this is one of the more meaningful things i had done over the hols so far.. have long wanted to post this up but must wait for the correct timing (for may2 to receive this in singapore)..

meaning of this pix: me being secretive, behind elmo (hope u guys can roughly figure out by my hairstyle that the random person behind elmo is me ).. n my sis really likes elmo.. n this is the first time i draw my sis.. ahha.. took me abt 1/2 day drawing.. i'm really too slow.. tsk tsk..

n thanks to kriz, clara and xiang jun.. got a sweater from singapore from them.. (the postman knocked on the door so loudly this morning while I was still in bed, but i couldn't be bothered to open the door).. and the postman actually managed to squeeze the parcel into the small letter box we had in outside our house.. ahha. hmm.. a couple of days to becoming 21..

Worthy experiment subject

finally, sth interesting during this hols. today went for this experimental thingy which i volunteer as a experimental subject. actually xy and peng also volunteered, but we had different timing for the experiment, so i was alone.


i filled in some forms without really understanding what's the experiment was about, cos i could see shazia (the experimenter) was really eager to start.. she first asked whether i had put on any moisteriser on my face.. (OS: was my face that dry, or peeling and she was commenting on my facial condition?? oh gosh!!).. i answered "no" in quite an embarrassed manner. then she said "good, if u have u need to wipe it off cos it will interfere with the electrode conduction".. (OS: phew -__-").. and then i had to use the alcohol wipe to clean the area on my face where the masseter and thyrohyoid muscles are located, which are in front of the ear and where my double chin is respectively..


after adjusting some devices, she got me to sit down..


"I got some sand paper and i need to sand your face"


(OS: nani??!!)


then she just rub the sand paper against my face in front the ear and my double chin area..


(OS: don't disfigure my face pls..-_____- ")


then she wipe the area with alcohol and stick on the electrodes.. (OS: may be it's a good thing not to look at it..)


then there were some technical stuff going on (taking of impression, adjusting the bite block etc).. the dentist (i didn't get his name) cum shazia's supervisor came.. i did some exercises like clenching and chewing.. the chewing was really really tiring.. i think i chewed for 2-3min continuously at marching speed.. n it's not like chewing chewing gum. the strength involved was more like chewing on an apple.. n towards the end i could feel that my lower incisors had biten through the impression material onto the metal biting plate.. some abrasion must have occurred and crown height lost.. but i had to b cooperative.. the fact that the two of them were counting down the number of minutes left did not really help.. it was just very tiring.. but it was over.. shazia was commenting that my chewing was very strong (which is sth i don't know whether i should be proud of) but then shazia was telling the dentist she could find my data which she had just collected from my chewing, and the dentist was saying, mayb it's faster to redo it then to look for it.. (OS: NNOOOOnoonooo!!!). but luckily she found it, and my masseter muscles were spared..


then i did clenching again, but this time i need to clench very stably. there was this screen in front of me, i had to look at it to check that i clenched stably such that a white matched with a red line.. wow, it's really hard to explain.. but this was tiring too.. n i could feel some sensation on my lower incisors, like i was wearing braces..


and then the interesting part.. INJECTION!! the dentist, too, was eager to get me jabbed.. personally, i don't find it daunting, cos last time i had 4 premolars taken off, n thus had got a few jabs.. i was told to lie on the sofa (dental chair??) and shazia was holding a torch light (operator light??).. (OS: where's my bib n safety glasses?? i think i need suction??) i couldn't remember abt the dentist's infection control.. but then they start asking me abt somethings in singapore such as food, national service and my orthodontic tx.. (OS: ah ha, distraction technique to calm a patient sia, i know what u both are up too, but i'm not nervous what -_________-"). then came 4 small jabs.. which i felt some sensation, but it was bearable.. and just when the dentist was going to give the proper anaestheics, i could feel tears coming out from my right eye.. and shazia fetched me some tissues.. (OS: erm, i'm not crying.. the tears just came sub-consciously). n the dentist said jokingly, "oh, pls don't cry". (OS: -_________- '""). then he gave me another 4 shots and then 1 last shot on the palate behind the upper incisors, which wasn't as painful as i thought.. felt quite numb.. barely felt anything. (OS: i'm so going to drool like a 3 year old.. )


then a 5th year student came in, whom i think was here to help with the experiement.. (OS: oh gosh, another person to witness how i'm going to drool..).


