Query in Restorative Dentristry

[Guest guest]

Hi All, I have two doubts regarding Restorative Dentistry: Posterior resin

composites are best avoided in restoration with deep gingival extensions, although a bonded base approach can be adopted. Could anyone please tell me what is bonded base approach here? Another question is regarding Class V cavity in Pink Book (4th Edition) In one place it is said that "Amalgam should be avoided in Cervical Cavities due to LICHENOID reaction", but in another place it is mentioned that "Spheroidal amalgams are preferable for large class V". Don't you think this contradicts? Can anybody please through some lights on this? Thanks in advance.Regards,Naseema Iqbal

it says LARGE CLASS V, where isolation can be a problem for composites, by

lichenoid reaction, do u think that either pulp is affected or the associated

discoloration? if u think pulp is affected then zinc phosphate lining is advised

before amalgam is condensed into the cavity

offcourse amalgam should be avoided coz of lichenoid reaction but under amalgam it only says if u have to choose between amalgams only i,e among lathe cut and spheroidal amalgams , spheriodal amalgam is preferred . Its not written like between composite and spheroidal amalgam u should choose spheroidal. they are not comparing between composite and amalgams here. hope it helps..regardsdivi From:

Hi , Thanks a lot.what about the first question?Posterior resin composites are best avoided in restoration with deep gingival extensions, although a bonded base approach can be adopted. Could u please tell me what is bonded base

approach here? From: Enigma <wiseguy944@...> Sent: Tuesday, 27 December 2011 12:29 PM Subject: Re: Query in Restorative Dentristry

hello Iqbal,

It is a reinforced restorative glass-ionomer cement used with a composite resin

restoration. the glass ionomer is used as a base.

- I would also choose spheroidal but if there is an option of spheroidal +lathe-cut then that is the best choice as spheroidal is more fluid, easier to condense, can be carved immediately and takes only 3hrs to reach occlusial strength. LATHE-CUT takes 6hrs. Its also mentioned that spheroidal r preferable for 'pinned restoration' Ref- PBSent from my BlackBerry wireless device from MTNFrom: Divi Divi <divi_ore@...>Sender: Date: Tue, 27 Dec 2011 20:16:19 +0530 (IST) < >Reply Subject: Re: Re: Query in Restorative Dentristry offcourse amalgam should be avoided coz of lichenoid reaction but under amalgam it only says if u have to choose between amalgams only i,e among lathe cut and spheroidal amalgams , spheriodal amalgam is preferred .
