简要总结

Participants with periodontitis and presence of bilateral intrabony defect will be randomised to have one side of the mouth undergo root surface debridement using hand instruments and ultrasonic scaler alone, while the contralateral side will receive the same treatment, with the addition of the Er:YAG laser. Outcomes studies will be periodontal clinical parameters at 3 months, 6 months, 9 months and 12 months after treatment, radiographic parameters at 12 months, patient-reported parameters and laboratory analyses.

详细描述

The study is a Double-masked randomised controlled trial with split-mouth design.

Participants with periodontitis will be randomised to have one side of the mouth undergo root surface debridement using hand instruments and ultrasonic scaler alone, while the contralateral side will receive the same treatment, with the addition of the Er:YAG laser. Outcomes studies will be periodontal clinical parameters at 3 months, 6 months, 9 months and 12 months after treatment, radiographic parameters at 12 months, patient-reported parameters and laboratory analyses.

盲法说明

Randomisation for the site receiving the additional test procedure (laser) will be carried out between baseline and visit 2. The randomisation will be carried out by Postgraduate Students independent of the study. Random permuted block sizes of 4 will be employed. The centralised randomisation service 'Sealed envelope' will be used for randomisation and to ensure allocation concealment. A sealed envelope will be enclosed with the patient's notes by personnel not directly involved in the study. The therapist will only be informed about treatment allocation by opening the envelope following completion of non-surgical therapy (when the laser will need to be employed on the test site). No minimization or stratification is planned. The randomisation code will only be revealed after statistical analysis. The randomisation will be done by a different postgraduate student who will be masked and is not involved in the study.
