Trial summary

Activin-A belongs to the transforming growth factor-beta superfamily and is a multifunctional cytokine that plays a role in inflammation, immune response, tissue repair and regeneration. Proinflammatory cytokine interleukin-1beta (IL-1β) can increase Activin-A expression in various cell types. Read more about this study

About this study

Official title: Oral Biofluid Levels of Activin-A and Interleukin-1 Beta Levels in Periodontal Health and Disease

Activin-A belongs to the transforming growth factor-beta superfamily and is a multifunctional cytokine that plays a role in inflammation, immune response, tissue repair and regeneration. Proinflammatory cytokine interleukin-1beta (IL-1β) can increase Activin-A expression in various cell types. This study aims to evaluate gingival crevicular fluid (GCF) and salivary Activin-A and IL-β levels in stage III periodontitis. Seventy-five systemically healthy and non-smoker volunteers consisting of 23 stage III periodontitis, 26 gingivitis and 26 periodontally healthy were enrolled. Full-mouth clinical periodontal indices were recorded, unstimulated whole saliva and GCF samples were obtained, Activin-A and IL-1β total amounts were determined by enzyme-linked immunosorbent assay. Statistical comparisons were performed using non-parametric tests.

Read the detailed description

Participants were divided into three groups according to the diagnostic criteria proposed by the Classification of Periodontal and Peri-implant Diseases and Conditions; I. Periodontitis group (n=23), II. Gingivitis group (n=26) III. Periodontally healthy group (n=26)

Clinical periodontal indices included probing depth (PD), clinical attachment loss (CAL), the dichotomous scoring of bleeding on probing (BOP +/-), gingival index (GI), and plaque index (PI). Clinical recordings were performed at six points (mesiobuccal, buccal, distobuccal, mesiopalatal/mesiolingual, palatal/lingual, and distopalatal/distolingual) of all teeth, except the 3rd molars, by a single investigator using a conventional periodontal probe.

Interproximal radiographic bone loss on the digital panoramic radiographs were evaluated, as the ratio of the distance between the bone crest and the cemento-enamel junction to the length of the root.

GCF and unstimulated whole saliva samples were obtained 1 day following the clinical periodontal measurements. Immediately after saliva collection, GCF was collected from the buccal aspects of non-contiguous interproximal sites in two single-rooted teeth via steril paper strips. Fluid samples were obtained from two deepest pockets in periodontitis group and the most inflamed sites with clinical signs of redness or edema in gingivitis group. In the periodontally healthy groups, samples were taken from the sites without visible inflammation. All samples were stored at -80 °C until further analysis.

Measurement of Activin-A and IL-1β levels in GCF and saliva samples were performed by the commercially available enzyme-linked immunosorbent assay (ELISA) kits. While GCF cytokine levels were expressed as both total amounts at two samples per 30 s and concentrations, salivary cytokine levels were presented as concentrations.

A statistical software package was used for all data analyses. If the clinical and biochemical data did not present normal distribution as checked by Shapiro Wilk's normality test, the analyses were performed by using nonparametric methods. The Kruskal-Wallis test with Dunn-Bonferroni post hoc method was applied to compare the study groups regarding clinical indices and oral biofluid levels of Activin-A and IL-1β. The presence and degree of linear association of cytokine levels in GCF and saliva with clinical indices were analyzed by Spearman rank correlation coefficient. p<0.05 was considered as a threshold for statistical significance.

What participants receive

    Clinical periodontal indices included probing depth (PD), clinical attachment loss (CAL), the dichotomous scoring of bleeding on probing (BOP +/-), gingival index (GI), and plaque index (PI). Clinical recordings were performed at six points (mesiobuccal, buccal, distobuccal, mesiopalatal, palatal, and distopalatal) of all teeth, except the 3rd molars.

    GCF and saliva samples were obtained 1 day following the clinical measurements. Unstimulated whole saliva was collected from all participants. GCF was sampled with paper strips from two deepest pockets in periodontitis group; the most inflamed sites with clinical signs of redness or edema in gingivitis group; and the sites without visible inflammation in periodontally healthy group. GCF and saliva samples were stored at -80 °C until further analysis.

Study groups in NCT06110221
Study groupRoleWhat they receive
PeriodontitisThis group consisted of patients with generalized stage III periodontitis, who had interproximal CAL≥5 mm and PD≥6 mm as well as radiographical bone loss extending to the mid-third of the root or beyond at 30% of the teeth or more. CAL was not caused by trauma-related gingival recession, dental caries extending into the cervical areas of the teeth, endodontic lesions draining through the marginal periodontium, and the distal bone loss in adjacent second molars due to extractions of third molars. They showed no more than four teeth loss due to periodontitis.
Receives: Other: Periodontal clinical measurements, GCF and saliva sampling
GingivitisThis group demonstrated no detectable interproximal CAL or radiographical bone loss. PD was ≤3 mm and BOP (%) was ≥30% in the entire mouth.
Receives: Other: Periodontal clinical measurements, GCF and saliva sampling
Periodontal healthThis healthy control group had an intact periodontium without detectable CAL and radiographical bone loss. PD was ≤3 mm and BOP (%) was <10% in the entire mouth.
Receives: Other: Periodontal clinical measurements, GCF and saliva sampling

Questions about this trial

What is this clinical trial studying?

An observational study of Periodontitis and Gingivitis, run by Aydin Adnan Menderes University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

GCF Activin-A levels (time frame: 24 hours after clinical periodontal measurements). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Oct 2023.
