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.

1）Er:YAG激光照射Beagle犬根部牙本质后伤口愈合的组织学研究：Er:YAG激光照射不会对牙本质上的牙周组织附着产生负面影响。激光治疗后附加酸或机械治疗比单独激光治疗有更好的愈合效果。2）大鼠Er:YAG激光骨消融术后创面愈合的组织学研究：用Er:YAG激光制备的骨缺损早期显示出更好的创面愈合。 3）Beagle犬牙周瓣手术中Er:YAG激光清创病灶结缔组织和根面后创面愈合的组织学研究：Er:YAG激光清创YAG激光治疗有效且安全，伤口愈合与机械治疗基本相同。组织学研究正在进行中。4)Er:YAG激光去除牙龈黑色素或纹身色素沉着的临床应用：色素性牙龈组织的消融很容易实现，无需太大的努力。热损伤，例如凝结或碳化。水喷雾的使用提供了清晰的手术视野，并且在激光照射过程中进行微观监测，对于彻底去除色素沉着具有很大的优势。结果表明，Er:YAG激光照射可以安全有效地去除牙龈色素沉着。
