NCT06764043

Brief Summary

Background: To investigate the effect of molar incisor hypomineralization (MIH) on periodontal health, to evaluate the relationship between gingival crevicular fluid (GCF) volume, and GCF biomarkers such as matrix metalloproteinase-8 (MMP-8), matrix metalloproteinase-20 (MMP-20), and transforming growth factor-beta 1 (TGF-β1), and MIH. Methods: The study was conducted on 40 pediatric patients diagnosed with MIH (Study Group/SG), and 40 pediatric patients healthy for MIH (Control Group/CG). Clinical periodontal measurements (plaque index (PI), gingival index (GI), probing pocket depth (PPD), and GCF volume were performed. Concentrations of MMP-8, MMP-20, and TGF-β1 in GCF were determined using enzyme-linked immunosorbent assay (ELISA). Mann-Whitney U test and T-test were used for comparisons between groups. Significance was set at p=0.05 for statistical analysis.

Outcome Measures

Primary Outcomes (3)

  • Periodontal indexes measurement

    PI, GI, and PPD measurements were performed to evaluate the periodontal health of the children participating in the study.

    1 day

  • GCF measurement

    In the study, GCF was collected in the morning hours (between 09:00 and 11:00) one day after the patient's clinical periodontal measurements were complete.

    1 day

  • Evaluation of MMP-8, MMP-20 and TGF-β1 Levels by ELISA Method

    The levels of MMP-8 (Elabscience® EL-H1450, Biotechnology Co., Ltd, Wuhan, China), MMP-20 (Bioassay Technology Laboratory, Cat. No E4139Hu), and TGF-β1 (Elabscience® EL-H0110, Biotechnology Co., Ltd, Wuhan, China) in GCF samples were measured using ELISA kits.

    for three days from the beginning of the study

Interventions

In this study, it was aimed to measure the levels of MMP-8, MMP-20, and TGF-β1 in GCF together with the volume of GCF to investigate the effect of MIH on oral hygiene, and gingival health, and also to evaluate the relationship between MIH, and various biomarkers.
