牙结石

牙结石体外溶解及再沉积的实验研究

Experimental Study on Dissolution and Re-deposition of Dental Calculus in vitro

犬龈上牙结石的傅立叶红外光谱分析和扫描电镜观察

SEM observation and FTIR analysis of canine dental salivary calculus

离体牙结石溶解性的研究

Study on the solubility of dental calculus in vitro

龈上牙结石附着面和游离面晶体构型的扫描电镜观察

SEM observation of dental subgingival calculus in the attached end and free end

现在还不需要，但你的确需要清除牙结石和深部洗牙。

Not now . But you do need to have scaling and deep cleaning .

研究结果显示，当牙结石越严重时牙龈炎程度越严重，缺齿数也越多。

Gingivitis scores elevated with the calculi score and the number of teeth missing .

牙结石患病率为10.8%，牙龈炎患病率22.1%。

The rates of calculus dentalis and gingivitis were 10.8 % and 22.1 % .

目的：观察牙结石附着面和游离面晶体构型的差异。

Objective : To observe the crystal character of the attached end and free end of dental calculus .

50例龈炎患者龈沟出血与牙菌斑、牙结石、龈炎的关系

Relationship between Bleeding in the Gingival Sulcus and Calculus , Plaque and Gingivitis Index in 50 Cases of Gingivitis

健齿：通过清除牙菌斑和牙垢，减少蛀牙和牙结石的形成，牙周问题甚少发生。

Dental care : plaque and remove plaque through , reduce the tooth decay my teeth and formation of periodontal problem seldom happen .

用磁场影响牙结石重新附着可降低缘龈炎的复发率。

The recurrent rate of the marginal gingivitis can be decreased in a magnetic field that interferes with adhesive force of the dental tophus .

牙龈晦暗，不是牙结石太多，炎症较重，就是有血液系统疾病或者其它系统性疾病，也是需要注意的。

Dark gums , teeth are not too severe inflammation , there is blood diseases or other systemic diseases , but also need to pay attention .

他们的牙龈炎患病率为209%，牙结石患病率为582%，与地勤人员相比差异有显著性意义（P<001）。

The percentage of gingivitis and dental calculus in pilots were 20.9 % and 58.2 % , respectively , significantly lower than those of the ground crew ( P < 0.01 ) .

目的清除牙结石和减少及防止牙菌斑的再堆积是治疗牙周病，防止复发的主要措施，目前已知最切实有效的方法是机械清除菌斑及牙结石。

Objective The removal of calculus , decrease and prevention of the accumulation of plaque is the key to the treatment and prevention of recurrent of periodontal disease . The most known effective way is mechanical removal of plaque and calculus .

针对三种不同病因所引发的牙龈出血原因，可以通过治疗牙周疾病，去除牙结石以及及时补上龋洞的方式，治疗牙龈出血问题。

For three different causes of bleeding gums caused by reasons , can treat periodontal disease , removal of tartar and cavities on the way up in time , treatment , bleeding gums problems .

认为牙周疾病发病率高，其发病与牙菌斑、牙结石关系密切；

Suggested that periodontal diseases have a high morbidity , and there be a close relation between the onset of periodontal disease and dental plaque , odontolith .
