Comparison of Adjunctive Chemomechanical Therapy With Standard Care in Patients With Periodontitis

Periodontitis Clinical Trial

Official title: Non-surgical Treatment of Periodontitis With or Without the Adjunctive Treatment of Perisolv®

Status Completed

Clinical Trial Summary

The goal of the clinical trial is to compare adjunctive chemomechanical therapy with standard care regarding root planning in patients with periodontitis. The primary outcome is to measure pocket depth before and after treatment in the test, and control group respectively Secondary outcomes: - Bleeding on probing - Plaque index - Quality of life from standardized protocol The hypothesis is that non- surgical mechanical treatment with chloramines in patients with periodontitis will show a better pocket closure after the treatment.

Clinical Trial Description

Data from the clinical treatment were registered in patient records. In parallel, clinical data were documented in a study protocol and saved in a safe in accordance with standard operation procedure at the clinic.The protocol with medical records were not opened until the study was completed and only by authorized persons with access to the data in the study such as, principal investigator and statisticians. Variables used in the study originates from an international working group in periodontology in 2018 (Papapanou PN, et al 2018). In accordance with the working group diagnosis of periodontitis should include pocket depth, bleeding, and bone loss (X-ray). Thus, in this study the primary outcomes were pocket depth and bleeding on probing. To compare scaling and root planning in periodontitis with an adjunctive application to enhance the standard care; an active comparator (Control group) was compared with an experimental arm (Test group). Patients were therefore randomized into a test or control group. Inclusion criteria - At least four pathological pockets ≥ 5 mm and bleeding on probing Exclusion criteria - Diabetes HbA1c >7.0, antibiotics 3 months before treatment, cortisone treatment and if needed prophylactic antibiotics Patients that participated in the study were consecutively given an ID code. Data was collected and registered in the ordinary patient journal. Journal entry and a research protocol was used with the unique ID number as to prevent breaches of privacy. The dental hygienist performed the treatments and was therfore not blinded. The periodontologists performed the primary and secondary outcomes within the clinical study were both blinded. The code list with the actual treatment was secured in a locked up space, at the clinic. Upon the final appointment the specific arm of treatment was registered by the dental hygienist in the patient journal. To ensure that the data from the study were correctly registered three independent dental nurses were validating the data separately. All patients were given oral and written information about the study and signed a written informed consent. The patients were informed that they could drop off whenever they wanted without any explanations. The ethical board approved the study. From a standard operation procedure by good clinical practice and Swedish legislation (The national board of social affairs and health and Health and Medical Care Act), the control group was exposed to mechanical non-surgical treatment in addition with oral hygiene instructions at baseline, 3 months, and 12 months. In the test group the same standard operation procedure was performed with the addition of Perisolv® in all pathological pockets ≥ 4 mm. Perisolv® was added initially and directly after the treatment. At all-time points both primary and secondary outcomes were determined for all pockets. In addition, the instrument Oral Health Impact Profile (OHIP) was used as a measurement of quality of life. Risk assessments was handled by the safety regulation and quality plan of the clinic.The clinic followed the Swedish legalisation, Health and Medical Care Act with quality assurance. If any adverse events during the treatments the local standard operation procedures ensured reporting to concerned authority in Sweden. Participant not fulfilling the study was reported in the patient journal as not completed and statistically noted as missing data. Regarding the study's safety plan any adverse event during the treatment code list would be decoded and would be covered by the dental insurance. From the power analysis 32 individuals were minimum to reach a clinically significant difference at 0.5 mm between the groups with alpha 0.05 and power 80%. The IBM SPSS version 27.0 statistical software package (SPSS Inc., Armonk, NY, USA) for personal computer was used in the statistical analyses. Statistics was calculated as means with standard deviation (SD). Independent t-tests (equal variance not assumed) paired t-test and one-way ANOVA test were used to compare inter and intra-group differences. Non-parametric chi-square test was used for categorical variables. Statistical significance was set with 80 percent at p < 0.05. Non visits were recorded as missing data in the statistics. ;
