The Effects of Diode Laser as an Adjunct to Non-surgical Periodontal Treatment on Periodontal Status in Patients With Stage III-IV Periodontitis: a Randomized Controlled Trial

Periodontal disease is serious and global chronic disease. The prevalence of periodontal diseases in United Arab Emirates is not clear but data from Dubai Health Authority showed that one in five patients has received periodontal treatment in recent years. Several studies reported the additional benefits provided by the use of diode laser in combination with ultrasonic debridement in the treatment of gum disease. The use of diode laser may debridement of deep pocketing areas while improving healing of gum tissues. The aim of the study is to compare the effect of removing bacterial deposit (biofilm) from deep tooth pocket using combined diode laser and conventional pocket debridement versus conventional pocket debridement alone on tooth supporting tissue parameters in patients with advanced gum disease (periodontitis). Methodology: A total of 22 patients with advanced gum disease will be randomly allocated to two groups: a control group, which will receive conventional pocket debridement and a test group which will receive ultrasonic debridement with diode laser. Gum measurements will be recorded by a masked calibrated examiner at six points for each tooth and patients' postoperative experience and satisfaction will be assessed using special forms.

Combined use of diode laser device and scaling instruments to remove plaque and calculus from the surface of the roots of teeth.

The plaque score is calculated by expressing as a percentage the number of surfaces harbouring plaque related to the total number of tooth surfaces.

The bleeding score is calculated by expressing as a percentage the number of sites that bleed upon probing in relation to the total number of tooth sites.

PPD is the depth from the free gingival margin to the base of the sulcus and it is measured in millimeters at several locations around the whole circumference of the tooth.

CAL is calculated from a fixed reference point (cementoenamel junction or CEJ), and it is computed by calculating the distance from the CEJ to the base of the pocket in millimeters.

Number of sites with PPDs ≥ 6 mm. PPD is the depth from the free gingival margin to the base of the sulcus and it is measured in millimeters at several locations around the whole circumference of the tooth.

Percentages of sites with PPDs ≥ 6 mm. PPD is the depth from the free gingival margin to the base of the sulcus and it is measured in millimeters at several locations around the whole circumference of the tooth.

Patient-related outcomes (pain) will be measured using visual analogue scale Minimum score 0 Maximum score 10 Higher score indicates worse outcome

Patient-related outcomes (swelling) will be measured using visual analogue scale Minimum score 0 Maximum score 10 Higher score indicates worse outcome

Patient-related outcomes (bleeding) will be measured using visual analogue scale Minimum score 0 Maximum score 10 Higher score indicates worse outcome

Patient-related outcomes (bruising) will be measured using visual analogue scale Minimum score 0 Maximum score 10 Higher score indicates worse outcome

Patient-related outcomes (root sensitivity) will be measured using visual analogue scale Minimum score 0 Maximum score 10 Higher score indicates worse outcome

Patient's quality of life will be evaluated using general oral health assessment index (GOHAI). The GOHAI has 12 negatively and positively worded items evaluating three dimensions of oral health related quality of life (physical function, pain or discomfort and psychosocial function). The score ranged from 0 to 60. The scores are maintained for the three items "able to swallow comfortably", able to eat without discomfort", "pleased with look of teeth", and reversed for the remaining nine items, so that a higher score was associated with a more positive oral health.
