Conditions

chronic periodontitis and pocket depths of 4-6 mm. Chronic periodontitis

Interventions

Intervention 1: One side of each patient is randomly selected as the laser group (SRP + laser). Intervention 2: Control group: the other side of the patient is considered as the control group.

Eligibility

Sex/Gender

All

Age

18 Years to No maximum

Inclusion criteria

Inclusion criteria: patients older than 18 years with chronic periodontitis with pocket depths of 4-6 mm in at least four teeth per jaw quadrant.

Exclusion criteria

Exclusion criteria: Patients who have received periodontal treatment over the 12 months preceding the study those who have consumed antibiotics or anti-inflammatory drugs within the past month patients with systemic disorders pregnant, smokers or alcohol drinkers patients having partial dentures

Design outcomes

Primary

Measure	Time frame
Bleeding on probing (BOP):. Timepoint: before the treatment (baseline), at 6 and 18 weeks later. Method of measurement: The periodontal probe is inserted approximately 2 mm into the gingival sulcus at the buccal surface of each tooth.;Probing depth (PD). Timepoint: before the treatment (baseline), at 6 and 18 weeks later. Method of measurement: The periodontal probe is placed in the gingival sulcus and enters as far as possible into the pocket. The pocket depth is recorded in millimeters.;Plaque index (PI). Timepoint: before the treatment (baseline), at 6 and 18 weeks later. Method of measurement: To determine PI, plaque detection tablets are used. The plaque index is calculated by dividing the number of plaque containing surfaces by the total number of available surfaces (four surfaces ) and multiplying the result by 100.	—

Secondary

Measure	Time frame
Clinical attachment level (CAL):. Timepoint: before the treatment (baseline) as well as at 6 and 18 weeks later. Method of measurement: CAL is determined by measuring the distance in millimeters from the cementoenamel junction (CEJ) to the bottom of the periodontal pocket using a periodontal probe.	—
