Study on the application of the Er: YAG laser for periodontal flap surgery

1)Er：YAG激光照射Beagle犬根面牙本质后伤口愈合的组织学研究：Er：YAG激光照射对牙周组织在牙本质上的附着没有负面影响。激光治疗后的额外酸或机械治疗显示比单独激光治疗更好的愈合。2）大鼠Er：YAG激光骨消融后伤口愈合的组织学研究：与机械钻相比，用Er：YAG激光制备的骨缺损在早期显示更好的伤口愈合。3）Er：YAG激光后伤口愈合的组织学研究：Beagle犬牙周皮瓣手术中病变结缔组织和根面的YAG激光清创：Er：YAG激光清创有效、安全，伤口愈合与机械治疗基本相同。组织学检查正在进行中。4）Er：YAG激光去除牙龈黑色素或纹身色素沉着的临床应用：很容易实现色素牙龈组织的消融，而不会产生重大影响。热损伤，如凝结或碳化。在激光照射过程中，使用水喷雾提供了清晰的手术视野和显微镜监测，对完全去除色素沉着有很大的优势。结果提示：Er：YAG激光治疗牙龈色素沉着是一种安全有效的方法。

1) Histological study on wound healing after Er: YAG laser irradiation on the root dentin in Beagle dogs: Er: YAG laser irradiation did not negatively affect periodontal tissue attachment on dentin. Additional acid or mechanical treatment after laser treatment showed better healing than laser treatment alone.2) Histological study on wound healing after Er: YAG laser bone ablation in rats: The bone defect prepared with the Er: YAG laser showed better wound healing at an early stage, compared to that with the mechanical bur.3) Histological study on wound healing after Er: YAG laser debridement of the diseased connective tissue and root surface during periodontal flap surgery in Beagle dogs: The debridement with the Er: YAG laser was performed effectively and safely, and the wound healing was much the same as the mechanical treatment. The histological investigation is in progress.4) Clinical application of the Er: YAG laser for removal of gingival melanin or tattoo pigmentation: The ablation of the pigmented gingival tissue was easily achieved without major. thermal damage such as coagulation or carbonization. The use of water spray provided a clear operation field and microscopic monitoring during laser irradiation was of great advantage for complete remoal of pigmentation. The results suggest that the removal of gingival pigmentation can be performed safely and effectively by Er: YAG laser irradiation.
