Probiotic strains of Lactobacillus brevis and Lactobacillus plantarum as adjunct to non-surgical periodontal therapy: 3-month results of a randomized controlled clinical trial

Purpose: To compare the effectiveness of two dental desensitization therapies, 940 nm laser diode and potassium nitrate, in patients with dental hypersensitivity (DH) symptoms. Methods: This randomized clinical trial included 30 patients who initially underwent basic periodontal therapy and presented gingival recessions Class I and II (Miller 1985) with symptoms of DH. Subjects were randomly assigned into two groups. The first group (n = 15) received laser 940 nm application for 90 seconds on the surface of the recession and were given a tube of glycerin to be applied daily in order to avoid generating bias. Patients in the second group (n = 15) were exposed to inactive laser simulating the actual application of the laser, and they were given a desensitizing gel containing 0.5 g of potassium nitrate to be applied twice daily during 14 days. Controls were carried out at 15 minutes, 8 days, 15 days, and 4 weeks. Data obtained were filled out in an Excel table. For comparison between groups the Mann Whitney U and t student tests were used (p=0.05). Results: All patients involve in the study experienced reduction in DH (p<0.01) and differences between the two interventions performed. Conclusions: Laser and nitrate therapies were effective to manage DH after basic periodontal therapy. However, a statistically significant higher sensitivity reduction was observed in laser therapy group.

ABSTRACT Aim The aim of the study was to determine and compare the pocket depths (PD), relative attachment levels (RAL), bleeding on probing (BOP) and plaque indices (PI) in patients treated with scaling and root planning (SRP) alone and along with diode laser. Materials and methods The study was carried out on 30 subjects who fulfill the inclusion and exclusion criteria. Group I: 15 patients treated with SRP along with diode laser irradiation. Group II: 15 patients treated only with SRP. The clinical parameters were probing PD, RAL, BOP and PI which were recorded at base line, 7 days and after 1 month. Statistical analysis was done using Kolmogorov-Smirnov, Shapiro-Wilk, t-test, chi-square test. Results The use of diode lasers as an adjunct to SRP during maintenance phase showed better results when compared to SRP alone. Moderate periodontal pockets with moderate attachment loss showed significant improvement in group I than in group II. There was no change in deep pockets with severe attachment loss in both groups. Clinical significance The study shows that the specified laser parameter and the modality of application of the same results in faster healing. This can be recommended as an appropriate treatment for moderate pockets. How to cite this article Suprit SS, Setty S, Thakur S.
