Why perform a literature review?

I read with great interest the cover article entitled “Photographic and videographic assessment of the smile: objective and subjective evaluations of posed and spontaneous smiles” by Walder et al, published in the December issue (Walder JF, Freeman K, Lipp MJ, Nicolay OF, Cisneros GJ. Am J Orthod Dentofacial Orthop 2013;144:793-801).

Early on in my first read of the article, I was dumbfounded by the statement in the introduction that “the dental literature is surprisingly lacking in its discussion of the dynamic nature of the smile as it relates to the methods used to elicit, record, and reproduce it and how it reflects our patients’ esthetics.”

The following articles address this topic.

I hope that this deficiency in scholarship by the authors will instruct others how to more thoroughly review the literature on any particular topic.
