Thank you so much. It was so helpful. I'm in grade 3 in dentistry and a doctor of mine asked me some questions to bring back him the answers, so i got almost all the answers except this one😁may u reply me, thank you again👏 Why light cure composites stops curing more even the light is applied? What makes the limit of curing?!

Amazing! Thank you so much these videos are saving me from reading pictureless textbooks

I'm not preparing for the exam but I'v been looking for these information for so long, thank you so much Dr. Ryan!

dude i'm a recent graduate and legit you summarized an extremely important topic in 30 minutes respect and keep up the good work 👌👌

Thank you for this!! pls keep uploading videos like these for the NBDE!! very helpful in my studies especially in this time of quarantine.

Dr. Ryan, thank you so much for your concise efforts and detailed info. I am a veterinary dentistry resident getting ready for board examination and your foundations are priceless as we do not learn in an academic institution for most of us- we are mostly self taught for theory but use most of the same human text books with slight species variations. Thank you!!!

Thank you Dr Ryan for all your efforts. I found during community service that I used these materials over the years and you make me stop and think about the importance of the development of these materials. For example I used Ketac silver or Cermet- ionomer as restortaive material and I found it was part of an effort to improve the filler of Glass Ionomer restortaion by adding metal alloy to improve the filler part and reinforce( first approach). Then the second approach was to improve the matrix not the filler by adding Di-methyacrylate monomer which you described in other series to have covalent crosslinking of the matrix through free radical by creating carbon- carbon bond in addition to primary ionic bond in GIC which is excellent in order to reduce the secondary bonds that is causing poor mechanical properties such as weakness, law modulus of elasticity, and law fracture toughness. I found also that the ionic bonds through acid -base reaction leads to release of calcium, aluminium,sodium,fluoride and silicate ions which is favorable for caries control.Thank you very much. Dr K. Etheridge MPH-d.

Thank you for the great videos. about the C-factor slide, I think the class V has similar c-factor as class I, it should be class VI that has a c-factor of 1:5.

Thank you so much for this series. Have you made a video about gold restorations though? I haven't found anything on the channel for that

I have a video on metal alloys in my Prosthodontics series, but not much on the technical aspects of gold restorations since they are not tested routinely on the board exam. That is a great idea for a future video though!

how is the lower wear resistance of flowable a good thing? dont we want a high wear resistance?

How would a Class V restoration have such a low C-factor? Wouldn't a traditional class V have the same C-factor as a Class I restoration?

Nice video.. please make a video on matrices and wedges

Hello quick question, in the class 2 cavity preparation Video you the cavity has 6 walls 4 external and two internal , bur here when explaining the C factor figure you said the number of walls is 4 that’s why C factor is 2 cause it’s 4/2 but why i m thinking that the number of bonded walls should be more cause there is an axial and gingival wall ?? Can you please explain that more Dr, that I you

Doctor, if the patient is 12 year old and uncooperative, what restoration material will u give? State why? Thank you v much

hello Dr Ryan, i have a question regarding composite types and your categorization in the operative INDBE video #6 to summaries what i understood is that larger filler particles causes the matrix of the composite to wear off faster making the composite rougher and higher filler content causes less water absorption and shrinkage however you ended the slide by saying that in case of flowable composite the good thing is that it has lower wear resistance, wouldnt that be a disadvantage ?, and since it has lower wear resistance wouldnt it then have large particles and high content of filler since we stated that too little matrix is what causes the wear and exposes rough composite i assumed that low filler content and size would mean weaker composite that wears off more and high filler conc. is what would prevent it wearing for example the macrofill would be strongest with the highest wear resistance and flowable the opposite a paper i read as well suggests that the higher the filler content of a composite the more wear resistance it has. thank you for your time

hey ryan i m interested in becoming your super patron and i m curious about how frequent you can give one on one attention or time to solve my queries.

I'm a little confused by the C factor of Class V lesions. Wouldn't a classic preparation yield a C-factor of 5?

good day Dr. Ryan, I am grateful to your videos. they have gotten me through my BDS program with ease. would your videos help me tackle the British ORE? or is it specifically confined to the INBDE. I really wanna know as I would like to continue studying using mental dental.

do you mean lower the C-Factor, more the microleakage since Class V has 0.2 CF and it has greater microleakage?

@mentaldental

Theoretically, according to the overall trend, the more surfaces that are bonded to the higher risk composite will “peel” away from one of those surfaces as it undergoes polymerization shrinkage. Class V has the lowest amount of walls bonded to (theoretically, but not always practically).

Is the resin tag composed of only primer? Or is it a mix of the primer and adhesive?

@mentaldental

3 жыл бұрын

Hard to say exactly, because it depends on the bonding system you use. It’ll be mostly primer if you’re using a separate primer, but otherwise it’ll be a mix of the two.

So the best composite type is (nanohybrid) ? And thank you for all of your videos they are really and truly helpful and without them I would’ve been lost in the dentistry world 😅

Hello dr please I HAVE A QUESTION in regards to the C factor for the cl v , is it should be 5/1 just like class one ? as we have all the walls, I LOOKED IN TO sources and some says its this ratio and some says its the reverse this is important as its gonna be bad prognosis for it just like class 1 for the shrinkage, meanwhile if its the reverse its gonna have excellent prognosis with minimal shrinkage

@mentaldental

Hello, there are several other comments that have already asked this question... not sure if you saw them. It really comes down to how exactly the tooth was prepared for a Class V restoration. Some resources will consider the entire dish-shaped prep as one surface only, which explains having only one bound surface. Other resources, consider each wall separately for a 5:1 ratio. I would stick with the 1:5 ratio, personally.

BNC bonding agent

Can glass ionomer cement be used when there's a deep carious lesion and you left behind affected dentine. Affect dentine even through it's hard doesnt bond well with resin composite, can you place glass ionomer filling and then place composite after a few months?

@mentaldental

3 жыл бұрын

You are absolutely correct that caries-affected dentin negatively influences bond strength. You can definitely do what you are suggesting, although sometimes the area of affected dentin will not be large enough to impact bond strength and subsequent leakage at the periphery of the restoration where the bond is perhaps most important.

B and c bonding agent

Hello to my favourite KZreadr!! I am a little confused Dr. Ryan, Class V has 5 bound surfaces, therefore the ratio of the bound to unbound surfaces remains the same as the Class I, 5:1. I imagined a box, Class I is a box with a missing roof and so is a Class V but a differently shaped box with not so high walls (but there is walls). Please correct if I'm wrong!

Thank you so much doctor Ryan, I’m not taking the exam but the short, high yield video form is really good to understand major concepts then build upon further knowledge in the future. I’m in third year right now so besides this great channel what do you recommend for people who don’t want to take the exam but rather be good dentists and build good foundations while in dental school, a more clinical and practical further readings in the same short high yield format, any to the point -preferably all in one- review textbooks/handbooks/flashcards to know techniques and tricks?
