Abstract
Chronic periodontitis has been defined as an infectious disease resulting in inflammation within the supporting structures of the teeth, progressive attachment loss, and bone loss. It is the most prevalent form of periodontitis.
Although periodontal disease is a multifactorial infectious disease, the microbial plaque is recognized as the primary etiologic agent for initiation and progression of the disease.
The chronic periodontal disease can be successfully treated by non-surgical or surgical mechanical therapy provided adequate plaque control is maintained during the supportive phase of treatment.
Since scaling and root planing has many limitations, other modalities have been proposed to be used as an adjunct to the classical treatment to fulfill the purpose.
Thus, the low-level laser was proposed as an adjunct to non-surgical periodontal therapy.
In this study 46 patients were included with bilateral clinical attachment level loss ≥2mm and ≤4mm. Split mouth design was advocated to compare the effect of non-surgical periodontal therapy alone or combined with LLLT.
The patients were diagnosed as having mild to moderate chronic periodontitis. Both males and females were included in this study with an age range from 30 to 55 years old. The selected patients were assigned in a split mouth design, one side treated by conventional therapy supragingival scaling and subgingival debridement, and the other side treated with conventional therapy combined with a diode laser. The patients were selected to be medically free to exclude all variable confounders that may affect the wound healing. The clinical parameter which included, plaque index, gingival index, bleeding index, probing depth and clinical attachment loss were recorded at baseline and at 3 months follow-up. IL-6 level was measured in the gingival crevicular fluid one week after SRP (baseline) and 3 months of follow-up in both groups
The results of this study revealed an insignificant statistical difference of PD, CAL, BI, GI, and PI between conventional treatment and low power diode laser as an adjunctive to SRP. While Interleukin-6 decreased significantly more with the low power laser in conjunction to SRP compared to SRP alone. This denotes that LLLT has a beneficial effect when used in conjunction with SRP in treating mild to moderate chronic periodontitis.
