Conditions
Brief summary
Patients often find having their teeth scaled an unpleasant experience. The purpose of this research is to determine whether a laser is as effective as conventional instruments (powered and hand scalers) for the treatment of chronic periodontitis (gum disease). The effectiveness of each treatment method will be assessed using patient-centred outcomes such as clinical periodontal measurements and patients’ overall experience. The study design is such that it is as close to normal daily practice as possible.
Interventions
Using a split-mouth design each patient’s mouth will be divided into test and control quadrants.
The test quadrants will be debrided using an Er:YAG laser (KEY3®, Kavo, Biberach, Germany).The laser parameters are set at an energy level of 160mJ/pulse and a repetition rate of 10Hz. The Kavo periodontal P2061 handpiece will be used with water irrigation. The operator chooses the Kavo fibre tips as the situation dictates.

The test quadrants will be debrided using an Er:YAG laser (KEY3®, Kavo, Biberach, Germany).The laser parameters are set at an energy level of 160mJ/pulse and a repetition rate of 10Hz. The Kavo periodontal P2061 handpiece will be used with water irrigation. The operator chooses the Kavo fibre tips as the situation dictates. All treatments will be terminated when the operator is satisfied that the root surfaces are smooth and thoroughly debrided. An independent examiner will verify the clinical end point. There will be no time limit for instrumentation.

Inclusion criteria
All participants will have a minimum 16 teeth (4 per quadrant) and a diagnosis of moderate or advanced chronic periodontitis defined as PD =5mm, attachment loss of =2mm and bleeding on probing in 6 or more sites distributed throughout the mouth. They will be in good general health, and will have received no periodontal treatment within the previous 6 months. All patients must comprehend the visual analogue scale (VAS) and will sign informed consent forms.
Exclusion criteria
Patients will be excluded from the study if they suffer from systemic diseases which could influence the outcome of therapy; require antibiotic coverage prior to dental treatment; use of medications such as antibiotics, steroids and anti-inflammatories in the 3 months prior to treatment; are pregnant; or are heavy smokers ( = 10 cigarettes per day).
