  patient: Nurse , my gums bleed when I brush my teeth . I don't know why .

  nurse: How long has it been like this?

  P: For about 5months.

  N: Open your mouth . Let me have a look There are a lot of dental calculus and odontolith on your teeth . They can stimulate the edge of the gums and cause inflammation and bleding of the gums.

  P: What are dental calculus and odontolith?

  N: The dental calculus is the soft calculs on the surface of teeh or at the edge of gums . It appears yello or grey . It's soft and easy to remove . The odontolith is the hard calcified or calcifying lump which is mainly formed by dental plaque . It's hard and dificult to remove.

  P: How to remove the dental calculus and odontolith?

  N: The doctors can do it . They remove them with a special instrument or an ultrasonic scaler.

  P: That's wonderful . Could you please say something more about ultrasonic curettage?

  N: Ultrasonic curettage is an effective method of debridement of the soft tissue walls of periodontal pockets , and histological studies of tissue excised after curettage have shown that healing occurs by epithelialization of the sulcuar surface and resolution of inflammation in the gingival corium . The ultrasonic technique is equally as effective as conventional hand instrumentation in calculus removal , but less effective in stain removal . Of course it is more rapid than hand instrumentation.

  P: Have you found any adverse effects on the tissue of the periodontium?

  N: No.

  P: Can we prevent dental calculus and odontolith?

  N: The most important thing is to pay more attention to dental hygiene . Especially you should learn to brush your teeth correctly.

  P: I brush them horizontally.

  N: That's a wrong way . The correct way is to brush them up and down . To brush them horizontally may rub all the natural enamel off . I think it is also very important to select a suitable toothbrush . The head of the toothbrush should not be too long or too short .For adults , the length of the head of the brush is not more than 35mm , the width is not more than 13mm . For children , the length is not more than 28mm , the width is not more than 11mm . For infants , the length is ont more than 25mm , the width is not more than 8mm.

  P: I have learned a lot . Thank you very much.

  N: Not at all.

  P: I want to have my teeth cleansed . Could you make an appoinment for me ?

  N: All right . The doctor has got rather a full day tomorrow , You can come here at 10 the day after tomorrow.

  P: All right . Good bye.

  N: Good bye.

  病人:护士,我刷牙时牙龈出血,不知道是什么原因?

  护士:这种情况有多长时间了?

  病人:大约有5个月了。

  护士:张开嘴,让我看看。… 在您的牙齿上有很多牙垢和牙石。它们可以刺激牙龈的边缘而引起牙龈发炎和出血。

  病人:什么是牙垢和牙石?

  护士:牙垢是附在牙齿表面和根缘处的软垢,呈黄色或灰白色,较软,易除去。牙石是附在牙面上的钙化或正在钙化的牙菌班为基质的团块。较硬,不易除去。

  病人:怎样除去牙垢和牙石呢?

  护士:大夫可以做到。他们用一种特殊的器具或超声波洁牙器来除去牙垢和牙石。

  病人:那太好了。您能再变谈超声波洁牙吗?

  护士:超声波刮治术是一种清扫牙周代软组织壁的有效方法。在刮治后的组织学研究表明:龈沟合,同时牙龈真皮内炎症得到消除。超声波技术清除牙石的作用与常规的手持器械同样有效,但除去色斑的效能较差,当然速度快得多。

  病人:你们发现它对牙周组织有害吗?

  护士:没有。

  病人:牙垢和牙石可以预防吗?

  护士:最重要的是注意口腔卫生。尤其是学会正确地刷牙。

  病人:我横着刷牙。

  护士:那是错误的方法。正确的方法是上下刷。横着刷可能破坏珐琅质。我认为选择一把合适的牙刷也是很重要的。牙刷头不可过长或过短。成年人刷头长度不超过35毫米,宽不超过13毫米。儿童,长度不超过28毫米,宽不超过11毫米。幼儿,长度不超25毫米,宽不超过8毫米。

  病人:我知道了许多知识。太谢谢您了。

  护士:不客气。

  病人:我准备洁齿,您能给我约定个时间吗?

  护士:好吧。医生明天已经排得相当满了。您可以后天上午10点钟来。

  病人:好吧,再见。

  护士:再见。
