Laser-Mediated Hemostasis for Older Patients Receiving Routine Dental Treatment

TL;DR

Laser therapy helps stop bleeding quickly and promotes healing in older dental patients.

Contribution

Demonstrates laser-mediated hemostasis as an effective and safe method for older patients in routine dental procedures.

Findings

Laser therapy achieved rapid hemostasis in 97.86% of bleeding events.

Photobiomodulation alone was most effective for soft tissue hemostasis.

Full recovery of extraction sockets was observed within 2-4 weeks.

Abstract

Background/Objective: Laser therapy has gained attention in dental practice to minimize bleeding and enhance blood clot formation. This study aimed to explore the utilization and to compare the clinical efficacy of laser-mediated hemostasis for older patients receiving routine dental treatment. Methods: A prospective observational study was conducted across research networks between October 2023 and August 2024, involving 60 patients aged 50 years and older (average = 63.35 years) at risk of postoperative bleeding following dental treatments. Additionally, laser therapy for hemostasis was selected and provided among calibrated operators. A single researcher performed data collection. Before statistical analysis, data verification and clinical assessment were conducted by the operators and researcher. A clinical cut-off for hemostasis was set at 5 min. Two diode laser machines were used namely, an 810 nm and dual wavelengths of 635 nm and 980 nm. Results: There were 94 extraction sockets, 28 procedures of scaling and root planing and 18 procedures of minor oral surgery. Combining laser ablating sulcular fiber and photobiomodulation initiating blood clot formation was a preferable hemostatic technique for extraction socket, while photobiomodulation alone was a preferred technique for soft tissue hemostasis (p < 0.001). All operators confirmed that 97.86 percent of bleeding events achieved more rapid hemostasis. 61.43 percent of bleeding events clinically achieved hemostasis within 5 min by using laser-mediated hemostasis alone (p = 0.092). Full recovery of the extraction socket was significantly observed during the 2- to 4-week follow-up period (p = 0.005). No clinical complications were reported. Conclusions: Laser-mediated hemostasis effectively reduced hemostatic duration, prevented postoperative bleeding and promoted wound healing in older patients undergoing routine dental treatment.
