Participant Flow

The same 26 patients received both interventions. Each patient's right and left sides (mouth quadrants) were randomly assigned to receive one of the two treatment modalities using random sequences generated by a software application: conventional scaling and root planing (C-SRP), or conventional scaling with Er:YAG laser-assisted scaling and root planing (L-SRP).

Unit of analysis: mouth quadrant

Conventional Scaling and Root Planing
Conventional Scaling and Root Planing with hand instruments were randomly assigned to the left or the right mandible side in a split-mouth randomized design. 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. Hand instruments: 11/12 and 13/14 gracey's, mini 11/12 and 13/14 gracey's, 4R/4L curette and sickle scaler - the standard of care choices for performing scaling and root planing.
Er:YAG
Conventional Scaling and Root Planing with Er:YAG laser were randomly assigned to the left or the right mandible side in a split-mouth randomized design. 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.

Patients will undergo a split-mouth design, with one half side of the mouth (one side has 2 quadrants which include the upper and lower mouth) receiving non-surgical treatment with conventional scaling and root planing with hand instruments, and the other half side of their mouths receiving non-surgical treatment with conventional scaling and root planing with Er:YAG laser.

SECONDARY outcome

Timeframe: Baseline and 3 months

Population: 9 patients experienced no differences in sensitivity according to the modality.

A numeric scale was completed by participants to assess their degree of sensitivity or pain with a modified 0 - 10 scale (i.e.: 0- no pain/sensitivity; 5- moderate pain or sensitivity, may require medication; 10- unbearable sensitivity or pain that impairs my sleep). Baseline and 3 months reported scores were compared within each patient and between modalities. The numbers reported are participants that experienced a better improvement in sensitivity within the respective modality.
