　　3Presentation 0f Treatment Plan I
　　Dr Samson：Mrs Wu，I‘ve now completed the examination and the x．rays films havebeen developed．Let me just double．check your teeth and gums with the x．rays．
　　Mrs Wu：Okay，doctor．
　　Dr Samson：I can see there are a couple of cavities in your teeth that require someattention．According to the x—ray．one of them seems to be very deep and might affectthe nerve inside the tooth．There’s also a broken old filling in one of your upper frontteeth．That needs to be replaced．However，before we start on the fillings，you willneed to see the hygienist to have your teeth and gums cleaned．
　　Mrs Wu：Is it necessary to have my teeth and gums cleaned？I don’t feel any painfrom them．
　　Dr Samson：I know you’re probably not suffering any pain but I can see that someareas of your gums are red and swollen and that’s usuaUy due to problems in cleaningthose areas．Also，some of your teeth are stained，probably from tea，and there are mul．tiple deposits of tartar around your teeth．
　　Mrs Wu：Can I delay the cleaning to a later date？I‘d prefer to have the fillings donefirst．
　　Dr Samson：丁hat’s possible but 1 would advise against it．The reason why I‘d recom．mend cleaning the teeth and gums first is to improve the condition of your mouth and it’IImake providing the fillings an easier task．
　　Mrs Wu：Okay．I have 2 other questions．What sort of material are you going to useto replace the broken filling in my upper front tooth？1 want the fmal result to look nice．Secondly，you said one of the cavities is very deep and might affect the nerve．Does itmean you’U have to pull the tooth？
　　Dr Samson：I‘ll use a tooth．coloured material to replace the broken filling and thenew filling will look like part of your tooth．Even if the nerve is affected by dental de．cay，we don’t have to extract the tooth if you want to save it．We can save the tooth bycarrying out root canal treatment but a crown is required afterwards．
　　Mrs Wu：7hank you for taking the time to answer all my questions，doctor。Presentation of Treatment Plan II
　　Dr Quinn：Mr Ryan，you can probably guess that the state of your teeth is not verygood．After examining your mouth，I can say that you need extensive treatment if youwant to eliminate all the dental diseases in your mouth．
　　Mr Ryan：Yes，I have been aware that my teeth are in a poor condition for sometime．Can you please tell me what sort of treatment is needed？I‘d like to save as manyteeth as possible．
　　Dr Quinn：First of all。you’11 need to visit our hygienist．She’U help you to improveyour oral hygiene standard as well as spending a few sessions Cleaning your teeth andgums．There are four back teeth which are hopeless and I recommend their extraction assoon as possible．Then the cavities inside your teeth will be restored and I think twoteeth which have deep decay will need root canal treatment and crowns．Also，some sortof replacement will be required to fill in the gaps left by the extracted teeth．
　　Mr Ryan：That sounds like a lot of dental treatment．Could you tell me more aboutreplacing the hopeless teeth？
　　Dr Quinn：To replace missing teeth，we could construct dentures，bridges or useimplants．I have some leaflets here explaining each option．Please take one home toread and let me know if you have any questions at your next appointment．
　　Mr Ryan：7hank you．As I need SO much dental treatment．I‘m worried about thecost involved．Could you give me an estimate on the cost and what are the arrangementsfor payment？
　　Dr Quinn：I understand your concern．If you like，I’ll provide you with a breakdownof the treatment cost．As for payment，you can pay as you go along．Our office acceptscash，the usual credit cards and cheques．
　　4Treatment．Simple Operative Procedures
　　Dr Jacobs：Good morning，Johnny．How are you today？
　　Johnny：I‘m fine，thank you．
　　Dr Jacobs：Did you go to school this morning？
　　Johnny：Yes，I did but I had to leave school early in order to come here．what areyou doing to me today？
　　Dr Jacobs：You remember I looked at your teeth last week，don’t you？I saw a littlehole in one of your upper back teeth and I‘ll need to clean it and put a small filling inthere．Otherwise，the hole will get bigger and bigger．
　　Johnny：Is it going to hurt？
　　Dr Jacobs：I’ll need to numb the gums and tooth with some special paste and asmall injection．Once the tooth is numbed．it won’t feel any pain．wiu you let me dothat？
　　Johnny：I suppose SO．However，I‘d like to hold my mother’S hand．
　　Dr Jacobs：No problem．Mrs Lawrence，can you hold Johnny’S hand，please．
　　Mrs Lawrence：0kay，doctor．
　　Dr Jacobs：Johnny，now I am going to put some paste on the gums next to thetooth．The paste will make the gums go a bit numb．Keep your mouth open and don’tput your tongue up there as the paste tastes a bit strange．
　　（after 1 to 2 minutes）
　　Dr Jacobs：I‘m now going to numb the tooth further，just keep still．I have to dothis part slowly and you won’t feel anything．You might want to squeeze your mother’Shand a little．
　　（after injection）
　　Dr Jacobs：Have a quick rinse and we’ll have to wait a few minutes for the tooth togo numb．
　　（after 3 to 4 minutes）
　　Dr Jacobs：Does your cheek feel a bit funny and swollen？
　　Johnny：Yes，it does．It feels really strange．Do I look swollen up？
　　Dr Jacobs：No，you look quite normal．It is just the feeling that is different in thatarea．This will go away after around 2 hours．Mrs Lawrence，please make sure Johnnydoesn’t bite his cheek accidentally after you leave here．
　　Dr Jacobs：Johnny，I‘ll start cleaning the tooth with the small hole．You’11 hear a lotof noise and you might feel some vibrations．There’ll be lots of water splashing aroundinside your mouth．My nurse will help me by sucking out all the water with this suctiont杠If you can keep your mouth wide open and keep still，it will aU be over very quickly．
