Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
To eliminate any bias, the investigators will initially hypothesize that there is no difference in periodontal status, jawbone remodeling, tooth sensitivity, pain and quality of life in patients having teeth with chronic periodontitis and receiving LLLT with orthodontic treatment versus teeth undergoing orthodontic treatment without incorporation of LLLT.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
LLLT group
LLLT group: orthodontic treatment and low-level laser therapy
low-level laser therapy
The test teeth will receive LLLT using a 940 nanometer diode laser (EZLASE; BIOLASE Technology Inc., Irvine, CA, USA) with output power of 330 milliwatt. The experimental side was irradiated for 30 s in two sessions, delivering an energy density of 7 Joules per square centimeter.
orthodontic treatment
Orthodontic treatment will be carried out using preadjusted appliances with bonded 0.022×0.028-square inch brackets/buccal tubes and 0.014-inch NiTi archwires as the first archwires. The treatment or the major part of the treatment will be completed in 12 months.
control group
Control group: orthodontic treatment and no laser treatment.
orthodontic treatment
Orthodontic treatment will be carried out using preadjusted appliances with bonded 0.022×0.028-square inch brackets/buccal tubes and 0.014-inch NiTi archwires as the first archwires. The treatment or the major part of the treatment will be completed in 12 months.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. No medications required for periodontal therapy and no use of any antibiotic and/or anti-inflammatory medication in the preceding month;
3. Chronic periodontitis with at least two pairs (clinically matched) displaced single-rooted teeth (each pair of teeth is in the same arch but in two contralateral hemi-arches respectively belonging to the same tooth typology) having at least one site probing depth of 5 mm or more, interproximal attachment loss of 3 mm or more, and radiographic signs of alveolar bone loss.
4. Periodontal status confirmed by periodontal evaluation remains stable for at least 6 months after complete periodontal treatment.
Exclusion Criteria
2. pregnancy;
3. under orthodontic treatment.
