Ion objective : to investigate effect of nd : yag laser irradiating root canals on periapical tissue . methods : three minipigs were used in this study , deciduous premolars were opened , pulps were extracted , root canals were enlarged , then irradiated with nd : yag laser 30s and filled conventionally . the changes of periapical tissue were observed after 1 , 3 , 7 and 15 days . results : after one day , periapical tissue showed enlargement and engorgement of blood vessel and a few of leukocyte , the changes were more serious than in control . after 3 and 7 days , there were minor reactions in periapical tissue and same as the control group . after 15 days , periapical membrance in most specimens was normal . slight inflammatory reaction was found in the test group as same as in control group . conclusion : there was little damage to periapical tissue with the laser irradiation 目的:觀察激光在根管內照射后對根尖周組織的作用.方法:選3只小型豬,全麻下將乳前磨牙開髓、抽髓,根管擴大后,激光照射30秒,做常規根管充填.對照組為常規根管充填. 1天、 3天、 7天和15天后觀察根尖周組織的變化.結果:激光照射后1天,根周膜血管充血、輕度炎癥,對照組只有根尖周膜充血.激光組組織反應比對照組稍重.激光照射后3天和7天,少數病例根周組織有輕度的刺激與對照組的病理表現相近.激光照射后15天部分標本根周膜正常,部分標本有輕度炎癥反應,與對照組結果基本相似.結論:本激光照射條件對根尖周組織沒有明顯損傷作用,可供臨床應用時參考 |

Results : with three different retainer designs , the retainer on the second premolar and the first molar exerted the smallest stress on the abutment and its periodontal tissue , while the retainer on the first premolar and the first molar had the largest stress 結果：在3種不同的固位體設計方式中，固位體放置在第二前磨牙與第一磨牙之間時，基牙及牙周組織受力最小；固位體放置在第一前磨牙與第一磨牙上，基牙與牙周組織受力最大。 |
