Molecular study of Streptococcus mutants Associated with Interlukine-8 Among pulpitis patients

Abstract

Abstract Background : Bacterial antigens that permeate into the pulp through dentinal tubules seem to be the cause of acute pulpal inflammation under caries. This led to the hypothesis that, in the pulp, where B cells and plasma cells predominate as a control, cytokines elicited by antigens from Streptococcus mutans, which frequently dominates shallow lesions, could play a significant role in eliciting the initial T-cell response. Furthermore, the pulp's cytokine content was S. mutans produced strong numerous inflammatory cytokines, according to ELISA analysis.   Peripheral blood mononuclear interleukin-8 responses were detected in human dental plup Objectives:

    The purpose of this research was to detection of Streptococcus mtanus  linked to pulpitis  by molecular methods. Estimation the Interlukines-8 by ELISA Among the patients.

 Materials and Methods: A total of 80 samples (50 cases; and 30 healthy), 17 males and 33 females, aged (16–36) years. During the acute stage of pulpitis , samples are collected to isolation by the sterile paper point (size 3) is inserted in  inserted at the lowest locations of the pulpitis infection then the paper point is put in an Eppendorf tube and stored at deep freeze until it was used for real-time PCR technique.

 Results: The most common bacteria detected in real-time-PCR is Streptococcus mutants, Our results in pulpitis show that the percentage of gram- positive bacteria Streptococcus mutans is 64% in patients , The interlhkine-8 is (145.6646 pg/ml) Among Patients was find High significant compared to the controls.

Conclusion: S.mutanus detection was found to be remarkably high compared to that of controls. Distribution of infection according to gender is (66%) female and (34%) male and the number of Patients with Pulpitis  at patients is significantly higher than in control  groups.
