About this study
Official title: Comparison of the Effect of Teflon vs Non-Teflon Hand Scalers in the Maintenance of Peri-Implant Tissue: A Randomized Clinical Trial
The buccal and lingual surface of the 23 participants' crowns will be randomly assigned to receive scaling and root planing with either Teflon scalers, or non-Teflon scalers after implant crown delivery. Each patient will act as their own control.
Patients will receive scaling and root planing at 3, 6, 9 and 12 months by a calibrated dental hygienist. All surfaces of the implant will be debrided for 1 minute using a transversal movement. Each patient will receive oral hygiene instructions by the hygienist at the end of each maintenance therapy appointment. The participants will be instructed to use a Modified Stillman brushing technique twice per day and cross shoe shine flossing motion once per day. Each patient will be provided with a three-month home care kit with dental aids. These aids will consist of toothpaste, a toothbrush and implant floss.

Measurements will be taken at 0, 3, 6, 9 and 12 months by a calibrated periodontal resident. The parameters assessed at the implant site and patient level will be modified plaque index (IPI) by Mombelli, modified gingival index (IBOP) by Mombelli, implant probing depths (PD) at six sites, presence of keratinized gingiva (KT), recession (REC), Full mouth plaque index (FPI) and Full mouth bleeding on probing (FBOP).
The Peri-implant Crevicular Fluid will be collected at 0, 3, and 12 months by isolating the implant site from saliva and introducing Periopaper strips into the buccal, mesial, distal and lingual sites of the implant sulcus for 30 seconds. The strips will be placed in a sealed Eppendorf tubes and transported by portable freezer to the laboratory where they will be stored at -86 degrees Celsius. The Periopaper samples will be treated for the detection and quantification of the following cytokines: Interleukin-2, Interleukin-4, Interleukin-6, Interleukin-8, Interleukin-10, Tumor Necrosis Factor alpha and Interferon gamma.
Periapicals will be taken at baseline and 12 months. All radiographs will be standardized.
After 12 months, the implant crown will be removed and the implant crown's surface alterations will be evaluated using atomic force microscopy (AFM) using the RA, or average roughness, and the RZ, or mean roughness depth, scores. The implant crown surface will then be repolished/reglazed and delivered back to the patient's mouth. Crowns will be evaluated before delivery to determine adequate level of smoothness.
Based on the presence of cytokines in the Peri-implant Crevicular Fluid, the degree of surface alterations, the modified plaque index, implant probing depths, full mouth plaque index, and full mouth bleeding on probing, we can determine if scratching affects the inflammation around the screw retained dental implant.

What is being measured
The primary outcome is the main question the study is designed to answer.
Degree of surface roughness
The implant crown's surface alterations will be evaluated using atomic force microscopy (AFM) using the average roughness (Ra) and the mean roughness depth (Rz), scores. Crowns will be evaluated before delivery to determine adequate level of smoothness. For our study, Ra and Rz should range from 0.1µm to 0.5µm. Higher values represent more scratching.
Measured: 12 months

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The buccal and lingual surface of the 23 participants' crowns will be randomly assigned to receive scaling and root planing with either Teflon scalers, or non-Teflon scalers after implant crown delivery. Each patient will act as their own control.
Patients will receive scaling and root planing at 3, 6, 9 and 12 months by a calibrated dental hygienist. All surfaces of the implant will be debrided for 1 minute using a transversal movement. Each patient will receive oral hygiene instructions by the hygienist at the end of each maintenance therapy appointment. The participants will be instructed to use a Modified Stillman brushing technique twice per day and cross shoe shine flossing motion once per day. Each patient will be provided with a three-month home care kit with dental aids. These aids will consist of toothpaste, a toothbrush and implant floss.
Measurements will be taken at 0, 3, 6, 9 and 12 months by a calibrated periodontal resident. The parameters assessed at the implant site and patient level will be modified plaque index (IPI) by Mombelli, modified gingival index (IBOP) by Mombelli, implant probing depths (PD) at six sites, presence of keratinized gingiva (KT), recession (REC), Full mouth plaque index (FPI) and Full mouth bleeding on probing (FBOP).
The Peri-implant Crevicular Fluid will be collected at 0, 3, and 12 months by isolating the implant site from saliva and introducing Periopaper strips into the buccal, mesial, distal and lingual sites of the implant sulcus for 30 seconds. The strips will be placed in a sealed Eppendorf tubes and transported by portable freezer to the laboratory where they will be stored at -86 degrees Celsius. The Periopaper samples will be treated for the detection and quantification of the following cytokines: Interleukin-2, Interleukin-4, Interleukin-6, Interleukin-8, Interleukin-10, Tumor Necrosis Factor alpha and Interferon gamma.
Periapicals will be taken at baseline and 12 months. All radiographs will be standardized.
After 12 months, the implant crown will be removed and the implant crown's surface alterations will be evaluated using atomic force microscopy (AFM) using the RA, or average roughness, and the RZ, or mean roughness depth, scores. The implant crown surface will then be repolished/reglazed and delivered back to the patient's mouth. Crowns will be evaluated before delivery to determine adequate level of smoothness.
Based on the presence of cytokines in the Peri-implant Crevicular Fluid, the degree of surface alterations, the modified plaque index, implant probing depths, full mouth plaque index, and full mouth bleeding on probing, we can determine if scratching affects the inflammation around the screw retained dental implant.

Questions about this trial
What is this clinical trial studying?
A study testing Types of scalers in people with Surface Roughness and Maintenance of Dental Implants, run by University of Manitoba at 1 site in Canada.
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 3 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 16 Aug 2019. 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 Canada. 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?
Degree of surface roughness (time frame: 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03316937, which also lists 16 linked publications.
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 16 Aug 2019.