then i did the clenching and chewing again.. tiring sia.. was trying to be rhythemic in my chewing (i was thinking abt tank's song to keep me in pace) n i was concentrating very hard to match the white line with the red line.. subconsciously, i was worrying whether i was drooling.. (i am well-known by my clinic partner to have a excellent, unlimited salivary flow).


finally everything was done.. n when i moved my mouth from the bite block, saliva flowed like nobody's business.. n i think some landed on my jeans.. (OS: argh!!!!!! -__________-", super embarrassing).. pple passed me tissues.. (OS: sigh sigh sighz..)..


then they arranged an appointment for me to have my radiograph.. then the 5th year student asked for my birthday cos he needed to fill in the form.. then shazia discovered that my birthday was next week.. then she passed me the form for the radiograph-taking n said "this is for you as an early birthday present". (OS: diaoz, thanks.. -___________-")..


ok, my lips felt like 2 sausages.. n i totally couldn't feel anything.. i'm so afraid saliva will flow out without me noticing, n it will be super embarrasing.. actually i wanted to do some grocery shopping but i thought better not.. then i chosed to walk the more remoted way home to avoid the crowd..


hopefully i will get my remuneration soon.. btw, xy din finish the experiment n din get the injection cos the device wasn’t working properly.. but she still got some $$.. mayb it’s a good thing..


interesting, really interesting.. -_____- "

the lower canine.. see the differences between this n the upper canine??

these are the front and back view of the upper right canine. but in human, in partiular in those who brux (me), the cusp tip will be worn off..

characteristics to note: M slope of incisal edge is shorter than distal slope. that's why the cusp tip seems more mesially placed. M-I angle is sharper than D-I angle. M contact point is lower than distal contact point. the incisal margin occupies 1/3 to 1/2 the height of the crown (this is the best way to distinguish the upper canine from the lower canine). on the Li aspect, cingulum is prominent and 2 shallow and concave lingual fossae on either side of the lingual ridge. root is distally placed. proportion is impt yeh..

i'm not crazy abt teeth. i just happen to have the urge to make a drawing of 16 (aka upper first molar).. the occlusal view.. i think the fellow dent students will know we need to know how to draw all 32 teeth, not in this fancy, artistic way, but to capture all the details.. so, since i'm free and have nothing better to do, i think this'll be a good way of killing time n revising..

i was msn-ing my sis.. i can't believe that she's actually in 3 rd year now.. so fast.. n i had only finished a 1/4 of my second year.. but anyway, back to her. today is her first day of sch after a ridiculously short break after exam, and she had to start seeing pt.. but b4 that she need to screen (which is to select) pt for her clinic session. so my mum was there to be screened..

not surprising, she has got periodontitis. the pocket depth on her 41(aka lower right front tooth) is 6mm.. why not surprising?? actually she has been saying that tooth got problems and causes pain.. but the "TWO, good, dentist-to-be daughters" can't do (or didn't) do anything to solve her problems.. anyway, she can only be treated by my sis a few months later because she needs to start with easier cases like patients with gingivitis. so for today, she did polishing for my mum.. n then she discovered there are a lot of food stuck in my mum's mouth.. and she tried to remove them.. (not trying to embarrass my mum, but i think me and my sis like digging n removing these things from pple's mouth)..

it's good that my sis will get relatives and friends to be her patient. it's not as stressful dealing with someone we know.. poor me, going to see pt in the later part of the year, but i don't have a single family member here.. i think i will be so gan jiong (panic) when i see my pt.. but i'll pretend to be confident ba.. n like what me n my sis pointed out, everything, including professionalism, comes with practice n time..

sth to share..

if you haven't realised, that's me, drawn by my equally-talented (or more talented) twin sis.

this is by me. drew it long time ago. it's hanamichi sakuragi and his gang from Slam Dunk (my fav comic).

it's team shohoku..

thinking about it, i had drawn my mum, EP, peng, sara, han and some friends back in singapore etc.. hopefully next time at any special event (i.e. my memorial -which i hope won't be too soon), i can have a small exhibition. err..ok.. hope u all enjoy..

today was quite eventful. bought my study desk.. $45, a decent one compared to what i used to have at hume st.. and was transported home by a reckless taxi driver.. and lab was "strenous" as ususal.. and finally, my blog managed to have a make-over (a major one).. will put up more things soon.. (i hope).. haven't touch dlp yet.. tsk tsk.. think i'm getting addicted to blog designing, spent so much time on it.. gtg zzz now @_@.
