项目摘要

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犬根部牙本质后创面愈合的组织学研究：Er：YAG激光照射对牙周组织在牙本质上的附着无不良影响。2)大鼠骨激光消融后创面愈合的组织学研究：与机械烧伤相比，Er：YAG激光制备的骨缺损早期愈合更好。3)Beagle犬牙周瓣手术中Er：YAG激光清创病变结缔组织和根面后创面愈合的组织学研究：Er：YAG激光清创有效、安全，创面愈合与机械清创基本相同。组织学研究正在进行中。4)Er：YAG激光去除牙周黑色素或文身色素沉着的临床应用：不需要很大的手术就可以很容易地去除有色牙龈组织。热损伤，如凝结或碳化。使用水喷雾提供了清晰的操作范围，激光照射过程中的显微镜监测对彻底去除色素沉着有很大的好处。提示Er：YAG激光照射可以安全、有效地去除牙周色素沉着。
