Is any code to prevent duplicate meta description on blog pages

I use rell canonical on blog page and to prevent duplicate title y use on page category title de code %%page%%

Is there any similar code so to description?

Well, I checked the site and you are already adding the page number to the title. Then do the same for the Categories / or any other area that is being "paged".

bloh/page/2/

title: Blog dental de Clinicas Dentales Propdental - Página 2 de 59
desc: Lee sobre cierto tema y aprende bla bla bla - Pagina 2

In my case I would remove the "de 59" just to avoid the 70 chars limit in titles.

You can get great info here: http://moz.com/learn/seo/title-tag and here: http://moz.com/learn/seo/meta-description

Hope that helps.

I am using wordpress and YOAST seo plugin.

I have specific metas for each posts, the duplicate meta descriptions are on different blog pages. Maybe it should be like that

http://www.propdental.es/blog/

http://www.propdental.es/blog/page/2/

http://www.propdental.es/blog/page/3/

same or no description on page 2, and different title due to place this code on title  of blog page %%page%%

It would help if you tell us a little more about the platform you are using. If it is wordpress, you should go with the Yoast SEO plugin, which will make all the changes and adjustments for you, while you can set specific METAs for specific posts.
