    Yes


  • Do the results support the claims? If not, what other evidence is required?

    Yes


  • If a protocol is provided, for example for a randomized controlled trial, are there any important deviations from it? If so, have the authors explained adequately why the deviations occurred?

    No


  • Is the methodology valid? Does the paper offer enough details of its methodology that its experiments or its analyses could be reproduced?

    Yes


  • Would any other experiments or additional information improve the paper? How much better would the paper be if this extra work was done, and how difficult would such work be to do, or to provide?

    No


  • Is this paper outstanding in its discipline? (For example, would you like to see this work presented in a seminar at your hospital or university? Do you feel these results need to be incorporated in your next general lecture on the subject?) If yes, what makes it outstanding? If not, why not?

    Yes- it would be great lecture for a group of oral pathologists.


  • Other Comments:

    Necrotizing sialometaplasia is a benign and self-limiting lesion of the salivary glands.  A case report of a 16 year old Indian female is presented in detail.  The authors provide the reader with the caution to be aware of a potential diagnostic pitfall when attempting to diagnose this lesion.  A nice list of references is also provided.

    The authors also state that necrotizing sialometaplasia does not usually recur.  If a patient's lesion does not resolve a repeat biopsy is indicated.  The differential diagnosis includes mucoepidermoid carcinoma and squamous cell carcinoma.

  • What are the main claims of the paper and how important are they?

    To present a case of Necrotizing Sialometaplasia.


  • Are these claims novel? If not, please specify papers that weaken the claims to the originality of this one.

    There are numerus reported cases on this disease


  • Are the claims properly placed in the context of the previous literature?

    Yes


  • Do the results support the claims? If not, what other evidence is required?

    No. There are no adequate microscopic support.


  • If a protocol is provided, for example for a randomized controlled trial, are there any important deviations from it? If so, have the authors explained adequately why the deviations occurred?

    Not apply.


  • Is the methodology valid? Does the paper offer enough details of its methodology that its experiments or its analyses could be reproduced?

    No.


  • Other Comments:

    Unfortunately, this case is not properly presented, since clinical data and microscopic images do not support the diagnosis of Necrotizing Sialometaplasia. The correct diagnosis is a traumstic ulcer. It is clear that this lesion is related to the injection of an anesthetic to the palate. Microscopic images do not present the histopathologic findings of Necrotizing Sialometaplasia. They are consisten with necrotic tissue related to anesthetic injection.

    This article shows a necrotizing sialometaplasia affecting the hard palate, following locan aneshesia.
    This article is well written and it analyzes the possible complications after a local anesthesia, however, the  necrotizing sialometaplasia is a  well known disease and the hard palate is a place of choice for its manifestation. The submandibular swelling has to evaluate with a differential diagnosis. and it's not so easy to arrive to a demolitive surgery only for this aspecific manifestation.

  • Other Comments:

    Case history, especially past dental history and History of present illness has not been documented well

    Conventional imaging using a maxillary occlusal view would have been sufficient when clinically a benign lesion was suspected

    Clinical photographs not shown

    Indication for a CT Scan ???

    Differential diagnosis completely ignored

    History and clinical examination indicates more in terms of malignancy, which has been ignored

    Discussion is a total mess

    English grammar and writing style is not good.

  • Other Comments:

    •Regarding differential diagnosis, authors suggested necrotizing sialometaplasis and other infective lesion, while malignancy has been ignored. At the same time, authors mentioned that "Correct clinical diagnosis of necrotizing sialometaplasia is important because this lesion mimics the appearance of malignant disease, both clinically and microscopically"!
    •What was the indication for computed tomography and the significance of neoplastic changes in the biopsy while ignoring malignancy in the differential diagnosis!
    •In the discussion, the authors reported that "In an experimental study in a rat model, local anesthetic injections induced necrotizing sialometaplasia". Authors had not mentioned if the used anesthetic injections were expired as they suggested in the etiology of the present case?
    •Authors did not discus in detail how to differentiate histopathologically between squamous metaplasia of ducts and reactive fibrosis in late lesions in one hand and the two most important malignant lesions squamous cell carcinoma and mucoepidermoid carcinoma in the other hand.
    •I think that, one of the main diagnostic keys in this case is the case history which was completely ignored in the discussion.
    •My conclusion that, I have a negative decision about this article.
