Results 15-year-old group is significantly higher than 12-year-old group in gingival bleeding detection frequency; dental calculus detection frequency and average section count.───结果：两个年龄组的牙龈出血检出率、牙石检出率以及牙石平均区段数，15岁年龄组明显高于12岁年龄组。
detection rates of gingival bleeding, dental calculus, periodontal pocket and periodontal attachment loss were 93.───牙龈出血、牙石、牙周袋、牙周附着丧失的检出率分别为93。
Objective: To observe the crystal character of the attached end and free end of dental calculus.───目的：观察牙结石附着面和游离面晶体构型的差异。
Dental care: Through removing dental plaque and dental calculus, prevent dental decay, make periodontal problems barely happen.───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。
Because dental calculus is more likely to cause the accumulation of dental plaque, causing gingivitis, periodontal disease.───由于牙石更可能导致牙菌斑堆积，造成牙龈炎，牙周病。
more teeth in the dental calculus, gingival recession more serious, it is recommended to the formal scaling of hospitals and clinics.───中，牙石牙龈萎缩更严重的牙齿，建议到医院和诊所的尺度。
Suitable hardness of granules, maintains oral hygiene and delays the formation of dental calculus.───颗粒硬度适合清洁口腔卫生延缓牙结石形成。
The detection rates of gingival bleeding, dental calculus, periodontal pocket and periodontal attachment loss were 93.───牙龈出血、牙石、牙周袋、牙周附着丧失的检出率分别为93。
