Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The present investigation was conducted on 100 individuals allocated into four groups; 25 healthy controls, 25 patients having OPMDs with dysplasia; 25 patients having OPMDs without dysplasia, and 25 oral cancer patients. Demographic data including data related to different risk factors, modified gingival index, oral hygiene level, in addition to salivary levels of IL-6, IL-8 and sCD44 were assessed.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Histopathologic evaluation:

Biopsy samples were obtained from all lesions to verify the diagnosis and establish the presence of dysplasia in the potentially premalignant lesions before allocating patients to their specific groups.

History and clinical assessment:

Demographic data as age and gender, medical history and habits as smoking and alcohol were obtained during patient interview. Modified gingival index (MGI), level of oral hygiene (OH) and the number of remaining natural teeth were also assessed. Subjects not willing to sign a written informed consent, pregnant females, lactating mothers, and patients with immunosuppressive disorders were excluded.

Modified gingival index (MGI) evaluates the presence and degree of gingival inflammation. A score of 0 means absence of inflammation. 1 indicates mild inflammation (slight redness) of any part of the gingiva. 2- mild inflammation of the whole gingiva. 3- moderate inflammation (moderate redness, edema, and/or hypertrophy) of the gingiva. 4-severe inflammation (marked redness and spontaneous bleeding) of the gingiva. Level of OH care was evaluated corresponding to the OH habits of the patient and efficiency of plaque removal. OH, level is scored as: 1- very good, 2- good, 3- fair, and 4- poor OH.

Collection of 1.0-2.0 mL of whole unstimulated saliva was obtained between nine and twelve in the morning, to evade diurnal alteration. Participants refrained from eating, smoking, brushing, and mouthwash use, 2 hours before to salivary sampling, which were stored at -70 ◦C till analyzed.
