A Comparative Elemental and Surface Analysis of Root Cementum in Severe Periodontitis and Healthy Teeth

Year: 2025

Type: article

Abstract: This study aims to compare the elemental composition and surface characteristics of root cementum in teeth affected by severe periodontitis with those of healthy teeth.Forty-seven teeth, including 25 teeth affected by stage III, grade C periodontitis and 22 healthy teeth, were extracted from patients aged 17 to 34 years. The cementum surfaces were analyzed using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) to evaluate surface morphology and elemental composition.SEM images revealed that healthy teeth exhibited a homogenous, smooth cementum surface, while teeth affected by periodontitis showed an irregular, uneven surface with deep crack lines and resorption areas. EDX analysis indicated significant differences in elemental composition; periodontitis-affected teeth had lower calcium and phosphorus but higher magnesium, sodium, and sulfur levels than healthy teeth.Periodontitis significantly alters the surface characteristics and elemental composition of root cementum, which may contribute to disease progression and impaired periodontal health.
