Cementogenesis in Patients with Localized Aggressive Periodontitis

Abstract

Objectives: The aim of this study was to determine the cementum thickness in the first molars of patients with localized aggressive periodontitis (LAP) compared to healthy individuals. Materials and Methods: This case-control study compared eight first molar teeth af-fected by LAP with eight third molar teeth of healthy individuals. The teeth were dis- infected by immersion in 10% buffered formalin solution for three days and were then sectioned. External mesial root surfaces (middle one-third) were evaluated under a ste- reomicroscope by a blinded pathologist to determine the mean thickness of cementum. SPSS software (version 16.0) and t-test were used for statistical analysis. Results: Histological examination revealed a significant difference between the two groups in terms of the amount of cementogenesis (P<0.001) .The thickness of cemen- tum was higher in the control group (105.16±11.5 μm) than in LAP patients (86.44±7.3 μm). Conclusion: This study demonstrated the presence of cementum hypoplasia in mesial root surfaces of first molars affected by LAP.
