Comment on “Xerostomia and Salivary Gland Hypofunction in Patients with Oral Lichen Planus Before and After Treatment with Topical Corticosteroids”

The recently published research article “Xerostomia and Salivary Gland Hypofunction in Patients with Oral Lichen Planus Before and After Treatment with Topical Corticosteroids” by Hala Al-Janaby, et al. [1] was studied with great interest. The article concluded that treatment with topical corticosteroids in patients with oral lichen planus could result in improving the symptoms of xerostomia. The treatment, however, is not statistically associated with differences in stimulated and unstimulated salivary flow rate, unstimulated salivary pH or buffering capacity. Since the two conditions (xerostomia and salivary gland hypofunction: which these terms are not equal, Xerostomia: the subjective complaint of dry mouth. Salivary gland dysfunction: objective evidence of alterations (qualitative and/or quantitative) in saliva output. Dysfunction may include a decrease (hypofunction) or an increase (hyperfunction) of the saliva output (Mahvash Navazesh 2017) are commonly observed in patients with oral lichen planus [1], the results of the above study could significantly impact the management and treatment of those patients.With respect to the results presented in the article, the followings are of concern
