressive thickening of collagen fibril bundles was observed in the bone matrix.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Tamoxifen positively influenced bone remodeling around osseointegrated titanium implants in rats undergoing cisplatin\u2010based cancer therapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Plain language summary<\/jats:title>\n                    <jats:p>Dental implant surgery in patients undergoing chemotherapy is frequently approached with caution, as these pharmacological treatments can impair bone metabolism and jeopardize the integration of the implant with the bone. This study investigated whether tamoxifen, a medication widely utilized in breast cancer therapy, could potentially enhance bone healing around titanium implants, specifically when administered alongside the chemotherapeutic agent cisplatin. Utilizing a laboratory model that simulates postmenopausal bone loss, the research demonstrated that tamoxifen significantly improved both the volume and the structural quality of the bone surrounding the implants, partially mitigating the adverse effects associated with cisplatin. These findings are of clinical importance as they suggest that a history of chemotherapy should not be considered a definitive barrier to successful dental rehabilitation. Instead, with appropriate pharmacological support, dental implant procedures may be a more viable and predictable treatment option for cancer survivors than previously recognized. This research provides a foundation for clinicians to better evaluate the feasibility of oral rehabilitation in this patient population, ultimately aiming to improve their long\u2010term oral health and quality of life.<\/jats:p>\n
