摘　　要：目的研究人工种植牙龈下中间普氏菌(Prevotella intermedia,Pi)1年内的数量变化情况,为种植体的定期维护提供理论基础。方法于2010年6月到2011年6月,对在山西医科大学第一医院口腔科门诊已完成固定义齿修复的38例患者的46颗人工种植牙进行为期1年的复诊检查,记录修复后1、3、6、12个月4个时段,所有种植牙的菌斑指数(PLI)、牙龈指数(GI)、牙龈出血指数(GBI)、探诊深度(PD)以及X线骨吸收情况,并采用Pi的选择性培养基对龈下菌斑标本进行分离培养,计算每毫升标本原液的菌落形成单位(CFU/mL)。结果随时间延长,种植牙周Pi检出量不断增加,1个月到3个月时增加的趋势最为明显,到6个月左右趋于稳定,其统计值在1个月和3个月、3个月和6个月间比较,差异有统计学意义(P<0.05),但在6个月和12个月间比较,差异无统计学意义(P>0.05)。PLI、GI和X线骨吸收值在修复后1、3、6、12个月比较,差异均有统计学意义(P<0.05)。GBI和PD仅在1个月和3个月间比较,差异有统计学意义(P<0.05),其余各时段间比较,差异均无统计学意义(P>0.05)。结论在临床工作中,应注意加强修复后3个月时种植患者的口腔维护,防止种植体周围炎的发生,提高种植成功率。Objective To study the changes of PrevoteUa intermedia Pi of the implants within one year. Methods Forty-six implants of 35 patients were collected. In the four stages of one month, 3 months, 6 mouths and 12 months after restoration, evaluate their Plaque Index （PLI）, Gingival Index （GI）, Gingival Bleeding Index （GBI）, Probing Depth （PD） and X-ray bone absorption. Subgingival plaque samples were cultured separately by the selective medium of Pi. Results As time went on, the value of Pi was increasing. From the 1 st to the 3rd month, the value increased most obviously and by the 6th month it became stable. The value of Pi was statistically different between the 1st and the 3rd month, the 3rd month and the 6th month, and showed no statistical difference between the 6th and 12th month. PLI, GI and X-ray bone absorption were statistically different among 1st, 3rd, 6th and 12th month （P 〈 0.05） ; the GBI and PD was significantly different between the 1 st and the 3rd month （P 〈 0.05）. Other tested indexes showed no statistic difference （P 〉 0.05）.Conclusion Patients with implants should be guided to do cleansing and maintenance in oral cavity after 3 months of restoration, so as to prevent peri-implantitis and increase success rate of implants.
