Clinical Trial Summary
The use of nonsurgical periodontal treatment, together with plaque control is considered the
gold standart for the treatment of periodontal diseases; it produces beneficial effects such
as reductions in clinical inflammation, decreases in pocket depth and increases in clinical
attachment levels .However to modulate the healing response additional protocols has been
suggested to increase the efficacy of existing treatment protocols. Laser biostimulation
therapy is highly preferred method used due to its healing acceleration effect on several
wounds in medical field. Thus,the investigators aimed to evaluate the laser biostimulation
therapy adjunct to non-surgical periodontal treatment in systemically healthy and
uncontrolled type 2 diabetes mellitus patients with generalized periodontitis. The effects of
laser irradiation with Nd-YAG laser at the 1064-nm wavelength as an adjunct to non-surgical
periodontal treatment (NSPT) was analysed by means of IL-1β and IL-10 concentrations in
gingival crevicular fluid and periodontal clinical measurements of systemically healthy and
uncontroled DM2 patients with generalized periodontitis.
Description:
Today, the one that stands out the most among these protocols is laser application which was
concluded to be a support or be an alternative treatment approach to standart periodontal
treatments . As the laser biostimulation therapy(LBT) has been investigated by means of
anti-inflammatory and healing promotion action on periodontal tissues, the LBT adjunct to
non-surgical periodontal treatment of diabetic patients expected to create positive healing
effects. The biostimulation effect of laser on tissue healing has drawn significant
attention, not only in healthy individuals but also in patients with systemic problems
causing impaired wound healing such as diabetes mellitus . Patients with poor metabolic
control frequently present impaired wound healing and using LBT as a treatment method for
diabetic ulcers have shown positive healing effects . However, there has been little
knowledge about the additional benefits of LBT on healing proccess or inflammatory response
among patients with uncontrolled diabetes mellitus type 2 receiving periodontal treatment.
In the light of the current knowledge, the impaired wound healing seen in diabetic patients
may be a reason to require an additional approach in periodontal treatment like
biostimulation of periodontal tissues by several ways. In order to determine the healing
response, the investigators aimed to evaluate the effects of LBT irradiation with Nd-YAG
laser at the 1064-nm wavelength as an adjunct to non-surgical periodontal treatment (NSPT) by
means of periodontal clinical measurements and gingival crevicular fluid cytokine levels
(IL-1β and IL-10) in systemically healthy and uncontroled DM2 patients with generalized
periodontitis .
The study was designed as a split-mouth randomized, controlled, double-blind clinical study.
The study protocol was approved by the Local Ethics Committee of Ondokuz Mayıs University and
Turkey Ministry of Health, Drug and Medical Device Agency . The written informed consent was
obtained from all study participants in accordance with the Helsinki Declaration .
All participants with periodontitis received NSPT. Non-surgical periodontal treatment
consisted of conventional quadrant scaling in four session of 30 min, each on a weekly basis,
using scalers, curettes and ultrasonic devices.
Laser Biostimulation treatment (LBT) and Sham application: Following NSPT, either the left or
right side of each periodontitis patient was randomly selected (by coin toss) to receive LBT
or sham treatment. LBT was performed six times (on the same day 30 which was the last
scalling and root planning session and repeated weekly for 5 more times) using a 1064 nm
Nd.YAG laser (Fotona AT Fidelis III,Ljubljana, Slovenia).
Clinical Measurements and Gingival creviculat fluid (GCF) Sampling Clinical measurements were
performed before NSPT (baseline) and on days 30, 37 and 72 of the follow-up for both DM2 and
SH groups. The following clinical periodontal measurements were recorded Silness & Löe plaque
index (PI), Löe & Silness gingival index(GI), probing pocket depth (PPD); clinical attachment
level (CAL); bleeding on probing (BOP). A Williams periodontal probe (Nordent Manufacturing
Inc., Elk Grove Village, IL, USA) calibrated in mm was used to measure 6 sites on each
selected tooth (mesio-buccal, mid-buccal, disto-buccal, mesio-lingual, mid-lingual,
disto-lingual locations). For each tooth, the side with the highest PPD and CAL values were
identified, and the additional clinical measurements and GCF sampling were performed on this
side in both LBT and sham application of the patients. (total: 30 teeth in DM2 group, 30
teeth in SH group). GCF samples were collected before NSPT treatment(baseline) and on Days
30, 37 and 72 of follow-up. Sampling sites were isolated with cotton rolls, saliva was
removed, and supragingival plaque, if present, was removed using a sterile curette. GCF was
sampled by placing a strip of filter paper (Periopaper, ProFlow, Inc., Amityville, New York,
USA) into the crevice until mild resistance was felt and then leaving it in position for 30
seconds. The GCF volume of each strip was determined by electronic impedance (Periotron 8000,
ProFlow, Inc.), and samples were then placed in sterile polypropylene tubes and stored at
-70°C until analysis.
Amounts of IL-1β and IL-10 in each GCF sample were evaluated using standard enzyme-linked
immunosorbent assays (ELISA) according to the manufacturers' instructions.
