NCT06578832

Brief Summary

The aim of this study is to compare the oral health findings, salivary parameters and disease-related quality of life of children with different stages of Chronic Kidney Disease(CKD), those undergoing dialysis and transplantation, with healthy children, and to evaluate certain serum biomarkers in children with CKD.

Outcome Measures

Primary Outcomes (3)

  • Oral Health Status

    DMFT/dft indices, DI (Debris Index), CI (Calculus Index), and OHI-S (Simplified Oral Hygiene Index) scores,DDE Index (Developmental Defect of Enamel), MGI Index (Modified Gingival Index) and ICDAS-II. DMFT/dft index values, DI, CI, and OHI-S scores as numerical values. DDE, MGI Index and ICDAS-II are percentage of participants with these conditions. Prevalence of limited opacities, caries and gingival inflammation based on DDE, ICDAS II and MGI indices.

    baseline

  • Salivary Analysis

    Salivary urea, calcium (Ca), potassium (K), phosphorus (P), total oxidant status (TOS) levels, and salivary flow rate. Concentration of urea, Ca, K, P, TOS in mg/dL or equivalent, and salivary flow rate in mL/min.

    baseline

  • Quality of Life (QoL)

    Quality of life scores on the KINDLR scale for both children with CKD and their parents

    baseline

Secondary Outcomes (3)

  • Correlation Between Oral Health Indices and Salivary Biomarkers

    baseline

  • Correlation Between Salivary Urea and Serum Urea Levels

    baseline

  • Correlation Between Salivary and Serum Calcium and Phosphorus Levels:

Oral FindingsDIAGNOSTIC_TEST

DMFT/dft Index: Measures decayed, missing, and filled teeth. ICDAS II: International Caries Detection and Assessment System, used for detecting and assessing dental caries. DDE Index: Developmental Defects of Enamel index. BAKH Index: Basic Anatomic Keratinization Hierarchy, typically used in specific studies. DI (Debris Index): Assesses oral hygiene based on the amount of debris on the teeth. CI (Calculus Index): Measures the amount of calculus (tartar) on the teeth. OHI-S (Simplified Oral Hygiene Index): Assesses oral hygiene based on the presence of debris and calculus. MGI (Modified Gingival Index): Assesses the severity of gingivitis based on inflammation.
