introduction: laser surgery as an alternative for conventional surgical procedure has gained special attention. using carbon dioxide (co2) laser has some benefits like less post-operative pain, swelling and infection, decrease in risk of metastasis and edema, and less bleeding providing dry sites for surgery. case report: a 12 years old boy with lingual frenum with indication for excision was r...

introduction: epulis fissuratum is often formed as a result of a poor fitting denture. the conventional treatment for this fibrous hyperplastic tissue is to excise it using a scalpel and to close the wound by a continuous or an interrupted suture. the increased utilization of lasers in dentistry also includes the utilization of carbon dioxide (co2) lasers in place of surgical scalpels in soft t...

introduction: the purpose of this study was to investigate the effect of 6w power carbon dioxide laser (co2) on the biologic compatibility of the sandblasting with large grit and acid etching (sla) titanium discs through studying of the sarcoma osteogenic (saos-2) human osteoblast-like cells viability. methods: sterilized titanium discs were used together with saos-2 human osteoblast-like cells...
