About this study

Official title: Combined Application of ER:YAG and ND:YAG Lasers in Treatment of Chronic Periodontitis: A Split-mouth Randomized Controlled Trial

The aim of the present study was to compare the effectiveness of combined Er:YAG and Nd:YAG laser therapy to that of scaling and root planning with hand instruments in nonsurgical treatment of chronic periodontitis.

Read the detailed description

The aim of the present study was to compare the effectiveness of combined Er:YAG and Nd:YAG laser therapy to that of scaling and root planning with hand instruments in nonsurgical treatment of chronic periodontitis.Twenty-five systemically healthy patients with moderate-to-advanced periodontal destruction were selected for this study. The quadrants were randomly allocated in a split-mouth design to either combined Er:YAG (160 mj/pulse, and 10 Hz) and Nd:YAG laser (100 mJ/pulse, and 20 Hz) therapy (test group) or scaling root planning using hand instruments (control group). At baseline, 1 month, and 3 months after treatment, clinical measurements, including plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment level (CAL), and bleeding on probing (%) (BOP), were performed and gingival crevicular fluid and subgingival plaque samples were taken. The gingival crevicular fluid levels of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) were analyzed by enzyme-linked immunosorbent assay. Total antioxidant status (TAS)/total oxidant status (TOS) were analyzed by high-performance liquid chromatography and a novel automatic colorimetric method. Quantitative analysis of Porphyromonas gingivalis (Pg), Tannerella forsythia (Tf), and Treponema denticola (Td) was performed using real-time polymerase chain reaction (PCR) procedures.

Study groupRoleWhat they receive
Control GroupActive comparatorMechanical periodontal treatment: Scaling and root planing were performed with periodontal curettes until the operator feels that root surface is clean, hard and smooth.
Receives: Device: Periodontal curettes
Test GroupExperimentalCombined laser therapy: An Er:YAG laser (160 mj/pulse, 10 Hz) (AT Fidelis Fotona, Ljubljana, Slovenia) with water irrigation was first used to remove subgingival calculus and infected cementum.The Er:YAG laser beam was delivered into the periodontal pockets using a chisel-shaped quartz tip in contact mode under water irrigation, from a coronal to an apical direction with the tip inclined at 10o to 15o to the root surfaces. After Er:YAG laser application, Nd:YAG laser treatment (AT Fidelis Fotona, Ljubljana, Slovenia) was performed at an energy level of 100 mJ/pulse, and 20 Hz for removing pocket epithelium and detoxification purpose. Irradiation was accomplished with a 320 μm fiber optic delivery system. The fiber was inserted into the periodontal pocket base in parallel alignment with the root surface, and the fiber was slowly moved from apical to coronal in a sweeping motion during the laser light emission.
Receives: Device: Er-YAG+Nd-YAG lasers

Questions about this trial

What is this clinical trial studying?

A study testing Periodontal curettes and Er-YAG+Nd-YAG lasers in people with Chronic Periodontitis, run by Izmir Katip Celebi University.

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 1 inclusion and 1 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 7 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.

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?

Yes. Results are posted in the registry (first posted 7 Nov 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Clinical Attachment Level Change for Moderately Deep Pockets (4 mm≤PD≤6 mm) (time frame: Baseline, 1 and 3 months). The study lists 2 primary outcomes in all. 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 7 Nov 2017.
