This video of Zinc phosphate cement, a Dental Cement topic from Dental Materials is from Aspire32 and made by Dr Suresh Shenvi. Zinc Phosphate cement is one of the oldest cement from all the dental luting cement and is commonly used for luting permanent metal restorations and as a base even today. It is a high-strength cement base, mixed from zinc oxide powder and phosphoric acid liquid. Since it’s a standard cement to compare, with many dental entrance exams do ask questions from this topic of Dental Materials. This video covers Zinc Phosphate Introduction, Properties, Applications, Advantages, Disadvantages. Easy dentistry at Aspire32 helps grasp such topics of Dentistry in the simplest possible way for dental students and dentists. This zinc phosphate cement also explains the uses of zinc phosphate cement.
This video of Aspire 32 is made by Dr. Suresh Shenvi who has cleared various exams like ADAT, NBDE from the USA, DHA from Dubai, and various Indian Entrance exams like PGI, KCET, NEET. I am MDS in Conservative Dentistry and Endodontics by profession. I am also an author of dental books on the entrance exam and I am also currently a faculty at KLE University and a receiver or best teacher award.

Thank you so much sir ,this is a very helpful video it's much easy to understand especially the importance of alumina in zinc phosphate

@Aspire32 4 года назад

I agree.. as a student even I thought its only phosphoric acid which matters a lot. Hope you will share this video with others :)

@degfh2009 Год назад

Great to hear from you sir.... Thanks

@Aspire32 Год назад

most welcome

@riddhikakodkar2055 4 года назад

Sir, for the Q ; the best cement that can be used it GIC ( fluoride release, elastic modulus close to dentin & the pH is not acidic). However zinc polycarboxylate can also be used. ( lager molecular wt. & the pH increases in 24h)

@Aspire32 4 года назад

Great answer..but you should first think about the type of restoration :)

@mrunalibhimte2992 3 года назад

best you tube channel for budding dentist like us...🙂

@Aspire32 3 года назад

Thank you so much for the appreciation :):)

@Medico_fitness_freak Год назад

When the thickness of dentine is more than 1.5 mm ,, it’s okay to use zinc phosphate bcx it will not elicit any pulp sensitivity . On the other hand it’s a good insulator as compared to GIC and zinc polycarboxylate cements

@kamblemanasi2310 4 года назад

Thank you Sir!! Liked it as always:)

@Aspire32 4 года назад

Thank you too.. For being a regular viewer of my Channel :)

Sir please make a video over topic : Factors affecting setting and mixing time of zinc phosphate cement

@pankhurikumawatshenvi9858 4 года назад

Very informative video. Thank you.

@Aspire32 4 года назад

So nice of you :)

@servantsofprophetmuhammads2538 Год назад

Sir I have pulp exposed in molar lower jaw, but Dr put me zn phosphate filling , is it better, and can I do other fillings in future 8b this area

@drajaypraveen 4 года назад

Nice sir... neatly explained....

@Aspire32 4 года назад

Than you Dr Ajay : ) Thank you soo much for the continues support :)

@lisamariecolaco793 4 года назад

Sir for the quiz question - although zinc Polcarboxylate cement can be used at RDT 1.5mm, GIC would be the best option due to its - chemical bonding, high fluoride release, anticariogenic property, elastic modulus very similar to that of dentin, its pH is much more suitable than that of zinc phosphate and slightly better than zinc Polcarboxylate so no worries of any irritation to the pulp

@Aspire32 4 года назад

Great answer..but you should first think about the type of restoration before deciding base:)

Is it possible to increase free acid value of zinc phosphate without increasing the total acid value?

@sanjaikumar7914 2 года назад

Thank you so much sir

@Aspire32 2 года назад

Most welcome :)

@jayantipatil969 Год назад

Sir explain comprssive and tensile strength.

@zrational7882 8 месяцев назад

Zinc phosphate for amalgalm bc it has better insulating property and GIC for composite

@zeeshashahan1348 3 года назад

Sir should we remember the percentages of the composition of powder and liquid as well as the properties for exam

@Aspire32 3 года назад

In theory exam the teacher do expect this information. In entrance exam they dont ask about the percentage unless there is a very important point associated with it. For exam the gutta percha has maximum zinc oxide in ints composition even though the name days gutta percha

@jesjo2097 3 года назад

very helpful lectures sir, i wish i could learn like this during my ug class

@Aspire32 3 года назад

Thanks for that beautiful comment :) you can watch many topics of dental Materials and learn it Simplified way . Here is the link ru-vid.com/group/PLdPsg6P-6VldkI_N1LglBPGc114Ksq9Ir

@anuhyaepuri6872 2 года назад

Sir may I know that whether there is any lecture on biocompatibility of dental materials chapter

@Aspire32 2 года назад

Not made that yet. But do visit the playlist section to find all the other topics :)

@helllokity98 2 года назад

Sir can we write zincoxide +phosphoric acid ->zinc aluminophosphate for setting reaction in theory exam

@Aspire32 2 года назад

Its better to write it as mention in the video since composition section has more marks

@simranjeetkaurdeol670 4 года назад

Thank you sir .

@Aspire32 4 года назад

Most welcome :) Do take part in the quiz question :)

@kamblemanasi2310 4 года назад

Sir, to make an attempt to the quiz.. i feel GIC can be used as a base for 1.5mm of RDT as its ph is not as bad as other cements, also its similar elastic modulus like dentin, releases more of fluoride.

@simranjeetkaurdeol670 4 года назад

Zinc Polycarboxylate ...as pulpal response is less ....after 24hr ph is 5-6 , ...polyacrylic acid has less penetration into the dentinal tubules... Not as good as gic but it has also got fluoride release . .... chemical bonding .

@Aspire32 4 года назад

Good reasoning.. but you should first decide it based on the type of restoration.

@pearlsoul657 3 года назад

Sir ...which is the best luting agent among Zn phoshate, Zn polycarboxylate and GIC???

@Aspire32 3 года назад

Resin cement which is not mentioned in your question. Thats the best for Luting

@pearlsoul657 3 года назад

@@Aspire32 Thank you

@kf-ot6vw 3 года назад

@@Aspire32 sir would u plz make a video on resin cements as to why they are better than the others.... Is it bcz they are insoluble? But wouldn't resin cements have polymerization shrinkage giving rise to microleakage?

@Aspire32 3 года назад

@@kf-ot6vw Yes. It does shrink but since the amount of material is very less, the shrinkage is clinically insignificant

@avisagoo3755 3 года назад

Thank you for your video sir . And for your question- we will use gic if 1.5 mm dentine depth is remaining .. because gic is not a pulp irritant . As compare to zinc phosphate it’s ph is low which cause pulp irritation .

@Aspire32 3 года назад

Great. But the anser can be both polycarboxylate and gic because if you just consider pg then polycarboxylate is better. But GIC has other. Benefits like chemical bonding. Hence gic is preferred. The best luting cement js Resin cement :)

@Muhammad-Sajid-2003 Год назад

Sir I know this is not a video of calcium hydroxide but I have question about it, that is how much ether required for dissolution of calcium hydroxide?

@Aspire32 Год назад

I did not get you. May I know why this question is important?
