hey there..

there is a table in nbde first aid regarfing overjet/over bite corralating with height of cusps//


large overjet small overjet

large overbite variable longest cusps

smalll overbite shortest variable

can someone pls explain me this concept and clinical corrolation like in a 5 year old?

tnx :-0)

 

[densindente]

A permanent mandibular canine can be distinguished from a permanent maxillary canine because, typically, the mandibular canine has: (a) a sharper facial cusp outline; (b) a straighter mesial border, when viewed facially; (c) contact areas located more incisaily; (d) a more pronounced cingulum; (e) a cusp tip displaced lingually to a midline faciolingually.

1. (a), (b) and (c)
2. (a), (c) and (d)
3. (a), (d) and (e)
4. (b), (c) and (e)
5. (b), (d) and (e)
6. All of the above

hi
i am not clear about this concept but it goes somehting like this

if overbite is more then there needs to be higher cusps to suffice for more length of overlap in anterior so that there is no damage to the anteriors in protruding movement

and if overjet is more then the cusps are less in height....

but make sure you read in again i am telling you off of my memory. it is in kaplan DA section

hey guys whats the corner stones of the arches??
isnt it canines acording to wheeler's.decks say it is molars..
what do i follow???

corner stones are from where something starts... like we inaugurate the making of the buildings lol... think on those terms and molars are starting of permanent dentition

Oxygen removal from the alveoli of the lung may be facilitated by

1. low PO2 of pulmonary artery blood.
2. increased total alveolar surface area.
3. increased blood flow through alveolar capillaries.
4. all of the above.
5. none of the above

ans given is all of the above...
can u help me wth ths Q..?/

1-true,due to conc gratient bw alveoli preuure 100mmhg to pulmonary a. 40mmhg of oxygen. 2 and 3 also contribute..think logical...more surface area more site for o2 transfer across membrane..

hi njsmahal,
i appreciate ur work... ur able to clear doubts for each q posted in sdn.i'm also having doubts , but my prob is i dont know hw to start a thread, so i'm posting them as quotes but not receiving replies (as i did now), so can u plz help me in this.....
my physio doubt...
1. The level of non-protien nitrogen in the blood is due principally to the level of -
asw: urea
my doubt is ? not Ammonia???😕 as it is d end product of protien metabolism......

2. which of the following hormone is a polypeptide
1. epinephrine 2. progesterone 3. FSH
4. testosterone 5. tri iodotyronine

thankful 2 u

actually ammonia is highly toxic to the body so even though it si produced it is converted into urea which is less toxic.


and for the second question this is what i found check it out

Several important peptide hormones are secreted from the pituitary gland. The anterior pituitary secretes luteinizing hormone and follicle-stimulating hormone, which act on the gonads, prolactin, which acts on the mammary gland, adrenocorticotrophic hormone (ACTH), which acts on the adrenal cortex to regulate the secretion of glucocorticoids, and growth hormone, which acts on bone, muscle, and the liver. The posterior pituitary gland secretes antidiuretic hormone, also called vasopressin, and oxytocin. Peptide hormones are produced by many different organs and tissues, however, including the heart (atrial-natriuretic peptide (ANP) or atrial natriuretic factor (ANF)) and pancreas (insulin and somatostatin), the gastrointestinal tract (cholecystokinin, gastrin), and adipose tissue stores (leptin).[4][5]

Some neurotransmitters are secreted and released in a similar fashion to peptide hormones, and some 'neuropeptides' may be used as neurotransmitters in the nervous system in addition to acting as hormones when released into the blood. When a peptide hormone binds to receptors on the surface of the cell, a second messenger appears in the cytoplasm, which triggers intracellular responses.[

thanks 4 ur reply😳
i found.... that

straight chain peptides n polypeptides - corticotrophs
glycoprotiens wt alpha n beta subunits - LH, FSH, TSH
straight chain peptides containing disulfide bridges - GH, prolactin

but ans is FSH 😕 help me

 

[gaya]

which is a nucleotide:
urate
uracil
adenosine
thymidylate
if there is ratio of bicarbonate-carbonic acid is 20:1,after sometime it will be 10:1,what do u say it is
1-compensate alkalosis
2-compensate acidosis
3-uncompensate alkalosis
4uncompensated acidosis

please explain me

tuberculum sextum is most commonly found on which tooth?
what is tuberculum sextum? i tried googling it but it wasn't very informative...

 

[ronu24]

the corner stones of the arches are the canines

i agree with this ..... corner stone: canine

hey friend i'm confusing in 3rd option....about supply

tuberculum sextum is most commonly found on which tooth?
what is tuberculum sextum? i tried googling it but it wasn't very informative...

some mandibular 1st molars have 6th cusp that is called tuberculum sixtum

blod flow through capiilaries means a platform where o2 duffuisionoccur via the Basment membrane..if blood wont reach the site of diffusion-->a shunt will occur.

3-uncompensate alkalosis
4uncompensated acidosis

please explain me

the new ratio states the less bicorbonte is seen,,it means the there was a shift towards the carbonic acid. a shif to the conjugated acid occur when high conc of H+ seen.. carobnic acid-->bicarbonate ion + h+ (we will see **** to the left)

so this acidosis.
now lets see if this compenstad or non compansated..
i think non compansated becasue the ration is still abnormal..but i think this questuin is too poor with info to distinguish bw compansated to non compansated...

acceptable plastic that can be used for steam sterilization or autoclave is
1.polypropylene
2.polystyrene
3.polyethylene
4.polyurethane
5.polyvinyl chloride

 

[gaya]

oh thank u for u r reply .please help me with these confusing ones
1 The distal inclination in roots of the permanent mandibular first molar is:
A. more pronounced in either root, depending on the tooth
B. usually more pronounced in the mesial root
C. usually more pronounced in the distal root
D. usually equal in both roots
At the cervical line, a cross section of the maxillary lateral incisor would show:
A. a round shape
B. an oval shape wider on the lingual than the labial
C. a triangular shape with a distinctly wider labial surface
D. an oval shape with a slightly wider labial surface
E. mesiodistal flattening
2.At the cervical line, a cross section of the maxillary lateral incisor would show:

Many plastic items for medical or laboratory use can be made from polypropylene because it can withstand the heat in an autoclave
