Efficacy of high intensity diode laser as an adjunct to non-surgical periodontal treatment: a randomized controlled trial

Abstract

The high intensity diode laser has been studied in periodontics for the reduction of subgingival bacteria in non-surgical treatment. Our study evaluated the bacterial effect as well as changes in periodontal clinical parameters promoted by root scaling and planing associated with this wavelength. Twenty-seven patients randomly assigned in two groups underwent root scaling and planing on the tested sites, and only the experimental group received the diode laser irradiation. Among the clinical parameters studied, the clinical probing depth (CPD) and the clinical attachment level (CAL) resulted in significant enhancement in the control group when compared with the experimental group (P = 0.014 and P = 0.039, respectively). The results were similar for both groups regarding the plaque index (PI) and bleeding on probing (BP). No significant difference in the microbiological parameters was observed between the control and experimental groups. It was possible to conclude that the high power diode laser adjunct to the non-surgical periodontal treatment did not promote additional effects to the conventional periodontal treatment.

Evaluation of the serum ceruloplasmin level before and after non-surgical periodontal therapy in patients with chronic periodontitis

“…These results are in agreement with Chan and Lai [22] and De Micheli et al [23] who found significant reduction in probing pocket depth and bleeding on probing following non-surgical therapy. Also, Darby et al [24] showed that SRP resulted in improvement in the clinical attachment loss measurements mean values.…”

Effectiveness of a diode laser in addition to non-surgical periodontal therapy: study of intervention

“…Furthermore, the removal of granulation tissue infected promotes the healing of connective tissue with a decrease in probing depth, gingival index and tooth mobility and a recovery of clinical attacks significantly higher compared to the initial preparation only (33)(34)(35)(36); these results, in addition to being the best, are longer lasting and more stable over time (37). However, according to De Micheli (2011) the results of the two therapeutic procedures are similar with regard to plaque index and bleeding on probing, for which laser therapy does not lead to additional benefits (38). Also according to Dukic (2012) the results of the two treatments are similar in terms of plaque index, bleeding on probing and clinical attachment level: the addition of laser therapy showed a marked improvement in PD, but only in periodontal pockets of moderate depth (from 4 to 6 mm) (39).…”

“…How the wavelength of the various DLs are related to selective destruction of black/brown-pigment-producing bacteria [24] . Positive results both dental clinical as well as microbial using the same type of DL [25] . The reduction of pocket depth was significantly greater in the Laser group at 4-8weeks after Lasing.…”
