Evaluation of Techniques for Scaling and Root Planing and One Stage Full Mouth Disinfection

April 27, 2014 updated by: Douglas Campideli Fonseca, Centro Universitario de Lavras

Clinical and Microbiological Evaluation of Techniques for Scaling and Root Planing Per Quadrant and One Stage Full Mouth Disinfection Associated With Azithromycin or Chlorhexidine: Randomized Controlled Trial

Evaluate and compare the effectiveness in a clinical and microbial perspective one stage full-mouth disinfection technique in relation to scaling and root planing per quadrant associated with chlorhexidine or azithromycin.

Study Overview

Detailed Description

Seventy -seven systemically healthy subjects with chronic periodontitis were randomly included in 6 different predefined groups. The following periodontal parameters were evaluated: probing depth , clinical attachment level , plaque index, gingival index and percentage of areas affected by periodontal disease. Microbiologically were evaluated the bacterial load and specific load of five bacterias: The quantification of the bacteria was performed by real-time Polymerase Chain Reaction . The clinical and microbial baseline evaluations were performed ( periodontal pre- therapy) , 90 and 180 days after treatment.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Full mouth disinfection - FMD
n = 10: Procedures for scaling and root planing were performed in a single stage (24 hours) divided into two sessions (60 min per session) on two consecutive days
Procedures for scaling and root planing were performed in a single stage (24 hours) divided into two sessions (60 min per session) on two consecutive days
Experimental: FMD + chlorhexidine (FMD-CX)
n = 15: Same as FMD with the inclusion of chlorhexidine in office (application of chlorhexidine (CX) (1%) gel in pockets after scaling, brushing tongue for 1 min. with CX (1%) gel and mouthwash at the beginning and end of each session with CX 0.2% for 30 seconds (with the form of a gargle in the last 10 seconds)). In addition, use was made of homemade CX 0.2% for 60 days after the scaling in a single phase.

Home use fo CX 0.2% for 60 consecutive days after the end of the first session of scaling.
Experimental: FMD + azithromycin (FMD-AZ)
n = 15: Same as with the FMD include the use of azithromycin (500 mg) once daily for 3 consecutive days. Medication was started the same day as the end of the scaling.
Procedures for scaling and root planing were performed in a single stage (24 hours) divided into two sessions (60 min per session) on two consecutive days
Azithromycin (500 mg) once daily for 3 consecutive days.
Experimental: Scaling and root planing (SRP)
(n = 13): scaling procedures were performed per quadrant (30 min. per quadrant) at weekly intervals between sessions;
Scaling procedures were performed per quadrant (30 min. per quadrant) at weekly intervals between sessions;
Experimental: SRP + azithromycin (SRP-AZ)
n = 11: Same as scaling and root planing group (SRP) with inclusion of the use of azithromycin (500 mg) once daily for 3 consecutive days. Medication was started the same day as the end of the last scaling hemi-arch;
Azithromycin (500 mg) once daily for 3 consecutive days.
Scaling procedures were performed per quadrant (30 min. per quadrant) at weekly intervals between sessions;
Experimental: SRP + chlorhexidine (SRP-CX)
n = 13 : Same as group scaling and root planing (SRP) with the inclusion of home use of CX 0.2% for 60 consecutive days after the end of the first session of scaling
Home use fo CX 0.2% for 60 consecutive days after the end of the first session of scaling.
Scaling procedures were performed per quadrant (30 min. per quadrant) at weekly intervals between sessions;

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in clinical attachment
Time Frame: Baseline and 180 days after treatment
In this parameter we will evaluate the distance from the cement-enamel junction to the bottom of the periodontal pocket or gingival sulcus. This measurement is made with a periodontal probe graduated in millimeters
Baseline and 180 days after treatment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in probing depth
Time Frame: Baseline and 180 days after treatment
In this parameter we will evaluate the distance between the gingival margin and the bottom of the periodontal pocket or gingival sulcus. This measurement is made with a periodontal probe graduated in millimeters
Baseline and 180 days after treatment
