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.
