Evaluation of Free Aminoacids in Saliva as A Diagnostic Biomarker of Periodontal Disease

Amino acids (AAs) are organic molecules that are associated with inflammation and innate immunity diseases with critical roles in the cell repair and protection process. Our aim was to identify the free amino acids in saliva of a group of periodontitis patients and healthy individuals and additionally to assess their levels in different periodontal disease types and compare it to the healthy individuals.

About this study

The study consisted of three groups: healthy individuals (control(C); n=20), Stage III Grade B generalized periodontitis (GP-B; n=20), and Stage III Grade C generalized periodontitis (GP-C; n=20). Clinical periodontal parameters (plaque index (PI), gingival index (GI), probing depth (PPD), gingival recession (GR), clinical attachment level (CAL) and bleeding on probing (BOP)) were measured. The amino acid analysis in saliva was accomplished by liquid chromatography-mass spectrometry (LC MS/MS) as mean concentration.

Treatment and study plan

Saliva collection of patients and salivary free amino acids analysis

Other

Other names: Salivary free amino acids in patients with periodontitis

Primary outcomes

  1. Pocket probing depth

    Time frame: 2 years

    Measurement of the depth of a sulcus or periodontal pocket determined by measuring distance from a gingival margin to the base of the sulcus or pocket with a calibrated periodontal probe.

  2. Clinical attachment level

    Time frame: 2 years

    Clinical attachment level (or loss, CAL) is a more accurate indicator of the periodontal support around a tooth than probing depth alone. CAL is measured from a fixed point on the tooth that does not change, the CEJ.

    To calculate CAL, two measurements are needed: distance from the gingival margin to the CEJ and probing depth.

    In recession: probing depth (+) gingival margin to the CEJ (add). In tissue overgrowth: probing depth (-) gingival margin to the CEJ (subtract)

  3. Bleeding on probing

    Time frame: 2 years

    referring to bleeding that is induced by gentle manipulation of the tissue at the depth of the gingival sulcus, or interface between the gingiva and a tooth.

Secondary outcomes

  1. Amino acid Analysis

    Time frame: 2 years

    The AA analysis of the saliva was performed by LC-MS/MS by using the Thermo Scientific TSQ Quantum Access MAX (Thermo Scientific, Schaumburg, IL, USA) according to a modified version of Le et al.'s method.
