17. which of the following explains why the z plasty techniques used in modifying a labial frenum is considered to be superior to the diamond technique

a. it is less trauamtic
b. it is technically easier
c. it requires fewer sutures
d. it increased the effect of scar contracture
e. it allows for closure by second intention

The main advantage of z plasty over the Vplasty method is minimal scar tissue formation.The method requires a skilled operator as it is tedious to perform.
so the answer is A

hey dds mania.. the answer is maxillary cuspid(C). The mandibular premolars(especially with mand 1st PM) are very inconsistent with their root canal anatomy.In fact the mand 1st PM is often called the enigma to an endodontist, although mand 2nd pm is more or less consistent in its anatomy.
Mand incisors have 2 canals in 40% of the cases. And in case of mand molars they have an additional distal canal, maxillary1st and 2nd second premolars may have 3 or 2 canals respectively.Sorry for the info overload..but i hope this clears ur doubts🙂

Amt of LA in 1.8 ml is 0.05/100*1.8*1000= 9 mg
Max dose is 30 mg
So, cartridge needed would be 30/9= 3.333
That makes ans 1-9
Is this the answer?

no answer is 28-36.

.05 x 10 = .5

.5x1.8= .9 approx 1mg / cartridge so to get 30 mg you need 30 cartridges.

please help me to solve this question, thx

if periodical radiolucency is present at the apex of a tooth with a middle third root fracture and the apical canal space is non-negotiable, the required treatment would be

1. extraction because of the port prognosis
2. calcium hydroxide treatment of the coronal segment only
3. apical surgery with a super EBA reverse filling
4. apical surgery with removal of the apical segment root canal treatment on the coronal segment
5. extraction with removal of the apical segment and replantation of the coronal segment

the answer is 5. Why?

Based on given question, root fracture with no RCT tx option due to the apical canal space is non-negotiable. I would first think about the goal of tx. If the tooth has a single root then extraction. but what if it is multi-rooted tooth then possible tx should be resection with removal of only affected root.

I agree with you. Mandibular premolar root canal morphology has the most variations and because of that it is very difficult to treat and high failure rate. if you see the words "mandibular first premolar", then think a "C-shaped canal anatomy".

Doubled rooted mandibular lateral incisor, so, i will eliminate the choice of the (a).
C-shped root canal variation find at mandibular molars, maxillary molars, and mandibular first premolar. so, eliminate the choices of the (c) and (e).
There is a variation on Maxillary second premolar. For this reason, access preparation of max second premolar can be same prep. as max first premolar. so, eliminate the choice of the (d).

I will answer (b)?
I should definitely look into this question when I go over the ASDA.

Hi All, currently studying for NBDE 1 and was hoping someone could help me with this question, I searched all my notes, wiki, books and couldn't figure it, it seems fairly easy but i just can't get the connection:

which of the following represents the correct size and caracteristics of the nerve fibers that conduct sensory input of pain from the oral-facial region?

a. large diameter myelinated
b. small diameter myelinated
c. large diameter unmyelinated
d. small diameter unmyelinated

answer is d

are they talking about the Adelta and C fibers? if so, I know that Adelta are myelinated and C fibers are unmyelinated, so why are they calling both unmylinated??? and A fibers are large diameter while C are small diameter but both are used for pain so how do you know which one are they talking about???please help , thanks in advance
