NCT04847830

Brief Summary

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.

Study Arms (2)

Laser

EXPERIMENTAL

One side of the mouth will undergo root surface debridement using hand instruments and ultrasonic scaler, with the addition of the Er:YAG laser

Device: Er:YAG laser (Waterlase)Procedure: root surface dbridement

Control

PLACEBO COMPARATOR

The other side of the mouth undergo root surface debridement using hand instruments and ultrasonic scaler alone

Procedure: root surface dbridement

Interventions

The WaterLase iPlus tissue cutting system is a unique device with diverse, hard- and soft-tissue dental applications. It utilizes advanced laser and water atomization technologies to safely and effectively cut, shave, contour, roughen, etch, and resect oral hard-tissue, and direct laser energy to perform oral soft-tissue removal, incision, excision, ablation and coagulation.

Masking Details
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.
