Assessment Of Effect Of Low- Level Laser Therapy As An Adjunct To Non- Surgical Periodontal Treatment

Abstract

Background: Periodontitis is a chronic inflammatory disease that affects the supporting structures of teeth, resulting in tooth loss. The
present study was conducted to assess the effect of low- level laser therapy as an adjunct to non- surgical periodontal treatment.
Materials & Methods:54 patients of moderate to advance periodontitis of both genders were divided into 2 groups of 27 each. Group I
comprised of patients who receivedLLLT after scaling and root planning and group II patients received scaling and root planning only.
Plaque index (PI), sulcus bleeding index (SBI), PD, and clinical attachment level (CAL) were recorded onsixsitespertoothat baseline,
1, 3, and 6 months after the treatment.
Results: Group I had 17 males and 10 females and group II had 12 males and 15 females. The mean PI at baseline was 1.82 and 1.80,
at 1 month was 0.68 and 1.02, at 3 months was 0.65 and 0.74 and at 6 months was 0.64 and 0.72 in group I and II respectively. The
mean SBI at baseline was 1.81 and 1.80, at 1 month was 0.32 and 0.50, at 3 months was 0.21 and 0.52 and at 6 months was 0.17 and
0.38 in group I and II respectively. The mean CAL at (mm) baseline was 4.53 and 4.65, at 1 month was 3.45 and 3.70 and at 3 months
was 3.40 and 3.54 and at 6 months was 3.32 and 3.50 in group I and II respectively. The mean PD (mm) at baseline was 3.90 and 4.02,
at 1 month was 2.58 and 3.04, at 3 months was 2.52 and 2.98 and at 6 months was 2.46 and 2.83 in group I and II respectively. The
difference was significant (P< 0.05).
Conclusion: Authors observed statistically significant differences on clinical parameter changes when laser was used as an adjunct to
non-surgical periodontal treatment. Thus, LLLT application may be useful in reduced gingival inflammation in patients of moderate to
severe periodontitis.
