I-Smads in Periodontitis

April 15, 2021 updated by: Figen Öngöz Dede, Bulent Ecevit University

Role of Inhibitor SMADs in Stage 3 Grade B Periodontitis Before and After Periodontal Treatment

Recently, it has been stated that Smads play an active role in all conditions where transforming growth factor-beta (TGF-β) is involved, including periodontal inflammation. This study aimed to examine the levels of TGF-β and inhibitor Smads in saliva and gingival crevicular fluid (GCF) in patients with Stage 3 Grade B periodontitis before and after non-surgical periodontal treatment. Twenty (20) stage 3 grade B periodontitis and 20 periodontally healthy individuals were included in the study. Clinical periodontal measurements were recorded; periodontitis patients received non-surgical periodontal treatment, and GCF and saliva samples were obtained at baseline and one month after treatment. TGF-β, Smad6, and Smad7 were determined by ELISA.

Study Population

  1. group (Control): Periodontally and systemically healthy
  2. group: Systemically healthy and periodontitis

Description

Inclusion Criteria:

  • Have at least 20 natural teeth, excluding third molars.
  • Periodontitis patients had at least two non-adjacent sites per quadrant with probing depth (PD) ≥ 5 mm and clinical attachment level (CAL) ≥ 5 mm with gingival inflammation, and alveolar bone loss affecting >30% of the teeth, as detected on clinical and radiographical examinations.
  • Periodontally healthy control group had no sign of gingival inflammation, no PD > 3mm and no evidence of attachment or bone loss

Exclusion Criteria:

  • History of systemic disease.
  • Regular use of any drugs which can effect the immune system or inflammatory response in the 6 months preceding the start of the study.
  • Periodontal treatment during last 6 months that could affect periodontal status.
  • Smoking.
  • History of radiotherapy or chemotherapy.
  • Current pregnancy, lactation or menopause.
