2) Root Planning
根面平整
1.
S group were treated with supragingival scaling; P group were treated with scaling and root planning.
目的：观察并比较洁治术与根面平整术对中度慢性牙周炎(chronic periodontitis，CP)患牙最大咬合力和牙周临床指数的改善程度，提示医患双方重视、坚持系统的牙周治疗。
3) Planar root channel
平面根槽
4) root planning
根面平整术
1.
METHODS:Two hundred sixty-six periodontally compromised teeth from 53patients(126 teeth with light-grade periodontitis and 160 teeth with severe-grade periodontitis)were treated,with PERIO locally(experimental group) or with systematic administration of antibiotics(control group),after routine root planning.
方法:对53名患者的266个患牙(其中轻度牙周炎106个,重度牙周炎160个)行常规根面平整术后配合局部使用派力奥(实验组)或配合全身用药(对照组),记录比较各项临床指标。
2.
Method: 4 teeth in 20 patients with moderate to advanced periodontitis were randomly divided into four groups: ①minocycline plus scaling and root planning(SRP+M) ②scaling and root planning alone(SRP) ③minocycline alone(M) ④untreated group(U).
结论 :龈下局部应用米诺环素联合刮治术和根面平整术在降低探诊深度和探诊出血方面比单纯实施刮治术和根面平整术组效果明显。
3.
After subgingival scaling and root planning,the test(Fluor Protector)and placebo agents were randomly applied on the root surface.
方法:选择中重度牙周炎病人20例(114个)作为临床分析对象,进行洁刮治和根面平整术后,采用双盲法分别应用氟保护漆和安慰剂涂布根面。
5) rot planning
根面平整治疗
6) rooted planar map
有根平面地图
1.
Based on duality principle, the enumerating equation of undetachable-edge rooted planar map with face partition is extended, obtaining an enumerating equatim whose explicit equation, with number of edges being parameter, is derived by means of quadric form and lagrange inversion theorem.
得到了无环有根平面地图依节点剖分的计数方程 。
2.
Another class of special rooted planar maps-the pentagons is analysed,and the relative results are obtained.
作者在文献[2]、[3]中对三角形与四角形剖分地图进行了讨论，得到了其以根面度数与非极面个数为计数参数的计数方程；对另一类特殊的有根平面地图无重边近五角剖分地图进行了分析，得到了相应的结果。
补充资料：根面角
根面角，是陕西的一道风味小吃，形似半月，呈浅褐色，每联5瓣。据传是由当地传统素筵中分化出来的。初为清香型，流行既久，又转为浓香型，从而素与荤两种并列。其主要原料系从野生蕨根中提取的淀粉作皮，以鲜蔬作馅，急火蒸成，然后再蘸上酸辣之汁。本为夜宵小吃，现在也逐渐登上豪华宴席。
