Question - What function is performed by the nerve in a tooth? —Preceding unsigned comment added by 69.251.237.186 (talk • contribs)

• Probably tooth and has more to say about that, but one function that springs to mind is the sense of touch. Zocky | picture popups 03:01, 20 January 2006 (UTC)
• There are five functions of the pulp of the tooth (which is what I'm interpreting to be when you refer to "nerve"), and I don't know if this is in the tooth article or the Pulp (tooth) article (but it should be). (1) Induction - the formation of dentin is initiated by the pulp. (2) Formation - the odontoblasts which form dentin are found in the pulp and form dentin initially and later in life in response to injury. (3) Nutrition - nutrients essential for dentin formation is provided by the pulp. (4) Defense - foreign substances are identified by the pulp and brings an immune response via the blood supply. (5) Sensation - neural sensation are transmitted from the tooth to the nerves and interpreted as sharp or dull pain. - Dozenist talk 03:38, 20 January 2006 (UTC)

Wow

I've rarely seen such a detailed article on such a specific medical topic in Wikipedia. Excellent job, contributors. Deco 02:57, 20 January 2006 (UTC)

A question

I agree: this is an excellent article. I thought I read somewhere that someone is doing research with stem cells with animals to create new teeth by implanting the cells into the gums. Any credence to this? Masa 21:43, 20 January 2006 (UTC)

I am not completely knowledgable about the specifics, but I have heard that there is that research using animal stem cells and attempting to create teeth with it. Last I heard, research is still in progress and only being done in animals currently. The hope is in the future people missing teeth will have the option of of replacing the tooth with a real tooth, instead of the current options of fixed/removable prostheses and/or implants. -Dozenist talk 01:25, 21 January 2006 (UTC)

The node 66 does not function.--59.113.107.54 14:21, 22 April 2006 (UTC)

that would probably be this article -> Nakao, K. Morita, R. Saji, Y. Ishida, K. Tomita, Y. Ogawa, M. Saitoh, M. Tomooka, Y. Tsuji, T. (2007). The development of a bioengineered organ germ method. Nat Methods 4, 227–230.´

They dissociated epithelium and mesenchyme from murine cap stage tooth germs to single cells and reaggregated them in vitro and grew them in vitro for a short time to allow early morphogenesis. Then they implanted these explants to the jaw of the mouse, where they developed into a rather normal tooth. See for instance this paragraph in one of my articles for more: http://www.stembook.org/node/551#sec1-7 Tummers (talk) 09:08, 17 February 2010 (UTC)

Comment

This article may be detailed but it lacks many links which makes it difficult for a non-medical person to read.

Indeed, I have no idea why it was a featured article. It's so technical, so full of jargon, that it's virtually unintelligible, IMO. RobertM525 (talk) 09:06, 16 June 2008 (UTC)

Merge with Odontogenesis?

I think we should merge Odontogenesis and Tooth development. Tooth development is the more complete article with references, Odontogenesis should probably be re-directed to Tooth development (it is the more technically accurate term). Odontogenesis appears to basically be summary of parts of:

Barbara Young, Paul R. Wheater (2006). Wheaters Functional Histology. Elsevier Health Sciences. p. 255. ISBN 9780443068508. http://books.google.com/books?id=88tla60sHAUC&pg=PA255&lpg=PA255. 

Which I have added as a reference to this article (see Bud stage section). I think we could just fill in Tooth development with more info from this reference and this would be good. --InsufficientData (talk) 18:39, 30 December 2008 (UTC)

Big sections with single references

This article has large sections refed by a single reference. It's not clear if the whole, big section is from the single reference at the end, whether it is copy vio or what. Loopy48 (talk) 00:47, 29 December 2010 (UTC)

Work needed
