Brief Summary:
The purpose of this research project is to gain information on the best and most comfortable way to treat the periodontal disease. The main objective is to compare the efficacy of conventional scaling and root planning compared to laser scaling for the non-surgical treatment of periodontal disease. Both therapies have shown to be effective and are regularly used in the dental clinic.

Condition or disease Intervention/treatment Phase
Generalized Moderate Chronic Periodontitis Generalized Severe Chronic Periodontitis Periodontal Diseases Procedure: Scaling and root planing Device: Er:YAG Laser Device: Hand instruments Not Applicable

Detailed Description:
The study has been designed as a single blinded split-mouth randomized controlled clinical trial. Patients will be randomized prior to treatment, to which the examiner will be blinded. Clinical parameters will be recorded at baseline and 3 months after treatment has been completed. At the time of recruitment, inclusion/exclusion criteria checklist, informed consent and baseline measurements will be obtained and recorded. Medical history will be updated and radiographs will be reviewed or taken. During the second appointment, conventional scaling and root planing will be performed in the corresponding quadrant; during the third appointment, laser therapy will be conducted, 1 month after, during the forth appointment, a follow up (no measurements) will be scheduled with provider, and 3 months after scaling completion, measurements will be taken and periodontal maintenance performed. Patient will receive home care instructions at every visit and will fill out a visual analogue scale at baseline, 1 month and 3 month visit.

Arm Intervention/treatment
Active Comparator: Scaling and Root Planing with Hand Instruments
Patients will undergo scaling and root planing with hand instruments (half of their mouth, following a split-mouth design)
Procedure: Scaling and root planing
A non-surgical procedure that treats periodontal disease, sometimes called a deep cleaning, is considered the "gold standard" (standard of care) of treatment for patients with chronic periodontitis.
Other Name: Deep cleaning

Device: Hand instruments
11/12 and 13/14 gracey, 4R/4L curette and sickle - standard of care choices for performing scaling and root planing.
Other Name: Hand instrumentation

Experimental: Er:YAG Laser Scaling
Patients will undergo scaling and root planing with Er:YAG Laser in the untreated half of their mouth.
Procedure: Scaling and root planing
A non-surgical procedure that treats periodontal disease, sometimes called a deep cleaning, is considered the "gold standard" (standard of care) of treatment for patients with chronic periodontitis.
Other Name: Deep cleaning

Device: Er:YAG Laser
This laser is intended to be used for dental surgery. The Er:YAG Laser emits an infrared beam which is readily absorbed by water contained by both hard and soft tissues of the human body. As a result, energy of the laser beam instantly vaporizes the water molecules in soft and hard tissues of the tooth and surrounding tissues causing the tissues to crumble away or resection of the soft tissues of gingival.
Other Name: Erbium-doped Yttrium Aluminium Garnet Laser

Primary Outcome Measures :
  1. Change in Clinical Attachment Level (CAL) [ Time Frame: Recorded at baseline and 3 months after treatment ]
    Calculated based on distance from CEJ to gingival margin and the pocket depth (site specific measurement)

  2. Change in Pocket Depth (PD) [ Time Frame: Recorded at baseline and 3 months after treatment ]
    Measured at 6 sites per tooth in millimeters (mm) (site specific measurement)

Secondary Outcome Measures :
  1. Change in Plaque Index (PI) [ Time Frame: Recorded at baseline and 3 months after treatment ]
    Plaque and calculus accumulation on tooth surfaces (site specific measurement)

  2. Difference in timing [ Time Frame: During the time both therapies are performed ]
    Timing spent performing the 2 different types of therapy

  3. Differences in sensitivity [ Time Frame: VAS completed at baseline, 1 month follow up and 3 months re-evaluation ]
    Visual Analogue Scale (VAS) from 0-10 and 4 multiple choice questions to assess patient's sensitivity and their level of satisfaction and preference towards both modalities.

  4. Change in Bleeding on Probing (BoP) [ Time Frame: Recorded at baseline and 3 months after treatment ]
    Bleeding after probing the pocket (site specific measurement)
