| Introduction: One-stage oral disinfection technique has been
developed to prevent cross-contamination between the treated
and untreated areas between treatment sessions. Considering
the role of inflammatory mediators in periodontitis, this study
has been designed to compare the effects of one-stage oral
disinfection with quadrant scaling and root planing (Q-SRP) on
serum interleukin-27 (IL-27) levels in patients with moderateto-
advanced periodontitis.
Materials and methods: In this study, two groups were considered.
One group was treated with one-stage full-mouth oral
disinfection (FMD), while the other group was treated with
Q-SRP. In each group, 20 patients with chronic periodontitis
were randomly selected based on the inclusion criteria. To
evaluate the periodontal status, the clinical parameters of
bleeding on probing (BOP), clinical attachment level (CAL),
and probing depth (PD) were measured before treatment as
well as at 2- and 4-month intervals after treatment. At the same
intervals, the immunological index of the study (serum IL-27) was
measured by special laboratory kits. The data were analyzed
using the Statistical Package for the Social Sciences, version 16SPSS 16) software. In this study, p-value < 0.05 was considered
statistically significant.
Results: The results of this study indicate that there has been
an elevation in the mean of serum IL-27 after treatment in both
treatment groups. There is no significant difference between
the levels of IL-27 in the FMD group during the study period
(p = 0.20). All periodontal indices (BOP, CAL, and PD) show
clinical improvement in each group (p < 0.001). However, no
significant difference was observed in the improvement of
periodontal indices of CAL and PD (p < 0.05).
Conclusion: According to the findings of this study, it can be
said that both FMD and Q-SRP improve the periodontal indices
and increase the serum level of the inflammatory mediator IL-27
in patients with periodontitis.
Clinical significance: Considering the benefits of the FMD
method, such as patient and dentist comfort, systemic effects,
and its cost-effectiveness, use of this method is suggested in
patients suffering from periodontitis. |
