Interventions

Non-surgical periodontal therapy. Two different protocols were used: Test group: A full-mouth session of scaling and root planing (SRP) with ultrasounds plus the use of the Er:YAG laser in initial poc

Eligibility

Sex/Gender
All

Inclusion criteria

Inclusion criteria: 1. Males and females over 18 years old. 2. Diagnosis of chronic periodontitis based on the presence of at least 4 teeth per quadrant with PPD=4.5 mm and radiographic bone loss between 30-50% in more than 30% of teeth.

Exclusion criteria

Exclusion criteria: 1. Systemic diseases requiring antibiotic prophylaxis or other systemic medication that could affect the subject?s clinical response. 2. Pregnant women or in breastfeeding period. 3. Periodontal treatment within the last 12 months or systemic antibiotic intake in the last 3 months. 4. Not willing to participate in the study

Design outcomes

Primary

MeasureTime frame
Changes in probing pocket depth (PPD): PPD was recorded with an electronic periodontal probe (Florida Probe®, Gainesville, FL, USA) using a controlled force of 25 gr and measured to the closest 0.5 mm. This electronic probing system has two description modes, the graphic display and the data mode. In the graphic display, it automatically segments PPDs in three categories: shallow (1-4 mm), moderate (5-6 mm) and deep (=7 mm). In the data mode, the moderate category, however, starts when PPDs = 4.5 mm. In this investigation PPDs = 4.5 mm in the data mode (equivalent to = 5 mm in the graphic display) were selected for laser application in the test group.

Secondary

MeasureTime frame
1. Changes in the proportion of moderate-deep pockets (% PPD=4.5) 2. Changes in the proportion of open pockets (% PPD=4.5+positive bleeding on probing) 3. Changes in gingival recession (REC): the distance between the gingival margin (GM) and the cemento-enamel junction (CEJ) or the margin of the restoration. A negative value was given when the GM was located coronal to the CEJ. 4. Changes in clinical attachment level (CAL): This was calculated as the addition of PPD plus REC. 5. Changes in bleeding on probing (BOP): Measuring presence/absence of bleeding within 15 s after probing. 6. Changes in plaque index: Absence/presence of plaque after staining with erythrosine (Plac Control®, Dentaid, Barcelona, Spain). Both primary and secondary outcome measurements were carried out at baseline, 3, 6 and 12 months.
